Fully feature complete YAML parser and emitter, supporting the latest YAML spec and passing the full YAML testsuite. It is designed to be very efficient, avoiding copies of data, and has no artificial limits like the 1024 character limit for implicit keys. libfyaml is using https://github.com/yaml/yaml-test-suite as a core part of it's testsuite. ## Features * Fully supports YAML version 1.2. * Attempts to adhere to features coming with YAML version 1.3 so that it will be ready. * Zero content copy operation, which means that content is never copied to internal structures. On input types that support it (mmap files and constant strings) that means that memory usage is kept low, and arbitrary large content can be manipulated without problem. * Parser may be used in event mode (like libyaml) or in document generating mode. * Extensive programmable API capable of manipulating parsed YAML documents or creating them from scratch. * YAML emitter with programmable options, supporting colored output. * Extensive testsuite for the API, the full YAML test-suite and correct emitter operation. * Easy printf/scanf based YAML creation and data extraction API. * Accurate and descriptive error messages, in standard compiler format that can be parsed by editors and developer GUIs. * Testsuite supports running under valgrind and checking for memory leaks. No leaks should be possible under normal operation, so it is usable for long- running applications. ## Contents - [Features](#features) - [Prerequisites](#prerequisites) - [Building](#building) - [Usage and examples](#usage-and-examples) - [API documentation](#api-documentation) - [fy-tool reference](#fy-tool-reference) - [Missing Features](#missing-features) ## Prerequisites libfyaml is primarily developed on Linux based debian distros but Apple MacOS X builds (using homebrew) are supported as well. On a based debian distro (i.e. ubuntu 19.04 disco) you should install the following dependencies: * `sudo apt-get install gcc autoconf automake libtool git make libltdl-dev pkg-config` To enable the libyaml comparison checker: * `sudo apt-get install libyaml-dev` For the API testsuite libcheck is required: * `sudo apt-get install check` And finally in order to build the sphinx based documentation: * `sudo apt-get install python3 python3-pip python3-setuptools` * `pip3 install wheel sphinx git+http://github.com/return42/linuxdoc.git sphinx\_rtd\_theme sphinx-markdown-builder` Note that some older distros (like xenial) do not have a sufficiently recent sphinx in their repos. In that case you can create a virtual environment using scripts/create-virtual-env ## Building ``libfyaml`` uses a standard autotools based build scheme so: * `./bootstrap.sh` * `./configure` * `make` Will build the library and `fy-tool`. * `make check` Will run the test-suite. Binaries, libraries, header files and pkgconfig files maybe installed with * `make install` By default, the installation prefix will be `/usr/local`, which you can change with the `--prefix ` option during configure. To build the documentation API in HTML format use: * `make doc-html` The documentation for the public API will be found in doc/\_build/html * `make doc-latexpdf` Will generate a single pdf containing everything. ## Usage and examples Usage of libfyaml is somewhat similar to libyaml, but with a few notable differences. 1. The objects of the library are opaque, they are pointers that may be used but may not be derefenced via library users. This makes the public API not be dependent of internal changes in the library structures. 2. The object pointers used are guaranteed to not 'move' like libyaml object pointers so you may embed them freely in your own structures. 3. The convenience methods of libyaml allow you to avoid tedious iteration and code duplication. While fully manual YAML document tree manipulation is available, if your application is not performance sensitive when manipulating YAML, you are advised to use the helpers. ### Using libfyaml in your projects Typically you only have to include the single header file `libfyaml.h` and link against the correct fyaml-\-\ library. It is recommended to use pkg-config, i.e. ```make CFLAGS+= `pkg-config --cflags libfyaml` LDFLAGS+= `pkg-config --libs libfyaml` ``` For use in an automake based project you may use the following fragment ```bash PKG_CHECK_MODULES(LIBFYAML, [ libfyaml ], HAVE_LIBFYAML=1, HAVE_LIBFYAML=0) if test "x$HAVE_LIBFYAML" != "x1" ; then AC_MSG_ERROR([failed to find libfyaml]) fi AC_SUBST(HAVE_LIBFYAML) AC_SUBST(LIBFYAML_CFLAGS) AC_SUBST(LIBFYAML_LIBS) AC_DEFINE_UNQUOTED([HAVE_LIBFYAML], [$HAVE_LIBFYAML], [Define to 1 if you have libfyaml available]) AM_CONDITIONAL([HAVE_LIBFYAML], [ test x$HAVE_LIBFYAML = x1 ]) ``` The examples that follow will make things clear. ### Display libfyaml version example This is the minimal example that checks that you've compiled against the correct libfyaml. ```c /* * fy-version.c - libfyaml version example * * Copyright (c) 2019 Pantelis Antoniou * * SPDX-License-Identifier: MIT */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include #include #include int main(int argc, char *argv[]) { printf("%s\n", fy_library_version()); return EXIT_SUCCESS; } ``` ### libfyaml example using simplified inprogram YAML generation This example simply parses an in-program YAML string and displays a string. The standard header plus variables definition. ```c /* * inprogram.c - libfyaml inprogram YAML example * * Copyright (c) 2019 Pantelis Antoniou * * SPDX-License-Identifier: MIT */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include #include #include #include int main(int argc, char *argv[]) { static const char *yaml = "invoice: 34843\n" "date : !!str 2001-01-23\n" "bill-to: &id001\n" " given : Chris\n" " family : Dumars\n" " address:\n" " lines: |\n" " 458 Walkman Dr.