License : BSD-3-Clause Parsing command line targets There are two relevant data sources for performing this parsing: the project configuration, and command line arguments. Project configurations includes the snapshot (defining a LoadedSnapshot of global and snapshot packages), local dependencies, and project packages. It also defines local flag overrides. The command line arguments specify both additional local flag overrides and targets in their raw form. Flags are simple: we just combine CLI flags with config flags and make one big map of flags, preferring CLI flags when present. Raw targets can be a package name, a package name with component, just a component, or a package name and version number. We first must resolve these raw targets into both simple targets and additional dependencies. This works as follows: * If a component is specified, find a unique project package which defines that component, and convert it into a name+component target. * Ensure that all name+component values refer to valid components in the given project package. * For names, check if the name is present in the snapshot, local deps, or project packages. If it is not, then look up the most recent version in the package index and convert to a name+version. * For name+version, first ensure that the name is not used by a project package. Next, if that name+version is present in the snapshot or local deps _and_ its location is PLIndex, we have the package. Otherwise, add to local deps with the appropriate PLIndex. If in either of the last two bullets we added a package to local deps, print a warning to the user recommending modifying the extra-deps. Combine the various t'ResolveResult's together into t'Target' values, by combining various components for a single package and ensuring that no conflicting statements were made about targets. At this point, we now have a Map from package name to SimpleTarget, and an updated Map of local dependencies. We still have the aggregated flags, and the snapshot and project packages. Finally, we upgrade the snapshot by using calculatePackagePromotion. -} module Stack.Build.Target ( -- * Types Target (..) , NeedTargets (..) , parseTargets -- * Convenience helpers , gpdVersion -- * Test suite exports , parseRawTarget , RawTarget (..) , UnresolvedComponent (..) , ComponentName , ResolveResult ) where import qualified Data.Map as Map import qualified Data.Set as Set import qualified Data.Text as T import Path ( isProperPrefixOf ) import Path.Extra ( forgivingResolveDir, rejectMissingDir ) import Path.IO ( getCurrentDir ) import RIO.Process ( HasProcessContext ) import Stack.SourceMap ( additionalDepPackage ) import Stack.Prelude import Stack.Types.BuildConfig ( BuildConfig (..), HasBuildConfig (..) ) import Stack.Types.BuildOptsCLI ( BuildOptsCLI (..) ) import Stack.Types.ComponentUtils ( unqualCompFromText ) import Stack.Types.Config ( Config (..) ) import Stack.Types.NamedComponent ( NamedComponent (..), renderComponent ) import Stack.Types.Build.Exception ( BuildPrettyException (..) ) import Stack.Types.ProjectConfig ( ProjectConfig (..) ) import Stack.Types.SourceMap ( DepPackage (..), GlobalPackage (..), PackageType (..) , ProjectPackage, SMActual (..), SMTargets (..) , SMWanted (..), Target (..), ppComponents, ppRoot ) -- | Do we need any targets?

We hope that the following information will encourage and assist you. We start with some advice about Stack's goals and governance, and approach to supporting users. ## Stack's goals Stack's current goals are: * To provide easy to use tooling for Haskell development * To provide complete support for at least the following three development environments: Linux, macOS, and Windows * To address the needs of industrial users, open source maintainers, and other people * To focus on the 'curated package set' use case * To prioritize reproducible build plans The goals above are not set in stone. However, any major changes to them should involve significant public discussion and a public vote by the Stack maintainer team. ## Stack's governance People involved in maintaining or developing Stack with rights to make commits to the repository can be classified into two groups: 'committers' and 'maintainers'. ### Stack's committers We encourages a wide range of people to be granted rights to make commits to the repository. People are encouraged to take initiative to make non-controversial changes, such as documentation improvements, bug fixes, performance improvements, and feature enhancements. Maintainers should be included in discussions of controversial changes and tricky code changes. Our general approach is **"it's easier to ask forgiveness than permission"**. If there is ever a bad change, it can always be rolled back. ### Stack's maintainers Stack's maintainers are long-term contributors to the project. Michael Snoyman (@snoyberg) was the founder of Stack, and its initial maintainer - and he has added others. Michael's current interests and priorities mean that he is no longer actively involved in adding new features to Stack. Maintainers are recognized for their contributions including: * Direct code contribution * Review of pull requests * Interactions on the GitHub issue tracker * Documentation management * External support - for example, hosting or training The maintainer team make certain decisions when that is necessary, specifically: * How to proceed, if there is disagreement on how to do so on a specific topic * Whether to add or remove (see further below) a maintainer Generally, maintainers are only removed due to non-participation or actions unhealthy to the project. Removal due to non-participation is not a punishment, simply a recognition that maintainership is for active participants only. We hope that removal due to unhealthy actions will never be necessary, but would include protection for cases of: * Disruptive behavior in public channels related to Stack * Impairing the codebase through bad commits/merges Like committers, maintainers are broadly encouraged to make autonomous decisions. Each maintainer is empowered to make a unilateral decision. However, maintainers should favor getting consensus first if: * They are uncertain what is the best course of action * They anticipate that other maintainers or users of Stack will disagree on the decision ## Stack's support A large part of the general discussion around Stack is on support-related topics, and that is reflected in the current issue tracker content. Assistance in responding to such matters is greatly appreciated. While support-related matters can be posted here as an 'issue', we encourage the use of other forums, in particular the [Haskell Community](https://discourse.haskell.org/) forum. See its 'Learn' category. We also recommend that forum for general discussions about Stack's current or desired features. Stack is also discussed: * in the Haskell [Stack and Stackage](https://matrix.to/#/#haskell-stack:matrix.org) room (address `#haskell-stack:matrix.org`) on [Matrix](https://matrix.org/); and * on Reddit's [Haskell community](https://www.reddit.com/r/haskell/). We encourage use of those other forums because support-related discussions can clog up the issue tracker and make it more difficult to maintain the project. People needing support may also get a faster and fuller response on other forums. Additions to the issue tracker are better suited to concrete feature proposals, bug reports, and other code base discussions (for example, refactorings). ## Bug Reports Please [open an issue](https://github.com/commercialhaskell/stack/issues/new) and use the provided template to include all necessary details. The more detailed your report, the faster it can be resolved and will ensure it is resolved in the right way. Once your bug has been resolved, the responsible person will tag the issue as _Needs confirmation_ and assign the issue back to you. Once you have tested and confirmed that the issue is resolved, close the issue. If you are not a member of the project, you will be asked for confirmation and we will close it. ## Documentation Consistent with its goal of being easy to use, Stack aims to maintain a high quality of in-tool and online documentation. The in-tool documentation includes the output when the `--help` flag is specified and the content of Stack's warning and error messages. When drafting documentation it is helpful to have in mind the intended reader and what they are assumed to know, and not know, already. In that regard, documentation should aim to meet, at least, the needs of a person who is about to begin to study computing as an undergraduate but who has not previously coded using Haskell. That person may be familiar with one popular operating system but may not be familiar with others. The files which make up Stack's online documentation are located in the `doc` directory of the repository. They are formatted in the [Markdown syntax](https://daringfireball.net/projects/markdown/), with some extensions. Those files are rendered on [haskellstack.org](http://haskellstack.org) by [Read the Docs](https://readthedocs.org/) using [MkDocs](https://www.mkdocs.org/) and the [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/) theme. The `stable` branch of the repository provides the 'stable' version of the online documentation. The `master` branch provides the 'latest' version of the documentation. The 'stable' version of the online documentation is intended to be applicable to the latest released version of Stack. If you would like to help with that documentation, please submit a [pull request](https://help.github.com/articles/using-pull-requests/) with your changes/additions based off the [stable branch](https://github.com/commercialhaskell/stack/tree/stable). The Markdown files are organised into the navigation menu (the table of contents) in the file `mkdocs.yml`, the configuration file for MkDocs. The description of a file in the menu can differ from the file's name. The navigation menu allows files to be organised in a hierarchy. Currently, up to three levels are used. The top level is: * **Welcome!:** The introduction to Stack. This page aims to be no longer than necessary but also to not assume much existing knowledge on the part of the reader. It provides a 'quick start' guide to getting and using Stack. * **How to get & use Stack:** This includes Stack's user's guide, answers to frequently asked questions, and more thorough explanations of aspects of Stack. The user's guide is divided into two parts. The first part is 'introductory', and has the style of a tutorial. The second part is 'advanced', and has more of a reference style. * **How Stack works (advanced):** Many users will not need to consult this advanced documentation. * **Stack's code (advanced):** Other information useful to people contributing to, or maintaining, Stack's code, documentation, and other files. * **Signing key:** How Stack's released executables are signed. * **Glossary:** A glossary of terms used throughout Stack's in-tool and online documentation. We aim to describe the same things in the same way in different places. * **Version history:** The log of changes to Stack between versions. The specific versions of the online documentation (eg `v: v2.9.1`) are generated from the content of files at the point in the repository's history specified by the corresponding release tag. Consequently, that content is fixed once released. If the names of Markdown files do not change between versions, then people can use the flyout on the online documentation to move between different versions of the same page. For that reason, the names of new Markdown files should be chosen with care and existing Markdown files should not be deleted or renamed without due consideration of the consequences. The Markdown syntax supported by MkDocs and the Material for MkDocs theme can differ from the GitHub Flavored Markdown ([GFM](https://github.github.com/gfm/)) supported for content on GitHub.com. Please refer to the [MkDocs documentation](https://www.mkdocs.org/user-guide/writing-your-docs/#writing-with-markdown) and the [Material for MkDocs reference](https://squidfunk.github.io/mkdocs-material/reference/) to ensure your pull request will achieve the desired rendering. The extensions to the basic Markdown syntax used are set out in `mkdocs.yml` and include: * admonitions * code blocks, with syntax highlighting provided by [Pygments](https://pygments.org/) * content tabs, which can be nested * icons and emojis The files in the `doc` directory of the repository include two symbolic links (symlinks), `ChangeLog.md` and `CONTRIBUTING.md`. Users of Git on Windows should be aware of its approach to symbolic links. See the [Git for Windows Wiki](https://github.com/git-for-windows/git/wiki/Symbolic-Links). If `git config --show-scope --show-origin core.symlinks` is `false` in a local repository on Windows, then the files will be checked out as small plain files that contain the link text See the [Git documentation](https://git-scm.com/docs/git-config#Documentation/git-config.txt-coresymlinks). The online documentation can be previewed using the `mkdocs` tool, as described in [Getting Started with MkDocs](https://www.mkdocs.org/getting-started/). The prerequisites are: * [Python](https://www.python.org/); and * the required Python packages set out in `doc/requirements.txt`. They can be installed using Python's package manager `pip` with: ~~~text pip install --requirement doc/requirements.txt ~~~ Once the required version of `mkdocs` is installed, command `mkdocs serve` in the same directory as the `mkdocs.yml` file to start a web server. The command will, eventually, output the URL at which the documentation is being served. Command `mkdocs build` to build the documentation. === "Windows" With the correct prerequisites (see further below), users of the `make` tool in the Stack-supplied MSYS2 environment can automate some of these steps from Stack's project directory with: * preview: `stack exec -- make docs-serve`; and * build: `stack exec -- make _site/index.html`. However, Windows and the Stack-supplied MSYS2 environment do not come with Python or `make` by default. Further, Python on Windows does not use the `python3` command (used on Unix-like operating systems) to invoke Python. Further still, in the MSYS2 environment, development versions of packages `libxml2` and `libxslt` are necessary dependencies. Consequently, the automation requires the following command to install requirements into the the MSYS2 environment: ~~~text stack exec -- pacman --sync python make libxml2-devel libxslt-devel ~~~ !!! note If the automation fails before the `mkdocs` tool etc is installed, the directory `.python-doc-virtualenv` created by the automation will need to be deleted before the automation will work again. For most users, the automation will be less convenient than simply using the `mkdocs serve` command directly. === "Unix-like" With `python3` and `make` available on the PATH, users of the `make` tool can automate some of these steps from Stack's project directory with: * preview: `make docs-serve`; and * build: `make _site/index.html`. ## Error messages Stack catches exceptions thrown by its dependencies or by Stack itself in `Stack.main`. In addition to exceptions that halt Stack's execution, Stack logs certain other matters as 'errors'. To support the Haskell Foundation's [Haskell Error Index](https://errors.haskell.org/) initiative, all Stack error messages generated by Stack itself should have a unique initial line: ~~~text Error: [S-nnnn] ~~~ where `nnnn` is a four-digit number in the range 1000 to 9999. If you create a new Stack error, select a number using a random number generator (see, for example, [RANDOM.ORG](https://www.random.org/)) and check that number is not already in use in Stack's code. If it is, pick another until the number is unique. All exceptions generated by Stack itself are implemented using data constructors of closed sum types. Typically, there is one such type for each module that exports functions that throw exceptions. This type and the related `instance` definitions are usually located at the top of the relevant module. Stack supports two types of exceptions: 'pretty' exceptions that are instances of class `RIO.PrettyPrint.Pretty`, which provides `pretty :: e -> StyleDoc`, and thrown as expressions of type `RIO.PrettyPrint.PrettyException.PrettyException`; and other 'plain' exceptions that are simply instances of class `Control.Exception.Exception` and, hence, instances of class `Show`. These types and classes are re-exported by `Stack.Prelude`. Stack throws exceptions in parts of the code that should, in principle, be unreachable. The functions `Stack.Prelude.bugReport` and `Stack.Prelude.bugPrettyReport` are used to give the messages a consistent format. The names of the data constructors for those exceptions usually end in `Bug`. In a few cases, Stack may throw an exception in 'pure' code. The function `RIO.impureThrow :: Exception e => e -> a`, re-exported by `Stack.Prelude`, is used for that purpose. ## Code If you would like to contribute code to fix a bug, add a new feature, or otherwise improve `stack`, pull requests are most welcome. It's a good idea to [submit an issue](https://github.com/commercialhaskell/stack/issues/new) to discuss the change before plowing into writing code. If you'd like to help out but aren't sure what to work on, look for issues with the [awaiting pull request](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3A%22awaiting+pull+request%22) label. Issues that are suitable for newcomers to the codebase have the [newcomer friendly](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3A%22awaiting+pull+request%22+label%3a%22newcomer+friendly%22) label. Best to post a comment to the issue before you start work, in case anyone has already started. Please include a [ChangeLog](https://github.com/commercialhaskell/stack/blob/master/ChangeLog.md) entry and [documentation](https://github.com/commercialhaskell/stack/tree/master/doc/) updates with your pull request. ## Backwards Compatibility The Stack package provides a library and an executable (`stack`) that depends on the library. The library is intended for use only by the executable. Consequently, the Stack package does not need to, and does not, strive for the compatibility with a range of versions of GHC that a library package (such as `pantry`) would seek. Stack aims to depend on well-known packages. The specific versions on which it depends at any time are specified by `package.yaml` and `stack.yaml`. It does not aim to be compatible with more than one version of the `Cabal` package at any time. At the time of writing (June 2025) the package versions are primarily ones in Stackage snapshot LTS Haskell 23.24 (for GHC 9.8.4) and `hpack-0.38.1`, `persistent-2.17.0.0` and `tls-2.1.8`. A Stack executable makes use of Cabal (the library) through a small 'Setup' executable that it compiles from Haskell source code. The executable compiles that code with a dependency on the version of Cabal that ships with the specified GHC compiler. Each release of Stack will normally aim to support all versions of GHC and the Cabal package in Stackage LTS Haskell snapshots published within seven years of the release. For example, snapshot LTS Haskell 12.0, published on 9 July 2018, was the first LTS Haskell snapshot to provide GHC 8.4.3 which comes with `base-4.11.1.0` and `Cabal-2.2.0.1`. Normally, until, at least, 9 July 2025, Stack releases would aim to support the immediate predecessor, GHC 8.2.2 and `base-4.10.1.0`, `Cabal-2.0.1.1` and Haddock 2.18.1. However, Stack 3.1.1 dropped support for versions of Cabal before 2.2. `Cabal-2.2.0.0` was released with GHC 8.4.1 on 8 March 2018. When a version of the Stack executable actually ceases to support a version of GHC and `Cabal`, that should be recorded in Stack's [ChangeLog](https://github.com/commercialhaskell/stack/blob/master/ChangeLog.md). ## Code Quality The Stack project uses [yamllint](https://github.com/adrienverge/yamllint) as a YAML file quality tool and [HLint](https://github.com/ndmitchell/hlint) as a code quality tool. ### Linting of YAML files The yamllint configuration extends the tools default and is set out in `.yamllint.yaml`. In particular, indentation is set at 2 spaces and `- ` in sequences is treated as part of the indentation. ### Linting of Haskell source code The HLint configurations is set out in `.hlint.yaml`. Stack contributors need not follow dogmatically the suggested HLint hints but are encouraged to debate their usefulness. If you find a HLint hint is not useful and detracts from readability of code, consider marking it in the [configuration file](https://github.com/commercialhaskell/stack/blob/master/.hlint.yaml) to be ignored. Please refer to the [HLint manual](https://github.com/ndmitchell/hlint#readme) for configuration syntax. Quoting [@mgsloan](https://github.com/commercialhaskell/stack/pulls?utf8=%E2%9C%93&q=is%3Apr%20author%3Amgsloan): > We are optimizing for code clarity, not code concision or what HLint thinks. You can install HLint with Stack. You might want to install it in the global project in case you run into dependency conflicts. HLint can report hints in your favourite text editor. Refer to the HLint repository for more details. To install, command: ~~~text stack install hlint ~~~ Once installed, you can check your changes with command: ~~~text stack exec -- sh ./etc/scripts/hlint.sh ~~~ ## Code syntax Stack makes use of GHC's `GHC2021` collection of language extensions, which is set using the `language` key in the `package.yaml` file. Stack makes use of single-constructor types where the constructor has a large number of fields. Some of those fields have similar types, and so on. Given that, Stack makes use of `OverloadedRecordDot`, introduced in GHC 9.2.1. It also makes use of `NoFieldSelectors`, also introduced in GHC 9.2.1, and, where necessary, `DuplicateRecordFields`. Together, these language extensions enable the removal from the names of fields of the prefixes that were used historically to indicate the type and make field names unique. This is because the names of fields no longer need to be unique in situations where the intended field is unambiguous. This allows for a terser syntax without loss of expressiveness. For example: ~~~haskell let cliTargets = (boptsCLITargets . bcoBuildOptsCLI) bco ~~~ can become: ~~~haskell let cliTargets = bco.buildOptsCLI.targets ~~~ The intended field is unambiguous in almost all cases. In the case of a few record updates it is ambiguous. The name of the field needs to be qualified in those cases. For example: ~~~haskell import qualified Stack.Types.Build as ConfigCache ( ConfigCache (..) ) ... let ignoreComponents :: ConfigCache -> ConfigCache ignoreComponents cc = cc { ConfigCache.components = Set.empty } ~~~ ## Code Style A single code style is not applied consistently to Stack's code and Stack is not Procrustean about matters of style. Rules of thumb, however, are: * keep pull requests that simply reformat code separate from those that make other changes to code; and * when making changes to code other than reformatting, follow the existing style of the function(s) or module(s) in question. That said, the following may help: * Stack's code generally avoids the use of C preprocessor (CPP) directives. Windows and non-Windows code is separated in separate source code directories and distinguished in Stack's Cabal file. `Stack.Constants.osIsWindows :: Bool` is provided. Multi-line strings are generally formatted on the assumption that GHC's `CPP` language pragma is not being used. * Language pragmas usually start with `NoImplictPrelude`, where applicable, and then all others are listed alphabetically. The closing `#-}` are aligned, for purely aesthetic reasons. * Stack is compiled with GHC's `-Wall` enabled, which includes `-Wtabs` (no tabs in source code). Most modules are based on two spaces (with one space for a `where`) for indentation but older and larger modules are still based on four spaces. * Stack's code and documentation tends to be based on lines of no more than 80 characters or, if longer, no longer than necessary. * Stack uses export lists. * Stack's imports are listed alphabetically, including `Stack.Prelude`, where applicable. The module names are left aligned, with space left for `qualified` where it is absent. * Stack's code is sufficiently stable that explicit import lists can sensibly be used. The exception is the import of `Stack.Prelude`. Not all modules have comprehensive explicit import lists. * Short explicit import lists follow the module name. Longer lists start on the line below the module name. Spaces are used to separate listed items from their enclosing parentheses. * As noted above, the types used to implement Stack's exceptions and the related `instance` definitions are usually located at the top of the relevant module. * In function type signatures, the `::` is kept on the same line as the function's name. This format is Haskell syntax highlighter-friendly. * If `where` is used, the declarations follow on a separate line. ## Testing The Stack code has both unit tests and integration tests. ### Working with Unit Tests Unit tests can be found in the [tests/unit](https://github.com/commercialhaskell/stack/tree/master/tests/unit) directory. Tests are written using the [Hspec](https://hspec.github.io/) framework. In order to run the full test suite, you can simply command: ~~~text stack test ~~~ The `--file-watch` is a very useful option to get quick feedback. However, running the entire test suite after each file change will slow you down. You'll need to specify which test suite (unit test or integration) and pass arguments to specify which module you'd specifically like to run to get quick feedback. A description of this follows below. If you would like to run the unit tests on their own, you can command: ~~~text stack test stack:stack-unit-test ~~~ Running an individual module works with a command like this: ~~~text stack test stack:stack-unit-test --ta "-m " ~~~ Where `` is the name of the module without `Spec.hs`. You may also load tests into GHCi and run them with these command: ~~~text stack ghci stack:stack-unit-test --only-main # GHCi starting up output ... > :main -m "" ~~~ Where again, `` is the name of the module without `Spec.hs`. ### Working with Integration Tests Integration tests can be found in the [tests/integration](https://github.com/commercialhaskell/stack/tree/master/tests/integration) folder. Running the integration tests is a little involved, you'll need to command: ~~~text stack build --flag stack:integration-tests stack --exec stack-integration-test ~~~ Running an individual module works with a command like this: ~~~text stack build --flag stack:integration-tests stack --exec "stack-integration-test -m " ~~~ Where `` is the name of the folder listed in the [test/integration/tests/](https://github.com/commercialhaskell/stack/tree/master/test/integration/tests) directory. You may also achieve this through GHCi with this command: ~~~text stack ghci stack:stack-integration-test # GHCi starting up output ... > :main -m "" ~~~ Where again, `` is the name of the folder listed in the [test/integration/tests/](https://github.com/commercialhaskell/stack/tree/master/test/integration/tests) directory. You can disable a few integration tests through the -n option : ~~~text stack build --flag stack:integration-tests stack --exec "stack-integration-test -n -n " ~~~ To disable folders named after `` and `` It's especially useful when some tests are taking a while to complete. On Linux, the `stack-integration-test` executable uses the `lld` linker and expects it to be on the PATH. The integration tests complete significantly quicker with `lld` than with the `ld.bfd` linker. ## Continuous integration (CI) We use [GitHub Actions](https://docs.github.com/en/actions) to do CI on Stack. The configuration of the workflows is in the YAML files in `.github/workflows`. The current active workflows are: ### Linting - `lint.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**` The workflow has one job (`style`). It runs on `ubuntu` only and applies yamllint and Hlint. ### Test suite - `unit-tests.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**`. * requested The workflow has two jobs: `pedantic` and `unit-tests`. The `pedantic` job runs on `ubuntu` only and builds Stack with the `--pedantic` flag. The `unit-tests` job runs on a matrix of operating systems and Stack project-level configuration files (`stack.yaml`, by default). It builds and tests Stack with the following flags: `--haddock --no-haddock-deps`. Its approach to creating a cache depends on the operating system. Its 'Cache dependencies on Unix-like OS' step caches the Stack root on Unix-like operating systems. Its 'Cache dependencies on Windows' step caches the same information on Windows, but takes into account that a relevant directory is located outside of the Stack root. ### Integration-based - `integration-tests.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**` * any tag is created * requested The workflow has three jobs: `integration-tests`, `linux-arm64` and `github-release`. The `integration-tests` job runs on a matrix of operating systems (`ubuntu`, `windows` and `macos`) and makes use of the `release.hs` script at `etc/scripts`. Its approach to creating a cache is the same as for `unit-tests.yml`, described above. Its 'Install deps and run checks' step uses `release.hs check`. Its 'Build bindist' step uses `release.hs build`. Its 'Upload bindist' step uploads artifacts using the name of the runner's operating system (`Linux`, `Windows` or `macOS`) as the name for the artifacts. The `linux-arm64` job runs on a self-hosted runner for Linux and ARM64. It makes use of Docker and a Docker file at `etc/dockerfiles/arm64.Dockerfile`. Its 'Build bindist' step makes use of a compiled version of `release.hs` script at `etc/scripts` to command `release build`. Its 'Upload bindist' step uploads artifacts using `Linux-ARM64` as the name for the artifacts. The `github-release` job needs `integration-tests` and `linux-arm64`. It only takes effect if the trigger for the workflow was the creation of a tag. Its four steps `Download Linux/Windows/macOS/Linux-ARM64 artifact` download the named artifacts to path `_release`. Its step 'Hash and sign assets' makes use of a 'secret' environment variable `RELEASE_SIGNING_KEY` established by the owner of the Stack repository. The variable contains the private key for the GPG key with ID 0x575159689BEFB442. That key is imported into GPG and then used by GPG to create a detached signature for each file. ### Stan tool - `stan.yml` [Stan](https://hackage.haskell.org/package/stan) is a Haskell static analysis tool. As of `stan-0.1.0.1`, it supports GHC >= 9.6.3 and Stack is built with GHC 9.8.4. The tool is configured by the contents of the `.stan.toml` file. This workflow will run if: * there is a pull request * requested ## Haskell Language Server You may be using [Visual Studio Code](https://code.visualstudio.com/) (VS Code) with its [Haskell extension](https://marketplace.visualstudio.com/items?itemName=haskell.haskell), which is powered by the [Haskell Language Server](https://github.com/haskell/haskell-language-server) (HLS). Stack can be built with Stack (which is recommended) or with Cabal (the tool). === "Stack" If you use Stack to build Stack, command `stack ghci` in the root directory of the Stack project should work as expected, if you have first commanded `stack build` once. `stack build` causes Cabal (the library) to create the automatically generated module `Stack_build`. If `ghc` is not on your PATH, then Haskell Language Server may report the following error about `Stack.Constants.ghcShowOptionsOutput`: ~~~text • Exception when trying to run compile-time code: ghc: readCreateProcess: does not exist (No such file or directory) Code: (TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) • In the untyped splice: $(TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) ~~~ `ghc` should be on the PATH if you run VS Code itself in the Stack environment: ~~~text stack exec -- code . ~~~ The following [cradle (`hie.yaml`)](https://github.com/haskell/hie-bios) should suffice to configure Haskell Language Server (HLS) explicitly for `./Setup.hs` and each of the buildable components in Stack's Cabal file: ~~~yaml cradle: multi: - path: "./Setup.hs" config: cradle: direct: arguments: [] - path: "./" config: cradle: stack: - path: "./src" component: "stack:lib" - path: "./app" component: "stack:exe:stack" - path: "./tests/integration" component: "stack:exe:stack-integration-test" - path: "./tests/unit" component: "stack:test:stack-unit-test" ~~~ === "Cabal (the tool)" If you use Cabal (the tool) to build Stack, command `cabal repl` in the root directory of the Stack project should work as expected, if you have GHC and (on Windows) MSYS2 on the PATH. Stack's custom `./Setup.hs` causes `cabal repl` to cause Cabal (the library) to create the automatically generated module `Stack_build`. If `ghc` is not on your PATH, then Haskell Language Server may report the following error about `Stack.Constants.ghcShowOptionsOutput`: ~~~text • Exception when trying to run compile-time code: ghc: readCreateProcess: does not exist (No such file or directory) Code: (TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) • In the untyped splice: $(TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) ~~~ `ghc` and (on Windows) MSYS2 should be on the PATH if you run commands (including `cabal`) in the Stack environment: ~~~text stack exec --no-ghc-package-path -- cabal repl ~~~ or ~~~text stack exec --no-ghc-package-path -- code . ~~~ Use of GHC's environment variable `GHC_PACKAGE_PATH` is not compatible with Cabal (the tool). That is why the `--no-ghc-package-path` flag must be specified with `stack exec` when relying on Cabal (the tool). The following [cradle (`hie.yaml`)](https://github.com/haskell/hie-bios) should suffice to configure Haskell Language Server (HLS) explicitly for `./Setup.hs` and each of the buildable components in Stack's Cabal file: ~~~yaml cradle: multi: - path: "./Setup.hs" config: cradle: direct: arguments: [] - path: "./" config: cradle: cabal: - path: "./src" component: "lib:stack" - path: "./app" component: "exe:stack" - path: "./tests/integration" component: "exe:stack-integration-test" - path: "./tests/unit" component: "test:stack-unit-test" ~~~ A cradle is not committed to Stack's repository because it imposes a choice of tool used for building. ## Dev Containers A [Development Container](https://containers.dev) (or Dev Container for short) allows you to use a container as a full‑featured development environment. You can run Dev Containers locally/remotely (with VS Code), or create a [Codespace](https://github.com/features/codespaces) for a branch in a repository to develop online. Stack's default Dev Container is intended for use with its default project‑level configuration (`stack.yaml`). But there are also Dev Containers for the experimental project‑level configurations. For further information, see the documentation for [Dev Containers](dev_containers.md). ## Slack channel If you're making deep changes and real-time communication with the Stack team would be helpful, we have a `#stack-collaborators` Slack channel in the Haskell Foundation workspace. To join the workspace, follow this [link](https://haskell-foundation.slack.com/join/shared_invite/zt-z45o9x38-8L55P27r12YO0YeEufcO2w#/shared-invite/email). ## Matrix room There is also a [Haskell Stack room](https://matrix.to/#/#haskell-stack:matrix.org) at address `#haskell-stack:matrix.org` on [Matrix](https://matrix.org/). stack-3.7.1/ChangeLog.md0000644000000000000000000054137015030022424013170 0ustar0000000000000000# Changelog ## v3.7.1 - 2025-06-28 **Changes since v3.5.1:** Other enhancements: * Bump to Hpack 0.38.1. * The `--extra-dep` option of Stack's `script` command now accepts a YAML value specifying any immutable extra-dep. Previously only an extra-dep in the package index that could be specified by a YAML string (for example, `acme-missiles-0.3@rev:0`) was accepted. Bug fixes: * `stack script --package ` now uses GHC's `-package-id` option to expose the installed package, rather than GHC's `-package` option. For packages with public sub-libraries, `-package ` can expose an installed package other than one listed by `ghc-pkg list `. * Work around `ghc-pkg` bug where, on Windows only, it cannot register a package into a package database that is also listed in the `GHC_PACKAGE_PATH` environment variable. In previous versions of Stack, this affected `stack script` when copying a pre-compiled package from another package database. * On Windows, when decompressing, and extracting tools, from archive files, Stack uses the system temporary directory, rather than the root of the destination drive, if the former is on the destination drive. ## v3.5.1 - 2025-03-29 **Changes since v3.3.1:** Behavior changes: * Stack will also warn (message S-8432) if there is any non-ISO/IEC 8859-1 (Latin-1) character in Stack's 'programs' path, as `hsc2hs` does not work if there is such a character in the path to its default template `template-hsc.h`. * Stack customizes setup using `Cabal`, so if a `setup-depends` field does not mention it as a dependency, Stack warns and adds the GHC boot package as a dependency. Previously, Stack would not do so but only warn that build errors were likely. Other enhancements: * Bump to Hpack 0.38.0. * In YAML configuration files, the `install-msys` key is introduced, to enable or disable the download and installation of Stack-supplied MSYS2 when necessary (subject to `skip-msys: false`). The default is the same as the `install-ghc` setting (including if that is set at the command line). Consequently, the default behaviour of Stack is unaffected. * Add the `stack config set install-msys` command to configure the `install-msys` option in YAML configuration files. * Option `allow-newer-deps` is no longer classified as experimental in documentation. * `stack sdist` and `stack upload` report the version of Cabal (the library) being used to check packages. * Add the `stack config build-files` command to generate (when applicable) a Cabal file from a package description in the Hpack format and/or a lock file for Stack's project-level configuration, without taking any other build steps. ## v3.3.1 - 2024-12-28 **Changes since v3.1.1:** Behavior changes: * Stack interprets consecutive line ends in the value of the `user-message` project-specific configuration option as a single blank line. Previously all line ends were interpreted as white space. * Stack no longer supports Docker versions before Docker 1.9.1 and, consequently, if a Docker container is not being run 'detached', its standard input channel will always be kept open. (Before Docker 1.9.1 the use of an interactive container could hang in certain circumstances.) * On Windows, Stack will always warn (message S-8432) if there is a space character in Stack's 'programs' path, as GHC 9.4.1 and later do not work if there is a space in the path to the `ghc` executable. S-8432 now presents as a warning and not an error. * Stack respects the `--no-run-tests` and `--no-run-benchmarks` flags when determining build actions. Previously Stack respected the flags when executing the run test suites or run benchmarks actions for each targeted project package. Other enhancements: * Consider GHC 9.10 to be a tested compiler and remove warnings. * Consider Cabal 3.12 to be a tested library and remove warnings. * Add flags `--run-tests` and `--run-benchmarks` (the existing defaults) to Stack's `build` command, which take precedence over the existing `no-run-tests` and `no-run-benchmarks` configuration options, respectively. * In configuration files, the `notify-if-no-run-tests` and `notify-if-no-run-benchmarks` keys are introduced, to allow the exisitng notification to be muted if unwanted. Bug fixes: * Stack's in-app messages refer to https://haskellstack.org as currently structured. (Most URLs in older Stack versions are redirected.) * Stack's `upgrade` command only treats the current running Stack executable as '`stack`' if the executable file is named `stack` or, on Windows, `stack.exe`. Previously only how it was invoked was considered. * `stack test --no-run-tests --dry-run` no longer reports that Stack would test project packages with test suites and `stack bench --no-run-benchmarks --dry-run` no longer reports that Stack would benchmark project packages with benchmarks. * `StackSetupShim` compiles with `Cabal >= 3.14.0.0`. ## v3.1.1 - 2024-07-28 Release notes: * The change in major version from 2.x to 3.1 marks the dropping of support for versions of GHC before 8.4, deprecated in Stack 2.15.1. **Changes since v2.15.7:** Behavior changes: * Stack uses the version of the Cabal package that comes with the specified version of GHC. Stack no longer supports such Cabal versions before 2.2, which came with versions of GHC before 8.4. Consequently, the `init` command will not try LTS Haskell before 12.0. * The `init` command initialises `stack.yaml` with a `snapshot` key rather than a `resolver` key. * After installing GHC or another tool, Stack deletes the archive file which provided the tool. * Remove hidden flag `--skip-intermediate-deps`, effectively deprecated since Stack 1.3.0, from `ghci` and `repl` commands. * The `haddock --haddock-for-hackage` command only seeks to create an archive of the `-docs` directory for build targets and if flags excluding the building of project packages are not set. * The predecessor of configuration option `package-index`, `package-indices` (deprecated in Stack 2.9.3) has been removed as an alternative option. * If a build target is a package identifier, and the package version is not in the snapshot or the package index, Stack will report an error when the target is parsed. Previously, if another version of the package was in the snapshot, Stack would construct the build plan with that other version or, if it was not, Stack would defer an error to the construction of the build plan. * The `list` command, with a specified snapshot and package, also reports the version of the package included indirectly in the snapshot (as a boot package of the compiler specified by the snapshot). * `stack build --flag *:[-]` now only applies the flag setting to packages for which the Cabal flag is defined, as opposed to all packages. * On Unix-like operating systems, drop support for `/etc/stack/config`, deprecated in Stack 0.1.6.0. * Drop support for, in the Stack root, directory `global` and file `stack.yaml`, both deprecated in Stack 0.1.6.0. Other enhancements: * Bump to Hpack 0.37.0. * In YAML configuration files, the `msys-environment` key is introduced to allow, on Windows, the MSYS2 environment to be specified. The default environment is still `MINGW64` on 64-bit Windows and `MINGW32` on 32-bit Windows. * In YAML configuration files, the `default-init-snapshot` key is introduced to allow a default snapshot to be specified for use with the `stack init` command, as if it had been specified at the command line. * Add flags `--haddock-executables`, `--haddock-tests` and `--haddock-benchmarks` to Stack's `build` command (including the `haddock` synonym for `build --haddock`) to enable also building Haddock documentation for executables, test suites and benchmarks. Due to a bug in Cabal (the library), Stack will ignore the flags with a warning for GHC versions before 9.4. * Add flag `--[no-]save-hackage-creds` to Stack's `upload` command, which takes precedence over the existing `save-hackage-creds` configuration option. * In YAML configuration files, the `global-hints-location` key is introduced to allow the location of the global hints YAML specification file to be specified. * By default, Hpack 0.20.0 or later will decline to overwrite a Cabal file that was modified manually. In YAML configuration files, the `hpack-force` key is introduced to allow Hpack to overwrite such a Cabal file. The corresponding `--hpack-force` flag is also added. * Add the `stack config set recommend-stack-upgrade` command to configure whether or not Stack should notify the user if it identifes a new version of Stack is available in YAML configuration files. * Add the `ls globals` command to list all global packages for the version of GHC specified by the snapshot. * Add `stack -h` (equivalent to `stack --help`). * In YAML configuration files, the `file-watch-hook` key is introduced to allow `--file-watch` post-processing to be customised with a executable or `sh` shell script. * Add flag `--[no-]allow-newer` to Stack's `build` command, which takes precedence over the existing `allow-newer` configuration option. Bug fixes: * The `config set snapshot` and `config set resolver` commands now respect the presence of a synoymous key. * The `config set` commands support existing keys only in the form `key: value` on a single line. The commands now recognise that a line `key:` does not have that form. * On Unix-like operating systems, the `test --coverage` command now finds package keys even for very long package names. * The Error S-6362 message now acknowledges when the wanted compiler has been specified at the command line. * Fix a regression, introduced in Stack 2.11.1, that caused the `script` command to parse an (otherwise ignored) project-level configuration file. * Stack no longer makes recommendations about a project-level configuration file when only a global configuration file is in use. * Fix a regression, introduced in Stack 2.15.7, that caused GHC 8.10.7 or earlier to fail to build a package with a `Custom` build type, if GHC option `-haddock` was specified. ## v2.15.7 - 2024-05-12 Release notes: * This release fixes potential bugs. * The hash that Stack uses to distinguish one build plan from another has changed for plans that set (as opposed to unset) manually Cabal flags for immutable dependencies. This will cause Stack to rebuild dependencies for such plans. **Changes since v2.15.5:** Major changes: * Stack 2.15.5 and earlier cannot build with Cabal (the library) version `3.12.0.0`. Stack can now build with that Cabal version. Behavior changes: * Stack's `StackSetupShim` executable, when called with `repl` and `stack-initial-build-steps`, no longer uses Cabal's `replHook` to apply `initialBuildSteps` but takes a more direct approach. Bug fixes: * Fix a regression introduced in Stack 2.15.1 that caused a 'no operation' `stack build` to be slower than previously. * The hashes that Stack uses to distinguish one build plan from another now include the Cabal flags for immutable dependencies set manually. Previously, in error, only such flags that were unset manually were included. ## v2.15.5 - 2024-03-28 Release notes: * This release fixes potential bugs. **Changes since v2.15.3:** Behavior changes: * Following the handover of the Stackage project to the Haskell Foundation, the default value of the `urls` key is `latest-snapshot: https://stackage-haddock.haskell.org/snapshots.json`. * Stack no longer includes the snapshot package database when compiling the setup executable for a package with `build-type: Configure`. ## v2.15.3 - 2024-03-07 Release notes: * With one exception, this release fixes bugs. **Changes since v2.15.1:** Behavior changes: * `stack path --global-config`, `--programs`, and `--local-bin` no longer set up Stack's environment. Bug fixes: * Due to a bug, Stack 2.15.1 did not support versions of GHC before 8.2. Stack now supports GHC versions from 8.0. * `--haddock-for-hackage` does not ignore `--haddock-arguments`. * On Windows, package locations that are Git repositories with submodules now work as intended. * The `ghc`, `runghc` and `runhaskell` commands accept `--package` values that are a list of package names or package identifiers separated by spaces and, in the case of package identifiers, in the same way as if they were specified as targets to `stack build`. ## v2.15.1 - 2024-02-09 Release notes: * After an upgrade from an earlier version of Stack, on first use only, Stack 2.15.1 may warn that it had trouble loading the CompilerPaths cache. * The hash used as a key for Stack's pre-compiled package cache has changed, following the dropping of support for Cabal versions older than `1.24.0.0`. **Changes since v2.13.1:** Behavior changes: * Stack does not leave `*.hi` or `*.o` files in the `setup-exe-src` directory of the Stack root, and deletes any corresponding to a `setup-.hs` or `setup-shim-.hs` file, to avoid GHC issue [#21250](https://gitlab.haskell.org/ghc/ghc/-/issues/21250). * If Stack's Nix integration is not enabled, Stack will notify the user if a `nix` executable is on the PATH. This usually indicates the Nix package manager is available. In YAML configuration files, the `notify-if-nix-on-path` key is introduced, to allow the notification to be muted if unwanted. * Drop support for Intero (end of life in November 2019). * `stack path --stack-root` no longer sets up Stack's environment and does not load Stack's configuration. * Stack no longer locks on configuration, so packages (remote and local) can be configured in parallel. This increases the effective concurrency of builds that before would use fewer threads. Reconsider your `--jobs` setting accordingly. See [#84](https://github.com/commercialhaskell/stack/issues/84). * Stack warns that its support for Cabal versions before `2.2.0.0` is deprecated and may be removed in the next version of Stack. Removal would mean that projects using snapshots earlier than `lts-12.0` or `nightly-2018-03-18` (GHC 8.4.1) might no longer build. See [#6377](https://github.com/commercialhaskell/stack/issues/6377). * If Stack's `--resolver` option is not specified, Stack's `unpack` command with a package name will seek to update the package index before seeking to download the most recent version of the package in the index. * If the version of Cabal (the library) provided with the specified GHC can copy specific components, Stack will copy only the components built and will not build all executable components at least once. Other enhancements: * Consider GHC 9.8 to be a tested compiler and remove warnings. * Stack can build packages with dependencies on public sub-libraries of other packages. * Add flag `--no-init` to Stack's `new` command to skip the initialisation of the newly-created project for use with Stack. * The HTML file paths produced at the end of `stack haddock` are printed on separate lines and without a trailing dot. * Add option of the form `--doctest-option=` to `stack build`, where `doctest` is a program recognised by versions of the Cabal library from `1.24.0.0`. * Experimental: Add flag `--haddock-for-hackage` to Stack's `build` command (including the `haddock` synonym for `build --haddock`) to enable building project packages with flags to generate Haddock documentation, and an archive file, suitable for upload to Hackage. The form of the Haddock documentation generated for other packages is unaffected. * Experimental: Add flag `--documentation` (`-d` for short) to Stack's `upload` command to allow uploading of documentation for packages to Hackage. * `stack new` no longer rejects project templates that specify a `package.yaml` in a subdirectory of the project directory. * Stack will notify the user if Stack has not been tested with the version of GHC that is being user or a version of Cabal (the library) that has been found. In YAML configuration files, the `notify-if-ghc-untested` and `notify-if-cabal-untested` keys are introduced, to allow the notification to be muted if unwanted. * The compiler version is included in Stack's build message (e.g. `stack> build (lib + exe + test) with ghc-9.6.4`). * Add flag `--candidate` to Stack's `unpack` command, to allow package candidates to be unpacked locally. * Stack will notify the user if a specified architecture value is unknown to Cabal (the library). In YAML configuration files, the `notify-if-arch-unknown` key is introduced, to allow the notification to be muted if unwanted. * Add option `--filter ` to Stack's `ls dependencies text` command to filter out an item from the results, if present. The item can be `$locals` for all project packages. * Add option `--snapshot` as synonym for `--resolver`. * Add the `config set snapshot` command, corresponding to the `config set resolver` command. Bug fixes: * Fix the `Curator` instance of `ToJSON`, as regards `expect-haddock-failure`. * Better error message if a `resolver:` or `snapshot:` value is, in error, a YAML number. * Stack accepts all package names that are, in fact, acceptable to Cabal. * Stack's `sdist` command can check packages with names that include non-ASCII characters. ## v2.13.1 - 2023-09-29 Release notes: * Further to the release notes for Stack 2.3.1, the `-static` suffix has been removed from the statically-linked Linux/x86_64 executables. * The executables for Linux/Aarch64 are now statically-linked. * Executables are now provided for macOS/AArch64. **Changes since v2.11.1:** Behavior changes: * Build artefacts are placed in `.stack-work/dist//` (hashed to a shorter path on Windows), rather than `.stack-work/dist//`. This allows build artifacts to be distinguished by GHC version. * By default, the `stack build` progress bar is capped to a length equal to the terminal width. * When building GHC from source, Stack no longer uses Hadrian's deprecated `--configure`\\`-c` flag and, instead, seeks to run GHC's Python `boot` and sh `configure` scripts, and ensure that the `happy` and `alex` executables are on the PATH. * When auto-detecting `--ghc-build` on Linux, the `musl` GHC build only is considered a possible GHC build if `libc.musl-x86_64.so.1` is found in `\lib` or `\lib64`. * No longer supports Cabal versions older than `1.24.0.0`. This means projects using snapshots earlier than `lts-7.0` or `nightly-2016-05-26` (GHC 8.0.1) will no longer build. GHC 8.0.1 comes with Haddock 2.17.2. * When unregistering many packages in a single step, Stack can now do that efficiently. Stack no longer uses GHC-supplied `ghc-pkg unregister` (which is, currently, slower). * `stack hpc report`, `stack list`, `stack templates` and `stack uninstall` output their information to the standard output stream rather than to the standard error stream. Logging is still to the standard error stream. * `stack upgrade` no longer assumes that binary upgrade is not supported on a AArch64 machine architecture. Other enhancements: * Consider GHC 9.6 to be a tested compiler and remove warnings. * Consider Cabal 3.10 to be a tested library and remove warnings. * Bump to Hpack 0.36.0. * Depend on `pantry-0.9.2`, for support for long filenames and directory names in archives created by `git archive`. * Avoid the duplicate resolving of usage files when parsing `*.hi` files into a set of modules and a collection of resolved usage files. See [#6123](https://github.com/commercialhaskell/stack/pull/6123). * Add composable component type flags `--exes`, `--tests` and `--benchmarks` to Stack's `ide targets` command, to list only those components. * `stack --verbose` excludes lengthy information about build plan construction in the debug output by default. The new `stack --[no-]plan-in-log` flag enables or disables the inclusion of the information in the debug output. * In YAML configuration files, the `casa` key is introduced, which takes precedence over the existing `casa-repo-prefix` key. The latter is deprecated. The new key also allows Stack's use of a Casa (content-addressable storage archive) server to be disabled and the maximum number of keys per request to be configured. The default Casa prefix references https://casa.stackage.org, instead of https://casa.fpcomplete.com. * Add option `--progress-bar=` to Stack's `build` command to configure the format of the progress bar, where `` is one of `none`, `count-only` (only the package count), `capped` (capped to a length equal to the terminal width) and `full` (the previous format). Bug fixes: * Restore `stack sdist --pvp-bounds lower` (broken with Stack 2.9.1). * Restore building of Stack with Cabal flag `disable-git-info` (broken with Stack 2.11.1). * With `stack hoogle`, avoid the message `Minimum version is hoogle-5.0. Found acceptable hoogle- in your index, requiring its installation.` when a `hoogle` executable has already been found on the `PATH`. * Stack's sanity check on a selected GHC now passes GHC flag `-hide-all-packages`, stopping GHC from looking for a package environment in default locations. * Restore Stack script files without extensions (broken with Stack 2.11.1). * Restore message suffix `due to warnings` with `dump-logs: warning` (broken with Stack 2.11.1). * On Windows, the `local-programs-path` directory can now be on a different drive to the system temporary directory and MSYS2 will still be installed. ## v2.11.1 - 2023-05-18 **Changes since v2.9.3:** Behavior changes: * Add flag `--[no-]-only-local-bin` to Stack's `upgrade` command for a binary upgrade. If the Stack executable is `my-stack`, the default is `my-stack upgrade --only-local-bin` where previously it was, effectively, `my-stack upgrade --no-only-local-bin`. If the Stack executable is `stack`, the default is `stack upgrade --no-only-local-bin`, the same behaviour as previously. * Use `$XDG_CACHE_HOME/stack/ghci-script`, rather than `/haskell-stack-ghci` (where `` is the directory yielded by the `temporary` package's `System.IO.Temp.getCanonicalTemporaryDirectory`), as the base location for GHCi script files generated by `stack ghci` or `stack repl`. See [#5203](https://github.com/commercialhaskell/stack/issues/5203) * Drop support for `Cabal` versions before 1.22 and, consequently, GHC versions before 7.10. * `stack ghci` and `stack repl` now take into account the values of `default-language` fields in Cabal files, like they take into account the values of `default-extensions` fields. * Removed `--ghc-paths`, `--global-stack-root` and `--local-bin-path` flags for `stack path`, deprecated in Stack 1.1.0 in favour of `--programs`, `--stack-root` and `local-bin` respectively. * On Windows, `stack upgrade` always renames the file of the running Stack executable (adding extension `.old`) before attempting to write to the original file name. * On Windows, `stack upgrade` does not offer `sudo` command alternatives if attempting to write to the original file name of the running Stack exectuable results in a 'Permission' error. * On Linux, Stack's `setup` command now distinguishes GHC build `tinfo6-libc6-pre232` from existing `tinfo6`. The former refers to systems where the version of `libc6` (the GNU C Library) is not compatible with version 2.32. `tinfo6-libc6-pre232` is now a possible value for the `ghc-build` configuration option. Other enhancements: * Add options of the form `--PROG-option=` to `stack build`, where `PROG` is a program recognised by the Cabal library and one of `alex`, `ar`, `c2hs`, `cpphs`, `gcc`, `greencard`, `happy`, `hsc2hs`, `hscolour`, `ld`, `pkg-config`, `strip` and `tar`. If Cabal uses the program during the configuration step, the argument is passed to it. * By default all `--PROG-option` options are applied to all project packages. This behaviour can be changed with new configuration option `apply-prog-options`. * Add flag `--[no-]use-root` to `stack script` (default disabled). Used with `--compile` or `--optimize`, when enabled all compilation outputs (including the executable) are written to a script-specific location in the `scripts` directory of the Stack root rather than the script's directory, avoiding clutter of the latter directory. * Better error message if the value of the `STACK_WORK` environment variable or `--work-dir` option is not a valid relative path. * Stack will use the value of the `GH_TOKEN`, or `GITHUB_TOKEN`, environment variable as credentials to authenticate its GitHub REST API requests. * `stack uninstall` also shows how to uninstall Stack-supplied tools. Bug fixes: * Fix incorrect warning if `allow-newer-deps` are specified but `allow-newer` is `false`. See [#6068](https://github.com/commercialhaskell/stack/issues/6086). * `stack build` with `--file-watch` or `--file-watch-poll` outputs 'pretty' error messages, as intended. See [#5978](https://github.com/commercialhaskell/stack/issues/5978). * `stack build` unregisters any project packages for the sub libraries of a project package that is to be unregistered. See [#6046](https://github.com/commercialhaskell/stack/issues/6046). * The warning that sublibrary dependency is not supported is no longer triggered by internal libraries. ## v2.9.3.1 - 2023-06-22 Hackage-only release of the `stack` package: * Supports building against snapshot Stackage LTS Haskell 21.0 (GHC 9.4.5), without extra-deps. * Supports build with `persistent-2.14.5.0`, using CPP directives. * Supports build with `unix-compat-0.7`, by removing reliance on the module `System.PosixCompat.User` removed in that package. * Includes `cabal.project` and `cabal.config` files in the package. ## v2.9.3 - 2022-12-16 **Changes since v2.9.1:** Behavior changes: * In YAML configuration files, the `package-index` key is introduced which takes precedence over the existing `package-indices` key. The latter is deprecated. * In YAML configuration files, the `hackage-security` key of the `package-index` key or the `package-indices` item can be omitted, and the Hackage Security configuration for the item will default to that for the official Hackage server. See [#5870](https://github.com/commercialhaskell/stack/issues/5870). * Add the `stack config set package-index download-prefix` command to set the location of Stack's package index in YAML configuration files. * `stack setup` with the `--no-install-ghc` flag warns that the flag and the command are inconsistent and now takes no action. Previously the flag was silently ignored. * To support the Haskell Foundation's [Haskell Error Index](https://errors.haskell.org/) initiative, all Stack error messages generated by Stack itself begin with an unique code in the form `[S-nnnn]`, where `nnnn` is a four-digit number. * Test suite executables that seek input on the standard input stream (`stdin`) will not throw an exception. Previously, they would thow an exception, consistent with Cabal's 'exitcode-stdio-1.0' test suite interface specification. Pass the flag `--no-tests-allow-stdin` to `stack build` to enforce Cabal's specification. See [#5897](https://github.com/commercialhaskell/stack/issues/5897) Other enhancements: * Help documentation for `stack upgrade` warns that if GHCup is used to install Stack, only GHCup should be used to upgrade Stack. That is because GHCup uses an executable named `stack` to manage versions of Stack, that Stack will likely overwrite on upgrade. * Add `stack ls dependencies cabal` command, which lists dependencies in the format of exact Cabal constraints. * Add `STACK_XDG` environment variable to use the XDG Base Directory Specification for the Stack root and Stack's global YAML configuration file, if the Stack root location is not set on the command line or by using the `STACK_ROOT` environment variable. * Add `stack path --global-config`, to yield the full path of Stack's user-specific global YAML configuration file (`config.yaml`). * Experimental: Add option `allow-newer-deps`, which allows users to specify a subset of dependencies for which version bounds should be ignored (`allow-newer-deps: ['foo', 'bar']`). This key has no effect unless `allow-newer` is enabled. Bug fixes: * Fix ambiguous module name `Distribution.PackageDescription`, if compiling `StackSetupShim` with `Cabal-syntax-3.8.1.0` in package database. See [#5886](https://github.com/commercialhaskell/stack/pull/5886). * In YAML configuration files, if the `package-indices` key (or the `hackage-security` key of its item) is omitted, the expiration of timestamps is now ignored, as intended. See Pantry [#63](https://github.com/commercialhaskell/pantry/pull/63) ## v2.9.1 - 2022-09-19 **Changes since v2.7.5:** Release notes: * After an upgrade from an earlier version of Stack, on first use only, Stack 2.9.1 may warn that it had trouble loading the CompilerPaths cache. * The support from the Stack team for executable releases now includes Linux/AArch64 and is limited to: * Linux 64-bit/x86_64 (statically-linked) * Linux AArch64 (dynamically-linked) * macOS x86_64 * Windows 64-bit/x86_64 Behavior changes: * `stack build --coverage` will generate a unified coverage report, even if there is only one `*.tix` file, in case a package has tested the library of another package that has not tested its own library. See [#5713](https://github.com/commercialhaskell/stack/issues/5713) * `stack --verbose` no longer includes the lengthy raw snapshot layer (rsl) in the debug output by default. The new `stack --[no-]rsl-in-log` flag enables or disables the inclusion of the rsl in the debug output. Other enhancements: * Consider GHC 9.2 and 9.4 to be tested compilers and remove warnings. * Consider Cabal 3.6 and 3.8 to be a tested libraries and remove warnings. * Bump to Hpack 0.35.0. * On Windows, the installer now sets `DisplayVersion` in the registry, enabling tools like `winget` to properly read the version number. * Adds flag `--script-no-run-compile` (disabled by default) that uses the `--no-run` option with `stack script` (and forces the `--compile` option). This enables a command like `stack --script-no-run-compile Script.hs` to behave like `stack script --no-run --compile -- Script.hs` but without having to list all the `` in the Stack interpreter options comment in `Script.hs` on the command line. That may help test that scripts compile in CI (continuous integration). See [#5755](https://github.com/commercialhaskell/stack/issues/5755) * Fuller help is provided at the command line if a subcommand is missing (for example, `stack ls` now yields the equivalent of `stack ls --help`). See [#809](https://github.com/commercialhaskell/stack/issues/809) * Add build option `--cabal-verbosity=VERBOSITY` to specify the Cabal verbosity level (the option accepts Cabal's numerical and extended syntax). See [#1369](https://github.com/commercialhaskell/stack/issues/809) * Add the possibility of a `sh` script to customise fully GHC installation. See [#5585](https://github.com/commercialhaskell/stack/pull/5585) * `tools` subcommand added to `stack ls`, to list stack's installed tools. * `stack uninstall` shows how to uninstall Stack. * `--ghc-variant` accepts `int-native` as a variant. Bug fixes: * Fix `stack clean --full`, so that the files to be deleted are not in use. See [#5714](https://github.com/commercialhaskell/stack/issues/5714) * Fix an inconsistency in the pretty formatting of the output of `stack build --coverage` * Fix repeated warning about missing parameters when using `stack new` * Include `pantry-0.5.6`: Remove operational and mirror keys from bootstrap key set [#53](https://github.com/commercialhaskell/pantry/pull/53) * Pass any CPP options specified via `cpp-options:` in the Cabal file to GHCi using GHC's `-optP` flag. See [#5608](https://github.com/commercialhaskell/stack/pull/5608) * On Unix-like operating systems, respect the `with-gcc` option when installing GHC. See [#5609](https://github.com/commercialhaskell/stack/pull/5609) * Fixed logic in `get_isa()` in `get-stack.sh` to exclude systems that don't have x86 in their `uname -m` output. See [5792](https://github.com/commercialhaskell/stack/issues/5792). * Fixed output of `stack ls snapshots local` on Windows, to behave like that on Unix-like operating systems. * Fix non-deterministic test failures when executing a test suite for a multi-project repository with parallelism enabled. See [#5024](https://github.com/commercialhaskell/stack/issues/5024) ## v2.7.5 - 2022-03-06 **Changes since v2.7.3:** Behavior changes: * Cloning git repositories isn't per sub-directory anymore, see [#5411](https://github.com/commercialhaskell/stack/issues/5411) Other enhancements: * `stack setup` supports installing GHC for macOS/AArch64 (M1) * `stack upload` supports authentication with a Hackage API key (via `HACKAGE_KEY` environment variable). Bug fixes: * Ensure that `extra-path` works for case-insensitive `PATH`s on Windows. See [rio#237](https://github.com/commercialhaskell/rio/pull/237) * Fix handling of overwritten `ghc` and `ghc-pkg` locations. [#5597](https://github.com/commercialhaskell/stack/pull/5597) * Fix failure to find package when a dependency is shared between projects. [#5680](https://github.com/commercialhaskell/stack/issues/5680) * `stack ghci` now uses package flags in `stack.yaml` [#5434](https://github.com/commercialhaskell/stack/issues/5434) ## v2.7.3 - 2021-07-20 **Changes since v2.7.1:** Other enhancements: * `stack upgrade` will download from `haskellstack.org` before trying `github.com`. See [#5288](https://github.com/commercialhaskell/stack/issues/5288) * `stack upgrade` makes less assumptions about archive format. See [#5288](https://github.com/commercialhaskell/stack/issues/5288) * Add a `--no-run` flag to the `script` command when compiling. Bug fixes: * GHC source builds work properly for recent GHC versions again. See [#5528](https://github.com/commercialhaskell/stack/issues/5528) * `stack setup` always looks for the unpacked directory name to support different tar file naming conventions. See [#5545](https://github.com/commercialhaskell/stack/issues/5545) * Bump `pantry` version for better OS support. See [pantry#33](https://github.com/commercialhaskell/pantry/issues/33) * When building the sanity check for a new GHC install, make sure to clear `GHC_PACKAGE_PATH`. * Specifying GHC RTS flags in the `stack.yaml` no longer fails with an error. [#5568](https://github.com/commercialhaskell/stack/pull/5568) * `stack setup` will look in sandboxed directories for executables, not relying on `findExecutables. See [GHC issue 20074](https://gitlab.haskell.org/ghc/ghc/-/issues/20074) * Track changes to `setup-config` properly to avoid reconfiguring on every change. See [#5578](https://github.com/commercialhaskell/stack/issues/5578) ## v2.7.1 - 2021-05-07 **Changes since v2.5.1.1:** Behavior changes: * `stack repl` now always warns about GHCi problems with loading multiple packages. It also sets now proper working directory when invoked with one package. See [#5421](https://github.com/commercialhaskell/stack/issues/5421) * `custom-setup` dependencies are now properly initialized for `stack dist`. This makes `explicit-setup-deps` no longer required and that option was removed. See [#4006](https://github.com/commercialhaskell/stack/issues/4006) Other enhancements: * Consider GHC 9.0 to be a tested compiler and remove warnings. * Consider Cabal 3.6 to be a tested library and remove warnings. * Nix integration now passes `ghcVersion` (in addition to existing `ghc`) to `shell-file` as an identifier that can be looked up in a compiler attribute set. * Nix integration now allows Nix integration if the user is ready in nix-shell. This gets rid of "In Nix shell but reExecL is False" error. * `stack list` is a new command to list package versions in a snapshot. See [#5431](https://github.com/commercialhaskell/stack/pull/5431) * `custom-preprocessor-extensions` is a new configuration option for allowing Stack to be aware of any custom preprocessors you have added to `Setup.hs`. See [#3491](https://github.com/commercialhaskell/stack/issues/3491) * Added `--candidate` flag to `upload` command to upload a package candidate rather than publishing the package. * Error output using `--no-interleaved-output` no longer prepends indenting whitespace. This allows emacs compilation-mode and vim quickfix to locate and track errors. See [#5523](https://github.com/commercialhaskell/stack/pull/5523) Bug fixes: * `stack new` now supports branches other than `master` as default for GitHub repositories. See [#5422](https://github.com/commercialhaskell/stack/issues/5422) * Ignore all errors from `hi-file-parser`. See [#5445](https://github.com/commercialhaskell/stack/issues/5445) and [#5486](https://github.com/commercialhaskell/stack/issues/5486). * Support basic auth in package-indices. See [#5509](https://github.com/commercialhaskell/stack/issues/5509). * Add support for parsing `.hi`. files from GHC 8.10 and 9.0. See [hi-file-parser#2](https://github.com/commercialhaskell/hi-file-parser/pull/2). ## v2.5.1.1 - 2020-12-09 Hackage-only release: * Support build with persistent-2.11.x and optparse-applicative-0.16.x ## v2.5.1 - 2020-10-15 **Changes since v2.3.3** Major changes: * Add the `snapshot-location-base` yaml configuration option, which allows to override the default location of snapshot configuration files. This option affects how snapshot synonyms (LTS/Nightly) are expanded to URLs by the `pantry` library. * `docker-network` configuration key added to override docker `--net` arg Behavior changes: * File watching now takes into account specified targets, old behavior could be restored using the new flag `--watch-all` [#5310](https://github.com/commercialhaskell/stack/issues/5310) Other enhancements: * The output of `stack ls dependencies json` now includes keys `sha256` and `size` for dependencies of `type` `archive` in `location`. [#5280](https://github.com/commercialhaskell/stack/issues/5280) * Build failures now show a hint to scroll up to the corresponding section [#5279](https://github.com/commercialhaskell/stack/issues/5279) * Customisable output styles (see `stack --help` and the `--stack-colors` option, and `stack ls stack-colors --help`) now include `info`, `debug`, `other-level`, `secondary` and `highlight`, used with verbose output. Bug fixes: * Fix `stack test --coverage` when using Cabal 3 * `stack new` now generates PascalCase'd module name correctly. [#5376](https://github.com/commercialhaskell/stack/issues/5376) * Connection issues to Casa server no longer cause builds to failure. Casa acts only as an optimizing cache layer, not a critical piece of infrastructure. * Fix modified time busting caches by always calculating sha256 digest during the build process. [#5125](https://github.com/commercialhaskell/stack/issues/5125) ## v2.3.3 - 2020-08-06 **Changes since v2.3.1** Other enhancements: * Add the `stack-developer-mode` flag Bug fixes: * When using the `STACK_YAML` env var with Docker, make the path absolute. * Fix the problem of `stack repl foo:test:bar` failing without a project build before that. See [#5213](https://github.com/commercialhaskell/stack/issues/5213) * Fix `stack sdist` introducing unnecessary sublibrary syntax when using pvp-bounds. See [#5289](https://github.com/commercialhaskell/stack/issues/5289) ## v2.3.1 - 2020-04-29 Release notes: * We have reduced the number of platforms that we support with executable releases. The reason behind this is that we've been slowed down in our release process until now with issues trying to build executables for less common platforms. In order to make sure we can address issues more quickly (like supporting new GHC versions), we're limiting support from the Stack team to: * Linux 64-bit/x86_64 (statically-linked) * macOS x86_64 * Windows 64-bit/x86_64 If others want to provide additional executables, we will definitely be happy for the support. But since our CI system is currently able to produce these three executables only, that's what we will be providing with the next release. * Since we no longer have dynamically-linked Linux executables, we are removing the `-static` suffix from the static Linux/x86_64 executables. If you have scripts to download the latest stable Linux/x86_64 executable, update them to use `linux-x86_64` instead of `linux-x86_64-static` (if you are already using the former, nothing needs to change). For this release, both are supported, but the next release will no longer have the `-static` variant. * We are also deprecating the download links at https://stackage.org/stack. See this page for the current installation instructions: https://docs.haskellstack.org/en/stable/install_and_upgrade/. * These are the canonical locations to download the latest stable binaries from, and will continue to be supported going forward: * Linux 64-bit/x86_64 (static): https://get.haskellstack.org/stable/linux-x86_64.tar.gz * macOS x86_64: https://get.haskellstack.org/stable/osx-x86_64.tar.gz * Windows 64-bit/x86_64: https://get.haskellstack.org/stable/windows-x86_64.zip As always, binaries for specific versions are available from the GitHub releases: https://github.com/commercialhaskell/stack/releases. **Changes since v2.1.3.1** Major changes: * `setup-info-locations` yaml configuration now allows overwriting the default locations of `stack-setup-2.yaml`. [#5031](https://github.com/commercialhaskell/stack/pull/5031) [#2983](https://github.com/commercialhaskell/stack/issues/2983) [#2913](https://github.com/commercialhaskell/stack/issues/2913) * The `setup-info` configuration key now allows overwriting parts of the default `setup-info` * The `--setup-info-yaml` command line flag now may be used in all Stack commands such as `stack build`, and not only in `stack setup` * The `--setup-info-yaml` may specify multiple locations for `stack-setup.yaml` files. * The `stack upload` can read first reads environment Variable `$HACKAGE_USERNAME` and `$HACKAGE_PASSWORD` if they are missing only then asks for `username` or `password` * Fully remove GHCJS support. * Remove the `freeze` command. It has been replaced by lock files. Behavior changes: * Remove the deprecated `--stack-setup-yaml` command line argument in favor of `--setup-info-yaml`. See [#2647](https://github.com/commercialhaskell/stack/issues/2647) * We now recommend checking in generated Cabal files for repos. When generating lock files for extra-deps that only include `package.yaml` files, a deprecation warning will be generated. Also, those packages will no longer be included in the generated lock files. See [#5210](https://github.com/commercialhaskell/stack/issues/5210). Other enhancements: * Add `build-output-timestamps` flag in yaml. Setting it to true prefixes each build log output line with a timestamp. * Show warning about `local-programs-path` with spaces on windows when running scripts. See [#5013](https://github.com/commercialhaskell/stack/pull/5013) * Add `ls dependencies json` which will print dependencies as JSON. `ls dependencies --tree` is now `ls dependencies tree`. See [#4424](https://github.com/commercialhaskell/stack/pull/4424) * Remove warning for using Stack with GHC 8.8-8.10, and Cabal 3.0-3.2. * Allow relative paths in `--setup-info-yaml` and tool paths [#3394](https://github.com/commercialhaskell/stack/issues/3394) * Added the `--only-locals` flag. See [#5272](https://github.com/commercialhaskell/stack/issues/5272) Bug fixes: * Upgrade `pantry`: module mapping insertions into the database are now atomic. Previously, if you SIGTERMed at the wrong time while running a script, you could end up with an inconsistent database state. * `--resolver global` doesn't retrieve snapshots list from the internet because doesn't need it. See [#5103](https://github.com/commercialhaskell/stack/issues/5103) * Fix using relative links in haddocks output. See [#4971](https://github.com/commercialhaskell/stack/issues/4971). * Do not include generated Cabal file information in lock files. See [#5045](https://github.com/commercialhaskell/stack/issues/5045). * Use proper Hoogle executable path when installed automatically. See [#4905](https://github.com/commercialhaskell/stack/issues/4905) * Fix GHC version for batched package unregistration. See [#4951](https://github.com/commercialhaskell/stack/issues/4951) * Use Hoogle from the snapshot used and not the latest version. See [#4905](https://github.com/commercialhaskell/stack/issues/4905) * Resolve "'stty' is not recognized". See [#4901](https://github.com/commercialhaskell/stack/issues/4901) * Fix missing reconfigure check causing errors when a package gets used in multiple projects. See [#5147](https://github.com/commercialhaskell/stack/issues/5147) ## v2.1.3.1 - 2019-07-16 Hackage-only release: * Support persistent-template-2.7.x * Support rio-0.1.11.0 * Add `stack.yaml` back to hackage sdist, and add `snapshot.yaml` ## v2.1.3 - 2019-07-13 **Changes since v2.1.1** Behavior changes: * Disable WAL mode for SQLite3 databases, to improve compatibility with some platforms and filesystems. See [#4876](https://github.com/commercialhaskell/stack/issues/4876). * By default, do not perform expiry checks in Hackage Security. See [#4928](https://github.com/commercialhaskell/stack/issues/4928). Other enhancements: * Do not rerun expected test failures. This is mostly a change that will only affect the Stackage Curator use case, but there is now an additional message letting the user know when a previously-failed test case is being rerun. * Move configure information for project packages back to .stack-work to improve caching. See [#4893](https://github.com/commercialhaskell/stack/issues/4893). Bug fixes: * Fix to allow dependencies on specific versions of local git repositories. See [#4862](https://github.com/commercialhaskell/stack/pull/4862) * Allow Stack commands to be run in Nix mode without having a project file available. See [#4854](https://github.com/commercialhaskell/stack/issues/4864). * Removes dependency on gnu-tar for OSX and Linux environment. The `--force-local` option was required only for windows environment. * Properly wait for the `tar` subprocess to complete before returning, thereby avoiding a SIGTERM screwing up GHC installation. See [#4888](https://github.com/commercialhaskell/stack/issues/4888). * Use package complete locations from lock files when resolving dependencies in `extra-deps`. See [#4887](https://github.com/commercialhaskell/stack/issues/4887). * Set the `HASKELL_DIST_DIR` environment to a proper package dist directory so `doctest` is able to load modules autogenerated by Cabal. * Expose package library when running tests. * Fix support for non-ASCII module names. See [#4938](https://github.com/commercialhaskell/stack/issues/4938) Other changes: * Rename `pantry-tmp` package back to `pantry`, now that we have gained maintainership (which had been used by someone else for a candidate-only test that made it look like the name was free but prevented uploading a real package). ## v2.1.1.1 - 2019-06-14 Hackage-only release that removes `stack.yaml` from the sdist. This is because `stack.yaml` now defines a multi-package project, whereas Hackage works on the basis on individual packages (see [#4860](https://github.com/commercialhaskell/stack/issues/4860)) If building a `stack` executable for distribution, please download the source code from https://github.com/commercialhaskell/stack/releases/tag/v2.1.1 and build it using Stack itself in order to ensure identical behaviour to official binaries. This package on Hackage is provided for convenience and bootstrapping purposes. ## v2.1.1 - 2019-06-13 The Stack 2 release represents a series of significant changes to how Stack works internally. For the vast majority of cases, these changes are backwards compatible, in that existing projects will continue to build in the same way with Stack 2 as they did with Stack 1. The large version bump is due to the fundamental internal changes to cache handling, database storage (using SQLite in place of binary files), implicit snapshots (which greatly improve the precompiled cache), and moving to Pantry. We have also removed some less used features, as listed below. **Changes since v1.9.3** Major changes: * Switch over to pantry for managing packages. This is a major change to Stack's internals, and affects user-visible behavior in a few places. Some highlights: * Drop support for multiple package indices and legacy `00-index.tar` style indices. See [#4137](https://github.com/commercialhaskell/stack/issues/4137). * Support for archives and repos in values of the `packages` key has been removed. Instead, you must use the `extra-deps` key for such dependencies. `packages` now only supports local filepaths. * Add support for Git repositories containing (recursive) submodules. * Addition of new configuration options for specifying a "pantry tree" key, which provides more reproducibility around builds, and (in the future) will be used for more efficient package content downloads. You can also specify package name and version for more efficient config parsing. * __NOTE__ The new `stack freeze` command provides support for automatically generating this additional information. * Package contents and metadata are stored in an SQLite database in place of files on the filesystem. The `pantry` library can be used for interacting with these contents. * Internally, Stack has changed many datatypes, including moving to Cabal's definition of many data types. As a result of such changes, existing cache files will in general be invalidated, resulting in Stack needing to rebuild many previously cached builds in the new version. Sorry :(. * A new command, `stack freeze` has been added which outputs project and snapshot definitions with dependencies pinned to their exact versions. * The `ignore-revision-mismatch` setting is no longer needed, and has been removed. * Overriding GHC boot packages results in any other GHC boot packages depending on it being no longer available as a dependency, such packages need to be added explicitly when needed. See [#4510] (https://github.com/commercialhaskell/stack/issues/4510). * Cabal solver integration was not updated to support newer `cabal-install` versions so `stack solver` command was removed as well as a related option `--solver` from `stack new` and `stack init`. * Upgrade to Cabal 2.4 * Note that, in this process, the behavior of file globbing has been modified to match that of Cabal. In particular, this means that for Cabal spec versions less than 2.4, `*.txt` will match `foo.txt`, but not `foo.2.txt`. * Remove the `stack image` command. With the advent of Docker multistage builds, this functionality is no longer useful. For an example, please see [Building Haskell Apps with Docker](https://www.fpcomplete.com/blog/2017/12/building-haskell-apps-with-docker). * Experimental: Support building GHC from source * Stack now supports building and installing GHC from source. The built GHC is uniquely identified by a commit id and an Hadrian "flavour" (Hadrian is the newer GHC build system), hence `compiler` can be set to use a GHC built from source with `ghc-git-COMMIT-FLAVOUR` * `stack.yaml` now supports a `configure-options`, which are passed directly to the `configure` step in the Cabal build process. See [#1438](https://github.com/commercialhaskell/stack/issues/1438) * Remove support for building GHCJS itself. Future releases of Stack may remove GHCJS support entirely. * Support for lock files for pinning exact project dependency versions Behavior changes: * `stack.yaml` now supports `snapshot`: a synonym for `resolver`. See [#4256](https://github.com/commercialhaskell/stack/issues/4256) * `stack script` now passes `-i -idir` in to the `ghc` invocation. This makes it so that the script can import local modules, and fixes an issue where `.hs` files in the current directory could affect interpretation of the script. See [#4538](https://github.com/commercialhaskell/stack/pull/4538) * When using `stack script`, custom snapshot files will be resolved relative to the directory containing the script. * Remove the deprecated `--upgrade-cabal` flag to `stack setup`. * Support the `drop-packages` key in `stack.yaml` * Remove the GPG signing code during uploads. The GPG signatures have never been used yet, and there are no plans to implement signature verification. * Remove the `--plain` option for the `exec` family of commands * Always use the `--exact-configuration` Cabal configuration option when building (should mostly be a non-user-visible enhancement). * No longer supports Cabal versions older than `1.19.2`. This means projects using snapshots earlier than `lts-3.0` or `nightly-2015-05-05` will no longer build. * Remove the `stack docker cleanup` command. Docker itself now has [`docker image prune`](https://docs.docker.com/engine/reference/commandline/image_prune/) and [`docker container prune`](https://docs.docker.com/engine/reference/commandline/container_prune/), which you can use instead. * Interleaved output is now turned on by default, see [#4702](https://github.com/commercialhaskell/stack/issues/4702). In addition, the `packagename> ` prefix is no longer included in interleaved mode when only building a single target. * The `-fhide-source-paths` GHC option is now enabled by default and can be disabled via the `hide-source-paths` configuration option in `stack.yaml`. See [#3784](https://github.com/commercialhaskell/stack/issues/3784) * Stack will reconfigure a package if you modify your `PATH` environment variable. See [#3138](https://github.com/commercialhaskell/stack/issues/3138). * For GHC 8.4 and later, disable the "shadowed dependencies" workaround. This means that Stack will no longer have to force reconfigures as often. See [#3554](https://github.com/commercialhaskell/stack/issues/3554). * When building a package, Stack takes a lock on the dist directory in use to avoid multiple runs of Stack from trampling each others' files. See [#2730](https://github.com/commercialhaskell/stack/issues/2730). * Stack will check occasionally if there is a new version available and prompt the user to upgrade. This will not incur any additional network traffic, as it will piggy-back on the existing Hackage index updates. You can set `recommend-stack-upgrade: false` to bypass this. See [#1681](https://github.com/commercialhaskell/stack/issues/1681). * `stack list-dependencies` has been removed in favour of `stack ls dependencies`. * The new default for `--docker-auto-pull` is enabled. See [#3332](https://github.com/commercialhaskell/stack/issues/3332). Other enhancements: * Support MX Linux in get-stack.sh. Fixes [#4769](https://github.com/commercialhaskell/stack/issues/4769). * Defer loading up of files for project packages. This allows us to get plan construction errors much faster, and avoid some unnecessary work when only building a subset of packages. This is especially useful for the curator use case. * Existing global option `--color=WHEN` is now also available as a non-project-specific yaml configuration parameter `color:`. * Adopt the standard proposed at http://no-color.org/, that color should not be added by default if the `NO_COLOR` environment variable is present. * New command `stack ls stack-colors` lists the styles and the associated 'ANSI' control character sequences that Stack uses to color some of its output. See `stack ls stack-colors --help` for more information. * New global option `--stack-colors=STYLES`, also available as a non-project-specific yaml configuration parameter, allows a Stack user to redefine the default styles that Stack uses to color some of its output. See `stack --help` for more information. * British English spelling of 'color' (colour) accepted as an alias for `--color`, `--stack-colors`, `stack ls stack-colors` at the command line and for `color:` and `stack-colors:` in yaml configuration files. * New build option `--ddump-dir`. (See [#4225](https://github.com/commercialhaskell/stack/issues/4225)) * Stack parses and respects the `preferred-versions` information from Hackage for choosing latest version of a package in some cases, e.g. `stack unpack packagename`. * The components output in the `The main module to load is ambiguous` message now include package names so they can be more easily copy-pasted. * Git repos are shared across multiple projects. See [#3551](https://github.com/commercialhaskell/stack/issues/3551) * Use en_US.UTF-8 locale by default in pure Nix mode so programs won't crash because of Unicode in their output [#4095](https://github.com/commercialhaskell/stack/issues/4095) * Add `--tree` to `ls dependencies` to list dependencies as tree. [#4101](https://github.com/commercialhaskell/stack/issues/4101) * Add `--pedantic` to `ghci` to run with `-Wall` and `-Werror` [#4463](https://github.com/commercialhaskell/stack/issues/4463) * Add `--cabal-files` flag to `stack ide targets` command. * Add `--stdout` flag to all `stack ide` subcommands. * Use batches when unregistering packages with `ghc-pkg`. (See [#2662](https://github.com/commercialhaskell/stack/issues/2662)) * `get-stack` script now works on Windows CI machines of Appveyor, Travis and Azure Pipelines. See [#4535](https://github.com/commercialhaskell/stack/issues/4535)/ * Show snapshot being used when `stack ghci` is invoked outside of a project directory. See [#3651](https://github.com/commercialhaskell/stack/issues/3651) * The script interpreter now accepts a `--extra-dep` flag for adding packages not present in the snapshot. Currently, this only works with packages from Hackage, not Git repos or archives. * When using the script interpreter with `--optimize` or `--compile`, Stack will perform an optimization of checking whether a newer executable exists, making reruns significantly faster. There's a downside to this, however: if you have a multifile script, and change one of the dependency modules, Stack will not automatically detect and recompile. * `stack clean` will delete the entire `.stack-work/dist` directory, not just the relevant subdirectory for the current GHC version. See [#4480](https://github.com/commercialhaskell/stack/issues/4480). * Add `stack purge` as a shortcut for `stack clean --full`. See [#3863](https://github.com/commercialhaskell/stack/issues/3863). * Both `stack dot` and `stack ls dependencies` accept a `--global-hints` flag to bypass the need for an installed GHC. See [#4390](https://github.com/commercialhaskell/stack/issues/4390). * Add the `stack config env` command for getting shell script environment variables. See [#620](https://github.com/commercialhaskell/stack/issues/620). * Less verbose output from `stack setup` on Windows. See [#1212](https://github.com/commercialhaskell/stack/issues/1212). * Add an optional `ignore-expiry` key to the `hackage-security` key of `~/.stack/config.yaml`. It allows disabling of timestamp expiration verification just like `cabal --ignore-expiry` does. The flag is not enabled by default so that the default functionality is not changed. * Include default values for most command line flags in the `--help` output. See [#893](https://github.com/commercialhaskell/stack/issues/893). * Set the `GHC_ENVIRONMENT` environment variable to specify dependency packages explicitly when running test. This is done to prevent ambiguous module name errors in `doctest` tests. * `get-stack` script now works on Windows CI machines of Appveyor, Travis and Azure Pipelines. See [#4535](https://github.com/commercialhaskell/stack/issues/4535) * Warn when a Docker image does not include a `PATH` environment variable. See [#2472](https://github.com/commercialhaskell/stack/issues/2742) * When using `system-ghc: true`, Stack will now find the appropriate GHC installation based on the version suffix, allowing you to more easily switch between various system-installed GHCs. See [#2433](https://github.com/commercialhaskell/stack/issues/2433). * `stack init` will now support create a `stack.yaml` file without any local packages. See [#2465](https://github.com/commercialhaskell/stack/issues/2465) * Store caches in SQLite database instead of files. * No longer use "global" Docker image database (`docker.db`). * User config files are respected for the script command. See [#3705](https://github.com/commercialhaskell/stack/issues/3705), [#3887](https://github.com/commercialhaskell/stack/issues/3887). * Set the `GHC_ENVIRONMENT` environment variable to `-` to tell GHC to ignore any such files when GHC is new enough (>= 8.4.4), otherwise simply unset the variable. This allows Stack to have control of package databases when running commands like `stack exec ghci`, even in the presence of implicit environment files created by `cabal new-build`. See [#4706](https://github.com/commercialhaskell/stack/issues/4706). * Use a database cache table to speed up discovery of installed GHCs * You can specify multiple `--test-arguments` options. See [#2226](https://github.com/commercialhaskell/stack/issues/2226) * Windows terminal width detection is now done. See [#3588](https://github.com/commercialhaskell/stack/issues/3588) * On Windows, informs users if the 'programs' path contains a space character and further warns users if that path does not have an alternative short ('8 dot 3') name, referencing the `local-programs-path` configuration option. See [#4726](https://github.com/commercialhaskell/stack/issues/4726) * Add `--docker-mount-mode` option to set the Docker volume mount mode for performance tuning on macOS. Bug fixes: * Ignore duplicate files for a single module when a Haskell module was generated from a preprocessor file. See [#4076](https://github.com/commercialhaskell/stack/issues/4076). * Only track down components in current directory if there are no hs-source-dirs found. This eliminates a number of false-positive warnings, similar to [#4076](https://github.com/commercialhaskell/stack/issues/4076). * Handle a change in GHC's hi-dump format around `addDependentFile`, which now includes a hash. See [yesodweb/yesod#1551](https://github.com/yesodweb/yesod/issues/1551) * Fix `subdirs` for git repos in `extra-deps` to match whole directory names. Also fixes for `subdirs: .`. See [#4292](https://github.com/commercialhaskell/stack/issues/4292) * Fix for git packages to update submodules to the correct state. See [#4314](https://github.com/commercialhaskell/stack/pull/4314) * Add `--cabal-files` flag to `stack ide targets` command. * Don't download ghc when using `stack clean`. * Support loading in GHCi definitions from symlinked C files. Without this patch, Stack will try to find object files in the directory pointed to by symlinks, while GCC will produce the object files in the original directory. See [#4402](https://github.com/commercialhaskell/stack/pull/4402) * Fix handling of GitHub and URL templates on Windows. See [#4394](https://github.com/commercialhaskell/stack/issues/4394) * Fix `--file-watch` not responding to file modifications when running inside docker on Mac. See [#4506](https://github.com/commercialhaskell/stack/issues/4506) * Using `--ghc-options` with `stack script --compile` now works. * Ensure the detailed-0.9 type tests work. See [#4453](https://github.com/commercialhaskell/stack/issues/4453). * Extra include and lib dirs are now order-dependent. See [#4527](https://github.com/commercialhaskell/stack/issues/4527). * Apply GHC options when building a `Setup.hs` file. See [#4526](https://github.com/commercialhaskell/stack/issues/4526). * Stack handles ABI changes in FreeBSD 12 by differentiating that version from previous. * Help text for the `templates` subcommand now reflects behaviour in Stack 1.9 — that it downloads and shows a help file, rather than listing available templates. * Fix detection of AArch64 platform (this broke when we upgraded to a newer Cabal version). * Docker: fix detecting and pulling missing images with `--docker-auto-pull`. See [#4598](https://github.com/commercialhaskell/stack/issues/4598) * Hackage credentials are not world-readable. See [#2159](https://github.com/commercialhaskell/stack/issues/2159). * Warnings are dumped from logs even when color is enabled. See [#2997](https://github.com/commercialhaskell/stack/issues/2997) * `stack init` will now work for Cabal files with sublibraries. See [#4408](https://github.com/commercialhaskell/stack/issues/4408) * When the Cabal spec version is newer than the global Cabal version, build against the snapshot's Cabal library. See [#4488](https://github.com/commercialhaskell/stack/issues/4488) * Docker: fix detection of expected subprocess failures. This fixes downloading a compatible `stack` executable when the host `stack` is not compatible with the Docker image (on Linux), and doesn't show an unnecessary extra error when the in-container re-exec'ed `stack` exits with failure. * The `stack ghci` command's `--ghc-options` flag now parses multiple options. See [#3315](https://github.com/commercialhaskell/stack/issues/3315). ## v1.9.3.1 - 2019-04-18 Hackage-only release with no user facing changes (added compatibility with `rio-0.1.9.2`). ## v1.9.3 - 2018-12-02 Bug fixes: * Stack can now be compiled again inside a directory that does not contain a `.git` directory. See [#4364](https://github.com/commercialhaskell/stack/issues/4364#issuecomment-431600841) * Handle a change in GHC's hi-dump format around `addDependentFile`, which now includes a hash. See [yesodweb/yesod#1551](https://github.com/yesodweb/yesod/issues/1551) * Allow variables to appear in template file names. ## v1.9.1.1 - 2018-11-14 Hackage-only release with no user facing changes. * Stack can now be compiled again inside a directory that does not contain a `.git` directory. See [#4364](https://github.com/commercialhaskell/stack/issues/4364#issuecomment-431600841) ## v1.9.1 - 2018-10-17 Release notes: * Statically-linked Linux executables are back again, thanks to [@nh2](https://github.com/nh2). * We will be deleting the Ubuntu, Debian, CentOS, Fedora, and Arch package repos from `download.fpcomplete.com` soon. These have been deprecated for over a year and have not received new releases, but were left in place for compatibility with older scripts. Major changes: * Upgrade to Cabal 2.4 * Note that, in this process, the behavior of file globbing has been modified to match that of Cabal. In particular, this means that for Cabal spec versions less than 2.4, `*.txt` will match `foo.txt`, but not `foo.2.txt`. * `GHCJS` support is being downgraded to 'experimental'. A warning notifying the user of the experimental status of `GHCJS` will be displayed. Behavior changes: * `ghc-options` from `stack.yaml` are now appended to `ghc-options` from `config.yaml`, whereas before they would be replaced. * `stack build` will now announce when sublibraries of a package are being build, in the same way executables, tests, benchmarks and libraries are announced * `stack sdist` will now announce the destination of the generated tarball, regardless of whether or not it passed the sanity checks * The `--upgrade-cabal` option to `stack setup` has been deprecated. This feature no longer works with GHC 8.2 and later. Furthermore, the reason for this flag originally being implemented was drastically lessened once Stack started using the snapshot's `Cabal` library for custom setups. See: [#4070](https://github.com/commercialhaskell/stack/issues/4070). * With the new namespaced template feature, `stack templates` is no longer able to meaningfully display a list of all templates available. Instead, the command will download and display a [help file](https://github.com/commercialhaskell/stack-templates/blob/master/STACK_HELP.md) with more information on how to discover templates. See: [#4039](https://github.com/commercialhaskell/stack/issues/4039) * Tools used during building ('build tools') are now handled in a similar way to `cabal-install`. In particular, for legacy `build-tools` fields, we use a hard-coded list of build tools in place of looking up build tool packages in a tool map. This both brings Stack's behavior closer into line with `cabal-install`, avoids some bugs, and opens up some possible optimizations/laziness. See: [#4125](https://github.com/commercialhaskell/stack/issues/4125). * Mustache templating is not applied to large files (over 50kb) to avoid performance degradation. See: [#4133](https://github.com/commercialhaskell/stack/issues/4133). * `stack upload` signs the package by default, as documented. `--no-signature` turns the signing off. [#3739](https://github.com/commercialhaskell/stack/issues/3739) * In case there is a network connectivity issue while trying to download a template, Stack will check whether that template had been downloaded before. In that case, the cached version will be used. See [#3850](https://github.com/commercialhaskell/stack/issues/3850). * In Stack's script interpreter, `-- stack --verbosity=info script` and `-- stack script --verbosity=info` now have the same effect and both override the `--verbosity=error` default in the interpreter. Previously the default meant the former was equivalent to `-- stack --verbosity=info script --verbosity=error` and the latter was equivalent to `-- stack --verbosity=error script --verbosity=info`, with the subcommand's global option having precedence over the Stack command's global option in each case. See [#5326](https://github.com/commercialhaskell/stack/issues/5326). Other enhancements: * On Windows before Windows 10, --color=never is the default on terminals that can support ANSI color codes in output only by emulation * On Windows, recognise a 'mintty' (false) terminal as a terminal, by default * `stack build` issues a warning when `base` is explicitly listed in `extra-deps` of `stack.yaml` * `stack build` suggests trying another GHC version should the build plan end up requiring unattainable `base` version. * A new sub command `run` has been introduced to build and run a specified executable similar to `cabal run`. If no executable is provided as the first argument, it defaults to the first available executable in the project. * `stack build` missing dependency suggestions (on failure to construct a valid build plan because of missing deps) are now printed with their latest Cabal file revision hash. See [#4068](https://github.com/commercialhaskell/stack/pull/4068). * Added new `--tar-dir` option to `stack sdist`, that allows to copy the resulting tarball to the specified directory. * Introduced the `--interleaved-output` command line option and `build.interleaved-output` config value which causes multiple concurrent builds to dump to stderr at the same time with a `packagename> ` prefix. See [#3225](https://github.com/commercialhaskell/stack/issues/3225). * The default retry strategy has changed to exponential backoff. This should help with [#3510](https://github.com/commercialhaskell/stack/issues/3510). * `stack new` now allows template names of the form `username/foo` to download from a user other than `commercialstack` on GitHub, and can be prefixed with the service `github:`, `gitlab:`, or `bitbucket:`. See [#4039](https://github.com/commercialhaskell/stack/issues/4039) * Switch to `githash` to include some unmerged bugfixes in `gitrev` Suggestion to add `'allow-newer': true` now shows path to user config file where this flag should be put into [#3685](https://github.com/commercialhaskell/stack/issues/3685) * `stack ghci` now asks which main target to load before doing the build, rather than after * Bump to Hpack 0.29.0 * With GHC 8.4 and later, Haddock is given the `--quickjump` flag. * It is possible to specify the Hackage base URL to upload packages to, instead of the default of `https://hackage.haskell.org/`, by using `hackage-base-url` configuration option. * When using Nix, if a specific minor version of GHC is not requested, the latest minor version in the given major branch will be used automatically. Bug fixes: * `stack ghci` now does not invalidate `.o` files on repeated runs, meaning any modules compiled with `-fobject-code` will be cached between ghci runs. See [#4038](https://github.com/commercialhaskell/stack/pull/4038). * `~/.stack/config.yaml` and `stack.yaml` terminating by newline * The previous released caused a regression where some `stderr` from the `ghc-pkg` command showed up in the terminal. This output is now silenced. * A regression in recompilation checking introduced in v1.7.1 has been fixed. See [#4001](https://github.com/commercialhaskell/stack/issues/4001) * `stack ghci` on a package with internal libraries was erroneously looking for a wrong package corresponding to the internal library and failing to load any module. This has been fixed now and changes to the code in the library and the sublibrary are properly tracked. See [#3926](https://github.com/commercialhaskell/stack/issues/3926). * For packages with internal libraries not depended upon, `stack build` used to fail the build process since the internal library was not built but it was tried to be registered. This is now fixed by always building internal libraries. See [#3996](https://github.com/commercialhaskell/stack/issues/3996). * `--no-nix` was not respected under NixOS * Fix a regression which might use a lot of RAM. See [#4027](https://github.com/commercialhaskell/stack/issues/4027). * Order of commandline arguments does not matter anymore. See [#3959](https://github.com/commercialhaskell/stack/issues/3959) * When prompting users about saving their Hackage credentials on upload, flush to stdout before waiting for the response so the prompt actually displays. Also fixes a similar issue with ghci target selection prompt. * If `cabal` is not on PATH, running `stack solver` now prompts the user to run `stack install cabal-install` * `stack build` now succeeds in building packages which contain sublibraries which are dependencies of executables, tests or benchmarks but not of the main library. See [#3787](https://github.com/commercialhaskell/stack/issues/3787). * Sublibraries are now properly considered for coverage reports when the test suite depends on the internal library. Before, Stack was erroring when trying to generate the coverage report, see [#4105](https://github.com/commercialhaskell/stack/issues/4105). * Sublibraries are now added to the precompiled cache and recovered from there when the snapshot gets updated. Previously, updating the snapshot when there was a package with a sublibrary in the snapshot resulted in broken builds. This is now fixed, see [#4071](https://github.com/commercialhaskell/stack/issues/4071). * [#4114](https://github.com/commercialhaskell/stack/issues/4114) Stack pretty prints error messages with proper `error` logging level instead of `warning` now. This also fixes self-executing scripts not piping plan construction errors from runhaskell to terminal (issue [#3942](https://github.com/commercialhaskell/stack/issues/3942)). * Fix invalid "While building Setup.hs" when Cabal calls fail. See: [#3934](https://github.com/commercialhaskell/stack/issues/3934) * `stack upload` signs the package by default, as documented. `--no-signature` turns the signing off. [#3739](https://github.com/commercialhaskell/stack/issues/3739) ## v1.7.1 - 2018-04-27 Release notes: * AArch64 (64-bit ARM) executables are now available for the first time. * Statically-linked Linux executables are no longer available, due to difficulty with GHC 8.2.2 on Alpine Linux. * 32-bit Linux GMP4 executables for CentOS 6 are no longer available, since GHC 8.2.2 is no longer being built for that platform. Major changes: * Upgrade from Cabal 2.0 to Cabal 2.2 Behavior changes: * `stack setup` no longer uses different GHC configure options on Linux distributions that use GCC with PIE enabled by default. GHC detects this itself since ghc-8.0.2, and Stack's attempted workaround for older versions caused more problems than it solved. * `stack new` no longer initializes a project if the project template contains a `stack.yaml` file. Other enhancements: * A new sub command `ls` has been introduced to Stack to view local and remote snapshots present in the system. Use `stack ls snapshots --help` to get more details about it. * `list-dependencies` has been deprecated. The functionality has to accessed through the new `ls dependencies` interface. See [#3669](https://github.com/commercialhaskell/stack/issues/3669) for details. * Specify User-Agent HTTP request header on every HTTP request. See [#3628](https://github.com/commercialhaskell/stack/issues/3628) for details. * `stack setup` looks for GHC binary distributions and installations by any OS key that is compatible (rather than only checking a single one). This is relevant on Linux where different distributions may have different combinations of libtinfo 5/6, ncurses 5/6, and gmp 4/5, and will allow simplifying the setup-info metadata YAML for future GHC releases. * The build progress bar reports names of packages currently building. * `stack setup --verbose` causes verbose output of GHC configure process. See [#3716](https://github.com/commercialhaskell/stack/issues/3716) * Improve the error message when an `extra-dep` from a path or git reference can't be found. See [#3808](https://github.com/commercialhaskell/stack/pull/3808) * Nix integration is now disabled on windows even if explicitly enabled, since it isn't supported. See [#3600](https://github.com/commercialhaskell/stack/issues/3600) * `stack build` now supports a new flag `--keep-tmp-files` to retain intermediate files and directories for the purpose of debugging. It is best used with ghc's equivalent flag, i.e. `stack build --keep-tmp-files --ghc-options=-keep-tmp-files`. See [#3857](https://github.com/commercialhaskell/stack/issues/3857) * Improved error messages for snapshot parse exceptions * `stack unpack` now supports a `--to /target/directory` option to specify where to unpack the package into * `stack hoogle` now supports a new flag `--server` that launches local Hoogle server on port 8080. See [#2310](https://github.com/commercialhaskell/stack/issues/2310) Bug fixes: * The script interpreter's implicit file arguments are now passed before other arguments. See [#3658](https://github.com/commercialhaskell/stack/issues/3658). In particular, this makes it possible to pass `-- +RTS ... -RTS` to specify RTS arguments used when running the script. * Don't ignore the template `year` parameter in config files, and clarify the surrounding documentation. See [#2275](https://github.com/commercialhaskell/stack/issues/2275). * Benchmarks used to be run concurrently with other benchmarks and build steps. This is non-ideal because CPU usage of other processes may interfere with benchmarks. It also prevented benchmark output from being displayed by default. This is now fixed. See [#3663](https://github.com/commercialhaskell/stack/issues/3663). * `stack ghci` now allows loading multiple packages with the same module name, as long as they have the same filepath. See [#3776](https://github.com/commercialhaskell/stack/pull/3776). * `stack ghci` no longer always adds a dependency on `base`. It is now only added when there are no local targets. This allows it to be to load code that uses replacements for `base`. See [#3589](https://github.com/commercialhaskell/stack/issues/3589#issuecomment) * `stack ghci` now uses correct paths for autogen files with [#3791](https://github.com/commercialhaskell/stack/issues/3791) * When a package contained sublibraries, Stack was always recompiling the package. This has been fixed now, no recompilation is being done because of sublibraries. See [#3899](https://github.com/commercialhaskell/stack/issues/3899). * The `get-stack.sh` install script now matches manual instructions when it comes to Debian/Fedora/CentOS install dependencies. * Compile Cabal-simple with gmp when using Nix. See [#2944](https://github.com/commercialhaskell/stack/issues/2944) * `stack ghci` now replaces the Stack process with ghci. This improves signal handling behavior. In particular, handling of Ctrl-C. To make this possible, the generated files are now left behind after exit. The paths are based on hashing file contents, and it's stored in the system temporary directory, so this shouldn't result in too much garbage. See [#3821](https://github.com/commercialhaskell/stack/issues/3821). ## v1.6.5 - 2018-02-19 Bug fixes: * Some unnecessary rebuilds when no files were changed are now avoided, by having a separate build cache for each component of a package. See [#3732](https://github.com/commercialhaskell/stack/issues/3732). * Correct the behavior of promoting a package from snapshot to local package. This would get triggered when version bounds conflicted in a snapshot, which could be triggered via Hackage revisions for old packages. This also should allow custom snapshots to define conflicting versions of packages without issue. See [Stackage issue #3185](https://github.com/fpco/stackage/issues/3185). * When promoting packages from snapshot to local, we were occasionally discarding the actual package location content and instead defaulting to pulling the package from the index. We now correctly retain this information. Note that if you were affected by this bug, you will likely need to delete the binary build cache associated with the relevant custom snapshot. See [#3714](https://github.com/commercialhaskell/stack/issues/3714). * `--no-rerun-tests` has been fixed. Previously, after running a test we were forgetting to record the result, which meant that all tests always ran even if they had already passed before. See [#3770](https://github.com/commercialhaskell/stack/pull/3770). * Includes a patched version of `hackage-security` which fixes both some issues around asynchronous exception handling, and moves from directory locking to file locking, making the update mechanism resilient against SIGKILL and machine failure. See `hackage-security` issue [#187](https://github.com/haskell/hackage-security/issues/187) and Stack issue [#3073](https://github.com/commercialhaskell/stack/issues/3073). ## v1.6.3.1 - 2018-02-16 Hackage-only release with no user facing changes (updated to build with newer version of Hpack dependency). ## v1.6.3 - 2017-12-23 Enhancements: * In addition to supporting `.tar.gz` and `.zip` files as remote archives, plain `.tar` files are now accepted too. This will additionally help with cases where HTTP servers mistakenly set the transfer encoding to `gzip`. See [#3647](https://github.com/commercialhaskell/stack/issues/3647). * Links to docs.haskellstack.org ignore Stack version patchlevel. * Downloading Docker-compatible `stack` executable ignores Stack version patchlevel. Bug fixes: * For versions of Cabal before 1.24, ensure that the dependencies of non-buildable components are part of the build plan to work around an old Cabal bug. See [#3631](https://github.com/commercialhaskell/stack/issues/3631). * Run the Cabal file checking in the `sdist` command more reliably by allowing the Cabal library to flatten the `GenericPackageDescription` itself. ## v1.6.1.1 - 2017-12-20 Hackage-only release with no user facing changes (updated to build with newer dependency versions). ## v1.6.1 - 2017-12-07 Major changes: * Complete overhaul of how snapshots are defined, the `packages` and `extra-deps` keys, and a number of related items. For full details, please see the [writeup](https://www.fpcomplete.com/blog/2017/07/stacks-new-extensible-snapshots) on these changes. [PR #3249](https://github.com/commercialhaskell/stack/pull/3249), see the PR description for a number of related issues. * Upgraded to version 2.0 of the Cabal library. Behavior changes: * The `--install-ghc` flag is now on by default. For example, if you run `stack build` in a directory requiring a GHC that you do not currently have, Stack will automatically download and install that GHC. You can explicitly set `install-ghc: false` or pass the flag `--no-install-ghc` to regain the previous behavior. * `stack ghci` no longer loads modules grouped by package. This is always an improvement for plain ghci - it makes loading faster and less noisy. For intero, this has the side-effect that it will no longer load multiple packages that depend on TH loading relative paths. TH relative paths will still work when loading a single package into intero. See [#3309](https://github.com/commercialhaskell/stack/issues/3309) * Setting GHC options for a package via `ghc-options:` in your `stack.yaml` will promote it to a local package, providing for more consistency with flags and better reproducibility. See: [#849](https://github.com/commercialhaskell/stack/issues/849) * The `package-indices` setting with Hackage no longer works with the `00-index.tar.gz` tarball, but must use the `01-index.tar.gz` file to allow revised packages to be found. * Options passed via `--ghci-options` are now passed to the end of the invocation of ghci, instead of the middle. This allows using `+RTS` without an accompanying `-RTS`. * When auto-detecting `--ghc-build`, `tinfo6` is now preferred over `standard` if both versions of libtinfo are installed * Addition of `stack build --copy-compiler-tool`, to allow tools like intero to be installed globally for a particular compiler. [#2643](https://github.com/commercialhaskell/stack/issues/2643) * Stack will ask before saving hackage credentials to file. This new prompt can be avoided by using the `save-hackage-creds` setting. Please see [#2159](https://github.com/commercialhaskell/stack/issues/2159). * The `GHCRTS` environment variable will no longer be passed through to every program Stack runs. Instead, it will only be passed through commands like `exec`, `runghc`, `script`, `ghci`, etc. See [#3444](https://github.com/commercialhaskell/stack/issues/3444). * `ghc-options:` for specific packages will now come after the options specified for all packages / particular sets of packages. See [#3573](https://github.com/commercialhaskell/stack/issues/3573). * The `pvp-bounds` feature is no longer fully functional, due to some issues with the Cabal library's printer. See [#3550](https://github.com/commercialhaskell/stack/issues/3550). Other enhancements: * The `with-hpack` configuration option specifies an Hpack executable to use instead of the Hpack bundled with Stack. Please see [#3179](https://github.com/commercialhaskell/stack/issues/3179). * It's now possible to skip tests and benchmarks using `--skip` flag * `GitSHA1` is now `StaticSHA256` and is implemented using the `StaticSize 64 ByteString` for improved performance. See [#3006](https://github.com/commercialhaskell/stack/issues/3006) * Dependencies via HTTP(S) archives have been generalized to allow local file path archives, as well as to support setting a cryptographic hash (SHA256) of the contents for better reproducibility. * Allow specifying `--git-branch` when upgrading * When running `stack upgrade` from a file which is different from the default executable path (e.g., on POSIX systems, `~/.local/bin/stack`), it will now additionally copy the new executable over the currently running `stack` executable. If permission is denied (such as in `/usr/local/bin/stack`), the user will be prompted to try again using `sudo`. This is intended to assist with the user experience when the `PATH` environment variable has not been properly configured, see [#3232](https://github.com/commercialhaskell/stack/issues/3232). * `stack setup` for ghcjs will now install `alex` and `happy` if they are not present. See [#3109](https://github.com/commercialhaskell/stack/issues/3232). * Added `stack ghci --only-main` flag, to skip loading / importing all but main modules. See the ghci documentation page for further info. * Allow GHC's colored output to show through. GHC colors output starting with version 8.2.1, for older GHC this does nothing. Sometimes GHC's heuristics would work fine even before this change, for example in `stack ghci`, but this override's GHC's heuristics when they're broken by our collecting and processing GHC's output. * Extended the `ghc-options` key to support `$locals`, `$targets`, and `$everything`. See: [#3329](https://github.com/commercialhaskell/stack/issues/3329) * Better error message for case that `stack ghci` file targets are combined with invalid package targets. See: [#3342](https://github.com/commercialhaskell/stack/issues/3342) * For profiling now uses `-fprof-auto -fprof-cafs` instead of the deprecated `-auto-all -caf-all`. See: [#3360](https://github.com/commercialhaskell/stack/issues/3360) * Better descriptions are now available for `stack upgrade --help`. See: [#3070](https://github.com/commercialhaskell/stack/issues/3070) * When using Nix, nix-shell now depends always on gcc to prevent build errors when using the FFI. As ghc depends on gcc anyway, this doesn't increase the dependency footprint. * `--cwd DIR` can now be passed to `stack exec` in order to execute the program in a different directory. See: [#3264](https://github.com/commercialhaskell/stack/issues/3264) * Plan construction will detect if you add an executable-only package as a library dependency, resulting in much clearer error messages. See: [#2195](https://github.com/commercialhaskell/stack/issues/2195). * Addition of `--ghc-options` to `stack script` to pass options directly to GHC. See: [#3454](https://github.com/commercialhaskell/stack/issues/3454) * Add Hpack `package.yaml` to build Stack itself * Add `ignore-revision-mismatch` setting. See: [#3520](https://github.com/commercialhaskell/stack/issues/3520). * Log when each individual test suite finishes. See: [#3552](https://github.com/commercialhaskell/stack/issues/3552). * Avoid spurious rebuilds when using `--file-watch` by not watching files for executable, test and benchmark components that aren't a target. See: [#3483](https://github.com/commercialhaskell/stack/issues/3483). * Stack will now try to detect the width of the running terminal (only on POSIX for the moment) and use that to better display output messages. Work is ongoing, so some messages will not be optimal yet. The terminal width can be overridden with the new `--terminal-width` command-line option (this works even on non-POSIX). * Passing non local packages as targets to `stack ghci` will now cause them to be used as `-package` args along with package hiding. * Detect when user changed Cabal file instead of `package.yaml`. This was implemented upstream in Hpack. See [#3383](https://github.com/commercialhaskell/stack/issues/3383). * Automatically run `autoreconf -i` as necessary when a `configure` script is missing. See [#3534](https://github.com/commercialhaskell/stack/issues/3534) * GHC binary distributions can now be identified by their SHA256 checksum in addition to their SHA1 checksum, allowing for more security in download. * For filesystem setup-info paths, it's no longer assumed that the directory is writable, instead a temp dir is used. See [#3188](https://github.com/commercialhaskell/stack/issues/3188). Bug fixes: * `stack hoogle` correctly generates Hoogle databases. See: [#3362](https://github.com/commercialhaskell/stack/issues/3362) * `stack --docker-help` is now clearer about --docker implying system-ghc: true, rather than both --docker and --no-docker. * `stack haddock` now includes package names for all modules in the Haddock index page. See: [#2886](https://github.com/commercialhaskell/stack/issues/2886) * Fixed an issue where Stack wouldn't detect missing Docker images properly with newer Docker versions. [#3171](https://github.com/commercialhaskell/stack/pull/3171) * Previously, Cabal files with just test-suite could cause build to fail ([#2862](https://github.com/commercialhaskell/stack/issues/2862)) * If an invalid snapshot file has been detected (usually due to mismatched hashes), Stack will delete the downloaded file and recommend either retrying or filing an issue upstream. See [#3319](https://github.com/commercialhaskell/stack/issues/3319). * Modified the flag parser within Stack to match the behavior of Cabal's flag parser, which allows multiple sequential dashes. See [#3345](https://github.com/commercialhaskell/stack/issues/3345) * Now clears the hackage index cache if it is older than the downloaded index. Fixes potential issue if Stack was interrupted when updating index. See [#3033](https://github.com/commercialhaskell/stack/issues/3033) * The Stack install script now respects the `-d` option. See [#3366](https://github.com/commercialhaskell/stack/pull/3366). * `stack script` can now handle relative paths to source files. See [#3372](https://github.com/commercialhaskell/stack/issues/3372). * Fixes explanation of why a target is needed by the build plan, when the target is an extra-dep from the commandline. See [#3378](https://github.com/commercialhaskell/stack/issues/3378). * Previously, if you delete a yaml file from ~/.stack/build-plan, it would trust the etag and not re-download. Fixed in this version. * Invoking `stack --docker` in parallel now correctly locks the sqlite database. See [#3400](https://github.com/commercialhaskell/stack/issues/3400). * docs.haskellstack.org RTD documentation search is replaced by the mkdocs search. Please see [#3376](https://github.com/commercialhaskell/stack/issues/3376). * `stack clean` now works with nix. See [#3468](https://github.com/commercialhaskell/stack/issues/3376). * `stack build --only-dependencies` no longer builds local project packages that are depended on. See [#3476](https://github.com/commercialhaskell/stack/issues/3476). * Properly handle relative paths stored in the precompiled cache files. See [#3431](https://github.com/commercialhaskell/stack/issues/3431). * In some cases, Cabal does not realize that it needs to reconfigure, and must be told to do so automatically. This would manifest as a "shadowed dependency" error message. We now force a reconfigure whenever a dependency is built, even if the package ID remained the same. See [#2781](https://github.com/commercialhaskell/stack/issues/2781). * When `--pvp-bounds` is enabled for sdist or upload, internal dependencies could cause errors when uploaded to hackage. This is fixed, see [#3290](https://github.com/commercialhaskell/stack/issues/3290) * Fixes a bug where nonexistent hackage versions would cause Stack to suggest the same package name, without giving version info. See [#3562](https://github.com/commercialhaskell/stack/issues/3562) * Fixes a bug that has existed since 1.5.0, where `stack setup --upgrade-cabal` would say that Cabal is already the latest version, when it wasn't. * Ensure that an `extra-dep` from a local directory is not treated as a `$locals` for GHC options purposes. See [#3574](https://github.com/commercialhaskell/stack/issues/3574). * Building all executables only happens once instead of every time. See [#3229](https://github.com/commercialhaskell/stack/issues/3229) for more info. ## 1.5.1 - 2017-08-05 Bug fixes: * Stack eagerly tries to parse all Cabal files related to a snapshot. Starting with Stackage Nightly 2017-07-31, snapshots are using GHC 8.2.1, and the `ghc.cabal` file implicitly referenced uses the (not yet supported) Cabal 2.0 file format. Future releases of Stack will both be less eager about Cabal file parsing and support Cabal 2.0. This patch simply bypasses the error for invalid parsing. ## 1.5.0 - 2017-07-25 Behavior changes: * `stack profile` and `stack trace` now add their extra RTS arguments for benchmarks and tests to the beginning of the args, instead of the end. See [#2399](https://github.com/commercialhaskell/stack/issues/2399) * Support for Git-based indices has been removed. Other enhancements: * `stack setup` allow to control options passed to ghcjs-boot with `--ghcjs-boot-options` (one word at a time) and `--[no-]ghcjs-boot-clean` * `stack setup` now accepts a `--install-cabal VERSION` option which will install a specific version of the Cabal library globally. * Updates to store-0.4.1, which has improved performance and better error reporting for version tags. A side-effect of this is that all of stack's binary caches will be invalidated. * `stack solver` will now warn about unexpected `cabal-install` versions. See [#3044](https://github.com/commercialhaskell/stack/issues/3044) * Upstream packages unpacked to a temp dir are now deleted as soon as possible to avoid running out of space in `/tmp`. See [#3018](https://github.com/commercialhaskell/stack/issues/3018) * Add short synonyms for `test-arguments` and `benchmark-arguments` options. * Adds `STACK_WORK` environment variable, to specify work dir. See [#3063](https://github.com/commercialhaskell/stack/issues/3063) * Can now use relative paths for `extra-include-dirs` and `extra-lib-dirs`. See [#2830](https://github.com/commercialhaskell/stack/issues/2830) * Improved bash completion for many options, including `--ghc-options`, `--flag`, targets, and project executables for `exec`. * `--haddock-arguments` is actually used now when `haddock` is invoked during documentation generation. * `--[no-]haddock-hyperlink-source` flag added which allows toggling of sources being included in Haddock output. See [#3099](https://github.com/commercialhaskell/stack/issues/3099) * `stack ghci` will now skip building all local targets, even if they have downstream deps, as long as it's registered in the DB. * The `pvp-bounds` feature now supports adding `-revision` to the end of each value, e.g. `pvp-bounds: both-revision`. This means that, when uploading to Hackage, Stack will first upload your tarball with an unmodified Cabal file, and then upload a Cabal file revision with the PVP bounds added. This can be useful - especially combined with the [Stackage no-revisions feature](http://www.snoyman.com/blog/2017/04/stackages-no-revisions-field) - as a method to ensure PVP compliance without having to proactively fix bounds issues for Stackage maintenance. * Expose a `save-hackage-creds` configuration option * On GHC <= 7.8, filters out spurious linker warnings on windows See [#3127](https://github.com/commercialhaskell/stack/pull/3127) * Better error messages when creating or building packages which alias wired-in packages. See [#3172](https://github.com/commercialhaskell/stack/issues/3172). * MinGW bin folder now is searched for dynamic libraries. See [#3126](https://github.com/commercialhaskell/stack/issues/3126) * When using Nix, nix-shell now depends always on git to prevent runtime errors while fetching metadata * Experimental: The `stack unpack` command now accepts a form where an explicit Hackage revision hash is specified, e.g. `stack unpack foo-1.2.3@gitsha1:deadbeef`. Note that Stack will likely move towards a different hash format in the future. * Binary "stack upgrade" will now warn if the installed executable is not on the PATH or shadowed by another entry. * Allow running tests on tarball created by sdist and upload [#717](https://github.com/commercialhaskell/stack/issues/717). Bug fixes: * Fixes case where `stack build --profile` might not cause executables / tests / benchmarks to be rebuilt. See [#2984](https://github.com/commercialhaskell/stack/issues/2984) * `stack ghci file.hs` now loads the file even if it isn't part of your project. * `stack clean --full` now works when docker is enabled. See [#2010](https://github.com/commercialhaskell/stack/issues/2010) * Fixes an issue where cyclic deps can cause benchmarks or tests to be run before they are built. See [#2153](https://github.com/commercialhaskell/stack/issues/2153) * Fixes `stack build --file-watch` in cases where a directory is removed See [#1838](https://github.com/commercialhaskell/stack/issues/1838) * Fixes `stack dot` and `stack list-dependencies` to use info from the package database for wired-in-packages (ghc, base, etc). See [#3084](https://github.com/commercialhaskell/stack/issues/3084) * Fixes `stack --docker build` when user is part of libvirt/libvirtd groups on Ubuntu Yakkety (16.10). See [#3092](https://github.com/commercialhaskell/stack/issues/3092) * Switching a package between extra-dep and local package now forces rebuild (previously it wouldn't if versions were the same). See [#2147](https://github.com/commercialhaskell/stack/issues/2147) * `stack upload` no longer reveals your password when you type it on MinTTY-based Windows shells, such as Cygwin and MSYS2. See [#3142](https://github.com/commercialhaskell/stack/issues/3142) * `stack script`'s import parser will now properly parse files that have Windows-style line endings (CRLF) ## 1.4.0 - 2017-03-15 Release notes: * Docker images: [fpco/stack-full](https://hub.docker.com/r/fpco/stack-full/) and [fpco/stack-run](https://hub.docker.com/r/fpco/stack-run/) are no longer being built for LTS 8.0 and above. [fpco/stack-build](https://hub.docker.com/r/fpco/stack-build/) images continue to be built with a [simplified process](https://github.com/commercialhaskell/stack/tree/master/etc/dockerfiles/stack-build). [#624](https://github.com/commercialhaskell/stack/issues/624) Major changes: * A new command, `script`, has been added, intended to make the script interpreter workflow more reliable, easier to use, and more efficient. This command forces the user to provide a `--resolver` value, ignores all config files for more reproducible results, and optimizes the existing package check to make the common case of all packages already being present much faster. This mode does require that all packages be present in a snapshot, however. [#2805](https://github.com/commercialhaskell/stack/issues/2805) Behavior changes: * The default package metadata backend has been changed from Git to the 01-index.tar.gz file, from the hackage-security project. This is intended to address some download speed issues from GitHub for people in certain geographic regions. There is now full support for checking out specific Cabal file revisions from downloaded tarballs as well. If you manually specify a package index with only a Git URL, Git will still be used. See [#2780](https://github.com/commercialhaskell/stack/issues/2780) * When you provide the `--resolver` argument to the `stack unpack` command, any packages passed in by name only will be looked up in the given snapshot instead of taking the latest version. For example, `stack --resolver lts-7.14 unpack mtl` will get version 2.2.1 of `mtl`, regardless of the latest version available in the package indices. This will also force the same Cabal file revision to be used as is specified in the snapshot. Unpacking via a package identifier (e.g. `stack --resolver lts-7.14 unpack mtl-2.2.1`) will ignore any settings in the snapshot and take the most recent revision. For backwards compatibility with tools relying on the presence of a `00-index.tar`, Stack will copy the `01-index.tar` file to `00-index.tar`. Note, however, that these files are different; most importantly, 00-index contains only the newest revisions of Cabal files, while 01-index contains all versions. You may still need to update your tooling. * Passing `--(no-)nix-*` options now no longer implies `--nix`, except for `--nix-pure`, so that the user preference whether or not to use Nix is honored even in the presence of options that change the Nix behavior. Other enhancements: * Internal cleanup: configuration types are now based much more on lenses * `stack build` and related commands now allow the user to disable debug symbol stripping with new `--no-strip`, `--no-library-stripping`, and `--no-executable-shipping` flags, closing [#877](https://github.com/commercialhaskell/stack/issues/877). Also turned error message for missing targets more readable ([#2384](https://github.com/commercialhaskell/stack/issues/2384)) * `stack haddock` now shows index.html paths when documentation is already up to date. Resolved [#781](https://github.com/commercialhaskell/stack/issues/781) * Respects the `custom-setup` stanza introduced in Cabal 1.24. This supercedes any `explicit-setup-deps` settings in your `stack.yaml` and trusts the package's Cabal file to explicitly state all its dependencies. * If system package installation fails, `get-stack.sh` will fail as well. Also shows warning suggesting to run `apt-get update` or similar, depending on the OS. ([#2898](https://github.com/commercialhaskell/stack/issues/2898)) * When `stack ghci` is run with a config with no packages (e.g. global project), it will now look for source files in the current work dir. ([#2878](https://github.com/commercialhaskell/stack/issues/2878)) * Bump to Hpack 0.17.0 to allow `custom-setup` and `!include "..."` in `package.yaml`. * The script interpreter will now output error logging. In particular, this means it will output info about plan construction errors. ([#2879](https://github.com/commercialhaskell/stack/issues/2879)) * `stack ghci` now takes `--flag` and `--ghc-options` again (inadvertently removed in 1.3.0). ([#2986](https://github.com/commercialhaskell/stack/issues/2986)) * `stack exec` now takes `--rts-options` which passes the given arguments inside of `+RTS ... args .. -RTS` to the executable. This works around Stack itself consuming the RTS flags on Windows. ([#2640](https://github.com/commercialhaskell/stack/issues/2640)) * Upgraded `http-client-tls` version, which now offers support for the `socks5://` and `socks5h://` values in the `http_proxy` and `https_proxy` environment variables. Bug fixes: * Bump to Hpack 0.16.0 to avoid character encoding issues when reading and writing on non-UTF8 systems. * `stack ghci` will no longer ignore hsSourceDirs that contain `..`. ([#2895](https://github.com/commercialhaskell/stack/issues/2895)) * `stack list-dependencies --license` now works for wired-in-packages, like base. ([#2871](https://github.com/commercialhaskell/stack/issues/2871)) * `stack setup` now correctly indicates when it uses system ghc ([#2963](https://github.com/commercialhaskell/stack/issues/2963)) * Fix to `stack config set`, in 1.3.2 it always applied to the global project. ([#2709](https://github.com/commercialhaskell/stack/issues/2709)) * Previously, Cabal files without exe or lib would fail on the "copy" step. ([#2862](https://github.com/commercialhaskell/stack/issues/2862)) * `stack upgrade --git` now works properly. Workaround for affected versions (>= 1.3.0) is to instead run `stack upgrade --git --source-only`. ([#2977](https://github.com/commercialhaskell/stack/issues/2977)) * Added support for GHC 8's slightly different warning format for dumping warnings from logs. * Work around a bug in Cabal/GHC in which package IDs are not unique for different source code, leading to Stack not always rebuilding packages depending on local packages which have changed. ([#2904](https://github.com/commercialhaskell/stack/issues/2904)) ## 1.3.2 - 2016-12-27 Bug fixes: * `stack config set` can now be used without a compiler installed [#2852](https://github.com/commercialhaskell/stack/issues/2852). * `get-stack.sh` now installs correct executable on ARM for generic Linux and raspbian, closing [#2856](https://github.com/commercialhaskell/stack/issues/2856). * Correct the testing of whether a package database exists by checking for the `package.cache` file itself instead of the containing directory. * Revert a change in the previous release which made it impossible to set local extra-dep packages as targets. This was overkill; we really only wanted to disable their test suites, which was already handled by a later patch. [#2849](https://github.com/commercialhaskell/stack/issues/2849) * `stack new` always treats templates as being UTF-8 encoding, ignoring locale settings on a local machine. See [Yesod mailing list discussion](https://groups.google.com/d/msg/yesodweb/ZyWLsJOtY0c/aejf9E7rCAAJ) ## 1.3.0 - 2016-12-12 Release notes: * For the _next_ Stack release after this one, we are planning changes to our Linux releases, including dropping our Ubuntu, Debian, CentOS, and Fedora package repositories and switching to statically-linked executables. See [#2534](https://github.com/commercialhaskell/stack/issues/2534). Note that upgrading without a package manager has gotten easier with new binary upgrade support in `stack upgrade` (see the Major Changes section below for more information). In addition, the get.haskellstack.org script no longer installs from Ubuntu, Debian, CentOS, or Fedora package repositories. Instead it places a generic executable in /usr/local/bin. Major changes: * Stack will now always use its own GHC installation, even when a suitable GHC installation is available on the PATH. To get the old behaviour, use the `--system-ghc` flag or run `stack config set system-ghc --global true`. Docker- and Nix-enabled projects continue to use the GHC installations in their environment by default. NB: Scripts that previously used Stack in combination with a system GHC installation should now include a `stack setup` line or use the `--install-ghc` flag. [#2221](https://github.com/commercialhaskell/stack/issues/2221) * `stack ghci` now defaults to skipping the build of target packages, because support has been added for invoking "initial build steps", which create autogen files and run preprocessors. The `--no-build` flag is now deprecated because it should no longer be necessary. See [#1364](https://github.com/commercialhaskell/stack/issues/1364) * Stack is now capable of doing binary upgrades instead of always recompiling a new version from source. Running `stack upgrade` will now default to downloading a Stack executable from the most recent release, if one is available. See `stack upgrade --help` for more options. [#1238](https://github.com/commercialhaskell/stack/issues/1238) Behavior changes: * Passing `--resolver X` with a Stack command which forces creation of a global project config, will pass resolver X into the initial config. See [#2579](https://github.com/commercialhaskell/stack/issues/2229). * Switch the "Run from outside project" messages to debug-level, to avoid spamming users in the normal case of non-project usage * If a remote package is specified (such as a Git repo) without an explicit `extra-dep` setting, a warning is given to the user to provide one explicitly. Other enhancements: * `stack haddock` now supports `--haddock-internal`. See [#2229](https://github.com/commercialhaskell/stack/issues/2229) * Add support for `system-ghc` and `install-ghc` subcommands to `stack config set` command. * Add `ghc-build` option to override autodetected GHC build to use (e.g. gmp4, tinfo6, nopie) on Linux. * `stack setup` detects systems where gcc enables PIE by default (such as Ubuntu 16.10 and Hardened Gentoo) and adjusts the GHC `configure` options accordingly. [#2542](https://github.com/commercialhaskell/stack/issues/2542) * Upload to Hackage with HTTP digest instead of HTTP basic. * Make `stack list-dependencies` understand all of the `stack dot` options too. * Add the ability for `stack list-dependencies` to list dependency licenses by passing the `--license` flag. * Dump logs that contain warnings for any local non-dependency packages [#2545](https://github.com/commercialhaskell/stack/issues/2545) * Add the `dump-logs` config option and `--dump-logs` command line option to get full build output on the console. [#426](https://github.com/commercialhaskell/stack/issues/426) * Add the `--open` option to "stack hpc report" command, causing the report to be opened in the browser. * The `stack config set` command now accepts a `--global` flag for suitable subcommands which causes it to modify the global user configuration (`~/.stack/config.yaml`) instead of the project configuration. [#2675](https://github.com/commercialhaskell/stack/pull/2675) * Information on the latest available snapshots is now downloaded from S3 instead of stackage.org, increasing reliability in case of stackage.org outages. [#2653](https://github.com/commercialhaskell/stack/pull/2653) * `stack dot` and `stack list-dependencies` now take targets and flags. [#1919](https://github.com/commercialhaskell/stack/issues/1919) * Deprecate `stack setup --stack-setup-yaml` for `--setup-info-yaml` based on discussion in [#2647](https://github.com/commercialhaskell/stack/issues/2647). * The `--main-is` flag for GHCI now implies the TARGET, fixing [#1845](https://github.com/commercialhaskell/stack/issues/1845). * `stack ghci` no longer takes all build options, as many weren't useful [#2199](https://github.com/commercialhaskell/stack/issues/2199) * `--no-time-in-log` option, to make verbose logs more diffable [#2727](https://github.com/commercialhaskell/stack/issues/2727) * `--color` option added to override auto-detection of ANSI support [#2725](https://github.com/commercialhaskell/stack/issues/2725) * Missing extra-deps are now warned about, adding a degree of typo detection [#1521](https://github.com/commercialhaskell/stack/issues/1521) * No longer warns about missing build-tools if they are on the PATH. [#2235](https://github.com/commercialhaskell/stack/issues/2235) * Replace enclosed-exceptions with safe-exceptions. [#2768](https://github.com/commercialhaskell/stack/issues/2768) * The install location for GHC and other programs can now be configured with the `local-programs-path` option in `config.yaml`. [#1644](https://github.com/commercialhaskell/stack/issues/1644) * Added option to add nix dependencies as nix GC roots * Proper pid 1 (init) process for `stack exec` with Docker * Dump build logs if they contain warnings. [#2545](https://github.com/commercialhaskell/stack/issues/2545) * Docker: redirect stdout of `docker pull` to stderr so that it will not interfere with output of other commands. * Nix & docker can be activated at the same time, in order to run Stack in a nix-shell in a container, preferably from an image already containing the nix dependencies in its /nix/store * Stack/nix: Dependencies can be added as nix GC roots, so they are not removed when running `nix-collect-garbage` Bug fixes: * Fixed a gnarly bug where programs and package tarballs sometimes have corrupted downloads. See [#2657](https://github.com/commercialhaskell/stack/issues/2568). * Add proper support for non-ASCII characters in file paths for the `sdist` command. See [#2549](https://github.com/commercialhaskell/stack/issues/2549) * Never treat `extra-dep` local packages as targets. This ensures things like test suites are not run for these packages, and that build output is not hidden due to their presence. * Fix a resource leak in `sinkProcessStderrStdout` which could affect much of the codebase, in particular copying precompiled packages. [#1979](https://github.com/commercialhaskell/stack/issues/1979) * Docker: ensure that interrupted extraction process does not cause corrupt file when downloading a Docker-compatible Stack executable [#2568](https://github.com/commercialhaskell/stack/issues/2568) * Fixed running `stack hpc report` on package targets. [#2664](https://github.com/commercialhaskell/stack/issues/2664) * Fix a long-standing performance regression where Stack would parse the `.dump-hi` files of the library components of local packages twice. [#2658](https://github.com/commercialhaskell/stack/pull/2658) * Fixed a regression in "stack ghci --no-load", where it would prompt for a main module to load. [#2603](https://github.com/commercialhaskell/stack/pull/2603) * Build Setup.hs files with the threaded RTS, mirroring the behavior of `cabal-install` and enabling more complex build systems in those files. * Fixed a bug in passing along `--ghc-options` to ghcjs. They were being provided as `--ghc-options` to Cabal, when it needs to be `--ghcjs-options`. [#2714](https://github.com/commercialhaskell/stack/issues/2714) * Launch Docker from the project root regardless of the working directory Stack is invoked from. This means paths relative to the project root (e.g. environment files) can be specified in `stack.yaml`'s docker `run-args`. * `stack setup --reinstall` now behaves as expected. [#2554](https://github.com/commercialhaskell/stack/issues/2554) ## 1.2.0 - 2016-09-16 Release notes: * On many Un*x systems, Stack can now be installed with a simple one-liner: wget -qO- https://get.haskellstack.org/ | sh * The fix for [#2175](https://github.com/commercialhaskell/stack/issues/2175) entails that Stack must perform a full clone of a large Git repo of Hackage meta-information. The total download size is about 200 MB. Please be aware of this when upgrading your Stack installation. * If you use Mac OS X, you may want to delay upgrading to macOS Sierra as there are reports of GHC panics when building some packages (including Stack itself). See [#2577](https://github.com/commercialhaskell/stack/issues/2577) * This version of Stack does not build on ARM or PowerPC systems (see [store#37](https://github.com/fpco/store/issues/37)). Please stay with version 1.1.2 for now on those architectures. This will be rectified soon! * We are now releasing a statically-linked Stack executable for [64-bit Linux](https://get.haskellstack.org/stable/linux-x86_64-static.tar.gz). Please try it and let us know if you run into any trouble on your platform. The executable is linked against a version of the GNU Multiple Precision Arithmetic Library (GMP), which is licensed under the GNU Lesser General Public License, Version 3, 29 June 2007 (LGPL). * We are planning some changes to our Linux releases, including dropping our Ubuntu, Debian, CentOS, and Fedora package repositories and switching to statically-linked executables. We would value your feedback in [#2534](https://github.com/commercialhaskell/stack/issues/2534). Major changes: * Add `stack hoogle` command. [#55](https://github.com/commercialhaskell/stack/issues/55) * Support for absolute file path in `url` key of `setup-info` or `--ghc-bindist` * Add support for rendering GHCi scripts targeting different GHCi like applications [#2457](https://github.com/commercialhaskell/stack/pull/2457) Behavior changes: * Remove `stack ide start` and `stack ide load-targets` commands. [#2178](https://github.com/commercialhaskell/stack/issues/2178) * Support .buildinfo files in `stack ghci`. [#2242](https://github.com/commercialhaskell/stack/pull/2242) * Support -ferror-spans syntax in GHC error messages. * Avoid unpacking ghc to `/tmp` [#996](https://github.com/commercialhaskell/stack/issues/996) * The Linux `gmp4` GHC binary distribution is no longer considered a full-fledged GHC variant and can no longer be specified using the `ghc-variant` option, and instead is treated more like a slightly different platform. Other enhancements: * Use the `store` package for binary serialization of most caches. * Only require minor version match for Docker Stack exe. This way, we can make patch releases for version bounds and similar build issues without needing to upload new binaries for Docker. * Stack/Nix: Passes the right ghc derivation as an argument to the `shell.nix` when a custom `shell.nix` is used. See [#2243](https://github.com/commercialhaskell/stack/issues/2243) * Stack/Nix: Sets `LD_LIBRARY_PATH` so packages using C libs for Template Haskell can work (See _e.g._ [this HaskellR issue](https://github.com/tweag/HaskellR/issues/253)) * Parse CLI arguments and configuration files into less permissive types, improving error messages for bad inputs. [#2267](https://github.com/commercialhaskell/stack/issues/2267) * Add the ability to explicitly specify a gcc executable. [#593](https://github.com/commercialhaskell/stack/issues/593) * Nix: No longer uses LTS mirroring in nixpkgs. Gives to nix-shell a derivation like `haskell.compiler.ghc801` See [#2259](https://github.com/commercialhaskell/stack/issues/2259) * Perform some subprocesses during setup concurrently, slightly speeding up most commands. [#2346](https://github.com/commercialhaskell/stack/pull/2346) * `stack setup` no longer unpacks to the system temp dir on posix systems. [#996](https://github.com/commercialhaskell/stack/issues/996) * `stack setup` detects libtinfo6 and ncurses6 and can download alternate GHC binary distributions [#257](https://github.com/commercialhaskell/stack/issues/257) [#2302](https://github.com/commercialhaskell/stack/issues/2302). * `stack setup` detects Linux ARMv7 downloads appropriate GHC binary distribution [#2103](https://github.com/commercialhaskell/stack/issues/2103) * Custom `stack` binaries list dependency versions in output for `--version`. See [#2222](https://github.com/commercialhaskell/stack/issues/2222) and [#2450](https://github.com/commercialhaskell/stack/issues/2450). * Use a pretty printer to output dependency resolution errors. [#1912](https://github.com/commercialhaskell/stack/issues/1912) * Remove the `--os` flag [#2227](https://github.com/commercialhaskell/stack/issues/2227) * Add 'netbase' and 'ca-certificates' as dependency for .deb packages. [#2293](https://github.com/commercialhaskell/stack/issues/2293). * Add `stack ide targets` command. * Enhance debug logging with subprocess timings. * Pretty-print YAML parse errors [#2374](https://github.com/commercialhaskell/stack/issues/2374) * Clarify confusing `stack setup` output [#2314](https://github.com/commercialhaskell/stack/issues/2314) * Delete `Stack.Types` multimodule to improve build times [#2405](https://github.com/commercialhaskell/stack/issues/2405) * Remove spurious newlines in build logs [#2418](https://github.com/commercialhaskell/stack/issues/2418) * Interpreter: Provide a way to hide implicit packages [#1208](https://github.com/commercialhaskell/stack/issues/1208) * Check executability in exec lookup [#2489](https://github.com/commercialhaskell/stack/issues/2489) Bug fixes: * Fix Cabal warning about use of a deprecated Cabal flag [#2350](https://github.com/commercialhaskell/stack/issues/2350) * Support most executable extensions on Windows [#2225](https://github.com/commercialhaskell/stack/issues/2225) * Detect resolver change in `stack solver` [#2252](https://github.com/commercialhaskell/stack/issues/2252) * Fix a bug in docker image creation where the wrong base image was selected [#2376](https://github.com/commercialhaskell/stack/issues/2376) * Ignore special entries when unpacking tarballs [#2361](https://github.com/commercialhaskell/stack/issues/2361) * Fixes src directory pollution of `style.css` and `highlight.js` with GHC 8's haddock [#2429](https://github.com/commercialhaskell/stack/issues/2429) * Handle filepaths with spaces in `stack ghci` [#2266](https://github.com/commercialhaskell/stack/issues/2266) * Apply ghc-options to snapshot packages [#2289](https://github.com/commercialhaskell/stack/issues/2289) * `stack sdist`: Fix timestamp in tarball [#2394](https://github.com/commercialhaskell/stack/pull/2394) * Allow global Stack arguments with a script [#2316](https://github.com/commercialhaskell/stack/issues/2316) * Inconsistency between ToJSON and FromJSON instances of PackageLocation [#2412](https://github.com/commercialhaskell/stack/pull/2412) * Perform Unicode normalization on filepaths [#1810](https://github.com/commercialhaskell/stack/issues/1810) * Solver: always keep ghc wired-in as hard constraints [#2453](https://github.com/commercialhaskell/stack/issues/2453) * Support OpenBSD's tar where possible, require GNU tar for xz support [#2283](https://github.com/commercialhaskell/stack/issues/2283) * Fix using --coverage with Cabal-1.24 [#2424](https://github.com/commercialhaskell/stack/issues/2424) * When marking exe installed, remove old version [#2373](https://github.com/commercialhaskell/stack/issues/2373) * Stop truncating `all-cabal-hashes` git repo [#2175](https://github.com/commercialhaskell/stack/issues/2175) * Handle non-ASCII filenames on Windows [#2491](https://github.com/commercialhaskell/stack/issues/2491) * Avoid using multiple versions of a package in script interpreter by passing package-id to ghc/runghc [#1957](https://github.com/commercialhaskell/stack/issues/1957) * Only pre-load compiler version when using nix integration [#2459](https://github.com/commercialhaskell/stack/issues/2459) * Solver: parse Cabal errors also on Windows [#2502](https://github.com/commercialhaskell/stack/issues/2502) * Allow exec and ghci commands in interpreter mode. Scripts can now automatically open in the repl by using `exec ghci` instead of `runghc` in the shebang command. [#2510](https://github.com/commercialhaskell/stack/issues/2510) * Now consider a package to be dirty when an extra-source-file is changed. See [#2040](https://github.com/commercialhaskell/stack/issues/2040) ## 1.1.2 - 2016-05-20 Release notes: * Official FreeBSD binaries are [now available](http://docs.haskellstack.org/en/stable/install_and_upgrade/#freebsd) [#1253](https://github.com/commercialhaskell/stack/issues/1253). Major changes: * Extensible custom snapshots implemented. These allow you to define snapshots which extend other snapshots. See [#863](https://github.com/commercialhaskell/stack/issues/863). Local file custom snapshots can now be safely updated without changing their name. Remote custom snapshots should still be treated as immutable. Behavior changes: * `stack path --compiler` was added in the last release, to yield a path to the compiler. Unfortunately, `--compiler` is a global option that is useful to use with `stack path`. The same functionality is now provided by `stack path --compiler-exe`. See [#2123](https://github.com/commercialhaskell/stack/issues/2123) * For packages specified in terms of a git or hg repo, the hash used in the location has changed. This means that existing downloads from older stack versions won't be used. This is a side-effect of the fix to [#2133](https://github.com/commercialhaskell/stack/issues/2133) * `stack upgrade` no longer pays attention to local `stack.yaml` files, just the global config and CLI options. [#1392](https://github.com/commercialhaskell/stack/issues/1392) * `stack ghci` now uses `:add` instead of `:load`, making it potentially work better with user scripts. See [#1888](https://github.com/commercialhaskell/stack/issues/1888) Other enhancements: * Grab Cabal files via Git SHA to avoid regressions from Hackage revisions [#2070](https://github.com/commercialhaskell/stack/pull/2070) * Custom snapshots now support `ghc-options`. * Package git repos are now re-used rather than re-cloned. See [#1620](https://github.com/commercialhaskell/stack/issues/1620) * `DESTDIR` is filtered from environment when installing GHC. See [#1460](https://github.com/commercialhaskell/stack/issues/1460) * `stack haddock` now supports `--haddock-arguments`. See [#2144](https://github.com/commercialhaskell/stack/issues/2144) * Signing: warn if GPG_TTY is not set as per `man gpg-agent` Bug fixes: * Now ignore project config when doing `stack init` or `stack new`. See [#2110](https://github.com/commercialhaskell/stack/issues/2110) * Packages specified by git repo can now have submodules. See [#2133](https://github.com/commercialhaskell/stack/issues/2133) * Fix of hackage index fetch retry. See re-opening of [#1418](https://github.com/commercialhaskell/stack/issues/1418#issuecomment-217633843) * HPack now picks up changes to filesystem other than package.yaml. See [#2051](https://github.com/commercialhaskell/stack/issues/2051) * "stack solver" no longer suggests --omit-packages. See [#2031](https://github.com/commercialhaskell/stack/issues/2031) * Fixed an issue with building Cabal's Setup.hs. See [#1356](https://github.com/commercialhaskell/stack/issues/1356) * Package dirtiness now pays attention to deleted files. See [#1841](https://github.com/commercialhaskell/stack/issues/1841) * `stack ghci` now uses `extra-lib-dirs` and `extra-include-dirs`. See [#1656](https://github.com/commercialhaskell/stack/issues/1656) * Relative paths outside of source dir added via `qAddDependentFile` are now checked for dirtiness. See [#1982](https://github.com/commercialhaskell/stack/issues/1982) * Signing: always use `--with-fingerprints` ## 1.1.0 - 2016-05-04 Release notes: * Added Ubuntu 16.04 LTS (xenial) Apt repo. * No longer uploading new versions to Fedora 21 repo. Behavior changes: * Snapshot packages are no longer built with executable profiling. See [#1179](https://github.com/commercialhaskell/stack/issues/1179). * `stack init` now ignores symlinks when searching for Cabal files. It also now ignores any directory that begins with `.` (as well as `dist` dirs) - before it would only ignore `.git`, `.stack-work`, and `dist`. * The Stack executable is no longer built with `-rtsopts`. Before, when `-rtsopts` was enabled, Stack would process `+RTS` options even when intended for some other program, such as when used with `stack exec -- prog +RTS`. See [#2022](https://github.com/commercialhaskell/stack/issues/2022). * The `stack path --ghc-paths` option is deprecated and renamed to `--programs`. `--compiler` is added, which points directly at the compiler used in the current project. `--compiler-bin` points to the compiler's bin dir. * For consistency with the `$STACK_ROOT` environment variable, the `stack path --global-stack-root` flag and the `global-stack-root` field in the output of `stack path` are being deprecated and replaced with the `stack-root` flag and output field. Additionally, the Stack root can now be specified via the `--stack-root` command-line flag. See [#1148](https://github.com/commercialhaskell/stack/issues/1148). * `stack sig` GPG-related sub-commands were removed (folded into `upload` and `sdist`) * GPG signing of packages while uploading to Hackage is now the default. Use `upload --no-signature` if you would rather not contribute your package signature. If you don't yet have a GPG keyset, read this [blog post on GPG keys](https://fpcomplete.com/blog/2016/05/stack-security-gnupg-keys). We can add a `stack.yaml` config setting to disable signing if some people desire it. We hope that people will sign. Later we will be adding GPG signature verification options. * `stack build pkg-1.2.3` will now build even if the snapshot has a different package version - it is treated as an extra-dep. `stack build local-pkg-1.2.3` is an error even if the version number matches the local package [#2028](https://github.com/commercialhaskell/stack/issues/2028). * A `nix` key in a Stack YAML configuration file no longer implies enabling a Nix build. This allows the user to globally configure whether Nix is used (unless the project overrides the default explicitly). See [#1924](https://github.com/commercialhaskell/stack/issues/1924). * Remove deprecated `valid-wanted` key. * Docker: mount home directory in container [#1949](https://github.com/commercialhaskell/stack/issues/1949). * Deprecate `stack path --local-bin-path`; instead use `--local-bin`. * `stack image`: allow absolute source paths for `add`. Other enhancements: * `stack haddock --open [PACKAGE]` opens the local haddocks in the browser. * Fix too much rebuilding when enabling/disabling profiling flags. * `stack build pkg-1.0` will now build `pkg-1.0` even if the snapshot specifies a different version (it introduces a temporary extra-dep) * Experimental: Support for `--split-objs` added [#1284](https://github.com/commercialhaskell/stack/issues/1284). * `git` packages with submodules are supported by passing the `--recursive` flag to `git clone`. * When using [Hpack](https://github.com/sol/hpack), only regenerate Cabal files when Hpack files change. * Hpack files can now be used in templates * `stack ghci` now runs ghci as a separate process [#1306](https://github.com/commercialhaskell/stack/issues/1306) * Retry when downloading snapshots and package indices * Many build options are configurable now in `stack.yaml`: ~~~yaml build: library-profiling: true executable-profiling: true haddock: true haddock-deps: true copy-bins: true prefetch: true force-dirty: true keep-going: true test: true test-arguments: rerun-tests: true additional-args: ['-fprof'] coverage: true no-run-tests: true bench: true benchmark-opts: benchmark-arguments: -O2 no-run-benchmarks: true reconfigure: true cabal-verbose: true ~~~ * A number of URLs are now configurable, useful for firewalls. See [#1794](https://github.com/commercialhaskell/stack/issues/1884). * Suggest causes when executables are missing. * Allow `--omit-packages` even without `--solver`. * Improve the generated `stack.yaml`. * Improve ghci results after :load Main module collision with main file path. * Only load the hackage index if necessary [#1883](https://github.com/commercialhaskell/stack/issues/1883), [#1892](https://github.com/commercialhaskell/stack/issues/1892). * init: allow local packages to be deps of deps [#1965](https://github.com/commercialhaskell/stack/issues/1965). * Always use full fingerprints from GPG [#1952](https://github.com/commercialhaskell/stack/issues/1952). * Default to using `gpg2` and fall back to `gpg` [#1976](https://github.com/commercialhaskell/stack/issues/1976). * Add a flag for --verbosity silent. * Add `haddock --open` flag [#1396](https://github.com/commercialhaskell/stack/issues/1396). Bug fixes: * Package tarballs would fail to unpack. [#1884](https://github.com/commercialhaskell/stack/issues/1884). * Fixed errant warnings about missing modules, after deleted and removed from Cabal file [#921](https://github.com/commercialhaskell/stack/issues/921) [#1805](https://github.com/commercialhaskell/stack/issues/1805). * Now considers a package to dirty when the Hpack file is changed [#1819](https://github.com/commercialhaskell/stack/issues/1819). * Nix: cancelling a Stack build now exits properly rather than dropping into a nix-shell [#1778](https://github.com/commercialhaskell/stack/issues/1778). * `allow-newer: true` now causes `--exact-configuration` to be passed to Cabal. See [#1579](https://github.com/commercialhaskell/stack/issues/1579). * `stack solver` no longer fails with `InvalidRelFile` for relative package paths including `..`. See [#1954](https://github.com/commercialhaskell/stack/issues/1954). * Ignore emacs lock files when finding Cabal files [#1897](https://github.com/commercialhaskell/stack/issues/1897). * Use lenient UTF-8 decode for build output [#1945](https://github.com/commercialhaskell/stack/issues/1945). * Clear index cache whenever index updated [#1962](https://github.com/commercialhaskell/stack/issues/1962). * Fix: Building a container image drops a .stack-work dir in the current working (sub)directory [#1975](https://github.com/commercialhaskell/stack/issues/1975). * Fix: Rebuilding when disabling profiling [#2023](https://github.com/commercialhaskell/stack/issues/2023). ## 1.0.4.3 - 2016-04-07 Bug fixes: * Don't delete contents of ~/.ssh when using `stack clean --full` with Docker enabled [#2000](https://github.com/commercialhaskell/stack/issues/2000) ## 1.0.4.2 - 2016-03-09 Build with `path-io-1.0.0`. There are no changes in behaviour from 1.0.4, so no binaries are released for this version. ## 1.0.4.1 - 2016-02-21 Fixes build with `aeson-0.11.0.0`. There are no changes in behaviour from 1.0.4, so no binaries are released for this version. ## 1.0.4 - 2016-02-20 Major changes: * Some notable changes in `stack init`: * Overall it should now be able to initialize almost all existing Cabal packages out of the box as long as the package itself is consistently defined. * Choose the best possible snapshot and add extra-deps on top of a snapshot other than a compiler snapshot - [#1583](https://github.com/commercialhaskell/stack/pull/1583) * Automatically omit a package (`--omit-packages`) when it is compiler incompatible or when there are packages with conflicting dependency requirements. See [#1674](https://github.com/commercialhaskell/stack/pull/1674). * Some more changes for a better user experience. Please refer to the doc guide for details. * Add support for Hpack, alternative package description format [#1679](https://github.com/commercialhaskell/stack/issues/1679) Other enhancements: * Docker: pass ~/.ssh and SSH auth socket into container, so that git repos work [#1358](https://github.com/commercialhaskell/stack/issues/1358). * Docker: strip suffix from docker --version. [#1653](https://github.com/commercialhaskell/stack/issues/1653) * Docker: pass USER and PWD environment variables into container. * On each run, Stack will test the Stack root directory (~/.stack), and the project and package work directories (.stack-work) for whether they are owned by the current user and abort if they are not. This precaution can be disabled with the `--allow-different-user` flag or `allow-different-user` option in the global config (~/.stack/config.yaml). [#471](https://github.com/commercialhaskell/stack/issues/471) * Added `stack clean --full` option for full working dir cleanup. * YAML config: support Zip archives. * Redownload build plan if parsing fails [#1702](https://github.com/commercialhaskell/stack/issues/1702). * Give mustache templates access to a 'year' tag [#1716](https://github.com/commercialhaskell/stack/pull/1716). * Have "stack ghci" warn about module name aliasing. * Add "stack ghci --load-local-deps". * Build Setup.hs with -rtsopts [#1687](https://github.com/commercialhaskell/stack/issues/1687). * `stack init` accepts a list of directories. * Add flag infos to DependencyPlanFailures (for better error output in case of flags) [#713](https://github.com/commercialhaskell/stack/issues/713) * `stack new --bare` complains for overwrites, and add `--force` option [#1597](https://github.com/commercialhaskell/stack/issues/1597). Bug fixes: * Previously, `stack ghci` would fail with `cannot satisfy -package-id` when the implicit build step changes the package key of some dependency. * Fix: Building with ghcjs: "ghc-pkg: Prelude.chr: bad argument: 2980338" [#1665](https://github.com/commercialhaskell/stack/issues/1665). * Fix running test / bench with `--profile` / `--trace`. * Fix: build progress counter is no longer visible [#1685](https://github.com/commercialhaskell/stack/issues/1685). * Use "-RTS" w/ profiling to allow extra args [#1772](https://github.com/commercialhaskell/stack/issues/1772). * Fix withUnpackedTarball7z to find name of srcDir after unpacking (fixes `stack setup` fails for ghcjs project on windows) [#1774](https://github.com/commercialhaskell/stack/issues/1774). * Add space before auto-generated bench opts (makes profiling options work uniformly for applications and benchmark suites) [#1771](https://github.com/commercialhaskell/stack/issues/1771). * Don't try to find plugin if it resembles flag. * Setup.hs changes cause package dirtiness [#1711](https://github.com/commercialhaskell/stack/issues/1711). * Send "stack templates" output to stdout [#1792](https://github.com/commercialhaskell/stack/issues/1792). ## 1.0.2 - 2016-01-18 Release notes: - Arch Linux: Stack has been adopted into the [official community repository](https://www.archlinux.org/packages/community/x86_64/stack/), so we will no longer be updating the AUR with new versions. See the [install/upgrade guide](http://docs.haskellstack.org/en/stable/install_and_upgrade/#arch-linux) for current download instructions. Major changes: - `stack init` and `solver` overhaul [#1583](https://github.com/commercialhaskell/stack/pull/1583) Other enhancements: - Disable locale/codepage hacks when GHC >=7.10.3 [#1552](https://github.com/commercialhaskell/stack/issues/1552) - Specify multiple images to build for `stack image container` [docs](http://docs.haskellstack.org/en/stable/yaml_configuration/#image) - Specify which executables to include in images for `stack image container` [docs](http://docs.haskellstack.org/en/stable/yaml_configuration/#image) - Docker: pass supplementary groups and umask into container - If git fetch fails wipe the directory and try again from scratch [#1418](https://github.com/commercialhaskell/stack/issues/1418) - Warn if newly installed executables won't be available on the PATH [#1362](https://github.com/commercialhaskell/stack/issues/1362) - `stack.yaml`: for `stack image container`, specify multiple images to generate, and which executables should be added to those images - GHCI: add interactive Main selection [#1068](https://github.com/commercialhaskell/stack/issues/1068) - Care less about the particular name of a GHCJS sdist folder [#1622](https://github.com/commercialhaskell/stack/issues/1622) - Unified Enable/disable help messaging [#1613](https://github.com/commercialhaskell/stack/issues/1613) Bug fixes: - Don't share precompiled packages between GHC/platform variants and Docker [#1551](https://github.com/commercialhaskell/stack/issues/1551) - Properly redownload corrupted downloads with the correct file size. [Mailing list discussion](https://groups.google.com/d/msg/haskell-stack/iVGDG5OHYxs/FjUrR5JsDQAJ) - Gracefully handle invalid paths in error/warning messages [#1561](https://github.com/commercialhaskell/stack/issues/1561) - Nix: select the correct GHC version corresponding to the snapshot even when an abstract resolver is passed via `--resolver` on the command-line. [#1641](https://github.com/commercialhaskell/stack/issues/1641) - Fix: Stack does not allow using an external package from ghci [#1557](https://github.com/commercialhaskell/stack/issues/1557) - Disable ambiguous global '--resolver' option for 'stack init' [#1531](https://github.com/commercialhaskell/stack/issues/1531) - Obey `--no-nix` flag - Fix: GHCJS Execute.hs: Non-exhaustive patterns in lambda [#1591](https://github.com/commercialhaskell/stack/issues/1591) - Send file-watch and sticky logger messages to stderr [#1302](https://github.com/commercialhaskell/stack/issues/1302) [#1635](https://github.com/commercialhaskell/stack/issues/1635) - Use globaldb path for querying Cabal version [#1647](https://github.com/commercialhaskell/stack/issues/1647) ## 1.0.0 - 2015-12-24 Release notes: * We're calling this version 1.0.0 in preparation for Stackage LTS 4. Note, however, that this does not mean the code's API will be stable as this is primarily an end-user tool. Enhancements: * Added flag `--profile` flag: passed with `stack build`, it will enable profiling, and for `--bench` and `--test` it will generate a profiling report by passing `+RTS -p` to the executable(s). Great for using like `stack build --bench --profile` (remember that enabling profile will slow down your benchmarks by >4x). Run `stack build --bench` again to disable the profiling and get proper speeds * Added flag `--trace` flag: just like `--profile`, it enables profiling, but instead of generating a report for `--bench` and `--test`, prints out a stack trace on exception. Great for using like `stack build --test --trace` * Nix: all options can be overridden on command line [#1483](https://github.com/commercialhaskell/stack/issues/1483) * Nix: build environments (shells) are now pure by default. * Make verbosity silent by default in script interpreter mode [#1472](https://github.com/commercialhaskell/stack/issues/1472) * Show a message when resetting git commit fails [#1453](https://github.com/commercialhaskell/stack/issues/1453) * Improve Unicode handling in project/package names [#1337](https://github.com/commercialhaskell/stack/issues/1337) * Fix ambiguity between a Stack command and a filename to execute (prefer `stack` subcommands) [#1471](https://github.com/commercialhaskell/stack/issues/1471) * Support multi line interpreter directive comments [#1394](https://github.com/commercialhaskell/stack/issues/1394) * Handle space separated pids in ghc-pkg dump (for GHC HEAD) [#1509](https://github.com/commercialhaskell/stack/issues/1509) * Add ghci --no-package-hiding option [#1517](https://github.com/commercialhaskell/stack/issues/1517) * `stack new` can download templates from URL [#1466](https://github.com/commercialhaskell/stack/issues/1466) Bug fixes: * Nix: `stack exec` options are passed properly to the Stack sub process [#1538](https://github.com/commercialhaskell/stack/issues/1538) * Nix: specifying a shell-file works in any current working directory [#1547](https://github.com/commercialhaskell/stack/issues/1547) * Nix: use `--resolver` argument * Docker: fix missing image message and '--docker-auto-pull' * No HTML escaping for "stack new" template params [#1475](https://github.com/commercialhaskell/stack/issues/1475) * Set permissions for generated .ghci script [#1480](https://github.com/commercialhaskell/stack/issues/1480) * Restrict commands allowed in interpreter mode [#1504](https://github.com/commercialhaskell/stack/issues/1504) * `stack ghci` doesn't see preprocessed files for executables [#1347](https://github.com/commercialhaskell/stack/issues/1347) * All test suites run even when only one is requested [#1550](https://github.com/commercialhaskell/stack/pull/1550) * Edge cases in broken templates give odd errors [#1535](https://github.com/commercialhaskell/stack/issues/1535) * Fix test coverage bug on windows ## 0.1.10.1 - 2015-12-13 Bug fixes: * `stack image container` did not actually build an image [#1473](https://github.com/commercialhaskell/stack/issues/1473) ## 0.1.10.0 - 2015-12-04 Release notes: * The Stack home page is now at [haskellstack.org](http://haskellstack.org), which shows the documentation rendered by readthedocs.org. Note: this has necessitated some changes to the links in the documentation's markdown source code, so please check the links on the website before submitting a PR to fix them. * The locations of the [Ubuntu](http://docs.haskellstack.org/en/stable/install_and_upgrade/#ubuntu) and [Debian](http://docs.haskellstack.org/en/stable/install_and_upgrade/#debian) package repositories have changed to have correct URL semantics according to Debian's guidelines [#1378](https://github.com/commercialhaskell/stack/issues/1378). The old locations will continue to work for some months, but we suggest that you adjust your `/etc/apt/sources.list.d/fpco.list` to the new location to avoid future disruption. * [openSUSE and SUSE Linux Enterprise](http://docs.haskellstack.org/en/stable/install_and_upgrade/#suse) packages are now available, thanks to [@mimi1vx](https://github.com/mimi1vx). Note: there will be some lag before these pick up new versions, as they are based on Stackage LTS. Major changes: * Support for building inside a Nix-shell providing system dependencies [#1285](https://github.com/commercialhaskell/stack/pull/1285) * Add optional GPG signing on `stack upload --sign` or with `stack sig sign ...` Other enhancements: * Print latest applicable version of packages on conflicts [#508](https://github.com/commercialhaskell/stack/issues/508) * Support for packages located in Mercurial repositories [#1397](https://github.com/commercialhaskell/stack/issues/1397) * Only run benchmarks specified as build targets [#1412](https://github.com/commercialhaskell/stack/issues/1412) * Support git-style executable fall-through (`stack something` executes `stack-something` if present) [#1433](https://github.com/commercialhaskell/stack/issues/1433) * GHCi now loads intermediate dependencies [#584](https://github.com/commercialhaskell/stack/issues/584) * `--work-dir` option for overriding `.stack-work` [#1178](https://github.com/commercialhaskell/stack/issues/1178) * Support `detailed-0.9` tests [#1429](https://github.com/commercialhaskell/stack/issues/1429) * Docker: improved POSIX signal proxying to containers [#547](https://github.com/commercialhaskell/stack/issues/547) Bug fixes: * Show absolute paths in error messages in multi-package builds [#1348](https://github.com/commercialhaskell/stack/issues/1348) * Docker-built binaries and libraries in different path [#911](https://github.com/commercialhaskell/stack/issues/911) [#1367](https://github.com/commercialhaskell/stack/issues/1367) * Docker: `--resolver` argument didn't effect selected image tag * GHCi: Spaces in filepaths caused module loading issues [#1401](https://github.com/commercialhaskell/stack/issues/1401) * GHCi: cpp-options in Cabal files weren't used [#1419](https://github.com/commercialhaskell/stack/issues/1419) * Benchmarks couldn't be run independently of each other [#1412](https://github.com/commercialhaskell/stack/issues/1412) * Send output of building setup to stderr [#1410](https://github.com/commercialhaskell/stack/issues/1410) ## 0.1.8.0 - 2015-11-20 Major changes: * GHCJS can now be used with stackage snapshots via the new `compiler` key. * Windows installers are now available: [download them here](http://docs.haskellstack.org/en/stable/install_and_upgrade/#windows) [#613](https://github.com/commercialhaskell/stack/issues/613) * Docker integration works with non-FPComplete generated images [#531](https://github.com/commercialhaskell/stack/issues/531) Other enhancements: * Added an `allow-newer` config option [#922](https://github.com/commercialhaskell/stack/issues/922) [#770](https://github.com/commercialhaskell/stack/issues/770) * When a Hackage revision invalidates a build plan in a snapshot, trust the snapshot [#770](https://github.com/commercialhaskell/stack/issues/770) * Added a `stack config set resolver RESOLVER` command. Part of work on [#115](https://github.com/commercialhaskell/stack/issues/115) * `stack setup` can now install GHCJS on windows. See [#1145](https://github.com/commercialhaskell/stack/issues/1145) and [#749](https://github.com/commercialhaskell/stack/issues/749) * `stack hpc report` command added, which generates reports for HPC tix files * `stack ghci` now accepts all the flags accepted by `stack build`. See [#1186](https://github.com/commercialhaskell/stack/issues/1186) * `stack ghci` builds the project before launching GHCi. If the build fails, try to launch GHCi anyway. Use `stack ghci --no-build` option to disable [#1065](https://github.com/commercialhaskell/stack/issues/1065) * `stack ghci` now detects and warns about various circumstances where it is liable to fail. See [#1270](https://github.com/commercialhaskell/stack/issues/1270) * Added `require-docker-version` configuration option * Packages will now usually be built along with their tests and benchmarks. See [#1166](https://github.com/commercialhaskell/stack/issues/1166) * Relative `local-bin-path` paths will be relative to the project's root directory, not the current working directory. [#1340](https://github.com/commercialhaskell/stack/issues/1340) * `stack clean` now takes an optional `[PACKAGE]` argument for use in multi-package projects. See [#583](https://github.com/commercialhaskell/stack/issues/583) * Ignore cabal_macros.h as a dependency [#1195](https://github.com/commercialhaskell/stack/issues/1195) * Pad timestamps and show local time in --verbose output [#1226](https://github.com/commercialhaskell/stack/issues/1226) * GHCi: Import all modules after loading them [#995](https://github.com/commercialhaskell/stack/issues/995) * Add subcommand aliases: `repl` for `ghci`, and `runhaskell` for `runghc` [#1241](https://github.com/commercialhaskell/stack/issues/1241) * Add typo recommendations for unknown package identifiers [#158](https://github.com/commercialhaskell/stack/issues/158) * Add `stack path --local-hpc-root` option * Overhaul dependencies' haddocks copying [#1231](https://github.com/commercialhaskell/stack/issues/1231) * Support for extra-package-dbs in 'stack ghci' [#1229](https://github.com/commercialhaskell/stack/pull/1229) * `stack new` disallows package names with "words" consisting solely of numbers [#1336](https://github.com/commercialhaskell/stack/issues/1336) * `stack build --fast` turns off optimizations * Show progress while downloading package index [#1223](https://github.com/commercialhaskell/stack/issues/1223). Bug fixes: * Fix: Haddocks not copied for dependencies [#1105](https://github.com/commercialhaskell/stack/issues/1105) * Fix: Global options did not work consistently after subcommand [#519](https://github.com/commercialhaskell/stack/issues/519) * Fix: 'stack ghci' doesn't notice that a module got deleted [#1180](https://github.com/commercialhaskell/stack/issues/1180) * Rebuild when Cabal file is changed * Fix: Paths in GHC warnings not canonicalized, nor those for packages in subdirectories or outside the project root [#1259](https://github.com/commercialhaskell/stack/issues/1259) * Fix: unlisted files in tests and benchmarks trigger extraneous second build [#838](https://github.com/commercialhaskell/stack/issues/838) ## 0.1.6.0 - 2015-10-15 Major changes: * `stack setup` now supports building and booting GHCJS from source tarball. * On Windows, build directories no longer display "pretty" information (like x86_64-windows/Cabal-1.22.4.0), but rather a hash of that content. The reason is to avoid the 260 character path limitation on Windows. See [#1027](https://github.com/commercialhaskell/stack/pull/1027) * Rename config files and clarify their purposes [#969](https://github.com/commercialhaskell/stack/issues/969) * `~/.stack/stack.yaml` --> `~/.stack/config.yaml` * `~/.stack/global` --> `~/.stack/global-project` * `/etc/stack/config` --> `/etc/stack/config.yaml` * Old locations still supported, with deprecation warnings * New command "stack eval CODE", which evaluates to "stack exec ghc -- -e CODE". Other enhancements: * No longer install `git` on Windows [#1046](https://github.com/commercialhaskell/stack/issues/1046). You can still get this behavior by running the following yourself: `stack exec -- pacman -Sy --noconfirm git`. * Typing enter during --file-watch triggers a rebuild [#1023](https://github.com/commercialhaskell/stack/pull/1023) * Use Haddock's `--hyperlinked-source` (crosslinked source), if available [#1070](https://github.com/commercialhaskell/stack/pull/1070) * Use Stack-installed GHCs for `stack init --solver` [#1072](https://github.com/commercialhaskell/stack/issues/1072) * Experimental: Add `stack query` command [#1087](https://github.com/commercialhaskell/stack/issues/1087) * By default, Stack no longer rebuilds a package due to GHC options changes. This behavior can be tweaked with the `rebuild-ghc-options` setting. [#1089](https://github.com/commercialhaskell/stack/issues/1089) * By default, ghc-options are applied to all local packages, not just targets. This behavior can be tweaked with the `apply-ghc-options` setting. [#1089](https://github.com/commercialhaskell/stack/issues/1089) * Docker: download or override location of Stack executable to re-run in container [#974](https://github.com/commercialhaskell/stack/issues/974) * Docker: when Docker Engine is remote, don't run containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194) * Docker: `set-user` option to enable/disable running containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194) * Custom Setup.hs files are now precompiled instead of interpreted. This should be a major performance win for certain edge cases (biggest example: [building Cabal itself](https://github.com/commercialhaskell/stack/issues/1041)) while being either neutral or a minor slowdown for more common cases. * `stack test --coverage` now also generates a unified coverage report for multiple test-suites / packages. In the unified report, test-suites can contribute to the coverage of other packages. Bug fixes: * Ignore stack-built executables named `ghc` [#1052](https://github.com/commercialhaskell/stack/issues/1052) * Fix quoting of output failed command line arguments * Mark executable-only packages as installed when copied from cache [#1043](https://github.com/commercialhaskell/stack/pull/1043) * Canonicalize temporary directory paths [#1047](https://github.com/commercialhaskell/stack/pull/1047) * Put code page fix inside the build function itself [#1066](https://github.com/commercialhaskell/stack/issues/1066) * Add `explicit-setup-deps` option [#1110](https://github.com/commercialhaskell/stack/issues/1110), and change the default to the old behavior of using any package in the global and snapshot database [#1025](https://github.com/commercialhaskell/stack/issues/1025) * Precompiled cache checks full package IDs on Cabal < 1.22 [#1103](https://github.com/commercialhaskell/stack/issues/1103) * Pass -package-id to ghci [#867](https://github.com/commercialhaskell/stack/issues/867) * Ignore global packages when copying precompiled packages [#1146](https://github.com/commercialhaskell/stack/issues/1146) ## 0.1.5.0 - 2015-09-24 Major changes: * On Windows, we now use a full MSYS2 installation in place of the previous PortableGit. This gives you access to the pacman package manager for more easily installing libraries. * Support for custom GHC binary distributions [#530](https://github.com/commercialhaskell/stack/issues/530) * `ghc-variant` option in `stack.yaml` to specify the variant (also `--ghc-variant` command-line option) * `setup-info` in `stack.yaml`, to specify where to download custom binary distributions (also `--ghc-bindist` command-line option) * Note: On systems with libgmp4 (aka `libgmp.so.3`), such as CentOS 6, you may need to re-run `stack setup` due to the centos6 GHC binary distribution being treated like a variant * A new `--pvp-bounds` flag to the sdist and upload commands allows automatic adding of PVP upper and/or lower bounds to your dependencies Other enhancements: * Adapt to upcoming Cabal installed package identifier format change [#851](https://github.com/commercialhaskell/stack/issues/851) * `stack setup` takes a `--stack-setup-yaml` argument * `--file-watch` is more discerning about which files to rebuild for [#912](https://github.com/commercialhaskell/stack/issues/912) * `stack path` now supports `--global-pkg-db` and `--ghc-package-path` * `--reconfigure` flag [#914](https://github.com/commercialhaskell/stack/issues/914) [#946](https://github.com/commercialhaskell/stack/issues/946) * Cached data is written with a checksum of its structure [#889](https://github.com/commercialhaskell/stack/issues/889) * Fully removed `--optimizations` flag * Added `--cabal-verbose` flag * Added `--file-watch-poll` flag for polling instead of using filesystem events (useful for running tests in a Docker container while modifying code in the host environment. When code is injected into the container via a volume, the container won't propagate filesystem events). * Give a preemptive error message when `-prof` is given as a GHC option [#1015](https://github.com/commercialhaskell/stack/issues/1015) * Locking is now optional, and will be turned on by setting the `STACK_LOCK` environment variable to `true` [#950](https://github.com/commercialhaskell/stack/issues/950) * Create default `stack.yaml` with documentation comments and commented out options [#226](https://github.com/commercialhaskell/stack/issues/226) * Out of memory warning if Cabal exits with -9 [#947](https://github.com/commercialhaskell/stack/issues/947) Bug fixes: * Hacky workaround for optparse-applicative issue with `stack exec --help` [#806](https://github.com/commercialhaskell/stack/issues/806) * Build executables for local extra-deps [#920](https://github.com/commercialhaskell/stack/issues/920) * copyFile can't handle directories [#942](https://github.com/commercialhaskell/stack/pull/942) * Support for spaces in Haddock interface files [fpco/minghc#85](https://github.com/fpco/minghc/issues/85) * Temporarily building against a "shadowing" local package? [#992](https://github.com/commercialhaskell/stack/issues/992) * Fix `Setup.exe` name for `--upgrade-cabal` on Windows [#1002](https://github.com/commercialhaskell/stack/issues/1002) * Unlisted dependencies no longer trigger extraneous second build [#838](https://github.com/commercialhaskell/stack/issues/838) ## 0.1.4.1 - 2015-09-04 Fix stack's own Haddocks. No changes to functionality (only comments updated). ## 0.1.4.0 - 2015-09-04 Major changes: * You now have more control over how GHC versions are matched, e.g. "use exactly this version," "use the specified minor version, but allow patches," or "use the given minor version or any later minor in the given major release." The default has switched from allowing newer later minor versions to a specific minor version allowing patches.

