An alternate interface to Filter::Util::Call is now available. See L for more details. A I is implemented as a Perl module. The structure of the module can take one of two broadly similar formats. To distinguish between them, the first will be referred to as I and the second as I. Here is a skeleton for the I: package MyFilter ; use Filter::Util::Call ; sub import { my($type, @arguments) = @_ ; filter_add([]) ; } sub filter { my($self) = @_ ; my($status) ; $status = filter_read() ; $status ; } 1 ; and this is the equivalent skeleton for the I: package MyFilter ; use Filter::Util::Call ; sub import { my($type, @arguments) = @_ ; filter_add( sub { my($status) ; $status = filter_read() ; $status ; } ) } 1 ; To make use of either of the two filter modules above, place the line below in a Perl source file. use MyFilter; In fact, the skeleton modules shown above are fully functional I, albeit fairly useless ones. All they does is filter the source stream without modifying it at all. As you can see both modules have a broadly similar structure. They both make use of the C module and both have an C method. The difference between them is that the I requires a I method, whereas the I gets the equivalent of a I method with the anonymous sub passed to I. To make proper use of the I shown above you need to have a good understanding of the concept of a I. See L for more details on the mechanics of I. =head2 B The following functions are exported by C: filter_add() filter_read() filter_read_exact() filter_del() =head2 B The C method is used to create an instance of the filter. It is called indirectly by Perl when it encounters the C line in a source file (See L for more details on C). It will always have at least one parameter automatically passed by Perl - this corresponds to the name of the package. In the example above it will be C<"MyFilter">. Apart from the first parameter, import can accept an optional list of parameters. These can be used to pass parameters to the filter. For example: use MyFilter qw(a b c) ; will result in the C<@_> array having the following values: @_ [0] => "MyFilter" @_ [1] => "a" @_ [2] => "b" @_ [3] => "c" Before terminating, the C function must explicitly install the filter by calling C. =head2 B The function, C, actually installs the filter. It takes one parameter which should be a reference. The kind of reference used will dictate which of the two filter types will be used. If a CODE reference is used then a I will be assumed. If a CODE reference is not used, a I will be assumed. In a I, the reference can be used to store context information. The reference will be I into the package by C, unless the reference was already blessed. See the filters at the end of this documents for examples of using context information using both I and I. =head2 B Both the C method used with a I and the anonymous sub used with a I is where the main processing for the filter is done. The big difference between the two types of filter is that the I uses the object passed to the method to store any context data, whereas the I uses the lexical variables that are maintained by the closure. Note that the single parameter passed to the I, C<$self>, is the same reference that was passed to C blessed into the filter's package. See the example filters later on for details of using C<$self>. Here is a list of the common features of the anonymous sub and the C method. =over 5 =item B<$_> Although C<$_> doesn't actually appear explicitly in the sample filters above, it is implicitly used in a number of places. Firstly, when either C or the anonymous sub are called, a local copy of C<$_> will automatically be created. It will always contain the empty string at this point. Next, both C and C will append any source data that is read to the end of C<$_>. Finally, when C or the anonymous sub are finished processing, they are expected to return the filtered source using C<$_>. This implicit use of C<$_> greatly simplifies the filter. =item B<$status> The status value that is returned by the user's C method or anonymous sub and the C and C functions take the same set of values, namely: < 0 Error = 0 EOF > 0 OK =item B and B These functions are used by the filter to obtain either a line or block from the next filter in the chain or the actual source file if there aren't any other filters. The function C takes two forms: $status = filter_read() ; $status = filter_read($size) ; The first form is used to request a I, the second requests a I. In line mode, C will append the next source line to the end of the C<$_> scalar. In block mode, C will append a block of data which is <= C<$size> to the end of the C<$_> scalar. It is important to emphasise