\n" " Suite #292\n"; struct fy_document *fyd = NULL; int rc, count, ret = EXIT_FAILURE; unsigned int invoice_nr; char given[256 + 1]; ``` Parsing and creating a YAML document from either the built-in YAML, or an invoice file given on the command line: ```c if (argc == 1) fyd = fy_document_build_from_string(NULL, yaml, FY_NT); else fyd = fy_document_build_from_file(NULL, argv[1]); if (!fyd) { fprintf(stderr, "failed to build document"); goto fail; } ``` Get the invoice number and the given name using a single call. ```c /* get the invoice number and the given name */ count = fy_document_scanf(fyd, "/invoice %u " "/bill-to/given %256s", &invoice_nr, given); if (count != 2) { fprintf(stderr, "Failed to retreive the two items\n"); goto fail; } /* print them as comments in the emitted YAML */ printf("# invoice number was %u\n", invoice_nr); printf("# given name is %s\n", given); ``` In sequence, increase the invoice number, add a spouse and a secondary address. ```c rc = /* set increased invoice number (modify existing node) */ fy_document_insert_at(fyd, "/invoice", FY_NT, fy_node_buildf(fyd, "%u", invoice_nr + 1)) || /* add spouse (create new mapping pair) */ fy_document_insert_at(fyd, "/bill-to", FY_NT, fy_node_buildf(fyd, "spouse: %s", "Doris")) || /* add a second address */ fy_document_insert_at(fyd, "/bill-to", FY_NT, fy_node_buildf(fyd, "delivery-address:\n" " lines: |\n" " 1226 Windward Ave.\n")); if (rc) { fprintf(stderr, "failed to insert to document\n"); goto fail; } ``` Emit the document to standard output (while sorting the keys) ```c /* emit the document to stdout (but sorted) */ rc = fy_emit_document_to_fp(fyd, FYECF_DEFAULT | FYECF_SORT_KEYS, stdout); if (rc) { fprintf(stderr, "failed to emit document to stdout"); goto fail; } ``` Finally exit and report condition. ```c ret = EXIT_SUCCESS; fail: fy_document_destroy(fyd); /* NULL is OK */ return ret; } ``` ## API documentation For complete documentation of libfyaml API, visit https://pantoniou.github.io/libfyaml/ ## fy-tool reference A YAML manipulation tool is included in libfyaml, aptly name `fy-tool`. It's a multi tool application, acting differently according to the name it has when it's invoked. There are four tool modes, namely: * fy-testsuite: Used for outputing a test-suite specific event stream which is used for comparison with the expected output of the suite. * fy-dump: General purpose YAML parser and dumper, with syntax coloring support, visible whitespace options, and a number of output modes. * fy-filter: YAML filtering tool allows to extract information out of a YAML document. * fy-join: YAML flexible join tool. ### fy-testsuite usage A number of options are common in every fy-tool invocation: ``` Usage : fy-tool [options] [args] Options: --include, -I : Add directory to include path (default path "") --debug-level, -d : Set debug level to (default level 3) --indent, -i : Set dump indent to (default indent 2) --width, -w : Set dump width to (default width 80) --resolve, -r : Perform anchor and merge key resolution (default false) --color, -C : Color output can be one of on, off, auto (default auto) --visible, -V : Make all whitespace and linebreaks visible (default false) --follow, -l : Follow aliases when using paths (default false) --strip-labels : Strip labels when emitting (default false) --strip-tags : Strip tags when emitting (default false) --strip-doc : Strip document headers and indicators when emitting (default false) --quiet, -q : Quiet operation, do not output messages (default false) --version, -v : Display libfyaml version --help, -h : Display help message ``` ``` Usage: fy-testsuite [options] [args] [common options] Parse and dump test-suite event format $ fy-testsuite input.yaml ... Parse and dump of event example $ echo "foo: bar" | fy-testsuite - +STR +DOC +MAP =VAL :foo =VAL :bar -MAP -DOC -STR ``` ### fy-dump usage ``` Usage: fy-dump [options] [args] Options: [common options] --sort, -s : Perform mapping key sort (valid for dump) (default false) --comment, -c : Output comments (experimental) (default false) --mode, -m : Output mode can be one of original, block, flow, flow-oneline, json, json-tp, json-oneline (default original) --streaming : Use streaming output mode (default false) [common options] Parse and dump generated YAML document tree in the original YAML form $ fy-dump input.yaml ... Parse and dump generated YAML document tree in block YAML form (and make whitespace visible) $ fy-dump -V -mblock input.yaml ... Parse and dump generated YAML document from the input string $ fy-dump -mjson ">foo: bar" { "foo": "bar" } Parse and dump generated YAML document from the input string (using streaming mode) $ fy-dump --streaming ">foo: bar" foo: bar Note that streaming mode can not perform document validity