# Build overview !!! warning This document should not be considered accurate until this warning is removed. This is a work-in-progress document covering the build process used by Stack. It was started following the Pantry rewrite work in Stack 2.1.1, and contains some significant changes/simplifications from how things used to work. This document will likely not fully be reflected in the behavior of Stack itself until late in the Stack 2.0 development cycle. ## Terminology * Project package: anything listed in `packages` in stack.yaml * Dependency: anything listed in extra-deps or a snapshot * Target: package and/or component listed on the command line to be built. Can be either project package or dependency. If none specified, automatically targets all project packages * Immutable package: a package which comes from Hackage, an archive, or a repository. In contrast to... * Mutable package: a package which comes from a local file path. The contents of such a package are assumed to mutate over time. * Write only database: a package database and set of executables for a given set of _immutable_ packages. Only packages from immutable sources and which depend exclusively on other immutable packages can be in this database. *NOTE* formerly this was the _snapshot database_. * Mutable database: a package database and set of executables for packages which are either mutable or depend on such mutable packages. Importantly, packages in this database can be unregister, replaced, etc, depending on what happens with the source packages. *NOTE* formerly this was the *local database*. Outdated terminology to be purged: * Wanted * Local * Snapshot package ## Inputs Stack pays attention to the following inputs: * Current working directory, used for finding the default `stack.yaml` file and resolving relative paths * The `STACK_YAML` environment variable * Command line arguments (CLI args), as will be referenced below Given these inputs, Stack attempts the following process when performing a build. ## Find the `stack.yaml` file * Check for a `--stack-yaml` CLI arg, and use that * Check for a `STACK_YAML` env var * Look for a `stack.yaml` in this directory or ancestor directories * Fall back to the default global project This file is parsed to provide the following config values: * `snapshot` (or, alternatively, `resolver`) (required key) * `compiler` (optional key) * `packages` (optional key, value defaults to `["."]`) * `extra-deps` (optional key, value defaults to `[]`) * `flags` (optional key, value defaults to `{}`) * `ghc-options` (optional key, value defaults to `{}`) `flags` and `ghc-options` break down into both _by name_ (applied to a specific package) and _general_ (general option `*` for flags is only available in CLI). ## Wanted compiler, dependencies, and project packages * If the `--snapshot` CLI is present, ignore the `snapshot` (or `resolver`) and `compiler` config values * Load up the indicated snapshot (either config value or CLI arg). This will provide: * A map from package name to package location, flags, GHC options, and if a package should be hidden. All package locations here are immutable. * A wanted compiler version, e.g. `ghc-8.6.5` * If the `--compiler` CLI arg is set, or the `compiler` config value is set (and `--snapshot` CLI arg is not set), ignore the wanted compiler from the snapshot and use the specified wanted compiler * Parse `extra-deps` into a `Map PackageName PackageLocation`, containing both mutable and immutable package locations. Parse `packages` into a `Map PackageName ProjectPackage`. * Ensure there are no duplicates between these two sets of packages * Delete any packages from the snapshot packages that appear in `packages` or `extra-deps` * Perform a left biased union between the immutable `extra-deps` values and the snapshot packages. Ignore any settings in the snapshot packages that have been replaced. * Apply the `flags` and `ghc-options` by name to these packages overwriting any previous values coming from a snapshot. If any values are specified but no matching package is found, it's an error. If a flag is not defined in the corresponding package cabal file, it's an error. * We are now left with the following: * A wanted compiler version * A map from package name to immutable packages with package config (flags, GHC options, hidden) * A map from package name to mutable packages as dependencies with package config * A map from package name to mutable packages as project packages with package config ## Get actual compiler Use the wanted compiler and various other Stack config values (not all listed here) to find the actual compiler, potentially installing it in the process. ## Global package sources With the actual compiler discovered, list out the packages available in its database and create a map from package name to version/GhcPkgId. Remove any packages from this map which are present in one of the other three maps mentioned above. ## Resolve targets Take the CLI args for targets as raw text values and turn them into actual targets. * Do a basic parse of the values into one of the following: * Package name * Package identifier * Package name + component * Directory * An empty target list is equivalent to listing the package names of all project packages * For any directories specified, find all project packages in that directory or subdirectories therefore and convert to those package names * For all package identifiers, ensure that either the package name does not exist in any of the three parsed maps from the "wanted compiler" step above, or that the package is present as an immutable dependency from Hackage. If so, create an immutable dependency entry with default flags, GHC options, and hidden status, and add this package to the set of immutable package dependencies. * For all package names, ensure the package is in one of the four maps we have, and if so add to either the dependency or project package target set. * For all package name + component, ensure that the package is a project package, and add that package + component to the set of project targets. * Ensure that no target has been specified multiple times. (*FIXME* Mihai states: I think we will need an extra consistency step for internal libraries. Sometimes stack needs to use the mangled name (`z-package-internallibname-z..`), sometimes the `package:internallibname` one. But I think this will become obvious when doing the code changes.) We now have an update four package maps, a new set of dependency targets, and a new set of project package targets (potentially with specific components). ## Apply named CLI flags Named CLI flags are applied to specific packages by updating the config in one of the four maps. If a flag is specified and no package is found, it's an error. Note that flag settings are added _on top of_ previous settings in this case, and does not replace them. That is, if previously we have `singleton (FlagName "foo") True` and now add `singleton (FlagName "bar") True`, both `foo` and `bar` will now be true. If any flags are specified but no matching package is found, it's an error. If a flag is not defined in the corresponding package cabal file, it's an error. ## Apply CLI GHC options CLI GHC options are applied as general GHC options according to `apply-ghc-options` setting. ## Apply general flags from CLI `--flag *:flagname[:bool]` specified on the CLI are applied to any project package which uses that flag name. ## Apply general GHC options General options are divided into the following categories: * `$locals` is deprecated, it's now a synonym for `$project` * `$project` applies to all project packages, not to any dependencies * `$targets` applies to all project packages that are targets, not to any dependencies or non-target project packages. This is the default option for `apply-ghc-options` * `$everything` applies to all packages in the source map excluding global packages These options get applied to any corresponding packages in the source map. If some GHC options already exist for such a package then they get prepended otherwise they get used as is. ## Determine snapshot hash Use some deterministic binary serialization and SHA256 thereof to get a hash of the following information: * Actual compiler (GHC version, path, *FIXME* probably some other unique info from GHC, I've heard that `ghc --info` gives you something) * Global database map * Immutable dependency map Motivation: Any package built from the immutable dependency map and installed in this database will never need to be rebuilt. !!! bug "To do" Caveat: do we need to take profiling settings into account here? How about Haddock status? ## Determine actual target components * Dependencies: "default" components (all libraries and executables) * Project packages: * If specific components named: only those, plus any libraries present * If no specific components, include the following: * All libraries, always * All executables, always * All test suites, _if_ `--test` specified on command line * All benchmarks, _if_ `--bench` specified on command line ## Construct build plan * Applied to every target (project package or dependency) * Apply flags, platform, and actual GHC version to resolve dependencies in any package analyzed * Include all library dependencies for all enabled components * Include all dependencies for tools used during building ('build tools') for all enabled components (using the fun backwards compat logic for `build-tools`) * Apply the logic recursively to come up with a full build plan * If a task depends exclusively on immutable packages, mark it as immutable. Otherwise, it's mutable. The former go into the snapshot database, the latter into the local database. We now have a set of tasks of packages/components to build, with full config information for each package, and dependencies that must be built first. !!! bug "To do" There's some logic to deal with cyclic dependencies between test suites and benchmarks, where a task can be broken up into individual components versus be kept as a single task. Need to document this better. Currently it's the "all in one" logic. ## Unregister local modified packages * For all mutable packages in the set of tasks, see if any files have changed since last successful build and, if so, unregister + delete their executables * For anything which depends on them directly or transitively, unregister + delete their executables ## Perform the tasks * Topological sort, find things which have no dependencies remaining * Check if already installed in the relevant database * Check package database * Check Stack specific "is installed" flags, necessary for non-library packages * For project packages, need to also check which components were built, if tests were run, if we need to rerun tests, etc * If all good: do nothing * Otherwise, for immutable tasks: check the precompiled cache for an identical package installation (same GHC, dependencies, etc). If present: copy that over, and we're done. * Otherwise, perform the build, register, write to the Stack specific "is installed" stuff, and (for immutable tasks) register to the precompiled cache "Perform the build" consists of: * Do a cabal configure, if needed * Build the desired components * For all test suites built, unless "no rerun tests" logic is on and we already ran the test, _or_ "no run tests" is on, run the test * For all benchmarks built, unless "no run benchmarks" is on, run the benchmark stack-3.7.1/doc/ChangeLog.md0000644000000000000000000054137015030022424013735 0ustar0000000000000000# Changelog ## v3.7.1 - 2025-06-28 **Changes since v3.5.1:** Other enhancements: * Bump to Hpack 0.38.1. * The `--extra-dep` option of Stack's `script` command now accepts a YAML value specifying any immutable extra-dep. Previously only an extra-dep in the package index that could be specified by a YAML string (for example, `acme-missiles-0.3@rev:0`) was accepted. Bug fixes: * `stack script --package ` now uses GHC's `-package-id` option to expose the installed package, rather than GHC's `-package` option. For packages with public sub-libraries, `-package ` can expose an installed package other than one listed by `ghc-pkg list `. * Work around `ghc-pkg` bug where, on Windows only, it cannot register a package into a package database that is also listed in the `GHC_PACKAGE_PATH` environment variable. In previous versions of Stack, this affected `stack script` when copying a pre-compiled package from another package database. * On Windows, when decompressing, and extracting tools, from archive files, Stack uses the system temporary directory, rather than the root of the destination drive, if the former is on the destination drive. ## v3.5.1 - 2025-03-29 **Changes since v3.3.1:** Behavior changes: * Stack will also warn (message S-8432) if there is any non-ISO/IEC 8859-1 (Latin-1) character in Stack's 'programs' path, as `hsc2hs` does not work if there is such a character in the path to its default template `template-hsc.h`. * Stack customizes setup using `Cabal`, so if a `setup-depends` field does not mention it as a dependency, Stack warns and adds the GHC boot package as a dependency. Previously, Stack would not do so but only warn that build errors were likely. Other enhancements: * Bump to Hpack 0.38.0. * In YAML configuration files, the `install-msys` key is introduced, to enable or disable the download and installation of Stack-supplied MSYS2 when necessary (subject to `skip-msys: false`). The default is the same as the `install-ghc` setting (including if that is set at the command line). Consequently, the default behaviour of Stack is unaffected. * Add the `stack config set install-msys` command to configure the `install-msys` option in YAML configuration files. * Option `allow-newer-deps` is no longer classified as experimental in documentation. * `stack sdist` and `stack upload` report the version of Cabal (the library) being used to check packages. * Add the `stack config build-files` command to generate (when applicable) a Cabal file from a package description in the Hpack format and/or a lock file for Stack's project-level configuration, without taking any other build steps. ## v3.3.1 - 2024-12-28 **Changes since v3.1.1:** Behavior changes: * Stack interprets consecutive line ends in the value of the `user-message` project-specific configuration option as a single blank line. Previously all line ends were interpreted as white space. * Stack no longer supports Docker versions before Docker 1.9.1 and, consequently, if a Docker container is not being run 'detached', its standard input channel will always be kept open. (Before Docker 1.9.1 the use of an interactive container could hang in certain circumstances.) * On Windows, Stack will always warn (message S-8432) if there is a space character in Stack's 'programs' path, as GHC 9.4.1 and later do not work if there is a space in the path to the `ghc` executable. S-8432 now presents as a warning and not an error. * Stack respects the `--no-run-tests` and `--no-run-benchmarks` flags when determining build actions. Previously Stack respected the flags when executing the run test suites or run benchmarks actions for each targeted project package. Other enhancements: * Consider GHC 9.10 to be a tested compiler and remove warnings. * Consider Cabal 3.12 to be a tested library and remove warnings. * Add flags `--run-tests` and `--run-benchmarks` (the existing defaults) to Stack's `build` command, which take precedence over the existing `no-run-tests` and `no-run-benchmarks` configuration options, respectively. * In configuration files, the `notify-if-no-run-tests` and `notify-if-no-run-benchmarks` keys are introduced, to allow the exisitng notification to be muted if unwanted. Bug fixes: * Stack's in-app messages refer to https://haskellstack.org as currently structured. (Most URLs in older Stack versions are redirected.) * Stack's `upgrade` command only treats the current running Stack executable as '`stack`' if the executable file is named `stack` or, on Windows, `stack.exe`. Previously only how it was invoked was considered. * `stack test --no-run-tests --dry-run` no longer reports that Stack would test project packages with test suites and `stack bench --no-run-benchmarks --dry-run` no longer reports that Stack would benchmark project packages with benchmarks. * `StackSetupShim` compiles with `Cabal >= 3.14.0.0`. ## v3.1.1 - 2024-07-28 Release notes: * The change in major version from 2.x to 3.1 marks the dropping of support for versions of GHC before 8.4, deprecated in Stack 2.15.1. **Changes since v2.15.7:** Behavior changes: * Stack uses the version of the Cabal package that comes with the specified version of GHC. Stack no longer supports such Cabal versions before 2.2, which came with versions of GHC before 8.4. Consequently, the `init` command will not try LTS Haskell before 12.0. * The `init` command initialises `stack.yaml` with a `snapshot` key rather than a `resolver` key. * After installing GHC or another tool, Stack deletes the archive file which provided the tool. * Remove hidden flag `--skip-intermediate-deps`, effectively deprecated since Stack 1.3.0, from `ghci` and `repl` commands. * The `haddock --haddock-for-hackage` command only seeks to create an archive of the `-docs` directory for build targets and if flags excluding the building of project packages are not set. * The predecessor of configuration option `package-index`, `package-indices` (deprecated in Stack 2.9.3) has been removed as an alternative option. * If a build target is a package identifier, and the package version is not in the snapshot or the package index, Stack will report an error when the target is parsed. Previously, if another version of the package was in the snapshot, Stack would construct the build plan with that other version or, if it was not, Stack would defer an error to the construction of the build plan. * The `list` command, with a specified snapshot and package, also reports the version of the package included indirectly in the snapshot (as a boot package of the compiler specified by the snapshot). * `stack build --flag *:[-]` now only applies the flag setting to packages for which the Cabal flag is defined, as opposed to all packages. * On Unix-like operating systems, drop support for `/etc/stack/config`, deprecated in Stack 0.1.6.0. * Drop support for, in the Stack root, directory `global` and file `stack.yaml`, both deprecated in Stack 0.1.6.0. Other enhancements: * Bump to Hpack 0.37.0. * In YAML configuration files, the `msys-environment` key is introduced to allow, on Windows, the MSYS2 environment to be specified. The default environment is still `MINGW64` on 64-bit Windows and `MINGW32` on 32-bit Windows. * In YAML configuration files, the `default-init-snapshot` key is introduced to allow a default snapshot to be specified for use with the `stack init` command, as if it had been specified at the command line. * Add flags `--haddock-executables`, `--haddock-tests` and `--haddock-benchmarks` to Stack's `build` command (including the `haddock` synonym for `build --haddock`) to enable also building Haddock documentation for executables, test suites and benchmarks. Due to a bug in Cabal (the library), Stack will ignore the flags with a warning for GHC versions before 9.4. * Add flag `--[no-]save-hackage-creds` to Stack's `upload` command, which takes precedence over the existing `save-hackage-creds` configuration option. * In YAML configuration files, the `global-hints-location` key is introduced to allow the location of the global hints YAML specification file to be specified. * By default, Hpack 0.20.0 or later will decline to overwrite a Cabal file that was modified manually. In YAML configuration files, the `hpack-force` key is introduced to allow Hpack to overwrite such a Cabal file. The corresponding `--hpack-force` flag is also added. * Add the `stack config set recommend-stack-upgrade` command to configure whether or not Stack should notify the user if it identifes a new version of Stack is available in YAML configuration files. * Add the `ls globals` command to list all global packages for the version of GHC specified by the snapshot. * Add `stack -h` (equivalent to `stack --help`). * In YAML configuration files, the `file-watch-hook` key is introduced to allow `--file-watch` post-processing to be customised with a executable or `sh` shell script. * Add flag `--[no-]allow-newer` to Stack's `build` command, which takes precedence over the existing `allow-newer` configuration option. Bug fixes: * The `config set snapshot` and `config set resolver` commands now respect the presence of a synoymous key. * The `config set` commands support existing keys only in the form `key: value` on a single line. The commands now recognise that a line `key:` does not have that form. * On Unix-like operating systems, the `test --coverage` command now finds package keys even for very long package names. * The Error S-6362 message now acknowledges when the wanted compiler has been specified at the command line. * Fix a regression, introduced in Stack 2.11.1, that caused the `script` command to parse an (otherwise ignored) project-level configuration file. * Stack no longer makes recommendations about a project-level configuration file when only a global configuration file is in use. * Fix a regression, introduced in Stack 2.15.7, that caused GHC 8.10.7 or earlier to fail to build a package with a `Custom` build type, if GHC option `-haddock` was specified. ## v2.15.7 - 2024-05-12 Release notes: * This release fixes potential bugs. * The hash that Stack uses to distinguish one build plan from another has changed for plans that set (as opposed to unset) manually Cabal flags for immutable dependencies. This will cause Stack to rebuild dependencies for such plans. **Changes since v2.15.5:** Major changes: * Stack 2.15.5 and earlier cannot build with Cabal (the library) version `3.12.0.0`. Stack can now build with that Cabal version. Behavior changes: * Stack's `StackSetupShim` executable, when called with `repl` and `stack-initial-build-steps`, no longer uses Cabal's `replHook` to apply `initialBuildSteps` but takes a more direct approach. Bug fixes: * Fix a regression introduced in Stack 2.15.1 that caused a 'no operation' `stack build` to be slower than previously. * The hashes that Stack uses to distinguish one build plan from another now include the Cabal flags for immutable dependencies set manually. Previously, in error, only such flags that were unset manually were included. ## v2.15.5 - 2024-03-28 Release notes: * This release fixes potential bugs. **Changes since v2.15.3:** Behavior changes: * Following the handover of the Stackage project to the Haskell Foundation, the default value of the `urls` key is `latest-snapshot: https://stackage-haddock.haskell.org/snapshots.json`. * Stack no longer includes the snapshot package database when compiling the setup executable for a package with `build-type: Configure`. ## v2.15.3 - 2024-03-07 Release notes: * With one exception, this release fixes bugs. **Changes since v2.15.1:** Behavior changes: * `stack path --global-config`, `--programs`, and `--local-bin` no longer set up Stack's environment. Bug fixes: * Due to a bug, Stack 2.15.1 did not support versions of GHC before 8.2. Stack now supports GHC versions from 8.0. * `--haddock-for-hackage` does not ignore `--haddock-arguments`. * On Windows, package locations that are Git repositories with submodules now work as intended. * The `ghc`, `runghc` and `runhaskell` commands accept `--package` values that are a list of package names or package identifiers separated by spaces and, in the case of package identifiers, in the same way as if they were specified as targets to `stack build`. ## v2.15.1 - 2024-02-09 Release notes: * After an upgrade from an earlier version of Stack, on first use only, Stack 2.15.1 may warn that it had trouble loading the CompilerPaths cache. * The hash used as a key for Stack's pre-compiled package cache has changed, following the dropping of support for Cabal versions older than `1.24.0.0`. **Changes since v2.13.1:** Behavior changes: * Stack does not leave `*.hi` or `*.o` files in the `setup-exe-src` directory of the Stack root, and deletes any corresponding to a `setup-.hs` or `setup-shim-.hs` file, to avoid GHC issue [#21250](https://gitlab.haskell.org/ghc/ghc/-/issues/21250). * If Stack's Nix integration is not enabled, Stack will notify the user if a `nix` executable is on the PATH. This usually indicates the Nix package manager is available. In YAML configuration files, the `notify-if-nix-on-path` key is introduced, to allow the notification to be muted if unwanted. * Drop support for Intero (end of life in November 2019). * `stack path --stack-root` no longer sets up Stack's environment and does not load Stack's configuration. * Stack no longer locks on configuration, so packages (remote and local) can be configured in parallel. This increases the effective concurrency of builds that before would use fewer threads. Reconsider your `--jobs` setting accordingly. See [#84](https://github.com/commercialhaskell/stack/issues/84). * Stack warns that its support for Cabal versions before `2.2.0.0` is deprecated and may be removed in the next version of Stack. Removal would mean that projects using snapshots earlier than `lts-12.0` or `nightly-2018-03-18` (GHC 8.4.1) might no longer build. See [#6377](https://github.com/commercialhaskell/stack/issues/6377). * If Stack's `--resolver` option is not specified, Stack's `unpack` command with a package name will seek to update the package index before seeking to download the most recent version of the package in the index. * If the version of Cabal (the library) provided with the specified GHC can copy specific components, Stack will copy only the components built and will not build all executable components at least once. Other enhancements: * Consider GHC 9.8 to be a tested compiler and remove warnings. * Stack can build packages with dependencies on public sub-libraries of other packages. * Add flag `--no-init` to Stack's `new` command to skip the initialisation of the newly-created project for use with Stack. * The HTML file paths produced at the end of `stack haddock` are printed on separate lines and without a trailing dot. * Add option of the form `--doctest-option=` to `stack build`, where `doctest` is a program recognised by versions of the Cabal library from `1.24.0.0`. * Experimental: Add flag `--haddock-for-hackage` to Stack's `build` command (including the `haddock` synonym for `build --haddock`) to enable building project packages with flags to generate Haddock documentation, and an archive file, suitable for upload to Hackage. The form of the Haddock documentation generated for other packages is unaffected. * Experimental: Add flag `--documentation` (`-d` for short) to Stack's `upload` command to allow uploading of documentation for packages to Hackage. * `stack new` no longer rejects project templates that specify a `package.yaml` in a subdirectory of the project directory. * Stack will notify the user if Stack has not been tested with the version of GHC that is being user or a version of Cabal (the library) that has been found. In YAML configuration files, the `notify-if-ghc-untested` and `notify-if-cabal-untested` keys are introduced, to allow the notification to be muted if unwanted. * The compiler version is included in Stack's build message (e.g. `stack> build (lib + exe + test) with ghc-9.6.4`). * Add flag `--candidate` to Stack's `unpack` command, to allow package candidates to be unpacked locally. * Stack will notify the user if a specified architecture value is unknown to Cabal (the library). In YAML configuration files, the `notify-if-arch-unknown` key is introduced, to allow the notification to be muted if unwanted. * Add option `--filter ` to Stack's `ls dependencies text` command to filter out an item from the results, if present. The item can be `$locals` for all project packages. * Add option `--snapshot` as synonym for `--resolver`. * Add the `config set snapshot` command, corresponding to the `config set resolver` command. Bug fixes: * Fix the `Curator` instance of `ToJSON`, as regards `expect-haddock-failure`. * Better error message if a `resolver:` or `snapshot:` value is, in error, a YAML number. * Stack accepts all package names that are, in fact, acceptable to Cabal. * Stack's `sdist` command can check packages with names that include non-ASCII characters. ## v2.13.1 - 2023-09-29 Release notes: * Further to the release notes for Stack 2.3.1, the `-static` suffix has been removed from the statically-linked Linux/x86_64 executables. * The executables for Linux/Aarch64 are now statically-linked. * Executables are now provided for macOS/AArch64. **Changes since v2.11.1:** Behavior changes: * Build artefacts are placed in `.stack-work/dist//` (hashed to a shorter path on Windows), rather than `.stack-work/dist//`. This allows build artifacts to be distinguished by GHC version. * By default, the `stack build` progress bar is capped to a length equal to the terminal width. * When building GHC from source, Stack no longer uses Hadrian's deprecated `--configure`\\`-c` flag and, instead, seeks to run GHC's Python `boot` and sh `configure` scripts, and ensure that the `happy` and `alex` executables are on the PATH. * When auto-detecting `--ghc-build` on Linux, the `musl` GHC build only is considered a possible GHC build if `libc.musl-x86_64.so.1` is found in `\lib` or `\lib64`. * No longer supports Cabal versions older than `1.24.0.0`. This means projects using snapshots earlier than `lts-7.0` or `nightly-2016-05-26` (GHC 8.0.1) will no longer build. GHC 8.0.1 comes with Haddock 2.17.2. * When unregistering many packages in a single step, Stack can now do that efficiently. Stack no longer uses GHC-supplied `ghc-pkg unregister` (which is, currently, slower). * `stack hpc report`, `stack list`, `stack templates` and `stack uninstall` output their information to the standard output stream rather than to the standard error stream. Logging is still to the standard error stream. * `stack upgrade` no longer assumes that binary upgrade is not supported on a AArch64 machine architecture. Other enhancements: * Consider GHC 9.6 to be a tested compiler and remove warnings. * Consider Cabal 3.10 to be a tested library and remove warnings. * Bump to Hpack 0.36.0. * Depend on `pantry-0.9.2`, for support for long filenames and directory names in archives created by `git archive`. * Avoid the duplicate resolving of usage files when parsing `*.hi` files into a set of modules and a collection of resolved usage files. See [#6123](https://github.com/commercialhaskell/stack/pull/6123). * Add composable component type flags `--exes`, `--tests` and `--benchmarks` to Stack's `ide targets` command, to list only those components. * `stack --verbose` excludes lengthy information about build plan construction in the debug output by default. The new `stack --[no-]plan-in-log` flag enables or disables the inclusion of the information in the debug output. * In YAML configuration files, the `casa` key is introduced, which takes precedence over the existing `casa-repo-prefix` key. The latter is deprecated. The new key also allows Stack's use of a Casa (content-addressable storage archive) server to be disabled and the maximum number of keys per request to be configured. The default Casa prefix references https://casa.stackage.org, instead of https://casa.fpcomplete.com. * Add option `--progress-bar=` to Stack's `build` command to configure the format of the progress bar, where `` is one of `none`, `count-only` (only the package count), `capped` (capped to a length equal to the terminal width) and `full` (the previous format). Bug fixes: * Restore `stack sdist --pvp-bounds lower` (broken with Stack 2.9.1). * Restore building of Stack with Cabal flag `disable-git-info` (broken with Stack 2.11.1). * With `stack hoogle`, avoid the message `Minimum version is hoogle-5.0. Found acceptable hoogle- in your index, requiring its installation.` when a `hoogle` executable has already been found on the `PATH`. * Stack's sanity check on a selected GHC now passes GHC flag `-hide-all-packages`, stopping GHC from looking for a package environment in default locations. * Restore Stack script files without extensions (broken with Stack 2.11.1). * Restore message suffix `due to warnings` with `dump-logs: warning` (broken with Stack 2.11.1). * On Windows, the `local-programs-path` directory can now be on a different drive to the system temporary directory and MSYS2 will still be installed. ## v2.11.1 - 2023-05-18 **Changes since v2.9.3:** Behavior changes: * Add flag `--[no-]-only-local-bin` to Stack's `upgrade` command for a binary upgrade. If the Stack executable is `my-stack`, the default is `my-stack upgrade --only-local-bin` where previously it was, effectively, `my-stack upgrade --no-only-local-bin`. If the Stack executable is `stack`, the default is `stack upgrade --no-only-local-bin`, the same behaviour as previously. * Use `$XDG_CACHE_HOME/stack/ghci-script`, rather than `/haskell-stack-ghci` (where `` is the directory yielded by the `temporary` package's `System.IO.Temp.getCanonicalTemporaryDirectory`), as the base location for GHCi script files generated by `stack ghci` or `stack repl`. See [#5203](https://github.com/commercialhaskell/stack/issues/5203) * Drop support for `Cabal` versions before 1.22 and, consequently, GHC versions before 7.10. * `stack ghci` and `stack repl` now take into account the values of `default-language` fields in Cabal files, like they take into account the values of `default-extensions` fields. * Removed `--ghc-paths`, `--global-stack-root` and `--local-bin-path` flags for `stack path`, deprecated in Stack 1.1.0 in favour of `--programs`, `--stack-root` and `local-bin` respectively. * On Windows, `stack upgrade` always renames the file of the running Stack executable (adding extension `.old`) before attempting to write to the original file name. * On Windows, `stack upgrade` does not offer `sudo` command alternatives if attempting to write to the original file name of the running Stack exectuable results in a 'Permission' error. * On Linux, Stack's `setup` command now distinguishes GHC build `tinfo6-libc6-pre232` from existing `tinfo6`. The former refers to systems where the version of `libc6` (the GNU C Library) is not compatible with version 2.32. `tinfo6-libc6-pre232` is now a possible value for the `ghc-build` configuration option. Other enhancements: * Add options of the form `--PROG-option=` to `stack build`, where `PROG` is a program recognised by the Cabal library and one of `alex`, `ar`, `c2hs`, `cpphs`, `gcc`, `greencard`, `happy`, `hsc2hs`, `hscolour`, `ld`, `pkg-config`, `strip` and `tar`. If Cabal uses the program during the configuration step, the argument is passed to it. * By default all `--PROG-option` options are applied to all project packages. This behaviour can be changed with new configuration option `apply-prog-options`. * Add flag `--[no-]use-root` to `stack script` (default disabled). Used with `--compile` or `--optimize`, when enabled all compilation outputs (including the executable) are written to a script-specific location in the `scripts` directory of the Stack root rather than the script's directory, avoiding clutter of the latter directory. * Better error message if the value of the `STACK_WORK` environment variable or `--work-dir` option is not a valid relative path. * Stack will use the value of the `GH_TOKEN`, or `GITHUB_TOKEN`, environment variable as credentials to authenticate its GitHub REST API requests. * `stack uninstall` also shows how to uninstall Stack-supplied tools. Bug fixes: * Fix incorrect warning if `allow-newer-deps` are specified but `allow-newer` is `false`. See [#6068](https://github.com/commercialhaskell/stack/issues/6086). * `stack build` with `--file-watch` or `--file-watch-poll` outputs 'pretty' error messages, as intended. See [#5978](https://github.com/commercialhaskell/stack/issues/5978). * `stack build` unregisters any project packages for the sub libraries of a project package that is to be unregistered. See [#6046](https://github.com/commercialhaskell/stack/issues/6046). * The warning that sublibrary dependency is not supported is no longer triggered by internal libraries. ## v2.9.3.1 - 2023-06-22 Hackage-only release of the `stack` package: * Supports building against snapshot Stackage LTS Haskell 21.0 (GHC 9.4.5), without extra-deps. * Supports build with `persistent-2.14.5.0`, using CPP directives. * Supports build with `unix-compat-0.7`, by removing reliance on the module `System.PosixCompat.User` removed in that package. * Includes `cabal.project` and `cabal.config` files in the package. ## v2.9.3 - 2022-12-16 **Changes since v2.9.1:** Behavior changes: * In YAML configuration files, the `package-index` key is introduced which takes precedence over the existing `package-indices` key. The latter is deprecated. * In YAML configuration files, the `hackage-security` key of the `package-index` key or the `package-indices` item can be omitted, and the Hackage Security configuration for the item will default to that for the official Hackage server. See [#5870](https://github.com/commercialhaskell/stack/issues/5870). * Add the `stack config set package-index download-prefix` command to set the location of Stack's package index in YAML configuration files. * `stack setup` with the `--no-install-ghc` flag warns that the flag and the command are inconsistent and now takes no action. Previously the flag was silently ignored. * To support the Haskell Foundation's [Haskell Error Index](https://errors.haskell.org/) initiative, all Stack error messages generated by Stack itself begin with an unique code in the form `[S-nnnn]`, where `nnnn` is a four-digit number. * Test suite executables that seek input on the standard input stream (`stdin`) will not throw an exception. Previously, they would thow an exception, consistent with Cabal's 'exitcode-stdio-1.0' test suite interface specification. Pass the flag `--no-tests-allow-stdin` to `stack build` to enforce Cabal's specification. See [#5897](https://github.com/commercialhaskell/stack/issues/5897) Other enhancements: * Help documentation for `stack upgrade` warns that if GHCup is used to install Stack, only GHCup should be used to upgrade Stack. That is because GHCup uses an executable named `stack` to manage versions of Stack, that Stack will likely overwrite on upgrade. * Add `stack ls dependencies cabal` command, which lists dependencies in the format of exact Cabal constraints. * Add `STACK_XDG` environment variable to use the XDG Base Directory Specification for the Stack root and Stack's global YAML configuration file, if the Stack root location is not set on the command line or by using the `STACK_ROOT` environment variable. * Add `stack path --global-config`, to yield the full path of Stack's user-specific global YAML configuration file (`config.yaml`). * Experimental: Add option `allow-newer-deps`, which allows users to specify a subset of dependencies for which version bounds should be ignored (`allow-newer-deps: ['foo', 'bar']`). This key has no effect unless `allow-newer` is enabled. Bug fixes: * Fix ambiguous module name `Distribution.PackageDescription`, if compiling `StackSetupShim` with `Cabal-syntax-3.8.1.0` in package database. See [#5886](https://github.com/commercialhaskell/stack/pull/5886). * In YAML configuration files, if the `package-indices` key (or the `hackage-security` key of its item) is omitted, the expiration of timestamps is now ignored, as intended. See Pantry [#63](https://github.com/commercialhaskell/pantry/pull/63) ## v2.9.1 - 2022-09-19 **Changes since v2.7.5:** Release notes: * After an upgrade from an earlier version of Stack, on first use only, Stack 2.9.1 may warn that it had trouble loading the CompilerPaths cache. * The support from the Stack team for executable releases now includes Linux/AArch64 and is limited to: * Linux 64-bit/x86_64 (statically-linked) * Linux AArch64 (dynamically-linked) * macOS x86_64 * Windows 64-bit/x86_64 Behavior changes: * `stack build --coverage` will generate a unified coverage report, even if there is only one `*.tix` file, in case a package has tested the library of another package that has not tested its own library. See [#5713](https://github.com/commercialhaskell/stack/issues/5713) * `stack --verbose` no longer includes the lengthy raw snapshot layer (rsl) in the debug output by default. The new `stack --[no-]rsl-in-log` flag enables or disables the inclusion of the rsl in the debug output. Other enhancements: * Consider GHC 9.2 and 9.4 to be tested compilers and remove warnings. * Consider Cabal 3.6 and 3.8 to be a tested libraries and remove warnings. * Bump to Hpack 0.35.0. * On Windows, the installer now sets `DisplayVersion` in the registry, enabling tools like `winget` to properly read the version number. * Adds flag `--script-no-run-compile` (disabled by default) that uses the `--no-run` option with `stack script` (and forces the `--compile` option). This enables a command like `stack --script-no-run-compile Script.hs` to behave like `stack script --no-run --compile -- Script.hs` but without having to list all the `` in the Stack interpreter options comment in `Script.hs` on the command line. That may help test that scripts compile in CI (continuous integration). See [#5755](https://github.com/commercialhaskell/stack/issues/5755) * Fuller help is provided at the command line if a subcommand is missing (for example, `stack ls` now yields the equivalent of `stack ls --help`). See [#809](https://github.com/commercialhaskell/stack/issues/809) * Add build option `--cabal-verbosity=VERBOSITY` to specify the Cabal verbosity level (the option accepts Cabal's numerical and extended syntax). See [#1369](https://github.com/commercialhaskell/stack/issues/809) * Add the possibility of a `sh` script to customise fully GHC installation. See [#5585](https://github.com/commercialhaskell/stack/pull/5585) * `tools` subcommand added to `stack ls`, to list stack's installed tools. * `stack uninstall` shows how to uninstall Stack. * `--ghc-variant` accepts `int-native` as a variant. Bug fixes: * Fix `stack clean --full`, so that the files to be deleted are not in use. See [#5714](https://github.com/commercialhaskell/stack/issues/5714) * Fix an inconsistency in the pretty formatting of the output of `stack build --coverage` * Fix repeated warning about missing parameters when using `stack new` * Include `pantry-0.5.6`: Remove operational and mirror keys from bootstrap key set [#53](https://github.com/commercialhaskell/pantry/pull/53) * Pass any CPP options specified via `cpp-options:` in the Cabal file to GHCi using GHC's `-optP` flag. See [#5608](https://github.com/commercialhaskell/stack/pull/5608) * On Unix-like operating systems, respect the `with-gcc` option when installing GHC. See [#5609](https://github.com/commercialhaskell/stack/pull/5609) * Fixed logic in `get_isa()` in `get-stack.sh` to exclude systems that don't have x86 in their `uname -m` output. See [5792](https://github.com/commercialhaskell/stack/issues/5792). * Fixed output of `stack ls snapshots local` on Windows, to behave like that on Unix-like operating systems. * Fix non-deterministic test failures when executing a test suite for a multi-project repository with parallelism enabled. See [#5024](https://github.com/commercialhaskell/stack/issues/5024) ## v2.7.5 - 2022-03-06 **Changes since v2.7.3:** Behavior changes: * Cloning git repositories isn't per sub-directory anymore, see [#5411](https://github.com/commercialhaskell/stack/issues/5411) Other enhancements: * `stack setup` supports installing GHC for macOS/AArch64 (M1) * `stack upload` supports authentication with a Hackage API key (via `HACKAGE_KEY` environment variable). Bug fixes: * Ensure that `extra-path` works for case-insensitive `PATH`s on Windows. See [rio#237](https://github.com/commercialhaskell/rio/pull/237) * Fix handling of overwritten `ghc` and `ghc-pkg` locations. [#5597](https://github.com/commercialhaskell/stack/pull/5597) * Fix failure to find package when a dependency is shared between projects. [#5680](https://github.com/commercialhaskell/stack/issues/5680) * `stack ghci` now uses package flags in `stack.yaml` [#5434](https://github.com/commercialhaskell/stack/issues/5434) ## v2.7.3 - 2021-07-20 **Changes since v2.7.1:** Other enhancements: * `stack upgrade` will download from `haskellstack.org` before trying `github.com`. See [#5288](https://github.com/commercialhaskell/stack/issues/5288) * `stack upgrade` makes less assumptions about archive format. See [#5288](https://github.com/commercialhaskell/stack/issues/5288) * Add a `--no-run` flag to the `script` command when compiling. Bug fixes: * GHC source builds work properly for recent GHC versions again. See [#5528](https://github.com/commercialhaskell/stack/issues/5528) * `stack setup` always looks for the unpacked directory name to support different tar file naming conventions. See [#5545](https://github.com/commercialhaskell/stack/issues/5545) * Bump `pantry` version for better OS support. See [pantry#33](https://github.com/commercialhaskell/pantry/issues/33) * When building the sanity check for a new GHC install, make sure to clear `GHC_PACKAGE_PATH`. * Specifying GHC RTS flags in the `stack.yaml` no longer fails with an error. [#5568](https://github.com/commercialhaskell/stack/pull/5568) * `stack setup` will look in sandboxed directories for executables, not relying on `findExecutables. See [GHC issue 20074](https://gitlab.haskell.org/ghc/ghc/-/issues/20074) * Track changes to `setup-config` properly to avoid reconfiguring on every change. See [#5578](https://github.com/commercialhaskell/stack/issues/5578) ## v2.7.1 - 2021-05-07 **Changes since v2.5.1.1:** Behavior changes: * `stack repl` now always warns about GHCi problems with loading multiple packages. It also sets now proper working directory when invoked with one package. See [#5421](https://github.com/commercialhaskell/stack/issues/5421) * `custom-setup` dependencies are now properly initialized for `stack dist`. This makes `explicit-setup-deps` no longer required and that option was removed. See [#4006](https://github.com/commercialhaskell/stack/issues/4006) Other enhancements: * Consider GHC 9.0 to be a tested compiler and remove warnings. * Consider Cabal 3.6 to be a tested library and remove warnings. * Nix integration now passes `ghcVersion` (in addition to existing `ghc`) to `shell-file` as an identifier that can be looked up in a compiler attribute set. * Nix integration now allows Nix integration if the user is ready in nix-shell. This gets rid of "In Nix shell but reExecL is False" error. * `stack list` is a new command to list package versions in a snapshot. See [#5431](https://github.com/commercialhaskell/stack/pull/5431) * `custom-preprocessor-extensions` is a new configuration option for allowing Stack to be aware of any custom preprocessors you have added to `Setup.hs`. See [#3491](https://github.com/commercialhaskell/stack/issues/3491) * Added `--candidate` flag to `upload` command to upload a package candidate rather than publishing the package. * Error output using `--no-interleaved-output` no longer prepends indenting whitespace. This allows emacs compilation-mode and vim quickfix to locate and track errors. See [#5523](https://github.com/commercialhaskell/stack/pull/5523) Bug fixes: * `stack new` now supports branches other than `master` as default for GitHub repositories. See [#5422](https://github.com/commercialhaskell/stack/issues/5422) * Ignore all errors from `hi-file-parser`. See [#5445](https://github.com/commercialhaskell/stack/issues/5445) and [#5486](https://github.com/commercialhaskell/stack/issues/5486). * Support basic auth in package-indices. See [#5509](https://github.com/commercialhaskell/stack/issues/5509). * Add support for parsing `.hi`. files from GHC 8.10 and 9.0. See [hi-file-parser#2](https://github.com/commercialhaskell/hi-file-parser/pull/2). ## v2.5.1.1 - 2020-12-09 Hackage-only release: * Support build with persistent-2.11.x and optparse-applicative-0.16.x ## v2.5.1 - 2020-10-15 **Changes since v2.3.3** Major changes: * Add the `snapshot-location-base` yaml configuration option, which allows to override the default location of snapshot configuration files. This option affects how snapshot synonyms (LTS/Nightly) are expanded to URLs by the `pantry` library. * `docker-network` configuration key added to override docker `--net` arg Behavior changes: * File watching now takes into account specified targets, old behavior could be restored using the new flag `--watch-all` [#5310](https://github.com/commercialhaskell/stack/issues/5310) Other enhancements: * The output of `stack ls dependencies json` now includes keys `sha256` and `size` for dependencies of `type` `archive` in `location`. [#5280](https://github.com/commercialhaskell/stack/issues/5280) * Build failures now show a hint to scroll up to the corresponding section [#5279](https://github.com/commercialhaskell/stack/issues/5279) * Customisable output styles (see `stack --help` and the `--stack-colors` option, and `stack ls stack-colors --help`) now include `info`, `debug`, `other-level`, `secondary` and `highlight`, used with verbose output. Bug fixes: * Fix `stack test --coverage` when using Cabal 3 * `stack new` now generates PascalCase'd module name correctly. [#5376](https://github.com/commercialhaskell/stack/issues/5376) * Connection issues to Casa server no longer cause builds to failure. Casa acts only as an optimizing cache layer, not a critical piece of infrastructure. * Fix modified time busting caches by always calculating sha256 digest during the build process. [#5125](https://github.com/commercialhaskell/stack/issues/5125) ## v2.3.3 - 2020-08-06 **Changes since v2.3.1** Other enhancements: * Add the `stack-developer-mode` flag Bug fixes: * When using the `STACK_YAML` env var with Docker, make the path absolute. * Fix the problem of `stack repl foo:test:bar` failing without a project build before that. See [#5213](https://github.com/commercialhaskell/stack/issues/5213) * Fix `stack sdist` introducing unnecessary sublibrary syntax when using pvp-bounds. See [#5289](https://github.com/commercialhaskell/stack/issues/5289) ## v2.3.1 - 2020-04-29 Release notes: * We have reduced the number of platforms that we support with executable releases. The reason behind this is that we've been slowed down in our release process until now with issues trying to build executables for less common platforms. In order to make sure we can address issues more quickly (like supporting new GHC versions), we're limiting support from the Stack team to: * Linux 64-bit/x86_64 (statically-linked) * macOS x86_64 * Windows 64-bit/x86_64 If others want to provide additional executables, we will definitely be happy for the support. But since our CI system is currently able to produce these three executables only, that's what we will be providing with the next release. * Since we no longer have dynamically-linked Linux executables, we are removing the `-static` suffix from the static Linux/x86_64 executables. If you have scripts to download the latest stable Linux/x86_64 executable, update them to use `linux-x86_64` instead of `linux-x86_64-static` (if you are already using the former, nothing needs to change). For this release, both are supported, but the next release will no longer have the `-static` variant. * We are also deprecating the download links at https://stackage.org/stack. See this page for the current installation instructions: https://docs.haskellstack.org/en/stable/install_and_upgrade/. * These are the canonical locations to download the latest stable binaries from, and will continue to be supported going forward: * Linux 64-bit/x86_64 (static): https://get.haskellstack.org/stable/linux-x86_64.tar.gz * macOS x86_64: https://get.haskellstack.org/stable/osx-x86_64.tar.gz * Windows 64-bit/x86_64: https://get.haskellstack.org/stable/windows-x86_64.zip As always, binaries for specific versions are available from the GitHub releases: https://github.com/commercialhaskell/stack/releases. **Changes since v2.1.3.1** Major changes: * `setup-info-locations` yaml configuration now allows overwriting the default locations of `stack-setup-2.yaml`. [#5031](https://github.com/commercialhaskell/stack/pull/5031) [#2983](https://github.com/commercialhaskell/stack/issues/2983) [#2913](https://github.com/commercialhaskell/stack/issues/2913) * The `setup-info` configuration key now allows overwriting parts of the default `setup-info` * The `--setup-info-yaml` command line flag now may be used in all Stack commands such as `stack build`, and not only in `stack setup` * The `--setup-info-yaml` may specify multiple locations for `stack-setup.yaml` files. * The `stack upload` can read first reads environment Variable `$HACKAGE_USERNAME` and `$HACKAGE_PASSWORD` if they are missing only then asks for `username` or `password` * Fully remove GHCJS support. * Remove the `freeze` command. It has been replaced by lock files. Behavior changes: * Remove the deprecated `--stack-setup-yaml` command line argument in favor of `--setup-info-yaml`. See [#2647](https://github.com/commercialhaskell/stack/issues/2647) * We now recommend checking in generated Cabal files for repos. When generating lock files for extra-deps that only include `package.yaml` files, a deprecation warning will be generated. Also, those packages will no longer be included in the generated lock files. See [#5210](https://github.com/commercialhaskell/stack/issues/5210). Other enhancements: * Add `build-output-timestamps` flag in yaml. Setting it to true prefixes each build log output line with a timestamp. * Show warning about `local-programs-path` with spaces on windows when running scripts. See [#5013](https://github.com/commercialhaskell/stack/pull/5013) * Add `ls dependencies json` which will print dependencies as JSON. `ls dependencies --tree` is now `ls dependencies tree`. See [#4424](https://github.com/commercialhaskell/stack/pull/4424) * Remove warning for using Stack with GHC 8.8-8.10, and Cabal 3.0-3.2. * Allow relative paths in `--setup-info-yaml` and tool paths [#3394](https://github.com/commercialhaskell/stack/issues/3394) * Added the `--only-locals` flag. See [#5272](https://github.com/commercialhaskell/stack/issues/5272) Bug fixes: * Upgrade `pantry`: module mapping insertions into the database are now atomic. Previously, if you SIGTERMed at the wrong time while running a script, you could end up with an inconsistent database state. * `--resolver global` doesn't retrieve snapshots list from the internet because doesn't need it. See [#5103](https://github.com/commercialhaskell/stack/issues/5103) * Fix using relative links in haddocks output. See [#4971](https://github.com/commercialhaskell/stack/issues/4971). * Do not include generated Cabal file information in lock files. See [#5045](https://github.com/commercialhaskell/stack/issues/5045). * Use proper Hoogle executable path when installed automatically. See [#4905](https://github.com/commercialhaskell/stack/issues/4905) * Fix GHC version for batched package unregistration. See [#4951](https://github.com/commercialhaskell/stack/issues/4951) * Use Hoogle from the snapshot used and not the latest version. See [#4905](https://github.com/commercialhaskell/stack/issues/4905) * Resolve "'stty' is not recognized". See [#4901](https://github.com/commercialhaskell/stack/issues/4901) * Fix missing reconfigure check causing errors when a package gets used in multiple projects. See [#5147](https://github.com/commercialhaskell/stack/issues/5147) ## v2.1.3.1 - 2019-07-16 Hackage-only release: * Support persistent-template-2.7.x * Support rio-0.1.11.0 * Add `stack.yaml` back to hackage sdist, and add `snapshot.yaml` ## v2.1.3 - 2019-07-13 **Changes since v2.1.1** Behavior changes: * Disable WAL mode for SQLite3 databases, to improve compatibility with some platforms and filesystems. See [#4876](https://github.com/commercialhaskell/stack/issues/4876). * By default, do not perform expiry checks in Hackage Security. See [#4928](https://github.com/commercialhaskell/stack/issues/4928). Other enhancements: * Do not rerun expected test failures. This is mostly a change that will only affect the Stackage Curator use case, but there is now an additional message letting the user know when a previously-failed test case is being rerun. * Move configure information for project packages back to .stack-work to improve caching. See [#4893](https://github.com/commercialhaskell/stack/issues/4893). Bug fixes: * Fix to allow dependencies on specific versions of local git repositories. See [#4862](https://github.com/commercialhaskell/stack/pull/4862) * Allow Stack commands to be run in Nix mode without having a project file available. See [#4854](https://github.com/commercialhaskell/stack/issues/4864). * Removes dependency on gnu-tar for OSX and Linux environment. The `--force-local` option was required only for windows environment. * Properly wait for the `tar` subprocess to complete before returning, thereby avoiding a SIGTERM screwing up GHC installation. See [#4888](https://github.com/commercialhaskell/stack/issues/4888). * Use package complete locations from lock files when resolving dependencies in `extra-deps`. See [#4887](https://github.com/commercialhaskell/stack/issues/4887). * Set the `HASKELL_DIST_DIR` environment to a proper package dist directory so `doctest` is able to load modules autogenerated by Cabal. * Expose package library when running tests. * Fix support for non-ASCII module names. See [#4938](https://github.com/commercialhaskell/stack/issues/4938) Other changes: * Rename `pantry-tmp` package back to `pantry`, now that we have gained maintainership (which had been used by someone else for a candidate-only test that made it look like the name was free but prevented uploading a real package). ## v2.1.1.1 - 2019-06-14 Hackage-only release that removes `stack.yaml` from the sdist. This is because `stack.yaml` now defines a multi-package project, whereas Hackage works on the basis on individual packages (see [#4860](https://github.com/commercialhaskell/stack/issues/4860)) If building a `stack` executable for distribution, please download the source code from https://github.com/commercialhaskell/stack/releases/tag/v2.1.1 and build it using Stack itself in order to ensure identical behaviour to official binaries. This package on Hackage is provided for convenience and bootstrapping purposes. ## v2.1.1 - 2019-06-13 The Stack 2 release represents a series of significant changes to how Stack works internally. For the vast majority of cases, these changes are backwards compatible, in that existing projects will continue to build in the same way with Stack 2 as they did with Stack 1. The large version bump is due to the fundamental internal changes to cache handling, database storage (using SQLite in place of binary files), implicit snapshots (which greatly improve the precompiled cache), and moving to Pantry. We have also removed some less used features, as listed below. **Changes since v1.9.3** Major changes: * Switch over to pantry for managing packages. This is a major change to Stack's internals, and affects user-visible behavior in a few places. Some highlights: * Drop support for multiple package indices and legacy `00-index.tar` style indices. See [#4137](https://github.com/commercialhaskell/stack/issues/4137). * Support for archives and repos in values of the `packages` key has been removed. Instead, you must use the `extra-deps` key for such dependencies. `packages` now only supports local filepaths. * Add support for Git repositories containing (recursive) submodules. * Addition of new configuration options for specifying a "pantry tree" key, which provides more reproducibility around builds, and (in the future) will be used for more efficient package content downloads. You can also specify package name and version for more efficient config parsing. * __NOTE__ The new `stack freeze` command provides support for automatically generating this additional information. * Package contents and metadata are stored in an SQLite database in place of files on the filesystem. The `pantry` library can be used for interacting with these contents. * Internally, Stack has changed many datatypes, including moving to Cabal's definition of many data types. As a result of such changes, existing cache files will in general be invalidated, resulting in Stack needing to rebuild many previously cached builds in the new version. Sorry :(. * A new command, `stack freeze` has been added which outputs project and snapshot definitions with dependencies pinned to their exact versions. * The `ignore-revision-mismatch` setting is no longer needed, and has been removed. * Overriding GHC boot packages results in any other GHC boot packages depending on it being no longer available as a dependency, such packages need to be added explicitly when needed. See [#4510] (https://github.com/commercialhaskell/stack/issues/4510). * Cabal solver integration was not updated to support newer `cabal-install` versions so `stack solver` command was removed as well as a related option `--solver` from `stack new` and `stack init`. * Upgrade to Cabal 2.4 * Note that, in this process, the behavior of file globbing has been modified to match that of Cabal. In particular, this means that for Cabal spec versions less than 2.4, `*.txt` will match `foo.txt`, but not `foo.2.txt`. * Remove the `stack image` command. With the advent of Docker multistage builds, this functionality is no longer useful. For an example, please see [Building Haskell Apps with Docker](https://www.fpcomplete.com/blog/2017/12/building-haskell-apps-with-docker). * Experimental: Support building GHC from source * Stack now supports building and installing GHC from source. The built GHC is uniquely identified by a commit id and an Hadrian "flavour" (Hadrian is the newer GHC build system), hence `compiler` can be set to use a GHC built from source with `ghc-git-COMMIT-FLAVOUR` * `stack.yaml` now supports a `configure-options`, which are passed directly to the `configure` step in the Cabal build process. See [#1438](https://github.com/commercialhaskell/stack/issues/1438) * Remove support for building GHCJS itself. Future releases of Stack may remove GHCJS support entirely. * Support for lock files for pinning exact project dependency versions Behavior changes: * `stack.yaml` now supports `snapshot`: a synonym for `resolver`. See [#4256](https://github.com/commercialhaskell/stack/issues/4256) * `stack script` now passes `-i -idir` in to the `ghc` invocation. This makes it so that the script can import local modules, and fixes an issue where `.hs` files in the current directory could affect interpretation of the script. See [#4538](https://github.com/commercialhaskell/stack/pull/4538) * When using `stack script`, custom snapshot files will be resolved relative to the directory containing the script. * Remove the deprecated `--upgrade-cabal` flag to `stack setup`. * Support the `drop-packages` key in `stack.yaml` * Remove the GPG signing code during uploads. The GPG signatures have never been used yet, and there are no plans to implement signature verification. * Remove the `--plain` option for the `exec` family of commands * Always use the `--exact-configuration` Cabal configuration option when building (should mostly be a non-user-visible enhancement). * No longer supports Cabal versions older than `1.19.2`. This means projects using snapshots earlier than `lts-3.0` or `nightly-2015-05-05` will no longer build. * Remove the `stack docker cleanup` command. Docker itself now has [`docker image prune`](https://docs.docker.com/engine/reference/commandline/image_prune/) and [`docker container prune`](https://docs.docker.com/engine/reference/commandline/container_prune/), which you can use instead. * Interleaved output is now turned on by default, see [#4702](https://github.com/commercialhaskell/stack/issues/4702). In addition, the `packagename> ` prefix is no longer included in interleaved mode when only building a single target. * The `-fhide-source-paths` GHC option is now enabled by default and can be disabled via the `hide-source-paths` configuration option in `stack.yaml`. See [#3784](https://github.com/commercialhaskell/stack/issues/3784) * Stack will reconfigure a package if you modify your `PATH` environment variable. See [#3138](https://github.com/commercialhaskell/stack/issues/3138). * For GHC 8.4 and later, disable the "shadowed dependencies" workaround. This means that Stack will no longer have to force reconfigures as often. See [#3554](https://github.com/commercialhaskell/stack/issues/3554). * When building a package, Stack takes a lock on the dist directory in use to avoid multiple runs of Stack from trampling each others' files. See [#2730](https://github.com/commercialhaskell/stack/issues/2730). * Stack will check occasionally if there is a new version available and prompt the user to upgrade. This will not incur any additional network traffic, as it will piggy-back on the existing Hackage index updates. You can set `recommend-stack-upgrade: false` to bypass this. See [#1681](https://github.com/commercialhaskell/stack/issues/1681). * `stack list-dependencies` has been removed in favour of `stack ls dependencies`. * The new default for `--docker-auto-pull` is enabled. See [#3332](https://github.com/commercialhaskell/stack/issues/3332). Other enhancements: * Support MX Linux in get-stack.sh. Fixes [#4769](https://github.com/commercialhaskell/stack/issues/4769). * Defer loading up of files for project packages. This allows us to get plan construction errors much faster, and avoid some unnecessary work when only building a subset of packages. This is especially useful for the curator use case. * Existing global option `--color=WHEN` is now also available as a non-project-specific yaml configuration parameter `color:`. * Adopt the standard proposed at http://no-color.org/, that color should not be added by default if the `NO_COLOR` environment variable is present. * New command `stack ls stack-colors` lists the styles and the associated 'ANSI' control character sequences that Stack uses to color some of its output. See `stack ls stack-colors --help` for more information. * New global option `--stack-colors=STYLES`, also available as a non-project-specific yaml configuration parameter, allows a Stack user to redefine the default styles that Stack uses to color some of its output. See `stack --help` for more information. * British English spelling of 'color' (colour) accepted as an alias for `--color`, `--stack-colors`, `stack ls stack-colors` at the command line and for `color:` and `stack-colors:` in yaml configuration files. * New build option `--ddump-dir`. (See [#4225](https://github.com/commercialhaskell/stack/issues/4225)) * Stack parses and respects the `preferred-versions` information from Hackage for choosing latest version of a package in some cases, e.g. `stack unpack packagename`. * The components output in the `The main module to load is ambiguous` message now include package names so they can be more easily copy-pasted. * Git repos are shared across multiple projects. See [#3551](https://github.com/commercialhaskell/stack/issues/3551) * Use en_US.UTF-8 locale by default in pure Nix mode so programs won't crash because of Unicode in their output [#4095](https://github.com/commercialhaskell/stack/issues/4095) * Add `--tree` to `ls dependencies` to list dependencies as tree. [#4101](https://github.com/commercialhaskell/stack/issues/4101) * Add `--pedantic` to `ghci` to run with `-Wall` and `-Werror` [#4463](https://github.com/commercialhaskell/stack/issues/4463) * Add `--cabal-files` flag to `stack ide targets` command. * Add `--stdout` flag to all `stack ide` subcommands. * Use batches when unregistering packages with `ghc-pkg`. (See [#2662](https://github.com/commercialhaskell/stack/issues/2662)) * `get-stack` script now works on Windows CI machines of Appveyor, Travis and Azure Pipelines. See [#4535](https://github.com/commercialhaskell/stack/issues/4535)/ * Show snapshot being used when `stack ghci` is invoked outside of a project directory. See [#3651](https://github.com/commercialhaskell/stack/issues/3651) * The script interpreter now accepts a `--extra-dep` flag for adding packages not present in the snapshot. Currently, this only works with packages from Hackage, not Git repos or archives. * When using the script interpreter with `--optimize` or `--compile`, Stack will perform an optimization of checking whether a newer executable exists, making reruns significantly faster. There's a downside to this, however: if you have a multifile script, and change one of the dependency modules, Stack will not automatically detect and recompile. * `stack clean` will delete the entire `.stack-work/dist` directory, not just the relevant subdirectory for the current GHC version. See [#4480](https://github.com/commercialhaskell/stack/issues/4480). * Add `stack purge` as a shortcut for `stack clean --full`. See [#3863](https://github.com/commercialhaskell/stack/issues/3863). * Both `stack dot` and `stack ls dependencies` accept a `--global-hints` flag to bypass the need for an installed GHC. See [#4390](https://github.com/commercialhaskell/stack/issues/4390). * Add the `stack config env` command for getting shell script environment variables. See [#620](https://github.com/commercialhaskell/stack/issues/620). * Less verbose output from `stack setup` on Windows. See [#1212](https://github.com/commercialhaskell/stack/issues/1212). * Add an optional `ignore-expiry` key to the `hackage-security` key of `~/.stack/config.yaml`. It allows disabling of timestamp expiration verification just like `cabal --ignore-expiry` does. The flag is not enabled by default so that the default functionality is not changed. * Include default values for most command line flags in the `--help` output. See [#893](https://github.com/commercialhaskell/stack/issues/893). * Set the `GHC_ENVIRONMENT` environment variable to specify dependency packages explicitly when running test. This is done to prevent ambiguous module name errors in `doctest` tests. * `get-stack` script now works on Windows CI machines of Appveyor, Travis and Azure Pipelines. See [#4535](https://github.com/commercialhaskell/stack/issues/4535) * Warn when a Docker image does not include a `PATH` environment variable. See [#2472](https://github.com/commercialhaskell/stack/issues/2742) * When using `system-ghc: true`, Stack will now find the appropriate GHC installation based on the version suffix, allowing you to more easily switch between various system-installed GHCs. See [#2433](https://github.com/commercialhaskell/stack/issues/2433). * `stack init` will now support create a `stack.yaml` file without any local packages. See [#2465](https://github.com/commercialhaskell/stack/issues/2465) * Store caches in SQLite database instead of files. * No longer use "global" Docker image database (`docker.db`). * User config files are respected for the script command. See [#3705](https://github.com/commercialhaskell/stack/issues/3705), [#3887](https://github.com/commercialhaskell/stack/issues/3887). * Set the `GHC_ENVIRONMENT` environment variable to `-` to tell GHC to ignore any such files when GHC is new enough (>= 8.4.4), otherwise simply unset the variable. This allows Stack to have control of package databases when running commands like `stack exec ghci`, even in the presence of implicit environment files created by `cabal new-build`. See [#4706](https://github.com/commercialhaskell/stack/issues/4706). * Use a database cache table to speed up discovery of installed GHCs * You can specify multiple `--test-arguments` options. See [#2226](https://github.com/commercialhaskell/stack/issues/2226) * Windows terminal width detection is now done. See [#3588](https://github.com/commercialhaskell/stack/issues/3588) * On Windows, informs users if the 'programs' path contains a space character and further warns users if that path does not have an alternative short ('8 dot 3') name, referencing the `local-programs-path` configuration option. See [#4726](https://github.com/commercialhaskell/stack/issues/4726) * Add `--docker-mount-mode` option to set the Docker volume mount mode for performance tuning on macOS. Bug fixes: * Ignore duplicate files for a single module when a Haskell module was generated from a preprocessor file. See [#4076](https://github.com/commercialhaskell/stack/issues/4076). * Only track down components in current directory if there are no hs-source-dirs found. This eliminates a number of false-positive warnings, similar to [#4076](https://github.com/commercialhaskell/stack/issues/4076). * Handle a change in GHC's hi-dump format around `addDependentFile`, which now includes a hash. See [yesodweb/yesod#1551](https://github.com/yesodweb/yesod/issues/1551) * Fix `subdirs` for git repos in `extra-deps` to match whole directory names. Also fixes for `subdirs: .`. See [#4292](https://github.com/commercialhaskell/stack/issues/4292) * Fix for git packages to update submodules to the correct state. See [#4314](https://github.com/commercialhaskell/stack/pull/4314) * Add `--cabal-files` flag to `stack ide targets` command. * Don't download ghc when using `stack clean`. * Support loading in GHCi definitions from symlinked C files. Without this patch, Stack will try to find object files in the directory pointed to by symlinks, while GCC will produce the object files in the original directory. See [#4402](https://github.com/commercialhaskell/stack/pull/4402) * Fix handling of GitHub and URL templates on Windows. See [#4394](https://github.com/commercialhaskell/stack/issues/4394) * Fix `--file-watch` not responding to file modifications when running inside docker on Mac. See [#4506](https://github.com/commercialhaskell/stack/issues/4506) * Using `--ghc-options` with `stack script --compile` now works. * Ensure the detailed-0.9 type tests work. See [#4453](https://github.com/commercialhaskell/stack/issues/4453). * Extra include and lib dirs are now order-dependent. See [#4527](https://github.com/commercialhaskell/stack/issues/4527). * Apply GHC options when building a `Setup.hs` file. See [#4526](https://github.com/commercialhaskell/stack/issues/4526). * Stack handles ABI changes in FreeBSD 12 by differentiating that version from previous. * Help text for the `templates` subcommand now reflects behaviour in Stack 1.9 — that it downloads and shows a help file, rather than listing available templates. * Fix detection of AArch64 platform (this broke when we upgraded to a newer Cabal version). * Docker: fix detecting and pulling missing images with `--docker-auto-pull`. See [#4598](https://github.com/commercialhaskell/stack/issues/4598) * Hackage credentials are not world-readable. See [#2159](https://github.com/commercialhaskell/stack/issues/2159). * Warnings are dumped from logs even when color is enabled. See [#2997](https://github.com/commercialhaskell/stack/issues/2997) * `stack init` will now work for Cabal files with sublibraries. See [#4408](https://github.com/commercialhaskell/stack/issues/4408) * When the Cabal spec version is newer than the global Cabal version, build against the snapshot's Cabal library. See [#4488](https://github.com/commercialhaskell/stack/issues/4488) * Docker: fix detection of expected subprocess failures. This fixes downloading a compatible `stack` executable when the host `stack` is not compatible with the Docker image (on Linux), and doesn't show an unnecessary extra error when the in-container re-exec'ed `stack` exits with failure. * The `stack ghci` command's `--ghc-options` flag now parses multiple options. See [#3315](https://github.com/commercialhaskell/stack/issues/3315). ## v1.9.3.1 - 2019-04-18 Hackage-only release with no user facing changes (added compatibility with `rio-0.1.9.2`). ## v1.9.3 - 2018-12-02 Bug fixes: * Stack can now be compiled again inside a directory that does not contain a `.git` directory. See [#4364](https://github.com/commercialhaskell/stack/issues/4364#issuecomment-431600841) * Handle a change in GHC's hi-dump format around `addDependentFile`, which now includes a hash. See [yesodweb/yesod#1551](https://github.com/yesodweb/yesod/issues/1551) * Allow variables to appear in template file names. ## v1.9.1.1 - 2018-11-14 Hackage-only release with no user facing changes. * Stack can now be compiled again inside a directory that does not contain a `.git` directory. See [#4364](https://github.com/commercialhaskell/stack/issues/4364#issuecomment-431600841) ## v1.9.1 - 2018-10-17 Release notes: * Statically-linked Linux executables are back again, thanks to [@nh2](https://github.com/nh2). * We will be deleting the Ubuntu, Debian, CentOS, Fedora, and Arch package repos from `download.fpcomplete.com` soon. These have been deprecated for over a year and have not received new releases, but were left in place for compatibility with older scripts. Major changes: * Upgrade to Cabal 2.4 * Note that, in this process, the behavior of file globbing has been modified to match that of Cabal. In particular, this means that for Cabal spec versions less than 2.4, `*.txt` will match `foo.txt`, but not `foo.2.txt`. * `GHCJS` support is being downgraded to 'experimental'. A warning notifying the user of the experimental status of `GHCJS` will be displayed. Behavior changes: * `ghc-options` from `stack.yaml` are now appended to `ghc-options` from `config.yaml`, whereas before they would be replaced. * `stack build` will now announce when sublibraries of a package are being build, in the same way executables, tests, benchmarks and libraries are announced * `stack sdist` will now announce the destination of the generated tarball, regardless of whether or not it passed the sanity checks * The `--upgrade-cabal` option to `stack setup` has been deprecated. This feature no longer works with GHC 8.2 and later. Furthermore, the reason for this flag originally being implemented was drastically lessened once Stack started using the snapshot's `Cabal` library for custom setups. See: [#4070](https://github.com/commercialhaskell/stack/issues/4070). * With the new namespaced template feature, `stack templates` is no longer able to meaningfully display a list of all templates available. Instead, the command will download and display a [help file](https://github.com/commercialhaskell/stack-templates/blob/master/STACK_HELP.md) with more information on how to discover templates. See: [#4039](https://github.com/commercialhaskell/stack/issues/4039) * Tools used during building ('build tools') are now handled in a similar way to `cabal-install`. In particular, for legacy `build-tools` fields, we use a hard-coded list of build tools in place of looking up build tool packages in a tool map. This both brings Stack's behavior closer into line with `cabal-install`, avoids some bugs, and opens up some possible optimizations/laziness. See: [#4125](https://github.com/commercialhaskell/stack/issues/4125). * Mustache templating is not applied to large files (over 50kb) to avoid performance degradation. See: [#4133](https://github.com/commercialhaskell/stack/issues/4133). * `stack upload` signs the package by default, as documented. `--no-signature` turns the signing off. [#3739](https://github.com/commercialhaskell/stack/issues/3739) * In case there is a network connectivity issue while trying to download a template, Stack will check whether that template had been downloaded before. In that case, the cached version will be used. See [#3850](https://github.com/commercialhaskell/stack/issues/3850). * In Stack's script interpreter, `-- stack --verbosity=info script` and `-- stack script --verbosity=info` now have the same effect and both override the `--verbosity=error` default in the interpreter. Previously the default meant the former was equivalent to `-- stack --verbosity=info script --verbosity=error` and the latter was equivalent to `-- stack --verbosity=error script --verbosity=info`, with the subcommand's global option having precedence over the Stack command's global option in each case. See [#5326](https://github.com/commercialhaskell/stack/issues/5326). Other enhancements: * On Windows before Windows 10, --color=never is the default on terminals that can support ANSI color codes in output only by emulation * On Windows, recognise a 'mintty' (false) terminal as a terminal, by default * `stack build` issues a warning when `base` is explicitly listed in `extra-deps` of `stack.yaml` * `stack build` suggests trying another GHC version should the build plan end up requiring unattainable `base` version. * A new sub command `run` has been introduced to build and run a specified executable similar to `cabal run`. If no executable is provided as the first argument, it defaults to the first available executable in the project. * `stack build` missing dependency suggestions (on failure to construct a valid build plan because of missing deps) are now printed with their latest Cabal file revision hash. See [#4068](https://github.com/commercialhaskell/stack/pull/4068). * Added new `--tar-dir` option to `stack sdist`, that allows to copy the resulting tarball to the specified directory. * Introduced the `--interleaved-output` command line option and `build.interleaved-output` config value which causes multiple concurrent builds to dump to stderr at the same time with a `packagename> ` prefix. See [#3225](https://github.com/commercialhaskell/stack/issues/3225). * The default retry strategy has changed to exponential backoff. This should help with [#3510](https://github.com/commercialhaskell/stack/issues/3510). * `stack new` now allows template names of the form `username/foo` to download from a user other than `commercialstack` on GitHub, and can be prefixed with the service `github:`, `gitlab:`, or `bitbucket:`. See [#4039](https://github.com/commercialhaskell/stack/issues/4039) * Switch to `githash` to include some unmerged bugfixes in `gitrev` Suggestion to add `'allow-newer': true` now shows path to user config file where this flag should be put into [#3685](https://github.com/commercialhaskell/stack/issues/3685) * `stack ghci` now asks which main target to load before doing the build, rather than after * Bump to Hpack 0.29.0 * With GHC 8.4 and later, Haddock is given the `--quickjump` flag. * It is possible to specify the Hackage base URL to upload packages to, instead of the default of `https://hackage.haskell.org/`, by using `hackage-base-url` configuration option. * When using Nix, if a specific minor version of GHC is not requested, the latest minor version in the given major branch will be used automatically. Bug fixes: * `stack ghci` now does not invalidate `.o` files on repeated runs, meaning any modules compiled with `-fobject-code` will be cached between ghci runs. See [#4038](https://github.com/commercialhaskell/stack/pull/4038). * `~/.stack/config.yaml` and `stack.yaml` terminating by newline * The previous released caused a regression where some `stderr` from the `ghc-pkg` command showed up in the terminal. This output is now silenced. * A regression in recompilation checking introduced in v1.7.1 has been fixed. See [#4001](https://github.com/commercialhaskell/stack/issues/4001) * `stack ghci` on a package with internal libraries was erroneously looking for a wrong package corresponding to the internal library and failing to load any module. This has been fixed now and changes to the code in the library and the sublibrary are properly tracked. See [#3926](https://github.com/commercialhaskell/stack/issues/3926). * For packages with internal libraries not depended upon, `stack build` used to fail the build process since the internal library was not built but it was tried to be registered. This is now fixed by always building internal libraries. See [#3996](https://github.com/commercialhaskell/stack/issues/3996). * `--no-nix` was not respected under NixOS * Fix a regression which might use a lot of RAM. See [#4027](https://github.com/commercialhaskell/stack/issues/4027). * Order of commandline arguments does not matter anymore. See [#3959](https://github.com/commercialhaskell/stack/issues/3959) * When prompting users about saving their Hackage credentials on upload, flush to stdout before waiting for the response so the prompt actually displays. Also fixes a similar issue with ghci target selection prompt. * If `cabal` is not on PATH, running `stack solver` now prompts the user to run `stack install cabal-install` * `stack build` now succeeds in building packages which contain sublibraries which are dependencies of executables, tests or benchmarks but not of the main library. See [#3787](https://github.com/commercialhaskell/stack/issues/3787). * Sublibraries are now properly considered for coverage reports when the test suite depends on the internal library. Before, Stack was erroring when trying to generate the coverage report, see [#4105](https://github.com/commercialhaskell/stack/issues/4105). * Sublibraries are now added to the precompiled cache and recovered from there when the snapshot gets updated. Previously, updating the snapshot when there was a package with a sublibrary in the snapshot resulted in broken builds. This is now fixed, see [#4071](https://github.com/commercialhaskell/stack/issues/4071). * [#4114](https://github.com/commercialhaskell/stack/issues/4114) Stack pretty prints error messages with proper `error` logging level instead of `warning` now. This also fixes self-executing scripts not piping plan construction errors from runhaskell to terminal (issue [#3942](https://github.com/commercialhaskell/stack/issues/3942)). * Fix invalid "While building Setup.hs" when Cabal calls fail. See: [#3934](https://github.com/commercialhaskell/stack/issues/3934) * `stack upload` signs the package by default, as documented. `--no-signature` turns the signing off. [#3739](https://github.com/commercialhaskell/stack/issues/3739) ## v1.7.1 - 2018-04-27 Release notes: * AArch64 (64-bit ARM) executables are now available for the first time. * Statically-linked Linux executables are no longer available, due to difficulty with GHC 8.2.2 on Alpine Linux. * 32-bit Linux GMP4 executables for CentOS 6 are no longer available, since GHC 8.2.2 is no longer being built for that platform. Major changes: * Upgrade from Cabal 2.0 to Cabal 2.2 Behavior changes: * `stack setup` no longer uses different GHC configure options on Linux distributions that use GCC with PIE enabled by default. GHC detects this itself since ghc-8.0.2, and Stack's attempted workaround for older versions caused more problems than it solved. * `stack new` no longer initializes a project if the project template contains a `stack.yaml` file. Other enhancements: * A new sub command `ls` has been introduced to Stack to view local and remote snapshots present in the system. Use `stack ls snapshots --help` to get more details about it. * `list-dependencies` has been deprecated. The functionality has to accessed through the new `ls dependencies` interface. See [#3669](https://github.com/commercialhaskell/stack/issues/3669) for details. * Specify User-Agent HTTP request header on every HTTP request. See [#3628](https://github.com/commercialhaskell/stack/issues/3628) for details. * `stack setup` looks for GHC binary distributions and installations by any OS key that is compatible (rather than only checking a single one). This is relevant on Linux where different distributions may have different combinations of libtinfo 5/6, ncurses 5/6, and gmp 4/5, and will allow simplifying the setup-info metadata YAML for future GHC releases. * The build progress bar reports names of packages currently building. * `stack setup --verbose` causes verbose output of GHC configure process. See [#3716](https://github.com/commercialhaskell/stack/issues/3716) * Improve the error message when an `extra-dep` from a path or git reference can't be found. See [#3808](https://github.com/commercialhaskell/stack/pull/3808) * Nix integration is now disabled on windows even if explicitly enabled, since it isn't supported. See [#3600](https://github.com/commercialhaskell/stack/issues/3600) * `stack build` now supports a new flag `--keep-tmp-files` to retain intermediate files and directories for the purpose of debugging. It is best used with ghc's equivalent flag, i.e. `stack build --keep-tmp-files --ghc-options=-keep-tmp-files`. See [#3857](https://github.com/commercialhaskell/stack/issues/3857) * Improved error messages for snapshot parse exceptions * `stack unpack` now supports a `--to /target/directory` option to specify where to unpack the package into * `stack hoogle` now supports a new flag `--server` that launches local Hoogle server on port 8080. See [#2310](https://github.com/commercialhaskell/stack/issues/2310) Bug fixes: * The script interpreter's implicit file arguments are now passed before other arguments. See [#3658](https://github.com/commercialhaskell/stack/issues/3658). In particular, this makes it possible to pass `-- +RTS ... -RTS` to specify RTS arguments used when running the script. * Don't ignore the template `year` parameter in config files, and clarify the surrounding documentation. See [#2275](https://github.com/commercialhaskell/stack/issues/2275). * Benchmarks used to be run concurrently with other benchmarks and build steps. This is non-ideal because CPU usage of other processes may interfere with benchmarks. It also prevented benchmark output from being displayed by default. This is now fixed. See [#3663](https://github.com/commercialhaskell/stack/issues/3663). * `stack ghci` now allows loading multiple packages with the same module name, as long as they have the same filepath. See [#3776](https://github.com/commercialhaskell/stack/pull/3776). * `stack ghci` no longer always adds a dependency on `base`. It is now only added when there are no local targets. This allows it to be to load code that uses replacements for `base`. See [#3589](https://github.com/commercialhaskell/stack/issues/3589#issuecomment) * `stack ghci` now uses correct paths for autogen files with [#3791](https://github.com/commercialhaskell/stack/issues/3791) * When a package contained sublibraries, Stack was always recompiling the package. This has been fixed now, no recompilation is being done because of sublibraries. See [#3899](https://github.com/commercialhaskell/stack/issues/3899). * The `get-stack.sh` install script now matches manual instructions when it comes to Debian/Fedora/CentOS install dependencies. * Compile Cabal-simple with gmp when using Nix. See [#2944](https://github.com/commercialhaskell/stack/issues/2944) * `stack ghci` now replaces the Stack process with ghci. This improves signal handling behavior. In particular, handling of Ctrl-C. To make this possible, the generated files are now left behind after exit. The paths are based on hashing file contents, and it's stored in the system temporary directory, so this shouldn't result in too much garbage. See [#3821](https://github.com/commercialhaskell/stack/issues/3821). ## v1.6.5 - 2018-02-19 Bug fixes: * Some unnecessary rebuilds when no files were changed are now avoided, by having a separate build cache for each component of a package. See [#3732](https://github.com/commercialhaskell/stack/issues/3732). * Correct the behavior of promoting a package from snapshot to local package. This would get triggered when version bounds conflicted in a snapshot, which could be triggered via Hackage revisions for old packages. This also should allow custom snapshots to define conflicting versions of packages without issue. See [Stackage issue #3185](https://github.com/fpco/stackage/issues/3185). * When promoting packages from snapshot to local, we were occasionally discarding the actual package location content and instead defaulting to pulling the package from the index. We now correctly retain this information. Note that if you were affected by this bug, you will likely need to delete the binary build cache associated with the relevant custom snapshot. See [#3714](https://github.com/commercialhaskell/stack/issues/3714). * `--no-rerun-tests` has been fixed. Previously, after running a test we were forgetting to record the result, which meant that all tests always ran even if they had already passed before. See [#3770](https://github.com/commercialhaskell/stack/pull/3770). * Includes a patched version of `hackage-security` which fixes both some issues around asynchronous exception handling, and moves from directory locking to file locking, making the update mechanism resilient against SIGKILL and machine failure. See `hackage-security` issue [#187](https://github.com/haskell/hackage-security/issues/187) and Stack issue [#3073](https://github.com/commercialhaskell/stack/issues/3073). ## v1.6.3.1 - 2018-02-16 Hackage-only release with no user facing changes (updated to build with newer version of Hpack dependency). ## v1.6.3 - 2017-12-23 Enhancements: * In addition to supporting `.tar.gz` and `.zip` files as remote archives, plain `.tar` files are now accepted too. This will additionally help with cases where HTTP servers mistakenly set the transfer encoding to `gzip`. See [#3647](https://github.com/commercialhaskell/stack/issues/3647). * Links to docs.haskellstack.org ignore Stack version patchlevel. * Downloading Docker-compatible `stack` executable ignores Stack version patchlevel. Bug fixes: * For versions of Cabal before 1.24, ensure that the dependencies of non-buildable components are part of the build plan to work around an old Cabal bug. See [#3631](https://github.com/commercialhaskell/stack/issues/3631). * Run the Cabal file checking in the `sdist` command more reliably by allowing the Cabal library to flatten the `GenericPackageDescription` itself. ## v1.6.1.1 - 2017-12-20 Hackage-only release with no user facing changes (updated to build with newer dependency versions). ## v1.6.1 - 2017-12-07 Major changes: * Complete overhaul of how snapshots are defined, the `packages` and `extra-deps` keys, and a number of related items. For full details, please see the [writeup](https://www.fpcomplete.com/blog/2017/07/stacks-new-extensible-snapshots) on these changes. [PR #3249](https://github.com/commercialhaskell/stack/pull/3249), see the PR description for a number of related issues. * Upgraded to version 2.0 of the Cabal library. Behavior changes: * The `--install-ghc` flag is now on by default. For example, if you run `stack build` in a directory requiring a GHC that you do not currently have, Stack will automatically download and install that GHC. You can explicitly set `install-ghc: false` or pass the flag `--no-install-ghc` to regain the previous behavior. * `stack ghci` no longer loads modules grouped by package. This is always an improvement for plain ghci - it makes loading faster and less noisy. For intero, this has the side-effect that it will no longer load multiple packages that depend on TH loading relative paths. TH relative paths will still work when loading a single package into intero. See [#3309](https://github.com/commercialhaskell/stack/issues/3309) * Setting GHC options for a package via `ghc-options:` in your `stack.yaml` will promote it to a local package, providing for more consistency with flags and better reproducibility. See: [#849](https://github.com/commercialhaskell/stack/issues/849) * The `package-indices` setting with Hackage no longer works with the `00-index.tar.gz` tarball, but must use the `01-index.tar.gz` file to allow revised packages to be found. * Options passed via `--ghci-options` are now passed to the end of the invocation of ghci, instead of the middle. This allows using `+RTS` without an accompanying `-RTS`. * When auto-detecting `--ghc-build`, `tinfo6` is now preferred over `standard` if both versions of libtinfo are installed * Addition of `stack build --copy-compiler-tool`, to allow tools like intero to be installed globally for a particular compiler. [#2643](https://github.com/commercialhaskell/stack/issues/2643) * Stack will ask before saving hackage credentials to file. This new prompt can be avoided by using the `save-hackage-creds` setting. Please see [#2159](https://github.com/commercialhaskell/stack/issues/2159). * The `GHCRTS` environment variable will no longer be passed through to every program Stack runs. Instead, it will only be passed through commands like `exec`, `runghc`, `script`, `ghci`, etc. See [#3444](https://github.com/commercialhaskell/stack/issues/3444). * `ghc-options:` for specific packages will now come after the options specified for all packages / particular sets of packages. See [#3573](https://github.com/commercialhaskell/stack/issues/3573). * The `pvp-bounds` feature is no longer fully functional, due to some issues with the Cabal library's printer. See [#3550](https://github.com/commercialhaskell/stack/issues/3550). Other enhancements: * The `with-hpack` configuration option specifies an Hpack executable to use instead of the Hpack bundled with Stack. Please see [#3179](https://github.com/commercialhaskell/stack/issues/3179). * It's now possible to skip tests and benchmarks using `--skip` flag * `GitSHA1` is now `StaticSHA256` and is implemented using the `StaticSize 64 ByteString` for improved performance. See [#3006](https://github.com/commercialhaskell/stack/issues/3006) * Dependencies via HTTP(S) archives have been generalized to allow local file path archives, as well as to support setting a cryptographic hash (SHA256) of the contents for better reproducibility. * Allow specifying `--git-branch` when upgrading * When running `stack upgrade` from a file which is different from the default executable path (e.g., on POSIX systems, `~/.local/bin/stack`), it will now additionally copy the new executable over the currently running `stack` executable. If permission is denied (such as in `/usr/local/bin/stack`), the user will be prompted to try again using `sudo`. This is intended to assist with the user experience when the `PATH` environment variable has not been properly configured, see [#3232](https://github.com/commercialhaskell/stack/issues/3232). * `stack setup` for ghcjs will now install `alex` and `happy` if they are not present. See [#3109](https://github.com/commercialhaskell/stack/issues/3232). * Added `stack ghci --only-main` flag, to skip loading / importing all but main modules. See the ghci documentation page for further info. * Allow GHC's colored output to show through. GHC colors output starting with version 8.2.1, for older GHC this does nothing. Sometimes GHC's heuristics would work fine even before this change, for example in `stack ghci`, but this override's GHC's heuristics when they're broken by our collecting and processing GHC's output. * Extended the `ghc-options` key to support `$locals`, `$targets`, and `$everything`. See: [#3329](https://github.com/commercialhaskell/stack/issues/3329) * Better error message for case that `stack ghci` file targets are combined with invalid package targets. See: [#3342](https://github.com/commercialhaskell/stack/issues/3342) * For profiling now uses `-fprof-auto -fprof-cafs` instead of the deprecated `-auto-all -caf-all`. See: [#3360](https://github.com/commercialhaskell/stack/issues/3360) * Better descriptions are now available for `stack upgrade --help`. See: [#3070](https://github.com/commercialhaskell/stack/issues/3070) * When using Nix, nix-shell now depends always on gcc to prevent build errors when using the FFI. As ghc depends on gcc anyway, this doesn't increase the dependency footprint. * `--cwd DIR` can now be passed to `stack exec` in order to execute the program in a different directory. See: [#3264](https://github.com/commercialhaskell/stack/issues/3264) * Plan construction will detect if you add an executable-only package as a library dependency, resulting in much clearer error messages. See: [#2195](https://github.com/commercialhaskell/stack/issues/2195). * Addition of `--ghc-options` to `stack script` to pass options directly to GHC. See: [#3454](https://github.com/commercialhaskell/stack/issues/3454) * Add Hpack `package.yaml` to build Stack itself * Add `ignore-revision-mismatch` setting. See: [#3520](https://github.com/commercialhaskell/stack/issues/3520). * Log when each individual test suite finishes. See: [#3552](https://github.com/commercialhaskell/stack/issues/3552). * Avoid spurious rebuilds when using `--file-watch` by not watching files for executable, test and benchmark components that aren't a target. See: [#3483](https://github.com/commercialhaskell/stack/issues/3483). * Stack will now try to detect the width of the running terminal (only on POSIX for the moment) and use that to better display output messages. Work is ongoing, so some messages will not be optimal yet. The terminal width can be overridden with the new `--terminal-width` command-line option (this works even on non-POSIX). * Passing non local packages as targets to `stack ghci` will now cause them to be used as `-package` args along with package hiding. * Detect when user changed Cabal file instead of `package.yaml`. This was implemented upstream in Hpack. See [#3383](https://github.com/commercialhaskell/stack/issues/3383). * Automatically run `autoreconf -i` as necessary when a `configure` script is missing. See [#3534](https://github.com/commercialhaskell/stack/issues/3534) * GHC binary distributions can now be identified by their SHA256 checksum in addition to their SHA1 checksum, allowing for more security in download. * For filesystem setup-info paths, it's no longer assumed that the directory is writable, instead a temp dir is used. See [#3188](https://github.com/commercialhaskell/stack/issues/3188). Bug fixes: * `stack hoogle` correctly generates Hoogle databases. See: [#3362](https://github.com/commercialhaskell/stack/issues/3362) * `stack --docker-help` is now clearer about --docker implying system-ghc: true, rather than both --docker and --no-docker. * `stack haddock` now includes package names for all modules in the Haddock index page. See: [#2886](https://github.com/commercialhaskell/stack/issues/2886) * Fixed an issue where Stack wouldn't detect missing Docker images properly with newer Docker versions. [#3171](https://github.com/commercialhaskell/stack/pull/3171) * Previously, Cabal files with just test-suite could cause build to fail ([#2862](https://github.com/commercialhaskell/stack/issues/2862)) * If an invalid snapshot file has been detected (usually due to mismatched hashes), Stack will delete the downloaded file and recommend either retrying or filing an issue upstream. See [#3319](https://github.com/commercialhaskell/stack/issues/3319). * Modified the flag parser within Stack to match the behavior of Cabal's flag parser, which allows multiple sequential dashes. See [#3345](https://github.com/commercialhaskell/stack/issues/3345) * Now clears the hackage index cache if it is older than the downloaded index. Fixes potential issue if Stack was interrupted when updating index. See [#3033](https://github.com/commercialhaskell/stack/issues/3033) * The Stack install script now respects the `-d` option. See [#3366](https://github.com/commercialhaskell/stack/pull/3366). * `stack script` can now handle relative paths to source files. See [#3372](https://github.com/commercialhaskell/stack/issues/3372). * Fixes explanation of why a target is needed by the build plan, when the target is an extra-dep from the commandline. See [#3378](https://github.com/commercialhaskell/stack/issues/3378). * Previously, if you delete a yaml file from ~/.stack/build-plan, it would trust the etag and not re-download. Fixed in this version. * Invoking `stack --docker` in parallel now correctly locks the sqlite database. See [#3400](https://github.com/commercialhaskell/stack/issues/3400). * docs.haskellstack.org RTD documentation search is replaced by the mkdocs search. Please see [#3376](https://github.com/commercialhaskell/stack/issues/3376). * `stack clean` now works with nix. See [#3468](https://github.com/commercialhaskell/stack/issues/3376). * `stack build --only-dependencies` no longer builds local project packages that are depended on. See [#3476](https://github.com/commercialhaskell/stack/issues/3476). * Properly handle relative paths stored in the precompiled cache files. See [#3431](https://github.com/commercialhaskell/stack/issues/3431). * In some cases, Cabal does not realize that it needs to reconfigure, and must be told to do so automatically. This would manifest as a "shadowed dependency" error message. We now force a reconfigure whenever a dependency is built, even if the package ID remained the same. See [#2781](https://github.com/commercialhaskell/stack/issues/2781). * When `--pvp-bounds` is enabled for sdist or upload, internal dependencies could cause errors when uploaded to hackage. This is fixed, see [#3290](https://github.com/commercialhaskell/stack/issues/3290) * Fixes a bug where nonexistent hackage versions would cause Stack to suggest the same package name, without giving version info. See [#3562](https://github.com/commercialhaskell/stack/issues/3562) * Fixes a bug that has existed since 1.5.0, where `stack setup --upgrade-cabal` would say that Cabal is already the latest version, when it wasn't. * Ensure that an `extra-dep` from a local directory is not treated as a `$locals` for GHC options purposes. See [#3574](https://github.com/commercialhaskell/stack/issues/3574). * Building all executables only happens once instead of every time. See [#3229](https://github.com/commercialhaskell/stack/issues/3229) for more info. ## 1.5.1 - 2017-08-05 Bug fixes: * Stack eagerly tries to parse all Cabal files related to a snapshot. Starting with Stackage Nightly 2017-07-31, snapshots are using GHC 8.2.1, and the `ghc.cabal` file implicitly referenced uses the (not yet supported) Cabal 2.0 file format. Future releases of Stack will both be less eager about Cabal file parsing and support Cabal 2.0. This patch simply bypasses the error for invalid parsing. ## 1.5.0 - 2017-07-25 Behavior changes: * `stack profile` and `stack trace` now add their extra RTS arguments for benchmarks and tests to the beginning of the args, instead of the end. See [#2399](https://github.com/commercialhaskell/stack/issues/2399) * Support for Git-based indices has been removed. Other enhancements: * `stack setup` allow to control options passed to ghcjs-boot with `--ghcjs-boot-options` (one word at a time) and `--[no-]ghcjs-boot-clean` * `stack setup` now accepts a `--install-cabal VERSION` option which will install a specific version of the Cabal library globally. * Updates to store-0.4.1, which has improved performance and better error reporting for version tags. A side-effect of this is that all of stack's binary caches will be invalidated. * `stack solver` will now warn about unexpected `cabal-install` versions. See [#3044](https://github.com/commercialhaskell/stack/issues/3044) * Upstream packages unpacked to a temp dir are now deleted as soon as possible to avoid running out of space in `/tmp`. See [#3018](https://github.com/commercialhaskell/stack/issues/3018) * Add short synonyms for `test-arguments` and `benchmark-arguments` options. * Adds `STACK_WORK` environment variable, to specify work dir. See [#3063](https://github.com/commercialhaskell/stack/issues/3063) * Can now use relative paths for `extra-include-dirs` and `extra-lib-dirs`. See [#2830](https://github.com/commercialhaskell/stack/issues/2830) * Improved bash completion for many options, including `--ghc-options`, `--flag`, targets, and project executables for `exec`. * `--haddock-arguments` is actually used now when `haddock` is invoked during documentation generation. * `--[no-]haddock-hyperlink-source` flag added which allows toggling of sources being included in Haddock output. See [#3099](https://github.com/commercialhaskell/stack/issues/3099) * `stack ghci` will now skip building all local targets, even if they have downstream deps, as long as it's registered in the DB. * The `pvp-bounds` feature now supports adding `-revision` to the end of each value, e.g. `pvp-bounds: both-revision`. This means that, when uploading to Hackage, Stack will first upload your tarball with an unmodified Cabal file, and then upload a Cabal file revision with the PVP bounds added. This can be useful - especially combined with the [Stackage no-revisions feature](http://www.snoyman.com/blog/2017/04/stackages-no-revisions-field) - as a method to ensure PVP compliance without having to proactively fix bounds issues for Stackage maintenance. * Expose a `save-hackage-creds` configuration option * On GHC <= 7.8, filters out spurious linker warnings on windows See [#3127](https://github.com/commercialhaskell/stack/pull/3127) * Better error messages when creating or building packages which alias wired-in packages. See [#3172](https://github.com/commercialhaskell/stack/issues/3172). * MinGW bin folder now is searched for dynamic libraries. See [#3126](https://github.com/commercialhaskell/stack/issues/3126) * When using Nix, nix-shell now depends always on git to prevent runtime errors while fetching metadata * Experimental: The `stack unpack` command now accepts a form where an explicit Hackage revision hash is specified, e.g. `stack unpack foo-1.2.3@gitsha1:deadbeef`. Note that Stack will likely move towards a different hash format in the future. * Binary "stack upgrade" will now warn if the installed executable is not on the PATH or shadowed by another entry. * Allow running tests on tarball created by sdist and upload [#717](https://github.com/commercialhaskell/stack/issues/717). Bug fixes: * Fixes case where `stack build --profile` might not cause executables / tests / benchmarks to be rebuilt. See [#2984](https://github.com/commercialhaskell/stack/issues/2984) * `stack ghci file.hs` now loads the file even if it isn't part of your project. * `stack clean --full` now works when docker is enabled. See [#2010](https://github.com/commercialhaskell/stack/issues/2010) * Fixes an issue where cyclic deps can cause benchmarks or tests to be run before they are built. See [#2153](https://github.com/commercialhaskell/stack/issues/2153) * Fixes `stack build --file-watch` in cases where a directory is removed See [#1838](https://github.com/commercialhaskell/stack/issues/1838) * Fixes `stack dot` and `stack list-dependencies` to use info from the package database for wired-in-packages (ghc, base, etc). See [#3084](https://github.com/commercialhaskell/stack/issues/3084) * Fixes `stack --docker build` when user is part of libvirt/libvirtd groups on Ubuntu Yakkety (16.10). See [#3092](https://github.com/commercialhaskell/stack/issues/3092) * Switching a package between extra-dep and local package now forces rebuild (previously it wouldn't if versions were the same). See [#2147](https://github.com/commercialhaskell/stack/issues/2147) * `stack upload` no longer reveals your password when you type it on MinTTY-based Windows shells, such as Cygwin and MSYS2. See [#3142](https://github.com/commercialhaskell/stack/issues/3142) * `stack script`'s import parser will now properly parse files that have Windows-style line endings (CRLF) ## 1.4.0 - 2017-03-15 Release notes: * Docker images: [fpco/stack-full](https://hub.docker.com/r/fpco/stack-full/) and [fpco/stack-run](https://hub.docker.com/r/fpco/stack-run/) are no longer being built for LTS 8.0 and above. [fpco/stack-build](https://hub.docker.com/r/fpco/stack-build/) images continue to be built with a [simplified process](https://github.com/commercialhaskell/stack/tree/master/etc/dockerfiles/stack-build). [#624](https://github.com/commercialhaskell/stack/issues/624) Major changes: * A new command, `script`, has been added, intended to make the script interpreter workflow more reliable, easier to use, and more efficient. This command forces the user to provide a `--resolver` value, ignores all config files for more reproducible results, and optimizes the existing package check to make the common case of all packages already being present much faster. This mode does require that all packages be present in a snapshot, however. [#2805](https://github.com/commercialhaskell/stack/issues/2805) Behavior changes: * The default package metadata backend has been changed from Git to the 01-index.tar.gz file, from the hackage-security project. This is intended to address some download speed issues from GitHub for people in certain geographic regions. There is now full support for checking out specific Cabal file revisions from downloaded tarballs as well. If you manually specify a package index with only a Git URL, Git will still be used. See [#2780](https://github.com/commercialhaskell/stack/issues/2780) * When you provide the `--resolver` argument to the `stack unpack` command, any packages passed in by name only will be looked up in the given snapshot instead of taking the latest version. For example, `stack --resolver lts-7.14 unpack mtl` will get version 2.2.1 of `mtl`, regardless of the latest version available in the package indices. This will also force the same Cabal file revision to be used as is specified in the snapshot. Unpacking via a package identifier (e.g. `stack --resolver lts-7.14 unpack mtl-2.2.1`) will ignore any settings in the snapshot and take the most recent revision. For backwards compatibility with tools relying on the presence of a `00-index.tar`, Stack will copy the `01-index.tar` file to `00-index.tar`. Note, however, that these files are different; most importantly, 00-index contains only the newest revisions of Cabal files, while 01-index contains all versions. You may still need to update your tooling. * Passing `--(no-)nix-*` options now no longer implies `--nix`, except for `--nix-pure`, so that the user preference whether or not to use Nix is honored even in the presence of options that change the Nix behavior. Other enhancements: * Internal cleanup: configuration types are now based much more on lenses * `stack build` and related commands now allow the user to disable debug symbol stripping with new `--no-strip`, `--no-library-stripping`, and `--no-executable-shipping` flags, closing [#877](https://github.com/commercialhaskell/stack/issues/877). Also turned error message for missing targets more readable ([#2384](https://github.com/commercialhaskell/stack/issues/2384)) * `stack haddock` now shows index.html paths when documentation is already up to date. Resolved [#781](https://github.com/commercialhaskell/stack/issues/781) * Respects the `custom-setup` stanza introduced in Cabal 1.24. This supercedes any `explicit-setup-deps` settings in your `stack.yaml` and trusts the package's Cabal file to explicitly state all its dependencies. * If system package installation fails, `get-stack.sh` will fail as well. Also shows warning suggesting to run `apt-get update` or similar, depending on the OS. ([#2898](https://github.com/commercialhaskell/stack/issues/2898)) * When `stack ghci` is run with a config with no packages (e.g. global project), it will now look for source files in the current work dir. ([#2878](https://github.com/commercialhaskell/stack/issues/2878)) * Bump to Hpack 0.17.0 to allow `custom-setup` and `!include "..."` in `package.yaml`. * The script interpreter will now output error logging. In particular, this means it will output info about plan construction errors. ([#2879](https://github.com/commercialhaskell/stack/issues/2879)) * `stack ghci` now takes `--flag` and `--ghc-options` again (inadvertently removed in 1.3.0). ([#2986](https://github.com/commercialhaskell/stack/issues/2986)) * `stack exec` now takes `--rts-options` which passes the given arguments inside of `+RTS ... args .. -RTS` to the executable. This works around Stack itself consuming the RTS flags on Windows. ([#2640](https://github.com/commercialhaskell/stack/issues/2640)) * Upgraded `http-client-tls` version, which now offers support for the `socks5://` and `socks5h://` values in the `http_proxy` and `https_proxy` environment variables. Bug fixes: * Bump to Hpack 0.16.0 to avoid character encoding issues when reading and writing on non-UTF8 systems. * `stack ghci` will no longer ignore hsSourceDirs that contain `..`. ([#2895](https://github.com/commercialhaskell/stack/issues/2895)) * `stack list-dependencies --license` now works for wired-in-packages, like base. ([#2871](https://github.com/commercialhaskell/stack/issues/2871)) * `stack setup` now correctly indicates when it uses system ghc ([#2963](https://github.com/commercialhaskell/stack/issues/2963)) * Fix to `stack config set`, in 1.3.2 it always applied to the global project. ([#2709](https://github.com/commercialhaskell/stack/issues/2709)) * Previously, Cabal files without exe or lib would fail on the "copy" step. ([#2862](https://github.com/commercialhaskell/stack/issues/2862)) * `stack upgrade --git` now works properly. Workaround for affected versions (>= 1.3.0) is to instead run `stack upgrade --git --source-only`. ([#2977](https://github.com/commercialhaskell/stack/issues/2977)) * Added support for GHC 8's slightly different warning format for dumping warnings from logs. * Work around a bug in Cabal/GHC in which package IDs are not unique for different source code, leading to Stack not always rebuilding packages depending on local packages which have changed. ([#2904](https://github.com/commercialhaskell/stack/issues/2904)) ## 1.3.2 - 2016-12-27 Bug fixes: * `stack config set` can now be used without a compiler installed [#2852](https://github.com/commercialhaskell/stack/issues/2852). * `get-stack.sh` now installs correct executable on ARM for generic Linux and raspbian, closing [#2856](https://github.com/commercialhaskell/stack/issues/2856). * Correct the testing of whether a package database exists by checking for the `package.cache` file itself instead of the containing directory. * Revert a change in the previous release which made it impossible to set local extra-dep packages as targets. This was overkill; we really only wanted to disable their test suites, which was already handled by a later patch. [#2849](https://github.com/commercialhaskell/stack/issues/2849) * `stack new` always treats templates as being UTF-8 encoding, ignoring locale settings on a local machine. See [Yesod mailing list discussion](https://groups.google.com/d/msg/yesodweb/ZyWLsJOtY0c/aejf9E7rCAAJ) ## 1.3.0 - 2016-12-12 Release notes: * For the _next_ Stack release after this one, we are planning changes to our Linux releases, including dropping our Ubuntu, Debian, CentOS, and Fedora package repositories and switching to statically-linked executables. See [#2534](https://github.com/commercialhaskell/stack/issues/2534). Note that upgrading without a package manager has gotten easier with new binary upgrade support in `stack upgrade` (see the Major Changes section below for more information). In addition, the get.haskellstack.org script no longer installs from Ubuntu, Debian, CentOS, or Fedora package repositories. Instead it places a generic executable in /usr/local/bin. Major changes: * Stack will now always use its own GHC installation, even when a suitable GHC installation is available on the PATH. To get the old behaviour, use the `--system-ghc` flag or run `stack config set system-ghc --global true`. Docker- and Nix-enabled projects continue to use the GHC installations in their environment by default. NB: Scripts that previously used Stack in combination with a system GHC installation should now include a `stack setup` line or use the `--install-ghc` flag. [#2221](https://github.com/commercialhaskell/stack/issues/2221) * `stack ghci` now defaults to skipping the build of target packages, because support has been added for invoking "initial build steps", which create autogen files and run preprocessors. The `--no-build` flag is now deprecated because it should no longer be necessary. See [#1364](https://github.com/commercialhaskell/stack/issues/1364) * Stack is now capable of doing binary upgrades instead of always recompiling a new version from source. Running `stack upgrade` will now default to downloading a Stack executable from the most recent release, if one is available. See `stack upgrade --help` for more options. [#1238](https://github.com/commercialhaskell/stack/issues/1238) Behavior changes: * Passing `--resolver X` with a Stack command which forces creation of a global project config, will pass resolver X into the initial config. See [#2579](https://github.com/commercialhaskell/stack/issues/2229). * Switch the "Run from outside project" messages to debug-level, to avoid spamming users in the normal case of non-project usage * If a remote package is specified (such as a Git repo) without an explicit `extra-dep` setting, a warning is given to the user to provide one explicitly. Other enhancements: * `stack haddock` now supports `--haddock-internal`. See [#2229](https://github.com/commercialhaskell/stack/issues/2229) * Add support for `system-ghc` and `install-ghc` subcommands to `stack config set` command. * Add `ghc-build` option to override autodetected GHC build to use (e.g. gmp4, tinfo6, nopie) on Linux. * `stack setup` detects systems where gcc enables PIE by default (such as Ubuntu 16.10 and Hardened Gentoo) and adjusts the GHC `configure` options accordingly. [#2542](https://github.com/commercialhaskell/stack/issues/2542) * Upload to Hackage with HTTP digest instead of HTTP basic. * Make `stack list-dependencies` understand all of the `stack dot` options too. * Add the ability for `stack list-dependencies` to list dependency licenses by passing the `--license` flag. * Dump logs that contain warnings for any local non-dependency packages [#2545](https://github.com/commercialhaskell/stack/issues/2545) * Add the `dump-logs` config option and `--dump-logs` command line option to get full build output on the console. [#426](https://github.com/commercialhaskell/stack/issues/426) * Add the `--open` option to "stack hpc report" command, causing the report to be opened in the browser. * The `stack config set` command now accepts a `--global` flag for suitable subcommands which causes it to modify the global user configuration (`~/.stack/config.yaml`) instead of the project configuration. [#2675](https://github.com/commercialhaskell/stack/pull/2675) * Information on the latest available snapshots is now downloaded from S3 instead of stackage.org, increasing reliability in case of stackage.org outages. [#2653](https://github.com/commercialhaskell/stack/pull/2653) * `stack dot` and `stack list-dependencies` now take targets and flags. [#1919](https://github.com/commercialhaskell/stack/issues/1919) * Deprecate `stack setup --stack-setup-yaml` for `--setup-info-yaml` based on discussion in [#2647](https://github.com/commercialhaskell/stack/issues/2647). * The `--main-is` flag for GHCI now implies the TARGET, fixing [#1845](https://github.com/commercialhaskell/stack/issues/1845). * `stack ghci` no longer takes all build options, as many weren't useful [#2199](https://github.com/commercialhaskell/stack/issues/2199) * `--no-time-in-log` option, to make verbose logs more diffable [#2727](https://github.com/commercialhaskell/stack/issues/2727) * `--color` option added to override auto-detection of ANSI support [#2725](https://github.com/commercialhaskell/stack/issues/2725) * Missing extra-deps are now warned about, adding a degree of typo detection [#1521](https://github.com/commercialhaskell/stack/issues/1521) * No longer warns about missing build-tools if they are on the PATH. [#2235](https://github.com/commercialhaskell/stack/issues/2235) * Replace enclosed-exceptions with safe-exceptions. [#2768](https://github.com/commercialhaskell/stack/issues/2768) * The install location for GHC and other programs can now be configured with the `local-programs-path` option in `config.yaml`. [#1644](https://github.com/commercialhaskell/stack/issues/1644) * Added option to add nix dependencies as nix GC roots * Proper pid 1 (init) process for `stack exec` with Docker * Dump build logs if they contain warnings. [#2545](https://github.com/commercialhaskell/stack/issues/2545) * Docker: redirect stdout of `docker pull` to stderr so that it will not interfere with output of other commands. * Nix & docker can be activated at the same time, in order to run Stack in a nix-shell in a container, preferably from an image already containing the nix dependencies in its /nix/store * Stack/nix: Dependencies can be added as nix GC roots, so they are not removed when running `nix-collect-garbage` Bug fixes: * Fixed a gnarly bug where programs and package tarballs sometimes have corrupted downloads. See [#2657](https://github.com/commercialhaskell/stack/issues/2568). * Add proper support for non-ASCII characters in file paths for the `sdist` command. See [#2549](https://github.com/commercialhaskell/stack/issues/2549) * Never treat `extra-dep` local packages as targets. This ensures things like test suites are not run for these packages, and that build output is not hidden due to their presence. * Fix a resource leak in `sinkProcessStderrStdout` which could affect much of the codebase, in particular copying precompiled packages. [#1979](https://github.com/commercialhaskell/stack/issues/1979) * Docker: ensure that interrupted extraction process does not cause corrupt file when downloading a Docker-compatible Stack executable [#2568](https://github.com/commercialhaskell/stack/issues/2568) * Fixed running `stack hpc report` on package targets. [#2664](https://github.com/commercialhaskell/stack/issues/2664) * Fix a long-standing performance regression where Stack would parse the `.dump-hi` files of the library components of local packages twice. [#2658](https://github.com/commercialhaskell/stack/pull/2658) * Fixed a regression in "stack ghci --no-load", where it would prompt for a main module to load. [#2603](https://github.com/commercialhaskell/stack/pull/2603) * Build Setup.hs files with the threaded RTS, mirroring the behavior of `cabal-install` and enabling more complex build systems in those files. * Fixed a bug in passing along `--ghc-options` to ghcjs. They were being provided as `--ghc-options` to Cabal, when it needs to be `--ghcjs-options`. [#2714](https://github.com/commercialhaskell/stack/issues/2714) * Launch Docker from the project root regardless of the working directory Stack is invoked from. This means paths relative to the project root (e.g. environment files) can be specified in `stack.yaml`'s docker `run-args`. * `stack setup --reinstall` now behaves as expected. [#2554](https://github.com/commercialhaskell/stack/issues/2554) ## 1.2.0 - 2016-09-16 Release notes: * On many Un*x systems, Stack can now be installed with a simple one-liner: wget -qO- https://get.haskellstack.org/ | sh * The fix for [#2175](https://github.com/commercialhaskell/stack/issues/2175) entails that Stack must perform a full clone of a large Git repo of Hackage meta-information. The total download size is about 200 MB. Please be aware of this when upgrading your Stack installation. * If you use Mac OS X, you may want to delay upgrading to macOS Sierra as there are reports of GHC panics when building some packages (including Stack itself). See [#2577](https://github.com/commercialhaskell/stack/issues/2577) * This version of Stack does not build on ARM or PowerPC systems (see [store#37](https://github.com/fpco/store/issues/37)). Please stay with version 1.1.2 for now on those architectures. This will be rectified soon! * We are now releasing a statically-linked Stack executable for [64-bit Linux](https://get.haskellstack.org/stable/linux-x86_64-static.tar.gz). Please try it and let us know if you run into any trouble on your platform. The executable is linked against a version of the GNU Multiple Precision Arithmetic Library (GMP), which is licensed under the GNU Lesser General Public License, Version 3, 29 June 2007 (LGPL). * We are planning some changes to our Linux releases, including dropping our Ubuntu, Debian, CentOS, and Fedora package repositories and switching to statically-linked executables. We would value your feedback in [#2534](https://github.com/commercialhaskell/stack/issues/2534). Major changes: * Add `stack hoogle` command. [#55](https://github.com/commercialhaskell/stack/issues/55) * Support for absolute file path in `url` key of `setup-info` or `--ghc-bindist` * Add support for rendering GHCi scripts targeting different GHCi like applications [#2457](https://github.com/commercialhaskell/stack/pull/2457) Behavior changes: * Remove `stack ide start` and `stack ide load-targets` commands. [#2178](https://github.com/commercialhaskell/stack/issues/2178) * Support .buildinfo files in `stack ghci`. [#2242](https://github.com/commercialhaskell/stack/pull/2242) * Support -ferror-spans syntax in GHC error messages. * Avoid unpacking ghc to `/tmp` [#996](https://github.com/commercialhaskell/stack/issues/996) * The Linux `gmp4` GHC binary distribution is no longer considered a full-fledged GHC variant and can no longer be specified using the `ghc-variant` option, and instead is treated more like a slightly different platform. Other enhancements: * Use the `store` package for binary serialization of most caches. * Only require minor version match for Docker Stack exe. This way, we can make patch releases for version bounds and similar build issues without needing to upload new binaries for Docker. * Stack/Nix: Passes the right ghc derivation as an argument to the `shell.nix` when a custom `shell.nix` is used. See [#2243](https://github.com/commercialhaskell/stack/issues/2243) * Stack/Nix: Sets `LD_LIBRARY_PATH` so packages using C libs for Template Haskell can work (See _e.g._ [this HaskellR issue](https://github.com/tweag/HaskellR/issues/253)) * Parse CLI arguments and configuration files into less permissive types, improving error messages for bad inputs. [#2267](https://github.com/commercialhaskell/stack/issues/2267) * Add the ability to explicitly specify a gcc executable. [#593](https://github.com/commercialhaskell/stack/issues/593) * Nix: No longer uses LTS mirroring in nixpkgs. Gives to nix-shell a derivation like `haskell.compiler.ghc801` See [#2259](https://github.com/commercialhaskell/stack/issues/2259) * Perform some subprocesses during setup concurrently, slightly speeding up most commands. [#2346](https://github.com/commercialhaskell/stack/pull/2346) * `stack setup` no longer unpacks to the system temp dir on posix systems. [#996](https://github.com/commercialhaskell/stack/issues/996) * `stack setup` detects libtinfo6 and ncurses6 and can download alternate GHC binary distributions [#257](https://github.com/commercialhaskell/stack/issues/257) [#2302](https://github.com/commercialhaskell/stack/issues/2302). * `stack setup` detects Linux ARMv7 downloads appropriate GHC binary distribution [#2103](https://github.com/commercialhaskell/stack/issues/2103) * Custom `stack` binaries list dependency versions in output for `--version`. See [#2222](https://github.com/commercialhaskell/stack/issues/2222) and [#2450](https://github.com/commercialhaskell/stack/issues/2450). * Use a pretty printer to output dependency resolution errors. [#1912](https://github.com/commercialhaskell/stack/issues/1912) * Remove the `--os` flag [#2227](https://github.com/commercialhaskell/stack/issues/2227) * Add 'netbase' and 'ca-certificates' as dependency for .deb packages. [#2293](https://github.com/commercialhaskell/stack/issues/2293). * Add `stack ide targets` command. * Enhance debug logging with subprocess timings. * Pretty-print YAML parse errors [#2374](https://github.com/commercialhaskell/stack/issues/2374) * Clarify confusing `stack setup` output [#2314](https://github.com/commercialhaskell/stack/issues/2314) * Delete `Stack.Types` multimodule to improve build times [#2405](https://github.com/commercialhaskell/stack/issues/2405) * Remove spurious newlines in build logs [#2418](https://github.com/commercialhaskell/stack/issues/2418) * Interpreter: Provide a way to hide implicit packages [#1208](https://github.com/commercialhaskell/stack/issues/1208) * Check executability in exec lookup [#2489](https://github.com/commercialhaskell/stack/issues/2489) Bug fixes: * Fix Cabal warning about use of a deprecated Cabal flag [#2350](https://github.com/commercialhaskell/stack/issues/2350) * Support most executable extensions on Windows [#2225](https://github.com/commercialhaskell/stack/issues/2225) * Detect resolver change in `stack solver` [#2252](https://github.com/commercialhaskell/stack/issues/2252) * Fix a bug in docker image creation where the wrong base image was selected [#2376](https://github.com/commercialhaskell/stack/issues/2376) * Ignore special entries when unpacking tarballs [#2361](https://github.com/commercialhaskell/stack/issues/2361) * Fixes src directory pollution of `style.css` and `highlight.js` with GHC 8's haddock [#2429](https://github.com/commercialhaskell/stack/issues/2429) * Handle filepaths with spaces in `stack ghci` [#2266](https://github.com/commercialhaskell/stack/issues/2266) * Apply ghc-options to snapshot packages [#2289](https://github.com/commercialhaskell/stack/issues/2289) * `stack sdist`: Fix timestamp in tarball [#2394](https://github.com/commercialhaskell/stack/pull/2394) * Allow global Stack arguments with a script [#2316](https://github.com/commercialhaskell/stack/issues/2316) * Inconsistency between ToJSON and FromJSON instances of PackageLocation [#2412](https://github.com/commercialhaskell/stack/pull/2412) * Perform Unicode normalization on filepaths [#1810](https://github.com/commercialhaskell/stack/issues/1810) * Solver: always keep ghc wired-in as hard constraints [#2453](https://github.com/commercialhaskell/stack/issues/2453) * Support OpenBSD's tar where possible, require GNU tar for xz support [#2283](https://github.com/commercialhaskell/stack/issues/2283) * Fix using --coverage with Cabal-1.24 [#2424](https://github.com/commercialhaskell/stack/issues/2424) * When marking exe installed, remove old version [#2373](https://github.com/commercialhaskell/stack/issues/2373) * Stop truncating `all-cabal-hashes` git repo [#2175](https://github.com/commercialhaskell/stack/issues/2175) * Handle non-ASCII filenames on Windows [#2491](https://github.com/commercialhaskell/stack/issues/2491) * Avoid using multiple versions of a package in script interpreter by passing package-id to ghc/runghc [#1957](https://github.com/commercialhaskell/stack/issues/1957) * Only pre-load compiler version when using nix integration [#2459](https://github.com/commercialhaskell/stack/issues/2459) * Solver: parse Cabal errors also on Windows [#2502](https://github.com/commercialhaskell/stack/issues/2502) * Allow exec and ghci commands in interpreter mode. Scripts can now automatically open in the repl by using `exec ghci` instead of `runghc` in the shebang command. [#2510](https://github.com/commercialhaskell/stack/issues/2510) * Now consider a package to be dirty when an extra-source-file is changed. See [#2040](https://github.com/commercialhaskell/stack/issues/2040) ## 1.1.2 - 2016-05-20 Release notes: * Official FreeBSD binaries are [now available](http://docs.haskellstack.org/en/stable/install_and_upgrade/#freebsd) [#1253](https://github.com/commercialhaskell/stack/issues/1253). Major changes: * Extensible custom snapshots implemented. These allow you to define snapshots which extend other snapshots. See [#863](https://github.com/commercialhaskell/stack/issues/863). Local file custom snapshots can now be safely updated without changing their name. Remote custom snapshots should still be treated as immutable. Behavior changes: * `stack path --compiler` was added in the last release, to yield a path to the compiler. Unfortunately, `--compiler` is a global option that is useful to use with `stack path`. The same functionality is now provided by `stack path --compiler-exe`. See [#2123](https://github.com/commercialhaskell/stack/issues/2123) * For packages specified in terms of a git or hg repo, the hash used in the location has changed. This means that existing downloads from older stack versions won't be used. This is a side-effect of the fix to [#2133](https://github.com/commercialhaskell/stack/issues/2133) * `stack upgrade` no longer pays attention to local `stack.yaml` files, just the global config and CLI options. [#1392](https://github.com/commercialhaskell/stack/issues/1392) * `stack ghci` now uses `:add` instead of `:load`, making it potentially work better with user scripts. See [#1888](https://github.com/commercialhaskell/stack/issues/1888) Other enhancements: * Grab Cabal files via Git SHA to avoid regressions from Hackage revisions [#2070](https://github.com/commercialhaskell/stack/pull/2070) * Custom snapshots now support `ghc-options`. * Package git repos are now re-used rather than re-cloned. See [#1620](https://github.com/commercialhaskell/stack/issues/1620) * `DESTDIR` is filtered from environment when installing GHC. See [#1460](https://github.com/commercialhaskell/stack/issues/1460) * `stack haddock` now supports `--haddock-arguments`. See [#2144](https://github.com/commercialhaskell/stack/issues/2144) * Signing: warn if GPG_TTY is not set as per `man gpg-agent` Bug fixes: * Now ignore project config when doing `stack init` or `stack new`. See [#2110](https://github.com/commercialhaskell/stack/issues/2110) * Packages specified by git repo can now have submodules. See [#2133](https://github.com/commercialhaskell/stack/issues/2133) * Fix of hackage index fetch retry. See re-opening of [#1418](https://github.com/commercialhaskell/stack/issues/1418#issuecomment-217633843) * HPack now picks up changes to filesystem other than package.yaml. See [#2051](https://github.com/commercialhaskell/stack/issues/2051) * "stack solver" no longer suggests --omit-packages. See [#2031](https://github.com/commercialhaskell/stack/issues/2031) * Fixed an issue with building Cabal's Setup.hs. See [#1356](https://github.com/commercialhaskell/stack/issues/1356) * Package dirtiness now pays attention to deleted files. See [#1841](https://github.com/commercialhaskell/stack/issues/1841) * `stack ghci` now uses `extra-lib-dirs` and `extra-include-dirs`. See [#1656](https://github.com/commercialhaskell/stack/issues/1656) * Relative paths outside of source dir added via `qAddDependentFile` are now checked for dirtiness. See [#1982](https://github.com/commercialhaskell/stack/issues/1982) * Signing: always use `--with-fingerprints` ## 1.1.0 - 2016-05-04 Release notes: * Added Ubuntu 16.04 LTS (xenial) Apt repo. * No longer uploading new versions to Fedora 21 repo. Behavior changes: * Snapshot packages are no longer built with executable profiling. See [#1179](https://github.com/commercialhaskell/stack/issues/1179). * `stack init` now ignores symlinks when searching for Cabal files. It also now ignores any directory that begins with `.` (as well as `dist` dirs) - before it would only ignore `.git`, `.stack-work`, and `dist`. * The Stack executable is no longer built with `-rtsopts`. Before, when `-rtsopts` was enabled, Stack would process `+RTS` options even when intended for some other program, such as when used with `stack exec -- prog +RTS`. See [#2022](https://github.com/commercialhaskell/stack/issues/2022). * The `stack path --ghc-paths` option is deprecated and renamed to `--programs`. `--compiler` is added, which points directly at the compiler used in the current project. `--compiler-bin` points to the compiler's bin dir. * For consistency with the `$STACK_ROOT` environment variable, the `stack path --global-stack-root` flag and the `global-stack-root` field in the output of `stack path` are being deprecated and replaced with the `stack-root` flag and output field. Additionally, the Stack root can now be specified via the `--stack-root` command-line flag. See [#1148](https://github.com/commercialhaskell/stack/issues/1148). * `stack sig` GPG-related sub-commands were removed (folded into `upload` and `sdist`) * GPG signing of packages while uploading to Hackage is now the default. Use `upload --no-signature` if you would rather not contribute your package signature. If you don't yet have a GPG keyset, read this [blog post on GPG keys](https://fpcomplete.com/blog/2016/05/stack-security-gnupg-keys). We can add a `stack.yaml` config setting to disable signing if some people desire it. We hope that people will sign. Later we will be adding GPG signature verification options. * `stack build pkg-1.2.3` will now build even if the snapshot has a different package version - it is treated as an extra-dep. `stack build local-pkg-1.2.3` is an error even if the version number matches the local package [#2028](https://github.com/commercialhaskell/stack/issues/2028). * A `nix` key in a Stack YAML configuration file no longer implies enabling a Nix build. This allows the user to globally configure whether Nix is used (unless the project overrides the default explicitly). See [#1924](https://github.com/commercialhaskell/stack/issues/1924). * Remove deprecated `valid-wanted` key. * Docker: mount home directory in container [#1949](https://github.com/commercialhaskell/stack/issues/1949). * Deprecate `stack path --local-bin-path`; instead use `--local-bin`. * `stack image`: allow absolute source paths for `add`. Other enhancements: * `stack haddock --open [PACKAGE]` opens the local haddocks in the browser. * Fix too much rebuilding when enabling/disabling profiling flags. * `stack build pkg-1.0` will now build `pkg-1.0` even if the snapshot specifies a different version (it introduces a temporary extra-dep) * Experimental: Support for `--split-objs` added [#1284](https://github.com/commercialhaskell/stack/issues/1284). * `git` packages with submodules are supported by passing the `--recursive` flag to `git clone`. * When using [Hpack](https://github.com/sol/hpack), only regenerate Cabal files when Hpack files change. * Hpack files can now be used in templates * `stack ghci` now runs ghci as a separate process [#1306](https://github.com/commercialhaskell/stack/issues/1306) * Retry when downloading snapshots and package indices * Many build options are configurable now in `stack.yaml`: ~~~yaml build: library-profiling: true executable-profiling: true haddock: true haddock-deps: true copy-bins: true prefetch: true force-dirty: true keep-going: true test: true test-arguments: rerun-tests: true additional-args: ['-fprof'] coverage: true no-run-tests: true bench: true benchmark-opts: benchmark-arguments: -O2 no-run-benchmarks: true reconfigure: true cabal-verbose: true ~~~ * A number of URLs are now configurable, useful for firewalls. See [#1794](https://github.com/commercialhaskell/stack/issues/1884). * Suggest causes when executables are missing. * Allow `--omit-packages` even without `--solver`. * Improve the generated `stack.yaml`. * Improve ghci results after :load Main module collision with main file path. * Only load the hackage index if necessary [#1883](https://github.com/commercialhaskell/stack/issues/1883), [#1892](https://github.com/commercialhaskell/stack/issues/1892). * init: allow local packages to be deps of deps [#1965](https://github.com/commercialhaskell/stack/issues/1965). * Always use full fingerprints from GPG [#1952](https://github.com/commercialhaskell/stack/issues/1952). * Default to using `gpg2` and fall back to `gpg` [#1976](https://github.com/commercialhaskell/stack/issues/1976). * Add a flag for --verbosity silent. * Add `haddock --open` flag [#1396](https://github.com/commercialhaskell/stack/issues/1396). Bug fixes: * Package tarballs would fail to unpack. [#1884](https://github.com/commercialhaskell/stack/issues/1884). * Fixed errant warnings about missing modules, after deleted and removed from Cabal file [#921](https://github.com/commercialhaskell/stack/issues/921) [#1805](https://github.com/commercialhaskell/stack/issues/1805). * Now considers a package to dirty when the Hpack file is changed [#1819](https://github.com/commercialhaskell/stack/issues/1819). * Nix: cancelling a Stack build now exits properly rather than dropping into a nix-shell [#1778](https://github.com/commercialhaskell/stack/issues/1778). * `allow-newer: true` now causes `--exact-configuration` to be passed to Cabal. See [#1579](https://github.com/commercialhaskell/stack/issues/1579). * `stack solver` no longer fails with `InvalidRelFile` for relative package paths including `..`. See [#1954](https://github.com/commercialhaskell/stack/issues/1954). * Ignore emacs lock files when finding Cabal files [#1897](https://github.com/commercialhaskell/stack/issues/1897). * Use lenient UTF-8 decode for build output [#1945](https://github.com/commercialhaskell/stack/issues/1945). * Clear index cache whenever index updated [#1962](https://github.com/commercialhaskell/stack/issues/1962). * Fix: Building a container image drops a .stack-work dir in the current working (sub)directory [#1975](https://github.com/commercialhaskell/stack/issues/1975). * Fix: Rebuilding when disabling profiling [#2023](https://github.com/commercialhaskell/stack/issues/2023). ## 1.0.4.3 - 2016-04-07 Bug fixes: * Don't delete contents of ~/.ssh when using `stack clean --full` with Docker enabled [#2000](https://github.com/commercialhaskell/stack/issues/2000) ## 1.0.4.2 - 2016-03-09 Build with `path-io-1.0.0`. There are no changes in behaviour from 1.0.4, so no binaries are released for this version. ## 1.0.4.1 - 2016-02-21 Fixes build with `aeson-0.11.0.0`. There are no changes in behaviour from 1.0.4, so no binaries are released for this version. ## 1.0.4 - 2016-02-20 Major changes: * Some notable changes in `stack init`: * Overall it should now be able to initialize almost all existing Cabal packages out of the box as long as the package itself is consistently defined. * Choose the best possible snapshot and add extra-deps on top of a snapshot other than a compiler snapshot - [#1583](https://github.com/commercialhaskell/stack/pull/1583) * Automatically omit a package (`--omit-packages`) when it is compiler incompatible or when there are packages with conflicting dependency requirements. See [#1674](https://github.com/commercialhaskell/stack/pull/1674). * Some more changes for a better user experience. Please refer to the doc guide for details. * Add support for Hpack, alternative package description format [#1679](https://github.com/commercialhaskell/stack/issues/1679) Other enhancements: * Docker: pass ~/.ssh and SSH auth socket into container, so that git repos work [#1358](https://github.com/commercialhaskell/stack/issues/1358). * Docker: strip suffix from docker --version. [#1653](https://github.com/commercialhaskell/stack/issues/1653) * Docker: pass USER and PWD environment variables into container. * On each run, Stack will test the Stack root directory (~/.stack), and the project and package work directories (.stack-work) for whether they are owned by the current user and abort if they are not. This precaution can be disabled with the `--allow-different-user` flag or `allow-different-user` option in the global config (~/.stack/config.yaml). [#471](https://github.com/commercialhaskell/stack/issues/471) * Added `stack clean --full` option for full working dir cleanup. * YAML config: support Zip archives. * Redownload build plan if parsing fails [#1702](https://github.com/commercialhaskell/stack/issues/1702). * Give mustache templates access to a 'year' tag [#1716](https://github.com/commercialhaskell/stack/pull/1716). * Have "stack ghci" warn about module name aliasing. * Add "stack ghci --load-local-deps". * Build Setup.hs with -rtsopts [#1687](https://github.com/commercialhaskell/stack/issues/1687). * `stack init` accepts a list of directories. * Add flag infos to DependencyPlanFailures (for better error output in case of flags) [#713](https://github.com/commercialhaskell/stack/issues/713) * `stack new --bare` complains for overwrites, and add `--force` option [#1597](https://github.com/commercialhaskell/stack/issues/1597). Bug fixes: * Previously, `stack ghci` would fail with `cannot satisfy -package-id` when the implicit build step changes the package key of some dependency. * Fix: Building with ghcjs: "ghc-pkg: Prelude.chr: bad argument: 2980338" [#1665](https://github.com/commercialhaskell/stack/issues/1665). * Fix running test / bench with `--profile` / `--trace`. * Fix: build progress counter is no longer visible [#1685](https://github.com/commercialhaskell/stack/issues/1685). * Use "-RTS" w/ profiling to allow extra args [#1772](https://github.com/commercialhaskell/stack/issues/1772). * Fix withUnpackedTarball7z to find name of srcDir after unpacking (fixes `stack setup` fails for ghcjs project on windows) [#1774](https://github.com/commercialhaskell/stack/issues/1774). * Add space before auto-generated bench opts (makes profiling options work uniformly for applications and benchmark suites) [#1771](https://github.com/commercialhaskell/stack/issues/1771). * Don't try to find plugin if it resembles flag. * Setup.hs changes cause package dirtiness [#1711](https://github.com/commercialhaskell/stack/issues/1711). * Send "stack templates" output to stdout [#1792](https://github.com/commercialhaskell/stack/issues/1792). ## 1.0.2 - 2016-01-18 Release notes: - Arch Linux: Stack has been adopted into the [official community repository](https://www.archlinux.org/packages/community/x86_64/stack/), so we will no longer be updating the AUR with new versions. See the [install/upgrade guide](http://docs.haskellstack.org/en/stable/install_and_upgrade/#arch-linux) for current download instructions. Major changes: - `stack init` and `solver` overhaul [#1583](https://github.com/commercialhaskell/stack/pull/1583) Other enhancements: - Disable locale/codepage hacks when GHC >=7.10.3 [#1552](https://github.com/commercialhaskell/stack/issues/1552) - Specify multiple images to build for `stack image container` [docs](http://docs.haskellstack.org/en/stable/yaml_configuration/#image) - Specify which executables to include in images for `stack image container` [docs](http://docs.haskellstack.org/en/stable/yaml_configuration/#image) - Docker: pass supplementary groups and umask into container - If git fetch fails wipe the directory and try again from scratch [#1418](https://github.com/commercialhaskell/stack/issues/1418) - Warn if newly installed executables won't be available on the PATH [#1362](https://github.com/commercialhaskell/stack/issues/1362) - `stack.yaml`: for `stack image container`, specify multiple images to generate, and which executables should be added to those images - GHCI: add interactive Main selection [#1068](https://github.com/commercialhaskell/stack/issues/1068) - Care less about the particular name of a GHCJS sdist folder [#1622](https://github.com/commercialhaskell/stack/issues/1622) - Unified Enable/disable help messaging [#1613](https://github.com/commercialhaskell/stack/issues/1613) Bug fixes: - Don't share precompiled packages between GHC/platform variants and Docker [#1551](https://github.com/commercialhaskell/stack/issues/1551) - Properly redownload corrupted downloads with the correct file size. [Mailing list discussion](https://groups.google.com/d/msg/haskell-stack/iVGDG5OHYxs/FjUrR5JsDQAJ) - Gracefully handle invalid paths in error/warning messages [#1561](https://github.com/commercialhaskell/stack/issues/1561) - Nix: select the correct GHC version corresponding to the snapshot even when an abstract resolver is passed via `--resolver` on the command-line. [#1641](https://github.com/commercialhaskell/stack/issues/1641) - Fix: Stack does not allow using an external package from ghci [#1557](https://github.com/commercialhaskell/stack/issues/1557) - Disable ambiguous global '--resolver' option for 'stack init' [#1531](https://github.com/commercialhaskell/stack/issues/1531) - Obey `--no-nix` flag - Fix: GHCJS Execute.hs: Non-exhaustive patterns in lambda [#1591](https://github.com/commercialhaskell/stack/issues/1591) - Send file-watch and sticky logger messages to stderr [#1302](https://github.com/commercialhaskell/stack/issues/1302) [#1635](https://github.com/commercialhaskell/stack/issues/1635) - Use globaldb path for querying Cabal version [#1647](https://github.com/commercialhaskell/stack/issues/1647) ## 1.0.0 - 2015-12-24 Release notes: * We're calling this version 1.0.0 in preparation for Stackage LTS 4. Note, however, that this does not mean the code's API will be stable as this is primarily an end-user tool. Enhancements: * Added flag `--profile` flag: passed with `stack build`, it will enable profiling, and for `--bench` and `--test` it will generate a profiling report by passing `+RTS -p` to the executable(s). Great for using like `stack build --bench --profile` (remember that enabling profile will slow down your benchmarks by >4x). Run `stack build --bench` again to disable the profiling and get proper speeds * Added flag `--trace` flag: just like `--profile`, it enables profiling, but instead of generating a report for `--bench` and `--test`, prints out a stack trace on exception. Great for using like `stack build --test --trace` * Nix: all options can be overridden on command line [#1483](https://github.com/commercialhaskell/stack/issues/1483) * Nix: build environments (shells) are now pure by default. * Make verbosity silent by default in script interpreter mode [#1472](https://github.com/commercialhaskell/stack/issues/1472) * Show a message when resetting git commit fails [#1453](https://github.com/commercialhaskell/stack/issues/1453) * Improve Unicode handling in project/package names [#1337](https://github.com/commercialhaskell/stack/issues/1337) * Fix ambiguity between a Stack command and a filename to execute (prefer `stack` subcommands) [#1471](https://github.com/commercialhaskell/stack/issues/1471) * Support multi line interpreter directive comments [#1394](https://github.com/commercialhaskell/stack/issues/1394) * Handle space separated pids in ghc-pkg dump (for GHC HEAD) [#1509](https://github.com/commercialhaskell/stack/issues/1509) * Add ghci --no-package-hiding option [#1517](https://github.com/commercialhaskell/stack/issues/1517) * `stack new` can download templates from URL [#1466](https://github.com/commercialhaskell/stack/issues/1466) Bug fixes: * Nix: `stack exec` options are passed properly to the Stack sub process [#1538](https://github.com/commercialhaskell/stack/issues/1538) * Nix: specifying a shell-file works in any current working directory [#1547](https://github.com/commercialhaskell/stack/issues/1547) * Nix: use `--resolver` argument * Docker: fix missing image message and '--docker-auto-pull' * No HTML escaping for "stack new" template params [#1475](https://github.com/commercialhaskell/stack/issues/1475) * Set permissions for generated .ghci script [#1480](https://github.com/commercialhaskell/stack/issues/1480) * Restrict commands allowed in interpreter mode [#1504](https://github.com/commercialhaskell/stack/issues/1504) * `stack ghci` doesn't see preprocessed files for executables [#1347](https://github.com/commercialhaskell/stack/issues/1347) * All test suites run even when only one is requested [#1550](https://github.com/commercialhaskell/stack/pull/1550) * Edge cases in broken templates give odd errors [#1535](https://github.com/commercialhaskell/stack/issues/1535) * Fix test coverage bug on windows ## 0.1.10.1 - 2015-12-13 Bug fixes: * `stack image container` did not actually build an image [#1473](https://github.com/commercialhaskell/stack/issues/1473) ## 0.1.10.0 - 2015-12-04 Release notes: * The Stack home page is now at [haskellstack.org](http://haskellstack.org), which shows the documentation rendered by readthedocs.org. Note: this has necessitated some changes to the links in the documentation's markdown source code, so please check the links on the website before submitting a PR to fix them. * The locations of the [Ubuntu](http://docs.haskellstack.org/en/stable/install_and_upgrade/#ubuntu) and [Debian](http://docs.haskellstack.org/en/stable/install_and_upgrade/#debian) package repositories have changed to have correct URL semantics according to Debian's guidelines [#1378](https://github.com/commercialhaskell/stack/issues/1378). The old locations will continue to work for some months, but we suggest that you adjust your `/etc/apt/sources.list.d/fpco.list` to the new location to avoid future disruption. * [openSUSE and SUSE Linux Enterprise](http://docs.haskellstack.org/en/stable/install_and_upgrade/#suse) packages are now available, thanks to [@mimi1vx](https://github.com/mimi1vx). Note: there will be some lag before these pick up new versions, as they are based on Stackage LTS. Major changes: * Support for building inside a Nix-shell providing system dependencies [#1285](https://github.com/commercialhaskell/stack/pull/1285) * Add optional GPG signing on `stack upload --sign` or with `stack sig sign ...` Other enhancements: * Print latest applicable version of packages on conflicts [#508](https://github.com/commercialhaskell/stack/issues/508) * Support for packages located in Mercurial repositories [#1397](https://github.com/commercialhaskell/stack/issues/1397) * Only run benchmarks specified as build targets [#1412](https://github.com/commercialhaskell/stack/issues/1412) * Support git-style executable fall-through (`stack something` executes `stack-something` if present) [#1433](https://github.com/commercialhaskell/stack/issues/1433) * GHCi now loads intermediate dependencies [#584](https://github.com/commercialhaskell/stack/issues/584) * `--work-dir` option for overriding `.stack-work` [#1178](https://github.com/commercialhaskell/stack/issues/1178) * Support `detailed-0.9` tests [#1429](https://github.com/commercialhaskell/stack/issues/1429) * Docker: improved POSIX signal proxying to containers [#547](https://github.com/commercialhaskell/stack/issues/547) Bug fixes: * Show absolute paths in error messages in multi-package builds [#1348](https://github.com/commercialhaskell/stack/issues/1348) * Docker-built binaries and libraries in different path [#911](https://github.com/commercialhaskell/stack/issues/911) [#1367](https://github.com/commercialhaskell/stack/issues/1367) * Docker: `--resolver` argument didn't effect selected image tag * GHCi: Spaces in filepaths caused module loading issues [#1401](https://github.com/commercialhaskell/stack/issues/1401) * GHCi: cpp-options in Cabal files weren't used [#1419](https://github.com/commercialhaskell/stack/issues/1419) * Benchmarks couldn't be run independently of each other [#1412](https://github.com/commercialhaskell/stack/issues/1412) * Send output of building setup to stderr [#1410](https://github.com/commercialhaskell/stack/issues/1410) ## 0.1.8.0 - 2015-11-20 Major changes: * GHCJS can now be used with stackage snapshots via the new `compiler` key. * Windows installers are now available: [download them here](http://docs.haskellstack.org/en/stable/install_and_upgrade/#windows) [#613](https://github.com/commercialhaskell/stack/issues/613) * Docker integration works with non-FPComplete generated images [#531](https://github.com/commercialhaskell/stack/issues/531) Other enhancements: * Added an `allow-newer` config option [#922](https://github.com/commercialhaskell/stack/issues/922) [#770](https://github.com/commercialhaskell/stack/issues/770) * When a Hackage revision invalidates a build plan in a snapshot, trust the snapshot [#770](https://github.com/commercialhaskell/stack/issues/770) * Added a `stack config set resolver RESOLVER` command. Part of work on [#115](https://github.com/commercialhaskell/stack/issues/115) * `stack setup` can now install GHCJS on windows. See [#1145](https://github.com/commercialhaskell/stack/issues/1145) and [#749](https://github.com/commercialhaskell/stack/issues/749) * `stack hpc report` command added, which generates reports for HPC tix files * `stack ghci` now accepts all the flags accepted by `stack build`. See [#1186](https://github.com/commercialhaskell/stack/issues/1186) * `stack ghci` builds the project before launching GHCi. If the build fails, try to launch GHCi anyway. Use `stack ghci --no-build` option to disable [#1065](https://github.com/commercialhaskell/stack/issues/1065) * `stack ghci` now detects and warns about various circumstances where it is liable to fail. See [#1270](https://github.com/commercialhaskell/stack/issues/1270) * Added `require-docker-version` configuration option * Packages will now usually be built along with their tests and benchmarks. See [#1166](https://github.com/commercialhaskell/stack/issues/1166) * Relative `local-bin-path` paths will be relative to the project's root directory, not the current working directory. [#1340](https://github.com/commercialhaskell/stack/issues/1340) * `stack clean` now takes an optional `[PACKAGE]` argument for use in multi-package projects. See [#583](https://github.com/commercialhaskell/stack/issues/583) * Ignore cabal_macros.h as a dependency [#1195](https://github.com/commercialhaskell/stack/issues/1195) * Pad timestamps and show local time in --verbose output [#1226](https://github.com/commercialhaskell/stack/issues/1226) * GHCi: Import all modules after loading them [#995](https://github.com/commercialhaskell/stack/issues/995) * Add subcommand aliases: `repl` for `ghci`, and `runhaskell` for `runghc` [#1241](https://github.com/commercialhaskell/stack/issues/1241) * Add typo recommendations for unknown package identifiers [#158](https://github.com/commercialhaskell/stack/issues/158) * Add `stack path --local-hpc-root` option * Overhaul dependencies' haddocks copying [#1231](https://github.com/commercialhaskell/stack/issues/1231) * Support for extra-package-dbs in 'stack ghci' [#1229](https://github.com/commercialhaskell/stack/pull/1229) * `stack new` disallows package names with "words" consisting solely of numbers [#1336](https://github.com/commercialhaskell/stack/issues/1336) * `stack build --fast` turns off optimizations * Show progress while downloading package index [#1223](https://github.com/commercialhaskell/stack/issues/1223). Bug fixes: * Fix: Haddocks not copied for dependencies [#1105](https://github.com/commercialhaskell/stack/issues/1105) * Fix: Global options did not work consistently after subcommand [#519](https://github.com/commercialhaskell/stack/issues/519) * Fix: 'stack ghci' doesn't notice that a module got deleted [#1180](https://github.com/commercialhaskell/stack/issues/1180) * Rebuild when Cabal file is changed * Fix: Paths in GHC warnings not canonicalized, nor those for packages in subdirectories or outside the project root [#1259](https://github.com/commercialhaskell/stack/issues/1259) * Fix: unlisted files in tests and benchmarks trigger extraneous second build [#838](https://github.com/commercialhaskell/stack/issues/838) ## 0.1.6.0 - 2015-10-15 Major changes: * `stack setup` now supports building and booting GHCJS from source tarball. * On Windows, build directories no longer display "pretty" information (like x86_64-windows/Cabal-1.22.4.0), but rather a hash of that content. The reason is to avoid the 260 character path limitation on Windows. See [#1027](https://github.com/commercialhaskell/stack/pull/1027) * Rename config files and clarify their purposes [#969](https://github.com/commercialhaskell/stack/issues/969) * `~/.stack/stack.yaml` --> `~/.stack/config.yaml` * `~/.stack/global` --> `~/.stack/global-project` * `/etc/stack/config` --> `/etc/stack/config.yaml` * Old locations still supported, with deprecation warnings * New command "stack eval CODE", which evaluates to "stack exec ghc -- -e CODE". Other enhancements: * No longer install `git` on Windows [#1046](https://github.com/commercialhaskell/stack/issues/1046). You can still get this behavior by running the following yourself: `stack exec -- pacman -Sy --noconfirm git`. * Typing enter during --file-watch triggers a rebuild [#1023](https://github.com/commercialhaskell/stack/pull/1023) * Use Haddock's `--hyperlinked-source` (crosslinked source), if available [#1070](https://github.com/commercialhaskell/stack/pull/1070) * Use Stack-installed GHCs for `stack init --solver` [#1072](https://github.com/commercialhaskell/stack/issues/1072) * Experimental: Add `stack query` command [#1087](https://github.com/commercialhaskell/stack/issues/1087) * By default, Stack no longer rebuilds a package due to GHC options changes. This behavior can be tweaked with the `rebuild-ghc-options` setting. [#1089](https://github.com/commercialhaskell/stack/issues/1089) * By default, ghc-options are applied to all local packages, not just targets. This behavior can be tweaked with the `apply-ghc-options` setting. [#1089](https://github.com/commercialhaskell/stack/issues/1089) * Docker: download or override location of Stack executable to re-run in container [#974](https://github.com/commercialhaskell/stack/issues/974) * Docker: when Docker Engine is remote, don't run containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194) * Docker: `set-user` option to enable/disable running containerized processes as host's UID/GID [#194](https://github.com/commercialhaskell/stack/issues/194) * Custom Setup.hs files are now precompiled instead of interpreted. This should be a major performance win for certain edge cases (biggest example: [building Cabal itself](https://github.com/commercialhaskell/stack/issues/1041)) while being either neutral or a minor slowdown for more common cases. * `stack test --coverage` now also generates a unified coverage report for multiple test-suites / packages. In the unified report, test-suites can contribute to the coverage of other packages. Bug fixes: * Ignore stack-built executables named `ghc` [#1052](https://github.com/commercialhaskell/stack/issues/1052) * Fix quoting of output failed command line arguments * Mark executable-only packages as installed when copied from cache [#1043](https://github.com/commercialhaskell/stack/pull/1043) * Canonicalize temporary directory paths [#1047](https://github.com/commercialhaskell/stack/pull/1047) * Put code page fix inside the build function itself [#1066](https://github.com/commercialhaskell/stack/issues/1066) * Add `explicit-setup-deps` option [#1110](https://github.com/commercialhaskell/stack/issues/1110), and change the default to the old behavior of using any package in the global and snapshot database [#1025](https://github.com/commercialhaskell/stack/issues/1025) * Precompiled cache checks full package IDs on Cabal < 1.22 [#1103](https://github.com/commercialhaskell/stack/issues/1103) * Pass -package-id to ghci [#867](https://github.com/commercialhaskell/stack/issues/867) * Ignore global packages when copying precompiled packages [#1146](https://github.com/commercialhaskell/stack/issues/1146) ## 0.1.5.0 - 2015-09-24 Major changes: * On Windows, we now use a full MSYS2 installation in place of the previous PortableGit. This gives you access to the pacman package manager for more easily installing libraries. * Support for custom GHC binary distributions [#530](https://github.com/commercialhaskell/stack/issues/530) * `ghc-variant` option in `stack.yaml` to specify the variant (also `--ghc-variant` command-line option) * `setup-info` in `stack.yaml`, to specify where to download custom binary distributions (also `--ghc-bindist` command-line option) * Note: On systems with libgmp4 (aka `libgmp.so.3`), such as CentOS 6, you may need to re-run `stack setup` due to the centos6 GHC binary distribution being treated like a variant * A new `--pvp-bounds` flag to the sdist and upload commands allows automatic adding of PVP upper and/or lower bounds to your dependencies Other enhancements: * Adapt to upcoming Cabal installed package identifier format change [#851](https://github.com/commercialhaskell/stack/issues/851) * `stack setup` takes a `--stack-setup-yaml` argument * `--file-watch` is more discerning about which files to rebuild for [#912](https://github.com/commercialhaskell/stack/issues/912) * `stack path` now supports `--global-pkg-db` and `--ghc-package-path` * `--reconfigure` flag [#914](https://github.com/commercialhaskell/stack/issues/914) [#946](https://github.com/commercialhaskell/stack/issues/946) * Cached data is written with a checksum of its structure [#889](https://github.com/commercialhaskell/stack/issues/889) * Fully removed `--optimizations` flag * Added `--cabal-verbose` flag * Added `--file-watch-poll` flag for polling instead of using filesystem events (useful for running tests in a Docker container while modifying code in the host environment. When code is injected into the container via a volume, the container won't propagate filesystem events). * Give a preemptive error message when `-prof` is given as a GHC option [#1015](https://github.com/commercialhaskell/stack/issues/1015) * Locking is now optional, and will be turned on by setting the `STACK_LOCK` environment variable to `true` [#950](https://github.com/commercialhaskell/stack/issues/950) * Create default `stack.yaml` with documentation comments and commented out options [#226](https://github.com/commercialhaskell/stack/issues/226) * Out of memory warning if Cabal exits with -9 [#947](https://github.com/commercialhaskell/stack/issues/947) Bug fixes: * Hacky workaround for optparse-applicative issue with `stack exec --help` [#806](https://github.com/commercialhaskell/stack/issues/806) * Build executables for local extra-deps [#920](https://github.com/commercialhaskell/stack/issues/920) * copyFile can't handle directories [#942](https://github.com/commercialhaskell/stack/pull/942) * Support for spaces in Haddock interface files [fpco/minghc#85](https://github.com/fpco/minghc/issues/85) * Temporarily building against a "shadowing" local package? [#992](https://github.com/commercialhaskell/stack/issues/992) * Fix `Setup.exe` name for `--upgrade-cabal` on Windows [#1002](https://github.com/commercialhaskell/stack/issues/1002) * Unlisted dependencies no longer trigger extraneous second build [#838](https://github.com/commercialhaskell/stack/issues/838) ## 0.1.4.1 - 2015-09-04 Fix stack's own Haddocks. No changes to functionality (only comments updated). ## 0.1.4.0 - 2015-09-04 Major changes: * You now have more control over how GHC versions are matched, e.g. "use exactly this version," "use the specified minor version, but allow patches," or "use the given minor version or any later minor in the given major release." The default has switched from allowing newer later minor versions to a specific minor version allowing patches. For more information, see [#736](https://github.com/commercialhaskell/stack/issues/736) and [#784](https://github.com/commercialhaskell/stack/pull/784). * Support added for compiling with GHCJS * Stack can now reuse prebuilt binaries between snapshots. That means that, if you build package foo in LTS-3.1, that binary version can be reused in LTS-3.2, assuming it uses the same dependencies and flags. [#878](https://github.com/commercialhaskell/stack/issues/878) Other enhancements: * Added the `--docker-env` argument, to set environment variables in Docker container. * Set locale environment variables to UTF-8 encoding for builds to avoid "commitBuffer: invalid argument" errors from GHC [#793](https://github.com/commercialhaskell/stack/issues/793) * Enable transliteration for encoding on stdout and stderr [#824](https://github.com/commercialhaskell/stack/issues/824) * By default, `stack upgrade` automatically installs GHC as necessary [#797](https://github.com/commercialhaskell/stack/issues/797) * Added the `ghc-options` key to `stack.yaml` [#796](https://github.com/commercialhaskell/stack/issues/796) * Added the `extra-path` key to `stack.yaml` * Code page changes on Windows only apply to the build command (and its synonyms), and can be controlled via a command line flag (still defaults to on) [#757](https://github.com/commercialhaskell/stack/issues/757) * Implicitly add packages to extra-deps when a flag for them is set [#807](https://github.com/commercialhaskell/stack/issues/807) * Use a precompiled Setup.hs for simple build types [#801](https://github.com/commercialhaskell/stack/issues/801) * Set --enable-tests and --enable-benchmarks optimistically [#805](https://github.com/commercialhaskell/stack/issues/805) * `--only-configure` option added [#820](https://github.com/commercialhaskell/stack/issues/820) * Check for duplicate local package names * Stop nagging people that call `stack test` [#845](https://github.com/commercialhaskell/stack/issues/845) * `--file-watch` will ignore files that are in your VCS boring/ignore files [#703](https://github.com/commercialhaskell/stack/issues/703) * Add `--numeric-version` option Bug fixes: * `stack init --solver` fails if `GHC_PACKAGE_PATH` is present [#860](https://github.com/commercialhaskell/stack/issues/860) * `stack solver` and `stack init --solver` check for test suite and benchmark dependencies [#862](https://github.com/commercialhaskell/stack/issues/862) * More intelligent logic for setting UTF-8 locale environment variables [#856](https://github.com/commercialhaskell/stack/issues/856) * Create missing directories for `stack sdist` * Don't ignore Cabal files with extra periods [#895](https://github.com/commercialhaskell/stack/issues/895) * Deprecate unused `--optimizations` flag * Truncated output on slow terminals [#413](https://github.com/commercialhaskell/stack/issues/413) ## 0.1.3.1 - 2015-08-12 Bug fixes: * Ignore disabled executables [#763](https://github.com/commercialhaskell/stack/issues/763) ## 0.1.3.0 - 2015-08-12 Major changes: * Detect when a module is compiled but not listed in the Cabal file ([#32](https://github.com/commercialhaskell/stack/issues/32)) * A warning is displayed for any modules that should be added to `other-modules` in the Cabal file * These modules are taken into account when determining whether a package needs to be built * Respect TemplateHaskell addDependentFile dependency changes ([#105](https://github.com/commercialhaskell/stack/issues/105)) * TH dependent files are taken into account when determining whether a package needs to be built. * Overhauled target parsing, added `--test` and `--bench` options [#651](https://github.com/commercialhaskell/stack/issues/651) * For details, see [Build commands documentation](http://docs.haskellstack.org/en/stable/build_command/) Other enhancements: * Set the `HASKELL_DIST_DIR` environment variable [#524](https://github.com/commercialhaskell/stack/pull/524) * Track build status of tests and benchmarks [#525](https://github.com/commercialhaskell/stack/issues/525) * `--no-run-tests` [#517](https://github.com/commercialhaskell/stack/pull/517) * Targets outside of root dir don't build [#366](https://github.com/commercialhaskell/stack/issues/366) * Upper limit on number of flag combinations to test [#543](https://github.com/commercialhaskell/stack/issues/543) * Fuzzy matching support to give better error messages for close version numbers [#504](https://github.com/commercialhaskell/stack/issues/504) * `--local-bin-path` global option.