the that C will not necessarily read a block which is I C<$size> bytes. If you need to be able to read a block which has an exact size, you can use the function C. It works identically to C in block mode, except it will try to read a block which is exactly C<$size> bytes in length. The only circumstances when it will not return a block which is C<$size> bytes long is on EOF or error. It is I important to check the value of C<$status> after I call to C or C. =item B The function, C, is used to disable the current filter. It does not affect the running of the filter. All it does is tell Perl not to call filter any more. See L for details. =item I Internal function which adds the filter, based on the L argument type. =item I May be used to disable a filter, but is rarely needed. See L. =back =head1 LIMITATIONS See L for an overview of the general problems filtering code in a textual line-level only. =over =item __DATA__ is ignored The content from the __DATA__ block is not filtered. This is a serious limitation, e.g. for the L module. See L for more. =item Max. codesize limited to 32-bit Currently internal buffer lengths are limited to 32-bit only. =back =head1 EXAMPLES Here are a few examples which illustrate the key concepts - as such most of them are of little practical use. The C sub-directory has copies of all these filters implemented both as I and as I. =head2 Example 1: A simple filter. Below is a I which is hard-wired to replace all occurrences of the string C<"Joe"> to C<"Jim">. Not particularly Useful, but it is the first example and I wanted to keep it simple. package Joe2Jim ; use Filter::Util::Call ; sub import { my($type) = @_ ; filter_add(bless []) ; } sub filter { my($self) = @_ ; my($status) ; s/Joe/Jim/g if ($status = filter_read()) > 0 ; $status ; } 1 ; Here is an example of using the filter: use Joe2Jim ; print "Where is Joe?\n" ; And this is what the script above will print: Where is Jim? =head2 Example 2: Using the context The previous example was not particularly useful. To make it more general purpose we will make use of the context data and allow any arbitrary I and I strings to be used. This time we will use a I. To reflect its enhanced role, the filter is called C. package Subst ; use Filter::Util::Call ; use Carp ; sub import { croak("usage: use Subst qw(from to)") unless @_ == 3 ; my ($self, $from, $to) = @_ ; filter_add( sub { my ($status) ; s/$from/$to/ if ($status = filter_read()) > 0 ; $status ; }) } 1 ; and is used like this: use Subst qw(Joe Jim) ; print "Where is Joe?\n" ; =head2 Example 3: Using the context within the filter Here is a filter which a variation of the C filter. As well as substituting all occurrences of C<"Joe"> to C<"Jim"> it keeps a count of the number of substitutions made in the context object. Once EOF is detected (C<$status> is zero) the filter will insert an extra line into the source stream. When this extra line is executed it will print a count of the number of substitutions actually made. Note that C<$status> is set to C<1> in this case. package Count ; use Filter::Util::Call ; sub filter { my ($self) = @_ ; my ($status) ; if (($status = filter_read()) > 0 ) { s/Joe/Jim/g ; ++ $$self ; } elsif ($$self >= 0) { # EOF $_ = "print q[Made ${$self} substitutions\n]" ; $status = 1 ; $$self = -1 ; } $status ; } sub import { my ($self) = @_ ; my ($count) = 0 ; filter_add(\$count) ; } 1 ; Here is a script which uses it: use Count ; print "Hello Joe\n" ; print "Where is Joe\n" ; Outputs: Hello Jim Where is Jim Made 2 substitutions =head2 Example 4: Using filter_del Another variation on a theme. This time we will modify the C filter to allow a starting and stopping pattern to be specified as well as the I and I patterns. If you know the I editor, it is the equivalent of this command: :/start/,/stop/s/from/to/ When used as a filter we want to invoke it like this: use NewSubst qw(start stop from to) ; Here is the module. package NewSubst ; use Filter::Util::Call ; use Carp ; sub import { my ($self, $start, $stop, $from, $to) = @_ ; my ($found) = 0 ; croak("usage: use Subst qw(start stop from to)") unless @_ == 5 ; filter_add( sub { my ($status) ; if (($status = filter_read()) > 0) { $found = 1 if $found == 0 and /$start/ ; if ($found) { s/$from/$to/ ; filter_del() if /$stop/ ; } } $status ; } ) } 1 ; =head1 Filter::Simple If you intend using the Filter::Call functionality, I would strongly recommend that you check out Damian Conway's excellent Filter::Simple module. Damian's module provides a much cleaner interface than Filter::Util::Call. Although it doesn't allow the fine control that Filter::Util::Call does, it should be adequate for the majority of applications.