checks, like duplicate keys nor support the sort keys option. ``` ### fy-filter usage ``` Usage: fy-filter [options] [args] Options: [common options] --sort, -s : Perform mapping key sort (valid for dump) (default false) --comment, -c : Output comments (experimental) (default false) --mode, -m : Output mode can be one of original, block, flow, flow-oneline, json, json-tp, json-oneline (default original) --file, -f : Use given file instead of Note that using a string with a leading '>' is equivalent to a file with the trailing content --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar" Parse and filter YAML document tree starting from the '/foo' path followed by the '/bar' path $ fy-filter --file input.yaml /foo /bar ... Parse and filter for two paths (note how a multi-document stream is produced) $ fy-filter --file -mblock --filter --file ">{ foo: bar, baz: [ frooz, whee ] }" /foo /baz bar --- - frooz - whee Parse and filter YAML document in stdin (note how the key may be complex) $ echo "{ foo: bar }: baz" | fy-filter "/{foo: bar}/" baz ``` ### fy-join usage ``` Usage: fy-join [options] [args] Options: [common options] --sort, -s : Perform mapping key sort (valid for dump) (default false) --comment, -c : Output comments (experimental) (default false) --mode, -m : Output mode can be one of original, block, flow, flow-oneline, json, json-tp, json-oneline (default original) --file, -f : Use given file instead of Note that using a string with a leading '>' is equivalent to a file with the trailing content --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar" --to, -T : Join to (default /) --from, -F : Join from (default /) --trim, -t : Output given path (default /) Parse and join two YAML files $ fy-join file1.yaml file2.yaml ... Parse and join two YAML maps $ fy-join ">foo: bar" ">baz: frooz" foo: bar baz: frooz ``` ## Missing features and omissions 1. Windows - libfyaml is not supporting windows yet. 2. Unicode - libfyaml only supports UTF8 and has no support for wide character input. ## Development and contributing Feel free to send pull requests and raise issues. libfyaml-0.7.12/src/0000775000175000017500000000000014171764653011210 500000000000000libfyaml-0.7.12/src/lib/0000775000175000017500000000000014171764653011756 500000000000000libfyaml-0.7.12/src/lib/fy-docbuilder.h0000664000175000017500000000430614170030555014564 00000000000000/* * fy-docbuilder.h - YAML document builder internal header file * * Copyright (c) 2022 Pantelis Antoniou * * SPDX-License-Identifier: MIT */ #ifndef FY_DOCBUILDER_H #define FY_DOCBUILDER_H #ifdef HAVE_CONFIG_H #include "config.h" #endif #include #include #include #include #include #include "fy-doc.h" enum fy_document_builder_state { FYDBS_NODE, FYDBS_MAP_KEY, FYDBS_MAP_VAL, FYDBS_SEQ, };

* * DESCRIPTION * The open_memstream() function opens a stream for writing to a buffer. * The buffer is dynamically allocated (as with malloc(3)), and * automatically grows as required. After closing the stream, the caller * should free(3) this buffer. * * When the stream is closed (fclose(3)) or flushed (fflush(3)), the * locations pointed to by bufp and sizep are updated to contain, * respectively, a pointer to the buffer and the current size of the * buffer. These values remain valid only as long as the caller performs * no further output on the stream. If further output is performed, then * the stream must again be flushed before trying to access these * variables. * * A null byte is maintained at the end of the buffer. This byte is not * included in the size value stored at sizep. * * The stream's file position can be changed with fseek(3) or fseeko(3). * Moving the file position past the end of the data already written fills * the intervening space with zeros. * * RETURN VALUE * Upon successful completion open_memstream() returns a FILE pointer. * Otherwise, NULL is returned and errno is set to indicate the error. * * CONFORMING TO * POSIX.1-2008 * * ---------------------------------------------------------------------------- */ #ifndef min #define min(X, Y) (((X) < (Y)) ?

Also, it might not be ## supported by the other compilers which use the 'gcc' depmode. ## - Using -M directly means running the compiler twice (even worse ## than renaming). if test -z "$gccflag"; then gccflag=-MD, fi "$@" -Wp,"$gccflag$tmpdepfile" stat=$? if test $stat -ne 0; then rm -f "$tmpdepfile" exit $stat fi rm -f "$depfile" echo "$object : \\" > "$depfile" # The second -e expression handles DOS-style file names with drive # letters. sed -e 's/^[^:]*: / /' \ -e 's/^['$alpha']:\/[^:]*: / /' < "$tmpdepfile" >> "$depfile" ## This next piece of magic avoids the "deleted header file" problem. ## The problem is that when a header file which appears in a .P file ## is deleted, the dependency causes make to die (because there is ## typically no way to rebuild the header). We avoid this by adding ## dummy dependencies for each header file. Too bad gcc doesn't do ## this for us directly. ## Some versions of gcc put a space before the ':'. On the theory ## that the space means something, we add a space to the output as ## well. hp depmode also adds that space, but also prefixes the VPATH ## to the object. Take care to not repeat it in the output. ## Some versions of the HPUX 10.20 sed can't process this invocation ## correctly.