2015-07-05 * Add `--prune` flag to `stack dot` [#487](https://github.com/commercialhaskell/stack/issues/487) * Add `--[no-]external`,`--[no-]include-base` flags to `stack dot` [#437](https://github.com/commercialhaskell/stack/issues/437) * Add `--ignore-subdirs` flag to init command [#435](https://github.com/commercialhaskell/stack/pull/435) * Handle attempt to use non-existing resolver [#436](https://github.com/commercialhaskell/stack/pull/436) * Add `--force` flag to `init` command * exec style commands accept the `--package` option (see [Reddit discussion](http://www.reddit.com/r/haskell/comments/3bd66h/stack_runghc_turtle_as_haskell_script_solution/)) * `stack upload` without arguments doesn't do anything [#439](https://github.com/commercialhaskell/stack/issues/439) * Print latest version of packages on conflicts [#450](https://github.com/commercialhaskell/stack/issues/450) * Flag to avoid rerunning tests that haven't changed [#451](https://github.com/commercialhaskell/stack/issues/451) * Stack can act as a script interpreter (see [Script interpreter] (https://github.com/commercialhaskell/stack/wiki/Script-interpreter) and [Reddit discussion](http://www.reddit.com/r/haskell/comments/3bd66h/stack_runghc_turtle_as_haskell_script_solution/)) * Add the __`--file-watch`__ flag to auto-rebuild on file changes [#113](https://github.com/commercialhaskell/stack/issues/113) * Rename `stack docker exec` to `stack exec --plain` * Add the `--skip-msys` flag [#377](https://github.com/commercialhaskell/stack/issues/377) * `--keep-going`, turned on by default for tests and benchmarks [#478](https://github.com/commercialhaskell/stack/issues/478) * `concurrent-tests: BOOL` [#492](https://github.com/commercialhaskell/stack/issues/492) * Use hashes to check file dirtiness [#502](https://github.com/commercialhaskell/stack/issues/502) * Install correct GHC build on systems with libgmp.so.3 [#465](https://github.com/commercialhaskell/stack/issues/465) * `stack upgrade` checks version before upgrading [#447](https://github.com/commercialhaskell/stack/issues/447) ## 0.1.1.0 -