Its operation is different depending on how it's called, either via aliases named `fy-dump`, `fy-testsuite`, `fy-filter`, `fy-join`, or via the `--dump`, `--testsuite`, `--filter`, `--join`, `--ypath` and `--compose` options. * In `dump` mode it will parse YAML/JSON input files and output YAML/JSON according to the output format options. * In `testsuite` mode it will parse a single YAML input file and output yaml testsuite reference output. * In `filter` mode it will parse YAML/JSON files and output YAML/JSON output filtered according to the given option. * In `join` mode it will parse YAML/JSON files and join them into a single YAML/JSON document according to the given command line options. * In `ypath` mode it will parse YAML/JSON files and execute a ypath query which will output a document stream according to the results. This is an experimental mode under development, where the syntax is not yet decided completely. * In `compose` mode, it operates similarly to dump, but the document tree is created using the built-in composer API. Options ------- .. program:: fy-tool A number of options are common for all the different modes of operation and they are as follows: .. rubric:: Common options .. option:: -q, --quiet Quiet operation, does not output informational messages at all. .. option:: -h, --help Display usage information. .. option:: -v, --version Display version information. .. option:: -I DIR, --include=DIR Add the `DIR` directory to the search path which will be used to locate a YAML/JSON file. The default path is set to "" .. option:: -d LEVEL, --debug-level=LEVEL Set the minimum numeric debug level value of the library to `LEVEL`. The numeric value must be in the range of 0 to 4 and their meaning is as follows: - **0** (`DEBUG`) Internal library debugging messages. No output is produced when the library was compiled with `--disable-debug` - **1** (`INFO`) Informational messages about the internal operation of the library. - **2** (`NOTICE`) Messsages that could require attention. - **3** (`WARNING`) A warning message, something is wrong, but operation can continue. This is the default value. - **4** (`ERROR`) A fatal error occured, it is impossible to continue. The default level is 3 (`WARNING`), which means that messages with level 3 and higher will be displayed. .. rubric:: Parser Options .. option:: -j JSONOPT, --json=JSONOPT Marks the input files as JSON or YAML accordingly to: - **no** The input files are always in YAML mode. - **force** The input files are always set to JSON mode. - **auto** The input files are set to JSON mode automatically when the file's extension is `.json`. This is the default. JSON support is complete so all valid JSON files are parsed according to JSON rules, even where those differ with YAML rules. .. option:: --yaml-1.1 Force YAML 1.1 rules, when input does not specify a version via a directive. .. option:: --yaml-1.2 Force YAML 1.2 rules, when input does not specify a version via a directive. .. option:: --yaml-1.3 Force YAML 1.3 rules, when input does not specify a version via a directive. This option is experimental since the 1.3 spec is not yet released. .. option:: --disable-accel Disable use of acceleration features; use less memory but potentially more CPU. .. option:: --disable-buffering Disable use stdio bufferring, reads will be performed via unix fd reads. This may reduce latency when reading from a network file descriptor, or similar. .. option:: --disable-depth-limit Disable the object depth limit, which is usually set to a value near 60. Using this option is is possible to process even pathological inputs when using the default non-recursive build mode. .. option:: --prefer-recursive Prefer recursive build methods, instead of iterative. This field is merely here for evaluation purposes and will be removed in a future version. .. option:: --sloppy-flow-indentation Use sloppy flow indentation, where indentation is not taken into account in flow mode, even when the input is invalid YAML according to the spec. .. option:: --ypath-aliases Process aliases using ypaths. Experimental option. .. option:: --streaming Only valid when in **dump** mode, enables streaming mode. This means that no in-memory graph tree is constructed, so indefinite and arbitrary large YAML input streams can be processed. Note that in streaming mode: - Key duplication checks are disabled. - No reording of key order is possible when emitting (i.e. `--sort` is not available). - Alias resolution is not available (i.e. `--resolve`). .. rubric:: Resolver Options .. option:: -r, --resolve Perform anchor and merge key resolution. By default this option is disabled. .. option:: -l, --follow Follow aliases when performing path traversal. By default this option is disabled. .. rubric:: Testsuite Options .. option:: --disable-flow-markers Do not output flow-markers for the testsuite output. .. rubric:: Emitter Options .. option:: -i INDENT, --indent=INDENT Sets the emitter indent (in spaces). Default is **2**. .. option:: -w WIDTH, --width=WIDTH Sets the preferred output