The command provides a simple interface for simple tasks and flexibility for more complicated goals. See the introductory part of Stack's [user's guide](../tutorial/hello_world_example.md#the-stack-build-command) for an introduction to the command. ## Synonyms The synonym commands for `stack build` are: |Synonym command|Equivalent `stack build` command flag| |---------------|-------------------------------------| |`stack test` |`stack build --test` | |`stack bench` |`stack build --bench` | |`stack haddock`|`stack build --haddock` | |`stack install`|`stack build --copy-bins` | The advantage of the synonym commands is that they are convenient and short. The advantage of the flags is that they compose. See the examples below. ## Components Every Cabal package is made up of one or more components. It can have an optional public library component, one or more optional executable components, one or more optional test suite components, and one or more optional benchmark components. Stack allows you to identify a specific component to be built. For example, `stack build mypackage:test:mytests` will build (and run - see further below) the `mytests` component of the `mypackage` package. `mytests` must be a test suite component. By default, if a test suite component is targeted, the component is built and run. The running behaviour can be disabled with the `--no-run-tests` flag. Similarly, if a benchmark component is targeted, it is built and run unless the running behaviour is disabled with the `--no-run-benchmarks` flag. This ability to specify a component applies only to a project package. With dependencies, Stack will *always* build the library (if present) and all executables (if any), and ignore test suites and benchmarks. If you want more control over a package, you must add it to your `packages` setting in your project-level configuration file (`stack.yaml`, by default). ## Target syntax `stack build` takes a list of one or more optional *targets* to be built. The supported syntaxes for targets are as follows: * no targets specified * *package* * *package identifier* * project package *component* * *local directory* ### No targets specified Example: `stack build` `stack build` with no targets specified will build all project packages. ### Target: *package* Example: `stack build foobar` Stack will try to find the package in the following locations: * project packages, * extra-deps, * the snapshot, and * the package index (e.g. Hackage). If the package is found in the package index, then the latest version of that package from the index is implicitly added as an extra-dep. If the package is a project package, the library and executable components are selected to be built. If the `--test` and `--bench` flags are set, then all of the test suite and benchmark components, respectively, are selected to be built. If *package* is a GHC boot package (packages that come with GHC and are included in GHC's global package database), the behaviour can be complex: * If the boot package has not been 'replaced', then `stack build` will, effectively, do nothing. * If the boot package has been 'replaced' then `stack build` will specify the latest version of that package in the package index, which may differ from the version provided by the version of GHC specified by the snapshot. A boot package will be treated as 'replaced' if the package is included directly in the Stackage snapshot or it depends on a package included directly in the snapshot. !!! note Stackage snapshots do not include directly most boot packages but some snapshots may include directly some boot packages. In particular, some snapshots include directly `Win32` (which is a boot package on Windows) while others do not. For example, if `Cabal` (a boot package) is not a project package or an extra-dep, then `stack build Cabal` with Stackage snapshot LTS Haskell 20.25 will: * on Windows, try to build the latest version of `Cabal` in the package index (because that snapshot includes `Win32` directly, and `Cabal` depends on `Win32` and so is treated as 'replaced'); and * on non-Windows, effectively, do nothing (because `Cabal` is not 'replaced'). ### Target: *package identifier* Example: `stack build foobar-1.2.3` If the package name is that of a project package, then Stack fails with an error. If the package version is an extra-dep or in the snapshot, then Stack will use that version. If the package version is in the package index (e.g. Hackage) then Stack will use the latest revision of that version from the package index. Otherwise, Stack will fail with an error. ### Target: project package *component* Examples: * `stack build my-package:lib` * `stack build my-package:exe:my-executable` * `stack build my-package:test:my-test-suite` * `stack build my-package:bench:my-benchmark` * `stack build my-package:my-test-suite` * `stack build :my-test-suite` You can select individual components from inside a project package to be built. This can be done for more fine-grained control over which test suites to run, or to have a faster compilation cycle. There are multiple ways to refer to a specific component: * `:lib` or `::` (where the component type, ``, is one of `exe`, `test`, or `bench`) is the most explicit. The library component type (`lib`) does not have an associated component name, ``. * `:` allows you to leave out the component type, as that will often be unique for a given component name. * `:` is a useful shortcut, saying "find the component`` in all of the project packages". This will result in an error if more than one package has a component with the specified name. For further information about available targets, see the [`stack ide targets` command](ide_command.md). ### Target: *local directory* Examples: * `stack build foo/bar` * `stack build ./foo` * `stack build .` Stack will find all project packages that exist in the given directory hierarchy and then follow the same procedure as passing in package names as mentioned above. `stack build .` will target project packages in the current working directory or its subdirectories. !!! note If the directory name is parsed as one of the other target types, it will be treated as that. Explicitly starting the target with `./` can avoid that. For example, `stack build ./foo`. ## Controlling what gets built Stack will rebuild a targeted project package if it considers one or more of its files to be dirty. Stack will consider a package to be dirty if a file is added to the `extra-source-files` field of its Cabal file or the contents of an existing file listed in the `extra-source-files` field is changed. ??? note "GHC's recompilation checker and Template Haskell" GHC's recompilation checker (which is on by default) stops compilation early if GHC can determine that a module does not need to be recompiled. For modules that use Template Haskell, when the module is compiled, GHC can determine dependencies, or be told about dependent files, of the code inserted by the splice. (Instances of the `Quasi` class promise to provide `qAddDependentFile`; see package `template-haskell`.) However, GHC cannot be told of as yet *unknown* dependent files when a module using Template Haskell is compiled. For example, this can affect the `embedDir` function provided by package `file-embed`, when files are added to the directory in question after the module is compiled. The resolution is either to specify GHC's `-fforce-recomp` option (to turn off the recompilation checker for the package) or to do a clean build. Stack will automatically build the necessary dependencies. See the introductory part of Stack's [user's guide](../tutorial/building_your_project.md#adding-dependencies) for information about how these dependencies get specified. If a package description specifies a custom build type, it must also specify a custom setup. That should list the dependencies needed to compile `Setup.hs`. Stack further customises the setup, using the `Cabal` package. If that package is not listed, Stack will warn and add the GHC boot package as a dependency. In addition to specifying targets, you can also control what gets built, or retained, with the flags and options listed below. You can also affect what gets built by specifying Cabal (the library) options for the configure step of the Cabal build process (for further information, see the documentation for the [configure-options](../configure/yaml/non-project.md#configure-options) configuration option). ### `--[no-]allow-newer` flag [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Overrides: [`allow-newer`](../configure/yaml/non-project.md#allow-newer) non-project specific configuration option Pass the flag to enable or disable the ignoring of lower and upper version bounds in Cabal files. !!! info The name `allow-newer` was chosen to match a commonly-used Cabal option which ignored only upper version bounds. ### `--bench` flag Pass the flag to add benchmark components to the targets, if specific components are not identified. The `stack bench` synonym sets this flag. ### `--dependencies-only` flag Pass the flag to skip building the targets. The flag `--only-dependencies` has the same effect. ### `--[no-]dry-run` flag Default: Disabled Set the flag to build nothing and output information about the build plan. ### `--flag` option The option can be specified multiple times. It has two forms: * `--flag :[-]`; and * `--flag *:[-]`. `stack build --flag :[-]` sets (or unsets) the specified Cabal flag for the specified package. Stack will report an error if: * a package of that name is not known to Stack; or * a flag of that name is not a flag of that package. This overrides: * any Cabal flag specifications for the package in the snapshot; * any Cabal flag specifications for the package in Stack's project-level configuration file (`stack.yaml`); and * any use of `--flag *` (see below). `stack build --flag *:[-]` sets (or unsets) the specified Cabal flag for all packages (project packages and dependencies) for which the flag is defined. This overrides: * any Cabal flag specifications for the relevant packages in the snapshot; and * any Cabal flag specifications for the relevant packages in Stack's project-level configuration file (`stack.yaml`). !!! info `flag *:[-] inspects the Cabal file of each package in the snapshot. Consequently, its use will add a few seconds to the duration of a build. !!! note For a package included directly in the snapshot, if the Cabal flag specifications differ from the Cabal flag specifications (if any) in the snapshot, then the package will automatically be promoted to be an [extra-dep](../configure/yaml/project.md#extra-deps). !!! note In order to set a Cabal flag for a GHC boot package, the package must be specified as an [extra-dep](../configure/yaml/project.md#extra-deps). ### `--[no-]force-dirty` flag Default: Disabled Set the flag to force rebuild of packages even when it doesn't seem necessary based on file dirtiness. ### `--[no-]haddock` flag Default: Disabled Set the flag to build Haddock documentation. This may cause a lot of packages to get re-built, so that the documentation links work. The `stack haddock` synonym sets this flag. Stack applies Haddock's `--gen-contents` and `--gen-index` flags to generate a single HTML contents and index for multiple sets of Haddock documentation. !!! warning On Windows, the values for the `haddock-interfaces` and `haddock-html` keys in the `*.conf` files for boot packages provided with certain versions of GHC (in its `lib\package.conf.d` directory) can be corrupt and refer to non-existent files and directories. For example, in the case of GHC 9.0.1 to GHC 9.8.1 the references are to `${pkgroot}/../../docs/html/libraries/...` or `${pkgroot}/../../doc/html/libraries/...` instead of `${pkgroot}/../docs/html/libraries/...` or `${pkgroot}/../doc/html/libraries/...`. Until those values are corrected, Haddock documentation will be missing links to what those packages expose. ### `--haddock-arguments` option `stack haddock --haddock-arguments ` passes the specified arguments to the Haddock tool. Specified arguments are separated by spaces. Arguments can be unquoted (if they do not contain space or `"` characters) or quoted (`""`). Quoted arguments can include 'escaped' characters, escaped with an initial `\` character. !!! note Haddock's `--latex` flag is incompatible with the Haddock flags used by Stack to generate a single HTML contents and index. ### `--[no-]haddock-deps` flag Default: Enabled (if building Haddock documnentation) Unset the flag to disable building Haddock documentation for dependencies. ### `--[no-]haddock-for-hackage` flag :octicons-beaker-24: Experimental [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Default: Disabled Set the flag to build project packages with flags to generate Haddock documentation suitable for upload to Hackage. The form of the Haddock documentation generated for other packages is unaffected. For each project package, the generated Haddock documentation files are in directory `doc\html\-docs\`, relative to Stack's dist work directory (see [`stack path --dist-dir`](path_command.md)). Unless flags are set to exclude the building of project packages, for each targeted project package with generated documentation, an archive of the `-docs` directory and its contents is in Stack's dist work directory. (The flags that exclude project packages are [`--only-dependencies`](#-only-dependencies-flag), [`--dependencies-only`](#-dependencies-only-flag), or [`--only-snapshot`](#-only-snapshot-flag).) If the flag is set: * the [`--[no-]haddock-hyperlink-source`](#-no-haddock-hyperlink-source-flag) flag is ignored and `--haddock-hyperlink-source` is implied; * the [`--[no-]haddock-deps`](#-no-haddock-deps-flag) flag is ignored and the default value for the flag is implied; * the [`--[no-]haddock-internal`](#-no-haddock-internal-flag) flag is ignored and `--no-haddock-internal` is implied; * the [`--[no-]open`](#-no-open-flag) flag is ignored and `--no-open` is implied; and * the [`--[no-]force-dirty`](#-no-force-dirty-flag) flag is ignored and `--force-dirty` is implied. !!! info Stack does not distinguish the building of Haddock documentation for Hackage from the building of Haddock documentation generally, which is why the `--force-dirty` flag is implied. !!! note If set, Haddock will warn that `-source-*` options are ignored when `--hyperlinked-source` is enabled. That is due to a known bug in Cabal (the libiary). !!! note If set, Cabal (the library) will report that documentation has been created in `index.html` and `.txt` files. Those files do not exist. That false report is due to a known bug in Cabal (the library). ### `--[no-]haddock-hyperlink-source` flag Default: Enabled Unset the flag to disable building building hyperlinked source for Haddock. If the [`--haddock-for-hackage`](#-no-haddock-for-hackage-flag) flag is passed, this flag is ignored. ### `--[no-]haddock-benchmarks` flag Default: Disabled Set the flag to enable building Haddock documentation for benchmark components of packages. If the [`--haddock-for-hackage`](#-no-haddock-for-hackage-flag) flag is passed, this flag is ignored. !!! note This feature is not supported by versions of Cabal (the library) provided with GHC 9.2.8 and earlier. !!! warning Due to a bug in versions of Cabal (the library) provided with GHC 9.8.2 and earlier, if there is more than one executable (including test suites and benchmarks) in a project package or more than one project package with an executable, the Haddock documentation for the `Main` module of one executable will overwrite the Haddock documentation for others. ### `--[no-]haddock-executables` flag Default: Disabled Set the flag to enable building Haddock documentation for executable components of packages. If the [`--haddock-for-hackage`](#-no-haddock-for-hackage-flag) flag is passed, this flag is ignored. !!! note This feature is not supported by versions of Cabal (the library) provided with GHC 9.2.8 and earlier. !!! warning Due to a bug in versions of Cabal (the library) provided with GHC 9.8.2 and earlier, if there is more than one executable (including test suites and benchmarks) in a project package or more than one project package with an executable, the Haddock documentation for the `Main` module of one executable will overwrite the Haddock documentation for others. ### `--[no-]haddock-internal` flag Default: Disabled Set the flag to enable building Haddock documentation for internal modules. If the [`--haddock-for-hackage`](#-no-haddock-for-hackage-flag) flag is passed, this flag is ignored. ### `--[no-]haddock-tests` flag Default: Disabled Set the flag to enable building Haddock documentation for test suite components of packages. If the [`--haddock-for-hackage`](#-no-haddock-for-hackage-flag) flag is passed, this flag is ignored. !!! note This feature is not supported by versions of Cabal (the library) provided with GHC 9.2.8 and earlier. !!! warning Due to a bug in versions of Cabal (the library) provided with GHC 9.8.2 and earlier, if there is more than one executable (including test suites and benchmarks) in a project package or more than one project package with an executable, the Haddock documentation for the `Main` module of one executable will overwrite the Haddock documentation for others. ### `--[no-]keep-going` flag Default (`stack build`): Disabled Default (`stack test` or `stack bench`): Enabled Set the flag to continue building packages even after some build step fails. The packages which depend upon the failed build won't get built. ### `--[no-]keep-tmp-files` flag Default: Disabled Set the flag to keep intermediate files and build directories that would otherwise be considered temporary and deleted. It may be useful to inspect these, if a build fails. By default, they are not kept. ### `--only-configure` flag [:octicons-tag-24: 0.1.4.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.4.0) Pass the flag to perform only the configure step, not any builds. This is intended for tool usage. It may break when used on multiple packages at once. !!! note If there are downstream actions that require a package to be built then a full build will occur, even if the flag is passed. ### `--only-dependencies` flag Pass the flag to skip building the targets. The flag `--dependencies-only` has the same effect. ### `--only-locals` flag Pass the flag to build only packages in the local database. Fails if the build plan includes packages in the snapshot database. ### `--only-snapshot` flag Pass the flag to build only snapshot dependencies, which are cached and shared with other projects. ### `--[no-]reconfigure` flag Default: Disabled Set the flag to force reconfiguration even when it doesn't seem necessary based on file dirtiness. This is sometimes useful with custom `Setup.hs` files, in particular when they depend on external data files. ### `--skip` option `stack build --skip ` skips building the specified components of a project package. It allows you to skip test suites and benchmark without specifying other components (e.g. `stack test --skip long-test-suite` will run the tests without the `long-test-suite` test suite). Be aware that skipping executables won't work the first time the package is built due to an issue in [Cabal](https://github.com/commercialhaskell/stack/issues/3229). This option can be specified multiple times to skip multiple components. ### `--test` flag Pass the flag to add test suite components to the targets, if specific components are not identified. The `stack test` synonym sets this flag. ## Controlling when building occurs ### `--file-watch` flag Pass the flag to rebuild your project every time a file changes. By default it will take into account all files belonging to the targets you specify. See also the `--watch-all` flag. ### `--file-watch-poll` flag Like the `--file-watch` flag, but based on polling the file system instead of using events to determine if a file has changed. ### `--watch-all` flag [:octicons-tag-24: 2.5.1](https://github.com/commercialhaskell/stack/releases/tag/v2.5.1) Pass the flag to rebuild your project every time any local file changes (from project packages or from dependencies located locally). See also the `--file-watch` flag. ## Controlling what happens after building ### `--benchmark-arguments`, `--ba` option `stack build --bench --benchmark-arguments=` will pass the specified argument, or arguments, to each benchmark when it is run. Specified arguments are separated by spaces. Arguments can be unquoted (if they do not contain space or `"` characters) or quoted (`""`). Quoted arguments can include 'escaped' characters, escaped with an initial `\` character. Account may need to be taken of the shell's approach to the processing of command line arguments: === "Unix-like (Bash or Zsh)" For example, to pass `word` and `words with spaces` in Bash, or Zsh: `stack test --benchmark-arguments 'word "words with spaces"'` The content of single quotes is taken literally, but cannot contain a single quote. For example, to pass `'a single quoted string'`: In Bash, or Zsh (if `RC_QUOTES` option not set): `stack bench --benchmark-arguments \"\''a single quoted string'\'\"` Outside of single quotes, `\"` escapes a double quote and `\'` escapes a single quote. The content of single quotes is taken literally, but cannot contain a single quote. In Zsh (if `RC_QUOTES` option set): `stack bench --benchmark-arguments '"''a single quoted string''"'` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. === "Windows" For example, to pass `word` and `words with spaces` in PowerShell: `stack test --benchmark-arguments 'word "words with spaces"'` The content of single quotes is taken literally. For example, to pass `'a single quoted string'` in PowerShell: `stack bench --benchmark-arguments '"''a single quoted string''"'` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. !!! note "Runtime system (RTS) options" RTS options must be quoted to prevent the RTS extracting them as its own when the Stack executable is run. ### `--exec` option `stack build --exec ' []'` will run the specified command after a successful build. Specified arguments are separated by spaces. Arguments can be unquoted (if they do not contain space or `"` characters) or quoted (`""`). Quoted arguments can include 'escaped' characters, escaped with an initial `\` character. Account may need to be taken of the shell's approach to the processing of command line arguments: === "Unix-like (Bash or Zsh)" For example, to pass `word` and `words with spaces` in Bash, or Zsh: `stack build --exec ' word "words with spaces"'` The content of single quotes is taken literally, but cannot contain a single quote.

In Zsh (if `RC_QUOTES` option set): `stack build --exec ' "''a single quoted string''"'` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. === "Windows" For example, to pass `word` and `words with spaces` in PowerShell: `stack build --exec ' word "words with spaces"'` The content of single quotes is taken literally. For example, to pass `'a single quoted string'` in PowerShell: `stack build --exec ' "''a single quoted string''"'` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. ### `--[no-]rerun-tests` flag Default: Enabled Unset the flag to disable the automatic running of targeted test-suites that have already been successful. ### `--[no-]run-benchmarks` flag Default: Enabled Unset the flag to disable the automatic running of targeted benchmarks. ### `--[no-]run-tests` flag Default: Enabled Unset the flag to disable the automatic running of targeted test suites. ### `--test-arguments`, `--ta` option `stack build --test --test-arguments=` will pass the specified argument, or arguments, to each test when it is run. This option can be specified multiple times. Specified arguments are separated by spaces. Arguments can be unquoted (if they do not contain space or `"` characters) or quoted (`""`). Quoted arguments can include 'escaped' characters, escaped with an initial `\` character.

For example, to pass `'a single quoted string'` in PowerShell: `stack test --test-arguments '"''a single quoted string''"'` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. !!! note "Runtime system (RTS) options" RTS options must be quoted to prevent the RTS extracting them as its own when the Stack executable is run. ## Flags affecting GHC's behaviour ### `--[no-]executable-profiling` flag Default: Disabled Set the flag to enable executable profiling for TARGETs and all its dependencies. The flag affects the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--[no-]executable-stripping` flag Default: Enabled Unset the flag to disable executable stripping for TARGETs and all its dependencies. The flag may affect the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--fast` flag GHC has many flags that specify individual optimisations of the compiler. GHC also uses its `-O*` flags to specify convenient 'packages' of GHC optimisation flags. GHC's flags are evaluated from left to right and later flags can override the effect of earlier ones. If no GHC `-O*` type flag is specified, GHC takes that to mean "Please compile quickly; I'm not over-bothered about compiled-code quality." GHC's `-O0` flag reverts to the same settings as if no `-O*` flags had been specified. Pass Stack's `--fast` flag to add `-O0` to the flags and options passed to GHC. The effect of `--fast` can be overriden with Stack's [`--ghc-options`](#-ghc-options-option) command line options. !!! note With one exception, GHC's `-O` flag is always passed to GHC first (being Cabal's default behaviour). The exception is if Cabal's `--disable-optimization` flag or `--enable-optimization[=n]`, `-O[n]` options are used during the configure step of the Cabal build process; see Stack's [`configure-options`](../configure/yaml/non-project.md#configure-options) non-project specific configuration option. ### `--ghc-options` option GHC command line options can be specified for a package in its Cabal file (including one created from a `package.yaml` file). This option augments and, if applicable (see below), overrides any such GHC command line options and those specified in Stack's configuration files - see the [`ghc-options`](../configure/yaml/non-project.md#ghc-options) non-project specific configuration option. `stack build --ghc-options ` passes the specified command line options to GHC, depending on Stack's [`apply-ghc-options`](../configure/yaml/non-project.md#apply-ghc-options) non-project specific configuration option. This option can be specified multiple times. GHC's command line options are _order-dependent_ and evaluated from left to right. Later options can override the effect of earlier ones. Any GHC command line options for a package specified at Stack's command line are applied after those specified in Stack's configuration files. ### `--[no-]library-profiling` flag Default: Disabled Set the flag to enable library profiling for TARGETs and all its dependencies. The flag affects the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--[no-]library-stripping` flag Default: Enabled Unset the flag to disable library stripping for TARGETs and all its dependencies. The flag may affect the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--pedantic` flag Pass the flag to build your project with the GHC options `-Wall` and `-Werror`. `-Wall` turns on all warning options that indicate potentially suspicious code. `-Werror` makes any warning into a fatal error. ### `--profile` flag Pass the flag to enable profiling in libraries, executables, etc. for all expressions, and generate a profiling report in tests or benchmarks. The flag affects the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--[no-]split-objs` flag :octicons-beaker-24: Experimental Default: Disabled Set the flag to enable the GHC option `-split-objs`. This will reduce output size (at the cost of build time). !!! note The behaviour of this feature may be changed and improved. You will need to clean your project's Stack working directory before use. If you want to compile all dependencies with split-objs, you will need to delete the snapshot (and all snapshots that could reference that snapshot). !!! note GHC's `-split-objs` flag was deprecated in favour of `-split-sections` in GHC 8.2.1 and was not supported by GHC on any platform from GHC 8.10.1. ### `--no-strip` flag Pass the flag to disable DWARF debugging symbol stripping in libraries, executables, etc. for all expressions, producing larger executables but allowing the use of standard debuggers/profiling tools/other utilities that use debugging symbols. The flag affects the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ### `--trace` flag Pass the flag to enable profiling in libraries, executables, etc. for all expressions, and generate a backtrace on exception. The flag affects the location of the local project installation directory. See the [`stack path --local-install-root`](path_command.md) command. ## Flags affecting other tools' behaviour ### `--PROG-option` options [:octicons-tag-24: 2.11.1](https://github.com/commercialhaskell/stack/releases/tag/v2.11.1) `PROG` is a program recognised by Cabal (the library) and one of `alex`, `ar`, `c2hs`, `cpphs`, `gcc`, `greencard`, `happy`, `hsc2hs`, `hscolour`, `ld`, `pkg-config`, `strip` and `tar`. `stack build --PROG-option ` passes the specified command line argument to `PROG`, if it used by Cabal during the configuration step. This option can be specified multiple times. For example, if the program `happy` is used by Cabal during the configuration step, you could command `stack build --happy-option=--ghc` or `stack build --happy-option --ghc` to pass to `happy` its `--ghc` flag. By default, all and any `--PROG-option` options on Stack's command line are applied to all project packages (targets or otherwise). This behaviour can be changed. See the [`apply-prog-options`](../configure/yaml/non-project.md#apply-prog-options) configuration option. Stack can also be configured to pass Cabal's `--PROG-option`, `--PROG-options` or other options to Cabal during the configuration step. For further information, see the documentation for the [configure-options](../configure/yaml/non-project.md#configure-options) configuration option. ## Flags relating to build outputs ### `--[no]-cabal-verbose` flag Default: Disabled Set the flag to enable verbose output from Cabal (the library). This flag is an alternative to the `--cabal-verbosity` option. ### `--[no]-cabal-verbosity` option `stack build --cabal-verbosity ` sets the specified verbosity level for output from Cabal (the library). It accepts Cabal's numerical and extended syntax. This option is an alternative to setting the `--cabal-verbose` flag. ### `--[no-]copy-bins` flag [:octicons-tag-24: 0.1.3.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.3.0) Default: Disabled Set the flag to enable copying of built executable files (binaries) of targets to Stack's local binary directory (see `stack path --local-bin`). The `stack install` synonym sets this flag. ### `--[no-]copy-compiler-tool` flag [:octicons-tag-24: 1.6.1](https://github.com/commercialhaskell/stack/releases/tag/v1.6.1) Default: Disabled Set the flag to enable copying of built executable files (binaries) of targets to Stack's compiler tools binary directory (see `stack path --compiler-tools-bin`). ### `--coverage` flag Pass the flag to generate a code coverage report. For further information, see the [code coverage](hpc_command.md) documentation. ### `--ddump-dir` option GHC has a number of `ddump-*` flags and options to allow dumping out of intermediate structures produced by the compiler. They include the `-ddump-to-file` flag that causes the output from other flags to be dumped to a file or files. `stack build --ddump_dir ` causes Stack to copy `*.dump-*` files to subdirectories of the specified directory, which is relative to Stack's working directory for the project. For example: ~~~text stack build --ghc-options "-ddump-to-file -ddump-timings" --ddump-dir my-ddump-dir ~~~ ### `--[no-]interleaved-output` flag [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Default: Enabled Set the flag for interleaved output. With interleaved output, each line of output from each package being built (targets and dependencies) is sent to the console as it happens and output relating to different packages can be interleaved. Each line will be prefixed with the name of the relevant package. The spacing between the prefix and the output will be set based on the longest relevant package name, so that the start of the output itself aligns. For example (extract): ~~~text hpack > build mustache > configure hpack > Preprocessing library for hpack-0.35.0.. hpack > Building library for hpack-0.35.0.. mustache > Configuring mustache-2.4.1... hpack > [ 1 of 29] Compiling Data.Aeson.Config.Key hpack > [ 2 of 29] Compiling Data.Aeson.Config.KeyMap mustache > build hpack > [ 3 of 29] Compiling Data.Aeson.Config.Util mustache > Preprocessing library for mustache-2.4.1.. mustache > Building library for mustache-2.4.1.. hpack > [ 4 of 29] Compiling Hpack.Haskell hpack > [ 5 of 29] Compiling Hpack.Utf8 mustache > [1 of 8] Compiling Paths_mustache hpack > [ 6 of 29] Compiling Imports hpack > [ 7 of 29] Compiling Hpack.Util mustache > [2 of 8] Compiling Text.Mustache.Internal ~~~ Unset the flag for non-interleaved output. With non-interleaved output, the build output from GHC (as opposed to from Stack) in respect of dependencies is ignored. The behaviour then depends whether there is one target package or more than one. There can be one target if the project has a single package or if one package is targeted in a multi-package project (for example, using `stack build `). * **One target package:** The build output for the target package is sent to the standard error stream of the console as it happens. * **More than one target package:** The build output from GHC (as opposed to from Stack) for each target package is sent to a log file for that package, unless an error occurs that prevents that. If color in output is in use, there will be two files, one with extension `.log` without color codes and one with extension `.log-color` with color codes. At the end of the build, the location of the directory containing the log files is reported. To also output the contents of the log files to the standard error output stream of the console at the end of the build, use Stack's `dump-logs` option. For further information about that option, see the [`dump-logs](../configure/yaml/non-project.md#dump-logs) non-project specific configuration option documentation. The default `dump-logs` mode is to output the contents of any log files that include GHC warnings. ### `--[no]-open` flag Default: Disabled Set the flag to enable opening the local Haddock documentation in the browser. ## Other flags and options ### `--[no]-prefetch` flag Default: Disabled Set the flag to enable fetching packages necessary for the build immediately. This can be useful with `stack build --dry-run`. ### `--progress-bar` option [:octicons-tag-24: 2.13.1](https://github.com/commercialhaskell/stack/releases/tag/v2.13.1) Default: `capped` `stack build --progress-bar ` sets the format of the progress bar, where `` is one of `none` (no bar), `count-only` (only the package count is displayed), `capped` (the bar showing package builds in progress is capped to a length equal to the terminal width), and `full` (the bar is uncapped). On terminals where 'backspace' has no effect if the cursor is in the first column, bars longer than the terminal width will not be 'sticky' at the bottom of the screen. ### `--tests-allow-stdin` flag [:octicons-tag-24: 2.9.3](https://github.com/commercialhaskell/stack/releases/tag/v2.9.3) Default: Enabled Cabal defines a test suite interface ['exitcode-stdio-1.0'](https://hackage.haskell.org/package/Cabal-syntax-3.8.1.0/docs/Distribution-Types-TestSuiteInterface.html#v:TestSuiteExeV1.0) where the test suite takes the form of an executable and the executable takes nothing on the standard input stream (`stdin`). Pass this flag to override that specification and allow the executable to receive input on that stream. If you pass `--no-tests-allow-stdin` and the executable seeks input on the standard input stream, an exception will be thown. ## Examples All the following examples assume that: * if `stack build` is commanded outside of a project directory, there is no `stack.yaml` file in the current directory or ancestor directory and, consequently, the project-level configuration will be determined by a `stack.yaml` file in the `global-project` directory in the [Stack root](../topics/stack_root.md) (for further information, see the [configuration](../configure/yaml/index.md) documentation); and * if `stack build` is commanded in a project directory, there is a `stack.yaml` file in that directory. Examples: * In the project directory, `stack build --test --copy-bins` or, equivalently, `stack test --copy-bins` or `stack install --test`, will build libraries, executables, and test suites, run the test suites, and then copy the executables to Stack's local binary directory (see `stack path --local-bin`). This is an example of the flags composing. * The following example uses a clone of the `wai` [repository](https://github.com/yesodweb/wai/). The `wai` project comprises a number of packages, including `wai-extra` and `warp`. In the `wai` project directory, the command: ~~~text stack build --file-watch --test --copy-bins --haddock wai-extra :warp warp:doctest --exec 'echo Yay, it worked!' ~~~ will start Stack up in file watch mode, waiting for files in your project to change. When first starting, and each time a file changes, it will do all of the following. * Build the `wai-extra` package and its test suites * Build the `warp` executable * Build the `warp` package's `doctest` component (which is a test site) * Run all of the `wai-extra` package's test suite components and the `doctest` test suite component * If all of that succeeds: * Copy generated executables to Stack's local binary directory (see `stack path --local-bin`) * Run the command `echo Yay, it worked!` * The following example uses the `Adga` package and assumes that `Adga-2.6.3` is the latest version in the package index (e.g. Hackage) and is not a version in the snapshot specified by the `stack.yaml` in the `global-project` directory in the Stack root. Outside a project directory, `stack build Adga-2.6.3 --copy-bins` or, equivalently, `stack install Agda-2.6.3`, will attempt to build the libraries and executables of the identified version of the package in the package index (using the `stack.yaml` file in the `global-project` directory in the Stack root), and then copy the executables to Stack's local binary directory (see `stack path --local-bin`). If a different snapshot is required to build the identified version of the package, then that can be specified at the command line. For example, to use the most recent Stackage Nightly snapshot: ~~~text stack --snapshot nightly install Agda-2.6.3 ~~~ Alternatively, Stack can be used to unpack the package from the package index into a local project directory named after the package identifier (for further infomation, see the [`stack unpack` command](unpack_command.md) documentation) and, if the package does not provide its own Stack configuration file (`stack.yaml`, by default), to attempt to initialise that configuration (for further information, see the [`stack init` command](init_command.md) documentation). For example: ~~~text stack unpack Agda-2.6.3 cd Agda-2.6.3 # Change to the project directory stack init # Attempt to create a project stack.yaml file stack install # Equivalent to stack build --copy-bins ~~~ stack-3.7.1/doc/commands/clean_command.md0000644000000000000000000000103014651506553016471 0ustar0000000000000000
# The `stack clean` command Either ~~~text stack clean [PACKAGE] ~~~ or ~~~text stack clean --full ~~~ `stack clean` deletes build artefacts for one or more project packages specified as arguments.

# The `stack dot` command ~~~text stack dot [--[no-]external] [--[no-]include-base] [--depth DEPTH] [--prune PACKAGES] [TARGET] [--flag PACKAGE:[-]FLAG] [--test] [--bench] [--global-hints] ~~~ A package and its dependencies and the direct dependency relationships between them form a directed graph. [Graphviz](https://www.graphviz.org/) is open source software that visualises graphs. It provides the DOT language for defining graphs and the `dot` executable for drawing directed graphs. Graphviz is available to [download](https://www.graphviz.org/download/) for Linux, Windows, macOS and FreeBSD. `stack dot` produces output, to the standard output stream, in the DOT language to represent the relationships between your packages and their dependencies. By default: * external dependencies are excluded from the output. Pass the flag `--external` to include external dependencies; * the `base` package and its dependencies are included in the output. Pass the flag `--no-include-base` to exclude `base` and its dependencies; * there is no limit to the depth of the resolution of dependencies. Pass the `--depth ` option to limit the depth; * all relevant packages are included in the output. Pass the `--prune ` option to exclude the specified packages (including project packages), where `` is a list of package names separated by commas; * for all relevant project packages, relevant dependencies are included in the output. However, each project package for which dependencies are included can be specified as a target argument. The argument uses the same format as the [`stack build` command](build_command.md) but components of project packages are ignored. Non-project packages are also ignored; * Cabal flags are as specified by the package description files and the project-level configuration file (`stack.yaml`, by default). Pass the option `--flag :` or `--flag :-` to set or unset a Cabal flag. This option can be specified multiple times; * test components of project packages are excluded from the output. Pass the flag `--test` to include test components; * benchmark components of project packages are excluded from the output. Pass the flag `--bench` to include benchmark components; and * global packages for the specified version of GHC are those specified by the global package database of an installed GHC. Pass the flag `--global-hints` to use a hint file for global packages. If a hint file is used, GHC does not need to be installed. ## Examples The following examples are based on a version of the [`wreq` package](https://hackage.haskell.org/package/wreq). In each case, the output from `stack dot` is piped as an input into Graphviz's `dot` executable, and `dot` produces output in the form of a PNG file named `wreq.png`. * A simple example: ~~~text stack dot | dot -Tpng -o wreq.png ~~~ [![wreq](https://cloud.githubusercontent.com/assets/591567/8478591/ae10a418-20d2-11e5-8945-55246dcfac62.png)](https://cloud.githubusercontent.com/assets/591567/8478591/ae10a418-20d2-11e5-8945-55246dcfac62.png) * Include external dependencies: ~~~text stack dot --external | dot -Tpng -o wreq.png ~~~ [![wreq_ext](https://cloud.githubusercontent.com/assets/591567/8478621/d247247e-20d2-11e5-993d-79096e382abd.png)](https://cloud.githubusercontent.com/assets/591567/8478621/d247247e-20d2-11e5-993d-79096e382abd.png) * Include external dependencies, limit the depth and save the output from `stack dot` as an intermediate file (`wreq.dot`). ~~~text stack dot --external --depth 1 > wreq.dot dot -Tpng -o wreq.png wreq.dot ~~~ * Include external dependencies, exclude `base` and limit the depth: ~~~text stack dot --no-include-base --external --depth 1 | dot -Tpng -o wreq.png ~~~ [![wreq_depth](https://cloud.githubusercontent.com/assets/591567/8484310/45b399a0-20f7-11e5-8068-031c2b352961.png)](https://cloud.githubusercontent.com/assets/591567/8484310/45b399a0-20f7-11e5-8068-031c2b352961.png) * Include external dependencies and prune `base` and other packages: ~~~text stack dot --external --prune base,lens,wreq-examples,http-client,aeson,tls,http-client-tls,exceptions | dot -Tpng -o wreq.png ~~~ [![wreq_pruned](https://cloud.githubusercontent.com/assets/591567/8478768/adbad280-20d3-11e5-9992-914dc24fe569.png)](https://cloud.githubusercontent.com/assets/591567/8478768/adbad280-20d3-11e5-9992-914dc24fe569.png) * Include external dependencies, prune `base` and other packages, and use a different Graphviz executable to draw the graph: Graphviz's `twopi` executable draws graphs in a radial layout. ~~~text stack dot --external --prune base,lens,wreq-examples,http-client,aeson,tls,http-client-tls,exceptions | twopi -Groot=wreq -Goverlap=false -Tpng -o wreq.png ~~~ [![wreq_pruned](https://cloud.githubusercontent.com/assets/591567/8495538/9fae1184-216e-11e5-9931-99e6147f8aed.png)](https://cloud.githubusercontent.com/assets/591567/8495538/9fae1184-216e-11e5-9931-99e6147f8aed.png) stack-3.7.1/doc/commands/eval_command.md0000644000000000000000000000132014651506553016340 0ustar0000000000000000
# The `stack eval` command ~~~text stack eval CODE [--[no-]ghc-package-path] [--[no-]stack-exe] [--package PACKAGE] [--rts-options RTSFLAG] [--cwd DIR] ~~~ GHC has an [expression-evaluation mode](https://downloads.haskell.org/ghc/latest/docs/users_guide/using.html#eval-mode), set by passing the GHC option `-e `.

If an executable is not specified, the first argument after `--` is taken to be the executable. Otherwise, all arguments after `--` are taken to be command line arguments for the specified executable. By default: * the `GHC_PACKAGE_PATH` environment variable is set for the command's process. Pass the flag `--no-ghc-package-path` to not set the environment variable; * if the operating system provides a reliable way to determine it and where a result was available, the `STACK_EXE` environment variable is set to the path to the current Stack executable for the command's process. Pass the flag `--no-stack-exe` to not set the environment variable; and * the specified executable is executed in the current directory. Pass the option `--cwd ` to execute the executable in the specified directory. The option `--package ` has no effect for the `stack exec` command. For further information about its use, see the [`stack ghc` command](ghc_command.md) documentation or the [`stack runghc` command](runghc_command.md) documentation. Pass the option `--rts-option ` to specify a GHC RTS flag or option. The option can be specified multiple times. All specified GHC RTS flags and options are added to the arguments for the specified executable between arguments `+RTS` and `-RTS`. Specified GHC RTS flags and options are separated by spaces. Items can be unquoted (if they do not contain space or `"` characters) or quoted (`""`). Quoted items can include 'escaped' characters, escaped with an initial `\` character. Account may need to be taken of the shell's approach to the processing of command line arguments. For example, to pass `'a single quoted string'`: === "Unix-like (Bash or Zsh)" In Bash, or Zsh (if `RC_QUOTES` option not set): `stack exec -- \''a single quoted string'\'` Outside of single quotes, `\'` escapes a single quote. The content of single quotes is taken literally, but cannot contain a single quote. In Zsh (if `RC_QUOTES` option set): `stack exec -- '''a single quoted string'''` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. === "Windows" In PowerShell: `stack exec -- '''a single quoted string'''` The content of single quotes is taken literally. Within single quotes, `''` escapes a single quote. The command also accepts flags and options of the [`stack build`](build_command.md#flags-affecting-ghcs-behaviour) command that affect the location of the local project installation directory, such as `--profile` and `--no-strip`.

GHCi is GHC's interactive environment. The `stack ghci` or `stack repl` commands, which are equivalent, allow you to load components and files of your project into GHCi. The command accepts the same TARGET syntax as [`stack build`](build_command.md#target-syntax). By default: * Stack loads up GHCi with all the library and executable components of all the packages in the project. Pass the flag `--test` to include test suite components (unlike `stack build`, test suites will not be run). Pass the flag `--bench` to include benchmark components (unlike `stack build`, benchmarks will not be run). It is also possible to specify a module source code file. For example: ~~~text stack ghci src/MyFile.hs ~~~ Stack will identify which component the file is associated with, and use the options from that component. Pass the `--package` option to load GHCi with an additional package that is not a direct dependency of your components. This option can be specified multiple times. Pass the option `--flag :` or `--flag ` to set or unset a Cabal flag. This option can be specified multiple times. The same Cabal flag name can be set (or unset) for multiple packages with: ~~~text --flag *:[-] ~~~ !!! note In order to set a Cabal flag for a GHC boot package, the package must either be an extra-dep or the package version must be specified with the `--package` option. By default: * Stack uses the GHC specified in Stack's configuration. Pass the `--with-ghc` option with a file path to the executable to specify a different GHC executable; * Stack performs an inital build step. Pass the `--no-build` flag to skip the step. Pass the `--ghc-options` option to pass flags or options to GHC. Pass the `--profile`, `--no-strip`, `--trace` flags for the same behaviour as in the case of the `stack build` command. !!! info Not performing the initial build step speeds up the startup of GHCi. It only works if the dependencies of the loaded packages have already been built. * Stack runs GHCi via `ghc --interactive`. Pass the `--ghc-options` option to pass flags or options to GHC (during the initial build step) and to GHCi. Pass the `--pedantic` flag to pass the GHC options `-Wall` and `-Werror` to GHCi (only). Pass the `--ghci-options` option to pass flags or options to GHCi (only). * Stack configures GHCi to hide unnecessary packages, unless no packages are targeted and no additional packages are specified. Pass the `--package-hiding` flag to hide unnecessary packages or `--no-package-hiding` flag not to hide unnecessary packages. * Stack loads and imports all of the modules for each target. Pass the `--no-load` flag to skip the loading of modules. Pass the `--only-main` flag to skip the loading of modules other than the main module. Pass the `--load-local-deps` flag to include all local dependencies of targets. !!! info Not loading modules speeds up the startup of GHCi. Once in GHCi, you can use `:load myModule` to load a specific module in your project. !!! info The `--only-main` flag can be useful if: 1. You're loading the project in order to run it in GHCi (e.g. via `main`), and you intend to reload while developing. Without flag, you will need to quit and restart GHCi whenever a module gets deleted. With the flag, reloading should work fine in this case. 2. If many of your modules have exports named the same thing, then you'll need to refer to them using qualified names. To avoid this, use the `--only-main` flag to start with a blank slate and just import the modules you are interested in. * If there are multiple definitions for the `Main` module, Stack will ask you to select one from a list of options. Pass the `--main-is ` option to specify which `Main` module to load. Stack combines all of the GHC options of components. !!! note Combining GHC options should work out when packages share similar conventions. However, conflicts may arise, such as when one component defines default extensions which aren't assumed by another. For example, specifying `NoImplicitPrelude` in one component but not another is likely to cause failures. GHCi will be run with `-XNoImplicitPrelude`, but it is likely that modules in the other component assume that the `Prelude` is implicitly imported. `stack ghci` configures GHCi by using a GHCi script file. Such files are located in subdirectories of `/stack/ghci-script`, where `` refers to the [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html) for user-specific non-essential (cached) data. === "Unix-like" The default for `` is `$HOME/.cache`. === "Windows" On Windows, the default for `` is `$Env:LOCALAPPDATA`. === "Windows (Command Prompt)" On Windows, the default for `` is `%LOCALAPPDATA%`. ## Running plain GHCi `stack ghci` always runs GHCi configured to load code from packages in your project. In particular, this means it passes in flags like `-hide-all-packages` and `-package-id=` in order to configure which packages are visible to GHCi. For doing experiments which just involve packages installed in your databases, it may be useful to run GHCi plainly like: ~~~text stack exec ghci ~~~ This will run a plain GHCi in an environment which includes `GHC_PACKAGE_PATH`, and so will have access to your databases. !!! note Running `stack ghci` on a pristine copy of the code doesn't currently build libraries (issue [#2790](https://github.com/commercialhaskell/stack/issues/2790)) or internal libraries (issue [#4148](https://github.com/commercialhaskell/stack/issues/4148)). It is recommended to always use `stack build` before using `stack ghci`, until these two issues are closed. stack-3.7.1/doc/commands/haddock_command.md0000644000000000000000000000340514734007355017012 0ustar0000000000000000

# The `stack hoogle` command ~~~text stack hoogle [-- ARGUMENT(S) (e.g. 'stack hoogle -- server --local')] [--[no-]setup] [--rebuild] [--server] ~~~ Hoogle is a Haskell API search engine. `stack hoogle` runs Hoogle. Stack needs Hoogle version 5 or greater. Stack will use a Hoogle database (`database.hoo`) specific to the project's source map and the version of GHC, located in a subdirectory of subdirectory `hoogle` of Stack's work directory for the project. By default: * if a `hoogle` executable is found on the `PATH`, Stack will try to use it. Otherwise, Stack will try to identify an executable as a build target. If the Hoogle database does not exist, Stack will generate it with `hoogle generate --local`. `hoogle generate --local` queries `ghc-pkg` and generates links for all packages which have documentation and Hoogle input files (`*.txt`) generated. Pass the flag `--no-setup` to skip such setup; * the existing Hoogle database is used. Pass the flag `--rebuild` to trigger the generation of a new Hoogle database (generated as above); and * `hoogle` is passed the specified arguments (if any). The arguments are usually the subject of the search. Pass the flag `--server` to first pass `server --local --port 8080` before those arguments. `hoogle server --local --port 8080` starts a local Hoogle web server, using port 8080, that allows the following of `file://` links. stack-3.7.1/doc/commands/hpc_command.md0000644000000000000000000001540514651506553016174 0ustar0000000000000000
# The `stack hpc` commands ~~~text stack hpc COMMAND Available commands: report Generate unified HPC coverage report from tix files and project targets ~~~ Code coverage is a measure of the degree to which the source code of a program is executed when a test suite is run. [Haskell Program Coverage (HPC)](https://ku-fpg.github.io/software/hpc/) is a code coverage tool for Haskell that is provided with GHC. Code coverage is enabled by passing the flag `--coverage` to `stack build`. `stack hpc` provides commands specific to HPC. Command `stack hpc` for the available commands. The following refers to the local HPC root directory. Its location can be obtained by command: ~~~text stack path --local-hpc-root ~~~ ## The `stack hpc report` command ~~~text stack hpc report [TARGET_OR_TIX] [--all] [--destdir DIR] [--open] ~~~ The `stack hpc report` command generates a report for a selection of targets and `.tix` files. Pass the flag `--all` for a report that uses all stored results. Pass the flag `--open` to open the HTML report in your browser. ## The `extra-tix-files` directory During the execution of the build, you can place additional tix files in the `extra-tix-files` subdirectory in the local HPC root directory, in order for them to be included in the unified report. A couple caveats: 1. These tix files must be generated by executables that are built against the exact same library versions. Also note that, on subsequent builds with coverage, the local HPC root directory will be recursively deleted. It just stores the most recent coverage data. 2. These tix files will not be considered by `stack hpc report` unless listed explicitly by file name. ## Examples If we have three different packages with test suites, packages `A`, `B`, and `C`, the default unified report will have coverage from all three. If we want a unified report with just two, we can instead command: ~~~text stack hpc report A B ~~~ This will output to the standard output stream a summary report for the combined coverage from `A` and `B`'s test suites. It will also log the path to the HTML for the corresponding full report. This command also supports taking extra `.tix` files. If you've also built an executable, against exactly the same library versions of `A`, `B`, and `C`, then you could command the following: ~~~text stack exec -- an-exe stack hpc report A B C an-exe.tix ~~~ or, equivalently: ~~~text stack exec -- an-exe stack hpc report --all an-exe.tix ~~~ This report will consider all test results as well as the newly generated `an-exe.tix` file. ## Usage `stack test --coverage` is quite streamlined for the following use-case: 1. You have test suites which exercise your project packages. 2. These test suites link against your library, rather than building the library directly. Coverage information is only given for libraries, ignoring the modules which get compiled directly into your executable. A common case where this doesn't happen is when your test suite and library both have something like `hs-source-dirs: src/`. In this case, when building your test suite you may also be compiling your library, instead of just linking against it. When your project has these properties, you will get the following: 1. Summary coverage reports, sent to the standard output stream in the build output, and a log of the paths to the HTML for the corresponding full reports. 2. A summary unified report, sent to the standard output stream, and a log of the path to the HTML for the corresponding full report. These reports consider the coverage on all local libraries, based on all of the tests that were run. 3. An index of all generated HTML reports, in `index.html` in the local HPC root directory, and a log of the path to the HTML for that index. ## Implementation details Most users can get away with just understanding the above documentation. However, advanced users may want to understand exactly how `--coverage` works: 1. The GHC option `-fhpc` gets passed to all project packages. This tells GHC to output executables that track coverage information and output them to `.tix` files. `the-exe-name.tix` files will get written to the working directory of the executable. When switching on this flag, it will usually cause all project packages to be rebuilt (see issue [#1940](https://github.com/commercialhaskell/stack/issues/1940)). 2. Before the build runs with `--coverage`, the contents of the local HPC root directory gets deleted. This prevents old reports from getting mixed with new reports. If you want to preserve report information from multiple runs, copy the contents of this path to a new directory. 3. Before a test run, if a `test-name.tix` file exists in the package directory, it will be deleted. 4. After a test run, it will expect a `test-name.tix` file to exist. This file will then get loaded, modified, and outputted to `pkg-name/test-name/test-name.tix` in the local HPC root directory. The `.tix` file gets modified to remove coverage file that isn't associated with a library. So, this means that you won't get coverage information for the modules compiled in the `executable` or `test-suite` stanza of your Cabal file. This makes it possible to directly union multiple `*.tix` files from different executables (assuming they are using the exact same versions of the project packages). If there is enough popular demand, it may be possible in the future to give coverage information for modules that are compiled directly into the executable. See issue [#1359](https://github.com/commercialhaskell/stack/issues/1359). 5. Once we have a `.tix` file for a test, we also generate a summary report and a corresponding full report using HTML. The summary report is sent to the standard output stream. The index of the test-specific HTML report is available at `pkg-name/test-name/index.html` in the local HPC root directory. 6. After the build completes, if there are multiple output `*.tix` files, they get combined into a unified report. The index of this report will be available at `combined/all/index.html` in the local HPC root directory. 7. Finally, an index of the resulting coverage reports is generated. It links to the individual coverage reports (one for each test-suite), as well as the unified report. This index is available at `index.html` in the local HPC root directory. stack-3.7.1/doc/commands/ide_command.md0000644000000000000000000000350414651506553016160 0ustar0000000000000000
# The `stack ide` commands ~~~text stack ide COMMAND Available commands: packages List all available local loadable packages targets List all available Stack targets ~~~ The `stack ide` commands provide information that may be of use in an integrated development environment (IDE). See `stack ide` for the available commands. ## The `stack ide packages` command ~~~text stack ide packages [--stdout] [--cabal-files] ~~~ `stack ide packages` lists all available project packages that are loadable. By default: * its output is sent to the standard error stream. Pass the flag `--stdout` to change to the standard output stream; and * the output is the package name (without its version). Pass the flag `--cabal-files` to change to the full path to the package's Cabal file. ## The `stack ide targets` command ~~~text stack ide targets [--exes] [--tests] [--benchmarks] [--stdout] ~~~ `stack ide targets` lists all available Stack targets.

For example, for the Stack project itself, command: ~~~text cd stack stack ide targets ~~~ and the output from the second command is: ~~~text stack:lib stack:exe:stack stack:exe:stack-integration-test stack:test:stack-unit-test ~~~ or command: ~~~text stack ide targets --exes ~~~ and the output is: ~~~text stack:exe:stack stack:exe:stack-integration-test ~~~ stack-3.7.1/doc/commands/index.md0000644000000000000000000001625714734007300015025 0ustar0000000000000000--- title: Commands ---
# Commands (advanced) Some of Stack's features will not be needed regularly or by all users. This part of the guide and the part on [configuration](../configure/index.md) provide information about some of those features, organised as a reference guide. Some of the features are complex and separate pages are dedicated to them. ## stack command Stack is usually used with one of its commands (see further below). However: * `stack`, `stack --help` (or `-h`) lists Stack's commands, and flags and options common to those commands; * `stack --help` (or `-h`) — provides help on the particular Stack command, including flags and options specific to the command; and * `stack --version` identifies the version and Git hash of the Stack executable. !!! info "Runtime system (RTS) options" The Stack executable is built by GHC with the `-rtsopts=some` option. This means that the RTS extracts command-line arguments bracketed between `+RTS` and `-RTS` as its own when Stack is run. Only the following RTS options are available: * `-?` (e.g. `stack +RTS -?`) causes the RTS to output information about RTS options; and * `--info` (e.g. `stack +RTS --info`) causes the RTS to output information about the RTS. To avoid the RTS extracting such command-line arguments as its own when using Stack commands such as [`exec`](exec_command.md), [`test`](test_command.md) or [`bench`](bench_command.md), see the documentation for those commands. ## Stack commands (thematic) ### Setting up * [`setup`](setup_command.md) -

# The `stack init` command ~~~text stack init [DIR(S)] [--omit-packages] [--force] [--ignore-subdirs] ~~~ `stack init` initialises Stack's default project-level configuration file (`stack.yaml`) for an existing project, based on the Cabal file or `package.yaml` file for each of its packages. By default: * Stack searches for Cabal and `package.yaml` files in the current directory. Specify one or more directories as arguments to cause Stack to search them; * Stack also searches for Cabal and `package.yaml` files in subdirectories. Pass the flag `--ignore-subdirs` to ignore subdirectories; * Stack will not overwrite an existing `stack.yaml` file. Pass the flag `--force` to allow overwriting; and * Stack will not initialise if there are conflicting or incompatable user packages. Pass the flag `--omit-packages` to cause Stack to ignore such matters while initialising. If a snapshot is specified at the command line, `stack init` will try to use it. For further information, see the documentation for the [`--snapshot`](../configure/global_flags.md#-snapshot-option) and [`--resolver`](../configure/global_flags.md#-resolver-option) options. Otherwise, `stack init` will try to use the following Stackage snapshots in order of preference, using the first that is compatable: the most recent LTS Haskell, the most recent Stackage Nightly, and other LTS Haskell (most recent first). !!! note If Cabal (the tool) has been used in the directory, consider commanding `cabal clean` before applying `stack init`, in case Cabal has created any unintended Cabal files. stack-3.7.1/doc/commands/install_command.md0000644000000000000000000000340614734007355017064 0ustar0000000000000000

# The `stack list` command [:octicons-tag-24: 2.7.1](https://github.com/commercialhaskell/stack/releases/tag/v2.7.1) ~~~text stack list [PACKAGE] ~~~ `stack list ` will send to the standard output stream the latest version of the package from Hackage. If the package name cannot be found on Hackage, even after updating the package index, suggestions (not necessarily good ones) will be made about the intended package name. `stack --snapshot list ` will send to the standard output stream the version of the package included in the specified snapshot (either directly or indirectly, if a boot package of the compiler specified by the snapshot). If the package name cannot be found in the snapshot, the command will fail, identifying only the package(s) that did not appear in the snapshot. More than one package name can be specified. `stack --snapshot list` will send to the standard output stream a list of all the packages included directly in the specified snapshot (that is, excluding those included only indirectly as a boot package of the compiler specified by the snapshot). For example: ~~~text stack list base unix Win32 acme-missiles pantry base-4.21.0.0 unix-2.8.6.0 Win32-2.14.1.0 acme-missiles-0.3 pantry-0.10.1 stack list paltry Could not find package paltry, updating ...

By default: * with the `text` or `tree` subcommand (see below), the package name is followed by its version. Pass the `--license` flag to follow the package name with its licence. (Consistent with the Cabal package description format specification, only the American English spelling (license) is accepted.) * With the `text` or `tree` subcommand, the separator between the package name and what follows is a space character. Pass the `--separator` option to specify a different separator; * with the `text` command, all relevant package names are included. Pass the `--filter` option to specify an item to be filtered out from the results, if present. An item can be `$locals` (for all project packages) or a package name. It can be specified multiple times; !!! note The special value `$locals` will need to be enclosed with single quotes to distinguish it from a shell variable. * external dependencies are excluded from the output. Pass the flag `--external` to include external dependencies; * the `base` package and its dependencies are included in the output. Pass the flag `--no-include-base` to exclude `base` and its dependencies; * there is no limit to the depth of the resolution of dependencies. Pass the `--depth ` option to limit the depth; * all relevant packages are included in the output. Pass the `--prune ` option to exclude the specified packages (including project packages), where `` is a list of package names separated by commas; * for all relevant project packages, relevant dependencies are included in the output. However, each project package for which dependencies are included can be specified as a target argument. The argument uses the same format as the [`stack build` command](build_command.md) but components of project packages are ignored. Non-project packages are also ignored; !!! note If the first target is one of `cabal`, `json`, `text` and `tree`, then a subcommand must be specified. * test components of project packages are excluded from the output.

By default: * the global packages are those for the version of GHC specified by the snapshot according to a hints file. Pass the flag `--no-global-hints` to use the global package database of an installed GHC. !!! note For example, on Windows, `stack ls globals` will include a version of the `Win32` and `unix` packages but `stack ls globals --no-global-hints` will exclude the `unix` package - and vice versa on Unix-like operating systems. ## The `stack ls snapshots` command ~~~text stack ls snapshots [COMMAND] [-l|--lts] [-n|--nightly] Available commands: local View local snapshots remote View remote snapshots ~~~ `stack ls snapshots` will list all the local snapshots by default. You can also view the remote snapshots using `stack ls snapshots remote`. It also supports options for viewing only lts (`-l`) and nightly (`-n`) snapshots. ## The `stack ls stack-colors` command ~~~text stack ls stack-colors [--[no-]basic] [--[no-]sgr] [--[no-]example] ~~~ The British English spelling is also accepted (`stack ls stack-colours`). `stack ls stack-colors` will list all of Stack's output styles. A number of different formats for the output are available, see `stack ls stack-colors --help`. The default is a full report, with the equivalent SGR instructions and an example of the applied style. The latter can be disabled with flags `--no-sgr` and `--no-example`. The flag `--basic` specifies a more basic report, in the format that is accepted by Stack's command line option `--stack-colors` and the [`stack-colors`](../configure/yaml/non-project.md#stack-colors) non-project specific configuration option. ## The `stack ls tools` command ~~~text stack ls tools [--filter TOOL_NAME] ~~~ `stack ls tools` will list Stack's installed tools. On Unix-like operating systems, they will be one or more versions of GHC. On Windows, they will include MSYS2. For example, on Windows the command: ~~~text stack ls tools ~~~ yields output like: ~~~text ghc-9.4.1 ghc-9.2.4 ghc-9.0.2 msys2-20210604 ~~~ The `--filter ` option will filter the output by a tool name (e.g. 'ghc', 'ghc-git' or 'msys2'). The tool name is case sensitive. For example the command: ~~~text stack ls tools --filter ghc ~~~ yields output like: ~~~text ghc-9.4.1 ghc-9.2.4 ghc-9.0.2 ~~~ stack-3.7.1/doc/commands/new_command.md0000644000000000000000000001141214734007300016171 0ustar0000000000000000
# The `stack new` command ~~~text stack new PACKAGE_NAME [--bare] [--[no-]init] [TEMPLATE_NAME] [-p|--param KEY:VALUE] [DIR(S)] [--omit-packages] [--force] [--ignore-subdirs] ~~~ `stack new` creates a new project using a project template. By default: * the project is created in a new directory named after the package. Pass the `--bare` flag to create the project in the current directory; * the project is initialised for use with Stack. Pass the `--no-init` flag to skip such initialisation; and * the project template is the one specified by the [default-template](../configure/yaml/non-project.md#default-template) option. A package name acceptable to Cabal comprises an alphanumeric 'word'; or two or more such words, with the words separated by a hyphen/minus character (`-`). A word cannot be comprised only of the characters `0` to `9`. An alphanumeric character is one in one of the Unicode Letter categories (Lu (uppercase), Ll (lowercase), Lt (titlecase), Lm (modifier), or Lo (other)) or Number categories (Nd (decimal), Nl (letter), or No (other)). !!! note In the case of Hackage and acceptable package names, an alphanumeric character is limited to one of `A` to `Z`, `a` to `z`, and `0` to `9`. !!! note The name of a project is not constrained to be an acceptable package name. A single-package project can be renamed to differ from the name of its package. The `--param :` option specifies a key-value pair to populate a key in a template. The option can be specified multiple times. The arguments specifying directories and the `--ignore-subdirs`, `--force` and `--omit-packages` flags are as for the [`stack init` command](init_command.md). These arguments are ignored if the `--no-init` flag is passed. If a snapshot is specified at the command line and the project is initialised for use with Stack, `stack new` will try to use it. For further information, see the documentation for the [`--snapshot`](../configure/global_flags.md#-snapshot-option) and [`--resolver`](../configure/global_flags.md#-resolver-option) options. ## Project templates A project template file can be located in a repository named `stack-templates` on GitHub, GitLab or Bitbucket; at a URL; or on the local file system. Project template file names have the extension `.hsfiles`. The extension does not need to be specified with `stack new`. A project template file `my-template.hsfiles` in a repository `username/stack-templates` on GitHub, GitLab or Bitbucket can be specified with `stack new` as: ~~~test :username/my-template ~~~ where `` is one of `github` for [GitHub](https://github.com/), `gitlab` for [GitLab](https://gitlab.com), or `bitbucket` for [Bitbucket](https://bitbucket.com). The default service is GitHub, the default username is `commercialhaskell` and the default project template name is `new-template`. ## Examples Create a project for package `my-project` in new directory `my-project` with the default project template file and initialise it for use with Stack: ~~~text stack new my-project ~~~ Create a project for package `my-package` in the current directory with the default project template file and initialise it for use with Stack: ~~~text stack new my-package --bare ~~~ Create a project with the `rio` project template at the default repository and initialise it for use with Stack: ~~~text stack new my-project rio ~~~ Create a project with the `mysql` project template provided by the `yesodweb/stack-templates` repository on GitHub and initialise it for use with Stack: ~~~text stack new my-project yesodweb/mysql ~~~ Create a project with the `my-template` project template provided by the `username/stack-templates` repository on Bitbucket and initialise it for use with Stack: ~~~text stack new my-project bitbucket:username/my-template ~~~ Create a project with the `my-template.hsfiles` project template file at `https://example.com` and initialise it for use with Stack: ~~~text stack new my-project https://example.com/my-template ~~~ Create a project with the local project template file `/my-template.hsfiles` and initialise it for use with Stack: ~~~text stack new my-project /my-template ~~~ Create a project with the `simple` project template file at the default repository (which does not use Hpack and a `package.yaml` file) and do not initialise it for use with Stack (`stack init` could be used subsequently): ~~~text stack new my-project --no-init simple ~~~ stack-3.7.1/doc/commands/path_command.md0000644000000000000000000000636014651506553016356 0ustar0000000000000000

For example: `packageA:a-exe` < `packageA:b-exe` < `packageB:a-exe` < `packageB:b-exe` Everything after `--` on the command line is interpreted as a command line argument to be passed to what is run, other than a first argument recognised as the name of an executable component of a project package. By default: * the `GHC_PACKAGE_PATH` environment variable is set for the subprocess. Pass the `--no-ghc-package-path` flag to not set the variable; and * the `STACK_EXE` environment variable is set with the path to Stack. Pass the `--no-stack-exe` flag to not set the variable. The `--cwd` option can be used to set the working directory before the executable is run. The `--package` option (which can be specified multiple times) can be used to add a package name to build targets. The `--rts-options` option (which can be specified multiple times) can be used to pass a list of GHC's [runtime system (RTS) options](https://downloads.haskell.org/~ghc/latest/docs/users_guide/runtime_control.html#) to the executable when it is run. (The `+RTS` and `-RTS` must not be included.) stack-3.7.1/doc/commands/runghc_command.md0000644000000000000000000000215114651506553016702 0ustar0000000000000000

# The `stack script` command ~~~text stack script [--package PACKAGE] FILE [-- ARGUMENT(S) (e.g. stack script X.hs -- argument(s) to program).] [--compile | --optimize] [--[no-]use-root] [--ghc-options OPTIONS] [--extra-dep EXTRA-DEP] [--no-run] ~~~ The `stack script` command either runs a specified Haskell source file (using GHC's `runghc`) or, optionally, compiles such a file (using GHC) and, by default, runs it. ## Global configuration files Non-project level configuration options in global configuration files (`config.yaml`) are not ignored by the `stack script` command. !!! info Non-project level configuration options may be useful if [`allow-newer`](../configure/yaml/non-project.md#allow-newer) and/or [`allow-newer-deps`](../configure/yaml/non-project.md#allow-newer-deps) are required. ## Project-level configuration file The `stack script` command ignores any project-level configuration file (`stack.yaml`, by default), including in the `global-project` directory in the Stack root. !!! info The `stack script` command can be contrasted with the [`stack ghc`](ghc_command.md) and [`stack runghc`](runghc_command.md) commands, which do not ignore any project-level configuration file. ## GHC The `stack script` command behaves as if the [`--install-ghc`](../configure/global_flags.md#-no-install-ghc-flag) flag had been passed at the command line. ## Snapshot and extra-deps A snapshot must be specified on the command line, using the `--snapshot` option. For example: ~~~text stack script --snapshot lts-23.24 MyScript.hs ~~~ An immutable extra-dep can be added to the snapshot on the command line with the `--extra-dep` option (which can be specified multiple times). An extra-dep is specified using a valid YAML value. For further information, see the [package location](../topics/package_location.md) documentation. Examples are: ~~~text --extra-dep acme-missiles-0.3@rev:0 --extra-dep '{git: git@github.com:yesodweb/wai, commit: '2f8a8e1b771829f4a8a77c0111352ce45a14c30f', subdirs: [auto-update, wai]} --extra-dep acme-missiles-0.3.tar.gz ~~~ Relative paths to local archive files are assumed to be relative to the directory in which the script file is located. GHC boot packages that have been 'replaced' (see further below) can be specified as an `--extra-dep`. ## Required packages The names of required packages can be either deduced or specified. The `base` package associated with the version of GHC specified by the snapshot is always available. If no packages are specified, all the required packages that are in the snapshot or are a GHC boot package (packages that come with GHC and are included in GHC's global package database), will be deduced by reference to the `import` statements in the source file. In that regard, Stack assumes that: * a line that begins `import` is an `import` statement; * `import` may be followed by `qualified` on the same line; * consistent with GHC's [`PackageImports`](https://downloads.haskell.org/ghc/latest/docs/users_guide/exts/package_qualified_imports.html) language extension, that if `import` or `import qualified` is followed by `""` on the same line, that `` is the name of a required package; * otherwise, `import` or `import qualified` is followed by the module name on the same line. Stack will not deduce the names of hidden packages from module names or the names of blacklisted packages. !!! note The first time that Stack deduces package names from module names can take some time. Use the `--verbose` option to understand Stack's progress. !!! note The installed packages of modules exposed by public sub-libraries will not be deduced, because those installed packages are hidden. !!! info Certain packages are blacklisted because they expose one or more modules with names that are the same as modules exposed by more popular packages. The blacklisted packages are `Glob`, `HTF`, `async-dejafu`, `binary-ieee754`, `cipher-aes`, `cipher-blowfish`, `cipher-camellia`, `cipher-des`, `cipher-rc4`, `control-monad-free`, `courier`, `crypto-api`, `crypto-cipher-types`, `crypto-numbers`, `crypto-pubkey`, `crypto-random`, `cryptohash`, `cryptohash-conduit`, `cryptohash-md5`, `cryptohash-sha1`, `cryptohash-sha256`, `fay-base`, `gl`, `gtk3`, `hashmap`, `hledger-web`, `hxt-unicode`, `kawhi`, `language-c`, `log`, `monad-extras`, `monads-tf`, `nanospec`, `newtype-generics`, `objective`, `plot-gtk3`, `prompt`, `regex-compat-tdfa`, `regex-pcre-builtin`, `rerebase`, `svg-tree` and `zip`. Alternatively, each required package can be specified by name on the command line with the `--package` option (which can be specified multiple times). A single `--package` option can also refer to a list of package names, separated by a space or comma character. If the package is not in the snapshot, the most recent version in the package index (e.g. Hackage) will be obtained. In the case of a named public sub-library of a Cabal package, the required installed package is specified by the 'munged' package name. For example, for public sub-library `my-library` of Cabal package `my-package` the munged name of the installed package is `z-my-library-z-my-package`. If a required package is a GHC boot package, the behaviour can be complex. If the boot package has not been 'replaced', then it will be used in Stack's build plan. However, if the boot package has been 'replaced', the latest version of that package in the package index will be used in Stack's build plan, which may differ from the version provided by the version of GHC specified by the snapshot. A boot package will be treated as 'replaced' if the package is included directly in the Stackage snapshot or it depends on a package included directly in the snapshot. Stackage snapshots do not include directly most boot packages but some snapshots may include directly some boot packages. In particular, some snapshots include directly `Win32` (which is a boot package on Windows) while others do not. !!! info GHC has the concept of 'installed packages' (which differ from 'Cabal packages') in package databases. An installed package has a name. An installed package corresponding to the main (unnamed) library of a Cabal package has the same name as the Cabal package. An installed package corresponding to a sub-library of a Cabal package has a 'munged' name that reflects the name of the Cabal package and the name of the sub-library. An installed package corresponding to a sub-library also has a `package-name`, which is the name of the Cabal package. The `--package` option of `stack script` makes use of GHC's `-package-id` option to expose an installed package, rather than its `-package` option. The latter option treats `package-name` (if it exists) as if it were also the name of the installed package. That means, for a Cabal package with one or more sub-libraries, the GHC option `-package=` cannot distinguish between (a) the installed package `` corresponding to the main library of Cabal package `` and (b) an installed package corresponding to a sub-library of that Cabal package. The installed package that GHC picks to expose is indeterminate. This can cause GHC to pick the wrong installed package and to report that it cannot load a module because it is a member of a hidden package. ## Compilation The source file can be compiled by passing either the `--compile` flag (no optimization) or the `--optimize` flag (compilation with optimization). If the file is compiled, passing the `--no-run` flag will mean the compiled code is not run. By default, all the compilation outputs (including the executable) are written to the directory of the source file. Pass the `--use-root` flag to write such outputs to a script-specific location in the `scripts` directory of the Stack root. The location reflects the absolute path to the source file, but ignoring the drive. This can avoid clutter in the source file directory. ## GHC options Additional options can be passed to GHC using the `--ghc-options` option. ## Script arguments Everything after `--` on the command line is interpreted as a command line argument to be passed to what is run. ## Examples ### Example 1 A Haskell source file `MyScript.hs` at location `Users/jane/my-project` (where `` could be `/` on Unix-like operating systems or `C:/` or similar on Windows): ~~~haskell module Main (main) where import Data.List (intercalate) import System.Environment (getArgs) import Acme.Missiles (launchMissiles) main :: IO () main = do advices <- getArgs launchMissiles putStrLn $ intercalate "\n" advices ~~~ can be compiled and run, with arguments, with: ~~~text stack --snapshot lts-23.24 script --package acme-missiles --compile MyScript.hs -- "Don't panic!" "Duck and cover!" ~~~ `acme-missiles-0.3` (the most recent version in the package index) will be used. All the compilation outputs (like `Main.hi`, `Main.o`, and the executable `MyScript`) will be written to the `my-project` directory. If compiled and run with the additional flag `--use-root`, all the compilation outputs will be written to a directory named `MyScript.hs` at `Users/jane/my-project/` in the `scripts` directory of the Stack root. ### Example 2 As for Example 1, but `acme-missiles-0.2` is specified by adding it to the snapshot as an extra-dep. The `stack script` command is specified using Stack's [script interpreter](../topics/scripts.md). ~~~haskell {- stack script -- snapshot lts-23.24 -- extra-dep acme-missiles-0.2 -- package acme-missiles -} module Main (main) where import Data.List (intercalate) import System.Environment (getArgs) import Acme.Missiles (launchMissiles) main :: IO () main = do advices <- getArgs launchMissiles putStrLn $ intercalate "\n" advices ~~~ ~~~text stack MyScript.hs "Don't panic!" "Duck and cover!" ~~~ ### Example 3 Stackage snapshot LTS Haskell 20.25 includes GHC boot package `Win32` directly. On Windows only, GHC boot packages `Cabal`, `directory`, `process` and `time` all depend on `Win32` and, consequently, are all treated as 'replaced'. Consequently, for example, Stack will: * on Windows, try to construct a build plan based on the latest version of `Cabal` in the package index; and * on non-Windows, use the boot package in the build plan (because `Cabal` is not 'replaced'). Consider also the following script extract, based on snapshot Stackage LTS Haskell 20.25, where considerations on Windows differ from non-Windows. The `stack script` command is specified using Stack's [script interpreter](../topics/scripts.md). === "Windows" ~~~haskell {- stack script --snapshot lts-20.25 --extra-dep acme-missiles-0.3 --extra-dep directory-1.3.6.2 --extra-dep process-1.6.16.0 --extra-dep time-1.11.1.1 -} import Acme.Missiles -- from acme-missiles import Data.Time.Clock.System -- from time import System.Time.Extra -- from extra ... ~~~ `acme-missiles` is not in the snapshot and so needs to be specified as an extra-dep. Stack can deduce that the module imports imply that the required packages are `acme-missiles`, `time` and `extra` (which is in the snapshot). `extra` depends on `directory` and `process`. If `directory` and `process` are not specified as extra-deps, Stack will complain that they have been 'pruned'. `directory-1.3.6.2` depends on `time < 1.12`. If `time` is not specified as an extra-dep, Stack will try to construct a build plan based on the latest version in the package index (which will fail, as the latest version is `>= 1.12`) === "Unix-like" ~~~haskell {- stack script --snapshot lts-20.25 --extra-dep acme-missiles-0.3 -} import Acme.Missiles -- from acme-missiles import Data.Time.Clock.System -- from time import System.Time.Extra -- from extra ... ~~~ `acme-missiles` is not in the snapshot and so needs to be specified as an extra-dep. Stack can deduce that the module imports imply that the required packages are `acme-missiles`, `time` and `extra` (which is in the snapshot). All the other dependencies required are either GHC boot packages (which have not been 'replaced') or in the snapshot. ### Example 4 A Haskell source file `MyScript.hs`, as follows: ~~~haskell {- stack script --snapshot lts-23.24 -} {-# LANGUAGE OverloadedStrings #-} {-# LANGUAGE PackageImports #-} module Main (main) where import "text" Data.Text (Text (..), unpack) main :: IO () main = putStrLn $ unpack "This is text." ~~~ As module `Data.Text` is exposed by a number of packages that are included, directly or indirectly, in the specified snapshot (`incipit-base`, `incipit-core`, `relude` and `text`), `PackageImports` and `"text"` are required to specify which module is being imported. ### Example 5 Stackage snapshot LTS Haskell 23.18 specifies Cabal package `vector-0.13.2.0` which includes public sub-library `benchmarks-O2`. The sub-library exposes module `Bench.Vector.TestData.ParenTree` which exports `parenTree`. The following is a valid script: ~~~haskell {- stack script --snapshot lts-23.18 --package z-vector-z-benchmarks-O2 -} {-# LANGUAGE LambdaCase #-} import Bench.Vector.TestData.ParenTree ( parenTree ) import System.Environment ( getArgs ) main :: IO () main = getArgs >>= \case [] -> putStrLn "An initial argument is required." (arg:_) -> do let n = read arg if n >= 0 && even n then do putStrLn "A balanced binary tree structure" putStrLn $ "with " <> show n <> " parentheses positions:" print $ parenTree n else putStrLn "A positive even integer argument is required." ~~~ stack-3.7.1/doc/commands/sdist_command.md0000644000000000000000000000416614765330072016547 0ustar0000000000000000
# The `stack sdist` command ~~~text stack sdist [DIR] [--pvp-bounds PVP-BOUNDS] [--ignore-check] [--[no-]test-tarball] [--tar-dir ARG] ~~~ Hackage only accepts packages for uploading in a standard form, a compressed archive ('tarball') in the format produced by Cabal's `sdist` action. `stack sdist` generates a file for your package, in the format accepted by Hackage for uploads. The command will report the location of the generated file. By default: * a file is generated for each project package. In the alternative, one or more project package directories can be specified; * the command will check the package for common mistakes. Pass the flag `--ignore-check` to disable the checks; * Stack will not test the generated file by attempting to build it. Pass the flag `--test-tarball` to cause Stack to test the generated file; * the generated file will be created in the `dist` directory of the project package directory. For information about the directory's location, command [`stack path --dist-dir`](path_command.md). Pass the option ``--tar-dir ` to also copy the file to the specified directory; and * no PVP version bounds are added to the Cabal file of the package. Pass the option `--pvp-bounds ` to determine whether and, if so, how bounds should be added. The available modes for basic use are: `none`, `lower`, `upper`, and `both`. The available modes for use with Cabal file revisions are `lower-revision`, `upper-revision` and `both-revision`. For futher information, see the [`pvp-bounds`](../configure/yaml/non-project.md#pvp-bounds) non-project specific configuration option documentation. !!! note Stack checks a package for common mistakes using checks provided by Cabal (the library). The version of Cabal used by Stack to check may be older than the version used by Stack to build. stack-3.7.1/doc/commands/setup_command.md0000644000000000000000000001306315023557531016554 0ustar0000000000000000
# The `stack setup` command ~~~text stack setup [GHC_VERSION] [--[no-]reinstall] [--ghc-bindist URL] [--ghcjs-boot-options GHCJS_BOOT] [--[no-]ghcjs-boot-clean] ~~~ `stack setup` attempts to install a version of GHC and, on Windows, MSYS2. By default: * the version of GHC is the one required by the project. Specify the version of GHC as an argument to attempt to install a different version of GHC. For example `stack setup 9.8.4` will attempt to install GHC 9.8.4; and * an attempt to install is made only if the version of GHC is not already available to Stack. Pass the flag `--reinstall` (disabled by default) to attempt to install the version of GHC regardless of whether it is already available to Stack. Pass the option `--ghc-bindist ` to specify the URL of the GHC to be downloaded and installed. This option requires the use of the `--ghc-variant` option specifying a custom GHC variant. For further information about the `--ghc-variant` option, see the [`ghc-variant`](../configure/yaml/non-project.md#ghc-variant) non-project specific configuration option documentation. If Stack is configured not to install GHC (`install-ghc: false` or passing the `--no-install-ghc` flag) or not to install MSYS2 (`install-msys: false` or passing the `--no-install-msys` flag) then `stack setup` will warn that the flag and the command are inconsistent and take no action. === "Linux" A particular binary distribution of GHC will depend on certain libraries, which need to be available. There are many different Linux distributions and different versions of a particular Linux distribution. One Linux distribution/version may make available different libraries to another Linux distribution/version. In attempting to identify the particular binary distribution of GHC that is required on Linux, Stack will refer to the presence or absence of certain libraries or the versions of those libraries. For example, Stack 3.1.1 considers: * If `libc.musl-x86_64.so.1` is present. This file is provided by the [musl libc](https://musl.libc.org/). [:octicons-tag-24: 2.13.1](https://github.com/commercialhaskell/stack/releases/tag/v2.13.1) * The version of `libc6` (if musl libc is not applicable), the [GNU C Library](https://www.gnu.org/software/libc/) (glibc), that is present. The GNU C Library is designed to be backwards compatible. [:octicons-tag-24: 2.11.1](https://github.com/commercialhaskell/stack/releases/tag/v2.11.1) * If `libgmp.so.3` or `libgmp.so.10` is present. These files are provided by different versions of the [GNU Multiple Precision Arithmetic Library](https://gmplib.org/). * If `libncursesw.so.6` is present. This file is provided by a shared library for terminal handling with wide character support. * If `libtinfo.so.5` or `libtinfo.so.6` is present. These files are provided by different versions of a shared low-level terminfo library for terminal handling. Stack 3.1.1 uses `ghc-build`: * `musl` to indicate `libc.musl-x86_64.so.1` is present and Stack should use the GHC binary distribution for Alpine Linux. * `tinfo6` to indicate `libgmp.so.10` and `libtinfo.so.6` are present and `libc6` is compatible with `libc6` 2.32. * `tinfo6-libc6-pre232` to indicate `libgmp.so.10` and `libtinfo.so.6` are present and `libc6` is not compatible with `libc6` 2.32. * `ncurses6` to indicate `libgmp.so.10` and `libncursesw.so.6` are present * `gmp4` to indicate `libgmp.so.3` is present By default, Stack associates: * the `tinfo6` build with the 'Fedora 33' binary distribution of GHC 9.4.1 to 9.4.3 and 9.6.1 and later. Those binary distributions require versions of `libc6` that are compatible with `libc6` 2.32; * the `tinfo6-libc6-pre232` build with the 'Debian 10' binary distribution of GHC 9.4.1 to 9.4.3 and the 'Rocky 8' binary distribution of GHC 9.6.1 and later. Those binary distributions require versions of `libc6` that are compatible with `libc6` 2.28; and * the `tinfo6` and `tinfo6-libc6-pre232` builds with the 'Fedora 27' binary distribution of GHC 9.4.4 to 9.4.8. Those binary distributions require versions of `libc6` that are compatible with `libc6` 2.26. === "Windows" Since Windows 10 version 1607, Windows has been 'long file paths' capable but that capability is not enabled by default. Consequently, Stack does not assume that it is being used on a system that is 'long file paths' enabled. Stack uses the 7-Zip tool to decompress, and extract tools from, downloaded archive files. Aiming to avoid long file paths, Stack does so in a temporary directory (named `stack-tmp-`) on the drive of the final destination (either in the system temporary directory, where applicable, or the root of the drive). Consequently, Stack needs permission to create a directory in that location. A Windows user account will usually have permission to create a directory in the system temporary directory. A Windows user account of type Administrator will have permission to create a directory in the root of the system drive (`C:\`, by convention) but a Standard user account may well not have permission. stack-3.7.1/doc/commands/templates_command.md0000644000000000000000000000322714651506553017417 0ustar0000000000000000
# The `stack templates` command ~~~text stack templates ~~~ `stack templates` provides information to the standard output stream about project templates used with the [`stack new` command](new_command.md). Project templates are specified in `.hsfiles` files. The format of those files is documented at the [`commercialhaskell/stack-templates`](https://github.com/commercialhaskell/stack-templates#project-template-format) repository on GitHub. Any GitHub, GitLab or Bitbucket repository named `stack-templates` can provide project template files. For example, a template file `username/stack-templates/my-template.hsfiles` on GitHub can be identified as `username/my-template` when using `stack new`. The relevant service can be specified by a prefix: `github:` for [GitHub](https://github.com/) (the default service), `gitlab:` for [GitLab](https://gitlab.com), or `bitbucket:` for [Bitbucket](https://bitbucket.com). [`commercialhaskell/stack-templates`](https://github.com/commercialhaskell/stack-templates#project-template-format) on GitHub is the default repository for project templates. Its username (`commercialhaskell`) does not need to be specified when using `stack new`. The project template that `stack new` uses by default is named `new-template` and provided at the default repository. The default repository provides 24 other project templates. Its Wiki provides a description of some of those templates and information about the location of other templates. stack-3.7.1/doc/commands/test_command.md0000644000000000000000000000330714734007355016375 0ustar0000000000000000

In the case of packages from the package index, a target can be a package name only. In that case, by default: * if Stack's `--snapshot` option is not specified, the download is for the most recent version of the package in the package index.

In particular, some snapshots include directly `Win32` (which is a boot package on Windows) while others do not. Otherwise, a target should specify a package name and version (for example, `acme-missiles-0.3`). In the case of package versions from the package index, optionally, a revision in the package index can be specified by appending `@rev:` or `@sha256:` (for example, `acme-missiles-0.3@rev:0`). By default: * the download is from the package index. Pass the flag `--candidate` to specify package candidates; and !!! note Stack assumes that a package candidate archive is a `.tar.gz` file named after the package version and located at endpoint `package\\candidate\`. This is true of Hackage. * the target is unpacked into a subdirectory of the current directory. Pass the option `--to ` to specify an alternative destination directory to the current directory. The destination directory can be an absolute one or relative to the current directory. stack-3.7.1/doc/commands/update_command.md0000644000000000000000000000064014651506553016677 0ustar0000000000000000
# The `stack update` command ~~~text stack update ~~~ Generally, Stack automatically updates the package index when necessary. `stack update` will download the most recent set of packages from your package indices (e.g. Hackage). stack-3.7.1/doc/commands/upgrade_command.md0000644000000000000000000001103614734007355017043 0ustar0000000000000000
# The `stack upgrade` command Either: ~~~text stack upgrade [--binary-only] [--binary-platform ARG] [--force-download] [--[no-]only-local-bin] [--binary-version ARG] [--github-org ARG] [--github-repo ARG] ~~~ or: ~~~text stack upgrade [--source-only] [--git] [--git-repo ARG] [--git-branch ARG] ~~~ `stack upgrade` will get a new version of Stack. It can also get a version before the current version (downgrade). !!! warning If you use GHCup to install Stack, use only GHCup to upgrade Stack. By default: * the new version will be from an existing binary distribution. Pass the `--source-only` flag to specify compiling from source code. The `--binary-only` and `--source-only` flags are alternatives; * the new version will not overwrite the existing version unless it is newer. Pass the `--force-download` flag to force a download; * when an existing binary distribution is applicable, it will be put in Stack's local binary directory (see `stack path --local-bin`) and named `stack` (replacing any existing executable named `stack` there); * if the current running Stack executable is '`stack`' (that is, it was invoked as `stack` or, on Windows, `stack.exe` - this is case insensitive - and the Stack executable file is named `stack` or, on Windows, `stack.exe` - this is case sensitive), an existing binary distribution will replace it. If the executable is located outside of Stack's local binary directory, pass the `--only-local-bin` flag to skip that step; * if the current running Stack executable is not '`stack`' (as described above), an existing binary distribution will only be put in Stack's local binary directory and named `stack`. Pass the `--no-only-local-bin` flag to replace also the current running executable; * the new version will be the latest available. Pass the `--binary-version ` option to specify the version (this implies `--force-download`); * the binary distribution will be sought from the GitHub organisation/user `commercialhaskell`. Pass the `--github-org ` option to specify a different GitHub user; * the binary distribution will be sought from the GitHub repository `stack`. Pass the `--github-repo ` option to specify a different repository; and * the binary distribution will be sought for the current platform. Pass the `--binary-platform ` option to specify a different platform (`--`). When compiling from source code, by default: * Stack will obtain the source code for the most recent version in the package index (eg Hackage). Pass the flag `--git` to specify the most recent version from the `master` branch of Stack's repository (pass the option `--git-branch ` to specify a different branch and the option `--git-repo ` to specify a different repository). !!! note An earlier version of Stack could be inconsistent with some of the current contents of the Stack root. For further information about the contents of the Stack root and configuring its location, see the documentation about the [Stack root](../topics/stack_root.md). ## Examples * `stack upgrade` seeks an upgrade to the latest version of Stack available as a binary distribution for the platform, if newer. * `stack upgrade --force-download` seeks an upgrade to the latest version of Stack available as a binary distribution for the platform, even if not newer. * If the Stack executable is invoked as `my-stack`, `my-stack upgrade` seeks only to put the latest version of Stack available as a binary distribution for the platform, if newer, in Stack's local binary directory and name it `stack`. `my-stack upgrade --no-only-local-bin` seeks also to upgrade `my-stack` to the latest version of Stack available. * `stack upgrade --binary-version 2.15.1` seeks an upgrade to Stack 2.15.1 if available as a binary distribution for the platform, even if not newer. * `stack upgrade --source-only` seeks an upgrade by building Stack with Stack from the latest version of the source code in the package index (i.e. Hackage). * `stack upgrade --source-only --git` seeks an upgrade by building Stack with Stack from the latest version of the source code in the `master` branch of Stack's repository. stack-3.7.1/doc/commands/upload_command.md0000644000000000000000000001175214765330072016704 0ustar0000000000000000
# The `stack upload` command ~~~text stack upload [ITEM] [-d|--documentation] [--pvp-bounds PVP-BOUNDS] [--ignore-check] [--[no-]test-tarball] [--tar-dir ARG] [--candidate] [--[no-]save-hackage-creds] [--setup-info-yaml URL] [--snapshot-location-base URL] ~~~ By default: * the command uploads one or more packages. Pass the flag `--documentation` (`-d` for short) to upload documentation for one or more packages; * the upload is a package to be published or documentation for a published package. Pass the flag `--candidate` to upload a [package candidate](http://hackage.haskell.org/upload#candidates) or documentation for a package candidate; and * the command prompts to save the user's Hackage username and password in a local file. Pass the flag `--no-save-hackage-creds` to avoid the prompt. At least one `ITEM` must be specified. For example, if the current working directory is a package directory: ~~~text stack upload . ~~~ ## Upload one or more packages Hackage accepts packages for uploading in a standard form, a compressed archive ('tarball') in the format produced by Cabal's `sdist` action. If `ITEM` is a relative path to an sdist tarball, `stack upload` uploads the package to Hackage. If `ITEM` is a relative path to a package directory, `stack upload` generates a file for your package, in the format accepted by Hackage for uploads, and uploads the package to Hackage. By default: * the command will check each package for common mistakes. For further information, see the [`stack sdist` command](sdist_command.md) documentation. Pass the flag `--ignore-check` to disable such checks; and * Stack will not test the resulting package archive. Pass the flag `--test-tarball` to cause Stack to test each resulting package archive, by attempting to build it. The `--pvp-bounds ` option determines whether and, if so, how PVP version bounds should be added to the Cabal file of the package. The available modes for basic use are: `none`, `lower`, `upper`, and `both`. The available modes for use with Cabal file revisions are `lower-revision`, `upper-revision` and `both-revision`. For futher information, see the [`pvp-bounds`](../configure/yaml/non-project.md#pvp-bounds) non-project specific configuration option documentation. The `--tar-dir ` option determines whether the package archive should be copied to the specified directory. ## Upload documentation for a package :octicons-beaker-24: Experimental [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Hackage accepts documentation for a package for uploading in a standard form and in a compressed archive ('tarball') in the `.tar.gz` format. For further information about how to create such an archive file, see the documentation for the [`stack haddock --haddock-for-hackage`](build_command.md#-no-haddock-for-hackage-flag) command. If `ITEM` is a relative path to a package directory, `stack upload --documentation` uploads an existing archive file of documentation for the specified package to Hackage. If the `--documentation` flag is passed then flags specific to package upload are ignored. ## The `HACKAGE_USERNAME` and `HACKAGE_PASSWORD` environment variables [:octicons-tag-24: 2.3.1](https://github.com/commercialhaskell/stack/releases/tag/v2.3.1) `stack upload` will request a Hackage username and password to authenticate. This can be avoided by setting the `HACKAGE_USERNAME` and `HACKAGE_PASSWORD` environment variables. For example: === "Unix-like" ~~~text export $HACKAGE_USERNAME="" export $HACKAGE_PASSWORD="" stack upload . ~~~ === "Windows" ~~~text $Env:HACKAGE_USERNAME='' $Env:HACKAGE_PASSWORD='' stack upload . ~~~ === "Windows (Command Prompt)" ~~~text set HACKAGE_USERNAME= set HACKAGE_PASSWORD= stack upload . ~~~ ## The `HACKAGE_KEY` environment variable [:octicons-tag-24: 2.7.5](https://github.com/commercialhaskell/stack/releases/tag/v2.7.5) Hackage allows its members to register an API authentification token and to authenticate using the token. A Hackage API authentification token can be used with `stack upload` instead of username and password, by setting the `HACKAGE_KEY` environment variable. For example: === "Unix-like" ~~~text HACKAGE_KEY= stack upload . ~~~ === "Windows" ~~~text $Env:HACKAGE_KEY= stack upload . ~~~ === "Windows (Command Prompt)" ~~~text set HACKAGE_KEY= stack upload . ~~~ stack-3.7.1/doc/community/index.md0000644000000000000000000000454114734007300015241 0ustar0000000000000000--- title: Get involved ---
# Get involved ## Feedback and discussion * For general comments, feedback and support, please post to the [Haskell Community](https://discourse.haskell.org/about) forum. * For bugs, issues, or requests, please [open an issue](https://github.com/commercialhaskell/stack/issues/new). * When using Stack Overflow, please use the [haskell-stack](http://stackoverflow.com/questions/tagged/haskell-stack) tag. ## How to contribute to the maintenance or development of Stack A [guide](../CONTRIBUTING.md) is provided to help potential contributors to the Stack project. If you have already installed a version of Stack and the [Git application](https://git-scm.com/) the followings steps should get you started with building Stack from source with Stack: 1. Clone the `stack` repository from GitHub with the command: ~~~text git clone https://github.com/commercialhaskell/stack.git ~~~ 2. Change the current working directory to the cloned `stack` directory with the command: ~~~text cd stack ~~~ 3. Build the `stack` executable using a preexisting installation of Stack with the command: ~~~text stack build ~~~ 4. Once the `stack` executable has been built, check its version with the command: ~~~text stack exec -- stack --version ~~~ Make sure the version is the latest one. 5. In the GitHub repository's issue tracker, look for issues tagged with [newcomer friendly](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3a%22newcomer+friendly%22) and [awaiting pull request](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3A%22awaiting+pull+request%22) labels. If you need to check your changes quickly command: ~~~text stack repl ~~~ and then, at the REPL's prompt, command: ~~~text :main --stack-root= --stack-yaml= ~~~ This allows you to set a special Stack root (instead of the default Stack root) and to target your commands at a particular `stack.yaml` file instead of the one found in the current directory. stack-3.7.1/doc/configure/customisation_scripts.md0000644000000000000000000001012114651507314020536 0ustar0000000000000000
# Customisation scripts ## GHC installation customisation [:octicons-tag-24: 2.9.1](https://github.com/commercialhaskell/stack/releases/tag/v2.9.1) On Unix-like operating systems and Windows, Stack's installation procedure can be fully customised by placing a `sh` shell script (a 'hook') in the [Stack root](../topics/stack_root.md) directory at `hooks/ghc-install.sh`. On Unix-like operating systems, the script file must be made executable. The script is run by the `sh` application (which is provided by MSYS2 on Windows). The script **must** return an exit code of `0` and the standard output **must** be the absolute path to the GHC binary that was installed. Otherwise Stack will ignore the script and possibly fall back to its own installation procedure. When `system-ghc: true`, the script is not run. That is because the two mechanisms reflect distinct concepts, namely: * `system-ghc: true` causes Stack to search the PATH for a version of GHC; and * `hooks/ghc-install.sh` causes Stack to execute a script that is intended to send to standard output a path to a version of GHC. The path in question may or may not be in the PATH. The script may also do other things, including installation. When `install-ghc: false`, the script is still run. That allows you to ensure that only your script will install GHC and Stack won't default to its own installation logic, even when the script fails. The following environment variables are always available to the script: * `HOOK_GHC_TYPE = "bindist" | "git" | "ghcjs"` For "bindist", additional variables are: * `HOOK_GHC_VERSION = ` For "git", additional variables are: * `HOOK_GHC_COMMIT = ` * `HOOK_GHC_FLAVOR = ` For "ghcjs", additional variables are: * `HOOK_GHC_VERSION = ` * `HOOK_GHCJS_VERSION = ` An example script is: ~~~sh #!/bin/sh set -eu case $HOOK_GHC_TYPE in bindist) # install GHC here, not printing to stdout, e.g.: # command install $HOOK_GHC_VERSION >/dev/null ;; git) >&2 echo "Hook doesn't support installing from source" exit 1 ;; *) >&2 echo "Unsupported GHC installation type: $HOOK_GHC_TYPE" exit 2 ;; esac echo "location/to/ghc/executable" ~~~ If the following script is installed by GHCup, GHCup makes use of it, so that if Stack needs a version of GHC, GHCup takes over obtaining and installing that version: ~~~sh #!/bin/sh set -eu case $HOOK_GHC_TYPE in bindist) ghcdir=$(ghcup whereis --directory ghc "$HOOK_GHC_VERSION" || ghcup run --ghc "$HOOK_GHC_VERSION" --install) || exit 3 printf "%s/ghc" "${ghcdir}" ;; git) # TODO: should be somewhat possible >&2 echo "Hook doesn't support installing from source" exit 1 ;; *) >&2 echo "Unsupported GHC installation type: $HOOK_GHC_TYPE" exit 2 ;; esac ~~~ ## `--file-watch` post-processing [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) On Unix-like operating systems and Windows, Stack's `build --file-watch` post-processing can be fully customised by specifying an executable or a `sh` shell script (a 'hook') using the [`file-watch-hook`](yaml/non-project.md#file-watch-hook) non-project specific configuration option. On Unix-like operating systems, the script file must be made executable. A script is run by the `sh` application (which is provided by MSYS2 on Windows). The following environment variables are always available to the executable or script: * `HOOK_FW_RESULT` (Equal to `""` if the build did not fail. Equal to the result of `displayException e`, if exception `e` thown during the build.) An example script is: ~~~sh #!/bin/sh set -eu if [ -z "$HOOK_FW_RESULT" ]; then echo "Success! Waiting for next file change." else echo "Build failed with exception:" echo $HOOK_FW_RESULT fi ~~~ stack-3.7.1/doc/configure/environment_variables.md0000644000000000000000000001330214765330072020467 0ustar0000000000000000
# Stack's environment variables The environment variables listed in alphabetal order below can affect how Stack behaves. If using Stack's [Nix integration](../topics/nix_integration.md#pure-and-impure-nix-shells) and a *pure* Nix build environment (or *shell*), by default, these environment variables will not be forwarded from your user session to the Nix shell. However, the Nix shell can be configured to keep specific environment variables. ## `GH_TOKEN` or `GITHUB_TOKEN` [:octicons-tag-24: 2.11.1](https://github.com/commercialhaskell/stack/releases/tag/v2.11.1) Stack will use the value of the `GH_TOKEN` or, in the alternative, `GITHUB_TOKEN` environment variable (if not an empty string) as credentials to authenticate its requests of the GitHub REST API, using HTTP 'Basic' authentication. GitHub limits the rate of unauthenticated requests to its API, although most users of Stack will not experience that limit from the use of Stack alone. The limit for authenticated requests is significantly higher. For more information about authentication of requests of the GitHub REST API, see GitHub's REST API documentation. ## `HACKAGE_KEY` [:octicons-tag-24: 2.7.5](https://github.com/commercialhaskell/stack/releases/tag/v2.7.5) Related command: [`stack upload`](../commands/upload_command.md) Hackage allows its members to register an API authentification token and to authenticate using the token. A Hackage API authentification token can be used with `stack upload` instead of username and password, by setting the `HACKAGE_KEY` environment variable. For example: === "Unix-like" ~~~text HACKAGE_KEY= stack upload . ~~~ === "Windows" ~~~text $Env:HACKAGE_KEY= stack upload . ~~~ === "Windows (Command Prompt)" ~~~text set HACKAGE_KEY= stack upload . ~~~ ## `HACKAGE_USERNAME` and `HACKAGE_PASSWORD` [:octicons-tag-24: 2.3.1](https://github.com/commercialhaskell/stack/releases/tag/v2.3.1) Related command: [`stack upload`](../commands/upload_command.md) `stack upload` will request a Hackage username and password to authenticate. This can be avoided by setting the `HACKAGE_USERNAME` and `HACKAGE_PASSWORD` environment variables. For example: === "Unix-like" ~~~text export $HACKAGE_USERNAME="" export $HACKAGE_PASSWORD="" stack upload . ~~~ === "Windows" ~~~text $Env:HACKAGE_USERNAME='' $Env:HACKAGE_PASSWORD='' stack upload . ~~~ === "Windows (Command Prompt)" ~~~text set HACKAGE_USERNAME= set HACKAGE_PASSWORD= stack upload . ~~~ ## `NO_COLOR` Related command: all commands that can produce colored output using control character sequences. Stack follows the standard at http://no-color.org/. Stack checks for a `NO_COLOR` environment variable. When it is present and not an empty string (regardless of its value), Stack prevents the addition of control character sequences for color to its output. ## `STACK_CONFIG` Related command: all commands that make use of Stack's [global configuration](yaml/index.md) files (`config.yaml`). The environment variable `STACK_CONFIG` can be used to specify an absolute path to the user-specific global configuration file, overriding the default. ## `STACK_GLOBAL_CONFIG` Related command: all commands that make use of Stack's [global configuration](yaml/index.md) files (`config.yaml`). The environment variable `STACK_GLOBAL_CONFIG` can be used to specify an absolute path to the system-wide global configuration file, overriding the default. ## `STACK_ROOT` Related command: all commands that make use of Stack's [user-specific global configuration](yaml/index.md) file (`config.yaml`). Overridden by: Stack's global [`--stack-root`](global_flags.md#-stack-root-option) option. The environment variable `STACK_ROOT` can be used to specify the [Stack root](../topics/stack_root.md) directory. ## `STACK_WORK` Related command: all commands that make use of Stack's work directories. Overridden by: Stack's [`work-dir`](yaml/non-project.md#work-dir) non-project specific configuration option, or global [`--work-dir`](global_flags.md#-work-dir-option) option. The environment variable `STACK_WORK` can be used to specify the path of Stack's work directory, within a local project or package directory, and override Stack's default of `.stack-work`. The path must be a relative one, relative to the root directory of the project or package. The relative path cannot include a `..` (parent directory) component. ## `STACK_XDG` Related command: all commands that make use of Stack's [user-specific global configuration](yaml/index.md) file (`config.yaml`). Overridden by: the use of Stack's `STACK_ROOT` environment variable, or the use of Stack's global [`--stack-root`](global_flags.md#-stack-root-option) option. On Unix-like operating systems and Windows, Stack can be configured to follow the XDG Base Directory Specification if the environment variable `STACK_XDG` is set to any non-empty value. ## `STACK_YAML` Related command: all commands that make use of Stack's [project-level configuration](yaml/index.md). Overridden by: Stack's global [`--stack-yaml`](global_flags.md#-stack-yaml-option) option. The environment variable `STACK_YAML` can be used to specify Stack's project-level configuration file. stack-3.7.1/doc/configure/global_flags.md0000644000000000000000000003654214774240637016531 0ustar0000000000000000
# Stack's global flags and options Stack can also be configured by flags and options on the command line. Global flags and options apply to all of Stack's commands. In addition, all of Stack's commands accept the `--setup-info-yaml` and `--snapshot-location-base` options and the `--help` flag. ## `--allow-different-user` flag Restrictions: POSIX systems only Default: True, if inside Docker; false otherwise Enable/disable permitting users other than the owner of the [Stack root](../topics/stack_root.md) directory to use a Stack installation. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#allow-different-user). ## `--arch` option Pass the option `--arch ` to specify the relevant machine architecture. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#arch). ## `--bash-completion-index` option Visibility: Hidden See the [shell auto-completion](../topics/shell_autocompletion.md) documentation. ## `--bash-completion-script` option Visibility: Hidden See the [shell auto-completion](../topics/shell_autocompletion.md) documentation. ## `--bash-completion-index` option Visibility: Hidden See the [shell auto-completion](../topics/shell_autocompletion.md) documentation. ## `--color` or `-colour` options Pass the option `stack --color ` to specify when to use color in output. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#color). ## `--compiler` option Pass the option `--compiler ` to specify the compiler. For further information, see the [`compiler`](yaml/non-project.md#compiler) non-project specific configuration option documentation. ## `--custom-preprocessor-extensions` option Pass the option `--custom-preprocessor-extensions ` to specify an extension used for a custom preprocessor. For further information, see the documentation for the corresponding project specific configuration [option](yaml/project.md#custom-preprocessor-extensions). ## `--docker*` flags and options Stack supports automatically performing builds inside a Docker container. For further information see `stack --docker-help` or the [Docker integration](../topics/docker_integration.md) documentation. ## `--[no-]dump-logs` flag Default: Dump warning logs Enables/disables the dumping of the build output logs for project packages to the console. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#dump-logs). ## `--extra-include-dirs` option Pass the option `--extra-include-dirs ` to specify an extra directory to check for C header files. The option can be specified multiple times. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#extra-include-dirs). ## `--extra-lib-dirs` option Pass the option `--extra-lib-dirs ` to specify an extra directory to check for libraries. The option can be specified multiple times. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#extra-lib-dirs). ## `--fish-completion-script` option Visibility: Hidden See the [shell auto-completion](../topics/shell_autocompletion.md) documentation. ## `--ghc-build` option Pass the option `--ghc-build ` to specify the relevant specialised GHC build. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#ghc-build). ## `--ghc-variant` option Pass the option `--ghc-variant ` to specify the relevant GHC variant. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#ghc-variant). ## `--help` or `-h` flags Pass the `--help` (or `-h`) flag to cause Stack to list its commands and flags and options common to those commands. Alternatively, command ~~~text stack ~~~ for the same information. ## `--[no-]hpack-force` flag [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Default: Disabled By default, Hpack 0.20.0 or later will decline to overwrite a Cabal file that has been modified manually. Pass the flag `--hpack-force` to allow Hpack to overwrite such a Cabal file. ## `--hpack-numeric-version` flag Pass the flag `--hpack-numeric-version` to cause Stack to report the numeric version of its built-in Hpack library to the standard output stream (e.g. `0.35.0`) and quit. ## `--[no-]install-ghc` flag Default: Enabled Enables/disables the download and installation of GHC when necessary. On Windows, `--no-install-ghc` also disables the download and installation of the Stack-supplied MSYS2 when necessary. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#install-ghc). ## `--[no-]install-msys` flag [:octicons-tag-24: 3.5.1](https://github.com/commercialhaskell/stack/releases/tag/v3.5.1) Restrictions: Windows systems only Default: Same as the [`install-ghc`](yaml/non-project.md#install-ghc) setting (including if that is set on the command line) If Stack is checking for the Stack-supplied MSYS2 when Stack is setting up the environment, enables/disables the download and installation of MSYS2 when necessary. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#install-msys). To skip entirely checking for the Stack-supplied MSYS2, see the documentation for the [`skip-msys`](yaml/non-project.md#skip-msys) configuration option. ## `--jobs` or `-j` option Pass the option `--jobs ` to specify the number of concurrent jobs (Stack actions during building) to run. When [building GHC from source](yaml/non-project.md#building-ghc-from-source), specifies the `-j[]` flag of GHC's Hadrian build system. By default, Stack specifies a number of concurrent jobs equal to the number of CPUs (cores) that the machine has. In some circumstances, that default can cause some machines to run out of memory during building. If those circumstances arise, specify `--jobs 1`. This configuration option is distinct from GHC's own `-j[]` flag, which relates to parallel compilation of modules within a package. For further information, see the documentation for the corresponding non-project specific configuration option: [`jobs`](yaml/non-project.md#jobs). ## `--local-bin-path` option Pass the option `--local-bin-path ` to set the target directory for [`stack build --copy-bins`](../commands/build_command.md#-no-copy-bins-flag) and `stack install`. An absolute or relative path can be specified. A relative path at the command line is always assumed to be relative to the current directory. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#local-bin-path). ## `--lock-file` option Default: `read-write`, if snapshot specified in the project-level configuration file; `read-only`, if a different snapshot is specified on the command line. Pass the option `--lock-file ` to specify how Stack interacts with lock files. Valid modes are: * `error-on-write`: Stack reports an error, rather than write a lock file; * `ignore`: Stack ignores lock files; * `read-only`: Stack only reads lock files; and * `read-write`: Stack reads and writes lock files. ## `--[no-]modify-code-page` flag Restrictions: Windows systems only Default: Enabled Enables/disables setting the codepage to support UTF-8. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#modify-code-page). ## `--nix*` flags and options Stack can be configured to integrate with Nix. For further information, see `stack --nix-help` or the [Nix integration](../topics/nix_integration.md) documentation. ## `--numeric-version` flag Pass the flag `--numeric-version` to cause Stack to report its numeric version to the standard output stream (e.g. `2.9.1`) and quit. ## `--[no-]plan-in-log` flag [:octicons-tag-24: 2.13.1](https://github.com/commercialhaskell/stack/releases/tag/v2.13.1) Default: Disabled Enables/disables the logging of build plan construction in debug output. Information about the build plan construction can be lengthy. If you do not need it, it is best omitted from the debug output. ## `--resolver` option A synonym for the [`--snapshot` option](#-snapshot-option) to specify the snapshot resolver. ## `--[no-]rsl-in-log` flag [:octicons-tag-24: 2.9.1](https://github.com/commercialhaskell/stack/releases/tag/v2.9.1) Default: Disabled Enables/disables the logging of the raw snapshot layer (rsl) in debug output. Information about the raw snapshot layer can be lengthy. If you do not need it, it is best omitted from the debug output. ## `--[no-]script-no-run-compile` flag Default: Disabled Enables/disables the use of options `--no-run --compile` with the [`stack script` command](../commands/script_command.md). ## `--silent` flag Equivalent to the `--verbosity silent` option. ## `--[no-]skip-ghc-check` option Default: Disabled Enables/disables the skipping of checking the GHC version and architecture. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#skip-ghc-check). ## `--[no-]skip-msys` option Restrictions: Windows systems only Default: Disabled Enables/disables the skipping of checking for the Stack-supplied MSYS2 (and installing that MSYS2, if it is not installed) when Stack is setting up the environment. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#skip-msys). To prevent installation of MSYS2, if it is not installed, see the documentation for the [`install-msys`](yaml/non-project.md#install-msys) configuration option. ## `--snapshot` option [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Pass the option `--snapshot ` to specify the snapshot. For further information, see the [`snapshot`](yaml/project.md#snapshot) project-specific configuration option documentation. At the command line (only): * `--snapshot lts-` specifies the latest Stackage LTS Haskell snapshot with the specified major version; * `--snapshot lts` specifies, from those with the greatest major version, the latest Stackage LTS Haskell snapshot; * `--snapshot nightly` specifies the most recent Stackage Nightly snapshot; and * `--snapshot global` specifies the snapshot specified by the project-level configuration file in the `global-project` directory in the [Stack root](../topics/stack_root.md#global-project-directory). ## `--stack-colors` or `--stack-colours` options Pass the option `--stack-colors ` to specify Stack's output styles. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#stack-colors). ## `--stack-root` option Overrides: `STACK_ROOT` environment variable Pass the option `--stack-root ` to specify the path to the [Stack root](../topics/stack_root.md) directory.

Possible levels are `silent`, `error`, `warn`, `info` and `debug`, in order of increasing amounts of information provided by logging. ## `--version` flag Pass the flag `--version` to cause Stack to report its version to standard output and quit. For versions that are release candidates, the report will list the dependencies that Stack has been compiled with. ## `--with-gcc` option Pass the option `--with-gcc ` to specify use of a GCC executable. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#with-gcc). ## `--with-hpack` option Pass the option `--with-hpack ` to specify use of an Hpack executable. For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#with-hpack). ## `--work-dir` option Default: `.stack-work` Overrides: [`STACK_WORK`](environment_variables.md#stack_work) environment variable, and [`work-dir`](yaml/non-project.md#work-dir) non-project specific configuration option. Pass the option `--work-dir ` to specify the path to Stack's work directory, within a local project or package directory. The path must be a relative one, relative to the the root directory of the project or package. The relative path cannot include a `..` (parent directory) component. ## `--zsh-completion-script` option Visibility: Hidden See the [shell auto-completion](../topics/shell_autocompletion.md) documentation. ## `--setup-info-yaml` command option Default: `https://raw.githubusercontent.com/commercialhaskell/stackage-content/master/stack/stack-setup-2.yaml` The `--setup-info-yaml ` command option specifies the location of a `setup-info` dictionary.

For further information, see the documentation for the corresponding non-project specific configuration [option](yaml/non-project.md#snapshot-location-base). ## `--help` or `-h` command flags If Stack is passed the `--help` (or `-h`) command flag, it will output help for the command. stack-3.7.1/doc/configure/index.md0000644000000000000000000000331114651506553015204 0ustar0000000000000000--- Title: Configure ---
# Configuration (advanced) Some of Stack's features will not be needed regularly or by all users. This part of the guide and the part on Stack's [commands](../commands/index.md) provide information about those features, organised as a reference guide. Some of the features are complex and separate pages are dedicated to them. The behaviour of Stack is configurable using environment variables, YAML configuration files, global flags and options on the command line and customisation scripts. ## Environment variables The existence or content of certain environment variables can affect how Stack behaves. For further information, see the [environment variables](environment_variables.md) documentation. ## Configuration files Stack is configured by the content of files in the YAML formal. A global configuration file contains non-project specific options. A project-level configuration file contains project-specific options and may contain non-project specific options. For further information, see the [configuration](yaml/index.md) documentation. ## Global flags and options Stack can also be configured by flags and options on the command line. Global flags and options apply to all of Stack's commands. For further information, see the [global flags and options](global_flags.md) documentation. ## Customisation scripts Stack's behaviour can also be affected by customisation scripts. For further information, see the [customisation scripts](customisation_scripts.md) documentation. stack-3.7.1/doc/configure/yaml/index.md0000644000000000000000000001016314765330072016146 0ustar0000000000000000--- title: Configuration files ---
# Configuration files Stack is configured by the content of files in the [YAML](https://yaml.org/) format. ## Project-specific and non-project specific options Stack's configuration options are each of one of two types:
- :material-account:{ .lg .middle } __Project-specific__ Configured only at the project level --- [:octicons-arrow-right-24: Learn more](project.md) - :material-account-multiple:{ .lg .middle } __Non-project specific__ Configured globally or at the project level. --- [:octicons-arrow-right-24: Learn more](non-project.md)
Most of Stack's configuration options are non-project specific. ## Project-level and global configuration files Stack's configuration files are each of one of two types:
- :material-language-haskell:{ .lg .middle } __Project-level__ Named `stack.yaml` by default. --- Contains [project-specific](project.md) options and may contain [non-project-specific](non-project.md) options. Non-project-specific options in the project-level configuration file in the `global-project` directory (see below) are ignored by Stack. - :octicons-globe-24:{ .lg .middle } __Global__ Named `config.yaml`. There is a user-specific file and there may be a system-wide one. If a user-specific file does not exist, then Stack will create one. --- Contains [non-project-specific](non-project.md) options. An option set in the user-specific file will override a corresponding option set in the system-wide file (if it exists).
## Location of project-level configuration Stack obtains project-level configuration from one of the following (in order of preference): 1. A file specified by the `--stack-yaml` command line option. 2. A file specified by the `STACK_YAML` environment variable. 3. A file named `stack.yaml` in the current directory or an ancestor directory. 4. A file name `stack.yaml` in the `global-project` directory in the [Stack root](../../topics/stack_root.md). ## Location of global configuration The default location of global configuration files depends on the operating system and, in the case of the user-specific file, whether Stack is configured to use the XDG Base Directory Specification. An absolute path to these files can be specified by the [`STACK_CONFIG`](../environment_variables.md#stack_config) and [`STACK_GLOBAL_CONFIG`](../environment_variables.md#stack_config) environment variables, respectively. === "Unix-like" The default locations are: * system-wide: `/etc/stack/config.yaml`; and * user-specific: `config.yaml` in the [Stack root](../../topics/stack_root.md). !!! note For compatibility with Stack 0.1.5.0 and earlier, if deprecated file `/etc/stack/config` exists, then Stack will use it instead of `/etc/stack/config.yaml`. === "Windows" The default locations are: * system-wide: none; and * user-specific: `config.yaml` in the [Stack root](../../topics/stack_root.md). === "XDG Base Directory Specification" On Unix-like operating systems and Windows, Stack can be configured to follow the XDG Base Directory Specification if the environment variable `STACK_XDG` is set to any non-empty value. However, Stack will ignore that configuration if the [Stack root](../../topics/stack_root.md) location has been set on the command line or the `STACK_ROOT` environment variable exists. If Stack is following the XDG Base Directory Specification, the location of `config.yaml` (for user-specific options) is `/stack`. If the `XDG_CONFIG_HOME` environment variable does not exist, the default is `~/.config/stack` on Unix-like operating systems and `%APPDATA%\stack` on Windows. stack-3.7.1/doc/configure/yaml/non-project.md0000644000000000000000000017072515023557531017307 0ustar0000000000000000
# Non-project-specific configuration Non-project configuration options can be included in: * a [project-level configuration file](../yaml/index.md#project-level-and-global-configuration-files) (`stack.yaml`, by default), like [project-specific](project.md) ones; or * [global configuration files](../yaml/index.md#project-level-and-global-configuration-files) (`config.yaml`). However, non-project-specific options in the project-level configuration file in the `global-project` directory are ignored by Stack. The options below are listed in alphabetic order. ## allow-different-user [:octicons-tag-24: 1.0.1.0](https://github.com/commercialhaskell/stack/releases/tag/v1.0.1.0) Restrictions: POSIX systems only. Default: `false` Command line equivalent (takes precedence): `--[no-]allow-different-user` flag Allow users other than the owner of the [Stack root](../../topics/stack_root.md) to use the Stack installation. ~~~yaml allow-different-user: true ~~~ The intention of this option is to prevent file permission problems, for example as the result of a Stack command executed under `sudo`. The option is automatically enabled when Stack is re-spawned in a Docker process. ## allow-newer [:octicons-tag-24: 0.1.8.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.8.0) Default: `false` Command line equivalent (takes precedence): [`stack build --[no-]allow-newer`](../../commands/build_command.md#-no-allow-newer-flag) flag Whether to ignore lower and upper version bounds in Cabal files. !!! info The name `allow-newer` was chosen to match a commonly-used Cabal option which ignored only upper bounds. ~~~yaml allow-newer: true ~~~ ## allow-newer-deps [:octicons-tag-24: 2.9.3](https://github.com/commercialhaskell/stack/releases/tag/v2.9.3) Default: `none` Determines a subset of packages to which `allow-newer` should apply. This option has no effect (but warns) if `allow-newer` is `false`. ~~~yaml allow-newer-deps: - foo - bar ~~~ ## apply-ghc-options [:octicons-tag-24: 0.1.6.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.6.0) Default: `locals` Related command line: [`stack build --ghc-options`](../../commands/build_command.md#-ghc-options-option) option Determines to which packages any GHC command line options specified on the command line are applied. Possible values are: `everything` (all packages, project packages or otherwise), `locals` (all project packages, targets or otherwise), and `targets` (all project packages that are targets). !!! note The use of `everything` can break invariants about your snapshot database. !!! info Before Stack 0.1.6.0, the default value was `targets`. ## apply-prog-options [:octicons-tag-24: 2.11.1](https://github.com/commercialhaskell/stack/releases/tag/v2.11.1) Default: `locals` Related command line: [`stack build --PROG-option`](../../commands/build_command.md#-prog-option-options) options Determines to which packages all and any `--PROG-option` command line options specified on the command line are applied. Possible values are: `everything` (all packages, project packages or otherwise), `locals` (all project packages, targets or otherwise), and `targets` (all project packages that are targets). !!! note The use of `everything` can break invariants about your snapshot database. ## arch Default: The machine architecture on which Stack is running. Command line equivalent (takes precedence): [`--arch`](../global_flags.md#-arch-option) option Stack identifies different GHC executables by platform (operating system and machine architecture), (optional) GHC variant and (optional) GHC build. See [`setup-info`](#setup-info). `arch` sets the machine architecture. Values can be those recognized by Cabal (the library) (which are case-insensitive and include `i386`, `x86_64`, and `aarch64` / `arm64`), or other values (which are case-sensitive and treated as an unknown 'other' architecture of the specified name). By default, Stack will warn the user if the specified machine architecture is an unknown 'other' architecture. The warning can be muted; see [`notify-if-arch-unknown`](#notify-if-arch-unknown) !!! note The machine architecture on which Stack is running is as classified by Cabal (the library). Cabal does not distinguish between certain architectures. Examples are `ppc64`/`powerpc64`/`powerpc64le` (classified as `ppc64`) and `arm`/`armel`/`armeb` (classified as `arm`). !!! note As Cabal (the library) does not distinguish between machine architectures `powerpc64` and `powerpc64le`, the latter can be specified in Stack's configuration as an 'other' architecture, such as `arch: ppc64le`. ## build [:octicons-tag-24: 1.1.0](https://github.com/commercialhaskell/stack/releases/tag/v1.1.0) Default: ~~~yaml build: library-profiling: false executable-profiling: false library-stripping: true executable-stripping: true # NOTE: global usage of haddock can cause build failures when documentation is # incorrectly formatted.

Allows setting build options which are usually specified on the command line. The meanings of these settings correspond directly with the command line flags of the same name. For further information, see the [`stack build`](../../commands/build_command.md) command documentation. ## casa [:octicons-tag-24: 2.13.1](https://github.com/commercialhaskell/stack/releases/tag/v2.13.1) Default: ~~~yaml casa: enable: true # Use a Casa server? repo-prefix: https://casa.stackage.org # Unless casa-repo-prefix is set. max-keys-per-request: 1280 # Maximum number of keys per request. ~~~ This option specifies whether or not Stack should use a Casa (content-addressable storage archive) server to cache Cabal files and all other files in packages; and, if so, the prefix for the URL used to pull information from the server and the maximum number of keys per request. For further information, see this blog post about [Casa and Stack](https://www.fpcomplete.com/blog/casa-and-stack/). `repo-prefix` replaces [`casa-repo-prefix`](#casa-repo-prefix) (which is deprecated) and has precedence if both keys are set. ## casa-repo-prefix [:octicons-tag-24: 2.3.1](https://github.com/commercialhaskell/stack/releases/tag/v2.3.1) Deprecated in favour of [`casa`](#casa), which takes precedence if present. Default: `https://casa.stackage.org` This option specifies the prefix for the URL used to pull information from the Casa server. ## color Command line equivalent (takes precedence): `--color` option This option specifies when to use color in output. The option is used as `color: `, where `` is 'always', 'never', or 'auto'. On Windows versions before Windows 10, for terminals that do not support color codes, the default is 'never'; color may work on terminals that support color codes. (The British English spelling (colour) is also accepted. In configuration files, the American spelling is the alternative that has priority.) ## compiler [:octicons-tag-24: 0.1.8.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.8.0) Command line equivalent (takes precedence): `--compiler` option Overrides the compiler version in the snapshot. Note that the `compiler-check` flag also applies to the version numbers. This uses the same syntax as compiler snapshots like `ghc-9.8.4`. This can be used to override the compiler for a Stackage snapshot, like this: ~~~yaml snapshot: lts-23.24 compiler: ghc-9.8.3 compiler-check: match-exact ~~~ ### Building GHC from source :octicons-beaker-24: Experimental [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Stack supports building the GHC compiler from source, using [Hadrian](https://gitlab.haskell.org/ghc/ghc/blob/master/hadrian/README.md) (the build system for GHC). The GHC version to build and to use is defined by a a Git commit ID and a Hadrian "flavour", with the following syntax: ~~~yaml compiler: ghc-git-- ~~~ In the following example the commit ID is "5be7ad..." and the flavour is "quick": ~~~yaml compiler: ghc-git-5be7ad7861c8d39f60b7101fd8d8e816ff50353a-quick ~~~ By default, the code is retrieved from the main GHC repository. If you want to select another repository, use the `compiler-repository` option: ~~~yaml compiler-repository: git://my/ghc/repository # default # compiler-repository: https://gitlab.haskell.org/ghc/ghc.git ~~~ Stack does not check the compiler version when it uses a compiler built from source. It is assumed that the built compiler is recent enough as Stack doesn't enable any known workaround to make older compilers work. Building the compiler can take a very long time (more than one hour). For faster build times, use Hadrian flavours that disable documentation generation. ### Bootstrap compiler Building GHC from source requires a working GHC (known as the bootstrap compiler). As we use a Stack based version of Hadrian (`hadrian/build-stack` in GHC sources), the bootstrap compiler is configured into `hadrian/stack.yaml` and fully managed by Stack. !!! note For some commit IDs, the snapshot specified in `hadrian/stack.yaml` specifies a version of GHC that cannot be used to build GHC. This results in GHC's `configure` script reporting messages similar to the following before aborting: ~~~text checking version of ghc... 9.0.2 configure: error: GHC version 9.2 or later is required to compile GHC. ~~~ The resolution is: (1) to specify an alternative snapshot (one that specifies a sufficiently recent version of GHC) on the command line, using Stack's option `--snapshot `. Stack will use that snapshot when running GHC's `configure` script; and (2) to set the contents of the `STACK` environment variable to be `stack --snapshot `. Hadrian's `build-stack` script wil refer to that environment variable for the Stack command it uses. ### Hadrian prerequisites The Hadrian build system has certain [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation). It requires certain versions of the `happy` and `alex` executables on the PATH. Stack will build and install `happy` and `alex`, if not already on the PATH. === "macOS" Hadrian requires, or case use, certain tools or Python packages that do not come with macOS by default and that need to be installed using `brew` or `pip3` (Python). Hadrian's LaTeX documentation also requires the [DejaVu fonts](https://dejavu-fonts.github.io/) to be installed. ~~~zsh brew install python@3.11 # GHC uses a Python script named `boot`. brew install automake # Tool for generating GNU Standards-compliant Makefiles. brew install texinfo # Official documentation format of the GNU project. pip3 install -U sphinx # Sphinx is the Python documentation generator. brew install --cask mactex # MacTeX: Full TeX Live distribution with GUI applications ~~~ === "Windows" Hadrian requires, or can use, certain MSYS2 or Python packages that do not come with the Stack-supplied MSYS2 by default and need to be installed using `pacman` (MSYS2) or `pip` (Python). Hadrian's LaTeX documentation also requires the [DejaVu fonts](https://dejavu-fonts.github.io/) to be installed. ~~~pwsh stack exec -- pacman --sync --refresh # Synchronize MSYS2 package databases stack exec -- pacman --sync mingw-w64-x86_64-python-pip # The PyPA recommended tool (pip) for installing Python packages. Also # installs Python as a dependency. GHC uses a Python script named `boot`. # The package must be the one from the `mingw64` MSYS2 repository, as Python # from the `msys` repository cannot interpret Windows file paths correctly. stack exec -- pacman --sync mingw-w64-x86_64-autotools # The GNU autotools build system, including `autoreconf`, `aclocal` # and `make`. GHC uses a sh script named `configure` which is itself created # from a file named `configure.ac`. stack exec -- pacman --sync patch # A utility to apply patch files to original sources. stack exec -- pacman --sync texinfo # Utilities to work with and produce manuals, ASCII text, and on-line # documentation from a single source file, including `makeinfo`. stack exec -- pacman --sync mingw-w64-x86_64-ca-certificates # Common CA (certificate authority) certificates. stack exec -- pip install -U sphinx # Sphinx is the Python documentation generator. ~~~ Hadrian may require certain LaTeX packages and may prompt for these to be installed duing the build process. ### Global packages The GHC compiler you build from sources may depend on unreleased versions of some global packages (e.g. Cabal). It may be an issue if a package you try to build with this compiler depends on such global packages because Stack may not be able to find versions of those packages (on Hackage, etc.) that are compatible with the compiler. The easiest way to deal with this issue is to use the [`drop-packages`](project.md#drop-packages) project-specific configuration option to drop the offending packages as follows. Instead of using the packages specified in the snapshot, the global packages bundled with GHC will be used. ~~~yaml drop-packages: - Cabal - ... ~~~ Another way to deal with this issue is to add the relevant packages as [`extra-deps`](project.md#extra-deps) built from source. To avoid mismatching versions, you can use exactly the same commit id you used to build GHC as follows: ~~~ extra-deps: - git: https://gitlab.haskell.org/ghc/ghc.git commit: '5be7ad7861c8d39f60b7101fd8d8e816ff50353a' subdirs: - libraries/Cabal/Cabal - libraries/... ~~~ ## compiler-check [:octicons-tag-24: 0.1.4.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.4.0) Default: `match-minor` Specifies how the compiler version in the snapshot is matched against concrete versions. Valid values: * `match-minor`: make sure that the first three components match, but allow patch-level differences. For example< 7.8.4.1 and 7.8.4.2 would both match 7.8.4. This is useful to allow for custom patch levels of a compiler. * `match-exact`: the entire version number must match precisely * `newer-minor`: the third component can be increased, e.g. if your snapshot is `ghc-7.10.1`, then 7.10.2 will also be allowed. This was the default up through Stack 0.1.3 ## concurrent-tests [:octicons-tag-24: 0.1.2.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.2.0) Default: `true` This option specifies whether test suites should be executed concurrently with each other. The default is `true` since this is usually fine and it often means that tests can complete earlier. However, if some test suites require exclusive access to some resource, or require a great deal of CPU or memory resources, then it makes sense to set this to `false`. ~~~yaml concurrent-tests: false ~~~ ## configure-options [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Related command line (takes precedence): [`stack build --PROG-option`](../../commands/build_command.md#-prog-option-options) options `configure-options` can specify Cabal (the library) options (including `--PROG-option` or `--PROG-options` options) for the configure step of the Cabal build process for a named package, all project packages that are targets (using the `$targets` key), all project packages (targets or otherwise) (using the `$locals` key), or all packages (project packages or otherwise) (using the `$everything` key). ~~~yaml configure-options: $everything: - --with-gcc - /some/path $locals: - --happy-option=--ghc $targets: # Only works on platforms where GHC supports linking against shared Haskell # libraries: - --enable-executable-dynamic my-package: - --another-flag ~~~ On platforms where GHC supports linking against shared Haskell libraries (that currently excludes Windows), Cabal's `--enable-executable-dynamic` flag (which implies `--enable-shared`, unless `--disable-shared` is specified) links dependent Haskell libraries into executables dynamically. ## connection-count Default: `8` Integer indicating how many simultaneous downloads are allowed to happen. ### default-init-snapshot [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Default: As for the [`stack init`](../../commands/init_command.md) command when no snapshot is specified at the command line. Command line equivalent (takes precedence): [`--snapshot`](../global_flags.md#-snapshot-option) or [`--resolver`](../global_flags.md#-resolver-option) option This option specifies which snapshot to use with `stack init`, when none is specified at the command line. `default-init-snapshot: global` specifies the snapshot specified by the project-level configuration file in the `global-project` directory in the [Stack root](../../topics/stack_root.md#global-project-directory). ## default-template Default: `new-template` in the [stack-templates](https://github.com/commercialhaskell/stack-templates/) repository. This option specifies which template to use with `stack new`, when none is specified. Other templates are listed in the [stack-templates](https://github.com/commercialhaskell/stack-templates/) repository. See the output of `stack templates`. ## docker Command line equivalents: `--docker-*` flags and options (see `stack --docker-help` for details). For further information, see the [Docker integration](../../topics/docker_integration.md#configuration) documentation. ## dump-logs [:octicons-tag-24: 1.3.0](https://github.com/commercialhaskell/stack/releases/tag/v1.3.0) Default: `warning` Command line equivalent (takes precedence): `--[no-]dump-logs` flag In the case of *non-interleaved* output and *more than one* target package, Stack sends the build output from GHC for each target package to a log file, unless an error occurs that prevents that. For further information, see the [`stack build --[no-]interleaved-output` flag](../../commands/build_command.md#-no-interleaved-output-flag) documentation. The value of the `dump-logs` key controls what, if any, log file content is sent ('dumped') to the standard error stream of the console at the end of the build. Possible values are: ~~~yaml dump-logs: none # don't dump the content of any log files dump-logs: warning # dump the content of any log files that include GHC warnings dump-logs: all # dump the content of all log files ~~~ At the command line, `--no-dump-logs` is equivalent to `dump-logs: none` and `--dump-logs` is equivalent to `dump-logs: all`. If GHC reports an error during the build and a log file is created, that build output will be included in the log file. Stack will also report errors during building to the standard error stream. That stream can be piped to a file. For example, for a file named `stderr.log`: ~~~text stack --no-dump-logs --color always build --no-interleaved-output 2> stderr.log ~~~ ## extra-include-dirs Default: `[]` Command line equivalent: `--extra-include-dirs` option (repeat for each directory) A list of extra paths to be searched for header files. Paths should be absolute ~~~yaml extra-include-dirs: - /opt/foo/include ~~~ Since these are system-dependent absolute paths, it is recommended that you specify these in your `config.yaml` file. If you control the build environment in your project's ``stack.yaml``, perhaps through docker or other means, then it may well make sense to include these there as well. ## extra-lib-dirs Default: `[]` Command line equivalent: `--extra-lib-dirs` option (repeat for each directory) A list of extra paths to be searched for libraries. Paths should be absolute ~~~yaml extra-lib-dirs: - /opt/foo/lib ~~~ Since these are system-dependent absolute paths, it is recommended that you specify these in your `config.yaml` file. If you control the build environment in your project's ``stack.yaml``, perhaps through Docker or other means, then it may well make sense to include these there as well. ## extra-path [:octicons-tag-24: 0.1.4.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.4.0) This option specifies additional directories to prepend to the PATH. These will be used when resolving the location of executables, and will also be visible in the PATH of processes run by Stack. For example, to prepend `/path-to-some-dep/bin` to your PATH: ~~~yaml extra-path: - /path-to-some-dep/bin ~~~ Other paths added by Stack - things like the project's binary directory and the compiler's binary directory - will take precedence over those specified here (the automatic paths get prepended). ## file-watch-hook [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Specifies the location of an executable or `sh` shell script to be run after each attempted build with [`build --file-watch`](../../commands/build_command.md#-file-watch-flag). An absolute or relative path can be specified. Changes to the configuration after the initial `build --file-watch` command are ignored. If the project-level configuration is provided in the `global-project` directory in the [Stack root](../../topics/stack_root.md), a relative path is assumed to be relative to the current directory. Otherwise, it is assumed to be relative to the directory of the project-level configuration file. ## ghc-build [:octicons-tag-24: 1.3.0](https://github.com/commercialhaskell/stack/releases/tag/v1.3.0) Default: `standard` Command line equivalent (takes precedence): `--ghc-build` option Stack identifies different GHC executables by platform (operating system and machine architecture), (optional) GHC variant and (optional) GHC build. See [`setup-info`](#setup-info). `ghc-build` specifies a specialized architecture for the GHC executable. Normally this is determined automatically, but it can be overridden. Possible arguments include `standard`, `gmp4`, `nopie`, `tinfo6`, `tinfo6-libc6-pre232`, `tinfo6-nopie`, `ncurses6`, `int-native` and `integersimple`. ## ghc-options [:octicons-tag-24: 0.1.4.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.4.0) Default: `{}` Related command line (takes precedence): [`stack build --ghc-options`](../../commands/build_command.md#-ghc-options-option) option GHC command line options can be specified for a package in its Cabal file (including one created from a `package.yaml` file). This option augments and, if applicable (see below), overrides any such GHC command line options. `ghc-options` can specify GHC command line options for a named package, all project packages that are targets (using the `$targets` key), all project packages (targets or otherwise) (using the `$locals` key), or all packages (project packages or otherwise) (using the `$everything` key). ~~~yaml ghc-options: "$everything": -O2 "$locals": -Wall "$targets": -Werror some-package: -DSOME_CPP_FLAG ~~~ GHC's command line options are _order-dependent_ and evaluated from left to right. Later options can override the effect of earlier ones. Stack applies options (as applicable) in the order of `$everything`, `$locals`, `$targets`, and then those for the named package. Any GHC command line options for a package specified at Stack's command line are applied after those specified in Stack's configuration files. Since Stack 1.6.1, setting a GHC options for a specific package will automatically promote it to a project package (much like setting a custom package flag). However, setting options via `$everything` on all flags will not do so (see [GitHub discussion](https://github.com/commercialhaskell/stack/issues/849#issuecomment-320892095) for reasoning). This can lead to unpredictable behavior by affecting your snapshot packages. !!! info Before Stack 1.6.1, the key `*` (then deprecated) had the same function as the key `$everything`. ## ghc-variant [:octicons-tag-24: 0.1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.5.0) Default: `standard` Command line equivalent (takes precedence): `--ghc-variant` option Stack identifies different GHC executables by platform (operating system and machine architecture), (optional) GHC variant and (optional) GHC build. See [`setup-info`](#setup-info). `ghc-variant` specifies a variant of the GHC executable. Known values are: * `standard`: Use the standard GHC binary distribution * `int-native`: From GHC 9.4.1, use a GHC bindist that uses the Haskell-native big-integer [backend](https://downloads.haskell.org/~ghc/9.0.2/docs/html/users_guide/9.0.1-notes.html#highlights). For further information, see this [article](https://iohk.io/en/blog/posts/2020/07/28/improving-haskells-big-numbers-support/). * `integersimple`: Use a GHC bindist that uses [integer-simple instead of GMP](https://ghc.haskell.org/trac/ghc/wiki/ReplacingGMPNotes) * any other value: Use a custom GHC bindist. You should specify [setup-info](#setup-info) or [setup-info-locations](#setup-info-locations) so `stack setup` knows where to download it, or pass the `stack setup --ghc-bindist` argument on the command-line This option is incompatible with `system-ghc: true`. ## global-hints-location [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Default: ~~~yaml global-hints-location: url: https://raw.githubusercontent.com/commercialhaskell/stackage-content/master/stack/global-hints.yaml ~~~ (as set in the `pantry` library) Sets the location of the global hints YAML file. The location can be either a filepath of a local file or a URL. The filepath can be absolute or relative to the Stack root. For example: ~~~yaml global-hints-location: filepath: \pantry\global-hints.yaml ~~~ or: ~~~yaml global-hints-location: url: https://example.com/global-hints/location/global-hints.yaml ~~~ ## hackage-base-url [:octicons-tag-24: 1.9.1](https://github.com/commercialhaskell/stack/releases/tag/v1.9.1) Default: `https://hackage.haskell.org/` Sets the address of the Hackage server to upload the package to. ~~~yaml hackage-base-url: https://hackage.example.com/ ~~~ ## hide-source-paths Default: `true` ([:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1)) Whether to use the `-fhide-source-paths` option by default for GHC >= 8.2: ~~~yaml hide-source-paths: false ~~~ Build output when enabled: ~~~text ... [1 of 2] Compiling Lib [2 of 2] Compiling Paths_test_pr ... ~~~ Build output when disabled: ~~~text ... [1 of 2] Compiling Lib ( src/Lib.hs, .stack-work/dist/x86_64-linux-tinfo6/Cabal-2.4.0.1/build/Lib.o ) ... ~~~ ## hide-th-loading Default: `true` Strip out the "Loading ..." lines from GHC build output, produced when using Template Haskell. ## hpack-force [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Default: `false` Command line equivalent (takes precedence): [`--hpack-force` option](../global_flags.md#-no-hpack-force-flag) Whether or not to allow Hpack to overwrite a Cabal file that has been modified manually. By default, Hpack 0.20.0 or later will decline to overwrite such a Cabal file. ## ignore-revision-mismatch (Removed 1.11) This flag was introduced in Stack 1.6, and removed on the move to Pantry. You will receive a warning if this configuration value is set. ## install-ghc Default: `true` ([:octicons-tag-24: 1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v1.5.0)) Command line equivalent (takes precedence): [`--[no-]install-ghc`](../global_flags.md#-no-install-ghc-flag) flag Whether or not to download and install GHC when necessary. On Windows, `install-ghc: false` also disables the download and installation of the Stack-supplied MSYS2 when necessary. ## install-msys [:octicons-tag-24: 3.5.1](https://github.com/commercialhaskell/stack/releases/tag/v3.5.1) Restrictions: Windows systems only Default: same as the [`install-ghc`](#install-ghc) setting (including if that is set on the command line) Command line equivalent (takes precedence): [`--[no-]install-msys`](../global_flags.md#-no-install-msys-flag) flag If Stack is checking for the Stack-supplied MSYS2 when Stack is setting up the environment, whether or not to download and install MSYS2 when necessary. To skip entirely checking for the Stack-supplied MSYS2, see the documentation for the [`skip-msys`](#skip-msys) configuration option. ## jobs Default: the number of CPUs (cores) that the machine has. Command line equivalent (takes precedence): [`-j`, `--jobs` option](../global_flags.md#-jobs-or-j-option) Specifies the number of concurrent jobs (principally, Stack actions during building - see further below) to run. When [building GHC from source](#building-ghc-from-source), specifies the `-j[]` flag of GHC's Hadrian build system. In some circumstances, the default can cause some machines to run out of memory during building. If those circumstances arise, specify `jobs: 1`. This configuration option is distinct from GHC's own `-j[]` flag, which relates to parallel compilation of modules within a package. ## local-bin-path Default (on Unix-like operating systems): `~/.local/bin` Default (on Windows): `%APPDATA%\local\bin` Command line equivalent (takes precedence): `--local-bin-path` option Specifies the target directory for [`stack build --copy-bins`](../../commands/build_command.md#-no-copy-bins-flag) and `stack install`. An absolute or relative path can be specified. If the project-level configuration is provided in the `global-project` directory in the [Stack root](../../topics/stack_root.md), a relative path is assumed to be relative to the current directory. Otherwise, it is assumed to be relative to the directory of the project-level configuration file. ## local-programs-path [:octicons-tag-24: 1.3.0](https://github.com/commercialhaskell/stack/releases/tag/v1.3.0) This overrides the location of the Stack 'programs' directory, where tools like GHC get installed. The path must be an absolute one. Stack's defaults differ between Unix-like operating systems and Windows. === "Unix-like" Default: `programs` directory in the [Stack root](../../topics/stack_root.md). === "Windows" Default: `$Env:LOCALAPPDATA\Programs\stack`, if the `LOCALAPPDATA` environment variable exists. Otherwise, the `programs` directory in the [Stack root](../../topics/stack_root.md). The MSYS2 tool is also installed in the Stack 'programs' directory. !!! warning "Space character in the path to Stack's 'programs' directory" If there is a space character in the path to Stack's 'programs' directory this may cause problems: * with building packages that make use of the GNU project's `autoconf` package and `configure` shell script files. That may be the case particularly if there is no corresponding short name ('8 dot 3' name) for the directory in the path with the space (which may be the case if '8 dot 3' names have been stripped or their creation not enabled by default). Examples of packages on Hackage that make use of `configure` are `network` and `process`; and * building with GHC 9.4.1 and later. These versions of GHC have a bug which means they do not work if the path to the `ghc` executable has a space in it. The default location for Stack's 'programs' directory will have a space in the path if the value of the `USERNAME` environment variable includes a space. If there are problems building, it will be necessary to specify an alternative path that does not contain spaces. For example, the `programs` directory in the [Stack root](../../topics/stack_root.md) (assuming that path is space-free). For example, if the relevant directory is `C:\sr\programs`, add: ~~~yaml local-programs-path: C:\sr\programs ~~~ to Stack's [global configuration](https://docs.haskellstack.org/en/stable/configure/yaml/#location-of-global-configuration) file (`config.yaml`). If that global configuration file does not yet exist, command: ~~~text stack --no-install-ghc setup ~~~ to cause Stack to create it (without also installing GHC). === "Windows (Command Prompt)" Default: `%LOCALAPPDATA%\Programs\stack`, if the `LOCALAPPDATA` environment variable exists. Otherwise, the `programs` directory in the [Stack root](../../topics/stack_root.md). The MSYS2 tool is also installed in the Stack 'programs' directory. !!! warning "Space character in the path to Stack's 'programs' directory" If there is a space character in the path to Stack's 'programs' directory this may cause problems: * with building packages that make use of the GNU project's `autoconf` package and `configure` shell script files.

If that global configuration file does not yet exist, command: ~~~text stack --no-install-ghc setup ~~~ to cause Stack to create it (without also installing GHC). ## modify-code-page [:octicons-tag-24: 0.1.6.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.6.0) Restrictions: Windows systems only. Default: `true` Command line equivalent (takes precedence): `--[no-]modify-code-page` flag Whether to modify the code page for UTF-8 output. ~~~yaml modify-code-page: false ~~~ ## msys-environment [:octicons-tag-24: 3.1.1](https://github.com/commercialhaskell/stack/releases/tag/v3.1.1) Restrictions: Windows systems only. Default: `MINGW64` (64-bit Windows) or `MINGW32` (32-bit Windows) The name of the MSYS2 environment (case-sensitive) used in the Stack environment. Valid environments are `CLANG32`, `CLANG64`, `CLANGARM64`, `MINGW32`, `MINGW64`, and `UCRT64`. ## nix [:octicons-tag-24: 0.1.10.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.10.0) Default: ~~~yaml nix: enable: false # Except on NixOS, where `enable: true` pure: true packages: [] shell-file: nix-shell-options: [] path: [] add-gc-roots: false ~~~ Command line equivalents: `--nix-*` flags and options (see `stack --nix-help` for details). For further information, see the [Nix integration](../../topics/nix_integration.md#non-project-specific-configuration) documentation. ## notify-if-arch-unknown [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Default: `true` If the specified machine architecture value is unknown to Cabal (the library), should Stack notify the user of that? ## notify-if-cabal-untested [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Default: `true` If Stack has not been tested with the version of Cabal (the library) that has been found, should Stack notify the user of that? ## notify-if-ghc-untested [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Default: `true` If Stack has not been tested with the version of GHC that is being used, should Stack notify the user of that? ## notify-if-nix-on-path [:octicons-tag-24: 2.15.1](https://github.com/commercialhaskell/stack/releases/tag/v2.15.1) Default: `true` If Stack's integration with the Nix package manager is not enabled, should Stack notify the user if a `nix` executable is on the PATH? ## notify-if-no-run-benchmarks [:octicons-tag-24: 3.3.1](https://github.com/commercialhaskell/stack/releases/tag/v3.3.1) Default: `true` Should Stack notify the user if the automatic running of a benchmark is prevented by the `--no-run-benchmarks` flag? ## notify-if-no-run-tests [:octicons-tag-24: 3.3.1](https://github.com/commercialhaskell/stack/releases/tag/v3.3.1) Default: `true` Should Stack notify the user if the automatic running of a test suite is prevented by the `--no-run-tests` flag? ## package-index [:octicons-tag-24: 2.9.3](https://github.com/commercialhaskell/stack/releases/tag/v2.9.3) Default: ~~~yaml package-index: download-prefix: https://hackage.haskell.org/ hackage-security: keyids: - 0a5c7ea47cd1b15f01f5f51a33adda7e655bc0f0b0615baa8e271f4c3351e21d - 1ea9ba32c526d1cc91ab5e5bd364ec5e9e8cb67179a471872f6e26f0ae773d42 - 2c6c3627bd6c982990239487f1abd02e08a02e6cf16edb105a8012d444d870c3 - 51f0161b906011b52c6613376b1ae937670da69322113a246a09f807c62f6921 - fe331502606802feac15e514d9b9ea83fee8b6ffef71335479a2e68d84adc6b0 key-threshold: 3 ignore-expiry: true ~~~ Specify the package index. The index must use the [Hackage Security](https://hackage.haskell.org/package/hackage-security) format. This setting is most useful for providing a mirror of the official Hackage server for * bypassing a firewall; or * faster downloads. If the setting specifies an index that does not mirror Hackage, it is likely that will result in significant breakage, including most snapshots failing to work. In the case of Hackage, the keys of its root key holders are contained in the `haskell-infra/hackage-root-keys` [repository](https://github.com/haskell-infra/hackage-root-keys). The Hackage package index is signed. A signature is valid when three key holders have signed. The Hackage timestamp is also signed. A signature is valid when one key holder has signed. If the `hackage-security` key is absent, the Hackage Security configuration will default to that for the official Hackage server. `key-threshold` specifies the minimum number of keyholders that must have signed the package index for it to be considered valid. `ignore-expiry` specifies whether or not the expiration of timestamps should be ignored. !!! info Before Stack 2.1.3, the default for `ignore-expiry` was `false`. For more information, see [issue #4928](https://github.com/commercialhaskell/stack/issues/4928). ## pvp-bounds [:octicons-tag-24: 0.1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.5.0) Default: `none` Command line equivalent (takes precedence): [`stack sdist --pvp-bounds`](../../commands/sdist_command.md) option or [`stack upload --pvp-bounds`](../../commands/upload_command.md) option !!! warning As of Stack 1.6.0, this feature does not reliably work, due to issues with the Cabal library's printer. Stack will generate a warning when a lossy conversion occurs, in which case you may need to disable this setting. For further information, see issue [#3550](https://github.com/commercialhaskell/stack/issues/3550). When using the `sdist` and `upload` commands, this setting determines whether the Cabal file's dependencies should be modified to reflect PVP lower and upper bounds. ### Basic use Values are `none` (unchanged), `upper` (add upper bounds), `lower` (add lower bounds), and both (and upper and lower bounds). The algorithm Stack follows is: * If an upper or lower bound (other than `>= 0` - 'any version') already exists on a dependency, it is left alone * When adding a lower bound, Stack looks at the current version specified by `stack.yaml`, and sets it as the lower bound (e.g., `foo >= 1.2.3`) * When adding an upper bound, Stack sets it as less than the next major version (e.g., `foo < 1.3`) ~~~yaml pvp-bounds: none ~~~ For further information, see the announcement [blog post](https://www.fpcomplete.com/blog/2015/09/stack-pvp). ### Use with Cabal file revisions [:octicons-tag-24: 1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v1.5.0) Each of the values listed above supports adding `-revision` to the end of the value, e.g. `pvp-bounds: both-revision`. This means that, when uploading to Hackage, Stack will first upload your tarball with an unmodified Cabal file, and then upload a Cabal file revision with the PVP bounds added. This can be useful - especially combined with the [Stackage no-revisions feature](http://www.snoyman.com/blog/2017/04/stackages-no-revisions-field) - as a method to ensure PVP compliance without having to proactively fix bounds issues for Stackage maintenance. ## recommend-stack-upgrade [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Default: `true` When Stack notices that a new version of Stack is available, should it notify the user? ## rebuild-ghc-options [:octicons-tag-24: 0.1.6.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.6.0) Default: `false` Should Stack rebuild a package when its GHC options change? The default value reflects that, in most cases, GHC options are used to affect optimization levels and warning behavior, for which GHC does not recompile the modules. !!! info Before Stack 0.1.6.0, Stack rebuilt a package when its GHC options changed. ## require-stack-version Default: `"-any"` Require a version of Stack within the specified range ([cabal-style](https://www.haskell.org/cabal/users-guide/developing-packages.html#build-information)) to be used for this project. Example: `require-stack-version: "== 0.1.*"` ## save-hackage-creds [:octicons-tag-24: 1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v1.5.0) Default: `true` Command line equivalent (takes precedence): [`stack upload --[no]-save-hackage-creds`](../../commands/upload_command.md) option Controls whether, when using `stack upload`, the user's Hackage username and password are stored in a local file. ~~~yaml save-hackage-creds: true ~~~ ## setup-info [:octicons-tag-24: 0.1.5.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.5.0) The `setup-info` dictionary specifies download locations for tools to be installed during set-up, such as GHC or, on Windows, 7z and MSYS2. The dictionary maps `('Tool', 'Platform', 'Version')` to the location where it can be obtained. For example, mapping `(GHC, 64-bit Windows, 9.2.3)` to the URL hosting the archive file for GHC's installation. Possible usages of this configuration option are: 1. Using Stack offline or behind a firewall. 2. Extending the tools known to Stack, such as cutting-edge versions of GHC or builds for custom Linux distributions (for use with the [ghc-variant](#ghc-variant) option). By default, Stack obtains the dictionary from [stack-setup-2.yaml](https://github.com/commercialhaskell/stackage-content/raw/master/stack/stack-setup-2.yaml). The `setup-info` dictionary is constructed in the following order: 1. `setup-info` in the configuration - inline configuration 2. `--setup-info-yaml` command line arguments - URLs or paths. Multiple locations may be specified. 3. `setup-info-locations` in the configuration - URLs or paths. See further below. The format of this key is the same as in the default [stack-setup-2.yaml](https://github.com/commercialhaskell/stackage-content/raw/master/stack/stack-setup-2.yaml). For example, GHC 9.2.3 of custom variant `myvariant` (see further below) on 64-bit Windows: ~~~yaml setup-info: ghc: windows64-custom-myvariant: 9.2.3: url: "https://example.com/ghc-9.2.3-x86_64-unknown-mingw32-myvariant.tar.xz" ~~~ 'Platforms' are pairs of an operating system and a machine architecture (for example, 32-bit i386 or 64-bit x86-64) (represented by the `Cabal.Distribution.Systems.Platform` type). Stack currently (version 2.15.1) supports the following pairs in the format of the `setup-info` key: |Operating system|I386 arch|X86_64 arch|Other machine architectures | |----------------|---------|-----------|------------------------------------------------------------| |Linux |linux32 |linux64 |AArch64: linux-aarch64, Arm: linux-armv7, Sparc: linux-sparc| |OSX |macosx |macosx | | |Windows |windows32|windows64 | | |FreeBSD |freebsd32|freebsd64 |AArch64: freebsd-aarch64 | |OpenBSD |openbsd32|openbsd64 | | For GHC, the distinguishing 'Version' in the key format includes a 'tag' for any (optional) GHC variant (see [ghc-variant](#ghc-variant)) and a further 'tag' for any (optional) specialised GHC build (see [ghc-build](#ghc-build)). The optional variant 'tag' is either `-integersimple` or `-custom-`. For example, for GHC 9.0.2 of specialised GHC build `tinfo6` on x86_64 Linux: ~~~yaml setup-info: ghc: linux64-tinfo6: 9.0.2: url: "http://downloads.haskell.org/~ghc/9.0.2/ghc-9.0.2a-x86_64-fedora27-linux.tar.xz" content-length: 237286244 sha1: affc2aaa3e6a1c446698a884f56a0a13e57f00b4 sha256: b2670e9f278e10355b0475c2cc3b8842490f1bca3c70c306f104aa60caff37b0 ~~~ On Windows, the required 7z executable and DLL tools are represented in the format of the `setup-info` key simply by `sevenzexe-info` and `sevenzdll-info`. This configuration **adds** the specified setup information metadata to the default. Specifying this configuration **does not** prevent the default [stack-setup-2.yaml](https://github.com/commercialhaskell/stackage-content/raw/master/stack/stack-setup-2.yaml) from being consulted as a fallback. If, however, you need to **replace** the default `setup-info` dictionary, use the following: ~~~yaml setup-info-locations: [] ~~~ ## setup-info-locations [:octicons-tag-24: 2.3.1](https://github.com/commercialhaskell/stack/releases/tag/v2.3.1) Command line equivalent (takes precedence): `--setup-info-yaml` option By way of introduction, see the [`setup-info`](#setup-info) option. This option specifies the location(s) of `setup-info` dictionaries. The first location which provides a dictionary that specifies the location of a tool - `('Tool', 'Platform', 'Version')` - takes precedence. For example, you can extend the default tools, with a fallback to the default `setup-info` location, as follows: ~~~yaml setup-info-locations: - C:/stack-offline/my-stack-setup.yaml - relative/inside/my/project/setup-info.yaml - \\smbShare\stack\my-stack-setup.yaml - http://stack-mirror.com/stack-setup.yaml # Fallback to the default location - https://github.com/commercialhaskell/stackage-content/raw/master/stack/stack-setup-2.yaml ~~~ Stack only refers to the default `setup-info` location if no locations are specified in the `setup-info-locations` configuration or on the command line using the `--setup-info-yaml` option. For example, both of the following will cause `stack setup` not to consult the default `setup-info` location: ~~~yaml setup-info-locations: - C:/stack-offline/my-stack-setup.yaml ~~~ and ~~~yaml setup-info-locations: [] ~~~ Relative paths are resolved relative to the `stack.yaml` file (either the one in the local project or the global `stack.yaml`). Relative paths may also be used for the installation paths to tools (such as GHC or 7z). This allows vendoring the tools inside a monorepo (a single repository storing many projects). For example: Directory structure: ~~~text - src/ - installs/ - my-stack-setup.yaml - 7z.exe - 7z.dll - ghc-9.2.3.tar.xz - stack.yaml ~~~ In the project's `stack.yaml`: ~~~yaml setup-info-locations: - installs/my-stack-setup.yaml ~~~ In `installs/my-stack-setup.yaml`: ~~~yaml sevenzexe-info: url: "installs/7z.exe" sevenzdll-info: url: "installs/7z.dll" ghc: windows64: 9.2.3: url: "installs/ghc-9.2.3.tar.xz" ~~~ ## skip-ghc-check Default: `false` Command line equivalent (takes precedence): `--[no-]skip-ghc-check` flag Should we skip the check to confirm that your system GHC version (on the PATH) matches what your project expects? ## skip-msys [:octicons-tag-24: 0.1.2.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.2.0) Restrictions: Windows systems only Default: `false` Command line equivalent (takes precedence): [`--[no-]skip-msys`](../global_flags.md#-no-skip-msys-option) flag Skips checking for the Stack-supplied MSYS2 (and installing that MSYS2, if it is not installed) when Stack is setting up the environment. To prevent installation of MSYS2, if it is not installed, see the documentation for the [`install-msys`](#install-msys) configuration option. ~~~yaml skip-msys: true ~~~ !!! note Usually, the use of this option does not make sense in project-level configuration and it is used only in global configuration. ## snapshot-location-base [:octicons-tag-24: 2.5.1](https://github.com/commercialhaskell/stack/releases/tag/v2.5.1) Default: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/ (as set in the `pantry` library) Command line equivalent (takes precedence): [`--snapshot-location-base`](../global_flags.md#-snapshot-location-base-command-option) option Sets the base location of the LTS Haskell or Stackage Nightly snapshots. For example: ~~~yaml snapshot-location-base: https://example.com/snapshots/location/ ~~~ has the following effect: * `lts-X.Y` expands to `https://example.com/snapshots/location/lts/X/Y.yaml` * `nightly-YYYY-MM-DD` expands to `https://example.com/snapshots/location/nightly/YYYY/M/D.yaml` This key is convenient in setups that restrict access to GitHub, for instance closed corporate setups. In this setting, it is common for the development environment to have general access to the internet, but not for testing/building environments. To avoid the firewall, one can run a local snapshots mirror and then use a custom `snapshot-location-base` in the closed environments only. ## stack-colors Command line equivalent (takes precedence): `--stack-colors` option Stack uses styles to format some of its output. The default styles do not work well with every terminal theme. This option specifies Stack's output styles, allowing new styles to replace the defaults. The option is used as `stack-colors: `, where `` is a colon-delimited sequence of key=value, 'key' is a style name and 'value' is a semicolon-delimited list of 'ANSI' SGR (Select Graphic Rendition) control codes (in decimal). Use the command `stack ls stack-colors --basic` to see the current sequence. The 'ANSI' standards refer to (1) standard ECMA-48 'Control Functions for Coded Character Sets' (5th edition, 1991); (2) extensions in ITU-T Recommendation (previously CCITT Recommendation) T.416 (03/93) 'Information Technology – Open Document Architecture (ODA) and Interchange Format: Character Content Architectures' (also published as ISO/IEC International Standard 8613-6); and (3) further extensions used by 'XTerm', a terminal emulator for the X Window System. The 'ANSI' SGR codes are described in a [Wikipedia article](http://en.wikipedia.org/wiki/ANSI_escape_code) and those codes supported on current versions of Windows in [Microsoft's documentation](https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences). For example, users of the popular [Solarized Dark](https://ethanschoonover.com/solarized/) terminal theme might wish to set the styles as follows: ~~~yaml stack-colors: error=31:good=32:shell=35:dir=34:recommendation=32:target=95:module=35:package-component=95:secondary=92:highlight=32 ~~~ In respect of styles used in verbose output, some of that output occurs before the configuration file is processed. (The British English spelling (colour) is also accepted. In configuration files, the American spelling is the alternative that has priority.) ## stack-developer-mode [:octicons-tag-24: 2.3.3](https://github.com/commercialhaskell/stack/releases/tag/v2.3.3) Default (official distributed binaries): `false` Default (built from source): `true` Turns on a mode where some messages are printed at WARN level instead of DEBUG level, especially useful for developers of Stack itself. ~~~yaml stack-developer-mode: false ~~~ ## system-ghc Default: `false`, unless the [Docker](../../topics/docker_integration.md) or [Nix](../../topics/nix_integration.md) integration is enabled. Command line equivalent (takes precedence): `--[no-]system-ghc` flag Enables or disables using the GHC available on the PATH. (Make sure PATH is explicit, i.e., don't use ~.) Useful to enable if you want to save the time, bandwidth or storage space needed to setup an isolated GHC. In a Nix-enabled configuration, Stack is incompatible with `system-ghc: false`. ~~~yaml # Turn on system GHC system-ghc: true ~~~ ## templates Command line equivalent (takes precedence): `stack new --param :` (or `-p`) option Templates used with `stack new` have a number of parameters that affect the generated code. These can be set for all new projects you create. The result of them can be observed in the generated LICENSE and Cabal files. The value for all of these parameters must be strings. The parameters are: `author-email`, `author-name`, `category`, `copyright`, `year` and `github-username`. * _author-email_ - sets the `maintainer` property in Cabal * _author-name_ - sets the `author` property in Cabal and the name used in LICENSE * _category_ - sets the `category` property in Cabal. This is used in Hackage. For examples of categories see [Packages by category](https://hackage.haskell.org/packages/). It makes sense for `category` to be set on a per project basis because it is uncommon for all projects a user creates to belong to the same category. The category can be set per project by passing `-p "category:value"` to the `stack new` command. * _copyright_ - sets the `copyright` property in Cabal. It is typically the name of the holder of the copyright on the package and the year(s) from which copyright is claimed. For example: `Copyright (c) 2023-2025 Joe Bloggs` * _year_ - if `copyright` is not specified, `year` and `author-name` are used to generate the copyright property in Cabal. If `year` is not specified, it defaults to the current year. * _github-username_ - used to generate `homepage` and `source-repository` in Cabal. For instance `github-username: myusername` and `stack new my-project new-template` would result: ~~~yaml homepage: http://github.com/myusername/my-project#readme source-repository head type: git location: https://github.com/myusername/my-project ~~~ These properties can be set in `config.yaml` as follows: ~~~yaml templates: params: author-name: Your Name author-email: youremail@example.com category: Your Projects Category copyright: 'Copyright (c) 2025 Your Name' github-username: yourusername ~~~ Additionally, `stack new` can automatically initialize source control repositories in the directories it creates. Source control tools can be specified with the `scm-init` option. At the moment, only `git` is supported. ~~~yaml templates: scm-init: git ~~~ ## urls Default: ~~~yaml urls: latest-snapshot: https://stackage-haddock.haskell.org/snapshots.json ~~~ Customize the URLs where Stack looks for snapshot build plans. !!! note The default for Stack 1.3.0 to 2.15.3 was https://s3.amazonaws.com/haddock.stackage.org/snapshots.json. Following the handover of the Stackage project to the Haskell Foundation in early 2024, the file at that URL may not be up to date. Users of those versions of Stack should configure the URL to be the default above. ## with-gcc Command line equivalent (takes precedence): `--with-gcc` option Specify a path to GCC explicitly, rather than relying on the normal path resolution. ~~~yaml with-gcc: /usr/local/bin/gcc-5 ~~~ ## with-hpack Command line equivalent (takes precedence): `--with-hpack` option Use an [Hpack](https://github.com/sol/hpack) executable, rather than Stack's in-built version of the Hpack functionality. ~~~yaml with-hpack: /usr/local/bin/hpack ~~~ ## work-dir [:octicons-tag-24: 0.1.10.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.10.0) Default: `.stack-work` Command line equivalent (takes precedence): [`--work-dir`](../global_flags.md#-work-dir-option) option Environment variable alternative (lowest precedence): [`STACK_WORK`](../environment_variables.md#stack_work) `work-dir` specifies the path of Stack's work directory, within a local project or package directory. The path must be a relative one, relative to the root directory of the project or package. The relative path cannot include a `..` (parent directory) component. stack-3.7.1/doc/configure/yaml/project.md0000644000000000000000000003754215023557531016516 0ustar0000000000000000
# Project-specific configuration Project-specific configuration options are valid only in a project-level configuration file (`stack.yaml`, by default). Most of Stack's configuration options are [non-project specific](non-project.md). Each of the Haskell packages to which a Stack project relates is either a **project package** that is part of the project and located locally or a package on which one or more of the project packages depends (directly or indirectly). The latter is referred to as a **dependency** and it may be located locally or elsewhere. !!! info Project packages are built by default. Dependencies are only built when needed. Building can target individual components of a project package. The individual components of dependencies cannot be targeted. Test suite and benchmark components of a project package can be built and run. The library and executable components of a dependency, and only those components, are built when the dependency is needed. In your project-specific options, you specify both **which project packages** to build and **which dependencies to use** when building these packages. A dependency specified as an [extra-dep](#extra-deps) will shadow a package of the same name specified in a [snapshot](#snapshot). A project package will shadow a dependency of the same name. ## snapshot Command line equivalent (takes precedence): [`--snapshot`](../global_flags.md#-snapshot-option) or [`--resolver`](../global_flags.md#-resolver-option) option The `snapshot` key specifies which snapshot is to be used for this project. A snapshot defines a GHC version, the package version of packages available for installation, and various settings like build flags. It is also called a resolver since a snapshot states how dependencies are resolved. There are currently four snapshot types: * LTS Haskell snapshots, e.g. `snapshot: lts-23.24` * Stackage Nightly snapshots, e.g. `snapshot: nightly-2025-06-15` * No snapshot, just use packages shipped with the compiler. For GHC this looks like `snapshot: ghc-9.8.4` * Custom snapshot, via a URL or relative file path. For further information, see the [snapshot location](../../topics/snapshot_location.md) documentation. Each of these snapshots will also determine what constraints are placed on the compiler version. See the [compiler-check](non-project.md#compiler-check) option for some additional control over compiler version. A package version specified in a snapshot can be shadowed by an [extra-dep](#extra-deps) of the same name or a [project package](#packages) of the same name. ## resolver `resolver` and [`snapshot`](#snapshot) are synonyms. Only one of these keys is permitted, not both. ## packages Default: ~~~yaml packages: - . ~~~ The `packages` key specifies a list of the project packages that are part of your project. These are specified via paths to local directories. A path is considered relative to the directory containing the project-level configuration file (`stack.yaml`, by default). For example, if the `stack.yaml` file is located at `/dir1/dir2/stack.yaml`, and has: ~~~yaml packages: - my-package - dir3/my-other-package ~~~ the configuration means "project packages in directories `/dir1/dir2/my-package` and `/dir1/dir2/dir3/my-other-package`". The `packages` key is optional. The default value, '`.`', means that the project has a single project package located in the current directory. A project package will shaddow a dependency of the same name. A package version specified in a snapshot can be shadowed by an [extra-dep](#extra-deps) of the same name or a [project package](#packages) of the same name. Each specified project package directory must have a valid Cabal file or Hpack `package.yaml` file present. Any subdirectories of the directory are not searched for Cabal files. A subdirectory has to be specified as an independent item in the list of project packages. A project package is different from a dependency (located locally or elsewhere) specified as an [extra-dep](#extra-deps) or via a [snapshot](#snapshot). For example: * a project package will be built by default by commanding [`stack build`](../../commands/build_command.md) without specific targets. A dependency will only be built if it is needed; and * test suites and benchmarks may be built and run for a project package. They are never run for a dependency. ## extra-deps Default: `[]` The `extra-deps` key specifies a list of extra dependencies on top of what is defined in the [snapshot](#snapshot). A dependency may come from either a Pantry package location or a local file path. A Pantry package location is one or three different kinds of sources: * the package index (Hackage); * an archive (a tarball or zip file, either local or over HTTP or HTTPS); or * a Git or Mercurial repository. For further information on the format for specifying a Pantry package location, see the [package location](../../topics/package_location.md) documentation. For example: ~~~yaml extra-deps: # The latest revision of a package in the package index (Hackage): - acme-missiles-0.3 # A specific revision of a package in the package index (Hackage): - acme-missiles-0.3@rev:0 # An *.tar.gz archive file over HTTPS: - url: https://github.com/example-user/my-repo/archive/08c9b4cdf977d5bcd1baba046a007940c1940758.tar.gz subdirs: - my-package # A Git repository at a specific commit: - git: https://github.com/example-user/my-repo.git commit: '08c9b4cdf977d5bcd1baba046a007940c1940758' # An archive of files at a point in the history of a GitHub repository # (identified by a specific commit): - github: example-user/my-repo commit: '08c9b4cdf977d5bcd1baba046a007940c1940758' subdirs: - my-package ~~~ !!! note GHC boot packages are special. An extra-dep with the same package name and version as a GHC boot package will be ignored. !!! note The `commit:` key expects a YAML string. A commit hash, or partial hash, comprised only of digits represents a YAML number, unless it is enclosed in quotation marks. For a local file path source, the path is considered relative to the directory containing the `stack.yaml` file. For example, if the `stack.yaml` is located at `/dir1/dir2/stack.yaml`, and has: ~~~yaml extra-deps: - my-package - dir3/my-other-package ~~~ the configuration means "extra-deps packages in directories `/dir1/dir2/my-package` and `/dir1/dir2/dir3/my-other-package`". !!! note A local file path that has the format of a package identifier will be interpreted as a reference to a package on Hackage. Prefix it with `./` to avoid that confusion. !!! note A specified extra-dep that does not have the format of a valid Pantry package location (for example, a reference to a package on Hackage that omits the package's version) will be interpreted as a local file path. An extra-dep will shadow a dependency specified in a [snapshot](#snapshot) of the same name. An extra-dep can be shadowed by a [project package](#packages) of the same name. !!! info "GHC wired-in packages" Some Haskell packages published on Hackage, for example `base` and `ghc`, are referred to as 'wired-in' to one or more versions of GHC or as 'magic'. They can be distinguished from normal packages by the contents of their Cabal files: GHC's `-this-unit-id` option is set as the name of the package without a version. For example, the `base.cabal` for `base-4.19.1.0` includes: ~~~yaml -- We need to set the unit id to base (without a version number) -- as it's magic. ghc-options: -this-unit-id base ~~~ The GHC boot packages that are 'wired-in' cannot be shaddowed with different versions of the same package. Given their dependencies, the use of these boot packages in a build plan may limit what can be specified as an extra-dep. For example, GHC boot package `ghc-9.8.2` has a dependency on `process`. Its `*.conf` file identifies the dependency as `process-1.6.18.0-4fb7`. If package `ghc-9.8.2` is part of a build plan and a different version of `process` is specified as an extra-dep, during a build, Stack will identify that the build plan refers to two versions of `process` and warn that the build is likely to fail. Stack treats the following as the names of 'wired-in' packages: `base`, `dph-par`, `dph-seq`, `ghc-bignum`, `ghc-prim`, `ghc`, `integer-gmp`, `integer-simple`, `interactive`, `rts` and `template-haskell`. ## flags Default: `{}` Command line equivalent (takes precedence): [`stack build --flag`](../../commands/build_command.md#-flag-option) option Cabal flags can be set for each package separately. For example: ~~~yaml flags: package-name: flag-name: true ~~~ This overrides all Cabal flag specifications (if any) for the specified packages in the snapshot. !!! note For a package included directly in the snapshot, if the Cabal flag specifications differ from the Cabal flag specifications (if any) in the snapshot, then the package will automatically be promoted to be an [extra-dep](#extra-deps). !!! note In order to set a Cabal flag for a GHC boot package, the package must be specified as an [extra-dep](#extra-deps). ## drop-packages [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Default: `[]` Packages which, when present in the snapshot specified in the [`snapshot`](#snapshot) or [`resolver`](#resolver) key, should not be included in our project. This can be used for a few different purposes, e.g.: * Ensure that packages you don't want used in your project cannot be used in a `package.yaml` file (e.g., for license reasons) * When using a custom GHC build, avoid incompatible packages (see this [comment](https://github.com/commercialhaskell/stack/pull/4655#issuecomment-477954429)). ~~~yaml drop-packages: - buggy-package - package-with-unacceptable-license ~~~ !!! info Stackage snapshots LTS Haskell 14.27 (GHC 8.6.5) and earlier, and Nightly 2022-02-08 (GHC 8.8.2) and earlier, included directly the `Cabal` package. Later snapshots do not include directly that package (which is a GHC boot package). For the older Stackage snapshots, it could be handy to drop the snapshot-specified `Cabal` package, to avoid building that version of the package. For the later snapshots, there is no package version to drop. ## user-message If present, specifies a message to be displayed every time the configuration is loaded by Stack. It can serve as a reminder for the user to review the configuration and make any changes if needed. The user can delete this message if the generated configuration is acceptable. Consecutive line ends in the message are interpreted as a single blank line. For example, a user-message is inserted by `stack init` when it omits packages or adds external dependencies, namely: ~~~yaml user-message: | Warning (added by new or init): Some packages were found to be incompatible with the snapshot and have been left commented out in the packages section. Warning (added by new or init): Specified snapshot could not satisfy all dependencies. Some external packages have been added as dependencies. You can omit this message by removing it from the project-level configuration file. ~~~ ## custom-preprocessor-extensions Default: `[]` Command line equivalent: `--customer-preprocessor-extensions` option In order for Stack to be aware of any custom preprocessors you are using, add their extensions here ~~~yaml custom-preprocessor-extensions: - erb ~~~ ??? example "Use of a custom preprocessor" The [Ruby](https://www.ruby-lang.org/en/) programming language provides [`erb`](https://docs.ruby-lang.org/en/master/ERB.html) at the command line. `erb` provides a templating system for Ruby. The following example uses `erb` as a custom preprocessor. The example is a single-package project with a customised `Setup.hs`, which Stack will use to build: ~~~haskell {-# LANGUAGE CPP #-} module Main ( main ) where import Distribution.Simple ( defaultMainWithHooks, simpleUserHooks ) import Distribution.Simple.PreProcess ( PreProcessor (..), mkSimplePreProcessor, unsorted ) import Distribution.Simple.UserHooks ( UserHooks (..) ) import Distribution.Types.BuildInfo ( BuildInfo ) import Distribution.Types.ComponentLocalBuildInfo ( ComponentLocalBuildInfo ) import Distribution.Types.LocalBuildInfo ( LocalBuildInfo ) import System.Process ( readCreateProcess, proc, shell ) main :: IO () main = defaultMainWithHooks simpleUserHooks { hookedPreProcessors = [("erb", runRuby)] } runRuby :: BuildInfo -> LocalBuildInfo -> ComponentLocalBuildInfo -> PreProcessor runRuby _ _ _ = PreProcessor { platformIndependent = True , ppOrdering = unsorted , runPreProcessor = mkSimplePreProcessor $ \erbFile fout verbosity -> readCreateProcess (erbProcess erbFile) "" >>= writeFile fout } where erbProcess erbFile = #if defined(mingw32_HOST_OS) shell $ "erb " <> erbFile #else proc "erb" [erbFile] #endif ~~~ The example has a package description file (`package.yaml`) that specifies a `Custom` build type: ~~~yaml spec-version: 0.36.0 name: my-package version: 0.1.0.0 build-type: Custom dependencies: base custom-setup: dependencies: - base - Cabal - process library: source-dirs: src generated-exposed-modules: MyModule ~~~ The example has a `src/MyModule.erb` file that will be preprocessed to create Haskell source code: ~~~text module MyModule where <% (1..5).each do |i| %> test<%= i %> :: Int test<%= i %> = <%= i %> <% end %> ~~~ The example has a project-level configuration file (`stack.yaml`): ~~~yaml snapshot: lts-22.30 custom-preprocessor-extensions: - erb ~~~ ## extra-package-dbs [:octicons-tag-24: 0.1.6.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.6.0) Default: `[]` A list of relative or absolute paths to package databases. These databases will be added on top of GHC's global package database before the addition of other package databases. !!! warning Use of this feature may result in builds that are not reproducible, as Stack has no control over the contents of the extra package databases. ## curator :octicons-beaker-24: Experimental [:octicons-tag-24: 2.1.0.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.0.1) Default: `{}` Configuration intended for use only by the [`curator` tool](https://github.com/commercialhaskell/curator), which uses Stack to build packages. For given package names (which need not exist in the project), Stack can be configured to ignore (skip) silently building test suites, building benchmarks and/or creating Haddock documentation or to expect that building test suites, building benchmarks and/or creating Haddock documentation will fail. For example: ~~~yaml curator: skip-test: - my-package1 expect-test-failure: - my-package2 skip-bench: - my-package3 expect-benchmark-failure: - my-package4 skip-haddock: - my-package5 expect-haddock-failure: - my-package6 ~~~ stack-3.7.1/doc/CONTRIBUTING.md0000644000000000000000000010453715030022205014012 0ustar0000000000000000# Contributors Guide Thank you for considering contributing to the maintenance or development of Stack, or otherwise supporting users of Stack! We hope that the following information will encourage and assist you. We start with some advice about Stack's goals and governance, and approach to supporting users. ## Stack's goals Stack's current goals are: * To provide easy to use tooling for Haskell development * To provide complete support for at least the following three development environments: Linux, macOS, and Windows * To address the needs of industrial users, open source maintainers, and other people * To focus on the 'curated package set' use case * To prioritize reproducible build plans The goals above are not set in stone. However, any major changes to them should involve significant public discussion and a public vote by the Stack maintainer team. ## Stack's governance People involved in maintaining or developing Stack with rights to make commits to the repository can be classified into two groups: 'committers' and 'maintainers'. ### Stack's committers We encourages a wide range of people to be granted rights to make commits to the repository. People are encouraged to take initiative to make non-controversial changes, such as documentation improvements, bug fixes, performance improvements, and feature enhancements. Maintainers should be included in discussions of controversial changes and tricky code changes. Our general approach is **"it's easier to ask forgiveness than permission"**. If there is ever a bad change, it can always be rolled back. ### Stack's maintainers Stack's maintainers are long-term contributors to the project. Michael Snoyman (@snoyberg) was the founder of Stack, and its initial maintainer - and he has added others. Michael's current interests and priorities mean that he is no longer actively involved in adding new features to Stack. Maintainers are recognized for their contributions including: * Direct code contribution * Review of pull requests * Interactions on the GitHub issue tracker * Documentation management * External support - for example, hosting or training The maintainer team make certain decisions when that is necessary, specifically: * How to proceed, if there is disagreement on how to do so on a specific topic * Whether to add or remove (see further below) a maintainer Generally, maintainers are only removed due to non-participation or actions unhealthy to the project. Removal due to non-participation is not a punishment, simply a recognition that maintainership is for active participants only. We hope that removal due to unhealthy actions will never be necessary, but would include protection for cases of: * Disruptive behavior in public channels related to Stack * Impairing the codebase through bad commits/merges Like committers, maintainers are broadly encouraged to make autonomous decisions. Each maintainer is empowered to make a unilateral decision. However, maintainers should favor getting consensus first if: * They are uncertain what is the best course of action * They anticipate that other maintainers or users of Stack will disagree on the decision ## Stack's support A large part of the general discussion around Stack is on support-related topics, and that is reflected in the current issue tracker content. Assistance in responding to such matters is greatly appreciated. While support-related matters can be posted here as an 'issue', we encourage the use of other forums, in particular the [Haskell Community](https://discourse.haskell.org/) forum. See its 'Learn' category. We also recommend that forum for general discussions about Stack's current or desired features. Stack is also discussed: * in the Haskell [Stack and Stackage](https://matrix.to/#/#haskell-stack:matrix.org) room (address `#haskell-stack:matrix.org`) on [Matrix](https://matrix.org/); and * on Reddit's [Haskell community](https://www.reddit.com/r/haskell/). We encourage use of those other forums because support-related discussions can clog up the issue tracker and make it more difficult to maintain the project. People needing support may also get a faster and fuller response on other forums. Additions to the issue tracker are better suited to concrete feature proposals, bug reports, and other code base discussions (for example, refactorings). ## Bug Reports Please [open an issue](https://github.com/commercialhaskell/stack/issues/new) and use the provided template to include all necessary details. The more detailed your report, the faster it can be resolved and will ensure it is resolved in the right way. Once your bug has been resolved, the responsible person will tag the issue as _Needs confirmation_ and assign the issue back to you. Once you have tested and confirmed that the issue is resolved, close the issue. If you are not a member of the project, you will be asked for confirmation and we will close it. ## Documentation Consistent with its goal of being easy to use, Stack aims to maintain a high quality of in-tool and online documentation. The in-tool documentation includes the output when the `--help` flag is specified and the content of Stack's warning and error messages. When drafting documentation it is helpful to have in mind the intended reader and what they are assumed to know, and not know, already. In that regard, documentation should aim to meet, at least, the needs of a person who is about to begin to study computing as an undergraduate but who has not previously coded using Haskell. That person may be familiar with one popular operating system but may not be familiar with others. The files which make up Stack's online documentation are located in the `doc` directory of the repository. They are formatted in the [Markdown syntax](https://daringfireball.net/projects/markdown/), with some extensions. Those files are rendered on [haskellstack.org](http://haskellstack.org) by [Read the Docs](https://readthedocs.org/) using [MkDocs](https://www.mkdocs.org/) and the [Material for MkDocs](https://squidfunk.github.io/mkdocs-material/) theme. The `stable` branch of the repository provides the 'stable' version of the online documentation. The `master` branch provides the 'latest' version of the documentation. The 'stable' version of the online documentation is intended to be applicable to the latest released version of Stack. If you would like to help with that documentation, please submit a [pull request](https://help.github.com/articles/using-pull-requests/) with your changes/additions based off the [stable branch](https://github.com/commercialhaskell/stack/tree/stable). The Markdown files are organised into the navigation menu (the table of contents) in the file `mkdocs.yml`, the configuration file for MkDocs. The description of a file in the menu can differ from the file's name. The navigation menu allows files to be organised in a hierarchy. Currently, up to three levels are used. The top level is: * **Welcome!:** The introduction to Stack. This page aims to be no longer than necessary but also to not assume much existing knowledge on the part of the reader. It provides a 'quick start' guide to getting and using Stack. * **How to get & use Stack:** This includes Stack's user's guide, answers to frequently asked questions, and more thorough explanations of aspects of Stack. The user's guide is divided into two parts. The first part is 'introductory', and has the style of a tutorial. The second part is 'advanced', and has more of a reference style. * **How Stack works (advanced):** Many users will not need to consult this advanced documentation. * **Stack's code (advanced):** Other information useful to people contributing to, or maintaining, Stack's code, documentation, and other files. * **Signing key:** How Stack's released executables are signed. * **Glossary:** A glossary of terms used throughout Stack's in-tool and online documentation. We aim to describe the same things in the same way in different places. * **Version history:** The log of changes to Stack between versions. The specific versions of the online documentation (eg `v: v2.9.1`) are generated from the content of files at the point in the repository's history specified by the corresponding release tag. Consequently, that content is fixed once released. If the names of Markdown files do not change between versions, then people can use the flyout on the online documentation to move between different versions of the same page. For that reason, the names of new Markdown files should be chosen with care and existing Markdown files should not be deleted or renamed without due consideration of the consequences. The Markdown syntax supported by MkDocs and the Material for MkDocs theme can differ from the GitHub Flavored Markdown ([GFM](https://github.github.com/gfm/)) supported for content on GitHub.com. Please refer to the [MkDocs documentation](https://www.mkdocs.org/user-guide/writing-your-docs/#writing-with-markdown) and the [Material for MkDocs reference](https://squidfunk.github.io/mkdocs-material/reference/) to ensure your pull request will achieve the desired rendering. The extensions to the basic Markdown syntax used are set out in `mkdocs.yml` and include: * admonitions * code blocks, with syntax highlighting provided by [Pygments](https://pygments.org/) * content tabs, which can be nested * icons and emojis The files in the `doc` directory of the repository include two symbolic links (symlinks), `ChangeLog.md` and `CONTRIBUTING.md`. Users of Git on Windows should be aware of its approach to symbolic links. See the [Git for Windows Wiki](https://github.com/git-for-windows/git/wiki/Symbolic-Links). If `git config --show-scope --show-origin core.symlinks` is `false` in a local repository on Windows, then the files will be checked out as small plain files that contain the link text See the [Git documentation](https://git-scm.com/docs/git-config#Documentation/git-config.txt-coresymlinks). The online documentation can be previewed using the `mkdocs` tool, as described in [Getting Started with MkDocs](https://www.mkdocs.org/getting-started/). The prerequisites are: * [Python](https://www.python.org/); and * the required Python packages set out in `doc/requirements.txt`. They can be installed using Python's package manager `pip` with: ~~~text pip install --requirement doc/requirements.txt ~~~ Once the required version of `mkdocs` is installed, command `mkdocs serve` in the same directory as the `mkdocs.yml` file to start a web server. The command will, eventually, output the URL at which the documentation is being served. Command `mkdocs build` to build the documentation. === "Windows" With the correct prerequisites (see further below), users of the `make` tool in the Stack-supplied MSYS2 environment can automate some of these steps from Stack's project directory with: * preview: `stack exec -- make docs-serve`; and * build: `stack exec -- make _site/index.html`. However, Windows and the Stack-supplied MSYS2 environment do not come with Python or `make` by default. Further, Python on Windows does not use the `python3` command (used on Unix-like operating systems) to invoke Python. Further still, in the MSYS2 environment, development versions of packages `libxml2` and `libxslt` are necessary dependencies. Consequently, the automation requires the following command to install requirements into the the MSYS2 environment: ~~~text stack exec -- pacman --sync python make libxml2-devel libxslt-devel ~~~ !!! note If the automation fails before the `mkdocs` tool etc is installed, the directory `.python-doc-virtualenv` created by the automation will need to be deleted before the automation will work again. For most users, the automation will be less convenient than simply using the `mkdocs serve` command directly. === "Unix-like" With `python3` and `make` available on the PATH, users of the `make` tool can automate some of these steps from Stack's project directory with: * preview: `make docs-serve`; and * build: `make _site/index.html`. ## Error messages Stack catches exceptions thrown by its dependencies or by Stack itself in `Stack.main`. In addition to exceptions that halt Stack's execution, Stack logs certain other matters as 'errors'. To support the Haskell Foundation's [Haskell Error Index](https://errors.haskell.org/) initiative, all Stack error messages generated by Stack itself should have a unique initial line: ~~~text Error: [S-nnnn] ~~~ where `nnnn` is a four-digit number in the range 1000 to 9999. If you create a new Stack error, select a number using a random number generator (see, for example, [RANDOM.ORG](https://www.random.org/)) and check that number is not already in use in Stack's code. If it is, pick another until the number is unique. All exceptions generated by Stack itself are implemented using data constructors of closed sum types. Typically, there is one such type for each module that exports functions that throw exceptions. This type and the related `instance` definitions are usually located at the top of the relevant module. Stack supports two types of exceptions: 'pretty' exceptions that are instances of class `RIO.PrettyPrint.Pretty`, which provides `pretty :: e -> StyleDoc`, and thrown as expressions of type `RIO.PrettyPrint.PrettyException.PrettyException`; and other 'plain' exceptions that are simply instances of class `Control.Exception.Exception` and, hence, instances of class `Show`. These types and classes are re-exported by `Stack.Prelude`. Stack throws exceptions in parts of the code that should, in principle, be unreachable. The functions `Stack.Prelude.bugReport` and `Stack.Prelude.bugPrettyReport` are used to give the messages a consistent format. The names of the data constructors for those exceptions usually end in `Bug`. In a few cases, Stack may throw an exception in 'pure' code. The function `RIO.impureThrow :: Exception e => e -> a`, re-exported by `Stack.Prelude`, is used for that purpose. ## Code If you would like to contribute code to fix a bug, add a new feature, or otherwise improve `stack`, pull requests are most welcome. It's a good idea to [submit an issue](https://github.com/commercialhaskell/stack/issues/new) to discuss the change before plowing into writing code. If you'd like to help out but aren't sure what to work on, look for issues with the [awaiting pull request](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3A%22awaiting+pull+request%22) label. Issues that are suitable for newcomers to the codebase have the [newcomer friendly](https://github.com/commercialhaskell/stack/issues?q=is%3Aopen+is%3Aissue+label%3A%22awaiting+pull+request%22+label%3a%22newcomer+friendly%22) label. Best to post a comment to the issue before you start work, in case anyone has already started. Please include a [ChangeLog](https://github.com/commercialhaskell/stack/blob/master/ChangeLog.md) entry and [documentation](https://github.com/commercialhaskell/stack/tree/master/doc/) updates with your pull request. ## Backwards Compatibility The Stack package provides a library and an executable (`stack`) that depends on the library. The library is intended for use only by the executable. Consequently, the Stack package does not need to, and does not, strive for the compatibility with a range of versions of GHC that a library package (such as `pantry`) would seek. Stack aims to depend on well-known packages. The specific versions on which it depends at any time are specified by `package.yaml` and `stack.yaml`. It does not aim to be compatible with more than one version of the `Cabal` package at any time. At the time of writing (June 2025) the package versions are primarily ones in Stackage snapshot LTS Haskell 23.24 (for GHC 9.8.4) and `hpack-0.38.1`, `persistent-2.17.0.0` and `tls-2.1.8`. A Stack executable makes use of Cabal (the library) through a small 'Setup' executable that it compiles from Haskell source code. The executable compiles that code with a dependency on the version of Cabal that ships with the specified GHC compiler. Each release of Stack will normally aim to support all versions of GHC and the Cabal package in Stackage LTS Haskell snapshots published within seven years of the release. For example, snapshot LTS Haskell 12.0, published on 9 July 2018, was the first LTS Haskell snapshot to provide GHC 8.4.3 which comes with `base-4.11.1.0` and `Cabal-2.2.0.1`. Normally, until, at least, 9 July 2025, Stack releases would aim to support the immediate predecessor, GHC 8.2.2 and `base-4.10.1.0`, `Cabal-2.0.1.1` and Haddock 2.18.1. However, Stack 3.1.1 dropped support for versions of Cabal before 2.2. `Cabal-2.2.0.0` was released with GHC 8.4.1 on 8 March 2018. When a version of the Stack executable actually ceases to support a version of GHC and `Cabal`, that should be recorded in Stack's [ChangeLog](https://github.com/commercialhaskell/stack/blob/master/ChangeLog.md). ## Code Quality The Stack project uses [yamllint](https://github.com/adrienverge/yamllint) as a YAML file quality tool and [HLint](https://github.com/ndmitchell/hlint) as a code quality tool. ### Linting of YAML files The yamllint configuration extends the tools default and is set out in `.yamllint.yaml`. In particular, indentation is set at 2 spaces and `- ` in sequences is treated as part of the indentation. ### Linting of Haskell source code The HLint configurations is set out in `.hlint.yaml`. Stack contributors need not follow dogmatically the suggested HLint hints but are encouraged to debate their usefulness. If you find a HLint hint is not useful and detracts from readability of code, consider marking it in the [configuration file](https://github.com/commercialhaskell/stack/blob/master/.hlint.yaml) to be ignored. Please refer to the [HLint manual](https://github.com/ndmitchell/hlint#readme) for configuration syntax. Quoting [@mgsloan](https://github.com/commercialhaskell/stack/pulls?utf8=%E2%9C%93&q=is%3Apr%20author%3Amgsloan): > We are optimizing for code clarity, not code concision or what HLint thinks. You can install HLint with Stack. You might want to install it in the global project in case you run into dependency conflicts. HLint can report hints in your favourite text editor. Refer to the HLint repository for more details. To install, command: ~~~text stack install hlint ~~~ Once installed, you can check your changes with command: ~~~text stack exec -- sh ./etc/scripts/hlint.sh ~~~ ## Code syntax Stack makes use of GHC's `GHC2021` collection of language extensions, which is set using the `language` key in the `package.yaml` file. Stack makes use of single-constructor types where the constructor has a large number of fields. Some of those fields have similar types, and so on. Given that, Stack makes use of `OverloadedRecordDot`, introduced in GHC 9.2.1. It also makes use of `NoFieldSelectors`, also introduced in GHC 9.2.1, and, where necessary, `DuplicateRecordFields`. Together, these language extensions enable the removal from the names of fields of the prefixes that were used historically to indicate the type and make field names unique. This is because the names of fields no longer need to be unique in situations where the intended field is unambiguous. This allows for a terser syntax without loss of expressiveness. For example: ~~~haskell let cliTargets = (boptsCLITargets . bcoBuildOptsCLI) bco ~~~ can become: ~~~haskell let cliTargets = bco.buildOptsCLI.targets ~~~ The intended field is unambiguous in almost all cases. In the case of a few record updates it is ambiguous. The name of the field needs to be qualified in those cases. For example: ~~~haskell import qualified Stack.Types.Build as ConfigCache ( ConfigCache (..) ) ... let ignoreComponents :: ConfigCache -> ConfigCache ignoreComponents cc = cc { ConfigCache.components = Set.empty } ~~~ ## Code Style A single code style is not applied consistently to Stack's code and Stack is not Procrustean about matters of style. Rules of thumb, however, are: * keep pull requests that simply reformat code separate from those that make other changes to code; and * when making changes to code other than reformatting, follow the existing style of the function(s) or module(s) in question. That said, the following may help: * Stack's code generally avoids the use of C preprocessor (CPP) directives. Windows and non-Windows code is separated in separate source code directories and distinguished in Stack's Cabal file. `Stack.Constants.osIsWindows :: Bool` is provided. Multi-line strings are generally formatted on the assumption that GHC's `CPP` language pragma is not being used. * Language pragmas usually start with `NoImplictPrelude`, where applicable, and then all others are listed alphabetically. The closing `#-}` are aligned, for purely aesthetic reasons. * Stack is compiled with GHC's `-Wall` enabled, which includes `-Wtabs` (no tabs in source code). Most modules are based on two spaces (with one space for a `where`) for indentation but older and larger modules are still based on four spaces. * Stack's code and documentation tends to be based on lines of no more than 80 characters or, if longer, no longer than necessary. * Stack uses export lists. * Stack's imports are listed alphabetically, including `Stack.Prelude`, where applicable. The module names are left aligned, with space left for `qualified` where it is absent. * Stack's code is sufficiently stable that explicit import lists can sensibly be used. The exception is the import of `Stack.Prelude`. Not all modules have comprehensive explicit import lists. * Short explicit import lists follow the module name. Longer lists start on the line below the module name. Spaces are used to separate listed items from their enclosing parentheses. * As noted above, the types used to implement Stack's exceptions and the related `instance` definitions are usually located at the top of the relevant module. * In function type signatures, the `::` is kept on the same line as the function's name. This format is Haskell syntax highlighter-friendly. * If `where` is used, the declarations follow on a separate line. ## Testing The Stack code has both unit tests and integration tests. ### Working with Unit Tests Unit tests can be found in the [tests/unit](https://github.com/commercialhaskell/stack/tree/master/tests/unit) directory. Tests are written using the [Hspec](https://hspec.github.io/) framework. In order to run the full test suite, you can simply command: ~~~text stack test ~~~ The `--file-watch` is a very useful option to get quick feedback. However, running the entire test suite after each file change will slow you down. You'll need to specify which test suite (unit test or integration) and pass arguments to specify which module you'd specifically like to run to get quick feedback. A description of this follows below. If you would like to run the unit tests on their own, you can command: ~~~text stack test stack:stack-unit-test ~~~ Running an individual module works with a command like this: ~~~text stack test stack:stack-unit-test --ta "-m " ~~~ Where `` is the name of the module without `Spec.hs`. You may also load tests into GHCi and run them with these command: ~~~text stack ghci stack:stack-unit-test --only-main # GHCi starting up output ... > :main -m "" ~~~ Where again, `` is the name of the module without `Spec.hs`. ### Working with Integration Tests Integration tests can be found in the [tests/integration](https://github.com/commercialhaskell/stack/tree/master/tests/integration) folder. Running the integration tests is a little involved, you'll need to command: ~~~text stack build --flag stack:integration-tests stack --exec stack-integration-test ~~~ Running an individual module works with a command like this: ~~~text stack build --flag stack:integration-tests stack --exec "stack-integration-test -m " ~~~ Where `` is the name of the folder listed in the [test/integration/tests/](https://github.com/commercialhaskell/stack/tree/master/test/integration/tests) directory. You may also achieve this through GHCi with this command: ~~~text stack ghci stack:stack-integration-test # GHCi starting up output ... > :main -m "" ~~~ Where again, `` is the name of the folder listed in the [test/integration/tests/](https://github.com/commercialhaskell/stack/tree/master/test/integration/tests) directory. You can disable a few integration tests through the -n option : ~~~text stack build --flag stack:integration-tests stack --exec "stack-integration-test -n -n " ~~~ To disable folders named after `` and `` It's especially useful when some tests are taking a while to complete. On Linux, the `stack-integration-test` executable uses the `lld` linker and expects it to be on the PATH. The integration tests complete significantly quicker with `lld` than with the `ld.bfd` linker. ## Continuous integration (CI) We use [GitHub Actions](https://docs.github.com/en/actions) to do CI on Stack. The configuration of the workflows is in the YAML files in `.github/workflows`. The current active workflows are: ### Linting - `lint.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**` The workflow has one job (`style`). It runs on `ubuntu` only and applies yamllint and Hlint. ### Test suite - `unit-tests.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**`. * requested The workflow has two jobs: `pedantic` and `unit-tests`. The `pedantic` job runs on `ubuntu` only and builds Stack with the `--pedantic` flag. The `unit-tests` job runs on a matrix of operating systems and Stack project-level configuration files (`stack.yaml`, by default). It builds and tests Stack with the following flags: `--haddock --no-haddock-deps`. Its approach to creating a cache depends on the operating system. Its 'Cache dependencies on Unix-like OS' step caches the Stack root on Unix-like operating systems. Its 'Cache dependencies on Windows' step caches the same information on Windows, but takes into account that a relevant directory is located outside of the Stack root. ### Integration-based - `integration-tests.yml` This workflow will run if: * there is a pull request * commits are pushed to these branches: `master`, `stable` and `rc/**` * any tag is created * requested The workflow has three jobs: `integration-tests`, `linux-arm64` and `github-release`. The `integration-tests` job runs on a matrix of operating systems (`ubuntu`, `windows` and `macos`) and makes use of the `release.hs` script at `etc/scripts`. Its approach to creating a cache is the same as for `unit-tests.yml`, described above. Its 'Install deps and run checks' step uses `release.hs check`. Its 'Build bindist' step uses `release.hs build`. Its 'Upload bindist' step uploads artifacts using the name of the runner's operating system (`Linux`, `Windows` or `macOS`) as the name for the artifacts. The `linux-arm64` job runs on a self-hosted runner for Linux and ARM64. It makes use of Docker and a Docker file at `etc/dockerfiles/arm64.Dockerfile`. Its 'Build bindist' step makes use of a compiled version of `release.hs` script at `etc/scripts` to command `release build`. Its 'Upload bindist' step uploads artifacts using `Linux-ARM64` as the name for the artifacts. The `github-release` job needs `integration-tests` and `linux-arm64`. It only takes effect if the trigger for the workflow was the creation of a tag. Its four steps `Download Linux/Windows/macOS/Linux-ARM64 artifact` download the named artifacts to path `_release`. Its step 'Hash and sign assets' makes use of a 'secret' environment variable `RELEASE_SIGNING_KEY` established by the owner of the Stack repository. The variable contains the private key for the GPG key with ID 0x575159689BEFB442. That key is imported into GPG and then used by GPG to create a detached signature for each file. ### Stan tool - `stan.yml` [Stan](https://hackage.haskell.org/package/stan) is a Haskell static analysis tool. As of `stan-0.1.0.1`, it supports GHC >= 9.6.3 and Stack is built with GHC 9.8.4. The tool is configured by the contents of the `.stan.toml` file. This workflow will run if: * there is a pull request * requested ## Haskell Language Server You may be using [Visual Studio Code](https://code.visualstudio.com/) (VS Code) with its [Haskell extension](https://marketplace.visualstudio.com/items?itemName=haskell.haskell), which is powered by the [Haskell Language Server](https://github.com/haskell/haskell-language-server) (HLS). Stack can be built with Stack (which is recommended) or with Cabal (the tool). === "Stack" If you use Stack to build Stack, command `stack ghci` in the root directory of the Stack project should work as expected, if you have first commanded `stack build` once. `stack build` causes Cabal (the library) to create the automatically generated module `Stack_build`. If `ghc` is not on your PATH, then Haskell Language Server may report the following error about `Stack.Constants.ghcShowOptionsOutput`: ~~~text • Exception when trying to run compile-time code: ghc: readCreateProcess: does not exist (No such file or directory) Code: (TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) • In the untyped splice: $(TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) ~~~ `ghc` should be on the PATH if you run VS Code itself in the Stack environment: ~~~text stack exec -- code . ~~~ The following [cradle (`hie.yaml`)](https://github.com/haskell/hie-bios) should suffice to configure Haskell Language Server (HLS) explicitly for `./Setup.hs` and each of the buildable components in Stack's Cabal file: ~~~yaml cradle: multi: - path: "./Setup.hs" config: cradle: direct: arguments: [] - path: "./" config: cradle: stack: - path: "./src" component: "stack:lib" - path: "./app" component: "stack:exe:stack" - path: "./tests/integration" component: "stack:exe:stack-integration-test" - path: "./tests/unit" component: "stack:test:stack-unit-test" ~~~ === "Cabal (the tool)" If you use Cabal (the tool) to build Stack, command `cabal repl` in the root directory of the Stack project should work as expected, if you have GHC and (on Windows) MSYS2 on the PATH. Stack's custom `./Setup.hs` causes `cabal repl` to cause Cabal (the library) to create the automatically generated module `Stack_build`. If `ghc` is not on your PATH, then Haskell Language Server may report the following error about `Stack.Constants.ghcShowOptionsOutput`: ~~~text • Exception when trying to run compile-time code: ghc: readCreateProcess: does not exist (No such file or directory) Code: (TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) • In the untyped splice: $(TH.runIO (readProcess "ghc" ["--show-options"] "") >>= TH.lift . lines) ~~~ `ghc` and (on Windows) MSYS2 should be on the PATH if you run commands (including `cabal`) in the Stack environment: ~~~text stack exec --no-ghc-package-path -- cabal repl ~~~ or ~~~text stack exec --no-ghc-package-path -- code . ~~~ Use of GHC's environment variable `GHC_PACKAGE_PATH` is not compatible with Cabal (the tool). That is why the `--no-ghc-package-path` flag must be specified with `stack exec` when relying on Cabal (the tool). The following [cradle (`hie.yaml`)](https://github.com/haskell/hie-bios) should suffice to configure Haskell Language Server (HLS) explicitly for `./Setup.hs` and each of the buildable components in Stack's Cabal file: ~~~yaml cradle: multi: - path: "./Setup.hs" config: cradle: direct: arguments: [] - path: "./" config: cradle: cabal: - path: "./src" component: "lib:stack" - path: "./app" component: "exe:stack" - path: "./tests/integration" component: "exe:stack-integration-test" - path: "./tests/unit" component: "test:stack-unit-test" ~~~ A cradle is not committed to Stack's repository because it imposes a choice of tool used for building. ## Dev Containers A [Development Container](https://containers.dev) (or Dev Container for short) allows you to use a container as a full‑featured development environment. You can run Dev Containers locally/remotely (with VS Code), or create a [Codespace](https://github.com/features/codespaces) for a branch in a repository to develop online. Stack's default Dev Container is intended for use with its default project‑level configuration (`stack.yaml`). But there are also Dev Containers for the experimental project‑level configurations. For further information, see the documentation for [Dev Containers](dev_containers.md). ## Slack channel If you're making deep changes and real-time communication with the Stack team would be helpful, we have a `#stack-collaborators` Slack channel in the Haskell Foundation workspace. To join the workspace, follow this [link](https://haskell-foundation.slack.com/join/shared_invite/zt-z45o9x38-8L55P27r12YO0YeEufcO2w#/shared-invite/email). ## Matrix room There is also a [Haskell Stack room](https://matrix.to/#/#haskell-stack:matrix.org) at address `#haskell-stack:matrix.org` on [Matrix](https://matrix.org/). stack-3.7.1/doc/dev_containers.md0000644000000000000000000001503614651506553015126 0ustar0000000000000000
# Dev Containers A *container* refers to an isolated area of memory where application software and some drivers execute. A [Development Container](https://containers.dev) (or Dev Container for short) allows a container to be used as a full‑featured development environment. Stack provides the following Dev Containers: * a default Dev Container, intended for use with Stack's default project‑level configuration file (`stack.yaml`); and * alternative Dev Containers, intended for use with Stack's experimental project‑level configurations (in anticipation of building Stack with more recent versions of GHC). Stack's Dev Containers provide the following tools: 1. The [Haskell Toolchain](https://www.haskell.org/ghcup/install/#supported-tools) ([GHC](https://www.haskell.org/ghc), Stack, [Cabal (the tool)](https://cabal.readthedocs.io) and [HLS](https://haskell-language-server.readthedocs.io)) 2. [Git](https://git-scm.com) 3. [HLint](https://hackage.haskell.org/package/hlint) 4. [yamllint](https://yamllint.readthedocs.io) 5. [ShellCheck](https://www.shellcheck.net) 6. [hadolint](https://github.com/hadolint/hadolint) The tools in the Haskell Toolchain are installed at `/usr/local/bin`. HLS is provided in the default Dev Container only. !!! info The PATH is `$HOME/.cabal/bin:$HOME/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin`. Consequently, executables installed with Cabal (the tool) (at `$HOME/.cabal/bin` or `$HOME/.local/bin`) or Stack or Pip (at `$HOME/.local/bin`) take precedence over the same executable installed at `/usr/local/sbin`, `/usr/local/bin`, etc. [VS Code](https://code.visualstudio.com) is used as IDE, with the following extensions pre‑installed: * [Haskell](https://marketplace.visualstudio.com/items?itemName=haskell.haskell) (Default Dev Container only) * [GitHub Pull Requests and Issues](https://marketplace.visualstudio.com/items?itemName=GitHub.vscode-pull-request-github) * [GitLens — Git supercharged](https://marketplace.visualstudio.com/items?itemName=eamodio.gitlens) * Pinned to version 11.7.0 due to unsolicited AI content in recent versions * [Git Graph](https://marketplace.visualstudio.com/items?itemName=mhutchie.git-graph) * [ShellCheck](https://marketplace.visualstudio.com/items?itemName=timonwong.shellcheck) * [hadolint](https://marketplace.visualstudio.com/items?itemName=exiasr.hadolint) * [Resource Monitor](https://marketplace.visualstudio.com/items?itemName=mutantdino.resourcemonitor) ## Parent images Stack's Dev Containers are derived from Docker images that are used to build the *statically linked* Linux/x86_64 and Linux/AArch64 binary distributions of Stack. These Docker images are multi‑architecture (`linux/amd64`, `linux/arm64/v8`) *GHC musl* images. They are based on Alpine Linux (that is [musl libc](https://musl.libc.org) and [BusyBox](https://www.busybox.net)). The images contain *unofficial* binary distributions of GHC (that is, ones not released by the GHC developers). That is because: 1. the official GHC binary distributions for Alpine Linux/x86_64 have known bugs; and 2. there are no official binary distributions for Alpine Linux/AArch64. Stack's global configuration (`/etc/stack/config.yaml`) sets `system-ghc: true` and `install-ghc: false`. That ensures that only the GHC available in the Dev Containers is used. ## Usage You can run Dev Containers locally/remotely with VS Code, or create a [GitHub Codespace](https://github.com/features/codespaces) for a branch in a repository to develop online. === "VS Code" Follow the instructions at [Developing inside a Container](https://code.visualstudio.com/docs/devcontainers/containers). === "GitHub Codespaces" For use with GitHub Codespaces, follow the instructions at [Creating a codespace for a repository](https://docs.github.com/en/codespaces/developing-in-codespaces/creating-a-codespace-for-a-repository#creating-a-codespace-for-a-repository). ## Build Stack Stack can be built with Stack (which is recommended) or with Cabal (the tool). === "Stack" Command `stack build` to build the `stack` executable. Append `--flag=stack:static` to build a *statically linked* `stack` executable that can run on any Linux machine of the same architecture. Append `--stack-yaml stack-ghc-$GHC_VERSION.yaml` if you want to use an experimental project‑level configuration with the appropriate Dev Container. === "Cabal (the tool)" !!! info Default Dev Container only. Command `cabal build` to build the `stack` executable. Append `--flag=static` to build a *statically linked* `stack` executable that can run on any Linux machine of the same architecture. ## Haskell Language Server (HLS) The [Haskell Language Server](https://github.com/haskell/haskell-language-server) and the [Haskell extension](https://marketplace.visualstudio.com/items?itemName=haskell.haskell) are only available in the default Dev Container. In order to use the Haskell extension, you must first configure the project for the tool used for building of your choice. See the documentation at [Contributing: Haskell Language Server](CONTRIBUTING.md#haskell-language-server) for cradles (`hie.yaml` files) that should suffice to configure the HLS explicitly for `./Setup.hs` and each of the buildable components in Stack's Cabal file. ### Haskell extension Choose `Manually via PATH` when asked the following question: Manage HLS ## Issues If there is a problem with a Dev Container, please [open an issue](https://github.com/benz0li/ghc-musl/issues/new) at its [parent images](#parent-images)' repository at [https://github.com/benz0li/ghc-musl](https://github.com/benz0li/ghc-musl). stack-3.7.1/doc/faq.md0000644000000000000000000006521014756610456012675 0ustar0000000000000000
# Frequently asked questions ## Stack and Cabal ??? question "What is the relationship between Stack and Cabal?" 'Cabal' can refer to Cabal (the library) or to Cabal (the tool). === "Cabal (the library)" Cabal (the library) is used by Stack to build your Haskell code. A Haskell package is described by a Cabal file, which file is part of the package. The file is named `.cabal`. Stack requires a project-level configuration file (`stack.yaml`, by default). For further information about the difference between a Cabal file and a project-level configuration file, see the [stack.yaml vs a Cabal file](topics/stack_yaml_vs_cabal_package_file.md) documentation. The [`stack init`](commands/init_command.md) command initializes a project-level configuration file from package description files. Stack uses Cabal (the library) via an executable. For `build-type: Simple` (the most common case), Stack builds that executable using the version of Cabal which came with GHC. Stack caches such executables, in the [Stack root](topics/stack_root.md) under directory `setup-exe-cache`. In rare or complex cases, a different version of Cabal to the one that came with GHC may be needed. `build-type: Custom` and a `setup-custom` stanza in the Cabal file, and a `Setup.hs` file in the package directory, can be specified. Stack's project-level configuration file can then specify the version of Cabal that Stack will use to build the executable (named `setup`) from `Setup.hs`. Stack will use Cabal via `setup`. === "Cabal (the tool)" Cabal (the tool) is a tool provided by the [`cabal-install`](https://hackage.haskell.org/package/cabal-install) Haskell package. It aims to simplify the process of managing Haskell software by automating the fetching, configuration, compilation and installation of Haskell libraries and programs. These are goals that Stack shares. Stack can be used independently of Cabal (the tool) but users can also use both, if they wish. ??? question "How do I use Stack with sandboxes?" A 'sandbox' is a development environment that is isolated from other parts of the system. The concept of sandboxing is built in to Stack. All builds are automatically isolated into separate package databases. ??? question "Can I run `cabal` commands inside `stack exec`?" Yes. Some `cabal` commands are inconsistent with the `GHC_PACKAGE_PATH` environment variable in the Stack environment. Command, for example: ~~~text stack exec --no-ghc-package-path -- cabal build ~~~ ## GHC or GHCi-related ??? question "Will Stack interfere with the GHC I already have installed?" No. ??? question "I already have GHC installed. Can I still use Stack?" Yes. In its default configuration, Stack will simply ignore any system GHC installation and use a sandboxed GHC that it has installed itself. You can find these sandboxed GHC installations in the `ghc-*` directories in the `stack path --programs` directory. If you would like Stack to use your system GHC installation, use the [`--system-ghc`](configure/yaml/non-project.md#system-ghc) flag or run `stack config set system-ghc --global true` to make Stack check your PATH for a suitable GHC by default. Stack can only use a system GHC installation if its version is compatible with the configuration of the current project, particularly the snapshot specified by the [`snapshot`](configure/yaml/project.md#snapshot) or [`resolver`](configure/yaml/project.md#resolver) key. GHC installation doesn't work for all operating systems, so in some cases you will need to use `system-ghc` and install GHC yourself. ??? question "When I command `stack ghci` what version of GHC is used?" The version of GHC is specified by the snapshot in the relevant Stack project-level configuration file. This may be the file in the `global-project` directory in the [Stack root](topics/stack_root.md). For further information, see the [configuration](configure/yaml/index.md) documentation. ??? question "How does Stack determine what GHC to use?" In its default configuration, Stack determines from the current project which GHC version, architecture etc it needs. It then looks in the `ghc-` subdirectory of the `stack path --programs` directory for a compatible GHC, requesting to install one via `stack setup` if none is found. If you are using the [`--system-ghc`](configure/yaml/non-project.md#system-ghc) flag or have configured `system-ghc: true` either in the project `stack.yaml` or the global `config.yaml`, Stack will use the first GHC that it finds on your PATH, falling back on its sandboxed installations only if the found GHC doesn't comply with the various requirements (version, architecture) that your project needs. See issue [#420](https://github.com/commercialhaskell/stack/issues/420) for a detailed discussion of Stack's behavior when `system-ghc` is enabled. ??? question "How can I test that different GHC versions can build my project?" You can create multiple project-level configuration files for your project, one for each build plan. For example, you might set up your project directory like so: ~~~text myproject/ stack-ghc-9.8.4.yaml stack-ghc-9.8.4.yaml stack.yaml --> symlink to stack-ghc-9.8.4.yaml myproject.cabal src/ ... ~~~ When you run `stack build`, you can set the `STACK_YAML` environment variable to indicate which build plan to use. Command: === "Unix-like" ~~~text STACK_YAML=stack-ghc-9.8.4.yaml stack build ~~~ === "Windows" ~~~text $Env:STACK_YAML='stack-ghc-9.8.4.yaml' stack build ~~~ === "Windows (Command Prompt)" ~~~text set STACK_YAML=stack-ghc-9.8.4.yaml stack build ~~~ ## Setup-related ??? question "Where is Stack installed?" Command: ~~~text stack uninstall ~~~ for information about where Stack is installed. ??? question "Can I change Stack's default temporary directory?" Stack downloads and extracts files to `$STACK_ROOT/programs` on most platforms, which defaults to `~/.stack/programs`. On Windows `$LOCALAPPDATA\Programs\stack` is used. If there is not enough free space in this directory, Stack may fail. For instance, `stack setup` with a GHC installation requires roughly 1GB free. If this is an issue, you can set `local-programs-path` in your `~/.stack/config.yaml` to a directory on a file system with more free space. If you use Stack with Nix integration, be aware that Nix uses a `TMPDIR` variable, and if it is not set Nix sets it to some subdirectory of `/run`, which on most Linuxes is a Ramdir. Nix will run the builds in `TMPDIR`, therefore if you don't have enough RAM you will get errors about disk space. If this happens to you, please _manually_ set `TMPDIR` before launching Stack to some directory on the disk. ??? question "On Windows, `stack setup` tells me to add certain paths to the PATH instead of doing it?" In PowerShell, it is easy to automate even that step. Command: ~~~text $Env:Path = ( stack setup | %{ $_ -replace '[^ ]+ ', ''} ), $Env:Path -join ";" ~~~ ??? question "Does Stack install the system/C libraries that some Cabal packages depend on?" No. This is currently out of the scope of Stack's target set of features. Instead of attempting to automate the installation of 3rd party dependencies, we have the following approaches for handling system dependencies: * Nix and docker help make your build and execution environment deterministic and predictable. This way, you can install system dependencies into a container, and share this container with all developers. * If you have installed some libraries into a non-standard location, use the [`extra-lib-dirs`](configure/yaml/non-project.md#extra-lib-dirs) option or the [`extra-include-dirs`](configure/yaml/non-project.md#extra-include-dirs) option to specify it. In the future, Stack might give operating system-specific suggestions for how to install system libraries. ??? question "How can I make Stack aware of my custom SSL certificates?" === "Linux" Use the `SYSTEM_CERTIFICATE_PATH` environment variable to point at the directory where you keep your SSL certificates. === "macOS" In principle, you can use the following command to add a certificate to your system certificate keychain: ~~~bash sudo security add-trusted-cert -d -r trustRoot -k /Library/Keychains/System.keychain ~~~ Some users have reported issues with this approach, see issue [#907](https://github.com/commercialhaskell/stack/issues/907) for more information. ## Package description format-related ??? question "How does Stack support the Hpack specification?" The [Hpack](https://github.com/sol/hpack) package description format is an alternative to that used in a Cabal file. If a package directory contains an package description file in the Hpack format (`package.yaml`), Stack will use that file to create the corresponding Cabal file. [`stack init`](commands/init_command.md) will use Hpack format package description files, if they are present. The [`with-hpack`](configure/yaml/non-project.md#with-hpack) non-project specific configuration option or the [`--with-hpack`](configure/global_flags.md#-with-hpack-option) global flag can be used to specify an Hpack executable to use instead of Stack's built-in Hpack functionality. ## Package index-related ??? question "How do I update my package index?" Command: ~~~text stack update ~~~ However, generally, it's not necessary with Stack: if the package index is missing, or if a snapshot refers to package version that isn't available, Stack will automatically update the package index and then try again. If you run into a situation where Stack doesn't automatically update the package index, please report it as a bug. ??? question "Is it dangerous to update the package index automatically? Can that corrupt build plans?" No. Stack is explicit about which packages it's going to build. There are three sources of information to tell Stack which packages to install: the selected snapshot, the `extra-deps` configuration value, and your project packages. The only way to get Stack to change its build plan is to modify one of those three. Updating the index will have no effect on Stack's behavior. ??? question "How do I use a custom package index?" See the [`package-index`](configure/yaml/non-project.md#package-index) non-project specific configuration option documentation. ## Package-related ??? question "How do I use a package version on Hackage not in a snapshot?" Add the package version to the [`extra-deps`](configure/yaml/project.md) project-specific configuration option in the [project-level configuration file](configure/yaml/index.md). ??? question "How do I use a package version not on Hackage?" Add the location of the package version to the [`extra-deps`](configure/yaml/project.md) project-specific configuration option in the [project-level configuration file](configure/yaml/index.md). For further information, see the [package location](topics/package_location.md) documentation. ??? question "How do I use a modified version of a package?" Typically, a modified version of a package is used as a project package. Add the location of the package to the [`packages`](configure/yaml/project.md#packages) project-specific configuration option in the [project-level configuration file](configure/yaml/index.md). One way to get the source code for the unmodified package version is to use the [`stack unpack`](commands/unpack_command.md). ??? question "I'd like to use my installed packages in a different directory. How do I tell Stack where to find my packages?" Set the `STACK_YAML` environment variable to point to the `stack.yaml` configuration file for your project. Then you can run `stack exec`, `stack ghc`, etc., from any directory and still use your packages. ## `stack build`-related ??? question "Why does `stack build` fail with GHC 9.8.1 and 9.8.2 only?" If the Cabal file of the relevant package makes use of a `c-sources` field, the failure may be due to `Cabal-3.10.2.0` enforcing that the field can specify only `*.c` files. Earlier and later versions of Cabal (the library) tolerate other files. When the Cabal build type is not `Custom`, Stack builds with the `Cabal` boot package of the specified version of GHC. The boot package of GHC 9.8.1 and 9.8.2 is `Cabal-3.10.2.0`. ??? question "What causes dependency on multiple versions of the same package?" When building a package, during its configuration, Stack may warn: ~~~text This package indirectly depends on multiple versions of the same package. This is very likely to cause a compile failure. ~~~ and the build subsequently fails. Often the cause is that: (1) the package depends, directly or indirectly, on a GHC wired-in package (for example, the `ghc` package); and (2) a direct or indirect dependency of that wired-in package is also specified as an extra-dep but the versions differ. ??? question "Why does `stack test` trigger a rebuild of other components?" If the set of dependencies of a project package to be built are not a subset of the set of dependencies when it was last built, then that will trigger a rebuild of components that were previously built. The command: ~~~text stack build ~~~ will build the library and executable components of project packages and the build will take into account the dependencies of those components. If you then command: ~~~text stack test ~~~ or, equivalently: ~~~text stack build --test ~~~ the test suite components of project packages are added to the build targets. That can add dependencies to a project package, if its test suite components have dependencies that are not dependencies of its library and executable components. What is true of test suite components applies equally to benchmark components. If that behaviour is undesirable, a way to avoid it is to change the description of each project package so that adding its test suite (or benchmark) components does not add dependencies to the package. That is, to specify, in the package description, the dependencies as common to all the components that you are switching between from one build to another. For example, if you are using `package.yaml`, add the dependencies to its top-level `dependencies` key. Alternatively, build all components of project packages without running tests or benchmarks once built. Add the following to a configuration file: ~~~yaml build: test: true test-arguments: no-run-tests: true bench: true benchmark-opts: no-run-benchmarks: true ~~~ or command: ~~~text stack build --test --no-run-tests --bench --no-run-benchmarks ~~~ ??? question "How do I use a custom preprocessor?" See the [`customer-prepocessor-extensions`](configure/yaml/project.md#custom-preprocessor-extensions) project-specific configuration option documentation. ??? question "How do I get extra tools used during building?" Stack will automatically install tools used during building required by your packages or their dependencies, in particular [Alex](https://hackage.haskell.org/package/alex) and [Happy](https://hackage.haskell.org/package/happy). !!! note This works when using LTS or nightly snapshots, not with GHC or custom snapshots. You can manually install tools used during building by running, e.g., `stack build alex happy`. ??? question "My tests are failing. What should I do?" Like all other targets, `stack test` runs test suites in parallel by default. This can cause problems with test suites that depend on global resources such as a database or binding to a fixed port number. A quick hack is to force stack to run all test suites in sequence, using `stack test --jobs=1`. For test suites to run in parallel developers should ensure that their test suites do not depend on global resources (e.g. by asking the operating system for a random port to bind to) and where unavoidable, add a lock in order to serialize access to shared resources. ??? question "How do I use Stack with Docker?" See the [Docker integration](topics/docker_integration.md) documentation. ??? question "How do I build a statically-linked executable on Linux?" The way that Stack itself builds statically-linked Stack executables for Linux is as follows: * In the Cabal file, the following [`ld-options`](https://cabal.readthedocs.io/en/stable/cabal-package-description-file.html#pkg-field-ld-options) are set: `-static` and `-pthread`. * The Stack command is run in a Docker container based on Alpine Linux. The relevant Docker image repository is set out in Stack's `stack.yaml` file. See also Olivier Benz's [GHC musl project](https://gitlab.com/benz0li/ghc-musl). * Stack's configuration includes: ~~~yaml extra-include-dirs: - /usr/include extra-lib-dirs: - /lib - /usr/lib ~~~ * The build command is `stack build --docker --system-ghc --no-install-ghc` (on x86_64) or `stack build --docker --docker-stack-exe=image --system-ghc --no-install-ghc` (on AArch64; the host Stack and the image Stack must have the same version number). ??? question "Why doesn't Stack rebuild my project when I specify `--ghc-options` on the command line?" Because GHC options often only affect optimization levels and warning behavior, Stack doesn't recompile when it detects an option change by default. This behavior can be changed though by setting the [`rebuild-ghc-options` option](configure/yaml/non-project.md#rebuild-ghc-options) to `true`. To force recompilation manually, use the `--force-dirty` flag. If this still doesn't lead to a rebuild, add the `-fforce-recomp` flag to your `--ghc-options`. ??? question "Why doesn't Stack apply my `--ghc-options` to my dependencies?" By default, Stack applies command line GHC options only to [project packages](configure/yaml/project.md#packages). For an explanation of this choice see this discussion on issue [#827](https://github.com/commercialhaskell/stack/issues/827#issuecomment-133263678). If you still want to set specific GHC options for a dependency, use the [`ghc-options`](configure/yaml/non-project.md#ghc-options) option in your YAML configuration file. To change the set of packages that command line GHC options apply to, use the [`apply-ghc-options`](configure/yaml/non-project.md#apply-ghc-options) option. ??? question "How does Stack handle parallel builds?" See issue [#644](https://github.com/commercialhaskell/stack/issues/644) for more details. ??? question "Where does the output from `--ghc-options=-ddump-splices` (and other `-ddump*` options) go?" These are written to `*.dump-*` files inside the package's `.stack-work` directory. Specifically, they will be available at `PKG-DIR/$(stack path --dist-dir)/build/SOURCE-PATH`, where `SOURCE-PATH` is the path to the source file, relative to the location of the Cabal file. When building named components such as test-suites, `SOURCE-PATH` will also include `COMPONENT/COMPONENT-tmp`, where `COMPONENT` is the name of the component. ??? question "Why is DYLD_LIBRARY_PATH ignored?" If you are on Mac OS X 10.11 ("El Capitan") or later, there is a GHC issue [#11617](https://ghc.haskell.org/trac/ghc/ticket/11617) which prevents the `DYLD_LIBRARY_PATH` environment variable from being passed to GHC (see issue [#1161](https://github.com/commercialhaskell/stack/issues/1161)) when System Integrity Protection (a.k.a. "rootless") is enabled. There are two known workarounds: 1. Known to work in all cases: [disable System Integrity Protection](http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x/). **WARNING: Disabling SIP will severely reduce the security of your system, so only do this if absolutely necessary!** 2. Experimental: modify GHC's shell script wrappers to use a shell outside the protected directories (see issue [#1161](https://github.com/commercialhaskell/stack/issues/1161#issuecomment-186690904)). ??? question "How do I get `verbose` output from GHC when I build?" Set the [`--ghc-options`](commands/build_command.md#-ghc-options-option) option of `stack build` to `-v`. ## Snapshot-related ??? question "How does Stack choose which snapshot to use when creating a project-level configuration file?" See the [`stack init`](commands/init_command.md) command documentation. ## CI-related ??? question "How do I use Stack with Travis CI?" See the [Travis CI](topics/travis_ci.md) documentation. ??? question "How do I use Stack with Azure CI?" See the [Azure CI](topics/azure_ci.md) documentation. ## Linux-related ??? question "How do fix error [S-9443] for 'linux64-ncurses6'?" Most Linux distributions have standardized on providing `libtinfo.so.6`, either directly or as a symbolic link to `libncursesw.so.6`. As such, there are no GHC binary distributions that link to `libncursesw.so.6` after GHC 8.2.2. This error can be prevented by creating a symbolic link to `libncursesw.so.6` using name `libtinfo.so.6`. Command: ~~~bash ln -s /usr/lib/libncursesw.so.6 /usr/lib/libtinfo.so.6 ~~~ Root privileges may be required. ## macOS-related ??? question "On macOS, how do I resolve linker errors when running `stack setup` or `stack build`?" This is likely to be caused by having both a LLVM installation and default Apple Clang compiler on the PATH. The symptom of this issue is a linker error "bad relocation (Invalid pointer diff)". The compiler picks up inconsistent versions of binaries and the mysterious error occurs. The workaround is to remove LLVM binaries from the PATH. ??? question "On macOS, how do I suppress `'-nopie'` warnings with `stack build`?" ~~~bash clang: warning: argument unused during compilation: '-nopie' [-Wunused-command-line-argument] ~~~ This warning is shown when compiler support of `-no-pie` is expected but unavailable. It's possible to bypass the warning for a specific version of GHC by modifying a global setting: ~~~bash # ~/.stack/programs/x86_64-osx/ghc-8.2.2/lib/ghc-8.2.2/settings -- ("C compiler supports -no-pie", "YES"), ++ ("C compiler supports -no-pie", "NO"), ~~~ **Note that we're fixing `ghc-8.2.2` in this case; repeat for other versions as necessary.** You should apply this fix for the version of GHC that matches your snapshot. Issue [#4009](https://github.com/commercialhaskell/stack/issues/4009) goes into further detail. ## Windows-related ??? question "What is licensing restrictions on Windows?" Currently, on Windows, GHC produces binaries linked statically with [GNU Multiple Precision Arithmetic Library](https://gmplib.org/) (GMP), which is used by [integer-gmp](https://hackage.haskell.org/package/integer-gmp) library to provide big integer implementation for Haskell. Contrary to the majority of Haskell code licensed under permissive BSD3 license, GMP library is licensed under LGPL, which means resulting binaries [have to be provided with source code or object files](http://www.gnu.org/licenses/gpl-faq.html#LGPLStaticVsDynamic). That may or may not be acceptable for your situation. Current workaround is to use GHC built with alternative big integer implementation called `integer-simple`, which is free from LGPL limitations as it's pure Haskell and does not use GMP. Unfortunately it has yet to be available out of the box with Stack. See issue [#399](https://github.com/commercialhaskell/stack/issues/399) for the ongoing effort and information on workarounds. ??? question "I have a Windows username with a space in it and problems building" See the [`local-programs-path`](configure/yaml/non-project.md#local-programs-path) non-project specific configuration option documentation for advice. ??? question "How to get a working executable on Windows?" When executing a binary after building with `stack build` (e.g. for target "foo"), the command `foo.exe` might complain about missing runtime libraries (whereas `stack exec foo` works). Windows is not able to find the necessary C++ libraries from the standard prompt because they're not in the PATH environment variable. `stack exec` works because it's modifying PATH to include extra things. Those libraries are shipped with GHC (and, theoretically in some cases, MSYS2). The easiest way to find them is `stack exec which`. For example, command: ~~~text stack exec -- which libstdc++-6.dll /c/Users/Michael/AppData/Local/Programs/stack/i386-windows/ghc-7.8.4/mingw/bin/libstdc++-6.dll ~~~ A quick workaround is adding this path to the PATH environment variable or copying the files somewhere Windows finds them (see https://msdn.microsoft.com/de-de/library/7d83bc18.aspx).