width of the emitter. It is generally impossible to strictly adhere to this limit so this is treated as a hint at best. It not valid in any oneline output modes (i.e. `flow-oneline` or `json-oneline`). Default value is 80. .. option:: -m MODE, --mode=MODE Sets the output mode of the YAML emitted. Possible values are: - **original** The original formatting used in the input. This is default mode. - **block** The output is forced to be in block mode. All flow constructs will be converted to block mode. - **flow** The output is forced to be in flow mode. All block constructs will be converted to flow mode. - **flow-oneline** The output is forced to be in flow mode, but no newlines will be emitted; the output is going to be a (potentially very) long line. - **json** The output is forced to be in JSON mode. Note that it is impossible to output an arbitrary YAML file as JSON, so this may fail. - **json-oneline** The output is forced to be in JSON mode and in a single line. - **dejson** Output is in block YAML mode but with special care to convert JSON quoted strings in as non-idiomatic YAML as possible. For example `{ foo: "this is a test" }` will be emitted as `foo: this is a test`. YAML can handle scalars without using excessive quoting. .. option:: -C MODE, --color=MODE It is possible to colorize output using ANSI color escape sequences, and the mode can be one of: - **off** Never colorize output. - **on** Always colorize output. - **auto** Automatically colorize output when the output is a terminal. This is the default. .. option:: -V, --visible Make all whitespace (spaces, unicode spaces and linebreaks) visible. Note that this is performed using UTF8 characters so it will not work on non-UTF8 terminals, or a non-UTF8 complete font. .. option:: -s, --sort Sort keys on output. This option is disabled by default. .. option:: -c, --comment Experimental output comments option. Enabled output while preserving comments. Disabled by default. .. option:: --strip-labels Strip labels on output. Disabled by default. .. option:: --strip-tags Strip tags on output. Disabled by default. .. option:: --strip-doc Strip document indicators on output. Disabled by default. .. option:: --null-output Do not generate any output, useful for profiling the parser. .. rubric:: YPATH options .. option:: --dump-pathexpr Dump the produced path expression for debugging. .. option:: --no-exec Do not execute the expression. Useful when used with `--dump-pathexpr` .. rubric:: Compose options .. option:: --dump-path Dump the path while composing. .. rubric:: Tool mode select options .. option:: --dump Select `dump` mode of operation. This is the default. This mode is also enabled when the called binary is aliased to *fy-dump*. In this mode, all files provided in the command line will be dumped in one continuous stream, to the standard output, using document start indicators to mark the start of end new file. If the file provided is `-` then the input is the standard input. .. option:: --testsuite Select `testsuite` mode of operation. This mode is also enabled when the called binary is aliased to *fy-testsuite*. In this mode, a single YAML file is read and an event stream is generated which is the format used for *yaml-testsuite* compliance. If the file provided is `-` then the input is the standard input. .. option:: --filter Select `filter` mode of operation. This mode is also enabled when the called binary is aliased to *fy-filter*. In this mode, a single YAML file is read from the standard input for each path that is provided in the command line a document will be produced to the standard output. To use file instead of standard input use the `-f/--file` option. If the file provided is `-` then the input is the standard input. .. option:: -f FILE, --file=FILE Use the given file as input instead of standard input. If first character of `FILE` is **>** the the input is the content of the option that follows. For example --file ">foo: bar" is as --file file.yaml with file.yaml "foo: bar" .. option:: --join Select `join` mode of operation. This mode is also enabled when the called binary is aliased to *fy-join*. In this mode, multiple YAML files are joined into a single document, emitted to the standard output. If the file provided is `-` then the input is the standard input. .. option:: -T PATH, --to=PATH The target path of the join. By default this is the root **/**. If first character of `FILE` is **>** the the input is the content of the option that follows. .. option:: -F PATH, --from=PATH The origin path of the join (for each input). By default this is the root **/**. If first character of `FILE` is **>** the the input is the content of the option that follows. .. option:: -t PATH, --trim=PATH Trim path of the output of the join. By default this is the root **/**. If first character of `FILE` is **>** the the input is the content of the option that follows. .. option:: --ypath Process files and output query results using ypath. .. option:: --compose Use the composer API to build the document instead of direct events.