# Setting up The goal of setting up is a `stack` executable file on the PATH. When Stack is used, it sets other things up as needed. *[PATH]: An environment variable that specifies a list of directories searched for executable files. ??? question "How do I know if Stack is on the PATH?" Command `stack`. If Stack is available, that should output information about how to use it. ??? question "How do I find where Stack is located?" === "Unix-like" Command `which -a stack`. === "Windows" Command `where.exe stack`. ??? question "How do I find what version of Stack is available?" Command `stack --version` or `stack --numeric-version`. ??? question "If I don't use GHCup, is there a preferred location for Stack?" You can put the `stack` executable file anywhere on your PATH. However, a good location is the directory where Stack itself will install executables. That location depends on the operating system: === "Unix-like" Stack installs executables to: ~~~text $HOME/.local/bin ~~~ If you don't have that directory in your PATH, you may need to update your PATH. That can be done by editing the `~/.bashrc` file. === "Windows" Stack installs executables to: ~~~text $Env:APPDATA\local\bin ~~~ For example: `C:\Users\\AppData\Roaming\local\bin`. If you don't have that directory in your PATH, you may need to update your PATH. That can be done by searching for 'Edit Environment variables for your account' under Start. === "Windows (Command Prompt)" Stack installs executables to: ~~~text %APPDATA%\local\bin ~~~ For example: `C:\Users\\AppData\Roaming\local\bin`. If you don't have that directory in your PATH, you may need to update your PATH. That can be done by searching for 'Edit Environment variables for your account' under Start. !!! note If you used GHCup to install Stack, GHCup puts executable files in the `bin` directory in the GHCup root directory. To get and use Stack, some other things need to be in place first:
- :material-laptop:{ .lg .middle } __A computer__ --- Stack will need at least about 5 GB of disk space[^1]. It will help to know what platform your computer provides. [^1]: About 3 GB for a single version of GHC and about 2 GB for a local copy of the Hackage package index. *[platform]: Machine architecture (eg x86_64, AArch64) and operating system (eg Linux distribution, macOS, Windows). - :material-wifi:{ .lg .middle } __Access to the Internet__ --- Stack will need to fetch files from remote locations. - :octicons-terminal-24:{ .lg .middle } __Terminal software__ --- Stack is used at the command line. Your operating system likely provides terminal software and alternatives may be available. - :material-text-box-edit-outline:{ .lg .middle } __A code editor__ --- You can use any editor program that can edit text files but code editors with extensions for Haskell code files are recommended.
## Install Stack Stack can be installed on most Linux distributions, macOS and Windows. ??? question "What about other operating systems?" Stack is open to supporting more operating systems. To request support for an operating system, please submit an [issue](https://github.com/commercialhaskell/stack/issues/new) at Stack's GitHub repository. Stack can be installed directly or by using the GHCup tool. === "Directly" Stack can be installed on various operating systems. ??? question "Where can binary distributions for Stack be found?" Stack executables are available on the [releases](https://github.com/commercialhaskell/stack/releases) page of Stack's GitHub repository. URLs with the format `https://get.haskellstack.org/stable/.` point to the latest stable release. The manual download links use those URLs. ??? question "Does the `sh` installation script have flags and options?" The `sh` installation script recognises the following optional flags and options: `-q` suppresses output and specifies non-intervention (likely a prerequisite for the use of the script in CI environments); `-f` forces installation, even if an existing Stack executable is detected; and `-d ` specifies a destination directory for the Stack executable. === "Linux" For most Linux distributions, on x86_64 or AArch64 machine architectures, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions for your platform below. ??? question "Can I download Stack manually?" Yes. Manual download for Linux distributions depends on your machine architecture, x86_64 or AArch64/ARM64. === "x86_64" * Click [:material-cloud-download-outline:](https://get.haskellstack.org/stable/linux-x86_64.tar.gz) to download an archive file with the latest release. * Extract the archive and place the `stack` executable file somewhere on your PATH. * Ensure you have the required system dependencies installed. These include GCC, GNU Make, xz, perl, libgmp, libffi, and zlib. We also recommend Git and GPG. The installation of system dependencies will depend on the package manager for your Linux distribution. Notes are provided for Arch Linux, CentOS, Debian, Fedora, Gentoo and Ubuntu. === "Arch Linux" ~~~text sudo pacman -S make gcc ncurses git gnupg xz zlib gmp libffi zlib ~~~ === "CentOS" ~~~text sudo yum install perl make automake gcc gmp-devel libffi zlib zlib-devel xz tar git gnupg ~~~ === "Debian" ~~~text sudo apt-get install g++ gcc libc6-dev libffi-dev libgmp-dev make xz-utils zlib1g-dev git gnupg netbase ~~~ === "Fedora" ~~~text sudo dnf install perl make automake gcc gmp-devel libffi zlib zlib-devel xz tar git gnupg ~~~ === "Gentoo" Ensure you have the `ncurses` package with `USE=tinfo`. Without it, Stack will not be able to install GHC. === "Ubuntu" ~~~text sudo apt-get install g++ gcc libc6-dev libffi-dev libgmp-dev make xz-utils zlib1g-dev git gnupg netbase ~~~ === "AArch64" * Click [:material-cloud-download-outline:](https://get.haskellstack.org/stable/linux-aarch64.tar.gz) to download an archive file with the latest release. * Extract the archive and place the `stack` executable file somewhere on your PATH. * Ensure you have the required system dependencies installed. These include GCC, GNU Make, xz, perl, libgmp, libffi, and zlib. We also recommend Git and GPG. The installation of system dependencies will depend on the package manager for your Linux distribution. Notes are provided for Arch Linux, CentOS, Debian, Fedora, Gentoo and Ubuntu. === "Arch Linux" ~~~text sudo pacman -S make gcc ncurses git gnupg xz zlib gmp libffi zlib ~~~ === "CentOS" ~~~text sudo yum install perl make automake gcc gmp-devel libffi zlib zlib-devel xz tar git gnupg ~~~ === "Debian" ~~~text sudo apt-get install g++ gcc libc6-dev libffi-dev libgmp-dev make xz-utils zlib1g-dev git gnupg netbase ~~~ === "Fedora" ~~~text sudo dnf install perl make automake gcc gmp-devel libffi zlib zlib-devel xz tar git gnupg ~~~ === "Gentoo" Ensure you have the `ncurses` package with `USE=tinfo`. Without it, Stack will not be able to install GHC. === "Ubuntu" ~~~text sudo apt-get install g++ gcc libc6-dev libffi-dev libgmp-dev make xz-utils zlib1g-dev git gnupg netbase ~~~ ??? question "Can I use a Linux package to get Stack?" Some Linux distributions have official or unofficial packages for Stack, including Arch Linux, Debian, Fedora, NixOS, openSUSE/SUSE Linux Enterprise, and Ubuntu. However, the Stack version available as a Linux package may lag behind Stack's current version and, in some cases, the lag may be significant. !!! info "Linux packages that lag behind Stack's current version" If Stack version available as a Linux package lags behind Stack's current version, using `stack upgrade --binary-only` is recommended after installing it. === "Arch Linux" The Arch extra package repository provides an official x86_64 [package](https://www.archlinux.org/packages/extra/x86_64/stack/). You can install it with the command: ~~~text sudo pacman -S stack ~~~ The Arch User Repository (AUR) also provides: * a [`stack-bin` package](https://aur.archlinux.org/packages/stack-bin); and * a [`stack-static` package](https://aur.archlinux.org/packages/stack-static) === "Debian" There are Debian [packages](https://packages.debian.org/search?keywords=haskell-stack&searchon=names&suite=all§ion=all) for Buster and up. However, the distribution's Stack version lags behind. === "Fedora" Fedora includes Stack, but its Stack version may lag behind. === "NixOS" Users who follow the `nixos-unstable` channel or the Nixpkgs `master` branch can install the latest Stack release into their profile with the command: ~~~text nix-env -f "" -iA stack ~~~ Alternatively, the package can be built from source as follows. 1. Clone the git repo, with the command: ~~~text git clone https://github.com/commercialhaskell/stack.git ~~~ 2. Create a `shell.nix` file with the command: ~~~text cabal2nix --shell ./. --no-check --no-haddock > shell.nix ~~~ Note that the tests fail on NixOS, so disable them with `--no-check`. Also, Haddock currently doesn't work for Stack, so `--no-haddock` disables it. 3. Install Stack to your user profile with the command: ~~~text nix-env -i -f shell.nix ~~~ For more information on using Stack together with Nix, please see the [NixOS manual section on Stack](http://nixos.org/nixpkgs/manual/#how-to-build-a-haskell-project-using-stack). === "SUSE" There is also an unofficial package for openSUSE or SUSE Linux Enterprise. Its Stack version may lag behind. To install it: === "openSUSE Tumbleweed" ~~~text sudo zypper in stack ~~~ === "openSUSE Leap" ~~~text sudo zypper ar http://download.opensuse.org/repositories/devel:/languages:/haskell/openSUSE_Leap_42.1/devel:languages:haskell.repo sudo zypper in stack ~~~ === "SUSE Linux Enterprise 12" ~~~text sudo zypper ar http://download.opensuse.org/repositories/devel:/languages:/haskell/SLE_12/devel:languages:haskell.repo sudo zypper in stack ~~~ === "Ubuntu" There are Ubuntu [packages](http://packages.ubuntu.com/search?keywords=haskell-stack&searchon=names&suite=all§ion=all) for Ubuntu 20.04 and up. ??? question "Can I set up auto-completion of Stack commands?" Yes. For further information, see the [shell auto-completion](topics/shell_autocompletion.md) documentation. === "macOS" Most users of Stack on macOS will also have up to date tools for software development. ??? question "What if I am not sure that I have those tools?" macOS does not come with all the tools required for software development but a collection of useful tools, known as the Xcode Command Line Tools, is readily available. A version of that collection is provided with each version of Xcode (Apple’s integrated development environment) and can also be obtained from Apple separately from Xcode. The collection also includes the macOS SDK (software development kit). The macOS SDK provides header files for macOS APIs. If you use a command that refers to a common Xcode Command Line Tool and the Xcode Command Line Tools are not installed, macOS may prompt you to install the tools. macOS also comes with a command line tool, `xcode-select`, that can be used to obtain the Xcode Command Line Tools. Command `xcode-select --print-path` to print the path to the currently selected (active) developer directory. If the directory does not exist, or is empty, then the Xcode Command Line Tools are not installed. If the Xcode Command Line Tools are not installed, command `xcode-select --install` to open a user interface dialog to request automatic installation of the tools. An upgrade of macOS may sometimes require the existing Xcode Command Line Tools to be uninstalled and an updated version of the tools to be installed. The existing tools can be uninstalled by deleting the directory reported by `xcode-select --print-path`. If, after the installation of Stack, running `stack setup` fails with: ~~~text configure: error: cannot run C compiled programs. ~~~ that indicates that the Xcode Command Line Tools are not installed. If building fails with messages that `*.h` files are not found, that may also indicate that Xcode Command Line Tools are not up to date. Xcode 10 provided an SDK for macOS 10.14 (Mojave) and [changed the location](https://developer.apple.com/documentation/xcode-release-notes/xcode-10-release-notes#Command-Line-Tools) of the macOS system headers. As a workaround, an extra package was provided by Apple which installed the headers to the base system under `/usr/include`. ??? question "What versions of the LLVM compiler and toolchain are supported?" The documentation for each version of GHC identifies the versions of LLVM that are supported. That is summarised in the table below for recent versions of GHC: |GHC version|LLVM versions| |-----------|-------------| |9.12.2 |11 to 15 | |9.10.1 |11 to 15 | |9.8.4 |11 to 15 | |9.6.7 |11 to 15 | |9.4.8 |10 to 14 | |9.2.8 |9 to 12 | |9.0.2 |9, 10 or 12 | |8.10.7 |9 to 12 | |8.8.4 |7 | |8.6.5 |6 | |8.4.4 |5 | From late 2020, Apple began a transition from Mac computers with Intel processors (Intel-based Mac) to [Mac computers with Apple silicon](https://support.apple.com/en-gb/HT211814). === "Intel-based" Intel-based Mac computers have processors with x86_64 architectures. For most Intel-based Mac computers, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions below. ??? question "Can I download Stack manually?" Yes: * Click [:material-cloud-download-outline:](https://get.haskellstack.org/stable/osx-x86_64.tar.gz) to download an archive file with the latest release for x86_64 architectures. * Extract the archive and place `stack` somewhere on your PATH. Now you can run Stack from the command line in a terminal. === "Apple silicon" Mac computers with Apple silicon have an M series chip. These chips use an architecture known as ARM64 or AArch64. For Mac computers with Apple silicon, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions below. ??? question "What if I get error `C compiler cannot build executables`?" The installation of Stack or some packages (e.g. `network`) requiring C source compilation might fail with: ~~~text configure: error: C compiler cannot build executables ~~~ In that case you should pass `-arch arm64` as part of the `CFLAGS` environment variable. This setting will be picked up by the C compiler of your choice. ~~~bash # Assuming BASH below # passing CFLAGS in-line with the command giving rise to the error CFLAGS="-arch arm64 ${CFLAGS:-}" some_command_to_install_stack CFLAGS="-arch arm64 ${CFLAGS:-}" stack [build|install] # -- OR -- # ~/.bash_profile # NOTE: only do this if you do not have to cross-compile, or remember to unset # CFLAGS when needed export CFLAGS="-arch arm64 ${CFLAGS:-}" ~~~ The setting instructs the C compiler to compile objects for ARM64. These can then be linked with libraries built for ARM64. Without the instruction, the C compiler, invoked by Cabal running in x86-64, would compile x86-64 objects and attempt to link them with existing ARM64 libraries, resulting in the error above. ??? question "Can I download Stack manually?" Yes: * Click [:material-cloud-download-outline:](https://get.haskellstack.org/stable/osx-aarch64.tar.gz) to download an archive file with the latest release for AArch64 architectures. * Extract the archive and place `stack` somewhere on your PATH. Now you can run Stack from the command line in a terminal. ??? question "Can I use the Homebrew package manager to get Stack?" [Homebrew](https://brew.sh/) is a popular package manager for macOS. If you have its `brew` tool installed, you can just command: ~~~text brew install haskell-stack ~~~ * The Homebrew formula and bottles are **unofficial** and lag slightly behind new Stack releases, but tend to be updated within a day or two. * Normally, Homebrew will install from a pre-built binary (aka "pour from a bottle"), but if it starts trying to build everything from source (which will take hours), see [their FAQ on the topic](https://github.com/Homebrew/brew/blob/master/docs/FAQ.md#why-do-you-compile-everything). ??? question "Can I set up auto-completion of Stack commands?" Yes. For further information, see the [shell auto-completion](topics/shell_autocompletion.md) documentation. === "Windows" Most computers using Windows have a x86_64 machine architecture. More recently, Microsoft has provided Windows on Arm that runs on other processors. === "x86_64" On 64-bit Windows, the easiest way to install Stack is to download and use the [Windows installer](https://get.haskellstack.org/stable/windows-x86_64-installer.exe). !!! info "Stack root" By default, the Windows installer will set the [Stack root](topics/stack_root.md) by setting the `STACK_ROOT` environment variable to `C:\sr`. !!! note "Anti-virus software" Systems with antivirus software may need to add Stack to the list of 'trusted' applications. You may see a "Windows Defender SmartScreen prevented an unrecognized app from starting" warning when you try to run the installer. If so, click on **More info**, and then click on the **Run anyway** button that appears. ??? warning "I have a Windows username with a space in it" GHC 9.4.1 and later have a bug which means they do not work if the path to the `ghc` executable has a space character in it. The default location for Stack's 'programs' directory will have a space in the path if the value of the `USERNAME` environment variable includes a space. A solution is to configure Stack to use a different location for its 'programs' directory. For further information, see the [`local-programs-path`](configure/yaml/non-project.md#local-programs-path) non-project specific configuration option documentation. ??? warning "Stack 2.9.1, 2.9.3 and 2.11.1: Long user PATH environment variable" The Windows installer for Stack 2.9.1, 2.9.3 and 2.11.1 (only) will replace the user `PATH` environment variable (rather than append to it) if a 1024 character limit is exceeded. If the content of your existing user `PATH` is long, preserve it before running the installer. We recommend installing to the default location with the installer, as that will make `stack install` and `stack upgrade` work correctly out of the box. ??? question "Can I download Stack manually?" Yes: * Click [:material-cloud-download-outline:](https://get.haskellstack.org/stable/windows-x86_64.zip) to download an archive file with the latest release. * Unpack the archive and place `stack.exe` somewhere on your PATH. Now you can run Stack from the command line in a terminal. === "Windows on Arm" The GHC project does not yet provide a version of GHC that runs on Windows on Arm. ??? note "China-based users: download" As of 24 February 2020, the download link has limited connectivity from within mainland China. If you experience this, please proceed by manually downloading (ideally via a VPN) and installing Stack following the instructions on this page that apply to your operating system. === "GHCup" The separate [GHCup](https://www.haskell.org/ghcup/) project provides a tool that can be used to install Stack and other Haskell-related tools, including GHC and [Haskell Language Server](https://github.com/haskell/haskell-language-server) (HLS). HLS is a program that is used by Haskell extensions for popular code editors. GHCup provides Stack for some combinations of machine architecture and operating system not provided elsewhere. By default, the script to install GHCup (which can be run more than once) also configures Stack so that if Stack needs a version of GHC, GHCup takes over obtaining and installing that version. ??? note "China-based users: configuration" After installation, Stack will need to be configured before it can download large files consistently from within China (without reliance on a VPN). Please add the following to the bottom of the [global configuration file](configure/yaml/index.md) (`config.yaml`): ~~~yaml ###ADD THIS IF YOU LIVE IN CHINA setup-info-locations: - "http://mirrors.tuna.tsinghua.edu.cn/stackage/stack-setup.yaml" urls: latest-snapshot: http://mirrors.tuna.tsinghua.edu.cn/stackage/snapshots.json package-index: - download-prefix: http://mirrors.tuna.tsinghua.edu.cn/hackage/ ~~~ ??? question "What if I am using an HTTP proxy?" To use Stack behind a HTTP proxy with IP address *IP* and port *PORT*, first set up an environment variable `http_proxy` and then run the Stack command. For example: === "Unix-like" ~~~text export http_proxy=IP:PORT stack install ~~~ On most operating systems, it is not mandatory for programs to follow the 'system-wide' HTTP proxy. Some programs, such as browsers, do honor this 'system-wide' HTTP proxy setting, while other programs, including Bash, do not. That means configuring 'http proxy setting' in your System Preferences (macOS) would not result in Stack traffic going through the proxy. === "Windows" ~~~text $Env:http_proxy=IP:PORT stack install ~~~ It is not mandatory for programs to follow the 'system-wide' HTTP proxy. Some programs, such as browsers, do honor this 'system-wide' HTTP proxy setting, while other programs do not. That means configuring 'http proxy setting' in your Control Panel would not result in Stack traffic going through the proxy. === "Windows (Command Prompt)" ~~~text set http_proxy=IP:PORT stack install ~~~ It is not mandatory for programs to follow the 'system-wide' HTTP proxy. Some programs, such as browsers, do honor this 'system-wide' HTTP proxy setting, while other programs do not. That means configuring 'http proxy setting' in your Control Panel would not result in Stack traffic going through the proxy. ## Upgrade Stack The Stack project recommends the use of the latest released version of Stack. If Stack is already installed, upgrading it depends on whether you are using Stack or GHCup to manage versions of Stack. === "Stack" ??? warning "If you use GHCup to manage versions of Stack, use it consistently" If you used GHCup to install Stack, you should also use GHCup to upgrade Stack. GHCup uses an executable named `stack` to manage versions of Stack, through a file `stack.shim`. Stack will likely overwrite the executable on upgrade. There are different approaches to upgrading Stack, which vary as between Unix-like operating systems (including macOS) and Windows. === "Unix-like" There are essentially four different approaches:
- __Use the `stack upgrade` command__ --- For further information, see the [`stack upgrade`](commands/upgrade_command.md) documentation. - __Manual download__ --- Follow the steps above to download manually the newest executable and replace the old executable. - __Use the `sh` installation script__ --- Use the `get.haskellstack.org` script with its `-f` flag to overwrite the current Stack executable. For example, command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh -s - -f ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh -s - -f ~~~ - __Use a package manager__ --- Follow your normal package manager approach to upgrading. For example: ~~~text apt-get update apt-get upgrade ~~~ Be aware that officially released binaries from the distribution may lag behind the latest version of Stack significantly.
=== "Windows" There are essentially two different approaches:
- __Use the `stack upgrade` command__ --- For further information, see the [`stack upgrade`](commands/upgrade_command.md) documentation. - __Manual download__ --- Follow the steps above to download manually the newest executable and replace the old executable.
=== "GHCup" The separate [GHCup](https://www.haskell.org/ghcup/) project provides guidance about how to use GHCup to manage versions of tools such as Stack. stack-3.7.1/doc/maintainers/7zip.md0000644000000000000000000000731314646722726015333 0ustar0000000000000000
# Upgrading 7-Zip When installing GHC or MSYS2 on Windows, Stack will also install [7-Zip](https://www.7-zip.org/). 7-Zip is a file archiver and is used by Stack to extract files from archives. This section explains the steps required to upgrade the 7-Zip version used by Stack. The 7-Zip functionality used by Stack is mature and stable. It is anticipated that the Stack-supplied 7-Zip will not need to be updated frequently. On 10 September 2022, it was updated from 7-Zip 9.20 (released on 18 November 2010) to 7-Zip 22.01 (released on 15 July 2022). 1. Download the latest installer for 64-bit x64 Windows from 7-Zip's website. 2. Run the installer and install to the default location (`C:\C:\Program Files\7-Zip`). The four relevant files from those installed will be: ~~~text 7z.exe # 7-Zip Console 7z.dll # 7-Zip Engine license.txt # 7-Zip License readme.txt # 7-Zip Overview ~~~ 3. In the [commercialhaskell/stackage-content](https://github.com/commercialhaskell/stackage-content) GitHub repository, create a new draft release tagged and named `7z-XX.YY`, where `XX.YY` is the 7-Zip version number. 4. Upload the four relevant files in step 2 above into the draft release. 5. Provide a description for the release. For example: ~~~text 7-Zip 22.01 (2022-07-15) for Windows 64-bit x64. ~~~ 6. Publish the release. 7. Changes need to be made to the [stackage-content/stack/stack-setup-2.yaml](https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml) file, to switch over to using the newly uploaded files. For example (extract): ~~~yaml sevenzexe-info: url: "https://github.com/commercialhaskell/stackage-content/releases/download/7z-22.01/7z.exe" content-length: 545280 sha256: 254cf6411d38903b2440819f7e0a847f0cfee7f8096cfad9e90fea62f42b0c23 sevenzdll-info: url: "https://github.com/commercialhaskell/stackage-content/releases/download/7z-22.01/7z.dll" content-length: 1814016 sha256: 73578f14d50f747efa82527a503f1ad542f9db170e2901eddb54d6bce93fc00e ~~~ The `content-length:` key's value is the size of the file in bytes. It can be obtained from the `Length` field of the `dir` command. The `sha256:` key's value can be obtained from the commands (in PowerShell): ~~~text (Get-FileHash 7z.exe -Algorithm SHA256).Hash.ToLower() (Get-FileHash 7z.dll -Algorithm SHA256).Hash.ToLower() ~~~ The `sha256:` key only accepts lowercase hash results as values. 8. The changed `stack-setup-2.yaml` file should be tested locally. This can be done by: * temporarily disabling the existing local copy of 7-Zip by changing the name of the `7z.exe` and `7z.dll` files in the `stack path --programs` directory; * identifying a version of GHC not already installed in the `stack path --programs` directory; and * executing the command: ~~~text stack --snapshot setup --setup-info-yaml ~~~ where `` requires the missing version of GHC. If all is well, the command should proceed to download the missing version of GHC, download the `7z.exe` and `7z.dll` files, and use the 7-Zip version to extract files from the GHC archive. 9. Raise a pull request on `commercialhaskell/stackage-contents` for the changes to the locally-tested `stack-setup-2.yaml` file. stack-3.7.1/doc/maintainers/archive/docker.md0000644000000000000000000001524115023557525017322 0ustar0000000000000000
# Docker images Each Stackage LTS release has two corresponding docker images in the [fpco/stack-build](https://hub.docker.com/r/fpco/stack-build/) and [fpco/stack-build-small](https://hub.docker.com/r/fpco/stack-build-small/) repositories. The former contains every system library needed to build any package in the snapshot, while the latter only contains a minimal set of system libraries for basic programs. The Dockerfiles for building these images are in [stackage/automated/dockerfiles](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/). There is also a [build.sh](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/build.sh) script to help with building and pushing the images (see the [README](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/README.md) for usage instructions). ## Build images for new minor LTS snapshot In most cases, a new minor LTS snapshot just needs the previous LTS image to be re-tagged and pushed. If the image needs a patch for the new minor LTS snapshot, see the next section. Below, replace `.` with the minor LTS snapshot version. - Check out the `stable` branch of the [Stack repository](https://github.com/commercialhaskell/stack/). - Build and push the images (both standard and `small` variants) using the [build.sh](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/build.sh) script: ~~~text ./build.sh --push lts-. ./build.sh --push --small lts-. ~~~ ## Patch images for new minor LTS snapshot Below, replace `.` with the minor LTS snapshot version. and `.` with the previous minor LTS snapshot version. - Check out the `stable` branch of the [Stack repository](https://github.com/commercialhaskell/stack/). - In `stackage/automated/dockerfiles`, create a new `lts-.` directory. - Create `lts-./Dockerfile`, starting with: ~~~dockerfile FROM $DOCKER_REPO:lts-. ~~~ - Add layers for any changes that need to be made to the image. - Build the new image using the [build.sh](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/build.sh) script: ~~~text ./build.sh lts-. ./build.sh --small lts-. ~~~ - Test the new image. For example, command: ~~~text stack --snapshot=lts-. new image-test cd image-test stack --docker build ~~~ This should use the image you just built. Make sure you test that the new image actually contains the desired changes. - Follow the process in the previous section to push the images. ## Build images for new major LTS snapshot release ### Test a Dockerfile prior to new major LTS snapshot release Replace `` with major version of new LTS snapshot, and `` with previous major LTS snapshot version. - Check out the `stable` branch of the [Stack repository](https://github.com/commercialhaskell/stack/). - In `stackage/automated/dockerfiles`, create a new `lts-.0` directory. - Copy `lts-.0/Dockerfile` to `lts-.0/Dockerfile`. - Check the `FROM` statement, make sure the Ubuntu version matches the Ubuntu version used in the [Stackage Dockerfile](https://github.com/commercialhaskell/stackage/blob/master/Dockerfile). - Update `GHC_VERSION` to match the version used by the [latest nightly snapshot](https://www.stackage.org/nightly). - Set `LTS_SLUG` to the [latest nightly snapshot](https://www.stackage.org/nightly) (this will be temporary until the major LTS snapshot is actually released, at which point it will be updated to `lts-.0`). - Update `PID1_VERSION` and `STACK_VERSION` to the latest versions of those tools. - Make sure `CUDA_VERSION` and `JVM_PATH` match what [debian-bootstrap.sh](https://github.com/commercialhaskell/stackage/blob/master/debian-bootstrap.sh) uses. - Update `LLVM_PATH` to the version required for the GHC version. This will be shown on the download page for the GHC version, which you can reach from https://www.haskell.org/ghc/. It should match the base directory used in `CLANG_PURE_LLVM_INCLUDE_DIR` in [debian-bootstrap.sh](https://github.com/commercialhaskell/stackage/blob/master/debian-bootstrap.sh) (leaving off the `/include` suffix). - Update `BOOTSTRAP_COMMIT` to the Git commit ID of the latest [debian-bootstrap.sh](https://github.com/commercialhaskell/stackage/blob/master/debian-bootstrap.sh). - Check for any other `lts-.*/Dockerfile`s and make sure `lts-.0/Dockerfile` includes anything that was updated in those, if they're still relevant for LTS-15 (note that a newer [debian-bootstrap.sh](https://github.com/commercialhaskell/stackage/blob/master/debian-bootstrap.sh) may already include those changes, so check there first). ### Perform basic tests - Build the image: `docker build -t local/stack-build lts-.0/`. - Ensure that all the directories listed in `PATH`, `CUDA_PATH`, and `CPATH` and any other path-like environment variables actually exist in the image. - Try building a test package with the new image. Command: ~~~text stack --snapshot=nightly new image-test` cd image-test stack --docker --docker-image=local/stack-build build ~~~ This should build without needing to install GHC. - Build the "small" variant. Command: ~~~text docker build -t local/stack-build-small --build-arg "VARIANT=small" lts-.0/ ~~~ - Try building a test package with the new small image. Command: ~~~text stack --snapshot=nightly new small-image-test cd small-image-test stack --docker --docker-image=local/stack-build-small build ~~~ This should build without needing to install GHC. ### Build real image once major LTS snapshot has been released - Update `LTS_SLUG` to `lts-.0` - Update `BOOTSTRAP_COMMIT` to the git commit ID of the latest [debian-bootstrap.sh](https://github.com/commercialhaskell/stackage/blob/master/debian-bootstrap.sh). - Repeat the tests above, except use `lts-.0` instead of `nightly`. - Build and push the real images (both standard and `small` variants) using the [build.sh](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/build.sh) script: ~~~text ./build.sh --push lts-.0 ./build.sh --push --small lts-.0 ~~~ - Commit and push the new Dockerfile to the `stable` branch. stack-3.7.1/doc/maintainers/archive/docker_images.md0000644000000000000000000000254415023557525020651 0ustar0000000000000000
# Docker images Docker Hub includes Docker images under [`fpco/stack-build'](https://hub.docker.com/r/fpco/stack-build). To update those images with a new version of Stack: 1. Under [commercialhaskell/stackage/automated/dockerfiles](https://github.com/commercialhaskell/stackage/tree/master/automated/dockerfiles/), add `lts-X.Y/Dockerfile` (where `X.Y` is the latest Stackage Haskell LTS version), containing (where `X.Z` is the previous Haskell LTS version, and `X.Y.Z` is the newly released Stack version): ~~~dockerfile FROM $DOCKER_REPO:lts-X.Z ARG STACK_VERSION=X.Y.Z RUN wget -qO- https://github.com/commercialhaskell/stack/releases/download/v$STACK_VERSION/stack-$STACK_VERSION-linux-x86_64.tar.gz | tar xz --wildcards --strip-components=1 -C /usr/local/bin '*/stack' ~~~ 2. Run `./build.sh lts-X.Y`. Then test that the new image has the new version of Stack. For example, command: ~~~text docker run --rm fpco/stack-build:lts stack --version ~~~ 3. Use the following commands to push the new image to the registry: ~~~text ./build.sh --push lts-X.Y ./build.sh --push --small lts-X.Y ~~~ stack-3.7.1/doc/maintainers/archive/README.md0000644000000000000000000000024314353310351016771 0ustar0000000000000000# README The `doc/maintainers/archive` directory contains documentation that appears to have been superceded but is preserved in case it is, in fact, useful. stack-3.7.1/doc/maintainers/archive/releases.md0000644000000000000000000002531214651506554017660 0ustar0000000000000000# Archive - from releases.md ## Build Linux static binary distribution with Nix **NOTE: We have switched back to Alpine Linux for building static binaries, done by CI. Leaving this section for future reference.** These instructions are tested on Ubuntu 16.04, but theoretically should work on any Linux distribution. - Install nix (tested with v2.0.4 and v2.1.2, but should work with any) ~~~sh curl https://nixos.org/nix/install | sh ~~~ - Install and authenticate cachix (first two steps at https://cachix.org/ after signing up) - Add nh2's cache: ~~~sh cachix use static-haskell-nix ~~~ !!! note To clear cache index, use `rm $HOME/.cache/nix/binary-cache-v5.sqlite*` (useful if someone else uploads new stuff to the cache and you want to use it right away). The recent `narinfo-cache-positive`/`negative-ttl` options might also help. - Check out Stack commit to be released to `~/stack-release` (or elsewhere, in which case adjust following instructions) - `rm -f ~/stack-release/*.cabal`, to ensure it's regenerated - clone https://github.com/nh2/static-haskell-nix recursively (last known to work with commit 725ceb2479637b3b3ab29298a1bc0e48c54984c9) - in `static-stack` directory, run (from `static-stack/README.md`): ~~~sh $(nix-build --no-link -A run-stack2nix-and-static-build-script --argstr stackDir ~/stack-release) ~~~ - Run integration tests against the static binary [TODO: improve this process by adding full support in `release.hs` or the integration tests for testing a binary built elsewhere] - In `~/stack-release`, run `stack build --flag stack:integration-tests stack:stack-integration-test` - Copy binary built above to place where `stack build` normally puts the `stack binary` (e.g. `cp /nix/store/7vl1xvlbbqjvf864inz5vw7z2z1k4nmw-stack-2.1.0.1/bin/stack /home/vagrant/stack-release/.stack-work/install/x86_64-linux/custom-snapshot-for-building-stack-with-ghc-8.2.2-PyNP5UoO8Ott/8.2.2/bin/stack`; figure it out using `stack exec which stack`) - Run `stack exec stack-integration-test` - Copy the binary built above (in `/nix/store/XXX-stack-X.Y.Z/bin/stack`) to `~/stack-release/_release/bin/stack-X.Y.Z-linux-x86_64/stack` (replace `X.Y.Z` with the version, and the `/nix/store/*` path with that output at the end of the previous command) - Package, sign, and upload to GitHub using Stack's release script in the stack directory: ~~~sh cd ~/stack-release stack etc/scripts/release.hs --no-test-haddocks --binary-variant=static --build-args=--dry-run upload ~~~ (adding `--build-args=--dry-run` ensures the binary you copied will be used rather than building a new one) - Download the bindist from GitHub and double check that the `stack` in it is actually static (use `ldd /path/to/stack`) and that `--version` reports correctly (and not dirty). ## Setting up a Windows VM for releases These instructions are a bit rough, but has the steps to get the Windows machine set up. ## Using Virtualbox 1. Download Virtualbox VM image: https://developer.microsoft.com/en-us/microsoft-edge/tools/vms/mac/ 2. Launch the VM using Virtualbox and the image downloaded 3. Adjust settings: * Number of CPUs: at least half the host's * Memory: at least 3 GB * Video RAM: the minimum recommended by Virtualbox * Enable 3D and 2D accelerated mode (this makes programs with lots of console output much faster) * Enabled shared clipboard (in VM window, Devices->Shared Clipboard->Both Directions) Now continue to the **General Windows setup** subsection below. ## Using ESXi 1. Download the **MSEdge on Win10** VM for **VMWare (Windows, Mac)**. 2. Unzip the file downloaded file 3. Upload the VMDK file to the ESXi datastore 4. SSH into ESXi CLI and run: - `vmkfstools -i /vmfs/volumes/datastore1/win10-msedge/MSEdge-Win10-VMWare-disk1-ORIG.vmdk /vmfs/volumes/datastore1/win10-msedge/MSEdge-Win10-VMWare-disk1.vmdk -d thin`. This converts the disk to a format that is compatible with ESXi. You may have to run `esxcli system module load -m multiextent` first (see https://www.virtuallyghetto.com/2012/09/2gbsparse-disk-format-no-longer-working.html). - `vmkfstools -X 80G /vmfs/volumes/datastore1/win10-msedge/MSEdge-Win10-VMWare-disk1.vmdk`. This makes the disk twice as large, which helps avoid running out of disk space. 5. In the ESXi web UI: - Create a new VM - Give is 8192 MB of memory - Give it 4 virtual CPUs - Remove the default hard disk - Add an **Existing hard disk** - Select `/datastore1/win10-msedge/MSEdge-Win10-VMWare-disk1.vmdk` - Power on the VM - In Windows settings: - Search for "disk management" - Extend the partition to take the whole disk. - In all likelihood, you will want to search for "remote desktop" and enable remote desktop. Then you can connect to the VM using Microsoft Remote Desktop instead of using it from within the ESXi web UI. Now continue to the **General Windows setup** subsection below. ## General Windows setup 5. In **Settings**->**Update & Security**->**Windows Update**->**Advanced options**: * Change **Choose how updates are installed** to **Notify to schedule restart** * Check **Defer upgrades** (this avoids rebooting in the middle of the stack build) 6. In **Settings**->**System**->**Power & sleep** * Disable turning off the screen or going to sleep when plugged in 7. Install msysgit: https://msysgit.github.io/ 8. Install TortoiseHG: https://tortoisehg.bitbucket.io/download/index.html 9. Install nsis-2.46.5-Unicode-setup.exe from http://www.scratchpaper.com/ 10. Install Stack using the Windows 64-bit installer a. Restart any command prompts to ensure they get new `%STACK_ROOT%` value. 11. Visit https://hackage.haskell.org/ in Edge to ensure system has correct CA certificates 13. Run in command prompt: ~~~text md C:\p md C:\tmp cd /d C:\p ~~~ 14. Create `C:\p\env.bat`: ~~~text SET TEMP=C:\tmp SET TMP=C:\tmp SET PATH=C:\Users\IEUser\AppData\Roaming\local\bin;"c:\Program Files\Git\usr\bin";"C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin";%PATH% ~~~ 15. Run `C:\p\env.bat` (do this every time you open a new command prompt) 16. `stack exec -- gpg --import`, and paste in the your GPG secret key (must be done using `stack exec` because that uses the right keyring for the embedded MSYS2 GPG; you can get the key from another machine with `gpg --export-secret-keys --armor `) 17. Run in command prompt (adjust the `user.email` and `user.name` settings): ~~~text git config --global user.email manny@fpcomplete.com git config --global user.name "Emanuel Borsboom" git config --global push.default simple git config --global core.autocrlf true git clone https://github.com/borsboom/stack-installer.git git clone -b stable --reference C:\p\stack-release https://github.com/commercialhaskell/stack.git stack-release cd stack-release stack install cabal-install ~~~ ## Setting up an ARM VM for releases 1. Use Scaleway to start ARMv7 and ARM64 VMs. 2. Select Ubuntu Xenial as the operating system 3. Install the correct version of LLVM: `sudo apt-get install -y llvm-3.9` (appropriate for GHC 8.2, might need different version for other GHCs) 4. Symlink opt-3.X to `opt`: `sudo ln -s opt-3.9 /usr/bin/opt` (adjust the version if you installed a different one above) 5. Switch to gold linker: ~~~sh update-alternatives --install "/usr/bin/ld" "ld" "/usr/bin/ld.gold" 20 update-alternatives --install "/usr/bin/ld" "ld" "/usr/bin/ld.bfd" 10 update-alternatives --config ld ~~~ 6. Add swap space: ~~~sh dd if=/dev/zero of=/swapfile1 bs=1024 count=4194304 mkswap /swapfile1 swapon /swapfile1 echo '/swapfile1 none swap sw 0 0' >>/etc/fstab ~~~ 7. Install additional tools: ~~~Sh apt-get update && apt-get install -y unzip gpg ~~~ 8. Import your GPG key (`gpg --import` and paste the private key) 9. Git settings (adjust for your preferences/email/name) ~~~text git config --global push.default simple git config --global user.email "manny@fpcomplete.com" git config --global user.name "Emanuel Borsboom" ~~~ 10. Install tools used during building and dependencies packages ~~~text sudo apt-get install -y g++ gcc libc6-dev libffi-dev libgmp-dev make xz-utils zlib1g-dev git gnupg ~~~ 11. Install clang+llvm NOTE: the Debian jessie `llvm` package does not work (executables built with it just exit with "schedule: re-entered unsafely."). The version of LLVM needed depends on the version of GHC you need. * GHC 8.2.2 (the standard for building Stack) ~~~sh wget http://llvm.org/releases/3.9.1/clang+llvm-3.9.1-armv7a-linux-gnueabihf.tar.xz && \ sudo tar xvf clang+llvm-3.9.1-armv7a-linux-gnueabihf.tar.xz -C /opt ~~~ Run this now and add it to the `.profile`: ~~~sh export PATH="$HOME/.local/bin:/opt/clang+llvm-3.9.1-armv7a-linux-gnueabihf/bin:$PATH" ~~~ * GHC 7.10.3 ~~~sh wget http://llvm.org/releases/3.5.2/clang+llvm-3.5.2-armv7a-linux-gnueabihf.tar.xz && \ sudo tar xvf clang+llvm-3.5.2-armv7a-linux-gnueabihf.tar.xz -C /opt ~~~ Run this now and add it to the `.profile`: ~~~sh export PATH="$HOME/.local/bin:/opt/clang+llvm-3.5.2-armv7a-linux-gnueabihf/bin:$PATH" ~~~ 12. Install Stack Binary: get an [existing `stack` binary](https://github.com/commercialhaskell/stack/releases) and put it in `~/.local/bin`. From source, using Cabal (the tool): ~~~sh wget http://downloads.haskell.org/~ghc/7.10.3/ghc-7.10.3-armv7-deb8-linux.tar.xz && \ tar xvf ghc-7.10.3-armv7-deb8-linux.tar.xz && \ cd ghc-7.10.3 && \ ./configure --prefix=/opt/ghc-7.10.3 && \ sudo make install && \ cd .. export PATH="/opt/ghc-7.10.3/bin:$PATH" wget https://www.haskell.org/cabal/release/cabal-install-1.24.0.0/cabal-install-1.24.0.0.tar.gz &&&&& \ tar xvf cabal-install-1.24.0.0.tar.gz && \ cd cabal-install-1.24.0.0 && \ EXTRA_CONFIGURE_OPTS="" ./bootstrap.sh && \ cd .. && \ export PATH="$HOME/.cabal/bin:$PATH" && \ cabal update ~~~ Edit `~/.cabal/config`, and set `executable-stripping: False` and `library-stripping: False`. ~~~sh cabal unpack stack && \ cd stack-* && \ cabal install && \ mv ~/.cabal/bin/stack ~/.local/bin ~~~ stack-3.7.1/doc/maintainers/ghc.md0000644000000000000000000001116214646722726015200 0ustar0000000000000000
# Adding a new GHC version * Push new tag to our fork. Command: ~~~text git clone git@github.com:commercialhaskell/ghc.git cd ghc git remote add upstream https://gitlab.haskell.org/ghc/ghc.git git fetch upstream git push origin ghc-X.Y.Z-release ~~~ * [Publish a new GitHub release](https://github.com/commercialhaskell/ghc/releases/new) with tag `ghc-X.Y.Z-release` and same name, with description noting where the binidsts are mirrored from. For example: ~~~text Unless otherwise indicated, bindists are mirrored from https://downloads.haskell.org/~ghc/ * FreeBSD bindists are mirrored from http://distcache.FreeBSD.org/local-distfiles/arrowd/stack-bindists * musl bindists are mirrored from https://github.com/redneb/ghc-alt-libc/releases ~~~ * Download all the relevant GHC bindists from their sources, and upload them to the just-created GitHub release (see [stack-setup-2.yaml](https://github.com/fpco/stackage-content/blob/master/stack/stack-setup-2.yaml) for the ones we used in the last GHC release). In the case of macOS, repackage the `.xz` bindist as a `.bz2`, since macOS does not include `xz` by default or provide an easy way to install it. The script at `etc/scripts/mirror-ghc-bindists-to-github.sh` will help with this. See the comments within the script. * [Edit stack-setup-2.yaml](https://github.com/fpco/stackage-content/edit/master/stack/stack-setup-2.yaml) and add the new bindists, pointing to the GitHub release version. Be sure to update the `content-length` and `sha1` values. Before committing, test using a command like: ~~~text stack --snapshot=ghc-X.Y.Z setup --setup-info-yaml=path/to/stackage-content/stack/stack-setup-2.yaml ~~~ * In [stackage-content](https://github.com/fpco/stackage-content), command: ~~~text cd stack ./update-global-hints.hs ghc-X.Y.Z ~~~ and commit the changes. ## Building GHC **NOTE: We are no longer building custom GHC bindists. This section remains for future reference, but GHC's build system has changed substantially since it was written.** TODO: look into using https://github.com/bgamari/ghc-utils/blob/master/rel-eng/bin-release.sh, which is the script used to official bindists. On systems with a small `/tmp`, you should set TMP and TEMP to an alternate location. Setup the system based on these [instructions](https://gitlab.haskell.org/ghc/ghc/wikis/building/preparation/linux). On Ubuntu (`docker run -ti --rm ubuntu:16.04`): ~~~text apt-get update apt-get install -y ghc alex happy make autoconf g++ git vim xz-utils automake libtool gcc libgmp-dev ncurses-dev libtinfo-dev python3 ~~~ On Void Linux (`docker run -ti --rm voidlinux/voidlinux bash`) command: ~~~text xbps-install -S curl gcc make xz ghc autoconf git vim automake gmp-devel ncurses-devel python3 cabal-install cabal update cabal install alex happy ~~~ For GHC >= 7.10.2, set the `GHC_VERSION` environment variable to the version to build: * `export GHC_VERSION=8.2.2` * `export GHC_VERSION=8.2.1` * `export GHC_VERSION=8.0.2` * `export GHC_VERSION=8.0.1` * `export GHC_VERSION=7.10.3a` * `export GHC_VERSION=7.10.2` then, from [here](https://gitlab.haskell.org/ghc/ghc/wikis/building/quick-start), command: ~~~text git config --global url."git://github.com/ghc/packages-".insteadOf git://github.com/ghc/packages/ git clone -b ghc-${GHC_VERSION}-release --recursive https://gitlab.haskell.org/ghc/ghc.git ghc-${GHC_VERSION} cd ghc-${GHC_VERSION}/ cp mk/build.mk.sample mk/build.mk sed -i 's/^#BuildFlavour *= *perf$/BuildFlavour = perf/' mk/build.mk ./boot ./configure --enable-tarballs-autodownload sed -i 's/^TAR_COMP *= *bzip2$/TAR_COMP = xz/' mk/config.mk make -j$(cat /proc/cpuinfo|grep processor|wc -l) make binary-dist ~~~ GHC 7.8.4 is slightly different.

The `/ -> /README/` redirect ensures that https://docs.haskellstack.org/en/stable/ (for example) will, if not found, redirect to https://docs.haskellstack.org/en/stable/README/. The `/README/ -> /` redirect ensures that https://docs.haskellstack.org/en/latest/README/ (for example) will, if not found, redirect to https://docs.haskellstack.org/en/latest/. MkDocs rendering of `README.md` differed before and after MkDocs 1.0. Prior to MkDocs 1.0, `README.md` rendered to `/README/index.html`. From MkDocs 1.0, `README.md` rendered to `/index.html`. The two redirects above ensure that the Read the Docs flyout works when moving between different versions of the home page using the flyout. Stack moved from MkDocs 0.17.3 to MkDocs 1.3.1 after publishing the documentation for Stack 2.7.5. A configuration file, `.readthedocs.yaml` is included in the repository root directory. See https://docs.readthedocs.io/en/stable/config-file/v2.html. It specifies a Python requirements file in `doc/requirements.txt`. ## MkDocs The `doc/requirements.txt` file pins the version of MkDocs. As at 13 April 2025 it is set to: mkdocs==1.6.0 A configuration file, `mkdocs.yml` is included in the repository root directory. See https://www.mkdocs.org/user-guide/configuration/. `site_dir: _site` specifies the directory where the output HTML and other files are created. This directory is added to the `.gitignore` file. ## Material for MkDocs Stack moved from the default `readthedocs` theme to Material for MkDocs after publishing the documentation for Stack 2.7.5. The new theme has extensive online documentation and features that the default theme lacked. The Material for MkDocs theme is loaded in the `doc/requirements.txt` file: mkdocs-material The theme is specified in the `mkdocs.yml` file: ~~~yaml theme: name: material palette: primary: 'deep purple' accent: 'deep purple' logo: img/stack-logo-white.svg favicon: img/stack-favicon.svg features: - content.code.annotate - content.code.copy - content.code.select - content.tabs.link - navigation.indexes - navigation.tabs - navigation.top ~~~ Read the Docs requires [JQuery](https://jquery.com/) for its JavaScript code to inject the flyout menu. Material for MkDocs does not come with JQuery. So, the following is required in the `mkdocs.yml` file: ~~~yaml extra_javascript: - 'https://code.jquery.com/jquery-3.6.1.min.js' ~~~ The Read the Docs flyout is formatted with a `font-size` that is 90% of the `body` `font-size`. Material for MkDocs has a `body` `font-size` that is `0.5rem`, which is small. A little additional CSS is added to the `extra.css` file, to force the final `font-size` to be `0.7rem`. That size is consistent with that of other elements in the theme. ~~~css body { font-size: 0.777778rem; } ~~~ Material for MkDocs default suggestions for syntax highlighting in code blocks are applied. They are specified in the `mkdocs.yml` file as: ~~~yaml markdown_extensions: - pymdownx.highlight: anchor_linenums: true - pymdownx.inlinehilite - pymdownx.snippets - pymdownx.superfences ~~~ Other extensions to the basic Markdown syntax used include: * Admonitions !!! info This is an example of an 'info' admonition. * Content tabs, which can be nested !!! info Content tabs are used so that users of different operating systems, or different distributions of Linux, can be presented with content specific to their needs. * icons and emojis !!! info The `octicons-tag-24` icon (:octicons-tag-24:) is used to refer to versions of Stack. The `material-cloud-download-outline` icon (:material-cloud-download-outline:) is used to signify a download link. The `octicons-beaker-24` icon (:octicons-beaker-24:) is used with 'Experimental' to signify that a feature is experimental. ## Testing online documentation Online documentation can be tested by establishing a branch on the repository that is then configured on the Read the Docs web site as 'Active' but 'Hidden' - for example branch `mkdocs-test`. As the branch is 'Hidden' it does not appear in the Read the Docs flyout or search results. ## get.haskellstack.org redirects The https://get.haskellstack.org redirects are implemented with [CloudFlare Pages](https://developers.cloudflare.com/pages/platform/redirects/) and a `_redirects` file in the root of the `commercialhaskell/get-haskellstack-org` GitHub [repository](https://github.com/commercialhaskell/get-haskellstack-org). Each redirect is defined as a line in the file with format: ~~~text [source] [destination] ~~~ 'Splats' are used in redirects. On matching, a splat (asterisk, `*`) will greedily match all characters and the matched value can be used in the redirect location with `:splat`. For example, for Stack 2.9.1: ~~~text /stable/* https://github.com/commercialhaskell/stack/releases/download/v2.9.1/stack-2.9.1-:splat /upgrade/linux-x86_64-static.tar.gz https://github.com/commercialhaskell/stack/releases/download/v2.9.1/stack-2.9.1-linux-x86_64.tar.gz /upgrade/* https://github.com/commercialhaskell/stack/releases/download/v2.9.1/stack-2.9.1-:splat / https://raw.githubusercontent.com/commercialhaskell/stack/stable/etc/scripts/get-stack.sh ~~~ stack-3.7.1/doc/maintainers/msys.md0000644000000000000000000001250014445120722015410 0ustar0000000000000000
# Upgrading MSYS2 When installing GHC on Windows, Stack will also install [MSYS2](http://www.msys2.org/). MSYS2 provides a Unix shell and environment, and is necessary for such things as running configure scripts. This section explains the steps required to upgrade the MSYS2 version used by Stack. 1. Download latest installer(s) from MSYS2's website. Historically, there were separate installers for 32 bit (`i686`) and 64 bit (`x86_64`). On 17 May 2020, the MSYS2 project announced it did not plan to release any further `i686` installers. An installer is an executable, versioned by a date in the format YYYYMMDD - for example, `msys2-x86_64-20220503.exe`. 2. Run the installer and install to the default location (`C:\msys64` for the 64 bit version; the location for the 32 bit version was `C:\msys32`). Do not use the installed version; it will create a `.bash_history` file if you do. 3. Create an `.tar.xz` archive file for each relevant directory (eg `C:\msys64`). That is best done using the same `7z` executable in Stack's 'programs' directory (`stack path --programs`) that will be used to extract files from the archive. That can be done in two steps: the first to create a `.tar` archive, and the second to create a `.tar.xz` archive. If the current working directory is Stack's 'programs' directory: ~~~text ./7z a msys2-YYYYMMDD-x86_64.tar C:\msys64 ./7z a msys2-YYYYMMDD-x86_64.tar.xz msys2-YYYYMMDD-x86_64.tar rm msys2-YYYYMMDD-x86_64.tar # Tidy up ~~~ !!! note Previously, the advice was that creating the archive file required a version of [`tar`](https://www.gnu.org/software/tar/tar.html) that supported the compression option `--xz`. The version of `tar` that is supplied with Windows (`C:\Windows\System32\tar.exe`) does not support that option, but MSYS2 can supply a [version](https://packages.msys2.org/package/tar) that does (using its `pacman` tool). Using the existing Stack-supplied MSYS2, in PowerShell and located in a folder with write permissions (so the `.tar.xz` file can be created), it was advised to command: ~~~text stack exec -- pacman -S tar stack exec -- tar cJf msys2-YYYYMMDD-x86_64.tar.xz C:\msys64 ~~~ However, in the case of `msys2-20220503` that resulted in an archive that could not extracted on a terminal that did not have elevated rights ('Run as administrator') due to errors `ERROR: Cannot create symbolic link : A required privilege is not held by the client`. 4. Test that the Stack-supplied `7z` executable can extract the files in the archive that has been created without error: ~~~test ./7z x msys2-YYYYMMDD-x86_64.tar.xz ./7z x msys2-YYYYMMDD-x86_64.tar ~~~ 5. Create a new release tagged and named `msys2-YYYYMMDD` in the `master` branch of the [commercialhaskell/stackage-content](https://github.com/commercialhaskell/stackage-content) GitHub repository, uploading the tarball file(s) into that release. 6. Changes need to be made to the [stackage-content/stack/stack-setup-2.yaml](https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml) file, to switch over to using the newly uploaded files. For example (extract): ~~~yaml # For upgrade instructions, see: https://github.com/commercialhaskell/stack/blob/stable/doc/maintainers/msys.md msys2: windows32: version: "20200517" url: "https://github.com/fpco/stackage-content/releases/download/20200517/msys2-20200517-i686.tar.xz" content-length: 79049224 sha256: 9152ddf50c6bacfae33c1436338235f8db4b10d73aaea63adefd96731fb0bceb windows64: version: "20220503" url: "https://github.com/commercialhaskell/stackage-content/releases/download/msys2-20220503/msys2-20220503-x86_64.tar.xz" content-length: 93835868 sha256: c918f66e984f70add313ee3a5c5b101132cd93d5a3f8e3555e129e2d3dcb3718 ~~~ The `content-length:` key's value is the size of the file in bytes. It can be obtained from the `Length` field of the `dir` command. The `sha256:` key's value can be obtained from the command (in PowerShell): ~~~text (Get-FileHash msys2-YYYYMMDD-x86_64.tar.xz -Algorithm SHA256).Hash.ToLower() ~~~ The `sha256:` key only accepts lowercase hash results as values. 7. The changed `stack-setup-2.yaml` file should be tested locally. This can be done by: * temporarily disabling the existing local copy of MSYS2 by changing the name of the `msys2-YYYYMMDD.installed` file in the `stack path --programs` directory; and * executing the command: ~~~text stack setup --setup-info-yaml ~~~ If all is well, the command should proceed to download the updated version of MSYS2 that has been specified. 8. Raise a pull request on `commercialhaskell/stackage-contents` for the changes to the locally-tested `stack-setup-2.yaml` file. stack-3.7.1/doc/maintainers/releases.md0000644000000000000000000005400114765330073016231 0ustar0000000000000000
# Releases ## Branches * The `release` branch is intended to preserve the most recent release (including, if applicable, Hackage-only dependency compatibility patch releases). * The `stable` branch is intended to be a copy of the `release` branch together with any subsequent commits that (only) revise the documentation for the most recent release. That documentation is presented at . * The `master` branch is the current development branch. It is intended that a working version of Stack can be built from the branch. The release process begins with a copy of the branch. * A `rc/vX.Y` branch (named after a release in the Stack X.Y.* series) is intended to be for release candidates and final releases. It begins as a copy of the `master` branch. ## Pre-release checks 1. Check for any important issues that should be dealt with before release. 2. Check for un-merged pull requests that should be merged before release. 3. Ensure the `release` and `stable` branches are merged to the `master` branch. 4. Check the copyright dates, and update if needed. 5. Check the backwards compatibility section of `CONTRIBUTING.md` is up to date. 6. Ensure CI matrices in docs (travis-complex, appveyor, azure) have current stackage snapshots and GHC versions (e.g. https://github.com/commercialhaskell/stack/pull/4565/files) 7. Update any `stack-*.yaml` that uses a `nightly` snapshot to the latest nightly (go over the extra-deps too) and ensure the project builds and tests pass. For example, command: ~~~text stack build --stack-yaml=… --haddock --test --bench --no-run-benchmarks ~~~ 8. The Windows installer is built using an [NSIS compiler](https://nsis.sourceforge.io/Main_Page). Check that the NSIS compiler that will be used is capable of handling [large strings](https://nsis.sourceforge.io/Special_Builds). 9. Ensure the integration tests pass on Linux, macOS and Windows. 10. Some people prefer, or need, to build Stack with Cabal (the tool). Check that `cabal.project` is up to date (the specified `with-compiler:`). Check that `cabal.config` is up to date and is not missing dependencies relevant on Windows and non-Windows operating systems, following the instructions in `cabal.project`. ## Release preparation ### A: In the `master` branch 1. `package.yaml`: bump to the next release candidate version (bump the second component to the next odd number, ensure the third component is `0`, and add patchlevel `0`; e.g. from `3.4.0` to `3.5.0.0`). !!! attention Be sure to update also `stack.cabal` (for example by using `stack build --dry-run`). 2. `cabal.config`: Ensure the `stack` constraint is set to the same version as in the `package.yaml`. 3. `ChangeLog.md`: Check for any entries that snuck into the previous version's changes due to merges (`git diff origin/stable HEAD ChangeLog.md`) 4. Commit the changes to the `master` branch. ### B: Create a new release candidate branch From the `master` branch, checkout a new release candidate (RC) branch named `rc/vX.Y` (replacing `X.Y` with the first and second components of the release version). ~~~text git checkout -b rc/vX.Y ~~~ ### C: Return to the `master` branch 1. `package.yaml`: bump version to the next unstable version (bump the second component to the next even number, ensure the third component is `0`; e.g. from `3.5.0` to `3.6.0`). !!! attention Be sure to update also `stack.cabal` (for example by using `stack build --dry-run`). 2. `cabal.config`: Ensure the `stack` constraint is set to the same version as in the `package.yaml`. 3. `Changelog.md`: * Change the title of the existing **Unreleased changes** section to what will be the next final (non-RC) release (e.g. `v3.5.1`). * Add new "Unreleased changes" section: ~~~markdown ## Unreleased changes Release notes: **Changes since vX.Y.Z:** Major changes: Behavior changes: Other enhancements: Bug fixes: ~~~ 4. Commit the changes to the `master` branch. ### D: For each release candidate, in the release candidate branch 1. Review documentation for any changes that need to be made: * Ensure all the documentation pages are listed in the `mkdocs.yaml` file. Use `git diff --stat origin/stable..HEAD doc/` to look for new or deleted files. * Any new documentation pages should have the "may not be correct for the released version of Stack" warning at the top. * Search for old Stack version, unstable Stack version, and the next "obvious" possible versions in sequence, and `UNRELEASED` and replace with next release version (`X.Y.1`, where Y is odd). !!! attention Do **NOT** update the repository's issue and pull request templates (in the `.github` directory) to point at the new release version yet! * Search for old snapshots, set to latest snapshot (e.g. in documentation where it references the "currently the latest LTS") * Look for any links to "latest" (`latest/`) documentation, replace with version tag 2. Check for any platform entries that need to be added to (or removed from): * [releases.yaml](https://github.com/fpco/stackage-content/blob/master/stack/releases.yaml), * [install_and_upgrade.md](https://github.com/commercialhaskell/stack/blob/master/doc/install_and_upgrade.md), * [get-stack.sh](https://github.com/commercialhaskell/stack/blob/master/etc/scripts/get-stack.sh), * [doc/README.md](https://github.com/commercialhaskell/stack/blob/master/doc/README.md), and * `get.haskellstack.org` redirects. 3. Re-do the pre-release checks (see the section above). 4. Update `package.yaml` and `ChangeLog.md`. This step differs between a first, second etc release candidate and a final release. === "First RC" * `package.yaml`: bump to first odd patchlevel version (e.g. `X.Y.0.1`). * `ChangeLog.md`: Rename the “Unreleased changes†section to the same version as `package.yaml`, and mark it clearly as a release candidate (e.g. `vX.Y.0.1 (release candidate)`). Remove any empty sections. === "Second, third etc RC" * `package.yaml`: bump to next odd patchlevel version (e.g. `X.Y.0.3`). * `ChangeLog.md`: Rename the “Unreleased changes†section to the same version as `package.yaml`, and mark it clearly as a release candidate (e.g. `vX.Y.0.3 (release candidate)`). Remove any empty sections. === "Final Release" * `package.yaml`: bump version to odd last component and no patchlevel (e.g. from `X.Y.0.2` to `X.Y.1`). * `ChangeLog.md`: consolidate all the release candidate changes into a single section for the final release version. !!! attention After updating `package.yaml`, be sure to update also `stack.cabal` (for example by using `stack build --dry-run`). 5. Ensure the `stack ==` constraint in `cabal.config` is set to be equal to the same version as `package.yaml`. 6. Commit the changes to the release candidate branch. 7. Follow the steps in the *Release process* section below that apply. ## Release process The release process differs between a first, second etc release candidate and a final release. === "First, second etc RC" ### A: Integration tests workflow passes Ensure that the GitHub [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) passes on the branch that you are releasing. This workflow will run automatically for the `rc/*` branch. ### B: Push a Git tag Push a Git tag. The tag should be `rc/vX.Y.Z.A`, with `X.Y.Z.A` matching the version in `package.yaml`. For example, command: ~~~text git tag -m rc/vX.Y.Z.A rc/vX.Y.Z.A git push origin rc/vX.Y.Z.A ~~~ ### C: Edit the draft GitHub release, and publish it Wait for the GitHub [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) to complete for the branch you just created. This will create a draft GitHub release and upload the bindists (plus signatures and hashes) to it. Edit the draft [GitHub release](https://github.com/commercialhaskell/stack/releases/): * Add `(release candidate)` to the name field and ensure that *This is a pre-release* is checked. * Add the ChangeLog to the description. Publish the GitHub release. ### D: Consider adding other platforms to the GitHub release The [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) is limited to the platforms supported by the GitHub-hosted runners (currently, x86_64 and macOS/AArch64) and any self-hosted runners (currently, only Linux/AArch64). However, it is possible to edit the GitHub release to include binary distributions for other platforms. The prerequisites are: * a computer with that platform (operating system, machine architecture); * a sufficiently-recent existing version of Stack for that platform; * a tool to print SHA checksums, such as `shasum` on Linux and macOS; and * the GNU Privacy Guard tool (`gpg`), which has had imported the private key used to sign Stack executables (see further below). The steps are similar to those in the workflow: 1. Change to the root directory of the Stack project. 2. `stack etc/scripts/release.hs check`, to check before building. 3. `stack etc/scripts/release.hs build`, to build. The output 'assets' (`stack--- ...`) will be in the `_release` directory in the root directory of the Stack project. 4. For each of the output assets, create a corresponding SHA 256 file with a `.sha256` extension. For example (where `` is the name of the file): ~~~text shasum -a 256 > .sha256 ~~~ 5. For each of the output assets, create a corresponding ASCII-armored signature file with an `.asc` extension using `gpg`. For example (where `` is the name of the file): ~~~text gpg --digest-algo=sha512 --detach-sig --armor -u 0x575159689BEFB442 ~~~ 6. Edit the GitHub release to include the output assets and their corresponding `.sha256` and `.asc` files. The private key used to sign Stack executables can be exported from a version of `gpg` to which it has previously been imported with: ~~~text gpg --armor --export-secret-key 0x575159689BEFB442 ~~~ The private key, so obtained, can be imported into `gpg` by: 1. Commanding `gpg --import`. 2. Pasting the private key. 3. Entering Ctrl+D and Enter. ### E: Update versions and `ChangeLog.md` for 'unreleased' In the `rc/vX.Y` branch: * `package.yaml`: bump the version number. Bump the fourth component to an even number (e.g. from `3.5.0.1` to `3.5.0.2`). !!! attention Be sure to update also `stack.cabal` (for example by using `stack build --dry-run`). * `cabal.config`: Ensure the `stack` constraint is set to the same version as in the `package.yaml`. * `ChangeLog.md`: Add an “Unreleased changes†section (update the “changes since†version): ~~~markdown ## Unreleased changes Release notes: **Changes since vX.Y.Z:** Major changes: Behavior changes: Other enhancements: Bug fixes: ~~~ ### F: Request update of GHCup's metadata Raise a pull request at the [`haskell/ghcup-metadata`](https://github.com/haskell/ghcup-metadata) GitHub repository to request an addition to GHCup's latest metadata configuration file for prereleases, tagged as the latest prerelease. In the metadata, change the tags for any past Stack prereleases to indicate that they are no longer the latest prerelease. ### G: Announce the release candidate Announce the release candidate: * on the [Haskell Community](https://discourse.haskell.org/c/announcements/10/l/latest) forum; * in the Haskell Foundation's [general](https://matrix.to/#/#haskell-foundation-general:matrix.org) room (address `#haskell-foundation-general:matrix.org`) on [Matrix](https://matrix.org/); * in the Haskell [Stack and Stackage](https://matrix.to/#/#haskell-stack:matrix.org) room (address `#haskell-stack:matrix.org`) on [Matrix](https://matrix.org/); and * in Reddit's [Haskell](https://www.reddit.com/r/haskell/) community. In each case, use the subject (change 'first' to 'second' etc for subsequent release candidates): * `[ANN] First release candidate for Stack X.Y.Z` In the message, include: * a link to the release on GitHub (`https://github.com/commercialhaskell/stack/releases/tag/rc/vX.Y.Z.A`) to download it * the release description from Github. === "Final Release" ### A: Integration tests workflow passes Ensure that the GitHub [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) passes on the branch that you are releasing. This workflow will run automatically for `rc/*` branches. ### B: Push a Git tag Push a Git tag. The tag should be `vX.Y.Z`, where `X.Y.Z` matches the version in `package.yaml`. For example, command: ~~~text git tag -m vX.Y.Z vX.Y.Z git push origin vX.Y.Z ~~~ ### C: Edit the draft GitHub release, and publish it Wait for the GitHub [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) to complete for the tag you just created. This will create a draft GitHub release and upload the bindists (plus signatures and hashes) to it. Edit the draft [GitHub release](https://github.com/commercialhaskell/stack/releases/): * Add the ChangeLog to the description. * Get the list of contributors to the release and add it to the description. For example, command: === "Unix-like" ~~~text git shortlog -s origin/release..HEAD|sed 's/^[0-9 \t]*/* /'|LC_ALL=C sort -f ~~~ === "Windows" ~~~text (git shortlog -s origin/release..HEAD) -Replace '^[0-9 \t]*', '* ' | Sort-Object ~~~ in PowerShell. Publish the GitHub release. ### D: Consider adding other platforms to the GitHub release The [Integration Tests workflow](https://github.com/commercialhaskell/stack/actions?query=workflow%3A%22Integration+tests%22) is limited to the platforms supported by the GitHub-hosted runners (currently, x86_64 and macOS/AArch64) and any self-hosted runners (currently, only Linux/AArch64). However, it is possible to edit the GitHub release to include binary distributions for other platforms. The prerequisites are: * a computer with that platform (operating system, machine architecture); * a sufficiently-recent existing version of Stack for that platform; * a tool to print SHA checksums, such as `shasum` on Linux and macOS; and * the GNU Privacy Guard tool (`gpg`), which has had imported the private key used to sign Stack executables (see further below). The steps are similar to those in the workflow: 1. Change to the root directory of the Stack project. 2. `stack etc/scripts/release.hs check`, to check before building. 3. `stack etc/scripts/release.hs build`, to build. The output 'assets' (`stack--- ...`) will be in the `_release` directory in the root directory of the Stack project. 4. For each of the output assets, create a corresponding SHA 256 file with a `.sha256` extension. For example (where `` is the name of the file): ~~~text shasum -a 256 > .sha256 ~~~ 5. For each of the output assets, create a corresponding ASCII-armored signature file with an `.asc` extension using `gpg`. For example (where `` is the name of the file): ~~~text gpg --digest-algo=sha512 --detach-sig --armor -u 0x575159689BEFB442 ~~~ 6. Edit the GitHub release to include the output assets and their corresponding `.sha256` and `.asc` files. The private key used to sign Stack executables can be exported from a version of `gpg` to which it has previously been imported with: ~~~text gpg --armor --export-secret-key 0x575159689BEFB442 ~~~ The private key, so obtained, can be imported into `gpg` by: 1. Commanding `gpg --import`. 2. Pasting the private key. 3. Entering Ctrl+D and Enter. ### E: Upload to Hackage and reset branches Upload the `stack` package to Hackage with the command: ~~~text stack upload . --pvp-bounds=lower ~~~ Reset the `release` branch to the released commit. For example, with the commands: ~~~text git checkout release git merge --ff-only vX.Y.Z git push origin release ~~~ Update the `stable` branch to the released commit. For example, with the commands: ~~~text git checkout stable git merge --ff-only vX.Y.Z git push origin stable ~~~ Merge any changes made in the RC, `release` or `stable` branches to the `master` branch. Be careful about version and `ChangeLog.md`. It is best to do this by making a `ci/merge-stable-to-master` branch and waiting for CI to pass, then merging. If anything is complicated to merge, consider making it a pull request and getting it reviewed rather than merging immediately. Delete the RC branch, both locally and on the remote. For example with the commands: ~~~text git branch -d rc/vX.Y git push origin :rc/vX.Y ~~~ ### F: Activate the version on Read The Docs Activate the version for new release tag, on [readthedocs.org](https://readthedocs.org/projects/stack/versions/). Ensure that the `stable` documentation has updated. ### G: Update get.haskellstack.org redirects Update the https://get.haskellstack.org redirects by updating the `_redirects` file in the root of the `commercialhaskell/get-haskellstack-org` GitHub [repository](https://github.com/commercialhaskell/get-haskellstack-org). For further information, see the [get.haskellstack.org redirects](haskellstack.org.md#gethaskellstackorg-redirects) documentation. Test with the commands: === "Unix-like" ~~~text curl -vL https://get.haskellstack.org/stable/linux-x86_64.tar.gz >/dev/null curl -vL https://get.haskellstack.org/upgrade/linux-x86_64.tar.gz >/dev/null ~~~ === "Windows" ~~~text curl -vL https://get.haskellstack.org/stable/linux-x86_64.tar.gz >NUL curl -vL https://get.haskellstack.org/upgrade/linux-x86_64.tar.gz >NUL ~~~ and make sure it redirects to the new version. ### H: Update versions and `ChangeLog.md` for 'unreleased' In the `stable` branch: * `package.yaml`: bump the version number. Bump the third component to an even number (e.g. from `3.5.1` to `3.5.2`). !!! attention Be sure to update also `stack.cabal` (for example by using `stack build --dry-run`). * `cabal.config`: Ensure the `stack` constraint is set to the same version as in the `package.yaml`. ### I: Update the repository's issue and pull request templates The repository's issue and pull request templates are the `.github` directory. Update them to refer to the new release version (`X.Y.Z`). ### J: Request update of GHCup's metadata Raise a pull request at the [`haskell/ghcup-metadata`](https://github.com/haskell/ghcup-metadata) GitHub repository to request an addition to GHCup's latest metadata configuration files for releases and 'vanilla' releases, tagged as the latest release. (The GHCup project will decide whether, and when, to recommend the release.) In the metadata, change the tags for any past Stack releases to indicate that they are no longer the latest release. ### K: Announce the release Announce the release: * on the [Haskell Community](https://discourse.haskell.org/c/announcements/10/l/latest) forum. * in the Haskell Foundation's [general](https://matrix.to/#/#haskell-foundation-general:matrix.org) room (address `#haskell-foundation-general:matrix.org`) on [Matrix](https://matrix.org/). * in the Haskell [Stack and Stackage](https://matrix.to/#/#haskell-stack:matrix.org) room (address `#haskell-stack:matrix.org`) on [Matrix](https://matrix.org/). * in Reddit's [Haskell](https://www.reddit.com/r/haskell/) community. In each case, use the subject: * `[ANN] Stack X.Y.Z` In the message, include: * the release description from Github. stack-3.7.1/doc/maintainers/self-hosted_runners.md0000644000000000000000000001077014765330073020424 0ustar0000000000000000
# Self-hosted runners [GitHub Actions](https://docs.github.com/en/actions) is used to do CI on Stack. In the case of the Linux/AArch64 platform, since 8 February 2025, that is done with a GitHub-hosted runner (currently in public preview). Previously, that was done in a separate `linux-arm64` job of the `integration-tests.yml` workflow that ran on a self-hosted runner for Linux and ARM64. Given that the GitHub-hosted runner is only in preview, the documentation of the self-hosted runner is being preserved for the time being. ## Introduction The current basic setup was: * FP Complete has an Oracle Cloud account that provides a free tier that includes a really powerful ARM64 machine; * within Oracle Cloud, FP Complete are running an Ubuntu/ARM64 instance; and * on that instance, FP Complete are running the GitHub Runner software. The runner name is `stack-github-action3` and the machine name is `stack-github-action3`. Occasionally Oracle will turn off the machine because: * Oracle thinks it is not being used (because of the free tier); and/or * other things, like disk space filling up. The disk space can fill up due to obsolete Docker images, versions of GHC installed by Stack or obsolete snapshots created by Stack. ## Managing the `stack-github-action3` runner With the appropriate authority installed on the server, a maintainer can manage the runner remotely using SSH, with command `ssh ubuntu@arm-runner.stackage.org`. !!! info The authority is the addition of the maintainer's SSH public key to the end of file `~/.ssh/authorized_keys` on the server. This is best done using [`tmux`](https://github.com/tmux/tmux/wiki), a terminal multiplexer, as follows: ~~~sh $ # In a shell, command tmux to create a new session with a single window with a $ # single pane (a pseudo terminal). The session will be displayed on the screen $ # by a client: $ tmux new-session $ # Send the following command to that pseudo terminal, to connect to the $ # remote host: $ ssh ubuntu@arm-runner.stackage.org $ # In the remote host, change to the actions-runner directory: $ cd actions-runner $ # In the remote host, start the runner: $ ./run.sh $ # Detach the current client from the session by the key combination of $ # 'C-b' 'd' (where 'C-b' is CTRL+b). The session will continue to run in the $ # background: $ C-b d ~~~ The available disk space can be queried with command `df -h`; the relevant entry is for filesystem `/dev/sda1`. If the available space is low, that may be due to unncessary GHC versions installed in Stack's `programs` directory. ## Re-configuring a removed `stack-github-action3` runner A self-hosted runner is automatically removed from GitHub if it has not connected to GitHub Actions for more than 14 days. Re-adding a self-hosted runner to GitHub requires it to be configured, and GitHub will suggest a configuration command like: ~~~text ./config.sh --url https://github.com/commercialhaskell/stack --token ~~~ However, to re-use and configure the runner machine, you have first to delete the `.runner` file inside the `actions-runner` directory. This allows the runner to be registered without having to re-download the self-hosted runner application. ## The `ghc-arm-5` runner From 9 February 2024, the Haskell Foundation sought to provide an alternative runner named `ghc-arm-5` but that was based on NixOS and proved to be incompatible. ## Alternatives to the self-hosted runners One alternative to the self-hosted runners is to build statically-linked Stack executables for Linux/AArch64 on macOS/AArch64. This can be done thanks to the multi-architecture Docker images built and published by Olivier Benz, at https://gitlab.com/benz0li/ghc-musl. GitHub provides a GitHub-hosted macOS/AArch64 runner (`macOS-14`). Unfortunately, that is macOS/M1 and the M1 machine architecture does not support nested virtualisation. This rules out using Docker, as the runner is itself a virtual machine. However, this solution can be applied locally and the build outputs for the Linux/AArch64 platform added manually to the result of the GitHub workflow. The experimental Haskell script `etc/scripts/release-linux-aarch64.hs` is intended to facilitate the building of statically-linked Stack executables for Linux/AArch64 on macOS/AArch64. stack-3.7.1/doc/maintainers/stack_errors.md0000644000000000000000000005456315023557531017142 0ustar0000000000000000
## Stack's errors In connection with considering Stack's support of the [Haskell Error Index](https://errors.haskell.org/) initiative, this page seeks to take stock of the errors that Stack itself can raise, by reference to the `master` branch of the Stack repository. Last updated: 2025-05-12. * `Stack.main`: catches exceptions from action `commandLineHandler`. - `ExitCode` - `throwIO` * `Stack.main`: catches exceptions from action `run`: - `ExitCode` (`exitWith`) - `PrettyException` (`exitFailure`) - `SomeException` (`exitFailure`) The following types are instances of `Control.Exception.Exception` and `Show`.

# Stack Maintainer Team Process ## Purpose of this document This guide is intended to formalize the process by which the `Stack` maintainer team operates. We expect it'll evolve over time as experience makes clearer what works best in practice. Having a well-documented set of processes and responsibilities has been instrumental in effectively maintaining the `Stackage` project across a distributed team ([see the `Stackage` curators' guide ](https://github.com/commercialhaskell/stackage/blob/master/CURATORS.md)) and we hope to replicate that success here. ## Goals The goals of the `Stack` maintainer team are to: - Ensure that incoming bug reports and feature requests are properly triaged, answered, and/or escalated. - Provide timely review of, and feedback on, incoming pull requests. - Set up clear channels of communication for users to make support requests. - Keep Stack up-to-date with its upstream dependencies, including new GHC and Cabal releases, and libraries Stack depends on. - Increase the [bus factor](https://en.wikipedia.org/wiki/Bus_factor) of the project, encouraging more people to contribute heavily to the codebase and take ownership of it. - Make it easy to improve the documentation and test coverage of the project. The sections below detail various activities by the `Stack` team to realize these goals. ## Issue triage The maintainer team provides ongoing review and responses to newly-filed GitHub issues and pull requests. From experience, we find it's easiest to have a single person "on call" at any given time. Therefore, the team rotates shifts on a weekly basis. The "on call" triager is responsible for: - Reviewing incoming issues and pull requests on GitHub. - Answering questions he/she is able to. - Merging PRs he/she feels comfortable reviewing. - Closing out irrelevant/misplaced issues. - Pulling in another maintainer to assist if necessary. The goal of the triager role is to facilitate continual, smooth progress of `Stack`'s development and to provide triagers an opportunity to become more familiar with how the project runs. This is one path to getting a lot of experience with the codebase, plus great interaction with the rest of the maintainer team, without necessarily taking on major coding tasks. ## Time commitment Someone considering joining the issue triager team may be wondering: > "How large of a time investment is necessary?" That’s a great question for anyone considering taking on this role. It’s frankly somewhat uncertain right now since we’re only getting started, but we can venture a reasonable guess: We currently average about one new issue per day. Assuming that each issue entails roughly ten-to-fifteen minutes of total interaction on the part of the triager (before passing it off to someone else, answering a support question, etc) that amounts to about one or two hours spent per week being on-call. Again, these estimates will evolve over time as we settle into an optimal process, but for now we anticipate growing the team to about eight members (which is the size of the `Stackage` team as well), each of whom is likely to spend about two hours in total on upkeep work every eight weeks. ## Issue and pull request interaction guidelines These guidelines apply to all members of the maintainer team. - Be courteous. - Avoid leaving issues and PRs in an ambiguous state. By default, when you respond to an issue/PR, you’re taking responsibility for shepherding it to completion. Be explicit if you’re passing it to someone else, or asking the submitter for more info/updates/etc. - Use labels, assignees, and milestones wherever possible. - If you know you’ll be unable to answer for a significant period of time, say so. Even better: ask someone else to take over from you. ## Assessing feature requests and enhancement PRs **NB: this section is very likely to evolve over time as well.** A frequent source of new GitHub issues is users who would like to propose some enhancement and/or change to how `Stack` currently operates. Some of these are both small and obviously beneficial, in which case the triager should feel empowered to "green light" the idea if it makes sense to do so. If the proposal is already in the form of an actionable PR the triager may review and merge at their discretion. Oftentimes though, the request is larger and more far-reaching in nature. Perhaps the requester is unaware of the extent to which his or her change would impact other people's workflows or related components in the code. Conversely, they may have a deep understanding of its implications and feel strongly that it would be a valuable improvement, whereas it's not so clear to the triager. Discerning which requests should be considered "small" and which warrant broader collaboration is admittedly an inexact science. Use your best judgment and don't sweat the occasional mistake if you approve something you thought was small but ultimately wasn't. In the case of medium-to-large sized feature requests, it's best to solicit feedback from at least one or two of the core `Stack` developers. You may use GitHub @mentions to draw the relevant contributors' attention to the issue in question. If you're not sure who's best to consult you should ask on `#stack-collaborators`. Try to be clear to the requester that you're opening the discussion up to more participants and that the proposal will require thoughtful consideration (probably a majority vote) before any decision is made. Also remember that busy schedules, lack of complete familiarity with a given subject, strong-yet-opposing opinions held by equally rational people, and many other factors often collude to halt forward progress in arriving at firm conclusions in such situations... If at all possible, try to keep things on-track and concrete. *Regardless of feature size, bear in mind that sometimes the best answer is a respectful "no".* *If feasible, propose alternative solutions or educate the user in preference to complicating `Stack` or accepting scope-creep.* With respect to assessing a PR's code, @snoyberg has outlined some [tips for successfully getting one's work merged ](https://www.snoyman.com/blog/2017/06/how-to-send-me-a-pull-request) into his projects which may be helpful to `Stack` triagers when performing reviews, as well. ## Real-time communications At present, the maintainer team mostly communicates via a rather quiet channel called [`#stack-collaborators`](../CONTRIBUTING.md#slack-channel) in the Haskell Foundation's Slack workspace, although we may migrate to some other platform in the future. ## Dealing with support issues We encourage users to submit support requests via GitHub issues and try to consolidate our efforts in addressing questions there. Other platforms, such as Reddit, StackOverflow, et al, may be helpful as well but the `Stack` maintainers team makes no guarantees about regularly checking them. *We may decide to offload support questions elsewhere in the future, but for now the most important thing is to direct users to a single destination.* ## Issue vs pull request Sometimes it is ambiguous whether something should be opened as an issue to discuss a change, versus a pull request including the change. A guiding principle here is: if it will take longer to open an issue than a PR, open the PR. As an extreme example: if you have a small documentation typo correction, open a PR, it will _definitely_ take less time than opening an issue and describing the change you'd like to make. This logic can sometimes apply to minor code changes. Use your best judgement. ## Issue closing policy We need to strike a balance in issue handling between keeping a maintainable set of issues—thereby making the lives of maintainers, contributors, and users easier—and allowing legitimate issues to remain open. The end goal of this is: any open issue indicates "this deserves attention in the near future." Before this policy existed, issues actually meant "maybe someone will deal with this someday." The policy for closing an issue depends entirely on the type of issue we're looking at. When closing an issue, please provide a brief explanation for why the issue was closed, such as a reference to a PR, a comment about lack of clarification, etc. !!! note The following sections establish rules under which a bug report will be closed by the maintainer team. The goal is to avoid a situation where issues linger in an indeterminate state. The maintainer team is allowed to disregard these "rules" at any point. In other words: the goal isn't to allow people to "lawyer" issues. ### Discussion Some issues are for discussing the project. These issues should start with a clear question, have an owner, and be closed when either: * The original question has been answered * There is no clear question or owner * No progress has been made in 30 days Discussions are typically opened by maintainers and contributors. ### Support Support questions are requests for assistance in using Stack. They must have a clear set of steps followed by the user and a desired outcome. Support requests sometimes overlap with bug reports, handled next. Support requests are closed when: * The user decides their question is answered * No clarification to questions from the Stack team is given for 30 days * The question is determined out of scope by the Stack team ### Bug report A bug report describes a misbehavior in Stack itself. There are some cases where an issue may appear somewhere between a support request and a bug report. The Stack team will determine which category an issue falls into. Bug reports must include clear reproduction steps, an expected outcome, and an actual outcome. Bug reports are closed when: * The bug is fixed on the `master` or `stable` branch (NOTE: we do not wait for fixes to be released before closing issues) * The Stack team is unable to reproduce the issue * No clarification to questions from the Stack team is given for 30 days * The bug is determined to be out of scope by the Stack team, such as being an upstream issue ### Feature request Feature requests are usually clear, but sometimes have overlap with one of the above topics. Determination of an issue being a feature request will be made by the Stack team. Features are closed when: * The feature is implemented on the `master` or `stable` branch * The Stack team decides that the feature is not desired in the project * If no one offers to implement the feature for 30 days Note that, to account for the last bullet, we have a [Wishlist](https://github.com/commercialhaskell/stack/wiki/Wishlist) wiki page. We recommend closing issues with a message such as the following: > Closing due to lack of implementation progress in the past 30 days. We > attempt to keep the Stack issue tracker focused on active work items. If you > are still interested in this feature and would like to see it implemented in > the future, please add it to the > [Wishlist](https://github.com/commercialhaskell/stack/wiki/Wishlist) Wiki page. stack-3.7.1/doc/maintainers/version_scheme.md0000644000000000000000000000424114765341452017443 0ustar0000000000000000
# Version scheme A Stack package or executable may have a version with three or four components: `X.Y.Z` or `X.Y.Z.A`. ## Development or stable versions * Versions with an _even_ `Y` component are development versions (the `master` branch) * Versions with an _odd_ `Y` component are stable versions (the `stable` branch, or in a `rc/vX.Y` release candidate branch for not-yet-released versions) ## Unreleased or released versions * Versions with an _even_ `Z` component are unreleased versions (including release candidates) * Versions with an _odd_ `Z` component are released versions * Except for the `release` branch, all branches must have an even `Z` component * Except for the `release`, `stable` and `rc/vX.Y` release candidate branches, all branches will have a `0` `Z` component ## Use of a fourth component * Release candidate binaries will be released with an odd `A` component * Hackage-only dependency compatibility patch releases add a `A` component (e.g. `v2.5.1.1`, in the `release` branch) * Pre-release unstable binaries will be released with the date as the `A` component (e.g. `3.6.0.20241228`) ## Examples * `3.5.0.0`: `v3.5.*` series pre-release branch (`rc/v3.5` branch) * `3.5.0.1`: first release candidate for first release of `v3.5.*` series (`rc/v3.5` branch) * `3.5.0.2`: continuing development on pre-release branch * `3.5.0.3`: second release candidate for first release of `v3.5.*` series (`rc/v3.5` branch) * `3.5.1`: first release of the `3.5.*` series (`release` branch) * `3.5.2.1`: first release candidate for second release of `3.5.*` series (`rc/v3.5` branch) * `3.5.3`: second release of `3.5.*` series (`release` branch) * `3.5.3.1`: first Hackage-only patch of `3.5.3` (`release` branch) * `3.5.3.2`: second Hackage-only patch of `3.5.3` (`release` branch) * `3.6.0`: unstable development code (`master` branch) * `3.6.0.20241228`: pre-release snapshot of unstable version (`master` branch) stack-3.7.1/doc/other_resources.md0000644000000000000000000000264414734007300015323 0ustar0000000000000000

# The Haskell Tool Stack Welcome to the [Haskell](https://www.haskell.org/) programming language and the Haskell Tool Stack (Stack)! Stack is a program for developing Haskell projects. It is aimed at new and experienced users of Haskell and seeks to support them fully on Linux, macOS and Windows. Haskell code is compiled by the [Glasgow Haskell Compiler](https://www.haskell.org/ghc/) (GHC), which can also be used interactively. Stack features include: * Installing GHC automatically. * Installing packages needed for your project. * Building your project. * Testing your project. * Benchmarking your project. * Using GHC interactively. Stack is used at the command line. You will need terminal software for your system (which will likely come with its operating system) and a program to edit code files. There are a number of freely-available and popular code editors that have Haskell extensions. ## How to install Stack Stack can be installed on most Unix-like operating systems (including macOS) and Windows. It will require at least about 5 GB of disk space, for use with one version of GHC. Stack can be installed directly or by using the GHCup tool. === "Directly" Stack can be installed directly on various operating systems. === "Linux" For most Linux distributions, on x86_64 or AArch64 machine architectures, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions in the guide to [setting up](install_and_upgrade.md). === "macOS" From late 2020, Apple began a transition from Mac computers with Intel processors (Intel-based Mac) to [Mac computers with Apple silicon](https://support.apple.com/en-gb/HT211814). === "Intel-based" For most Intel-based Mac computers, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions in the guide to [setting up](install_and_upgrade.md). === "Apple silicon" Mac computers with Apple silicon have an M series chip. These chips use an architecture known as ARM64 or AArch64. For Mac computers with Apple silicon, the easiest way to install Stack is to command either: ~~~text curl -sSL https://get.haskellstack.org/ | sh ~~~ or: ~~~text wget -qO- https://get.haskellstack.org/ | sh ~~~ These commands download a script file and run it using `sh`. ??? question "Will the installation script need root access?" The script at [get.haskellstack.org](https://get.haskellstack.org/) will ask for root access using `sudo`. It needs such access in order to use your platform's package manager to install dependencies and to install to `/usr/local/bin`. If you prefer more control, follow the manual installation instructions in the guide to [setting up](install_and_upgrade.md). === "Windows" Most machines using the Windows operating system have a x86_64 architecture. More recently, Microsoft has provided Windows on Arm that runs on other processors. === "x86_64" On 64-bit Windows, the easiest way to install Stack is to download and install the [Windows installer](https://get.haskellstack.org/stable/windows-x86_64-installer.exe). !!! info By default, the Windows installer will set the [Stack root](topics/stack_root.md) to `C:\sr`. !!! note Systems with antivirus software may need to add Stack to the list of 'trusted' applications. ??? warning "I have a Windows username with a space in it" GHC 9.4.1 and later have a bug which means they do not work if the path to the `ghc` executable has a space character in it. The default location for Stack's 'programs' directory will have a space in the path if the value of the `USERNAME` environment variable includes a space. A solution is to configure Stack to use a different location for its 'programs' directory. For further information, see the [`local-programs-path`](configure/yaml/non-project.md#local-programs-path) non-project specific configuration option documentation. === "Windows on Arm" The GHC project does not yet provide a version of GHC that runs on Windows on Arm. === "Other/direct downloads" For other operating systems and direct downloads see the guide to [setting up](install_and_upgrade.md). === "GHCup" The separate [GHCup](https://www.haskell.org/ghcup/) project provides a tool that can be used to install Stack and other Haskell-related tools, including GHC and [Haskell Language Server](https://github.com/haskell/haskell-language-server) (HLS). HLS is a program that is used by Haskell extensions for popular code editors. GHCup provides Stack for some combinations of machine architecture and operating system not provided elsewhere. By default, the script to install GHCup (which can be run more than once) also configures Stack so that if Stack needs a version of GHC, GHCup takes over obtaining and installing that version. ??? question "How do I upgrade Stack?" Follow the advice under [setting up](install_and_upgrade.md#upgrade-stack). ??? question "How do I remove Stack?" For information about how to uninstall Stack, command: ~~~text stack uninstall ~~~ To uninstall Stack, it should be sufficient to delete: 1. the Stack root directory (see `stack path --stack-root`, before you uninstall); 2. if different, the directory containing Stack's global configuration file (see `stack path --global-config`, before you uninstall); 3. on Windows, the directory containing Stack's tools (see `stack path --programs`, before you uninstall), which is usually located outside of the Stack root directory; and 4. the `stack` executable file (see `which stack`, on Unix-like operating systems, or `where.exe stack`, on Windows). You may also want to delete ``.stack-work`` directories in any Haskell projects that you have built using Stack. ## Quick Start guide Once Stack is installed, you can get an immediate experience of using it to build an executable with Haskell. ### Step 1: Start your new project A complex project can have more than one package and each package can have more than one executable (program). However, to start a new single-package project named `my-project`, issue these four commands in a terminal (click :material-plus-circle: to learn more about each command): ~~~shell stack new my-project # (1)! cd my-project # (2)! stack build # (3)! stack exec my-project-exe # (4)! ~~~ 1. Create a new directory named `my-project`. It contains all the files needed to start a project correctly, using a default template. 2. Change the current working directory to `my-project`. 3. Build the template project and create an executable named `my-project-exe`. First, if necessary, Stack will download a version of GHC in an isolated location. That won't interfere with other GHC installations on your system. (On Windows, if necessary, Stack will also download [MSYS2](https://www.msys2.org/). MSYS2 is a project that provides popular tools for developers on Windows.) 4. Run (execute) the built executable, in Stack's environment. For a complete list of Stack's commands, and flags and options common to those commands, simply command: ~~~text stack ~~~ For help on a particular Stack command, including flags and options specific to that command, for example `stack build`, command: ~~~text stack build --help ~~~ If you want to launch a run-eval-print loop (REPL) environment, then command: ~~~shell stack repl # (1)! ~~~ 1. `stack ghci` can be used instead of `stack repl`. GHCi is GHC's REPL tool. People organise Haskell code into packages. If you want to use Stack to install an executable provided by a Haskell package, then all you have to do is command: ~~~text stack install ~~~ ### Step 2: Next steps The `stack new my-project` command in step one should have created the following files and directories, among others. Click :material-plus-circle: to learn more about each file: ~~~shell . ├── app │   └── Main.hs # (1)! ├── src │   └── Lib.hs # (2)! ├── test │ └── Spec.hs # (3)! ├── my-project.cabal # (4)! ├── package.yaml # (5)! └── stack.yaml # (6)! ~~~ 1. The Haskell source code for the executable (application). As your project develops you can add further source code files to the `app` directory. 2. The executable uses a library. The Haskell source code for the library. As your project develops you can add further source code files to the `src` directory. 3. The package has a test suite executable. The Haskell source code for the test suite. As your project develops you can add further source code files to the `test` directory. 4. A file describing the package in the Cabal format, including other packages on which depends. Stack generates it from the contents of the `package.yaml` file. If the `package.yaml` file is deleted, Stack will use the Cabal file. 5. A file describing the package in the Hpack format. Stack generates the `my-project.cabal` file from its contents. If you want, you can delete the file and update the Cabal file directly. As your project develops, you may need to depend on a library provided by another Haskell package. If you do, add the name of that new package to the `dependencies:` section. 6. Stack's project-level configuration. This specifies a snapshot that, in turn, specifies a version of GHC and a set of package versions chosen to work well together. It also identifies the local packages in the project. If you add a new package as a dependency in the package description, and Stack reports that the Stack configuration has no specified version for it, then follow Stack's likely recommended action to add a specific version to the `extra-deps:` section. That was a really fast introduction on how to start to code in Haskell using Stack. If you want to go further, we recommend you read Stack's guide to [getting started](tutorial/index.md). ## Complete guide to Stack A complete guide to Stack is available, covering the most common ways to [use Stack](tutorial/index.md), its [commands](commands/index.md), its [configuration](configure/index.md), specific [topics](topics/index.md), and [frequently asked questions](faq.md). Terms used in Stack's documentation are also explained in the [glossary](glossary.md). ## Why Stack? Stack has a strong focus on plans for building that are reproducible; projects that have more than one package; and a consistent, easy-to-learn set of Stack commands. It also aims to provide the ability to customise and power that experienced developers need. Stack does not stand alone. It is built on the great work provided by:

# Azure CI This page documents how to use Stack on [Azure CI](http://dev.azure.com/). ## Quick Start Note that you have to create [azure pipelines](#creating-azure-pipelines) for your project and then you need to put the relevant configuration files: * For simple Azure configuration, copy-paste the [azure-simple](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-simple.yml) file into `azure-pipelines.yml`. * For complex Azure configuration, you need to take the below linked four files and put all of them into the `.azure` directory. For a more detailed explanation, you can read further. ## Simple and Complex configuration We provide two fully baked configuration ready to be used on your projects: * [The simple Azure configuration](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-simple.yml) is intended for applications that do not require multiple GHC support or cross-platform support. It builds and tests your project with just the settings present in your `stack.yaml` file. * The complex Azure configuration is intended for projects that need to support multiple GHC versions and multiple operating systems, such as open source libraries to be released to Hackage. It tests against Stack for different snapshots on Linux, macOS and Windows. These are the files for the complex configuration: - [azure-pipelines.yml](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-pipelines.yml) : This is the starter file used by the Azure CI. - [azure-linux-template.yml](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-linux-template.yml) : Template for Azure Linux build - [azure-osx-template.yml](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-osx-template.yml) : Template for Azure macOS build - [azure-windows-template.yml](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/azure/azure-windows-template.yml) : Template for Azure Windows build !!! note It is likely going to be necessary to modify this configuration to match the needs of your project, such as tweaking the build matrix to alter which GHC versions you test against, or to specify GHC-version-specific `stack.yaml` files if necessary. Don't be surprised if it doesn't work the first time around. See the multiple GHC section below for more information. ## Creating Azure Pipelines Each of these configurations is ready to be used immediately. But before we go into where to put them, we have to create pipeline for your project in Azure CI platform: * Go to [dev.azure.com](https://dev.azure.com). You have to initially sign-in to your microsoft account there. * Once you have logged in to your Microsoft account, you have to sign in to [Azure devops](https://user-images.githubusercontent.com/737477/52465678-70963080-2ba5-11e9-83d8-84112b140236.png) from there. * You will be greeted with a [dashboard](https://user-images.githubusercontent.com/737477/52465677-70963080-2ba5-11e9-904a-c15c7c0524ef.png) where you can create your projects. * Click the "Create Project" button and fill the relevant information in the [dialog](https://user-images.githubusercontent.com/737477/52465676-70963080-2ba5-11e9-82a4-093ee58f11c9.png) and then click the "Create" button. * This will lead you to the project [dashboard](https://user-images.githubusercontent.com/737477/52465675-6ffd9a00-2ba5-11e9-917e-3dec251fcc87.png) page where you can create pipelines. * Click on "Pipelines" in the left menu. This will load the [pipelines page](https://user-images.githubusercontent.com/737477/52465673-6ffd9a00-2ba5-11e9-97a4-04e703ae1fbc.png) on the right. * Click on the button "New Pipeline" and you have to follow through the wizard there. You need to choose your github repository (or Azure repos) and follow the wizard. Note that in the [Configure step](https://user-images.githubusercontent.com/737477/52465670-6ffd9a00-2ba5-11e9-83a3-9fffdacbf249.png) you have to select the "Starter Pipeline". This will open up an [editor window](https://user-images.githubusercontent.com/737477/52465669-6f650380-2ba5-11e9-9662-e9c6fc2682b5.png). You can leave the existing YAML configuration there as it is and click the "Save and run" button. That will popup a [dialog](https://user-images.githubusercontent.com/737477/52465668-6f650380-2ba5-11e9-9203-6347a609e3c4.png). Select the relevant option and click "Save and run" button. (Note that this step would have created `azure-pipelines.yml` in your repository. You have to replace that with the appropriate configuration file.) The rest of this document explains the details of common Azure configurations for those of you who want to tweak the above configuration files or write your own. *Note:* both Azure and Stack infrastructures are actively developed. We try to document best practices at the moment. ## Infrastructure Note that you need at least one agent to build your code. You can specify which virtual image you want to choose using this configuration: ~~~yaml pool: vmImage: ubuntu-latest ~~~ The other popular options are `macOS-latest`, `windows-latest` for macOS and Windows respectively. You can find the [complete list](https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/hosted?view=vsts&tabs=yaml) here. You also have the option to select a specific supported ubuntu version like `ubuntu-18.08`. ## Installing Stack Currently there is only one reasonable way to install Stack: fetch a precompiled binary from GitHub. ~~~yaml - script: | mkdir -p ~/.local/bin curl -L https://get.haskellstack.org/stable/linux-x86_64.tar.gz | tar xz --wildcards --strip-components=1 -C ~/.local/bin '*/stack' displayName: Install Stack ~~~ ## Installing GHC There are two ways to install GHC: - Let Stack download GHC - Install GHC using apt package manger. This method is only applicable for Debian based images. But we only use the first method of using Stack to download GHC. ### Multiple GHC - parametrised builds For different GHC versions, you probably want to use different project-level configuration files (`stack.yaml`, by default). If you don't want to put a specific `stack.yaml` for a particular snapshot and still want to test it, you have specify your snapshot argument in `ARGS` environment variable (you will see an example below). ~~~yaml strategy: matrix: GHC 8.0: ARGS: "--snapshot lts-9" GHC 8.2: ARGS: "--snapshot lts-11" GHC 8.4: ARGS: "--snapshot lts-12" GHC 8.6: ARGS: "--snapshot lts-14" GHC 8.8: ARGS: "--snapsht lts-15" nightly: ARGS: "--snapshot nightly" ~~~ ## Running tests After the environment setup, actual test running is simple. Command: ~~~text stack $ARGS test --bench --no-run-benchmarks --haddock --no-haddock-deps ~~~ ## Other details Some Stack commands will run for long time. To avoid timeouts, use the [timeoutInMinutes](https://docs.microsoft.com/en-us/azure/devops/pipelines/process/phases?tabs=yaml&view=azdevops#timeouts) for jobs. ## Examples - [commercialhaskell/stack](https://github.com/commercialhaskell/stack/blob/master/azure-pipelines.yml) - [psibi/tldr-hs](http://github.com/psibi/tldr-hs) - [psibi/wai-slack-middleware](https://github.com/psibi/wai-slack-middleware) stack-3.7.1/doc/topics/CI.md0000644000000000000000000000107014651506554013711 0ustar0000000000000000
# Continuous integration (CI) ## GitHub Actions The Stack repository uses GitHub Actions for its own CI. For further information, see the guide to [contributing](../CONTRIBUTING.md#continuous-integration-ci). ## Azure For further information, see the [Azure CI](azure_ci.md) documentation. ## Travis For further information, see the [Travis CI](travis_ci.md) documentation. stack-3.7.1/doc/topics/custom_snapshot.md0000644000000000000000000001020015023557531016635 0ustar0000000000000000
## Snapshot specification [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) Snapshots provide a list of packages to use, along with flags, GHC options, and a few other settings. Snapshots may extend any other snapshot that can be specified in a [`snapshot`](../configure/yaml/project.md#snapshot) or [`resolver`](../configure/yaml/project.md#resolver) key. The packages specified follow the same syntax for dependencies in Stack's project-level configuration files. Unlike the `extra-deps` key, however, no support for local directories is available in snapshots to ensure reproducibility. !!! info Stack uses the [Pantry](https://hackage.haskell.org/package/pantry) library for snapshot specification. ~~~yaml snapshot: lts-23.24 # Inherits GHC version and package set compiler: ghc-9.8.3 # Overwrites GHC version in the snapshot, optional # Additional packages, follows extra-deps syntax packages: - unordered-containers-0.2.7.1 - hashable-1.2.4.0 - text-1.2.2.1 # Packages from the parent snapshot to ignore drop-packages: - wai-extra # Packages which should be hidden hidden: wai: true warp: false # Set GHC options for specific packages ghc-options: warp: - -O2 # Override flags, can also override flags in the parent snapshot flags: unordered-containers: debug: true ~~~ If you put this in a `snapshot.yaml` file in the same directory as your project, you can now use the snapshot like this: ~~~yaml snapshot: snapshot.yaml ~~~ This is an example of a custom snapshot stored in the filesystem. They are assumed to be mutable, so you are free to modify it. We detect that the snapshot has changed by hashing the contents of the involved files, and using it to identify the snapshot internally. It is often reasonably efficient to modify a custom snapshot, due to Stack sharing snapshot packages whenever possible. ### Overriding the compiler The following snapshot specification will be identical to `lts-23.24`, but instead use `ghc-9.8.3` instead of `ghc-9.8.4`: ~~~yaml snapshot: lts-23.24 compiler: ghc-9.8.3 ~~~ ### Dropping packages The following snapshot specification will be identical to `lts-23.24`, but without the `text` package in our snapshot. Removing this package will cause all the packages that depend on `text` to be unbuildable, but they will still be present in the snapshot. ~~~yaml snapshot: lts-23.24 drop-packages: - text ~~~ ### Hiding packages The following snapshot specification will be identical to `lts-23.24`, but the `text` package will be hidden when registering. This will affect, for example, the import parser in the script command. ~~~yaml snapshot: lts-23.24 hidden: - text ~~~ ### Specifying GHC options In order to specify GHC options for a package, you use the same syntax as the [ghc-options](../configure/yaml/non-project.md#ghc-options) key for build configuration. The following snapshot specification will be identical to `lts-23.24`, but provides `-O1` as a ghc-option for `text`: ~~~yaml snapshot: lts-23.24 packages: - text-2.0.2 ghc-options: text: -O1 ~~~ This works somewhat differently than the stack.yaml `ghc-options` key, in that options can only be specified for packages that are mentioned in the custom snapshot's `packages` list. It sets the ghc-options, rather than extending those specified in the snapshot being extended. Another difference is that the `*` entry for `ghc-options` applies to all packages in the `packages` list, rather than all packages in the snapshot. ### Specifying Cabal flags In order to specify Cabal flags for a package, you use the same syntax as the [flags](../configure/yaml/project.md#flags) key for build configuration. The following snapshot specification will be identical to `lts-23.24`, but it enables the `developer` Cabal flag: ~~~yaml snapshot: lts-23.24 packages: - text-2.0.2 flags: text: developer: true ~~~ stack-3.7.1/doc/topics/debugging.md0000644000000000000000000001043414765341733015357 0ustar0000000000000000
# Debugging To profile a component of the current project, pass the [`--profile` flag](../commands/build_command.md#-profile-flag) to `stack build`. The flag: * for project packages, turns on the Cabal flag [`--enable-profiling`](https://cabal.readthedocs.io/en/stable/setup-commands.html#cmdoption-runhaskell-Setup.hs-configure-enable-profiling); * turns on the Cabal flag [`--enable-library-profiling`](https://cabal.readthedocs.io/en/stable/setup-commands.html#cmdoption-runhaskell-Setup.hs-configure-enable-library-profiling); and * passes GHC's [`+RTS -p` runtime options](https://downloads.haskell.org/ghc/latest/docs/users_guide/profiling.html#rts-flag--p) to any test suites and benchmarks. For example the following command will build the `my-tests` testsuite with profiling options and create a `my-tests.prof` file in the current directory as a result of the test run. ~~~text stack test --profile my-tests ~~~ The `my-tests.prof` file now contains time and allocation info for the test run. To create a profiling report for an executable, e.g. `my-exe`, you can command: ~~~text stack exec --profile -- my-exe +RTS -p ~~~ For more fine-grained control of compilation options there are the [`--library-profiling` flag](../commands/build_command.md#-no-library-profiling-flag) and [`--executable-profiling` flag](../commands/build_command.md#-no-executable-profiling-flag). The `--library-profiling` flag: * turns on the Cabal flag [`--enable-library-profiling`](https://cabal.readthedocs.io/en/stable/setup-commands.html#cmdoption-runhaskell-Setup.hs-configure-enable-library-profiling); and * passes GHC's [`+RTS -p` runtime options](https://downloads.haskell.org/ghc/latest/docs/users_guide/profiling.html#rts-flag--p) to any test suites and benchmarks. The `--executable-profiling` flag: * for project packages, turns on the Cabal flag [`--enable-profiling`](https://cabal.readthedocs.io/en/stable/setup-commands.html#cmdoption-runhaskell-Setup.hs-configure-enable-profiling); * turns on the Cabal flag [`--enable-library-profiling`](https://cabal.readthedocs.io/en/stable/setup-commands.html#cmdoption-runhaskell-Setup.hs-configure-enable-library-profiling); and * passes GHC's [`+RTS -p` runtime options](https://downloads.haskell.org/ghc/latest/docs/users_guide/profiling.html#rts-flag--p) to any test suites and benchmarks. To enable compilation with profiling options by default you can add the following to a project-level or global configuration file: ~~~yaml build: library-profiling: true executable-profiling: true ~~~ ## Further reading For more commands and uses, see the [official GHC chapter on profiling](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/profiling.html), the [Haskell wiki](https://wiki.haskell.org/How_to_profile_a_Haskell_program), and the [chapter on profiling in Real World Haskell](http://book.realworldhaskell.org/read/profiling-and-optimization.html). ## Tracing To generate a backtrace in case of exceptions during a test or benchmarks run, use the `--trace` flag. Like `--profile` this compiles with profiling options, but adds the `+RTS -xc` runtime option. ## Debugging symbols Building with debugging symbols in the [DWARF information](https://ghc.haskell.org/trac/ghc/wiki/DWARF) is supported by Stack. This can be done by passing the flag `--ghc-options="-g"` and also to override the default behaviour of stripping executables of debugging symbols by passing either one of the following flags: `--no-strip`, `--no-library-stripping` or `--no-executable-stripping`. In Windows, GDB can be installed to debug an executable with `stack exec -- pacman -S gdb`. Windows' Visual Studio compiler's debugging format PDB is not supported at the moment. This might be possible by [separating](https://stackoverflow.com/questions/866721/how-to-generate-gcc-debug-symbol-outside-the-build-target) debugging symbols and [converting](https://github.com/rainers/cv2pdb) their format. Or as an option when [using the LLVM backend](http://blog.llvm.org/2017/08/llvm-on-windows-now-supports-pdb-debug.html). stack-3.7.1/doc/topics/developing_on_windows.md0000644000000000000000000001266614651506631020031 0ustar0000000000000000
# Developing on Windows # On Windows, Stack comes with an installation of [MSYS2](https://www.msys2.org/). An environment of MSYS2 (by default, `MINGW64` on 64-bit Windows or `MINGW32` on 32-bit Windows) will be used by Stack to provide a Unix-like shell and environment for Stack. This may be necessary for installing some Haskell packages, such as those which use `configure` scripts, or if your project needs some additional tools during the build phase. No matter which terminal software you choose (Windows Terminal, Console Windows Host, Command Prompt, PowerShell, Git bash or any other) you can use this environment too by executing all programs through `stack exec -- `. Executables and libraries can be installed with the MSYS2 package manager `pacman`. All tools can be found in the [index](https://packages.msys2.org) to MSYS2 packages. A [guide](https://www.msys2.org/docs/package-management/) to package management with `pacman` is also available. `pacman` — like all other tools in the Stack environment — should be started with `stack exec -- pacman`. Help about `pacman` commands (operations) can be obtained by `stack exec -- pacman --help`. Help about a specific `pacman` operation can be obtained by using `--help` (or `-h`) with an operation. For example, help about the operation `--sync` (or `-S`) can be obtained with `stack exec -- pacman --sync --help` or, equivalently, `stack exec -- pacman -Sh`. Command `stack path --bin-path` to see the PATH in the Stack environment. If the relevant MSYS2 environment is `MINGW64`, on Windows, it includes the `\mingw64\bin`, `\usr\bin` and `\usr\local\bin` directories of the Stack-supplied MSYS2. (It includes the corresponding directory if the relevant MSYS2 environment is other than `MINGW64`.) If your executable depends on files (for example, dynamic-link libraries) in those directories and you want to run it outside of the Stack environment, you will need to ensure copies of those files are on the PATH. Command `stack path --extra-include-dirs` and `stack path --extra-library-dirs` to see the extra directories searched for C header files or system libraries files in the Stack environment. If the relevant MSYS2 environment is `MINGW64`, on Windows, it includes the `\mingw64\include` (include) and the `\mingw64\lib` and `\mingw64\bin` directories (library) of the Stack-supplied MSYS2. (It includes the corresponding directories if the relevant MSYS2 environment is other than `MINGW64`.) For further information about configuring the relevant MSYS2 environment, see Stack's [`msys-environment`](../configure/yaml/non-project.md#msys-environment) non-project specific configuration option documentation. ## Updating the Stack-supplied MSYS2 ## The Stack-supplied MSYS2 can itself be updated with the Stack-supplied `pacman`. See the MSYS2 guide [Updating MSYS2](https://www.msys2.org/docs/updating/). If the Stack-supplied `pacman` has a version that is 5.0.1.6403 or greater (see `stack exec -- pacman --version`) then the command to update is simply: stack exec -- pacman -Suy This command may need to be run more than once, until everything is reported by `pacman` as 'up to date' and 'nothing to do'. ## Setup.hs ## `Setup.hs` is automatically run inside the Stack environment. So when you need to launch another tool you don't need to prefix the command with `stack exec --` within the custom `Setup.hs` file. ## Pacman packages to install for common Haskell packages ## The following lists MSYS2 packages known to allow the installation of some common Haskell packages on Windows. Feel free to submit additional entries via a pull request. * For [text-icu](https://hackage.haskell.org/package/text-icu) install `mingw64/mingw-w64-x86_64-icu`. * For [zlib >= 0.7](https://hackage.haskell.org/package/zlib) the default Cabal flag `pkg-config` is `true` and requires executable `pkg-config` on the PATH. MSYS2 [defaults](https://www.msys2.org/docs/pkgconfig/) to [`pkgconf`](https://packages.msys2.org/package/pkgconf?repo=msys&variant=x86_64) as its `pkg-config` implementation. Installation: stack exec -- pacman -S pkgconf Alternatively, build with `--flag zlib:-pkg-config`. ## CMake ## CMake has trouble finding other tools even if they are available on the PATH. Likely this is not a CMake problem but one of the environment not fully integrating. For example GHC comes with a copy of GCC which is not installed by MSYS2 itself. If you want to use this GCC you can provide a full path to it, or find it first with `System.Directory.findExecutable` if you want to launch GCC from a Haskell file such as `Setup.hs`. Experience tells that the `mingw-w64` versions of Make and CMake are most likely to work. Though there are other versions available through `pacman`, so have a look to see what works for you. Both tools can be installed with the commands: stack exec -- pacman -S mingw-w64-x86_64-make stack exec -- pacman -S mingw-w64-x86_64-cmake Even though Make and CMake are then both installed into the same environment, CMake still seems to have trouble to find Make. To help CMake find GCC and Make supply the following flags: -DCMAKE_C_COMPILER=path -DCMAKE_MAKE_PROGRAM=path stack-3.7.1/doc/topics/docker_integration.md0000644000000000000000000005277114651506554017306 0ustar0000000000000000
Docker integration =============================================================================== Stack has support for automatically performing builds inside a Docker container, using volume mounts and user ID switching to make it mostly seamless. FP Complete provides images for use with stack that include GHC, tools, and optionally have all of the Stackage LTS packages pre-installed in the global package database. The primary purpose for using stack/docker this way is for teams to ensure all developers are building in an exactly consistent environment without team members needing to deal with Docker themselves. See the [how stack can use Docker under the hood](https://www.fpcomplete.com/blog/2015/08/stack-docker) blog post for more information about the motivation and implementation of stack's Docker support. If you'd like to build Docker images that contain your Haskell executables, see [Building Haskell Apps with Docker](https://www.fpcomplete.com/blog/2017/12/building-haskell-apps-with-docker). Prerequisites ------------------------------------------------------------------------------- ### Supported operating systems **Linux 64-bit**: Docker use requires machine (virtual or metal) running a Linux distribution [that Docker supports](https://docs.docker.com/installation/#installation), with a 64-bit kernel. If you do not already have one, we suggest Ubuntu 14.04 ("trusty") since this is what we test with. **macOS**: [Docker for Mac](https://docs.docker.com/docker-for-mac/) is the supported way to use Docker integration on macOS (the older Docker Machine (boot2docker) approach to using Docker on macOS is not supported due to issues with host volume mounting that make Stack nearly unusable for anything but the most trivial projects). Other Un*xen are not officially supported but there are ways to get them working. See [#194](https://github.com/commercialhaskell/stack/issues/194) for details and workarounds. Note: you may want to use set the `mount-mode` option to `delegated`, since this can dramatically improve performance on macOS (see [configuration](#configuration) for more information). **Windows does not work at all** (see [#2421](https://github.com/commercialhaskell/stack/issues/2421)). ### Docker Install the latest version of Docker by following the [instructions for your operating system](http://docs.docker.com/installation/). The Docker client should be able to connect to the Docker daemon as a non-root user. For example (from [here](http://docs.docker.com/installation/ubuntulinux/#ubuntu-raring-1304-and-saucy-1310-64-bit)): # Add the connected user "${USER}" to the docker group. # Change the user name to match your preferred user. sudo gpasswd -a ${USER} docker # Restart the Docker daemon. sudo service docker restart You will now need to log out and log in again for the group addition to take effect. Note the above has security implications. See [security](#security) for more. Usage ------------------------------------------------------------------------------- This section assumes that you already have Docker installed and working. If not, see the [prerequisites](#prerequisites) section. If you run into any trouble, see the [troubleshooting](#troubleshooting) section. ### Enable in stack.yaml The most basic configuration is to add this to your project's `stack.yaml`: docker: enable: true See [configuration](#configuration) for additional options. You can enable it on the command-line using `stack --docker`. Please note that in a docker-enabled configuration, stack uses the GHC installed in the Docker container by default. To use a compiler installed by stack, add system-ghc: false (see [`system-ghc`](../configure/yaml/non-project.md#system-ghc)). ### Use stack as normal With Docker enabled, most stack sub-commands will automatically launch themselves in an ephemeral Docker container (the container is deleted as soon as the command completes). The project directory and `~/.stack` are volume-mounted into the container, so any build artifacts are "permanent" (not deleted with the container). The first time you run a command with a new image, you will be prompted to run `stack docker pull` to pull the image first. This will pull a Docker image with a tag that matches your snapshot. Only LTS snapshots are supported (we do not generate images for nightly snapshots). Not every LTS version is guaranteed to have an image existing, and new LTS images tend to lag behind the LTS snapshot being published on stackage.org. Be warned: these images are rather large! Docker sub-commands ------------------------------------------------------------------------------- These `stack docker` sub-commands have Docker-specific functionality. Most other `stack` commands will also use a Docker container under the surface if Docker is enabled. ### pull - Pull latest version of image `stack docker pull` pulls an image from the Docker registry for the first time, or updates the image by pulling the latest version. ### reset - Reset the Docker "sandbox" In order to preserve the contents of the in-container home directory between runs, a special "sandbox" directory is volume-mounted into the container. `stack docker reset` will reset that sandbox to its defaults. Note: `~/.stack` is separately volume-mounted, and is left alone during reset. Command-line options ------------------------------------------------------------------------------- The default Docker configuration can be overridden on the command-line. See `stack --docker-help` for a list of all Docker options, and consult [configuration](#configuration) section below for more information about their meanings. These are global options, and apply to all commands (not just `stack docker` sub-commands). Configuration ------------------------------------------------------------------------------- `stack.yaml` contains a `docker:` section with Docker settings. If this section is omitted, Docker containers will not be used. These settings can be included in project, user, or global configuration. Here is an annotated configuration file. The default values are shown unless otherwise noted. docker: # Set to false to disable using Docker. In the project configuration, # the presence of a `docker:` section implies docker is enabled unless # `enable: false` is set. In user and global configuration, this is not # the case. enable: true # The name of the repository to pull the image from. See the "repositories" # section of this document for more information about available repositories. # If this includes a tag (e.g. "my/image:tag"), that tagged image will be # used. Without a tag specified, the LTS version slug is added automatically. # Either `repo` or `image` may be specified, but not both. repo: "fpco/stack-build" # Exact Docker image name or ID. Overrides `repo`. Either `repo` or `image` # may be specified, but not both. (default none) image: "5c624ec1d63f" # Registry requires login. A login will be requested before attempting to # pull. registry-login: false # Username to log into the registry. (default none) registry-username: "myuser" # Password to log into the registry. (default none) registry-password: "SETME" # If true, the image will be pulled from the registry automatically, without # needing to run `stack docker pull`. See the "security" section of this # document for implications of enabling this. auto-pull: true # If true, the container will be run "detached" (in the background). Refer # to the Docker users guide for information about how to manage containers. # This option would rarely make sense in the configuration file, but can be # useful on the command-line. When true, implies `persist`. detach: false # If true, the container will not be deleted after it terminates. Refer to # the Docker users guide for information about how to manage containers. This # option would rarely make sense in the configuration file, but can be # useful on the command-line. `detach` implies `persist`. persist: false # What to name the Docker container. Only useful with `detach` or # `persist` true. (default none) container-name: "example-name" # Sets the network used by docker. Gets directly passed to dockers `net` # argument (default: host) network: host # Additional arguments to pass to `docker run`. (default none) run-args: ["--net=bridge"] # Directories from the host to volume-mount into the container. If it # contains a `:`, the part before the `:` is the directory on the host and # the part after the `:` is where it should be mounted in the container. # (default none, aside from the project and stack root directories which are # always mounted) mount: - "/foo/bar" - "/baz:/tmp/quux" # Sets the volume mount mode, passed directly to `docker`. # The default mode (consistent) is safest, but may suffer poor performance # on non-Linux platforms such as macOS, where the `delegated` mode will # be significantly faster. # See https://docs.docker.com/docker-for-mac/osxfs-caching/ # for valid values and the implications of changing the default. mount-mode: delegated # Environment variables to set in the container. Environment variables # are not automatically inherited from the host, so if you need any specific # variables, use the `--docker-env` command-line argument version of this to # pass them in. (default none) env: - "FOO=BAR" - "BAR=BAZ QUUX" # Location of a Docker container-compatible 'stack' executable with the # matching version. This executable must be compatible with the Docker # image in terms of platform (linux-x86_64) and shared libraries # (statically linked is best, otherwise the image needs to have the # same shared libraries installed). # Valid values are: # host: use the host's executable. This is the default when the host's # executable is known to work (e.g., from official linux-x86_64 bindist) # download: download a compatible executable matching the host's version. # This is the default when the host's executable is not known to work # image: use the 'stack' executable baked into the image. The version # must match the host's version # /path/to/stack: path on the host's local filesystem stack-exe: host # If true (the default when using the local Docker Engine), run processes # in the Docker container as the same UID/GID as the host. The ensures # that files written by the container are owned by you on the host. # When the Docker Engine is remote (accessed by tcp), defaults to false. set-user: true # Require the version of the Docker client to be within the specified # Cabal-style version range (e.g., ">= 1.6.0 && < 1.9.0") require-docker-version: "any" Image Repositories ------------------------------------------------------------------------------- FP Complete provides the following public image repositories on Docker Hub: - [fpco/stack-build](https://registry.hub.docker.com/r/fpco/stack-build/) (the default) - GHC (patched), tools (Stack, Cabal (the tool), happy, alex, etc.), and system developer libraries required to build all Stackage packages. FP Complete also builds custom variants of these images for their clients. These images can also be used directly with `docker run` and provide a complete Haskell build environment. In addition, most Docker images that contain the basics for running GHC can be used with Stack's Docker integration. For example, the [official Haskell image repository](https://hub.docker.com/_/haskell/) works. See [Custom images](#custom-images) for more details. Security ------------------------------------------------------------------------------- Having `docker` usable as a non-root user is always a security risk, and will allow root access to your system. It is also possible to craft a `stack.yaml` that will run arbitrary commands in an arbitrary docker container through that vector, thus a `stack.yaml` could cause stack to run arbitrary commands as root. While this is a risk, it is not really a greater risk than is posed by the docker permissions in the first place (for example, if you ever run an unknown shell script or executable, or ever compile an unknown Haskell package that uses Template Haskell, you are at equal risk). Nevertheless, there are [plans to close the stack.yaml loophole](https://github.com/commercialhaskell/stack/issues/260). One way to mitigate this risk is, instead of allowing `docker` to run as non-root, replace `docker` with a wrapper script that uses `sudo` to run the real Docker client as root. This way you will at least be prompted for your root password. As [@gregwebs](https://github.com/gregwebs) pointed out, put this script named `docker` in your PATH (and make sure you remove your user from the `docker` group as well, if you added it earlier): #!/bin/bash -e # The goal of this script is to maintain the security privileges of sudo # Without having to constantly type "sudo" exec sudo /usr/bin/docker "$@" Additional notes ------------------------------------------------------------------------------- ### Volume-mounts and ephemeral containers Since filesystem changes outside of the volume-mounted project directory are not persisted across runs, this means that if you `stack exec sudo apt-get install some-ubuntu-package`, that package will be installed but then the container it's installed in will disappear, thus causing it to have no effect. If you wish to make this kind of change permanent, see later instructions for how to create a [derivative Docker image](#derivative-image). Inside the container, your home directory is a special location that volume- mounted from within your project directory's `.stack-work` in such a way as that installed GHC/cabal packages are not shared between different Stackage snapshots. In addition, `~/.stack` is volume-mounted from the host. ### Network stack containers use the host's network stack within the container by default, meaning a process running in the container can connect to services running on the host, and a server process run within the container can be accessed from the host without needing to explicitly publish its port. To run the container with an isolated network, use `--docker-run-args` to pass the `--net` argument to `docker-run`. For example: stack --docker-run-args='--net=bridge --publish=3000:3000' \ exec some-server will run the container's network in "bridge" mode (which is Docker's default) and publish port 3000. ### Persistent container If you do want to do all your work, including editing, in the container, it might be better to use a persistent container in which you can install Ubuntu packages. You could get that by running something like `stack --docker-container-name=NAME --docker-persist exec bash`. This means when the container exits, it won't be deleted. You can then restart it using `docker start -a -i NAME`. It's also possible to detach from a container while it continues running in the background using by pressing Ctrl-P Ctrl-Q, and then reattach to it using `docker attach NAME`. Note that each time you run `stack --docker-persist`, a _new_ persistent container is created (it will not automatically reuse the previous one). See the [Docker user guide](https://docs.docker.com/userguide/) for more information about managing Docker containers. ### Derivative image Creating your own custom derivative image can be useful if you need to install additional Ubuntu packages or make other changes to the operating system. Here is an example (replace `stack-build:custom` if you prefer a different name for your derived container, but it's best if the repo name matches what you're deriving from, only with a different tag, to avoid recompilation): ;;; On host $ sudo stack --docker-persist --docker-container-name=temp exec bash ;;; In container, make changes to OS # apt-get install r-cran-numderiv [...] # exit ;;; On host again $ docker commit temp stack-build:custom $ docker rm temp Now you have a new Docker image named `stack-build:custom`. To use the new image, run a command such as the following or update the corresponding values in your `stack.yaml`: stack --docker-image=stack-build:custom Note, however, that any time a new image is used, you will have to re-do this process. You could also use a Dockerfile to make this reusable. Consult the [Docker user guide](https://docs.docker.com/userguide/) for more on creating Docker images. ### Custom images The easiest way to create your own custom image us by extending FP Complete's images, but if you prefer to start from scratch, most images that include the basics for building code with GHC will work. The image doesn't even, strictly speaking, need to include GHC, but it does need to have libraries and tools that GHC requires (e.g., libgmp, gcc, etc.). There are also a few ways to set up images that tightens the integration: * Create a user and group named `stack`, and create a `~/.stack` directory for it. Any build plans and caches from it will be copied from the image by Stack, meaning they don't need to be downloaded separately. * Any packages in GHC's global package database will be available. This can be used to add private libraries to the image, or the make available a set of packages from an LTS release. Troubleshooting ------------------------------------------------------------------------------- ### "No Space Left on Device", but 'df' shows plenty of disk space This is likely due to the storage driver Docker is using, in combination with the large size and number of files in these images. Use `docker info|grep 'Storage Driver'` to determine the current storage driver. We recommend using either the `overlay` or `aufs` storage driver for stack, as they are least likely to give you trouble. On Ubuntu, `aufs` is the default for new installations, but older installations sometimes used `devicemapper`. The `devicemapper` storage driver's doesn't work well with large filesystems, and we have experienced other instabilities with it as well. We recommend against its use. The `btrfs` storage driver has problems running out of metadata space long before running out of actual disk space, which requires rebalancing or adding more metadata space. See [CoreOS's btrfs troubleshooting page](https://coreos.com/docs/cluster-management/debugging/btrfs-troubleshooting/) for details about how to do this. Pass the `-s ` argument to the Docker daemon to set the storage driver (in `/etc/default/docker` on Ubuntu). See [Docker daemon storage-driver option](https://docs.docker.com/reference/commandline/cli/#daemon-storage-driver-option) for more details. You may also be running out of inodes on your filesystem. Use `df -i` to check for this condition. Unfortunately, the number of inodes is set when creating the filesystem, so fixing this requires reformatting and passing the `-N` argument to mkfs.ext4. ### Name resolution doesn't work from within container On Ubuntu 12.04, by default `NetworkManager` runs `dnsmasq` service, which sets `127.0.0.1` as your DNS server. Since Docker containers cannot access this dnsmasq, Docker falls back to using Google DNS (8.8.8.8/8.8.4.4). This causes problems if you are forced to use internal DNS server. This can be fixed by executing: sudo sed 's@dns=dnsmasq@#dns=dnsmasq@' -i \ /etc/NetworkManager/NetworkManager.conf && \ sudo service network-manager restart If you have already installed Docker, you must restart the daemon for this change to take effect: sudo service docker restart The above commands turn off `dnsmasq` usage in NetworkManager configuration and restart network manager. They can be reversed by executing `sudo sed 's@#dns=dnsmasq@dns=dnsmasq@' -i /etc/NetworkManager/NetworkManager.conf && sudo service network-manager restart`. These instructions are adapted from [the Shipyard Project's QuickStart guide](https://github.com/shipyard/shipyard/wiki/QuickStart#127011-dns-server-problem-on-ubuntu). ### Cannot pull images from behind firewall that blocks TLS/SSL If you are behind a firewall that blocks TLS/SSL and pulling images from a private Docker registry, you must edit the system configuration so that the `--insecure-registry ` option is passed to the Docker daemon. For example, on Ubuntu: echo 'DOCKER_OPTS="--insecure-registry registry.example.com"' \ |sudo tee -a /etc/default/docker sudo service docker restart This does require the private registry to be available over plaintext HTTP. See [Docker daemon insecure registries documentation](https://docs.docker.com/reference/commandline/cli/#insecure-registries) for details. stack-3.7.1/doc/topics/editor_integration.md0000644000000000000000000000122014651506554017304 0ustar0000000000000000

# Haskell and C code ## Haskell packages with C code A Haskell package can include C source code. For example, consider a simple one-package Stack project named `c-example`, created by `stack new c-example` but with these changes: A C header file `my-library.h` added in new directory `include`: ~~~c #ifndef MY_LIBRARY_HEADER #define MY_LIBRARY_HEADER int max(int, int); #endif ~~~ A C source code file `my-library.c` added in new directory `c-source`: ~~~c #include "my-library.h" /* Function returning the larger of two integers */ int max(int x1, int x2) { if (x1 > x2) return x1; else return x2; } ~~~ A different Haskell module in source file `src/Lib.hs`, including a Haskell foreign import declaration making use of the C `max` function: ~~~haskell module Lib ( c_max ) where foreign import ccall "max" c_max :: Int -> Int -> Int ~~~ A different Haskell module in source file `app/Main.hs`, making use of the Haskell function `c_max` exported from module `Lib`: ~~~haskell module Main ( main ) where import Lib ( c_max ) main :: IO () main = print $ c_max 10 100 ~~~ The package's `package.yaml` file (simplied), used to create the package's Cabal file, might look like this: ~~~yaml spec-version: 0.36.0 name: c-example version: 0.1.0.0 extra-source-files: - include/my-library.h dependencies: - base >= 4.7 && < 5 library: source-dirs: src include-dirs: # Where to look for C header files? - include c-sources: # What C source code files to be compiled and linked? - c-source/my-library.c executables: c-example-exe: main: Main.hs source-dirs: app ghc-options: - -threaded - -rtsopts - -with-rtsopts=-N dependencies: - c-example ~~~ The project's `stack.yaml` file only needs to identify a snapshot: ~~~yaml snapshot: lts-23.24 # GHC 9.8.4 ~~~ This example project can be built with Stack in the normal way (`stack build`), and the built executable can then be executed in the Stack environment in the normal way (`stack exec c-example-exe`). ## Haskell packages with C `main` function A Haskell package can include an executable which has a `main` function written in C. For example, consider a simple one-package Stack project named `c-example`, with: A `package.yaml` describing a library and two executables, named `haskell-exe` and `c-exe`: ~~~yaml spec-version: 0.36.0 name: c-example version: 0.1.0.0 dependencies: base library: source-dirs: src # The Lib_stub.h header must be put by GHC somewhere where Cabal can find it. # This tells GHC to put it in the autogen-stubs directory of the project # directory. ghc-options: - -stubdir autogen-stubs executables: haskell-exe: main: Main.hs source-dirs: app ghc-options: - -threaded - -rtsopts - -with-rtsopts=-N dependencies: c-example c-exe: main: main.c source-dirs: c-app ghc-options: -no-hs-main # This specifies that directory autogen-stubs should be searched for header # files. include-dirs: autogen-stubs dependencies: c-example ~~~ !!! warning `Cabal-3.12.0.0`, a boot package of GHC 9.10.1, ignores `source-dirs` when the `main` file is not a Haskell source code file. This was a regression and fixed in subsequent versions of Cabal (the library). A Haskell module souce file named `Lib.hs` in directory `src`: ~~~haskell module Lib ( myMax -- Exported only for the use of the 'Haskell' executable ) where myMax :: Int -> Int -> Int myMax x1 x2 = if x1 > x2 then x1 else x2 foreign export ccall myMax :: Int -> Int -> Int ~~~ A Haskell module source file named `Main.hs` in directory `app`: ~~~haskell module Main ( main ) where import Lib ( myMax ) main :: IO () main = print $ myMax 10 100 ~~~ A C source file named `main.c` in directory `c-app`: ~~~c // Based in part on // https://downloads.haskell.org/ghc/latest/docs/users_guide/exts/ffi.html#using-your-own-main #include // Provides printf() #include // Provides hs_init() and hs_exit(). See the Haskell 2010 // Report, 8.7. // Parts specific to GHC #ifdef __GLASGOW_HASKELL__ #include "Lib_stub.h" // Automatically generated by GHC, given use of // foreign export ... in module Lib.hs ... #endif int main(int argc, char *argv[]) { // Initialises the Haskell system and provides it with the available command // line arguments hs_init(&argc, &argv); // Use our foreign export from module Lib.hs ... printf("%lld\n", myMax(10,100)); // De-initialise the Haskell system hs_exit(); return 0; } ~~~ The `foreign export` declaration in Haskell module `Lib` will cause GHC to generate a 'stub' C header file named `Lib_stub.h`. The GHC option `-stubdir` will cause GHC to put that file in the specified directory (`autogen-stubs`, in this example). !!! info If GHC's `-stubdir` option is omitted, GHC will put the generated C header file together with the other build artefacts for the module. However, that location cannot be specified reliably using the `include-dirs` key. That generated C header file will have content like: ~~~c #include #if defined(__cplusplus) extern "C" { #endif extern HsInt myMax(HsInt a1, HsInt a2); #if defined(__cplusplus) } #endif ~~~ The `include-dirs` key will cause the specified directory (again, `autogen-stubs` in this example) to be searched for C header files. The project's `stack.yaml` file only needs to identify a snapshot: ~~~yaml snapshot: lts-23.24 # GHC 9.8.4 ~~~ This example project can be built with Stack in the normal way (`stack build`), and the built executables can then be executed in the Stack environment in the normal way (`stack exec haskell-exe` for the 'Haskell' executable and `stack exec c-exe` for the 'C' executable). stack-3.7.1/doc/topics/index.md0000644000000000000000000000527714651506554014542 0ustar0000000000000000--- title: Topics ---

# Lock Files Stack attempts to provide reproducible build plans. This involves reproducibly getting the exact same contents of source packages and configuration options (like Cabal flags and GHC options) for a given set of input files. There are a few problems with making this work: * Entering all of the information to fully provide reproducibility is tedious. This would include things like Hackage revisions, hashes of remote tarballs, etc. Users don't want to enter this information. * Many operations in Stack rely upon a "snapshot hash," which transitively includes the completed information for all of these dependencies. If any of that information is missing when parsing the `stack.yaml` file or snapshot files, it could be expensive for Stack to calculate it. To address this, we follow the (fairly standard) approach of having a _lock file_. The goal of the lock file is to cache completed locations of project, snapshot packages and snapshots themselves so that: * These files can be stored in source control * Users on other machines can reuse these lock files and get identical build plans given that the used project packages and local snapshots are the same on those machines * Rerunning `stack build` in the future is deterministic in the build plan, not depending on mutable state in the world like Hackage revisions !!! note If, for example, a tarball available remotely is deleted or the hash changes, it will not be possible for Stack to perform the build. However, by deterministic, we mean it either performs the same build or fails, never accidentally doing something different. This document explains the contents of a lock file, how they are used, and how they are created and updated. ## stack.yaml and snapshot files Relevant to this discussion, Stack's project-level configuration file (`stack.yaml`, by default) specifies: * the parent snapshot (the [`snapshot`](../configure/yaml/project.md#snapshot) or [`resolver`](../configure/yaml/project.md#resolver) key) * extra-deps Some of this information can be incomplete. Consider this `stack.yaml` file: ~~~yaml snapshot: lts-19.22 packages: - . extra-deps: - acme-missiles-0.3 ~~~ This information is _incomplete_. For example, the extra-deps may change in the future. Instead, you could specify enough information in the `stack.yaml` file to fully resolve that package. That looks like: ~~~yaml extra-deps: - hackage: acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a687d45965778deb8694c5d1,613 pantry-tree: size: 226 sha256: 614bc0cca76937507ea0a5ccc17a504c997ce458d7f2f9e43b15a10c8eaeb033 ~~~ The `lts-19.22` information is also incomplete. While we assume in general that Haskell LTS snapshots never change, there's nothing that prohibits that from happening. Instead, the complete version of that key is: ~~~yaml snapshot: - url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/19/22.yaml size: 619399 sha256: 5098594e71bdefe0c13e9e6236f12e3414ef91a2b89b029fd30e8fc8087f3a07 ~~~ Users don't particularly feel like writing all of that. Therefore, it's common to see _incomplete_ information in a `stack.yaml` file. ## Recursive snapshot layers Snapshot files can be _recursive_, where `stack.yaml` refers to `foo.yaml`, which refers to `bar.yaml`, which refers to `baz.yaml`. A local snapshot file can refer to a remote snapshot file (available via an HTTP(S) URL). We need to encode information from _all_ of these snapshot layers and the `stack.yaml` file in the lock file, to ensure that we can detect if anything changes. ## Performance In addition to acting as a pure correctness mechanism, the design of a lock file given here also works as a performance improvement. Instead of requiring that all snapshot files be fully parsed on each Stack invocation, we can store information in the lock file and bypass parsing of the additional files in the common case of no changes. ## Lock file contents The lock file contains the following information: * Completed package locations for extra-deps and packages in snapshot files !!! note This only applies to _immutable_ packages. Mutable packages are not included in the lock file. * Completed information for the snapshot locations It looks like the following: ~~~yaml # Lock file, some message about the file being auto-generated snapshots: # Starts with the snapshot specified in stack.yaml, # then continues with the snapshot specified in each # subsequent snapshot file - original: foo.yaml # raw content specified in a snapshot file completed: file: foo.yaml sha256: XXXX size: XXXX - original: lts-13.9 completed: size: 496662 url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/13/9.yaml sha256: 83de9017d911cf7795f19353dba4d04bd24cd40622b7567ff61fc3f7223aa3ea packages: - original: https://hackage.haskell.org/package/acme-missiles-0.3.tar.gz completed: size: 1442 url: https://hackage.haskell.org/package/acme-missiles-0.3.tar.gz name: acme-missiles version: '0.3' sha256: e563d8b524017a06b32768c4db8eff1f822f3fb22a90320b7e414402647b735b pantry-tree: size: 226 sha256: 614bc0cca76937507ea0a5ccc17a504c997ce458d7f2f9e43b15a10c8eaeb033 ~~~ ## Creation procedure Whenever a project-level configuration file (`stack.yaml`, by default) is loaded, Stack checks for a lock file in the same file path, with a `.lock` extension added. For example, if you command: ~~~text stack --stack-yaml my-stack.yaml build ~~~ or ~~~text stack --stack-yaml my-stack.yaml build --dry-run ~~~ then Stack will use a lock file in the location `my-stack.yaml.lock`. For the rest of this document, we'll assume that the files are simply `stack.yaml` and `stack.yaml.lock`. If the lock file does not exist, subject to Stack's [`--lock-file`](../configure/global_flags.md#-lock-file-option) option, it will be created by: * Loading the `stack.yaml` * Loading all snapshot files * Completing all missing information * Writing out the new `stack.yaml.lock` file to the disk ## Update procedure Whenever a project-level configuration file (`stack.yaml`, by default) is loaded, all completed package or snapshot locations (even those completed using information from a lock file) get collected to form a new lock file in memory. Subject to Stack's [`--lock-file`](../configure/global_flags.md#-lock-file-option) option, that new lock file is compared against the one on disk and, if there are any differences, written out to the disk. ## `stack config build-files` command The [`stack config build-files`](../commands/config_command.md#the-stack-config-build-files-command) loads a project-level configuration file (see above) without taking any other build steps (other than generating, when applicable, a Cabal file from a package description in the Hpack format). stack-3.7.1/doc/topics/nix_integration.md0000644000000000000000000004511614765330073016625 0ustar0000000000000000
# Nix integration [:octicons-tag-24: 0.1.10.0](https://github.com/commercialhaskell/stack/releases/tag/v0.1.10.0) [Nix](https://nixos.org/) is a purely functional package manager. Stack can be configured to integrate with Nix. Integration provides these benefits: * more reproducible builds. This is because fixed versions of any system libraries and commands required to build the project are automatically built using Nix and managed locally for each project. These system packages never conflict with any existing versions of these libraries on your system. That they are managed locally to the project means that you don't need to alter your system in any way to build any odd project pulled from the Internet; and * implicit sharing of system packages between projects. This means you don't have more copies on-disk than you need. The Nix package manager is a pre-requisite for integration. On Linux (including Windows Subsystem for Linux) and macOS, it can be downloaded and installed from the [Nix download page](https://nixos.org/download.html). When integrated with Nix, Stack handles Haskell dependencies as it usually does and the Nix package manager handles the _non-Haskell_ dependencies needed by the Haskell packages. Stack downloads Haskell packages from [Stackage](https://www.stackage.org/lts) and builds them locally. Stack uses Nix to download [Nix packages][nix-search-packages]. These provide the GHC compiler and external C libraries that you would normally install manually. Nix's `nix-shell` starts an interactive shell based on a Nix expression. Stack can automatically create a Nix build environment in the background using `nix-shell`. There are two alternative options to create such a build environment: 1. provide a list of [Nix packages][nix-search-packages] 2. provide a `shell.nix` file that gives you more control over the libraries and tools available inside the shell. A `shell.nix` file requires writing code in Nix's [custom language][nix-language]. Use this option only if you know Nix and have special requirements, such as using custom Nix packages that override the standard ones or using system libraries with special requirements. ## Checking the Nix installation Once Nix is installed, the Nix commands (`nix-shell` etc) should be available. If they are not, it could be because the file `$HOME/.nix-profile/etc/profile.d/nix.sh` is not sourced by your shell. You should either: 1. run `source ~/.nix-profile/etc/profile.d/nix.sh` each time you open a terminal and need Nix; or 2. add the command `source ~/.nix-profile/etc/profile.d/nix.sh` to your `~/.bashrc` or `~/.bash_profile` file. A Nix path can be specified between angle brackets, e.g. ``, and the directories listed in the `NIX_PATH` environment variable will be searched for the given file or directory name. Stack makes use of path ``. From Nix 2.4, `NIX_PATH` is not set by `nix.sh`. If `NIX_PATH` is not set, Nix will fall back to (first) `$HOME/.nix-defexpr/channels` in impure and unrestricted evaluation mode. However, Stack may use a pure Nix mode (see further [below](#pure-and-impure-nix-shells)). That directory can be appended to `NIX_PATH` with `export NIX_PATH=${NIX_PATH:+$NIX_PATH:}$HOME/.nix-defexpr/channels`. For information about how Stack itself can configure `NIX_PATH`, see further [below](#nix-package-sources). ## Enable Nix integration On NixOS, Nix integration is enabled by default; on other operating systems it is disabled. To enable Nix integration, add the following section to your Stack configuration file (`stack.yaml` or `config.yaml`): ~~~yaml nix: enable: true # false by default, except on NixOS ~~~ The equivalent command line flag (which will prevail) is `--[no-]nix`. Passing any `--nix-*` option on the command line will imply the `--nix` option. If Nix integration is not enabled, Stack will notify the user if a `nix` executable is on the PATH. If that notification is unwanted, it can be muted by setting Stack's configuration option [`notify-if-nix-on-path`](../configure/yaml/non-project.md#notify-if-nix-on-path) to `false`. With Nix integration enabled, `stack build` and `stack exec` will automatically launch themselves in a local build environment (using `nix-shell` behind the scenes). It is not necessary to run `stack setup`, unless you want to cache a GHC installation before running a build. **Known limitation on macOS:** currently, `stack --nix ghci` fails on macOS, due to a bug in GHCi when working with external shared libraries. ## Supporting both Nix and non-Nix developers With Nix integration enabled in Stack's configuration file, every developer of your project needs to have Nix installed, but the developer also gets all external libraries automatically. Julien Debon of Tweag has published a [blog post][tweag-blog-post] on *Smooth, non-invasive Haskell Stack and Nix shell integration* (2 June 2022). The post explains how to set things up so that both Nix and non-Nix developers can work together on the same project. The `tweag/haskell-stack-nix-example` [GitHub repository][tweag-example] provides an example of working Stack and Nix shell integration to accompany the post. Nix 2.4 (released 1 November 2021) introduced a new and experimental format to package Nix-based projects, known as 'flakes'. The example below adapts and extends the example accompanying the blog post above to use Nix flakes. The `flake.nix` file is: ~~~nix { description = "my project description"; inputs.nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable"; inputs.flake-utils.url = "github:numtide/flake-utils"; outputs = { self, nixpkgs, flake-utils }: flake-utils.lib.eachDefaultSystem (system: let pkgs = nixpkgs.legacyPackages.${system}; hPkgs = pkgs.haskell.packages."ghc8107"; # need to match Stackage LTS version # from stack.yaml snapshot myDevTools = [ hPkgs.ghc # GHC compiler in the desired version (will be available on PATH) hPkgs.ghcid # Continuous terminal Haskell compile checker hPkgs.ormolu # Haskell formatter hPkgs.hlint # Haskell codestyle checker hPkgs.hoogle # Lookup Haskell documentation hPkgs.haskell-language-server # LSP server for editor hPkgs.implicit-hie # auto generate LSP hie.yaml file from cabal hPkgs.retrie # Haskell refactoring tool # hPkgs.cabal-install stack-wrapped pkgs.zlib # External C library needed by some Haskell packages ]; # Wrap Stack to work with our Nix integration. We don't want to modify # stack.yaml so non-Nix users don't notice anything. # - no-nix: We don't want Stack's way of integrating Nix. # --system-ghc # Use the existing GHC on PATH (will come from this Nix file) # --no-install-ghc # Don't try to install GHC if no matching GHC found on PATH stack-wrapped = pkgs.symlinkJoin { name = "stack"; # will be available as the usual `stack` in terminal paths = [ pkgs.stack ]; buildInputs = [ pkgs.makeWrapper ]; postBuild = '' wrapProgram $out/bin/stack \ --add-flags "\ --no-nix \ --system-ghc \ --no-install-ghc \ " ''; }; in { devShells.default = pkgs.mkShell { buildInputs = myDevTools; # Make external Nix c libraries like zlib known to GHC, like # pkgs.haskell.lib.buildStackProject does # https://github.com/NixOS/nixpkgs/blob/d64780ea0e22b5f61cd6012a456869c702a72f20/pkgs/development/haskell-modules/generic-stack-builder.nix#L38 LD_LIBRARY_PATH = pkgs.lib.makeLibraryPath myDevTools; }; }); } ~~~ Check-in this `flake.nix` to your project's repository. Run the `nix develop` command (it searches for `flake.nix` by default) and you'll find a new `flake.lock` file. That file that pins the precise nixpkgs package set. Check-in that `flake.lock` file as well, and every Nix developer of your project will use precisely the same package set. ## GHC through Nix packages Nix integration will instruct Stack to build inside a local build environment. That environment will also download and use a [GHC Nix package](https://search.nixos.org/packages?query=haskell.compiler.ghc) matching the required version of the configured Stack [snapshot](../configure/yaml/project.md#snapshot). Enabling Nix integration means that packages will always be built using the local GHC from Nix inside your shell, rather than your globally installed system GHC (if any). Stack can use only GHC versions that are in the Nix package repository. The [Nixpkgs master branch](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/haskell-modules) usually picks up new versions quickly, but it takes two or three days before those updates arrive in the `unstable` channel. Release channels, like `nixos-22.05`, receive those updates only occasionally -- say, every two or three months --, so you should not expect them to have the latest compiler available. Fresh NixOS installs use a release version by default. To identify whether a given compiler is available, you can use the following Nix command: ~~~sh nix-env -f "" -qaP -A haskell.compiler.ghc924 haskell.compiler.ghc924 ghc-9.2.4 ~~~ If Nix doesn't know that version of GHC, you'll see the following error message: ~~~sh nix-env -f "" -qaP -A haskell.compiler.ghc999 error: attribute ‘ghc999’ in selection path ‘haskell.compiler.ghc999’ not found ~~~ You can list all known Haskell compilers in Nix with the following: ~~~sh nix-instantiate --eval -E "with import {}; lib.attrNames haskell.compiler" ~~~ Alternatively, use `nix repl`, a convenient tool to explore nixpkgs: ~~~sh nix repl ~~~ In the REPL, load nixpkgs and get the same information through autocomplete: ~~~sh nix-repl> :l nix-repl> haskell.compiler.ghc ~~~ You can type and evaluate any Nix expression in the Nix REPL, such as the one we gave to `nix-instantiate` earlier. ## External C libraries through Nix packages To let Nix manage external C libraries, add (for example) the following section to your Stack configuration file: ~~~yaml nix: enable: true packages: [zlib, glpk, pcre] ~~~ The equivalent command line option is `--nix-packages "zlib glpk pcre"`. The `packages` key and the `shell-file` key (see further below) are alternatives. Specifying both results in an error. The example above will instruct Stack to build inside a local build environment that will have the Nix packages [zlib](https://search.nixos.org/packages?query=zlib), [glpk](https://search.nixos.org/packages?query=glpk) and [pcre](https://search.nixos.org/packages?query=pcre) installed, which provide the C libraries of the same names. **Note:** currently, Stack only discovers dynamic and static libraries in the `lib/` folder of any Nix package, and likewise header files in the `include/` folder. If you're dealing with a package that doesn't follow this standard layout, you'll have to deal with that using a custom `shell.nix` file (see further below). ## External C libraries through a `shell.nix` file In Nix, a 'derivation' is a description of a build action and its result is a Nix store object. Nix's [custom language][nix-language] can provide a fully customized derivation as an environment to use. To specify such a `shell.nix` file, add the following section to your Stack configuration file: ~~~yaml nix: enable: true shell-file: shell.nix ~~~ The equivalent command line option (which will prevail) is `--nix-shell-file shell.nix`. The `packages` and `shell-file` keys are alternatives. Specifying both results in an error. Defining a `shell.nix` file allow you to override some Nix derivations, for instance to change some build options of the libraries you use, or to set additional environment variables. For further information, see the [Nix manual][nix-manual-exprs]. The `shell.nix` file that is the equivalent of the `packages: [zlib, glpk, pcre]` example above is: ~~~nix {ghc}: with (import {}); haskell.lib.buildStackProject { inherit ghc; name = "myEnv"; buildInputs = [ zlib glpk pcre ]; } ~~~ The `buildStackProject` utility function is documented in the [Nixpkgs manual][nixpkgs-manual-haskell]. Stack expects the `shell.nix` file to define a function of with one argument called `ghc` (arguments are not positional), which you should give to function `buildStackProject`. This argument is a GHC Nix package in the version as defined in the snapshot you set in Stack's project-level configuration file (`stack.yaml`, by default). ## Pure and impure Nix shells By default, Stack will run the build in a *pure* Nix build environment (or *shell*). Building in a pure Nix shell means: 1. with limited exceptions, **no environment variable will be forwarded** from your user session to the Nix shell (variables like `HTTP_PROXY`, `PATH`, `STACK_XDG` and `STACK_ROOT` notably will not be available); and 2. the build should fail if you have not specified all the dependencies in the `packages:` section of the Stack configuration file, even if these dependencies are installed elsewhere on your system. This behaviour enforces a complete description of the build environment to facilitate reproducibility. To override this behaviour, add the following section to your Stack YAML configuration file: ~~~yaml nix: enable: true pure: false ~~~ The equivalent command line flag (which will prevail) is `--[no-]-nix-pure`. To run the build in a *pure* Nix shell but preserve specific environment variables use Nix's `nix-shell` command's `--keep` option. For example, to preserve the [`STACK_XDG`](../configure/environment_variables.md#stack_xdg) environment variable, add the following to your Stack YAML configuration file: ~~~yaml nix: nix-shell-options: - --keep - STACK_XDG ~~~ The equivalent command line option is: ~~~text --nix-shell-options "--keep STACK_XDG" ~~~ **Note:** On macOS, shells are non-pure by default currently. This is due soon to be resolved locale issues. So on macOS you'll need to be a bit more careful to check that you really have listed all dependencies. ## Nix package sources Nix organizes its packages in snapshots of packages (each snapshot being a "package set") similar to how Stackage organizes Haskell packages. By default, `nix-shell` will look for the "nixpkgs" package set located by your `NIX_PATH` environment variable. This package set can be different depending on when you installed Nix and which nixpkgs channel you're using (similar to the LTS channel for stable packages and the nightly channel for bleeding edge packages in [Stackage](https://www.stackage.org/)). This is bad for reproducibility so that nixpkgs should be pinned, i.e., set to the same package set for every developer of your project. To set or override the Nix package set, add the following section to your Stack configuration file: ~~~yaml nix: path: [nixpkgs=] ~~~ The equivalent command line option is `--nix-path `. By this means, you can ask Nix to use your own local checkout of the nixpkgs repository. You could in this way use a bleeding edge nixpkgs, cloned from the `NixOS/nixpkgs` [repository](http://www.github.com/NixOS/nixpkgs) `master` branch, or edit the Nix descriptions of some packages. The Tweag example [repository][tweag-example] shows how you can pin a package set. ## Non-project specific configuration Below is a summary of the non-project specific configuration options and their default values. The options can be set in Stack's project-level configuration file (`stack.yaml`, by default) or its global configuration file (`config.yaml`). ~~~yaml nix: # false by default, except on NixOS. Is Nix integration enabled? enable: true # true by default. Should Nix run in a pure shell? pure: true # Empty by default. The list of packages you want to be available in the # nix-shell at build time (with `stack build`) and run time (with # `stack exec`). packages: [] # Unset by default. You cannot set this option if `packages:` # is already present and not empty. shell-file: shell.nix # A list of strings, empty by default. Additional options that will be passed # verbatim to the `nix-shell` command. nix-shell-options: [] # A list of strings, empty by default, such as # `[nixpkgs=/my/local/nixpkgs/clone]` that will be used to override # NIX_PATH. path: [] # false by default. Whether to add your Nix dependencies as Nix garbage # collection roots. This way, calling nix-collect-garbage will not remove # those packages from the Nix store, saving you some time when running # stack build again with Nix support activated. # # This creates a `nix-gc-symlinks` directory in the project `.stack-work`. # To revert that, just delete this `nix-gc-symlinks` directory. add-gc-roots: false ~~~ `stack --nix-help` will list the equivalent command line flags and options. ## Stack and developer tools on NixOS NixOS is a Linux distribution based on Nix, that is composed using modules and packages defined in the Nixpkgs project. When using Stack on NixOS, you must use Stack's Nix integration to install GHC. That is because external C libraries in NixOS are not installed in the usual distribution directories. GHC installed through Stack (without Nix) can't find those libraries and, therefore, can't build most projects. However, GHC provided through Nix can be modified to find the external C libraries provided through Nix.

# Non-standard project initialization You may need to configure Stack to work with an existing project that has one or more Cabal files but no Stack project-level configuration file (`stack.yaml`, by default). ## The `stack init` command The `stack init` command: * finds all of the Cabal files in your current directory and subdirectories (unless you use `--ignore-subdirs`) and determines the packages and versions they require * Finds the best combination of snapshot and package flags that allows everything to compile with minimum external dependencies * Tries to look for the best matching snapshot from latest Haskell LTS, latest Stackage Nightly, and other Haskell LTS, in that order If `stack init` finds a match, it will generate a `stack.yaml` file. You can specify the directory, or directories to include in the search for Cabal files. ### The `stack init --force` flag Set the flag to force the over-writing of any existing `stack.yaml` file. ### The `stack init --ignore-subdirs` flag Set the flag to not search for Cabal files in subdirectories. ### The `stack init --omit-packages` flag Set the flag to exclude any conflicting or incompatible user packages. stack-3.7.1/doc/topics/package_location.md0000644000000000000000000002035515023557525016706 0ustar0000000000000000
# Package location [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) This document describes the specification of a package location (in the `extra-deps` key and in a snapshot). !!! info Stack uses the [Pantry](https://hackage.haskell.org/package/pantry) to specify the location of packages. Pantry is geared towards reproducible build plans with cryptographically secure specification of packages. There are three types of package locations: 1. Hackage packages 2. Git and Mecurial repositories 3. Local or remote archives (such as GitHub archives) All three types support optional tree metadata to be added, which can be used for reproducibility and faster downloads. This information can automatically be generated in a [lock file](lock_files.md). ## Hackage packages A package can be identified by its name, version and Cabal file revision number, with revision `0` being the original Cabal file. For example: ~~~yaml extra-deps: - acme-missiles-0.3@rev:0 ~~~ A package name and version only can be stated. Using this syntax, the most recent Cabal file revision available in the package index will be used. For example: ~~~yaml extra-deps: - acme-missiles-0.3 ~~~ This syntax is often used in practice, but may result in one build differing from another, if a new or further Cabal file revision is added to the package index between the builds. As an alternative to specifying the Cabal file revision number, you can specify the package name and version with the SHA256 hash of the contents of its Cabal file. Doing so is slightly more resilient than using the Cabal file revision number, as it does not rely on the correct ordering in the package index. For example: ~~~yaml extra-deps: - acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a687d45965778deb8694c5d1 ~~~ Optionally, you can specify also the size of the Cabal file in bytes. For example (where the file size is `631` bytes): ~~~yaml extra-deps: - acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a687d45965778deb8694c5d1,613 ~~~ Optionally, you can specify also the Pantry tree information. For example: ~~~yaml - hackage: acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a687d45965778deb8694c5d1,613 pantry-tree: size: 226 sha256: 614bc0cca76937507ea0a5ccc17a504c997ce458d7f2f9e43b15a10c8eaeb033 ~~~ A Pantry tree is a list of CAS (content-addressable storage) 'SHA256 hash'-'size in bytes' keys for each of the files in a package. The SHA256 hash of the contents of the Cabal file and its size in bytes is provided in Stack's lock file. For further information, see the [lock files](lock_files.md) documentation. The SHA256 hash and file size alternative is also what Stack uses when it makes suggestions about missing packages. ## Git and Mercurial repositories You can specify a Git or Mercurial repository at a specific commit, and Stack will clone that repository and, if it has submodules (Git), update the repository's submodules. For example: ~~~yaml extra-deps: - git: git@github.com:commercialhaskell/stack.git commit: '6a86ee32e5b869a877151f74064572225e1a0398' - git: git@github.com:snoyberg/http-client.git commit: 'a5f4f3' - hg: https://example.com/hg/repo commit: 'da39a3ee5e6b4b0d3255bfef95601890afd80709' ~~~ !!! note It is highly recommended that you only use SHA1 values for a Git or Mercurial commit. Other values may work, but they are not officially supported, and may result in unexpected behavior (namely, Stack will not automatically pull to update to new versions). Another problem with this is that your build will not be deterministic, because when someone else tries to build the project they can get a different checkout of the package. !!! note The `commit:` key expects a YAML string. A commit hash, or partial hash, comprised only of digits represents a YAML number, unless it is enclosed in quotation marks. !!! warning For the contents of a Git repository, Stack cannot handle filepaths or symbolic link names that are longer than those supported by the `ustar` (Unix Standard TAR) archive format defined by [POSIX.1-1988](https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub151-1.pdf). Stack uses `git archive` to convert the content of a Git repository to a TAR archive, which it then seeks to consume. Git produces `pax` format archives which use 'extended' headers for matters that the `ustar` format cannot handle. Unfortunately, Stack cannot consume an extended header and will silently discard the item. A common practice in the Haskell world is to use "megarepos", or repositories with multiple packages in various subdirectories. Some common examples include [wai](https://github.com/yesodweb/wai/) and [digestive-functors](https://github.com/jaspervdj/digestive-functors). To support this, you may also specify `subdirs` for repositories. For example: ~~~yaml extra-deps: - git: git@github.com:yesodweb/wai commit: '2f8a8e1b771829f4a8a77c0111352ce45a14c30f' subdirs: - auto-update - wai ~~~ If unspecified, `subdirs` defaults to `['.']` meaning looking for a package in the root of the repository. If you specify a value of `subdirs`, then `'.'` is _not_ included by default and needs to be explicitly specified if a required package is found in the top-level directory of the repository. ### git-annex [git-annex](https://git-annex.branchable.com) is not supported. This is because `git archive` does not handle symbolic links outside the work tree. It is still possible to use repositories which use git-annex but do not require the annex files for the package to be built. To do so, ensure that any files or directories stored by git-annex are marked [export-ignore](https://git-scm.com/docs/git-archive#Documentation/git-archive.txt-export-ignore) in the `.gitattributes` file in the repository. For further information, see issue [#4579](https://github.com/commercialhaskell/stack/issues/4579). For example, if the directory `fonts/` is controlled by git-annex, use the following line: ~~~gitattributes fonts export-ignore ~~~ ## Local or remote archives (such as GitHub archives) ### Filepaths or URLs to archive files You can use filepaths referring to local archive files or HTTP or HTTPS URLs referring to remote archive files, either tarballs or ZIP files. !!! note An example of a remote archive file is a Hackage package candidate, usually located at (for example) https://hackage.haskell.org/package/my-package-1.0.0/candidate/my-package-1.0.0.tar.gz. !!! warning Stack assumes that these archive files never change after downloading to avoid needing to make an HTTP request on each build. For safer, more reproducible builds, you can optionally specify a cryptographic hash of the archive file. For example: ~~~yaml extra-deps: - https://example.com/foo/bar/baz-0.0.2.tar.gz - archive: http://github.com/yesodweb/wai/archive/2f8a8e1b771829f4a8a77c0111352ce45a14c30f.zip subdirs: - wai - warp - archive: ../acme-missiles-0.3.tar.gz sha256: e563d8b524017a06b32768c4db8eff1f822f3fb22a90320b7e414402647b735b ~~~ ### GitHub archive files [:octicons-tag-24: 1.7.1](https://github.com/commercialhaskell/stack/releases/tag/v1.7.1) You can specify a GitHub respository at a specific commit and Stack will obtain from GitHub an archive file of the files in the repository at that point in its history. For example: ~~~yaml extra-deps: - github: snoyberg/http-client commit: 'a5f4f30f01366738f913968163d856366d7e0342' ~~~ !!! note An archive file of the files in a GitHub repository at a point in its history is not the same as a clone of the repository (including its history) and the updating of any submodules. If you need the latter, use the syntax for a [Git repository](#git-and-mercurial-repositories). If the package fails to build due to missing files, it may be that updated submodules are required. stack-3.7.1/doc/topics/scripts.md0000644000000000000000000002611715023557531015111 0ustar0000000000000000
# Stack's script interpreter Stack offers a very useful feature for running files: a script interpreter. For too long have Haskellers felt shackled to bash or Python because it's just too hard to create reusable source-only Haskell scripts. Stack attempts to solve that. You can use `stack ` to execute a Haskell source file. Usually, the Stack command to be applied is specified using a special Haskell comment (the Stack interpreter options comment) at the start of the source file. That command is most often [`stack script`](../commands/script_command.md) but it can be, for example, [`stack runghc`](../commands/runghc_command.md). If there is no Stack interpreter options comment, Stack will warn that one was expected. An example will be easiest to understand. Consider the Haskell source file `turtle-example.hs` with contents: ~~~haskell #!/usr/bin/env stack -- stack script --snapshot lts-23.24 --package turtle {-# LANGUAGE OverloadedStrings #-} import Turtle (echo) main = echo "Hello World!" ~~~ === "Unix-like" The first line beginning with the 'shebang' (`#!`) tells Unix to use Stack as a script interpreter, if the file's permissions mark it as executable. A shebang line is limited to a single argument, here `stack`. The file's permissions can be set with command `chmod` and then it can be run: ~~~text chmod +x turtle-example.hs ./turtle-example.hs ~~~ !!! note On macOS: - Avoid `{-# LANGUAGE CPP #-}` in Stack scripts; it breaks the shebang line ([GHC #6132](https://gitlab.haskell.org/ghc/ghc/issues/6132)) - Use a compiled executable, not another script, in the shebang line. Eg `#!/usr/bin/env runhaskell` will work but `#!/usr/local/bin/runhaskell` would not. Alternatively, the script can be run with command: ~~~text stack turtle-example.hs ~~~ === "Windows" The first line beginning with the 'shebang' (`#!`) has a meaning on Unix-like operating systems but will be ignored by PowerShell. It can be omitted on Windows. The script can be run with command: ~~~text stack turtle-example.hs ~~~ In both cases, the command yields: ~~~text Hello World! ~~~ the first time after a little delay (as GHC is downloaded, if necessary, and dependencies are built) and subsequent times more promptly (as the runs are able to reuse everything already built). The second line of the source code is the Stack interpreter options comment. In this example, it specifies the [`stack script`](../commands/script_command.md) command with the options of a LTS Haskell 23.24 snapshot (`--snapshot lts-23.24`) and ensuring the [`turtle`](https://hackage.haskell.org/package/turtle) package is available (`--package turtle`). The version of the package will be that in the specified snapshot (`lts-23.24` provides `turtle-1.6.2`). ## Arguments and interpreter options and arguments Arguments for the script can be specified on the command line after the file name: `stack ...`. The Stack interpreter options comment must specify what would be a single valid Stack command at the command line if the file name were included as an argument, starting with `stack`. It can include `--` followed by arguments. In particular, the Stack command `stack MyScript.hs ` with Stack interpreter options comment: ~~~haskell -- stack -- ~~~ is equivalent to the following command at the command line: ~~~text stack -- MyScript.hs ~~~ The Stack interpreter options comment must be the first line of the file, unless a shebang line is the first line, when the comment must be the second line. The comment must start in the first column of the line. When many options are needed, a block style comment that splits the command over more than one line may be more convenient and easier to read. For example, the command `stack MyScript.hs arg1 arg2` with `MyScript.hs`: ~~~haskell #!/usr/bin/env stack {- stack script --snapshot lts-23.24 -- +RTS -s -RTS -} import Data.List (intercalate) import System.Environment (getArgs) import Turtle (echo, fromString) main = do args <- getArgs echo $ fromString $ intercalate ", " args ~~~ is equivalent to the following command at the command line: ~~~text stack script --snapshot lts-23.24 -- MyScript.hs arg1 arg2 +RTS -s -RTS ~~~ where `+RTS -s -RTS` are some of GHC's [runtime system (RTS) options](https://downloads.haskell.org/~ghc/latest/docs/users_guide/runtime_control.html). Arguments that include spaces can be quoted using double quotation marks. ## Just-in-time compilation As with using [`stack script`](../commands/script_command.md) at the command line, you can pass the `--compile` flag to make Stack compile the script, and then run the compiled executable. Compilation is done quickly, without optimization. To compile with optimization, pass the `--optimize` flag instead. Compilation is done only if needed; if the executable already exists, and is newer than the script, Stack just runs the executable directly. This feature can be good for speed (your script runs faster) and also for durability (the executable remains runnable even if the script is disturbed, eg due to changes in your installed GHC/snapshots, changes to source files during git bisect, etc.) ## Using multiple packages As with using [`stack script`](../commands/script_command.md) at the command line, you can also specify multiple packages, either with multiple `--package` options, or by providing a comma or space separated list. For example: ~~~haskell #!/usr/bin/env stack {- stack script --snapshot lts-23.24 --package turtle --package "stm async" --package http-client,http-conduit -} ~~~ ## Using extra-deps As with using [`stack script`](../commands/script_command.md) at the command line, you can also specify one or more extra-deps using a valid YAML value for each. For example: ~~~haskell #!/usr/bin/env stack {- stack script --snapshot lts-23.24 --extra-dep acme-missiles-0.3@rev:0 --extra-dep "{git: git@github.com:yesodweb/wai, commit: '2f8a8e1b771829f4a8a77c0111352ce45a14c30f', subdirs: [auto-update, wai]}" -} ~~~ Relative paths to local archive files are assumed to be relative to the directory in which the script file is located. ## Stack configuration for scripts When using the [`stack script`](../commands/script_command.md) command, as when using it at the command line, any project-level configuration file (`stack.yaml`, by default) (including in the `global-project` directory in the Stack root), including any specified by the options to the `stack script` command itself, is ignored. !!! info Non-project level configuration options in global configuration files (`config.yaml`), are not ignored by the [`stack script`](../commands/script_command.md) command. Such options may be useful if [`allow-newer`](../configure/yaml/non-project.md#allow-newer) and/or [`allow-newer-deps`](../configure/yaml/non-project.md#allow-newer-deps) are required. When using the [`stack runghc`](../commands/runghc_command.md) command, as when using it at the command line, if the current working directory is inside a project, then that project's project-level configuration file is effective when running the script. Otherwise the script uses the project-level configuration file in the `global-project` directory in the Stack root. ## Testing scripts You can use the flag `--script-no-run-compile` on the command line to enable (it is disabled by default) the use of the `--no-run` option with [`stack script`](../commands/script_command.md) (and forcing the `--compile` option). The flag may help test that scripts compile in CI (continuous integration). For example, consider the following simple script, in a file named `Script.hs`, which makes use of the joke package [`acme-missiles`](https://hackage.haskell.org/package/acme-missiles): ~~~haskell {- stack script --snapshot lts-23.24 --package acme-missiles -} import Acme.Missiles (launchMissiles) main :: IO () main = launchMissiles ~~~ The command `stack --script-no-run-compile Script.hs` then behaves as if the command `stack script --snapshot lts-23.24 --package acme-missiles --no-run --compile -- Script.hs` had been given. `Script.hs` is compiled (without optimisation) and the resulting executable is not run: no missiles are launched in the process! ## Writing independent and reliable scripts The [`stack script`](../commands/script_command.md) command will automatically: * Install GHC and libraries, if missing. [`stack script`](../commands/script_command.md) behaves as if the `--install-ghc` flag had been passed at the command line. * Require that all packages used be explicitly stated on the command line. This ensures that your scripts are _independent_ of any prior deployment specific configuration, and are _reliable_ by using exactly the same version of all packages every time it runs so that the script does not break by accidentally using incompatible package versions. In earlier versions of Stack, the [`stack runghc`](../commands/runghc_command.md) command was used for scripts and can still be used in that way. In order to achieve the same effect with the [`stack runghc`](../commands/runghc_command.md) command, you can do the following: 1. Use the `--install-ghc` option to install the compiler automatically 2. Explicitly specify all packages required by the script using the `--package` option. Use `-hide-all-packages` GHC option to force explicit specification of all packages. 3. Use the `--snapshot` Stack option to ensure a specific GHC version and package set is used. It is possible for a project-level configuration file to affect [`stack runghc`](../commands/runghc_command.md). For that reason, [`stack script`](../commands/script_command.md) is strongly recommended. For those curious, here is an example with [`stack runghc`](../commands/runghc_command.md): ~~~haskell #!/usr/bin/env stack {- stack runghc --install-ghc --snapshot lts-23.24 --package base --package turtle -- -hide-all-packages -} ~~~ The [`stack runghc`](../commands/runghc_command.md) command is still useful, especially when you're working on a project and want to access the package databases and configurations used by that project. See the next section for more information on configuration files. ## Loading scripts in GHCi Sometimes you want to load your script in GHCi to play around with your program. In those cases, you can use `exec ghci` option in the script to achieve it. Here is an example: ~~~haskell #!/usr/bin/env stack {- stack exec ghci --install-ghc --snapshot lts-23.24 --package turtle -} ~~~ stack-3.7.1/doc/topics/shell_autocompletion.md0000644000000000000000000000403214651506554017650 0ustar0000000000000000
# Shell auto-completion The following adds support for the tab completion of standard Stack arguments to the following shell programs: Bash, Zsh (the Z shell) and fish. Completion of file names and executables within Stack is still lacking. For further information, see issue [#823](https://github.com/commercialhaskell/stack/issues/832). !!! info Stack's completion library provides [hidden options](https://github.com/pcapriotti/optparse-applicative#bash-zsh-and-fish-completions) for Bash, Zsh, and fish which output commands used for shell auto-completion. For example: ~~~bash $ stack --bash-completion-script stack _stack() { local CMDLINE local IFS=$'\n' CMDLINE=(--bash-completion-index $COMP_CWORD) for arg in ${COMP_WORDS[@]}; do CMDLINE=(${CMDLINE[@]} --bash-completion-word $arg) done COMPREPLY=( $(stack "${CMDLINE[@]}") ) } complete -o filenames -F _stack stack ~~~ === "Bash" Add the output of the following command to your preferred completions file (e.g. `~/.config/bash_completions.d/stack`). ~~~bash stack --bash-completion-script $(which stack) ~~~ You may need to `source` this. === "Zsh" Add the output of the following command to your preferred completions file (e.g. `~/.config/zsh/completions/_stack`). ~~~zsh stack --zsh-completion-script $(which stack) ~~~ You won't need to `source` this, but do update your `fpath`: ~~~zsh fpath=($HOME/.config/zsh/completions $fpath) autoload -U compinit && compinit ~~~ === "fish" Add the output of the following command to your preferred completions file (e.g. `~/.config/fish/completions/stack.fish`). ~~~fish stack --fish-completion-script $(which stack) ~~~ stack-3.7.1/doc/topics/snapshot_location.md0000644000000000000000000000620714765330073017151 0ustar0000000000000000
# Snapshot location [:octicons-tag-24: 2.1.1](https://github.com/commercialhaskell/stack/releases/tag/v2.1.1) This document describes the specification of a snapshot location (in the [`snapshot`](../configure/yaml/project.md#snapshot) or [`resolver`](../configure/yaml/project.md#resolver) key). !!! info Stack uses the [Pantry](https://hackage.haskell.org/package/pantry) to specify the location of snapshots. Pantry is geared towards reproducible build plans with cryptographically secure specification of snapshots. There are essentially four different ways of specifying a snapshot location: 1. Via a compiler version, which is a "compiler only" snapshot. This could be, for example: ~~~yaml snapshot: ghc-8.6.5 ~~~ 2. Via a URL pointing to a snapshot configuration file, for example: ~~~yaml snapshot: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/nightly/2018/8/21.yaml` ~~~ 3. Via a local file path pointing to a snapshot configuration file, for example: ~~~yaml snapshot: my-local-snapshot.yaml ~~~ 4. Via a _convenience synonym_, which provides a short form for some common URLs. These are: * GitHub: `github:user/repo:path` is treated as: ~~~text https://raw.githubusercontent.com/user/repo/master/path ~~~ * LTS Haskell: `lts-X.Y` is treated (by default) as: ~~~text github:commercialhaskell/stackage-snapshots:lts/X/Y.yaml ~~~ and, consequently, expands to: ~~~text https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/X/Y.yaml ~~~ * Stackage Nightly: `nightly-YYYY-MM-DD` is treated (by default) as: ~~~text github:commercialhaskell/stackage-snapshots:nightly/YYYY/M/D.yaml ~~~ and, consequently, expands to: ~~~text https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/nightly/YYYY/M/D.yaml ~~~ !!! info "Overriding the default snapshot location base" By default, LTS Haskell and Stackage Nightly snapshot configurations are retrieved from the `stackage-snapshots` GitHub repository of user `commercialhaskell`. The [snapshot-location-base](../configure/yaml/non-project.md#snapshot-location-base) option allows a custom location to be set. For safer, more reproducible builds, you can optionally specify a URL together with a cryptographic hash of its content. For example: ~~~yaml snapshot: url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/12/0.yaml size: 499143 sha256: 781ea577595dff08b9c8794761ba1321020e3e1ec3297fb833fe951cce1bee11 ~~~ `size` is the number of bytes in the file and `sha256` is the file's SHA256 hash.