Its operation is different depending on how it\(aqs called, either via aliases named \fIfy\-dump\fP, \fIfy\-testsuite\fP, \fIfy\-filter\fP, \fIfy\-join\fP, or via the \fI\-\-dump\fP, \fI\-\-testsuite\fP, \fI\-\-filter\fP, \fI\-\-join\fP, \fI\-\-ypath\fP and \fI\-\-compose\fP options. .INDENT 0.0 .IP \(bu 2 In \fIdump\fP mode it will parse YAML/JSON input files and output YAML/JSON according to the output format options. .IP \(bu 2 In \fItestsuite\fP mode it will parse a single YAML input file and output yaml testsuite reference output. .IP \(bu 2 In \fIfilter\fP mode it will parse YAML/JSON files and output YAML/JSON output filtered according to the given option. .IP \(bu 2 In \fIjoin\fP mode it will parse YAML/JSON files and join them into a single YAML/JSON document according to the given command line options. .IP \(bu 2 In \fIypath\fP mode it will parse YAML/JSON files and execute a ypath query which will output a document stream according to the results. This is an experimental mode under development, where the syntax is not yet decided completely. .IP \(bu 2 In \fIcompose\fP mode, it operates similarly to dump, but the document tree is created using the built\-in composer API. .UNINDENT .SH OPTIONS .sp A number of options are common for all the different modes of operation and they are as follows: Common options.INDENT 0.0 .TP .B \-q, \-\-quiet Quiet operation, does not output informational messages at all. .UNINDENT .INDENT 0.0 .TP .B \-h, \-\-help Display usage information. .UNINDENT .INDENT 0.0 .TP .B \-v, \-\-version Display version information. .UNINDENT .INDENT 0.0 .TP .B \-I DIR, \-\-include=DIR Add the \fIDIR\fP directory to the search path which will be used to locate a YAML/JSON file. The default path is set to "" .UNINDENT .INDENT 0.0 .TP .B \-d LEVEL, \-\-debug\-level=LEVEL Set the minimum numeric debug level value of the library to \fILEVEL\fP\&. The numeric value must be in the range of 0 to 4 and their meaning is as follows: .INDENT 7.0 .IP \(bu 2 \fB0\fP (\fIDEBUG\fP) .sp Internal library debugging messages. No output is produced when the library was compiled with \fI\-\-disable\-debug\fP .IP \(bu 2 \fB1\fP (\fIINFO\fP) .sp Informational messages about the internal operation of the library. .IP \(bu 2 \fB2\fP (\fINOTICE\fP) .sp Messsages that could require attention. .IP \(bu 2 \fB3\fP (\fIWARNING\fP) .sp A warning message, something is wrong, but operation can continue. This is the default value. .IP \(bu 2 \fB4\fP (\fIERROR\fP) .sp A fatal error occured, it is impossible to continue. .UNINDENT .sp The default level is 3 (\fIWARNING\fP), which means that messages with level 3 and higher will be displayed. .UNINDENT Parser Options.INDENT 0.0 .TP .B \-j JSONOPT, \-\-json=JSONOPT Marks the input files as JSON or YAML accordingly to: .INDENT 7.0 .IP \(bu 2 \fBno\fP .sp The input files are always in YAML mode. .IP \(bu 2 \fBforce\fP .sp The input files are always set to JSON mode. .IP \(bu 2 \fBauto\fP .sp The input files are set to JSON mode automatically when the file\(aqs extension is \fI\&.json\fP\&. This is the default. .UNINDENT .sp JSON support is complete so all valid JSON files are parsed according to JSON rules, even where those differ with YAML rules. .UNINDENT .INDENT 0.0 .TP .B \-\-yaml\-1.1 Force YAML 1.1 rules, when input does not specify a version via a directive. .UNINDENT .INDENT 0.0 .TP .B \-\-yaml\-1.2 Force YAML 1.2 rules, when input does not specify a version via a directive. .UNINDENT .INDENT 0.0 .TP .B \-\-yaml\-1.3 Force YAML 1.3 rules, when input does not specify a version via a directive. This option is experimental since the 1.3 spec is not yet released. .UNINDENT .INDENT 0.0 .TP .B \-\-disable\-accel Disable use of acceleration features; use less memory but potentially more CPU. .UNINDENT .INDENT 0.0 .TP .B \-\-disable\-buffering Disable use stdio bufferring, reads will be performed via unix fd reads. This may reduce latency when reading from a network file descriptor, or similar. .UNINDENT .INDENT 0.0 .TP .B \-\-disable\-depth\-limit Disable the object depth limit, which is usually set to a value near 60. Using this option is is possible to process even pathological inputs when using the default non\-recursive build mode. .UNINDENT .INDENT 0.0 .TP .B \-\-prefer\-recursive Prefer recursive build methods, instead of iterative. This field is merely here for evaluation purposes and will be removed in a future version. .UNINDENT .INDENT 0.0 .TP .B \-\-sloppy\-flow\-indentation Use sloppy flow indentation, where indentation is not taken into account in flow mode, even when the input is invalid YAML according to the spec. .UNINDENT .INDENT 0.0 .TP .B \-\-ypath\-aliases Process aliases using ypaths. Experimental option. .UNINDENT .INDENT 0.0 .TP .B \-\-streaming Only valid when in \fBdump\fP mode, enables streaming mode. This means that no in\-memory graph tree is constructed, so indefinite and arbitrary large YAML