# Stack and Visual Studio Code [Visual Studio Code](https://code.visualstudio.com/) (VS Code) is a popular source code editor, and ['Haskell'](https://marketplace.visualstudio.com/items?itemName=haskell.haskell) is an extension for VS Code that is popular with Haskell coders. The 'Haskell' extension can be used with Stack but there are some things to be aware of, set out below. ## GHCup The separate [GHCup](https://www.haskell.org/ghcup/) project provides a tool that can be used to install various tools useful for developing Haskell projects. Those tools include: * GHC, * HLS (see further below), * MSYS2 (on Windows; see the developing on Windows [documentation](developing_on_windows.md)), * Stack, and * Cabal (the tool). Stack itself can be used to install GHC and MSYS2. Stack can also be used to upgrade, or downgrade, Stack. GHCup can configure Stack so that if Stack needs a version of GHC, GHCup takes over obtaining and installing that version. By default, the script to install GHCup (which can be run more than once) configures Stack in that way. For further information about how GHCup configures Stack, see the GHC installation customisation [documentation](../configure/customisation_scripts.md#ghc-installation-customisation). On Windows, GHCup has the capability of using the Stack-supplied MSYS2 rather than installing a duplicate copy. ## HLS The VS Code extension makes use of [HLS](https://github.com/haskell/haskell-language-server) (the Haskell Language Server). To work, HLS has to be built with the same version of GHC that it will support. That is, a version of HLS is required for each version of GHC in use. It is possible that the most recent versions of GHC are not supported by HLS. VS Code with the 'Haskell' extension can be configured in a number of ways: === "GHCup manages HLS" The VS Code extension's settings (under 'Haskell: Manage HLS') allow a user to specify that the extension should use GHCup, to download and install the versions of HLS that it needs. If GHCup manages versions of HLS, versions of GHC can be managed in a number of ways: === "Stack manages GHC using GHCup" As identified above, GHCup can configure Stack to use GHCup to manage versions of GHC. === "Stack manages GHC directly" It is possible to install GHCup so that it is 'empty' except for the current version of HLS, allow the VS Code extension to use GHCup to manage HLS requirements only, and to disable messages from the extension on start-up that installation of GHC, Cabal (the tool) and/or Stack are also necessary (they are not, if only Stack is being used). To install a version of GHCup that is 'empty' is a little more complicated than a default installation of GHCup. === "Unix-like" The following environment variable must be set before GHCup's installation `sh` script is run: `BOOTSTRAP_HASKELL_MINIMAL`. === "Windows" The second argument to the PowerShell script must be set to `$false`, namely: Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $true,$false There is the possibility of false messages from the extension on start-up that need to be ignored. Those messages can be disabled by [setting the following](https://github.com/haskell/vscode-haskell#setting-a-specific-toolchain) for the VS Code extension: ~~~yaml "haskell.toolchain": { "ghc": null, "cabal": null, "stack": null } ~~~ There can be no differences between the version of GHC that the GHCup-supplied HLS was built with and the version that Stack has installed. For the most part, the versions of HLS provided by GHCup are built with the same versions of GHC that Stack downloads from its default `setup-info` dictionary (see the [`setup-info`](../configure/yaml/non-project.md#setup-info) non-project specific configuration option documentation). Stack's default is to mirror the 'official' binary distributions published by GHC. However, in some cases, it is possible that a GHCup-supplied and GHCup-selected HLS has been built with a different binary distribution of GHC than the one which Stack has installed. ??? question "When have the GHCup- and Stack-supplied GHCs differed?" An example occurred with the release of GHC 9.0.2. For some Linux users (Debian 9 and Fedora 27), the version of GHC 9.0.2 linked on GHC’s download [web page](https://www.haskell.org/ghc/download_ghc_9_0_2.html) was broken. The GHC developers made alternative ‘9.0.2a’ versions available. For a while, Stack referred to the versions published by GHC on its download web page while the GHCup-supplied versions of HLS were built using alternative versions. This incompatibility led to problems. It was resolved by Stack's default also being changed to refer to the '9.0.2a' versions. Where Stack has already installed GHC 9.0.2, it is necessary to delete GHC 9.0.2 from the `stack path --programs` directory. This will cause Stack to reinstall the alternative version, when it first needs GHC 9.0.2. Stack should distinguish what it builds with the alternative from what it has built, and cached, with the original GHC 9.0.2. === "Stack uses a GHCup-supplied GHC" GHCup is used to manage versions of GHC and Stack is configured to use the version of GHC on the PATH. That is, GHCup is used to install a version of GHC on the PATH. Stack is configured to make use of that version, by making use of Stack's `install-ghc` option (which needs to be disabled) and Stack's `system-ghc` option (which needs to be enabled). For further information about these options, see the [`install-ghc`](../configure/yaml/non-project.md#install-ghc) documentation and the [`system-ghc`](../configure/yaml/non-project.md#system-ghc) documentation. Each time that a snapshot is used that references a different version of GHC, then GHCup must be used to install it (if GHCup has not already installed that version). For example, to use `snapshot: lts-23.24` (GHC 9.8.4), the command `ghcup install ghc 9.8.4` must have been used to install GHC 9.8.4. That may be a minor inconvenience for some people, as one the primary benefits of Stack over other tools for building Haskell code has been that Stack automatically ensures that the necessary version of GHC is available. === "User manages HLS" By default, the VS Code extension uses tools that are in the PATH. If the VS Code extension is set not to use GHCup, its user needs to ensure that each version of HLS that the extension needs is on the PATH. ### Cradle HLS may need a 'cradle' - an [`hie.yaml` file](https://hackage.haskell.org/package/hie-bios#stack) - in the project's root directory in order to work well. The [`gen-hie` tool](https://hackage.haskell.org/package/implicit-hie) can help generate such a cradle. ### Tips It has been suggested that a project must have been successfully built before the VS code extension (and HLS) is first activated on the project, for HLS to work reliably. stack-3.7.1/doc/topics/stack_root.md0000644000000000000000000003211114765330073015563 0ustar0000000000000000
# Stack root The Stack root is a directory where Stack stores important files. On Unix-like operating systems and Windows, Stack can be configured to follow the XDG Base Directory Specification if the environment variable `STACK_XDG` is set to any non-empty value. However, Stack will ignore that configuration if the Stack root location has been set on the command line or the `STACK_ROOT` environment variable exists. ## Location The location of the Stack root depends on the operating system, whether Stack is configured to use the XDG Base Directory Specification, and/or whether an alternative location to Stack's default 'programs' directory has been specified. The location of the Stack root can be configured by setting the [`STACK_ROOT`](../configure/environment_variables.md#stack_root) environment variable or using Stack's [`--stack-root`](../configure/global_flags.md#-stack-root-option) option on the command line. === "Unix-like" The Stack root contains snapshot packages; (by default) tools such as GHC, in a `programs` directory; Stack's global [configuration](../configure/yaml/index.md) file (`config.yaml`); and Stack's [`global-projects`](../configure/yaml/index.md) directory. The default Stack root is `~/.stack`. === "Windows" The default Stack root is `$Env:APPDATA\stack`. If the `LOCALAPPDATA` environment variable exists, then the default location of tools is `$Env:LOCALAPPDATA\Programs\stack`. Otherwise, it is the `programs` directory in the Stack root. !!! warning If there is a space character in the `$Env:LOCALAPPDATA` path (which may be the case if the relevant user account name and its corresponding user profile path have a space) this may cause problems with building packages that make use of the GNU project's `autoconf` package and `configure` shell script files. That may be the case particularly if there is no corresponding short name ('8 dot 3' name) for the directory in the path with the space (which may be the case if '8 dot 3' names have been stripped or their creation not enabled by default). If there are problems building, it will be necessary to override the default location of Stack's 'programs' directory to specify an alternative path that does not contain space characters. Examples of packages on Hackage that make use of `configure` are `network` and `process`. On Windows, the length of filepaths may be limited (to [MAX_PATH](https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd)), and things can break when this limit is exceeded. Setting a Stack root with a short path to its location (for example, `C:\sr`) can help. === "Windows (Command Prompt)" The default Stack root is `%APPDATA%\stack`. If the `LOCALAPPDATA` environment variable exists, then the default location of tools is `%LOCALAPPDATA%\Programs\stack`. Otherwise, it is the `programs` directory in the Stack root. !!! warning If there is a space character in the `%LOCALAPPDATA%` path (which may be the case if the relevant user account name and its corresponding user profile path have a space) this may cause problems with building packages that make use of the GNU project's `autoconf` package and `configure` shell script files. That may be the case particularly if there is no corresponding short name ('8 dot 3' name) for the directory in the path with the space (which may be the case if '8 dot 3' names have been stripped or their creation not enabled by default). If there are problems building, it will be necessary to override the default location of Stack's 'programs' directory to specify an alternative path that does not contain space characters. Examples of packages on Hackage that make use of `configure` are `network` and `process`. On Windows, the length of filepaths may be limited (to [MAX_PATH](https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd)), and things can break when this limit is exceeded. Setting a Stack root with a short path to its location (for example, `C:\sr`) can help. === "XDG Base Directory Specification" The Stack root is `/stack`. If the `XDG_DATA_HOME` environment variable does not exist, the default is `~/.local/share/stack` on Unix-like operating systems and `%APPDATA%\stack` on Windows. The location of `config.yaml` is `/stack`. If the `XDG_CONFIG_HOME` environment variable does not exist, the default is `~/.config/stack` on Unix-like operating systems and `%APPDATA%\stack` on Windows. This approach treats: * the project-level configuration file that is common to all projects without another such file in their project directory or its ancestor directories as _data_ rather than as part of Stack's own _configuration_; * the snapshots database as essential data rather than as non-essential data that would be part of a _cache_, notwithstanding that Stack will rebuild that database as its contents are needed; and * the Pantry store as essential data rather than as non-essential data that would be part of a _cache_, notwithstanding that Stack will download the package index and rebuild the store if it is absent. An alternative to the default location of tools such as GHC can be specified with the [`local-programs-path`](../configure/yaml/non-project.md#local-programs-path) configuration option. The location of the Stack root is reported by command: ~~~text stack path --stack-root ~~~ The full path of Stack's global configuration file is reported by command: ~~~text stack path --global-config ~~~ The location of tools such as GHC for the current platform is reported by command: ~~~text stack path --programs ~~~ ## Contents The contents of the Stack root depend on the operating system, whether Stack is configured to use the XDG Base Directory Specification, and/or whether an alternative location to Stack's default 'programs' directory has been specified. === "Unix-like" The Stack root contains snapshot packages; (by default) tools such as GHC, in a `programs` directory; Stack's global [configuration](../configure/yaml/index.md) file (`config.yaml`); and Stack's [`global-projects`](../configure/yaml/index.md) directory. === "Windows" The Stack root contains snapshot packages; Stack's global [configuration](../configure/yaml/index.md) file (`config.yaml`); and Stack's [`global-projects`](../configure/yaml/index.md) directory. The default location of tools such as GHC and MSYS2 is outside of the Stack root. === "XDG Base Directory Specification" If Stack is following the XDG Base Directory Specification, the Stack root contains what it would otherwise contain for the operating system, but Stack's global configuration file (`config.yaml`) may be located elsewhere. ### `config.yaml` This is Stack's global configuration file. For further information, see the documentation for non-project specific [configuration](../configure/yaml/non-project.md#non-project-specific-configuration). If the file is deleted, and Stack needs to consult it, then Stack will create a file with default contents. ### `stack.sqlite3` This is a 'user' database that Stack uses to cache certain information. The associated lock file is `stack.sqlite3.pantry-write-lock`. ### `.stack-work` directory (optional) Stack can build when there is no project-level configuration file (including one in the `global-project` directory of the Stack root); for example, as a result of a [`stack script`](../commands/script_command.md) command (at the command line or in a [Stack interpreter options comment](scripts.md) in a Haskell script file). When it does so, the directory corresponding to a project directory is the Stack root. Stack will create its work directory, named `.stack-work` by default, in the Stack root. If the work directory is deleted, and Stack needs that work directory, then Stack will recreate it. ### `global-project` directory This contains: * an explanation of the directory (`README.txt`); * the project-level configuration file (`stack.yaml`) for the global project and its associated lock file (`stack.yaml.lock`); and * if created, Stack's working directory (`.stack-work`) for the global project. If the project-level configuration file is deleted, and Stack needs to consult it, then Stack will recreate the contents of the directory. ### `pantry\hackage` directory This contains a local cache of the package index. If the contents of the directory are deleted, and Stack needs to consult the package index, then Stack will seek to download the latest package index. !!! info Stack depends on package `pantry` which, in turn, depends on package `hackage-security`. The latter handles the local cache of the package index. The type `CacheLayout` represents the location of the files that are cached. `pantry` uses `cabalCacheLayout :: CacheLayout`, the layout that Cabal (the tool) uses. That is what specifies the names of the files used to cache the package index, including `00-index.tar` and `00-index.tar.gz`. ### `pantry` directory This contains: * the Pantry database used by Stack (`pantry.sqlite3`) and its associated lock file (`pantry.sqlite2.pantry-write-lock`). If the database is deleted, and Stack needs to consult it, then Stack will seek to create and initialise it. The database is initialised with information from the package index; and * a database of package versions that come with each version of GHC (`global-hints-cache.yaml`). ### `programs` directory This contains a directory for the platform. That directory contains for each installed Stack-supplied tool: * the archive file for the tool. This can be deleted; * a file indicating the tool is installed (`.installed`); and * a directory for the tool. To remove a Stack-supplied tool, delete all of the above. If Stack needs a Stack-supplied tool and it is unavailable, then Stack will seek to obtain it. ### `scripts` directory (optional) If the `--compile` or `--optimize` and `--use-root` flags are used with the [`stack script`](../commands/script_command.md) command, then this contains: * script-specific locations, each containing all the compilation outputs (inclduing the executable) generated by the command. If the `scripts` directory, or a script-specific location within it, is deleted, and Stack needs that directory, then Stack will recreate it. ### `setup-exe-cache` directory This contains a directory for the platform. That directory contains, for each version of GHC (an associated version of Cabal (the library)) that Stack has used, an executable that Stack uses to access Cabal (the library). If the contents of the directory are deleted, and Stack needs the executable, then Stack will seek to rebuild it. ### `setup-exe-src` directory See the documentation for the [`setup-exe-cache` directory](#setup-exe-cache-directory). This contains the two source files (`setup-.hs` and `setup-shim-.hs`) that Stack uses to build the executable. If the contents of the directory are deleted, and Stack needs the executable, then Stack will recreate them. The hash in the names of the source files is a hash of arguments passed to GHC when building the executable and the contents of the two source files. The content of the `setup-.hs` file is the familiar: ~~~haskell import Distribution.Simple main = defaultMain ~~~ The content of the `setup-shim-.hs` file uses `main` except when the executable is called with arguments `repl` and `stack-initial-build-steps`. Then Stack uses Cabal (the library) to create the autogenerated files for every configured component. Stack's `stack ghci` or `stack repl` commands call the executable with those arguments. ### `snapshots` directory This contains a directory for each snapshot that Stack creates when building immutable dependencies of projects. If the contents of the directory are deleted, and the snapshot is not available to Stack when it builds, then Stack will recreate the snapshot. ### `templates` directory This contains a `.hsfile` for each project template that Stack has used. For further information, see the [`stack templates`](../commands/templates_command.md) command documentation. If the contents of the directory are deleted, an Stack needs a project template, then Stack will seek to download the template. ### `upload` directory This may contain saved credentials for uploading packages to Hackage (`credentials.json`). stack-3.7.1/doc/topics/stack_work.md0000644000000000000000000001431414734007300015555 0ustar0000000000000000
# Stack work directories Stack work directories are directories within a local project or package directory in which Stack stores files created during the build process. Stack can be used without an understanding of the content of those directories. In particular, the [`stack exec`](../commands/exec_command.md) command sets up an environment where relevant subdirectories of the project Stack work directory are on the PATH. ## Naming By default, Stack work directories are named `.stack-work`. The name can be overidden by: * the use of the [`STACK_WORK` environment variable](../configure/environment_variables.md#stack_work); * the [`work-dir`](../configure/yaml/non-project.md#work-dir) non-project specific configuration option; or * the [`--work-dir`](../configure/global_flags.md#-work-dir-option) command line option. Given the location of Stack work directories, the name of the work directories must be a relative path to a directory. ## Location If the work directory does not already exist, it will be created by the [`stack build`](../commands/build_command.md) command as a subdirectory of each project package directory and, if different, the project directory. ## Project package Stack work directory The Stack work directory for a project package will contain a `dist` directory. This directory will contain a path to a directory containing: * a `build` directory; * a `package.conf.inplace` directory; * a `stack-build-caches` directory; * a `build-lock` file; * a `setup-config` file; * a `stack-cabal-mod` file. This file is used by Stack only for its modification time; * a `stack-project-root` file. This file contains an absolute path to the project root directory; and * a `stack-setup-config-mod` file. This file is used by Stack only for its modification time. The directory, relative to the project package directory or the project directory, is the one reported by [`stack path --dist-dir`](../commands/path_command.md). === "Unix-like" On Unix-like operating systems, the path to the directory is a directory named after the platform (including Stack's classification of variants of Linux distributions) followed by a directory named after the GHC version. === "Windows" On Windows, the path to the directory is an eight-character hash of the path that applies on Unix-like operating systems. ## Project Stack work directory The Stack work directory for a project will contain a `install` directory. This directory will contain a path to a directory containing: * a `bin` directory, containing built executable files; * a `doc` directory, containing a directory for each project package. This is the directory reported by [`stack path --local-doc-root`](../commands/path_command.md); * if the [`stack hpc`](../commands/hpc_command.md) command is used, a `hpc` directory. This is the directory reported by [`stack path --local-hpc-root`](../commands/path_command.md); * a `lib` directory, containing a directory named after the platform and the GHC version and, within that, a directory for each project package; * a `pkgdb` directory. This is the directory reported by [`stack path --local-pkg-db`](../commands/path_command.md); * a `stack.sqlite3` file; and * a `stack.sqlite3.pantry-write-lock` file. The directory is the one reported by [`stack path --local-install-root`](../commands/path_command.md). === "Unix-like" On Unix-like operating systems, the path to the directory is a directory named after the platform (including Stack's classification of variants of Linux distributions) followed by a directory named after a SHA 256 hash (see further below) followed by a directory named after the version number of GHC. The SHA 256 hash is a hash of the following information: * the path to the specified compiler; * the information about the compiler provided by `ghc --info`; * the options that Stack passes to GHC for package that is not a project package; and * information about the immutable dependencies: their location, whether or not Haddock documentation is to be built, their flags, their GHC options, and their Cabal configuration options. The options that Stack passes to GHC for a package that is not a project package depend on: * the specification of [profiling](../commands/build_command.md#flags-affecting-ghcs-behaviour); * the specification of [stripping](../commands//build_command.md#flags-affecting-ghcs-behaviour); and * if [`apply-ghc-options: everything`](../configure/yaml/non-project.md#apply-ghc-options) is specified, any GHC command line options specified on the command line. !!! note As a consequence, the path reported by the following commands will differ (and similarly for the paths established by the [`stack exec`](../commands/exec_command.md) command): ~~~text stack path --local-install-root stack --profile path --local-install-root stack --no-strip path --local-install-root stack --profile --no-strip path --local-install-root ~~~ === "Windows" On Windows, the path to the directory is an eight-character hash of the path that applies on Unix-like operating systems. Following a `stack ghci` or `stack repl` command, the Stack work directory for a project will contain a `ghci` directory. This directory will contain paths to `cabal_macos.h` files that are generated automatically by Cabal. !!! note Haskell Language Server makes use of the `stack ghci` command to obtain information. If the [`stack hoogle`](../commands/hoogle_command.md) command is used, the Stack work directory for a project will contain a `hoogle` directory. This directory will contain a directory being the one reported by [`stack path --local-hoogle-root`](../commands/path_command.md). The naming of the path to the directory is same as for the path to the directory in the `install` directory. stack-3.7.1/doc/topics/stack_yaml_vs_cabal_package_file.md0000644000000000000000000001677615023557531022067 0ustar0000000000000000
# stack.yaml versus package.yaml versus a Cabal file What is the difference between a `stack.yaml` file, a `package.yaml` file and a Cabal file (named `.cabal`)? This page aims to make that clear. In short: * `stack.yaml` contains project-level configuration for Stack, and may contain project-specific options and non-project-specific options. * `package.yaml` contains a description of a package in the [Hpack](https://github.com/sol/hpack) format. Hpack, including Stack's built-in version, uses the file to create a Cabal file. * a Cabal file also contains a description of a package, but in the format used by Cabal. ## package.yaml versus a Cabal file Why two different formats to describe packages? Hpack is considered to have some advantages over the underlying Cabal format, which are explained its project repository. They include that the Hpack format supports YAML syntax and the automatic generation of the lists of `exposed-modules` used in the Cabal format. The remainder of this page will focus on the difference between a `stack.yaml` file and a package description file. ## Package versus project Stack is a tool for building Haskell code and it uses Cabal, a build system. Cabal defines the concept of a _package_. A package has: * A name and version * optionally, one library * optionally, one or more executables * A Cabal file (or, as mentioned above, an [Hpack](https://github.com/sol/hpack) `package.yaml` file that generates a Cabal file) * And a bunch more There is a one-to-one correspondence between a package and a Cabal file. Stack defines a new concept called a _project_. A project has: * A snapshot _resolver_ (more on this later) * Extra dependencies on top of the snapshot * Optionally, one or more local Cabal packages * Flag and GHC options configurations * And a bunch more Stack configuration Often you will have a project that defines only one local Cabal package that you are working on. If you need to specify a dependency, a source of confusion can be why you need to specify it both in the `stack.yaml` file _and_ in the Cabal file. To explain, let's take a quick detour to talk about snapshots and how Stack resolves dependencies. ## Snapshots and resolvers Stack follows a rule that says, for any project, there is precisely one version of each package available. Obviously, for many packages there are _many_ versions available in the world. But when resolving a `stack.yaml` file, Stack requires that you have chosen a specific version for each package available. The most common means by which this set of packages is defined is via a snapshot provided by Stackage. For example, if you go to the page , you will see a list of 3,212 packages at specific version numbers. When you then specify `snapshot: lts-23.24` or, alternatively, `resolver: lts-23.24`, you're telling Stack to use those package versions in resolving dependencies down to specific versions of packages. Sometimes a snapshot doesn't have all of the packages that you want. Or you want a different version of a package. Or you want to work on a local modification of a package. In all of those cases, you can add more configuration data to your `stack.yaml` file to override the values it received from your [`snapshot`](../configure/yaml/project.md#snapshot) or [`resolver`](../configure/yaml/project.md#resolver) setting. At the end of the day, each of your projects will end up with some way of resolving a package name into a specific version of that package. ## Why specify dependencies twice? The package `acme-missiles` is not included in any Stackage snapshots. When you add something like this to your `stack.yaml` file: ~~~yaml extra-deps: - acme-missiles-0.3 ~~~ what you're saying to Stack is: "if at any point you find that you need to build the `acme-missiles` package, please use version `0.3`". You are _not_ saying "please build `acme-missiles` now." You are also not saying "my package depends on `acme-missiles`." You are simply making it available should the need arise. When you add to your `package.yaml` file: ~~~yaml dependencies: - acme-missiles ~~~ or, alternatively, you add directly to your Cabal file: ~~~yaml build-depends: acme-missiles ~~~ you're saying "this package requires that `acme-missiles` be available." Since `acme-missiles` doesn't appear in your snapshot, without also modifying your `stack.yaml` to mention it via `extra-deps`, Stack will complain about the dependency being unavailable. You may challenge: but why go through all of that annoyance? Stack knows what package I want, why not just go grab it? The answer is that, if Stack just grabbed `acme-missiles` for you without it being specified in the `stack.yaml` somehow, you'd lose reproducibility. How would Stack know which version to use? It may elect to use the newest version, but if a new version is available in the future, will it automatically switch to that? Stack's core philosophy is that build plans are always reproducible. The purpose of the `stack.yaml` file is to define an immutable set of packages. No matter when in time you use it, and no matter how many new release happen in the interim, the build plan generated should be the same. (There is, however, at least one hole in this theory today, which is Hackage revisions. When you specify `extra-deps: [acme-missiles-0.3]`, it doesn't specify which revision of the Cabal file to use, and Stack will just choose the latest. Stack has the ability to specify exact revisions of Cabal files, but this isn't enforced as a requirement, because it is so different from the way most people work with packages.) And now, how about the other side: why doesn't Stack automatically add `acme-missiles` to `build-depends` in your Cabal file if you add it as an extra-dep? There are a surprising number reasons for this: * The Cabal specification doesn't support anything like that * There can be multiple packages in a project, and how do we know which package actually needs the dependency? * There can be multiple components (libraries, executable, etc) in a package, and how do we know which of those actually needs the dependency? * The dependency may only be conditionally needed, based on flags, operating system, or architecture. As an extreme example, we wouldn't want a Linux-only package to be built by force on Windows. While for simple use cases it seems like automatically adding dependencies from the Cabal file to the `stack.yaml` file or vice-versa would be a good thing, it breaks down immediately for any semi-difficult case. Therefore, Stack requires you to add it to both places. And a final note, in case it wasn't clear. The example above used `acme-missiles`, which is not in Stackage snapshots. If, however, you want to depend on a package already present in the snapshot you've selected, there's no need to add it explicitly to your `stack.yaml` file: it's already there implicitly via the `snapshot` setting. This is what you do the majority of the time, such as when you add `vector` or `mtl` as a `build-depends` value. ## Should I check-in automatically generated Cabal files? Yes, you should. This recommendation was changed in [issue #5210](https://github.com/commercialhaskell/stack/issues/5210). Please see the discussion there. stack-3.7.1/doc/topics/travis_ci.md0000644000000000000000000001462014651506554015406 0ustar0000000000000000
# Travis CI This page documents how to use Stack on [Travis CI](https://travis-ci.org/). We assume you have basic familiarity with Travis. We provide two fully baked example files ready to be used on your projects: * [The simple Travis configuration](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/resources/travis-simple.yml) is intended for applications that do not require multiple GHC support or cross-platform support. It builds and tests your project with just the settings present in your `stack.yaml` file. * [The complex Travis configuration](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/resources/travis-complex.yml) is intended for projects that need to support multiple GHC versions and multiple OSes, such as open source libraries to be released to Hackage. It tests against cabal-install, as well as Stack on Linux and macOS. The configuration is significantly more involved to allow for all of this branching behavior. !!! note It is likely going to be necessary to modify this configuration to match the needs of your project, such as tweaking the build matrix to alter which GHC versions you test against, or to specify GHC-version-specific `stack.yaml` files if necessary. Don't be surprised if it doesn't work the first time around. See the multiple GHC section below for more information. Each of these configurations is ready to be used immediately, just copy-paste the content into the `.travis.yml` file in the root or your repo, enable Travis on the repo, and you're good to go. You may also be interested in using AppVeyor, which supports Windows builds, for more cross-platform testing. There's a [short blog post available on how to do this](http://www.snoyman.com/blog/2016/08/appveyor-haskell-windows-ci), or just copy in [the appveyor.yml file](https://raw.githubusercontent.com/commercialhaskell/stack/stable/doc/resources/appveyor.yml) The rest of this document explains the details of common Travis configurations for those of you who want to tweak the above configuration files or write your own. *Note:* both Travis and Stack infrastructures are actively developed. We try to document best practices at the moment. ## Container infrastructure For Stack on Travis to be practical, we must use caching. Otherwise build times will take an incredibly long time, about 30 minutes versus 3-5. Caching is currently available only for [container-based Travis infrastructure](http://docs.travis-ci.com/user/workers/container-based-infrastructure/). Shortly we have to add ~~~yaml sudo: false # Caching so the next build will be fast too. cache: directories: - $HOME/.stack ~~~ To the `.travis.yml`. This however restricts how we can install GHC and Stack on the Travis machines. ## Installing Stack Currently there is only one reasonable way to install Stack: fetch precompiled binary from the GitHub. ~~~yaml before_install: # Download and unpack the stack executable - mkdir -p ~/.local/bin - export PATH=$HOME/.local/bin:$PATH - travis_retry curl -L https://get.haskellstack.org/stable/linux-x86_64.tar.gz | tar xz --wildcards --strip-components=1 -C ~/.local/bin '*/stack' ~~~ ## Installing GHC There are two ways to install GHC: - Let Stack download GHC - Install GHC using [apt plugin](http://docs.travis-ci.com/user/apt/) See the above scripts for an example of the first option (letting Stack download GHC). Here, we will explain the second option. With single GHC the situation is simple: ~~~yaml before_install: # Install stack as above # ... # Configure stack to use the system GHC installation - stack config set system-ghc --global true - export PATH=/opt/ghc/7.10.2/bin:$PATH addons: apt: sources: - hvr-ghc packages: - ghc-7.10.2 ~~~ ### Multiple GHC - parametrised builds Travis apt plugin doesn't yet support installing apt packages dynamically (https://github.com/travis-ci/travis-ci/issues/4291). That for we need to write a bit repetitive `.travis.yml`. Also for different GHC versions, you probably want to use different `stack.yaml` files. ~~~yaml # N.B. No top-level env: declaration! matrix: include: - env: GHCVER=7.8.4 STACK_YAML=stack.yaml addons: apt: sources: - hvr-ghc packages: - ghc-7.8.4 - env: GHCVER=7.10.1 STACK_YAML=stack-7.10.yaml addons: apt: sources: - hvr-ghc packages: - ghc-7.10.1 - env: GHCVER=head STACK_YAML=stack-head.yaml addons: apt: sources: - hvr-ghc packages: - ghc-head allow_failures: - env: GHCVER=head STACK_YAML=stack-head.yaml before_install: # ghc - export PATH=/opt/ghc/$GHCVER/bin:$PATH ~~~ Especially to use ghc `HEAD` you need to pass `--skip-ghc-check` option to Stack. ## Running tests After the environment setup, actual test running is simple: ~~~yaml script: - stack --no-terminal --skip-ghc-check test ~~~ In case you're wondering: we need `--no-terminal` because stack does some fancy sticky display on smart terminals to give nicer status and progress messages, and the terminal detection is broken on Travis. ## Other details Some Stack commands will run for long time (when cache is cold) without producing any output. To avoid timeouts, use the built in [travis_wait](https://docs.travis-ci.com/user/common-build-problems/#Build-times-out-because-no-output-was-received). ~~~yaml install: - travis_wait stack --no-terminal --skip-ghc-check setup - travis_wait stack --no-terminal --skip-ghc-check test --only-snapshot ~~~ ## Examples - [futurice/fum2github](https://github.com/futurice/fum2github/blob/master/.travis.yml) - [haskell-distributed/cloud-haskell](https://github.com/haskell-distributed/cloud-haskell/blob/master/.travis.yml) - [simonmichael/hledger](https://github.com/simonmichael/hledger/blob/master/.travis.yml) - [fpco/wai-middleware-crowd](https://github.com/fpco/wai-middleware-crowd/blob/master/.travis.yml) - [commercialhaskell/all-cabal-hashes-tool](https://github.com/commercialhaskell/all-cabal-hashes-tool/blob/master/.travis.yml) stack-3.7.1/doc/tutorial/building_existing_projects.md0000644000000000000000000001334114765330073021401 0ustar0000000000000000
# 5. Building existing projects Alright, enough playing around with simple projects. Let's take an open source package and try to build it. We'll be ambitious and use [yackage](https://hackage.haskell.org/package/yackage), a local package server using [Yesod](http://www.yesodweb.com/). To get the code, we'll use the `stack unpack` command from the root directory for all our Haskell projects: ~~~text stack unpack yackage Unpacked yackage-0.8.1 to /yackage-0.8.1/ ~~~ You can also unpack to the directory of your liking instead of the current one by issuing the command: ~~~text stack unpack yackage --to ~~~ This will create a `yackage-0.8.1` directory inside ``. We will change to that directory, with the command: ~~~text cd yackage-0.8.1 ~~~ ## The `stack init` command This new directory does not have a `stack.yaml` file, so we need to make one first. We could do it by hand, but let's be lazy instead with the `stack init` command: ~~~text stack init # init output ... ~~~ `stack init` does quite a few things for you behind the scenes: * Finds all of the Cabal files in your current directory and subdirectories (unless you use `--ignore-subdirs`) and determines the packages and versions they require * Finds the best combination of snapshot and package flags that allows everything to compile with minimum external dependencies * It tries to look for the best matching snapshot from latest LTS, latest nightly, other LTS versions in that order Assuming it finds a match, it will write your `stack.yaml` file, and everything will work. !!! note The `yackage` package does not currently support Hpack, but you can also use `hpack-convert` should you need to generate a `package.yaml` file. ### Excluded Packages Sometimes multiple packages in your project may have conflicting requirements. In that case `stack init` will fail, so what do you do? You could manually create `stack.yaml` by omitting some packages to resolve the conflict. Alternatively you can ask `stack init` to do that for you by specifying `--omit-packages` flag on the command line. Let's see how that works. To simulate a conflict we will use `acme-missiles-0.3` in `yackage` and we will also copy `yackage.cabal` to another directory and change the name of the file and package to `yackage-test`. In this new package we will use `acme-missiles-0.2` instead. Let's see what happens when we command `stack init` again: ~~~text stack init --force --omit-packages # init failure output ... ~~~ Looking at `stack.yaml`, you will see that the excluded packages have been commented out under the `packages` key. In case wrong packages are excluded you can uncomment the right one and comment the other one. Packages may get excluded due to conflicting requirements among user packages or due to conflicting requirements between a user package and the snapshot compiler. If all of the packages have a conflict with the compiler then all of them may get commented out. When packages are commented out you will see a warning every time you run a command which needs the configuration file. The warning can be disabled by editing the configuration file and removing it. ### Using a specific snapshot Sometimes you may want to use a specific snapshot for your project instead of `stack init` picking one for you. You can do that by using `stack init --snapshot `. You can also init with a compiler snapshot if you do not want to use a Stackage snapshot. That will result in all of your project's dependencies being put under the `extra-deps` section. ### Installing the compiler Stack will automatically install the compiler when you run `stack build` but you can manually specify the compiler by running `stack setup `. ### Miscellaneous and diagnostics _Add selected packages_: If you want to use only selected packages from your project directory you can do so by explicitly specifying the package directories on the command line. _Duplicate package names_: If multiple packages under the directory tree have same name, `stack init` will report those and automatically ignore one of them. _Ignore subdirectories_: By default `stack init` searches all the subdirectories for Cabal files. If you do not want that then you can use `--ignore-subdirs` command line switch. _Cabal warnings_: `stack init` will show warnings if there were issues in reading a Cabal file. You may want to pay attention to the warnings as sometimes they may result in incomprehensible errors later on during dependency solving. _Package naming_: If the `name` field defined in a Cabal file does not match with the Cabal file name then `stack init` will refuse to continue. _User warnings_: When packages are excluded or external dependencies added Stack will show warnings every time the configuration file is loaded. You can suppress the warnings by editing the configuration file and removing the warnings from it.

# 4. Building your project The [`stack build`](../commands/build_command.md) command is the heart of Stack. It is the engine that powers building your code, testing it, getting dependencies, and more. Much of the remainder of this getting started guide will cover its features. !!! note Using the `build` command twice with the same options and arguments should generally do nothing (besides things like rerunning test suites), and should, in general, produce a reproducible result between different runs. ## Adding dependencies A Haskell package often depends on code exposed by other Haskell packages. Let's say we decide to modify our existing `helloworld` package source code to use a new library, the one provided by the [`text`](https://hackage.haskell.org/package/text) package. We can modify `src/Lib.hs` so that its contents are as follows (click :material-plus-circle: to learn more): ~~~haskell {-# LANGUAGE OverloadedStrings #-} -- (1)! module Lib ( someFunc ) where import qualified Data.Text.IO as T -- (2)! someFunc :: IO () someFunc = T.putStrLn "someFunc" --(3)! ~~~ 1. Enables overloaded string literals. String literals now have type `(IsString a) => a`. 2. The module is exposed by the library of the `text` package. 3. `Data.Text.IO.putStrLn :: Text -> IO ()`. If we command: ~~~text stack build ~~~ Stack will report Stack error [S-7282] during the build, with output like the following: ~~~text ... Building library for helloworld-0.1.0.0.. [1 of 2] Compiling Lib [Source file changed] src\Lib.hs:7:1: error: Could not load module ‘Data.Text.IO’ It is a member of the hidden package ‘text-2.0.2’. Perhaps you need to add ‘text’ to the build-depends in your .cabal file. Use -v (or `:set -v` in ghci) to see a list of the files searched for. | 7 | import qualified Data.Text.IO as T | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Error: [S-7282] Stack failed to execute the build plan. While executing the build plan, Stack encountered the error: [S-7011] While building package helloworld-0.1.0.0 (scroll up to its section to see the error) using: ... Process exited with code: ExitFailure 1 ~~~ The error `Could not load module ...` means that the package exposing the module in question is not available. To tell Stack that the `text` package is a dependency of the `helloworld` package, you need to update the package description file (`package.yaml`). Specifically, you need to add `text` under the `dependencies` key, like this: ~~~yaml dependencies: - base >= 4.7 && < 5 - text # added ~~~ Now, if we command: ~~~text stack build ~~~ we should get a successful result. The output means that the `text` package was downloaded, configured, built, and locally installed. Once that was done, we moved on to building our project package (`helloworld`). At no point did we need to ask Stack to build dependencies — it does so automatically. ## Listing dependencies Let's have Stack add a few more dependencies to our project. First, we'll include two new packages in the `dependencies` section for our library in our `package.yaml`: ~~~yaml dependencies: - base >= 4.7 && < 5 - text - filepath # added - containers # added ~~~ After adding these two dependencies, we can again command: ~~~text stack build ~~~ to have them downloaded, configured, built, and locally installed. To find out which versions of these packages Stack installed, we can command: ~~~text stack ls dependencies ~~~ ## Packages not in the snapshot The packages `text`, `filepath` and `containers` have something in common: they are all provided with GHC (referred to as GHC boot packages). Let's try a dependency on a more off-the-beaten-track package: the joke [acme-missiles](http://www.stackage.org/package/acme-missiles) package. We can further modify `src/Lib.hs` so that its contents are as follows: ~~~haskell module Lib ( someFunc ) where import Acme.Missiles ( launchMissiles ) someFunc :: IO () someFunc = launchMissiles ~~~ As before, to tell Stack that the `acme-missiles` package is a dependency of the `helloworld` package, we must update the package description file (`package.yaml`). The relevant part of that file now looks like this: ~~~yaml dependencies: - base >= 4.7 && < 5 - text - filepath - containers - acme-missiles # added ~~~ However, if we command: ~~~text stack build ~~~ Stack will report Stack error [S-4804] during the build, with output like the following: ~~~text Error: [S-4804] Stack failed to construct a build plan. While constructing the build plan, Stack encountered the following errors. The 'Stack configuration' refers to the set of package versions specified by the snapshot (after any dropped packages, or pruned GHC boot packages; if a boot package is replaced, Stack prunes all other such packages that depend on it) and any extra-deps: In the dependencies for helloworld-0.1.0.0: * acme-missiles needed, but no version is in the Stack configuration (latest matching version is 0.3). The above is/are needed since helloworld is a build target. Some different approaches to resolving some or all of this: * Recommended action: try adding the following to your extra-deps in ...\helloworld\stack.yaml (project-level configuration): - acme-missiles-0.3@sha256:2ba66a092a32593880a87fb00f3213762d7bca65a6 87d45965778deb8694c5d1,613 ~~~ The error message explains that Stack was unable to construct a build plan and why: the package `acme-missiles` was needed but no version of that package is in the set of package versions specified by the snapshot. Stack makes a suggestion to fix that. This brings us to the next major topic in using Stack. ## Extending snapshots A snapshot specifies a version of GHC and a set of package versions chosen to work well together. However, sometimes you will want to use package versions that are not specified by the snapshot. That may be because the package is not in the snapshot or because a different version of the package is in the snapshot. Remember above when `stack new` selected some [LTS snapshot](https://github.com/commercialhaskell/lts-haskell#readme) for us? That defined our build plan and available packages. When we tried using the `text` package, it just worked, because it was part of the LTS *package set*. We have updated the description of the `helloworld` package (in `package.yaml`) to specify that it depends on the `acme-missiles` package, but `acme-missiles` is not a member of the set of package versions specified by the snapshot. So building failed. To add a version of `acme-missiles` to the available package versions, we'll use the `extra-deps` key in Stack's project-level configuration file (`stack.yaml`). That key defines extra package versions, not present in the snapshot, that will be needed as dependencies. You can add this like so: ~~~yaml extra-deps: - acme-missiles-0.3 # not in the LTS snapshot ~~~ Now, if we command: ~~~text stack build ~~~ we should get a successful result. ## Stackage snapshots With that out of the way, let's dig a little bit more into these snapshots. We mentioned the LTS snapshots, and you can get information about it at [https://www.stackage.org/lts](https://www.stackage.org/lts), including: * The appropriate value (`lts-23.24`, as is currently the latest LTS) * The GHC version used * A full list of all packages versions available in this snapshot * The ability to perform a Hoogle search on the packages in this snapshot * A [list of all modules](https://www.stackage.org/lts/docs) in a snapshot, which can be useful when trying to determine which package to add to your `package.yaml` file. You can also see a [list of all available snapshots](https://www.stackage.org/snapshots). You'll notice two flavors: LTS (for "Long Term Support") and Nightly. You can read more about them on the [LTS Haskell GitHub page](https://github.com/commercialhaskell/lts-haskell#readme). If you're not sure which to use, start with LTS Haskell (which Stack will lean towards by default as well). ## Snapshots and GHC versions As mentioned, a snapshot specifies a version of GHC as well as a set of package versions. ??? question "I want to use a particular version of GHC. What snapshot should I use?" For each supported version of GHC, the Stackage [homepage](https://www.stackage.org/) lists the most recent Stackage snapshot. In most cases, that is the snapshot you should use. ??? question "Can I use a snapshot like `ghc-9.8.4`?" Snapshot `ghc-9.8.4` specifies GHC 9.8.4 and, consequently, the GHC boot packages that come with that compiler. However, the snapshot does not include the many other package versions that will work with that compiler. For a set of those package versions, see the snapshots published by the [Stackage](https://www.stackage.org/) project. Let us try using an older Stackage LTS Haskell snapshot. We will use the LTS 22.43 snapshot with the command: ~~~text stack --snapshot lts-22.43 build ~~~ Stackage LTS Haskell 22.43 specifies GHC 9.6.6. If that version of GHC is not already available, Stack will try to fetch it and install it before starting the rest of the build. ## Specifying a snapshot A snapshot must be specified in Stack's project-level configuration file (`stack.yaml`, by default). For further information, see the [`snapshot`](../configure/yaml/project.md#snapshot) project-specific configuration option documentation. As we have seen, a snapshot can also be specified on the command line. That can be useful in a Continuous Integration (CI) setting. When passed on the command line, you also get some additional "short-cut" versions of snapshots: `--snapshot nightly` will use the newest Nightly snapshot available, `--snapshot lts` will use the newest LTS, and `--snapshot lts-22` will use the newest LTS in the 22.x series. The reason these are only available on the command line and not in your `stack.yaml` file is that using them: 1. Will slow down your build (since Stack then needs to download information on the latest available LTS each time it builds) 2. Produces unreliable results (since a build run today may proceed differently tomorrow because of changes outside of your control) ## Cleaning up your project Stack creates files during the build process and stores those files in directories within a local project or package directory known as [Stack work directories](../topics/stack_work.md). Stack can be used without an understanding of the content of those directories. if you wish, you can clean up files created during the build process for your project using the `stack clean` and `stack purge` commands. ### The `stack clean` command `stack clean` deletes the local working directories containing compiler output. By default, that means the contents of directories in `.stack-work/dist`, for all the `.stack-work` directories within a project. Use `stack clean ` to delete the output for the package _specific-package_ only. ### The `stack purge` command `stack purge` deletes the local stack working directories, including extra-deps, git dependencies and the compiler output (including logs). It does not delete any snapshot packages, compilers or programs installed using `stack install`. This essentially reverts the project to a completely fresh state, as if it had never been built. `stack purge` is a shortcut for `stack clean --full`. stack-3.7.1/doc/tutorial/cabal_flags_and_ghc_options.md0000644000000000000000000001256114765330073021420 0ustar0000000000000000
# 10. Cabal flags and GHC options There are two common ways to affect how a package will be built: with Cabal flags and with GHC options. ## Cabal flags Cabal flags can be set or unset at the command line or as a project-specific Stack option. To set or unset a Cabal flag at the command line, we can use the `--flag` option. The `yackage` package has an `upload` flag that is enabled by default. We can command: ~~~text stack build --flag yackage:-upload ~~~ This means: when compiling the `yackage` package, turn off the `upload` Cabal flag (thus the `-` in `-upload`). Unlike other tools, Stack is explicit about which package's flag you want to change. It does this for two reasons: 1. There's no global meaning for Cabal flags, and therefore two packages can use the same flag name for completely different things. 2. By following this approach, we can avoid unnecessarily recompiling snapshot packages that happen to use a Cabal flag that we're using. You can also change Cabal flag values on the command line for extra-dep and snapshot packages. If you do this, that package will automatically be promoted to an extra-dep, since the build plan is different than what the plan snapshot definition would entail. If you have Cabal flags that you will be setting regularly when building your packages, you can add them to your Stack project-level configuration file (`stack.yaml`). For more information, see the [flags](../configure/yaml/project.md#flags) project-specific configuration option documentation. ## GHC options GHC options can be specified at the command line or as an non-project specific Stack option. At the command line, consider the command: ~~~text stack build --ghc-options="-Wall -Werror" ~~~ or, equivalently: ~~~text stack build --ghc-options=--pedantic ~~~ By default, this will set GHC's `-Wall` and `-Werror` options for all *project packages*. This will not, however, affect other packages at all. This design provides us with reproducible and fast builds. ??? question "Can GHC options for other packages be specified at the command line?" Yes, GHC options can be specified at the command line for all packages or only project packages that are targets. For further information, see the documentation for the [apply-ghc-options](../configure/yaml/non-project.md#apply-ghc-options) non-project specific configuration option. ??? question "What if GHC options specified at the command line apply only to targets?" By changing the default using the [apply-ghc-options](../configure/yaml/non-project.md#apply-ghc-options) configuration option, it is possble to specify that GHC options at the command line apply only to project packages that are *targets*. If this is done and you change your targets, the options will no longer apply to other project packages. Let us consider an example from the `wai` repository, which includes the `wai` and `warp` packages, the latter depending on the former. If we command: ~~~text stack build --ghc-options=-O0 wai ~~~ Stack will build all of the dependencies of `wai` (inclduding `warp`) and then build `wai` with all GHC optimizations disabled. Now let's add `warp` as a target. If we command: ~~~text stack build --ghc-options=-O0 wai warp ~~~ this builds the additional dependencies for `warp`, and then builds `warp` with GHC optimizations disabled. Importantly, Stack does not rebuild `wai`, since `wai`'s configuration has not been altered. Now the surprising case. If we command: ~~~text stack build --ghc-options=-O0 warp ~~~ you may expect this to do nothing, as neither `wai` nor `warp` has changed. However, Stack will rebuild `wai` with GHC optimizations enabled again, and then rebuild `warp` (with optimizations disabled) against this newly-built `wai`. The reason is reproducible builds. If we had never built `wai` or `warp` before, trying to build `warp` would require building all of its dependencies, and it would do so with default GHC options (that is, GHC optimizations enabled). These dependencies would include `wai`. So when we command: ~~~text stack build --ghc-options=-O0 warp ~~~ we want Stack's behavior to be unaffected by any previous build steps we took. If you have GHC options that you will be applying regularly when building your packages, you can add them to your Stack project-level configuration file (`stack.yaml`) or (if applicable) to a [global Stack configuration file](../configure/yaml/index.md#project-level-and-global-configuration-files). For more information, see the [ghc-options](../configure/yaml/non-project.md#ghc-options) non-project specific configuration option documentation. ??? question "Can Stack be configured to specify GHC options for specific packages?" Yes, Stack can be configured to specify GHC options for specific packages, either globally or at the project level. For more information, see the [ghc-options](../configure/yaml/non-project.md#ghc-options) non-project specific configuration option documentation. stack-3.7.1/doc/tutorial/executing_commands.md0000644000000000000000000000441314765330073017635 0ustar0000000000000000
# 12. Executing commands We've already used `stack exec` multiple times in this guide. As you've likely already guessed, it allows you to run executables, but with a slightly modified environment. ## The `stack exec` command In particular: `stack exec` looks for executables on Stack's bin paths, and sets a few additional environment variables (like adding those paths to the PATH, and setting `GHC_PACKAGE_PATH`, which tells GHC which package databases to use). If you want to see exactly what the modified environment looks like, try command: ~~~text stack exec env ~~~ The only issue is how to distinguish flags to be passed to Stack versus those for the underlying program. Thanks to the `optparse-applicative` library, Stack follows the Unix convention of `--` to separate these. For example, command: ~~~text stack exec --package stm -- echo I installed the stm package via --package stm ~~~ yields output like: ~~~text Writing the configuration file for the implicit global project to: .../global-project/stack.yaml. Note: You can change the snapshot via the snapshot key there. Using the latest snapshot lts-22.31. I installed the stm package via --package stm ~~~ Flags worth mentioning: * `--package foo` can be used to force a package to be installed before running the given command. * `--no-ghc-package-path` can be used to stop the `GHC_PACKAGE_PATH` environment variable from being set. Some tools — notably Cabal (the tool) — do not behave well with that variable set. You may also find it convenient to use `stack exec` to launch a subshell (substitute `bash` with your preferred shell) where your compiled executable is available at the front of your PATH. Command: ~~~text stack exec bash ~~~ ## The `stack ghc` and `stack runghc` commands You'll sometimes want to just compile (or run) a single Haskell source file, instead of creating an entire Cabal package for it. You can use `stack exec ghc` or `stack exec runghc` for that. As simple helpers, we also provide the `stack ghc` and `stack runghc` commands, for these common cases. stack-3.7.1/doc/tutorial/hello_world_example.md0000644000000000000000000003045014734007355020006 0ustar0000000000000000
# 1. A Hello World example With Stack installed, let's create a new project and walk through the most common Stack commands. In this guide, unless stated otherwise, the working directory is the project's root directory. ## The `stack new` command We'll start off with the [`stack new`](../commands/new_command.md) command to create a new *project* from a project template. We'll use the `new-template` project template. This template is used by default, but in our example we will refer to it expressly. That template will create a project with a package of the same name. So, we need to pick a name for the project that is a valid package name. We'll call our project `helloworld`. ??? question "How do project packages relate to projects?" A project can have one or more packages. Each project package has its own root directory. In the case of a single-package project, the project directory and the package directory can be the same directory. ??? question "What is a valid package name?" A valid package name consists of one or more alphanumeric words separated by hyphens. Each word must contain at least one letter. That is, the word must not be interpreted as a number. The names of packages are intended to be unique. ??? question "Are other project templates available?" Yes. For further information about project templates, command: ~~~text stack templates ~~~ From the root directory for all our Haskell projects, we command: ~~~text stack new helloworld new-template ~~~ For this first Stack command, Stack will do some setting up. For example, it will create the [Stack root](../topics/stack_root.md) directory. Other than any setting up, Stack will: * create the project directory; * download the project template; * attempt to populate the project template based on parameters; and * create and initialise Stack's project-level configuration file. Unless the parameters have been configured, Stack will note that parameters were needed by the template but not provided. That can be ignored for now. ??? question "How can I configure project template paramaters?" For further information, see the [`templates`](../configure/yaml/non-project.md#templates) non-project specific configuration option. As noted in Stack's output, parameters to populate project templates can also be set at the command line by using the options of the `stack new` command. ??? question "Can I create a new project in the current working directory?" Yes. Pass the `--bare` flag to cause Stack to create the project in the current working directory rather than in a new project directory. We now have a project in the `helloworld` directory! We will change to that directory, with command: ~~~text cd helloworld ~~~ ## The `stack build` command Next, we'll run the most important Stack command, [`stack build`](../commands/build_command.md). We command: ~~~text stack build ~~~ Stack needs a version of GHC and, on Windows, a version of MSYS2, in order to build your project. Stack will discover that you are missing it and will install it for you. You'll get intermediate download percentage statistics while the download is occurring. This command may take some time, depending on download speeds. ??? question "Where is the Stack-supplied GHC located?" You can use the [`stack path`](../commands/path_command.md) command for path information. To identify where GHC is installed, command: === "Unix-like" ~~~text stack exec -- which ghc /home//.stack/programs/x86_64-linux/ghc-9.6.5/bin/ghc ~~~ === "Windows" ~~~text stack exec -- where.exe ghc C:\Users\\AppData\Local\Programs\stack\x86_64-windows\ghc-9.6.5\bin\ghc.exe ~~~ As you can see from that path, the installation is placed to not interfere with any other GHC installation, whether system-wide or different GHC versions installed by Stack. ??? question "Can I use that version of GHC by commanding `ghc`?" No. GHC will be installed to the Stack programs directory, which is likely not on the PATH, so commanding `ghc` will not work. However, that version of GHC can be used in the Stack environment. For more information, see the [`stack exec`](../commands/exec_command.md) command, [`stack ghc`](../commands/ghc_command.md) command, and [`stack runghc`](../commands/ghc_command.md) command documentation. Once a version of GHC and, on Windows, a version of MSYS2, is installed, Stack will then build your project. The end of the output should look similar to this: === "Unix-like" ~~~text ... helloworld> configure (lib + exe) Configuring helloworld-0.1.0.0... helloworld> build (lib + exe) with ghc-9.8.4 Preprocessing library for helloworld-0.1.0.0..

Stack aims not to rebuild unnecessarily. If we command `stack build` a second time, nothing happens. ## The `stack exec` command The output of the previous command has three main steps. You can see, from the first two steps, that a library (lib) and an executable (exe) are being built and that the final step involved the installation of an executable named `helloworld-exe` (on Windows, the file is `helloworld-exe.exe`) (extract): ~~~text helloworld> configure (lib + exe) ... helloworld> build (lib + exe) with ghc-9.8.4 ... helloworld> copy/register ... Installing executable helloworld-exe in .../helloworld/.stack-work/.../bin ~~~ The executable is installed in a location in the project's `.stack-work` directory. Now, let's use the [`stack exec`](../commands/exec_command.md) command to run our executable. We command: ~~~text stack exec helloworld-exe ~~~ and the output is just: ~~~text someFunc ~~~ ??? question "Why is the output just `someFunc`?" The code in the `new-template` project template is very simple. The package has a Haskell module `Lib`: ~~~haskell module Lib ( someFunc ) where someFunc :: IO () someFunc = putStrLn "someFunc" ~~~ and a Haskell module `Main`: ~~~haskell module Main (main) where import Lib main :: IO () main = someFunc ~~~ `putStrLn "someFunc"` is an action that, when executed, outputs the string `someFunc` to the standard output channel. `stack exec` works by providing the same reproducible environment that was used to build your project to the command that you are running. Thus, it knew where to find `helloworld-exe` even though it is not on the PATH outside of that environment. ??? question "How I can find the PATH used in the Stack environment?" Command `stack path --bin-path` to see the PATH in the Stack environment. !!! info On Windows, the Stack environment includes the `\mingw64\bin`, `\usr\bin` and `\usr\local\bin` directories of the Stack-supplied MSYS2. If your executable depends on files (for example, dynamic-link libraries) in those directories and you want ro run it outside of the Stack environment, you will need to ensure copies of those files are on the PATH. ## The `stack test` command Finally, like all good software, `helloworld` actually has a test suite. Let's run it with the [`stack test`](../commands/test_command.md) command. We command: ~~~text stack test ~~~ The start of the output should look similar to this: === "Unix-like" ~~~text helloworld-0.1.0.0: unregistering (components added: test:helloworld-test) helloworld> configure (lib + exe + test) Configuring helloworld-0.1.0.0... helloworld> build (lib + exe + test) with ghc-9.8.4 Preprocessing library for helloworld-0.1.0.0..

# Getting started Stack is a program for developing [Haskell](https://www.haskell.org/) projects. This guide to getting started takes a new Stack user through the ways that Stack is typically used. It will not teach Haskell or involve much code, and it requires no prior experience of Stack or other Haskell tools. Terms used in the guide will be explained as they are introduced and are also defined in the [glossary](../glossary.md). Some of Stack's features will not be needed regularly or by all users. Other parts of Stack's documentation include its [commands](../commands/index.md) and its [configuration](../configure/index.md). ## Other Haskell tools First, simplifying greatly, lets briefly place Stack and other Haskell tools in the Haskell landscape. Haskell was specified in the [Haskell 98 Language and Library Reports](https://www.haskell.org/onlinereport/), first published in February 1999, and further specified in the [Haskell 2010 Language Report](https://www.haskell.org/onlinereport/haskell2010/), published in April 2010. Extensions to the language have been developed (see below). The Haskell compiler is **GHC** (the [Glasgow Haskell Compiler](https://www.haskell.org/ghc/)). It can compile Haskell code into executable and other binary files. GHC can also be used interactively (**GHCi**) and Stack supports such use. ~~~mermaid flowchart LR code@{ shape: docs, label: "Haskell code" } ghc[GHC] binaries@{ shape: docs, label: "Executable and other binary files" } code --> ghc --> binaries ~~~ Haskell code can be organised into *packages*. A Haskell package also includes a file that describes the package's contents. The most established description format is known as a [Cabal file](https://cabal.readthedocs.io/en/stable/file-format-changelog.html). The [**Hpack** project](https://github.com/sol/hpack) provides a modern alternative format (in a file named `package.yaml`) and a library and application that translates from that format to the legacy format. Stack has built-in support for Hpack. Other build tools (see below) do not. ~~~mermaid flowchart LR packageYaml@{ shape: doc, label: "package.yaml" } hpack[Hpack] cabalFile@{ shape: doc, label: "Cabal file" } packageYaml --> hpack --> cabalFile ~~~ The code in a Haskell package is organised into *components*, including components known as *libraries*. Historically, a package had no more than one library component. The Cabal specification has developed to allow a package to have named *sub-library* components as well as a main library. The code in a Haskell package can depend on the libraries in the same package or in another package. These are known as its *dependencies*. Two important public databases are **Hackage** [(the Haskell Package Repository)](https://hackage.haskell.org/) and [**Stackage**](https://hackage.haskell.org/). ~~~mermaid flowchart LR hackage@{ shape: lin-cyl, label: "Hackage (packages)" } stackage@{ shape: lin-cyl, label: "Stackage (snapshots)" } hackage --> stackage ~~~ Hackage is a database of Haskell packages, each identified by a name and version number. Stackage is a database of collections of Haskell package versions on Hackage that are known, by testing, to work well together and with a specific version of GHC. Those collections are known as *snapshots*. Stack can unpack packages from, and upload packages to, Hackage and builds making use of snapshots from Stackage. GHC comes with the libraries of certain Haskell packages (known as *boot packages*) already installed in its global database of installed libraries. These include the library of the [package `base`](https://hackage.haskell.org/package/base), which is a dependency of almost all other packages, and the library of [package `Cabal`](https://hackage.haskell.org/package/Cabal), which provides code to build packages and components of packages using GHC. GHC comes with an application [**Haddock**](https://haskell-haddock.readthedocs.io/latest/) that automatically generates web page and other documentation from annotated Haskell code. The Hackage and Stackage websites display that documentation. Stack supports the use of Haddock. ~~~mermaid flowchart LR code@{ shape: docs, label: "Haskell code" } haddock[Haddock] docs@{ shape: docs, label: "Documentation" } code --> haddock --> docs ~~~ **Hoogle** is a [website](https://hoogle.haskell.org/) and an [application](https://hackage.haskell.org/package/hoogle) that allows its users to search for the library components of Haskell packages, the modules they expose, and functions and types exported by modules. Stack supports the use of Hoogle on the command line. GHC is described in its [User Guide](https://downloads.haskell.org/ghc/latest/docs/users_guide/). It can be used directly but it is a complex application with many flags and options. These include flags to specify extensions to the Haskell language. Haskell *build tools* are applications that make it easier to use GHC, including by applying sensible defaults. Stack is such a build tool. Stack itself uses the Cabal library to build. ~~~mermaid flowchart LR stack[Stack] cabal["Cabal (the library)"] code@{ shape: docs, label: "Haskell code" } ghc[GHC] binaries@{ shape: docs, label: "Executable and other files" } subgraph buildtool ["Build tool"] direction TB stack --> cabal --> ghc end code --> buildtool --> binaries ~~~ When Haskell code changes, GHC and build tools aim to minimise what needs to be re-compiled. A Stack project may comprise only a single package, but Stack can also handle multi-package projects. Another build tool is **Cabal** (the tool) (named after the library). It is provided by the [`cabal-install`](https://hackage.haskell.org/package/cabal-install) Haskell package. Stack can be used independently of Cabal (the tool) but users can also use both, if they wish. Some popular code editors (including [Visual Studio Code](https://code.visualstudio.com/)) have extensions that support Haskell coding by providing an integrated development environment (IDE). Those extensions use **HLS** (the [Haskell Language Server](https://haskell-language-server.readthedocs.io/en/stable/)), an application that implements the Language Server Protocol for Haskell. Stack can manage versions of GHC and upgrade/downgrade Stack itself and is, in that sense, an *installer* of those applications as well as a build tool. However, Cabal (the tool) is not an installer and versions of HLS applicable to versions of GHC also need to be installed. [**GHCup**](https://www.haskell.org/ghcup/) is an installer of versions of GHC, HLS, Stack and Cabal (the tool) built for various operating systems and machine architectures. Stack can be configured to manage versions of GHC by using GHCup. ~~~mermaid flowchart TD ghcUp["GHCup installer"] ghc["GHC compiler"] hls["HLS IDE tool"] stack["Stack build tool, installer"] cabal["Cabal (the tool) build tool"] ghcUp -.-> ghc ghcUp -.-> hls ghcUp -.-> stack stack -- "(optional) to fetch GHC" --> ghcUp ghcUp -.-> cabal ~~~ ## Setting up The goal of setting up is a `stack` executable on the PATH. As we will see, when Stack is used, it sets other things up as needed. *[PATH]: An environment variable that specifies a list of directories searched for executable files. For further information about setting up, see the [documentation](../install_and_upgrade.md) on that topic. Return here when you know that Stack is on the PATH. This guide assumes that the directory where Stack install executables (the location reported by `stack path --local-bin`) has been added to the PATH. This guide assumes that your computer's operating system is one of Linux, macOS or Windows. Stack's commands are the same on all operating systems. stack-3.7.1/doc/tutorial/installed_package_databases.md0000644000000000000000000000763014734007300021414 0ustar0000000000000000
# 6. Installed package databases Time to take a short break from hands-on examples and discuss a little architecture. Stack has the concept of multiple *databases*. A database consists of a GHC package database (which contains the compiled version of a library), executables, and a few other things as well. To give you an idea, the contents of the parent directory of the `stack path --local-pkg-db` directory are the directories: ~~~text bin doc lib pkgdb ~~~ Databases in Stack are *layered*. For example, the database listing we just gave is called a *local* database (also known as a *mutable* database). That is layered on top of a *snapshot* database (also known as a *write-only* database). The snapshot database contains the libraries and executables that are considered to be *immutable*. Finally, GHC itself ships with a number of libraries and executables, also considered to be immutable, which forms the *global* database. To get a quick idea of this, we can look at the output of the `stack exec -- ghc-pkg list` command in our `helloworld` project: ~~~text Cabal-3.6.3.0 Win32-2.12.0.1 array-0.5.4.0 base-4.16.2.0 binary-0.8.9.0 bytestring-0.11.3.1 containers-0.6.5.1 deepseq-1.4.6.1 directory-1.3.6.2 exceptions-0.10.4 filepath-1.4.2.2 (ghc-9.2.3) ghc-bignum-1.2 ghc-boot-9.2.3 ghc-boot-th-9.2.3 ghc-compact-0.1.0.0 ghc-heap-9.2.3 ghc-prim-0.8.0 ghci-9.2.3 haskeline-0.8.2 hpc-0.6.1.0 integer-gmp-1.1 libiserv-9.2.3 mtl-2.2.2 parsec-3.1.15.0 pretty-1.1.3.6 process-1.6.13.2 rts-1.0.2 stm-2.5.0.2 template-haskell-2.18.0.0 text-1.2.5.0 time-1.11.1.1 transformers-0.5.6.2 xhtml-3000.2.2.1 acme-missiles-0.3 helloworld-0.1.0.0 ~~~ where `` refers to the directory output by the command `stack path --global-pkg-db`, and so on. Notice that `acme-missiles` ends up in the *snapshot* database. Any package which comes from Hackage, an archive, or a repository is considered to be an *immutable* package. Anything which is considered *mutable*, or depends on something mutable, ends up in the *local* database. This includes your own code and any other packages located on a local file path. The reason we have this structure is that: * it lets multiple projects reuse the same binary builds of immutable packages, * but doesn't allow different projects to "contaminate" each other by putting non-standard content into the shared snapshot database. As you probably guessed, there can be multiple snapshot databases available. See the contents of the `snapshots` directory in the [Stack root](../topics/stack_root.md). * On Unix-like operating systems, each snapshot is in the last of a sequence of three subdirectories named after the platform, a 256-bit hash of the source map (how the package should be built -- including the compiler, options, and immutable dependencies), and the GHC version. * On Windows, each snapshot is in a subdirectory that is a shorter hash (eight characters) of the sequence of three directories used on Unix-like operating systems. This is done to avoid problems created by default limits on file path lengths on Windows systems. These snapshot databases don't get layered on top of each other; they are each used separately. In reality, you'll rarely — if ever — interact directly with these databases, but it's good to have a basic understanding of how they work so you can understand why rebuilding may occur at different points. stack-3.7.1/doc/tutorial/locations_used_by_stack.md0000644000000000000000000000743614734007300020651 0ustar0000000000000000
# 11. Locations used by Stack Generally, you don't need to worry about where Stack stores various files. But some people like to know this stuff. That's when the `stack path` command is useful. ## The `stack path` command `stack path --help` explains the available options and, consequently, the output of the command: ~~~text --stack-root Global Stack root directory --global-config Global Stack configuration file --project-root Project root (derived from stack.yaml file) --config-location Configuration location (where the stack.yaml file is) --bin-path PATH environment variable --programs Install location for GHC and other core tools (see 'stack ls tools' command) --compiler-exe Compiler binary (e.g. ghc) --compiler-bin Directory containing the compiler binary (e.g. ghc) --compiler-tools-bin Directory containing binaries specific to a particular compiler --local-bin Directory where Stack installs executables (e.g. ~/.local/bin (Unix-like OSs) or %APPDATA%\local\bin (Windows)) --extra-include-dirs Extra include directories --extra-library-dirs Extra library directories --snapshot-pkg-db Snapshot package database --local-pkg-db Local project package database --global-pkg-db Global package database --ghc-package-path GHC_PACKAGE_PATH environment variable --snapshot-install-root Snapshot installation root --local-install-root Local project installation root --snapshot-doc-root Snapshot documentation root --local-doc-root Local project documentation root --local-hoogle-root Local project documentation root --dist-dir Dist work directory, relative to package directory --local-hpc-root Where HPC reports and tix files are stored ~~~ In addition, `stack path` accepts the flags above on the command line to state which keys you're interested in. This can be convenient for scripting. As a simple example, let's find out the sandboxed versions of GHC that Stack installed: === "Unix-like" Command: ~~~text ls $(stack path --programs)/*.installed /home//.stack/programs/x86_64-linux/ghc-9.0.2.installed ~~~ === "Windows" In PowerShell, command: ~~~text dir "$(stack path --programs)/*.installed" Directory: C:\Users\mikep\AppData\Local\Programs\stack\x86_64-windows Mode LastWriteTime Length Name ---- ------------- ------ ---- -a--- 27/07/2022 5:40 PM 9 ghc-9.0.2.installed -a--- 25/02/2022 11:39 PM 9 msys2-20210604.installed ~~~ While we're talking about paths, to wipe our Stack install completely, here's what typically needs to be removed: 1. the Stack root folder (see `stack path --stack-root`, before you uninstall); 2. if different, the folder containing Stack's global configuration file (see `stack path --global-config`, before you uninstall); 3. on Windows, the folder containing Stack's tools (see `stack path --programs`, before you uninstall), which is located outside of the Stack root folder; and 4. the `stack` executable file (see `which stack`, on Unix-like operating systems, or `where.exe stack`, on Windows). You may also want to delete `.stack-work` folders in any Haskell projects that you have built using Stack. The `stack uninstall` command provides information about how to uninstall Stack. stack-3.7.1/doc/tutorial/multi-package_projects.md0000644000000000000000000000572014734007355020417 0ustar0000000000000000
# 9. Multi-package projects Until now, everything we have done with Stack has used a single-package project. However, Stack's power truly shines when you're working on multi-package projects. All the functionality you'd expect to work just does: dependencies between packages are detected and respected, dependencies of all packages are just as one cohesive whole, and if anything fails to build, the build commands exits appropriately. Let us demonstrate this with the `wai-app-static` and `yackage` packages, starting in the root directory for all our Haskell projects. Command: ~~~text mkdir multi cd multi stack unpack wai-app-static yackage ~~~ The last command should report something like: ~~~text ... Unpacked wai-app-static (from Hackage) to .../multi/wai-app-static-3.1.9/. Unpacked yackage (from Hackage) to .../multi/yackage-0.8.1/. ~~~ Then command: ~~~text stack init ~~~ The command should report something like: ~~~text Looking for Cabal or package.yaml files to use to initialise Stack's project-level configuration file. Using the Cabal packages: * wai-app-static-3.1.9/ * yackage-0.8.1/ Cabal file warning in .../multi/yackage-0.8.1/yackage.cabal@47:40: version operators used. To use version operators the package needs to specify at least 'cabal-version: >= 1.8'. Cabal file warning in .../multi/yackage-0.8.1/yackage.cabal@21:36: version operators used. To use version operators the package needs to specify at least 'cabal-version: >= 1.8'. Selecting the best among 12 snapshots... Note: Matches ... Selected the snapshot ... Initialising Stack's project-level configuration file using snapshot ... Considered 2 user packages. Writing configuration to stack.yaml. Stack's project-level configuration file has been initialised. ~~~ Then command: ~~~text stack build --haddock --test ~~~ Stack should build and test the project packages. If you look at the `stack.yaml` file, you'll see exactly what you'd expect: ~~~yaml snapshot: url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/22/31.yaml packages: - wai-app-static-3.1.9 - yackage-0.8.1 ~~~ Notice that multiple directories are listed in the `packages` key. In addition to local directories, you can also refer to packages available in a Git repository or in a tarball over HTTP/HTTPS. This can be useful for using a modified version of a dependency that hasn't yet been released upstream. !!! note When adding upstream packages directly to your project it is important to distinguish _project packages_ located locally from the upstream _dependency packages_. Otherwise you may have trouble running `stack ghci`. See [stack.yaml documentation](../configure/yaml/project.md#packages) for more details. stack-3.7.1/doc/tutorial/package_description.md0000644000000000000000000003455414774240637017776 0ustar0000000000000000
# 2. Package description Let us begin to look at the `helloworld` example in more detail to understand better how Stack works. The contents of the project directory are set out below. Click :material-plus-circle: to learn more about each file or directory: ~~~shell . ├── .stack-work # (1)! │   └── ... │ ├── app │   └── Main.hs # (2)! ├── src │   └── Lib.hs # (3)! ├── test │ └── Spec.hs # (4)! │ ├── .gitignore # (5)! ├── CHANGELOG.md # (6)! ├── LICENSE # (7)! ├── README.md # (8)! │ ├── package.yaml # (9)! ├── helloworld.cabal # (10)! ├── Setup.hs # (11)! │ └── stack.yaml # (12)! ~~~ 1. The Stack work directory for the project and the project package. Stack work directories are ones in which Stack stores files created during the build process. A product of the build - does not affect the build (other than to avoid rebuilding things unnecessarily). 2. The Haskell source code for the executable (application). As your project develops you can add further source code files to the `app` directory. 3. The executable uses a library. The Haskell source code for the library. As your project develops you can add further source code files to the `src` directory. 4. The package has a test suite executable. The Haskell source code for the test suite. As your project develops you can add further source code files to the `test` directory. 5. A text file used to configure the Git tool to ignore certain files. Does not affect the build. 6. A text file in the Markdown format in which changes to the project can be documented. Does not affect the build. 7. A text file used to document the copyright applicable to the project's files and the licence for the use of those files. Does not affect the build. 8. A text file in the Markdown format which is intended to be read by users of the project. Does not affect the build. 9. A file describing the package in the Hpack format. See further below. 10. A file describing the package in the Cabal format. See further below. 11. A Haskell source file which is a component of the Cabal build system. See further below. 12. A text file in the YAML format, containing Stack's project-level configuration. See the next part of this guide to getting started. The files of most interest here are `package.yaml` and `helloworld.cabal`. We will also explain the `Setup.hs` file. ## Package description formats Each package contains a file that describes the package. It is located in the package's root directory. ??? question "What is covered by a package description?" A package description includes information such as the package name and version, and the package's *components*. A package can have an optional main library component and optional named sub-library components. It can also have optional executable components, test suite components and benchmark components. The description identifies other packages on which those components depend. Stack is aware of two different formats of package description, and both files may be present in the package's root directory:
- :material-package-variant:{ .lg .middle } __Cabal: A Cabal file__ Used directly by the Cabal build system. Unique but simple syntax. Named after the package (eg `helloworld.cabal`). If no `package.yaml` file, used directly by Stack. --- Specified by the Cabal project: [:octicons-arrow-right-24: Learn more](https://cabal.readthedocs.io/en/stable/cabal-package-description-file.html) - :material-package-variant-plus:{ .lg .middle } __Hpack: a package.yaml file__ Used by Stack to create a Cabal file. YAML syntax. Named `package.yaml`. Stack's preferred format. If present, used by Stack. --- Specified by the Hpack project: [:octicons-arrow-right-24: Learn more](https://github.com/sol/hpack?tab=readme-ov-file#documentation)
??? question "Why use the Hpack format?" A `package.yaml` file can be more concise and less repetitive than the Cabal file that is generated from it. That is because the Hpack format uses defaults and top-level keys common to other parts of the format. The YAML syntax, which may already be familiar for some users, can also avoid repetition. In particular, the format's defaults can infer the names of exposed and other modules. The format allows a user to specify defaults in a file on GitHub or a local file. ??? question "I use the Hpack format. Should I also check-in a Cabal file to my repository?" Yes. This helps people who do not use Stack or the Hpack tool separately. ## `package.yaml` The `package.yaml` file describes the package in the [Hpack format](https://github.com/sol/hpack?tab=readme-ov-file#documentation). If a `package.yaml` file is present, Stack will use its built-in Hpack functionality to create a Cabal file. ??? question "What are the contents of the `package.yaml` file?" The contents of the `package.yaml` file for the `helloworld` example are described below, using additional YAML comments: ~~~yaml # The name of the package: name: helloworld # The version of the package: version: 0.1.0.0 # The GitHub repository for the package (optional): github: "githubuser/helloworld" # The licence for the use of the package's files (optional): license: BSD-3-Clause # The author of the package (optional): author: "Author name here" # The email address to contact the maintainer of the package (optional): maintainer: "example@example.com" # The copyright for the package's files (optional): copyright: "2025 Author name here" # Extra files (if any) to be distributed with the source files of the # package: extra-source-files: - README.md - CHANGELOG.md # Metadata used when publishing your package # synopsis: Short description of your package # category: Web # To avoid duplicated efforts in documentation and dealing with the # complications of embedding Haddock markup inside cabal files, it is # common to point users to the README.md file. description: Please see the README on GitHub at # Dependencies applicable to all components: dependencies: - base >= 4.7 && < 5 # GHC options (if any) common to all components: ghc-options: # These GHC flags affect which warnings GHC will emit: - -Wall - -Wcompat - -Widentities - -Wincomplete-record-updates - -Wincomplete-uni-patterns - -Wmissing-export-lists - -Wmissing-home-modules - -Wpartial-fields - -Wredundant-constraints # The main (unnamed) library component of the package (if it has one): library: # Directories containing source files: source-dirs: src # The executable components of the package (if it has any): executables: # The executable component named 'helloworld-exe': helloworld-exe: # The source file exporting the 'main' function: main: Main.hs # Directories containing source files: source-dirs: app # GHC options applicable to the component: ghc-options: # Link the program with the 'threaded' version of GHC's runtime system: - -threaded # Make all of GHC's runtime system (RTS) options available: - -rtsopts # Compile so as to use simultaneous threads when running the program, # based on how many processors are in the machine. - -with-rtsopts=-N # Dependencies applicable to the component: dependencies: # The main library of the package: - helloworld # The test suite components of the package (if it has any).

For a package `my-package-0.1.0.0` with a main library, an executable named `my-program`, and a dependency only on the `base` package, its `package.yaml` file could be as simple as the one below: ~~~yaml package: my-package version: 0.1.0.0 dependencies: - base library: source-dirs: src executables: my-program: main: Main.hs source-dirs: app ghc-options: - -threaded - -rtsopts - -with-rtsopts=-N dependencies: - my-package ~~~ ## `helloworld.cabal` In the case of the `helloworld` example, the `helloworld.cabal` file is updated automatically as part of the `stack build` process and should not be modified. If the `package.yaml` file were deleted, Stack would use the Cabal file directly. ??? question "What are the contents of the `helloworld.cabal` file?" The contents of the `helloworld.cabal` file are described below, using additional Cabal file comments: ~~~text -- The version of the Cabal package description format specification: cabal-version: 2.2 -- This file has been generated from package.yaml by hpack version 0.37.0. -- -- see: https://github.com/sol/hpack -- The name of the package: name: helloworld -- The version of the package: version: 0.1.0.0 -- The description of the package: description: Please see the README on GitHub at -- A URL for the package: homepage: https://github.com/githubuser/helloworld#readme -- A URL for bug reports for the package: bug-reports: https://github.com/githubuser/helloworld/issues -- The author of the package: author: Author name here -- The email address to contact the maintainer of the package: maintainer: example@example.com -- The copyright for the package's files: copyright: 2025 Author name here -- The licence for the use of the package's files: license: BSD-3-Clause -- The file documenting the terms of the licence: license-file: LICENSE -- The Cabal system build type of the package: build-type: Simple -- Extra files to be distributed with the source files of the package: extra-source-files: README.md CHANGELOG.md -- The respository for the package: source-repository head type: git location: https://github.com/githubuser/helloworld -- The main (unnamed) library component of the package: library -- The modules that the library exposes: exposed-modules: Lib -- The other modules of the compoment: other-modules: Paths_helloworld -- Automatically generated modules of the component: autogen-modules: Paths_helloworld -- Directories containing source files: hs-source-dirs: src -- GHC options applicable to the component.

Technically, it is not needed by Stack, but it is considered good practice to include it. The file we're using is boilerplate: ~~~haskell import Distribution.Simple main = defaultMain ~~~ stack-3.7.1/doc/tutorial/project_configuration.md0000644000000000000000000000443315023557531020356 0ustar0000000000000000
# 3. Project configuration Let us continue to look at the `helloworld` example in more detail to understand better how Stack works. As discussed in the previous part of this guide to getting started, some of the contents of the project directory are set out below. The item of interest here is the `stack.yaml` file. ~~~text . ├── .stack-work │   └── ... ... │ ├── package.yaml ├── helloworld.cabal ├── Setup.hs │ └── stack.yaml ~~~ ## `stack.yaml` Stack requires a Stack project-level configuration file for every project. `stack.yaml` is that file. The contents of the file set project-specific and non-project-specific options that apply to the project. (Non-project specific options that affect the project may also be set in a [global Stack configuration file](../configure/yaml/index.md#project-level-and-global-configuration-files).) The contents of the `stack.yaml` file include comments beginning `#`. Ignoring those comments, the contents will look something like this: ~~~yaml snapshot: url: https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/23/24.yaml packages: - . ~~~ The key [`snapshot`](../configure/yaml/project.md#snapshot) is a project-specific configuration option. Its value tells Stack *how* to build your package: which GHC version to use, which versions of package dependencies to use, and so on. Our value here says to use [LTS Haskell 23.24](https://www.stackage.org/lts-23.24), which implies GHC 9.8.4 (which is why `stack build` installs that version of GHC if it is not already available to Stack). There are a number of values you can use for `snapshot`, which we'll cover later. The key [`packages`](../configure/yaml/project.md#packages) is another project-specific configuration option. Its value tells Stack which project packages, located locally, to build. In our simple example, we have only a single project package, located in the same directory, so '`.`' suffices. However, Stack has powerful support for multi-package projects, which we'll describe as this guide progresses. stack-3.7.1/doc/tutorial/stack_build_synonyms.md0000644000000000000000000000732114734007300020213 0ustar0000000000000000
# 7. `stack build` synonyms Let's look at a subset of the `stack --help` output: ~~~text build Build the package(s) in this directory/configuration install Shortcut for 'build --copy-bins' test Shortcut for 'build --test' bench Shortcut for 'build --bench' haddock Shortcut for 'build --haddock' ~~~ Four of these commands are just synonyms for the `build` command. They are provided for convenience for common cases (e.g., `stack test` instead of `stack build --test`) and so that commonly expected commands just work. What's so special about these commands being synonyms? It allows us to make much more composable command lines. For example, we can have a command that builds executables, generates Haddock documentation (Haskell API-level docs), and builds and runs your test suites, with: ~~~text stack build --haddock --test ~~~ You can even get more inventive as you learn about other flags. For example, take the following command: ~~~text stack build --pedantic --haddock --test --exec "echo Yay, it succeeded" --file-watch ~~~ This command will: * turn on all warnings and errors (the `--pedantic` flag) * build your library and executables * generate Haddocks (the `--haddock` flag) * build and run your test suite (the `--test` flag) * run the command `echo Yay, it succeeded` when that completes (the `--exec` option) * after building, watch for changes in the files used to build the project, and kick off a new build when done (the `--file-watch` flag) ## The `stack install` command and `copy-bins` option It's worth calling out the behavior of the `install` command and `--copy-bins` option, since this has confused a number of users (especially when compared to behavior of other tools like Cabal (the tool)). The `install` command does precisely one thing in addition to the build command: it copies any generated executables to the local binary directory. You may recognize the default value for that path: On Unix-like operating systems, command: ~~~text stack path --local-bin /home//.local/bin ~~~ On Windows, command: ~~~text stack path --local-bin C:\Users\\AppData\Roaming\local\bin ~~~ That's why the download page recommends adding that directory to your PATH. This feature is convenient, because now you can simply run `executable-name` in your shell instead of having to run `stack exec executable-name` from inside your project directory. Since it's such a point of confusion, let me list a number of things Stack does *not* do specially for the `install` command: * Stack will always build any necessary dependencies for your code. The install command is not necessary to trigger this behavior. If you just want to build a project, run `stack build`. * Stack will *not* track which files it's copied to your local binary directory nor provide a way to automatically delete them. There are many great tools out there for managing installation of binaries, and Stack does not attempt to replace those. * Stack will not necessarily be creating a relocatable executable. If your executables hard-codes paths, copying the executable will not change those hard-coded paths. * At the time of writing, there's no way to change those kinds of paths with Stack, but see [issue #848 about --prefix](https://github.com/commercialhaskell/stack/issues/848) for future plans. That's really all there is to the `install` command: for the simplicity of what it does, it occupies a much larger mental space than is warranted. stack-3.7.1/doc/tutorial/stack_build_targets.md0000644000000000000000000001223114734007300017761 0ustar0000000000000000
# 8. `stack build` targets We haven't discussed this too much yet, but, in addition to having a number of synonyms *and* taking a number of options on the command line, the `build` command *also* takes many arguments. These are parsed in different ways, and can be used to achieve a high level of flexibility in telling Stack exactly what you want to build. We're not going to cover the full generality of these arguments here; instead, there's documentation covering the full [build command syntax](../commands/build_command.md). Here, we'll just point out a few different types of arguments: * You can specify a *package name*, e.g. `stack build vector`. * This will attempt to build the `vector` package, whether it's a local package, in your extra-deps, in your snapshot, or just available upstream. If it's just available upstream but not included in your locals, extra-deps, or snapshot, the newest version is automatically promoted to an extra-dep. * You can also give a *package identifier*, which is a package name plus version, e.g. `stack build yesod-bin-1.4.14`. * This is almost identical to specifying a package name, except it will (1) choose the given version instead of latest, and (2) error out if the given version conflicts with the version of a project package. * The most flexibility comes from specifying individual *components*, e.g. `stack build helloworld:test:helloworld-test` says "build the test suite component named helloworld-test from the helloworld package." * In addition to this long form, you can also shorten it by skipping what type of component it is, e.g. `stack build helloworld:helloworld-test`, or even skip the package name entirely, e.g. `stack build :helloworld-test`. * Finally, you can specify individual *directories* to build to trigger building of any project packages included in those directories or subdirectories. When you give no specific arguments on the command line (e.g., `stack build`), it's the same as specifying the names of all of your project packages. If you just want to build the package for the directory you're currently in, you can use `stack build .`. ## Components, --test, and --bench Here's one final important yet subtle point. Consider our `helloworld` package: it has a library component, an executable `helloworld-exe`, and a test suite `helloworld-test`. When you run `stack build helloworld`, how does it know which ones to build? By default, it will build the library (if any) and all of the executables but ignore the test suites and benchmarks. This is where the `--test` and `--bench` flags come into play. If you use them, those components will also be included. So `stack build --test helloworld` will end up including the helloworld-test component as well. You can bypass this implicit adding of components by being much more explicit, and stating the components directly. For example, the following will not build the `helloworld-exe` executable: ~~~text stack purge stack build :helloworld-test helloworld> configure (lib + test) Configuring helloworld-0.1.0.0... helloworld> build (lib + test) with ghc-9.6.5 Preprocessing library for helloworld-0.1.0.0.. Building library for helloworld-0.1.0.0.. [1 of 2] Compiling Lib [2 of 2] Compiling Paths_helloworld Preprocessing test suite 'helloworld-test' for helloworld-0.1.0.0.. Building test suite 'helloworld-test' for helloworld-0.1.0.0.. [1 of 2] Compiling Main [2 of 2] Compiling Paths_helloworld [3 of 3] Linking .stack-work\dist\\build\helloworld-test\helloworld-test.exe helloworld> copy/register Installing library in ...\helloworld\.stack-work\install\... Registering library for helloworld-0.1.0.0.. helloworld> test (suite: helloworld-test) Test suite not yet implemented helloworld> Test suite helloworld-test passed Completed 2 action(s). ~~~ We first purged our project to clear old results so we know exactly what Stack is trying to do. The last line shows that our command also *runs* the test suite it just built. This may surprise some people who would expect tests to only be run when using `stack test`, but this design decision is what allows the `stack build` command to be as composable as it is (as described previously). The same rule applies to benchmarks. To spell it out completely: * The `--test` and `--bench` flags simply state which components of a package should be built, if no explicit set of components is given * The default behavior for any test suite or benchmark component which has been built is to also run it You can use the `--no-run-tests` and `--no-run-benchmarks` flags to disable running of these components. You can also use `--no-rerun-tests` to prevent running a test suite which has already passed and has not changed. !!! note Stack doesn't build or run test suites and benchmarks for non-local packages. This is done so that a command like `stack test` doesn't need to run 200 test suites! stack-3.7.1/doc/tutorial/stack_configuration.md0000644000000000000000000000575314734007300020013 0ustar0000000000000000
# 14. Stack configuration Whenever you run something with Stack, it needs a project-level configuration file. The algorithm Stack uses to find such a file is: 1. Check for a `--stack-yaml` option on the command line 2. Check for a `STACK_YAML` environment variable 3. Check the current directory and all ancestor directories for a `stack.yaml` file The first two provide a convenient method for using an alternate configuration. For example: `stack build --stack-yaml stack-ghc-9.2.3.yaml` can be used by your CI system to check your code against GHC 9.2.3. Setting the `STACK_YAML` environment variable can be convenient if you're going to be running commands like `stack ghc` in other directories, but you want to use the configuration you defined in a specific project. If Stack does not find a project level configuration file in any of the three specified locations, the *implicit global* logic kicks in. You've probably noticed that phrase a few times in the output from commands above. Implicit global is essentially a hack to allow Stack to be useful in a non-project setting. When no implicit global configuration file exists, Stack creates one for you with the latest LTS snapshot. This allows you to do things like: * compile individual files easily with `stack ghc` * build executables without starting a project, e.g. `stack install pandoc` Keep in mind that there's nothing magical about this implicit global configuration. It has no effect on projects at all. Every package you install with it is put into isolated databases just like everywhere else. The only magic is that it's the catch-all project whenever you're running Stack somewhere else. ## Package description vs project-level configuration Now that we've covered a lot of ways to use Stack, this quick summary of package description files versus Stack's project-level configuration file will hopefully make sense and be a good reminder for future uses of Stack:
- __Package description__ Each package has a package description file in the Cabal format (a Cabal file named after the package. A package may have a package description file in the Hpack format (`package.yaml`). If one exists, Stack will use it to generate the Cabal file. --- Specifies which other Haskell packages are dependencies of the package. --- Specifies the components, modules, and Cabal flags provided by the package. - __Project-level configuration__ Each project has a project-level configuration file (named `stack.yaml`, by default). A project can have one or more project packages. --- Specifies which package versions are available to be used. --- Can override the Cabal flag settings for individual packages.

# 15. In conclusion Stack is not the only tool available for building Haskell code. If you are happy building Haskell code with other tools, you may not need Stack. If you're experiencing problems with other tools, give Stack a try. If you're a new user who has no experience with other tools, we recommend Stack. It aims to be easy to use and its defaults match modern best practices in Haskell development. Other key features of Stack include:
- __Sandboxing__ A 'sandbox' is a development environment that is isolated from other parts of the system. The concept of sandboxing is built in to Stack. - __Snapshots__ --- A snapshot specifies a GHC versions and a set of package versions that work well together. Stack uses snapshots to define precisely the set of package versions available for a project. - __Reproducibility__ --- Stack goes to great lengths to ensure that `stack build` today does the same thing tomorrow. Changing the build plan is always an explicit decision. - __Building dependencies__ --- Stack automatically builds dependencies.

# 13. Using GHC interactively GHCi is the interactive GHC environment, a.k.a. the REPL. You *could* access it with command: ~~~text stack exec ghci ~~~ But that won't load up locally written modules for access. For that, use the `stack ghci` or `stack repl` commands, which are equivalent. ## The `stack ghci` or `stack repl` command To then load modules from your project in GHCi, use the `:module` command (`:m` for short) followed by the module name. !!! note If you have added packages to your project please make sure to mark them as extra-deps for faster and reliable usage of `stack ghci`. Otherwise GHCi may have trouble due to conflicts of compilation flags or having to unnecessarily interpret too many modules. See Stack's project-level [configuration](../configure/yaml/project.md#extra-deps) to learn how to configure a package as an extra-dep. For further information, see the [REPL environment](../commands/ghci_command.md) documentation. stack-3.7.1/src/setup-shim/StackSetupShim.hs0000644000000000000000000001442214734007356017161 0ustar0000000000000000{-# LANGUAGE CPP #-} {-# LANGUAGE PackageImports #-} module StackSetupShim where -- Stack no longer supports Cabal < 2.2 and, consequently, GHC versions before -- GHC 8.4 or base < 4.11.0.0.

This package contains: . * the monad transformer class (in "Control.Monad.Trans.Class") and IO monad class (in "Control.Monad.IO.Class") . * concrete functor and monad transformers, each with associated operations and functions to lift operations associated with other transformers. . The package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see "Control.Monad.Trans.Class" for some examples). Alternatively, it can be used with the non-portable monad classes in the @mtl@ or @monads-tf@ packages, which automatically lift operations introduced by monad transformers through other transformers. category: Control author: Andy Gill, Ross Paterson exposed: True exposed-modules: Control.Applicative.Backwards Control.Applicative.Lift Control.Monad.IO.Class Control.Monad.Signatures Control.Monad.Trans.Class Control.Monad.Trans.Cont Control.Monad.Trans.Except Control.Monad.Trans.Error Control.Monad.Trans.Identity Control.Monad.Trans.List Control.Monad.Trans.Maybe Control.Monad.Trans.Reader Control.Monad.Trans.RWS Control.Monad.Trans.RWS.Lazy Control.Monad.Trans.RWS.Strict Control.Monad.Trans.State Control.Monad.Trans.State.Lazy Control.Monad.Trans.State.Strict Control.Monad.Trans.Writer Control.Monad.Trans.Writer.Lazy Control.Monad.Trans.Writer.Strict Data.Functor.Classes Data.Functor.Compose Data.Functor.Constant Data.Functor.Product Data.Functor.Reverse Data.Functor.Sum trusted: False import-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/trans_ALYlebOVzVI4kxbFX5SGhm library-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/trans_ALYlebOVzVI4kxbFX5SGhm data-dir: /opt/ghc/7.10.1/share/x86_64-linux-ghc-7.10.1/transformers-0.4.2.0 hs-libraries: HStransformers-0.4.2.0-ALYlebOVzVI4kxbFX5SGhm depends: base-4.8.0.0-1b689eb8d72c4d4cc88f445839c1f01a haddock-interfaces: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/transformers-0.4.2.0/transformers.haddock haddock-html: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/transformers-0.4.2.0 pkgroot: "/opt/ghc/7.10.1/lib/ghc-7.10.1" --- name: hoopl version: 3.10.0.2 id: hoopl-3.10.0.2-8c8dfc4c3140e5f7c982da224c3cb1f0 key: hoopl_JxODiSRz1e84NbH6nnZuUk license: BSD3 maintainer: nr@cs.tufts.edu homepage: http://ghc.cs.tufts.edu/hoopl/ synopsis: A library to support dataflow analysis and optimization description: Higher-order optimization library .

The 'ByteString' type represents sequences of bytes or 8-bit characters. It is suitable for high performance use, both in terms of large data quantities, or high speed requirements. The 'ByteString' functions follow the same style as Haskell\'s ordinary lists, so it is easy to convert code from using 'String' to 'ByteString'. . Two 'ByteString' variants are provided: . * Strict 'ByteString's keep the string as a single large array. This makes them convenient for passing data between C and Haskell. . * Lazy 'ByteString's use a lazy list of strict chunks which makes it suitable for I\/O streaming tasks. . The @Char8@ modules provide a character-based view of the same underlying 'ByteString' types. This makes it convenient to handle mixed binary and 8-bit character content (which is common in many file formats and network protocols). . The 'Builder' module provides an efficient way to build up 'ByteString's in an ad-hoc way by repeated concatenation. This is ideal for fast serialisation or pretty printing. . There is also a 'ShortByteString' type which has a lower memory overhead and can be converted to or from a 'ByteString', but supports very few other operations. It is suitable for keeping many short strings in memory. . 'ByteString's are not designed for Unicode. For Unicode strings you should use the 'Text' type from the @text@ package. . These modules are intended to be imported qualified, to avoid name clashes with "Prelude" functions, e.g. . > import qualified Data.ByteString as BS category: Data author: Don Stewart, Duncan Coutts exposed: True exposed-modules: Data.ByteString Data.ByteString.Char8 Data.ByteString.Unsafe Data.ByteString.Internal Data.ByteString.Lazy Data.ByteString.Lazy.Char8 Data.ByteString.Lazy.Internal Data.ByteString.Short Data.ByteString.Short.Internal Data.ByteString.Builder Data.ByteString.Builder.Extra Data.ByteString.Builder.Prim Data.ByteString.Builder.Internal Data.ByteString.Builder.Prim.Internal Data.ByteString.Lazy.Builder Data.ByteString.Lazy.Builder.Extras Data.ByteString.Lazy.Builder.ASCII hidden-modules: Data.ByteString.Builder.ASCII Data.ByteString.Builder.Prim.Binary Data.ByteString.Builder.Prim.ASCII Data.ByteString.Builder.Prim.Internal.Floating Data.ByteString.Builder.Prim.Internal.UncheckedShifts Data.ByteString.Builder.Prim.Internal.Base16 trusted: False import-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/bytes_6vj5EoliHgNHISHCVCb069 library-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/bytes_6vj5EoliHgNHISHCVCb069 data-dir: /opt/ghc/7.10.1/share/x86_64-linux-ghc-7.10.1/bytestring-0.10.6.0 hs-libraries: HSbytestring-0.10.6.0-6vj5EoliHgNHISHCVCb069 include-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/bytes_6vj5EoliHgNHISHCVCb069/include includes: fpstring.h depends: base-4.8.0.0-1b689eb8d72c4d4cc88f445839c1f01a deepseq-1.4.1.1-c1376f846fa170f2cc2cb2e57b203339 ghc-prim-0.4.0.0-7c945cc0c41d3b7b70f3edd125671166 integer-gmp-1.0.0.0-3c947e5fb6dca14804d9b2793c521b67 haddock-interfaces: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/bytestring-0.10.6.0/bytestring.haddock haddock-html: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/bytestring-0.10.6.0 pkgroot: "/opt/ghc/7.10.1/lib/ghc-7.10.1" --- name: deepseq version: 1.4.1.1 id: deepseq-1.4.1.1-c1376f846fa170f2cc2cb2e57b203339 key: deeps_FpR4obOZALU1lutWnrBldi license: BSD3 maintainer: libraries@haskell.org synopsis: Deep evaluation of data structures description: This package provides methods for fully evaluating data structures (\"deep evaluation\").

It is implemented on top of an 'NFData' typeclass (\"Normal Form Data\", data structures with no unevaluated components) which defines strategies for fully evaluating different data types. category: Control exposed: True exposed-modules: Control.DeepSeq trusted: False import-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/deeps_FpR4obOZALU1lutWnrBldi library-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/deeps_FpR4obOZALU1lutWnrBldi data-dir: /opt/ghc/7.10.1/share/x86_64-linux-ghc-7.10.1/deepseq-1.4.1.1 hs-libraries: HSdeepseq-1.4.1.1-FpR4obOZALU1lutWnrBldi depends: array-0.5.1.0-e29cdbe82692341ebb7ce6e2798294f9 base-4.8.0.0-1b689eb8d72c4d4cc88f445839c1f01a haddock-interfaces: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/deepseq-1.4.1.1/deepseq.haddock haddock-html: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/deepseq-1.4.1.1 pkgroot: "/opt/ghc/7.10.1/lib/ghc-7.10.1" --- name: array version: 0.5.1.0 id: array-0.5.1.0-e29cdbe82692341ebb7ce6e2798294f9 key: array_FaHmcBFfuRM8kmZLEY8D5S license: BSD3 maintainer: libraries@haskell.org synopsis: Mutable and immutable arrays description: In addition to providing the "Data.Array" module , this package also defines the classes 'IArray' of immutable arrays and 'MArray' of arrays mutable within appropriate monads, as well as some instances of these classes. category: Data Structures exposed: True exposed-modules: Data.Array Data.Array.Base Data.Array.IArray Data.Array.IO Data.Array.IO.Safe Data.Array.IO.Internals Data.Array.MArray Data.Array.MArray.Safe Data.Array.ST Data.Array.ST.Safe Data.Array.Storable Data.Array.Storable.Safe Data.Array.Storable.Internals Data.Array.Unboxed Data.Array.Unsafe trusted: False import-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/array_FaHmcBFfuRM8kmZLEY8D5S library-dirs: /opt/ghc/7.10.1/lib/ghc-7.10.1/array_FaHmcBFfuRM8kmZLEY8D5S data-dir: /opt/ghc/7.10.1/share/x86_64-linux-ghc-7.10.1/array-0.5.1.0 hs-libraries: HSarray-0.5.1.0-FaHmcBFfuRM8kmZLEY8D5S depends: base-4.8.0.0-1b689eb8d72c4d4cc88f445839c1f01a haddock-interfaces: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/array-0.5.1.0/array.haddock haddock-html: /opt/ghc/7.10.1/share/doc/ghc/html/libraries/array-0.5.1.0 pkgroot: "/opt/ghc/7.10.1/lib/ghc-7.10.1" --- name: filepath version: 1.4.0.0 id: filepath-1.4.0.0-40d643aa87258c186441a1f8f3e13ca6 key: filep_5HhyRonfEZoDO205Wm9E4h license: BSD3 copyright: Neil Mitchell 2005-2015 maintainer: Neil Mitchell homepage: https://github.com/haskell/filepath#readme synopsis: Library for manipulating FilePaths in a cross platform way. description: This package provides functionality for manipulating @FilePath@ values, and is shipped with both and the .

It can be used on its own in portable Haskell code, or with the monad classes in the @mtl@ or @monads-tf@ packages, which automatically lift operations introduced by monad transformers through other transformers. category: Control author: Andy Gill, Ross Paterson exposed: True exposed-modules: Control.Applicative.Backwards Control.Applicative.Lift Control.Monad.IO.Class Control.Monad.Trans.Class Control.Monad.Trans.Cont Control.Monad.Trans.Error Control.Monad.Trans.Identity Control.Monad.Trans.List Control.Monad.Trans.Maybe Control.Monad.Trans.Reader Control.Monad.Trans.RWS Control.Monad.Trans.RWS.Lazy Control.Monad.Trans.RWS.Strict Control.Monad.Trans.State Control.Monad.Trans.State.Lazy Control.Monad.Trans.State.Strict Control.Monad.Trans.Writer Control.Monad.Trans.Writer.Lazy Control.Monad.Trans.Writer.Strict Data.Functor.Compose Data.Functor.Constant Data.Functor.Identity Data.Functor.Product Data.Functor.Reverse hidden-modules: trusted: False import-dirs: /opt/ghc/7.8.4/lib/ghc-7.8.4/transformers-0.3.0.0 library-dirs: /opt/ghc/7.8.4/lib/ghc-7.8.4/transformers-0.3.0.0 hs-libraries: HStransformers-0.3.0.0 extra-libraries: extra-ghci-libraries: include-dirs: includes: depends: base-4.7.0.2-bfd89587617e381ae01b8dd7b6c7f1c1 hugs-options: cc-options: ld-options: framework-dirs: frameworks: haddock-interfaces: /opt/ghc/7.8.4/share/doc/ghc/html/libraries/transformers-0.3.0.0/transformers.haddock haddock-html: /opt/ghc/7.8.4/share/doc/ghc/html/libraries/transformers-0.3.0.0 pkgroot: "/opt/ghc/7.8.4/lib/ghc-7.8.4" --- name: hoopl version: 3.10.0.1 id: hoopl-3.10.0.1-267659e4b5b51c3d2e02f2a6d6f46936 license: BSD3 copyright: maintainer: nr@cs.tufts.edu stability: homepage: http://ghc.cs.tufts.edu/hoopl/ package-url: synopsis: A library to support dataflow analysis and optimization description: Higher-order optimization library .

The 'ByteString' type represents sequences of bytes or 8-bit characters. It is suitable for high performance use, both in terms of large data quantities, or high speed requirements. The 'ByteString' functions follow the same style as Haskell\'s ordinary lists, so it is easy to convert code from using 'String' to 'ByteString'. . Two 'ByteString' variants are provided: . * Strict 'ByteString's keep the string as a single large array. This makes them convenient for passing data between C and Haskell. . * Lazy 'ByteString's use a lazy list of strict chunks which makes it suitable for I\/O streaming tasks. . The @Char8@ modules provide a character-based view of the same underlying 'ByteString' types. This makes it convenient to handle mixed binary and 8-bit character content (which is common in many file formats and network protocols). . The 'Builder' module provides an efficient way to build up 'ByteString's in an ad-hoc way by repeated concatenation. This is ideal for fast serialisation or pretty printing. . There is also a 'ShortByteString' type which has a lower memory overhead and can be converted to or from a 'ByteString', but supports very few other operations. It is suitable for keeping many short strings in memory. . 'ByteString's are not designed for Unicode. For Unicode strings you should use the 'Text' type from the @text@ package. .

Deep evaluation is often used for adding strictness to a program, e.g. in order to force pending exceptions, remove space leaks, or force lazy I/O to happen. It is also useful in parallel programs, to ensure pending work does not migrate to the wrong thread. . The primary use of this package is via the 'deepseq' function, a \"deep\" version of 'seq'. It is implemented on top of an 'NFData' typeclass (\"Normal Form Data\", data structures with no unevaluated components) which defines strategies for fully evaluating different data types. .

The package can be used on its own in portable Haskell code, in which case operations need to be manually lifted through transformer stacks (see "Control.Monad.Trans.Class" for some examples). Alternatively, it can be used with the non-portable monad classes in the @mtl@ or @monads-tf@ packages, which automatically lift operations introduced by monad transformers through other transformers. category: Control author: Andy Gill, Ross Paterson exposed: True exposed-modules: Control.Applicative.Backwards Control.Applicative.Lift Control.Monad.Signatures Control.Monad.Trans.Class Control.Monad.Trans.Cont Control.Monad.Trans.Except Control.Monad.Trans.Error Control.Monad.Trans.Identity Control.Monad.Trans.List Control.Monad.Trans.Maybe Control.Monad.Trans.Reader Control.Monad.Trans.RWS Control.Monad.Trans.RWS.Lazy Control.Monad.Trans.RWS.Strict Control.Monad.Trans.State Control.Monad.Trans.State.Lazy Control.Monad.Trans.State.Strict Control.Monad.Trans.Writer Control.Monad.Trans.Writer.Lazy Control.Monad.Trans.Writer.Strict Data.Functor.Classes Data.Functor.Compose Data.Functor.Constant Data.Functor.Product Data.Functor.Reverse Data.Functor.Sum abi: d71166f18d2591685ff3ee72b17638c0 trusted: False import-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/transformers-0.4.3.0 library-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/transformers-0.4.3.0 data-dir: /opt/ghc/head/share/x86_64-linux-ghc-7.11.20151213/transformers-0.4.3.0 hs-libraries: HStransformers-0.4.3.0 depends: base-4.9.0.0 haddock-interfaces: /opt/ghc/head/share/doc/ghc/html/libraries/transformers-0.4.3.0/transformers.haddock haddock-html: /opt/ghc/head/share/doc/ghc/html/libraries/transformers-0.4.3.0 --- name: hoopl version: 3.10.2.0 id: hoopl-3.10.2.0 key: hoopl-3.10.2.0 license: BSD3 maintainer: nr@cs.tufts.edu, andreas.voellmy@gmail.com, email@ningwang.org homepage: http://ghc.cs.tufts.edu/hoopl/ synopsis: A library to support dataflow analysis and optimization description: Higher-order optimization library .

The 'ByteString' type represents sequences of bytes or 8-bit characters. It is suitable for high performance use, both in terms of large data quantities, or high speed requirements. The 'ByteString' functions follow the same style as Haskell\'s ordinary lists, so it is easy to convert code from using 'String' to 'ByteString'. . Two 'ByteString' variants are provided: . * Strict 'ByteString's keep the string as a single large array. This makes them convenient for passing data between C and Haskell. . * Lazy 'ByteString's use a lazy list of strict chunks which makes it suitable for I\/O streaming tasks. . The @Char8@ modules provide a character-based view of the same underlying 'ByteString' types. This makes it convenient to handle mixed binary and 8-bit character content (which is common in many file formats and network protocols). . The 'Builder' module provides an efficient way to build up 'ByteString's in an ad-hoc way by repeated concatenation. This is ideal for fast serialisation or pretty printing. . There is also a 'ShortByteString' type which has a lower memory overhead and can be converted to or from a 'ByteString', but supports very few other operations. It is suitable for keeping many short strings in memory. . 'ByteString's are not designed for Unicode. For Unicode strings you should use the 'Text' type from the @text@ package. .

It is implemented on top of an 'NFData' typeclass (\"Normal Form Data\", data structures with no unevaluated components) which defines strategies for fully evaluating different data types. category: Control exposed: True exposed-modules: Control.DeepSeq abi: 63c4c214c0c19484502b3c8b7e42ec69 trusted: False import-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/deepseq-1.4.2.0 library-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/deepseq-1.4.2.0 data-dir: /opt/ghc/head/share/x86_64-linux-ghc-7.11.20151213/deepseq-1.4.2.0 hs-libraries: HSdeepseq-1.4.2.0 depends: array-0.5.1.0 base-4.9.0.0 haddock-interfaces: /opt/ghc/head/share/doc/ghc/html/libraries/deepseq-1.4.2.0/deepseq.haddock haddock-html: /opt/ghc/head/share/doc/ghc/html/libraries/deepseq-1.4.2.0 --- name: array version: 0.5.1.0 id: array-0.5.1.0 key: array-0.5.1.0 license: BSD3 maintainer: libraries@haskell.org synopsis: Mutable and immutable arrays description: In addition to providing the "Data.Array" module , this package also defines the classes 'IArray' of immutable arrays and 'MArray' of arrays mutable within appropriate monads, as well as some instances of these classes. category: Data Structures exposed: True exposed-modules: Data.Array Data.Array.Base Data.Array.IArray Data.Array.IO Data.Array.IO.Safe Data.Array.IO.Internals Data.Array.MArray Data.Array.MArray.Safe Data.Array.ST Data.Array.ST.Safe Data.Array.Storable Data.Array.Storable.Safe Data.Array.Storable.Internals Data.Array.Unboxed Data.Array.Unsafe abi: 2b2b879a09eb81c865ac273803e08132 trusted: False import-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/array-0.5.1.0 library-dirs: /opt/ghc/head/lib/ghc-7.11.20151213/array-0.5.1.0 data-dir: /opt/ghc/head/share/x86_64-linux-ghc-7.11.20151213/array-0.5.1.0 hs-libraries: HSarray-0.5.1.0 depends: base-4.9.0.0 haddock-interfaces: /opt/ghc/head/share/doc/ghc/html/libraries/array-0.5.1.0/array.haddock haddock-html: /opt/ghc/head/share/doc/ghc/html/libraries/array-0.5.1.0 --- name: filepath version: 1.4.1.0 id: filepath-1.4.1.0 key: filepath-1.4.1.0 license: BSD3 copyright: Neil Mitchell 2005-2015 maintainer: Neil Mitchell homepage: https://github.com/haskell/filepath#readme synopsis: Library for manipulating FilePaths in a cross platform way. description: This package provides functionality for manipulating @FilePath@ values, and is shipped with both and the .

GNU LESSER GENERAL PUBLIC LICENSE ================================= Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. ## 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. ## 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. ## 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: - a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or - b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. ## 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: - a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. - b) Accompany the object code with a copy of the GNU GPL and this license document. ## 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: - a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. - b) Accompany the Combined Work with a copy of the GNU GPL and this license document. - c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. - d) Do one of the following: - 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. - 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. - e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) ## 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: - a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. - b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. ## 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library. GNU GENERAL PUBLIC LICENSE ========================== Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. ## Preamble The GNU General Public License is a free, copyleft license for software and other kinds of works. The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things. To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others. For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it. For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions. Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users. Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free. The precise terms and conditions for copying, distribution and modification follow. ## TERMS AND CONDITIONS ### 0. Definitions. "This License" refers to version 3 of the GNU General Public License. "Copyright" also means copyright-like laws that apply to other kinds of works, such as semiconductor masks. "The Program" refers to any copyrightable work licensed under this License. Each licensee is addressed as "you". "Licensees" and "recipients" may be individuals or organizations. To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work. A "covered work" means either the unmodified Program or a work based on the Program. To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well. To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying. An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion. ### 1. Source Code. The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work. A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language. The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work. The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source. The Corresponding Source for a work in source code form is that same work. ### 2. Basic Permissions. All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law. You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary. ### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures. When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures. ### 4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. ### 5. Conveying Modified Source Versions. You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions: - a) The work must carry prominent notices stating that you modified it, and giving a relevant date. - b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices". - c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it. - d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate. ### 6. Conveying Non-Source Forms. You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways: - a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange. - b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. - c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. - d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements. - e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product. "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM). The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying. ### 7. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms: - a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or - b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or - c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or - d) Limiting the use for publicity purposes of names of licensors or authors of the material; or - e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or - f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying. If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms. Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way. ### 8. Termination. You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11). However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice. Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10. ### 9. Acceptance Not Required for Having Copies. You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so. ### 10. Automatic Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts. You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it. ### 11. Patents. A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version". A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it. A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007. Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law. ### 12. No Surrender of Others' Freedom. If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program. ### 13. Use with the GNU Affero General Public License. Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such. ### 14. Revised Versions of this License. The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version. ### 15. Disclaimer of Warranty. THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. ### 16. Limitation of Liability. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. ### 17. Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS ## How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program. If not, see . Also add information on how to contact you by electronic and paper mail. If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode: Copyright (C) This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands \`show w' and \`show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box". You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see . The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read . stack-3.7.1/Setup.hs0000644000000000000000000000765015023557531012467 0ustar0000000000000000module Main ( main ) where import Data.List ( nub, sortOn ) import Distribution.InstalledPackageInfo ( installedUnitId, sourcePackageId ) import Distribution.Package ( UnitId, packageName, packageVersion ) import Distribution.PackageDescription ( Executable (..), PackageDescription ) import Distribution.Pretty ( prettyShow ) import Distribution.Simple ( UserHooks(..), defaultMainWithHooks, simpleUserHooks ) import Distribution.Simple.BuildPaths ( autogenPackageModulesDir ) import Distribution.Simple.LocalBuildInfo ( ComponentLocalBuildInfo (..), LocalBuildInfo, installedPkgs , withExeLBI, withLibLBI ) import Distribution.Simple.PackageIndex ( allPackages, dependencyClosure ) import Distribution.Simple.Setup ( BuildFlags (..), ReplFlags (..), fromFlag ) import Distribution.Simple.Utils ( createDirectoryIfMissingVerbose, rewriteFileEx ) import Distribution.Types.PackageName ( unPackageName ) import Distribution.Types.UnqualComponentName ( unUnqualComponentName ) import Distribution.Verbosity ( Verbosity, normal ) import System.FilePath ( () ) main :: IO () main = defaultMainWithHooks simpleUserHooks { buildHook = \pkg lbi hooks flags -> do generateBuildModule (fromFlag (buildVerbosity flags)) pkg lbi buildHook simpleUserHooks pkg lbi hooks flags -- The 'cabal repl' hook corresponds to the 'cabal build' hook and is added -- because, with a Cabal-based cradle, Haskell Language Server makes use of -- 'cabal repl'. , replHook = \pkg lbi hooks flags args -> do generateBuildModule (fromFlag (replVerbosity flags)) pkg lbi replHook simpleUserHooks pkg lbi hooks flags args } generateBuildModule :: Verbosity -> PackageDescription -> LocalBuildInfo -> IO () generateBuildModule verbosity pkg lbi = do let dir = autogenPackageModulesDir lbi createDirectoryIfMissingVerbose verbosity True dir withLibLBI pkg lbi $ \_ libcfg -> do withExeLBI pkg lbi $ \exe clbi -> do let name = exeName' exe rewriteFileEx normal (dir "Build_" ++ name ++ ".hs") $ unlines [ "{-|" , "Module : Build_" ++ name , "License : BSD-3-Clause" , "-}" , "" , "module Build_" ++ name , " ( deps" , " ) where" , "" , "-- | The dependencies against which \\'" ++ name ++ "\\' is built." , "deps :: [String]" , "deps = " ++ show (formatdeps (transDeps libcfg clbi)) ] where exeName' = unUnqualComponentName . exeName formatdeps = map formatone . sortOn unPackageName' formatone p = unPackageName' p ++ "-" ++ prettyShow (packageVersion p) unPackageName' = unPackageName . packageName transDeps xs ys = either (map sourcePackageId . allPackages) handleDepClosureFailure $ dependencyClosure allInstPkgsIdx availInstPkgIds where allInstPkgsIdx = installedPkgs lbi allInstPkgIds = map installedUnitId $ allPackages allInstPkgsIdx -- instPkgIds includes `stack-X.X.X`, which is not a dependency hence is -- missing from allInstPkgsIdx.