input streams can be processed. .sp Note that in streaming mode: .INDENT 7.0 .IP \(bu 2 Key duplication checks are disabled. .IP \(bu 2 No reording of key order is possible when emitting (i.e. \fI\-\-sort\fP is not available). .IP \(bu 2 Alias resolution is not available (i.e. \fI\-\-resolve\fP). .UNINDENT .UNINDENT Resolver Options.INDENT 0.0 .TP .B \-r, \-\-resolve Perform anchor and merge key resolution. By default this option is disabled. .UNINDENT .INDENT 0.0 .TP .B \-l, \-\-follow Follow aliases when performing path traversal. By default this option is disabled. .UNINDENT Testsuite Options.INDENT 0.0 .TP .B \-\-disable\-flow\-markers Do not output flow\-markers for the testsuite output. .UNINDENT Emitter Options.INDENT 0.0 .TP .B \-i INDENT, \-\-indent=INDENT Sets the emitter indent (in spaces). Default is \fB2\fP\&. .UNINDENT .INDENT 0.0 .TP .B \-w WIDTH, \-\-width=WIDTH Sets the preferred output width of the emitter. It is generally impossible to strictly adhere to this limit so this is treated as a hint at best. It not valid in any oneline output modes (i.e. \fIflow\-oneline\fP or \fIjson\-oneline\fP). Default value is 80. .UNINDENT .INDENT 0.0 .TP .B \-m MODE, \-\-mode=MODE Sets the output mode of the YAML emitted. Possible values are: .INDENT 7.0 .IP \(bu 2 \fBoriginal\fP .sp The original formatting used in the input. This is default mode. .IP \(bu 2 \fBblock\fP .sp The output is forced to be in block mode. All flow constructs will be converted to block mode. .IP \(bu 2 \fBflow\fP .sp The output is forced to be in flow mode. All block constructs will be converted to flow mode. .IP \(bu 2 \fBflow\-oneline\fP .sp The output is forced to be in flow mode, but no newlines will be emitted; the output is going to be a (potentially very) long line. .IP \(bu 2 \fBjson\fP .sp The output is forced to be in JSON mode. Note that it is impossible to output an arbitrary YAML file as JSON, so this may fail. .IP \(bu 2 \fBjson\-oneline\fP .sp The output is forced to be in JSON mode and in a single line. .IP \(bu 2 \fBdejson\fP .sp Output is in block YAML mode but with special care to convert JSON quoted strings in as non\-idiomatic YAML as possible. For example \fI{ foo: "this is a test" }\fP will be emitted as \fIfoo: this is a test\fP\&. YAML can handle scalars without using excessive quoting. .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-C MODE, \-\-color=MODE It is possible to colorize output using ANSI color escape sequences, and the mode can be one of: .INDENT 7.0 .IP \(bu 2 \fBoff\fP .sp Never colorize output. .IP \(bu 2 \fBon\fP .sp Always colorize output. .IP \(bu 2 \fBauto\fP .sp Automatically colorize output when the output is a terminal. This is the default. .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-V, \-\-visible Make all whitespace (spaces, unicode spaces and linebreaks) visible. Note that this is performed using UTF8 characters so it will not work on non\-UTF8 terminals, or a non\-UTF8 complete font. .UNINDENT .INDENT 0.0 .TP .B \-s, \-\-sort Sort keys on output. This option is disabled by default. .UNINDENT .INDENT 0.0 .TP .B \-c, \-\-comment Experimental output comments option. Enabled output while preserving comments. Disabled by default. .UNINDENT .INDENT 0.0 .TP .B \-\-strip\-labels Strip labels on output. Disabled by default. .UNINDENT .INDENT 0.0 .TP .B \-\-strip\-tags Strip tags on output. Disabled by default. .UNINDENT .INDENT 0.0 .TP .B \-\-strip\-doc Strip document indicators on output. Disabled by default. .UNINDENT .INDENT 0.0 .TP .B \-\-null\-output Do not generate any output, useful for profiling the parser. .UNINDENT YPATH options.INDENT 0.0 .TP .B \-\-dump\-pathexpr Dump the produced path expression for debugging. .UNINDENT .INDENT 0.0 .TP .B \-\-no\-exec Do not execute the expression. Useful when used with \fI\-\-dump\-pathexpr\fP .UNINDENT Compose options.INDENT 0.0 .TP .B \-\-dump\-path Dump the path while composing. .UNINDENT Tool mode select options.INDENT 0.0 .TP .B \-\-dump Select \fIdump\fP mode of operation. This is the default. This mode is also enabled when the called binary is aliased to \fIfy\-dump\fP\&. .sp In this mode, all files provided in the command line will be dumped in one continuous stream, to the standard output, using document start indicators to mark the start of end new file. .sp If the file provided is \fI\-\fP then the input is the standard input. .UNINDENT .INDENT 0.0 .TP .B \-\-testsuite Select \fItestsuite\fP mode of operation. This mode is also enabled when the called binary is aliased to \fIfy\-testsuite\fP\&. .sp In this mode, a single YAML file is read and an event stream is generated which is the format used for \fIyaml\-testsuite\fP compliance. .sp If the file provided is \fI\-\fP then the input is the standard input. .UNINDENT .INDENT 0.0 .TP .B \-\-filter Select \fIfilter\fP mode of operation. This mode is also enabled when the called binary is aliased to \fIfy\-filter\fP\&. .sp In this mode, a single YAML file is read from the standard input for each path that is provided in the command line a document will be produced to the standard output. To use file instead of standard input use the \fI\-f/\-\-file\fP option. .sp If the file provided is \fI\-\fP then the input is the standard input. .INDENT 7.0 .TP .B \-f FILE, \-\-file=FILE Use the given file as input instead of standard input. .sp If first character of \fIFILE\fP is \fB>\fP the the input is the content of the option that follows. For example \-\-file ">foo: bar" is as \-\-file file.yaml with file.yaml "foo: bar" .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-\-join Select \fIjoin\fP mode of operation. This mode is also enabled when the called binary is aliased to \fIfy\-join\fP\&. .sp In this mode, multiple YAML files are joined into a single document, emitted to the standard output. .sp If the file provided is \fI\-\fP then the input is the standard input. .INDENT 7.0 .TP .B \-T PATH, \-\-to=PATH The target path of the join. By default this is the root \fB/\fP\&. .sp If first character of \fIFILE\fP is \fB>\fP the the input is the content of the option that follows. .UNINDENT .INDENT 7.0 .TP .B \-F PATH, \-\-from=PATH The origin path of the join (for each input). By default this is the root \fB/\fP\&. .sp If first character of \fIFILE\fP is \fB>\fP the the input is the content of the option that follows. .UNINDENT .INDENT 7.0 .TP .B \-t PATH, \-\-trim=PATH Trim path of the output of the join. By default this is the root \fB/\fP\&. .sp If first character of \fIFILE\fP is \fB>\fP the the input is the content of the option that follows. .UNINDENT .UNINDENT .INDENT 0.0 .TP .B \-\-ypath Process files and output query results using ypath. .UNINDENT .INDENT 0.0 .TP .B \-\-compose Use the composer API to build the document instead of direct events. .UNINDENT .SH EXAMPLES Example input files .sp

(Warnings, # however, are ignored.) # # ACTION-SUCCESS/ACTION-FAILURE are shell commands to execute on # success/failure. # # If EXTRA-FLAGS is defined, it is added to the current language's default # flags (e.g. CFLAGS) when the check is done. The check us thus made # with the following flags: "CFLAGS EXTRA-FLAGS FLAG". EXTRA-FLAGS can # for example be used to force the compiler to issue an error when a bad # flag is given. # # AX_APPEND_FLAG appends the FLAG to the FLAG-VARIABLE shell variable or # the current language's flags if not specified. FLAG is not added to # FLAG-VARIABLE if it is already in the shell variable. # # AX_APPEND_COMPILE_FLAGS checks for each FLAG1, FLAG2, etc. using # AX_CHECK_COMPILE_FLAG and if the check is successful the flag is added # to the appropriate FLAGS variable with AX_APPEND_FLAG. The # FLAGS-VARIABLE and EXTRA-FLAGS arguments are the same as in the other # macros. AX_APPEND_LINK_FLAGS does the same for linker flags. # # NOTE: Based on AX_CHECK_COMPILER_FLAGS and AX_CFLAGS_GCC_OPTION. # # LICENSE # # Copyright (c) 2008 Guido U.

It # sets the PTHREAD_LIBS output variable to the threads library and linker # flags, and the PTHREAD_CFLAGS output variable to any special C compiler # flags that are needed. (The user can also force certain compiler # flags/libs to be tested by setting these environment variables.) # # Also sets PTHREAD_CC to any special C compiler that is needed for # multi-threaded programs (defaults to the value of CC otherwise). (This # is necessary on AIX to use the special cc_r compiler alias.) # # NOTE: You are assumed to not only compile your program with these flags, # but also link it with them as well. e.g. you should link with # $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS # # If you are only building threads programs, you may wish to use these # variables in your default LIBS, CFLAGS, and CC: # # LIBS="$PTHREAD_LIBS $LIBS" # CFLAGS="$CFLAGS $PTHREAD_CFLAGS" # CC="$PTHREAD_CC" # # In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant # has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name # (e.g. PTHREAD_CREATE_UNDETACHED on AIX). # # Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the # PTHREAD_PRIO_INHERIT symbol is defined when compiling with # PTHREAD_CFLAGS. # # ACTION-IF-FOUND is a list of shell commands to run if a threads library # is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it # is not found. If ACTION-IF-FOUND is not specified, the default action # will define HAVE_PTHREAD. # # Please let the authors know if this macro fails on any platform, or if # you have any other suggestions or comments. This macro was based on work # by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help # from M. Frigo), as well as ac_pthread and hb_pthread macros posted by # Alejandro Forero Cuervo to the autoconf macro repository. We are also # grateful for the helpful feedback of numerous users. # # Updated for Autoconf 2.68 by Daniel Richard G. # # LICENSE # # Copyright (c) 2008 Steven G.