This requires a working diff program to be installed on your system. =head2 --copy=I If this option is given, a copy of each file will be saved with the given suffix that contains the suggested changes. This does not require any external programs. Note that this does not automagially add a dot between the original filename and the suffix. If you want the dot, you have to include it in the option argument. If neither C<--patch> or C<--copy> are given, the default is to simply print the diffs for each file. This requires either C or a C program to be installed. =head2 --diff=I Manually set the diff program and options to use. The default is to use C, when installed, and output unified context diffs. =head2 --compat-version=I Tell F to check for compatibility with the given Perl version. The default is to check for compatibility with Perl version 5.003. You can use this option to reduce the output of F if you intend to be backward compatible only down to a certain Perl version. =head2 --cplusplus Usually, F will detect C++ style comments and replace them with C style comments for portability reasons. Using this option instructs F to leave C++ comments untouched. =head2 --quiet Be quiet. Don't print anything except fatal errors. =head2 --nodiag Don't output any diagnostic messages. Only portability alerts will be printed. =head2 --nohints Don't output any hints. Hints often contain useful portability notes. Warnings will still be displayed. =head2 --nochanges Don't suggest any changes. Only give diagnostic output and hints unless these are also deactivated. =head2 --nofilter Don't filter the list of input files. By default, files not looking like source code (i.e. not *.xs, *.c, *.cc, *.cpp or *.h) are skipped. =head2 --strip Strip all script and documentation functionality from F. This reduces the size of F dramatically and may be useful if you want to include F in smaller modules without increasing their distribution size too much. The stripped F will have a C<--unstrip> option that allows you to undo the stripping, but only if an appropriate C module is installed. =head2 --list-provided Lists the API elements for which compatibility is provided by F. Also lists if it must be explicitly requested, if it has dependencies, and if there are hints or warnings for it. =head2 --list-unsupported Lists the API elements that are known not to be supported by F and below which version of Perl they probably won't be available or work. =head2 --api-info=I Show portability information for API elements matching I. If I is surrounded by slashes, it is interpreted as a regular expression. =head1 DESCRIPTION In order for a Perl extension (XS) module to be as portable as possible across differing versions of Perl itself, certain steps need to be taken. =over 4 =item * Including this header is the first major one. This alone will give you access to a large part of the Perl API that hasn't been available in earlier Perl releases. Use perl ppport.h --list-provided to see which API elements are provided by ppport.h. =item * You should avoid using deprecated parts of the API. For example, using global Perl variables without the C prefix is deprecated. Also, some API functions used to have a C prefix. Using this form is also deprecated. You can safely use the supported API, as F will provide wrappers for older Perl versions. =item * If you use one of a few functions or variables that were not present in earlier versions of Perl, and that can't be provided using a macro, you have to explicitly request support for these functions by adding one or more C<#define>s in your source code before the inclusion of F. These functions or variables will be marked C in the list shown by C<--list-provided>. Depending on whether you module has a single or multiple files that use such functions or variables, you want either C or global variants. For a C function or variable (used only in a single source file), use: #define NEED_function #define NEED_variable For a global function or variable (used in multiple source files), use: #define NEED_function_GLOBAL #define NEED_variable_GLOBAL Note that you mustn't have more than one global request for the same function or variable in your project.

Just C<#define> the macro before including C: #define DPPP_NAMESPACE MyOwnNamespace_ #include "ppport.h" The default namespace is C. =back The good thing is that most of the above can be checked by running F on your source code. See the next section for details. =head1 EXAMPLES To verify whether F is needed for your module, whether you should make any changes to your code, and whether any special defines should be used, F can be run as a Perl script to check your source code. Simply say: perl ppport.h The result will usually be a list of patches suggesting changes that should at least be acceptable, if not necessarily the most efficient solution, or a fix for all possible problems. If you know that your XS module uses features only available in newer Perl releases, if you're aware that it uses C++ comments, and if you want all suggestions as a single patch file, you could use something like this: perl ppport.h --compat-version=5.6.0 --cplusplus --patch=test.diff If you only want your code to be scanned without any suggestions for changes, use: perl ppport.h --nochanges You can specify a different C program or options, using the C<--diff> option: perl ppport.h --diff='diff -C 10' This would output context diffs with 10 lines of context. If you want to create patched copies of your files instead, use: perl ppport.h --copy=.new To display portability information for the C function, use: perl ppport.h --api-info=newSVpvn Since the argument to C<--api-info> can be a regular expression, you can use perl ppport.h --api-info=/_nomg$/ to display portability information for all C<_nomg> functions or perl ppport.h --api-info=/./ to display information for all known API elements. =head1 BUGS If this version of F is causing failure during the compilation of this module, please check if newer versions of either this module or C are available on CPAN before sending a bug report.

Source filters alter the program text of a module before Perl sees it, much as a C preprocessor alters the source text of a C program before the compiler sees it. This article tells you more about what source filters are, how they work, and how to write your own. The original purpose of source filters was to let you encrypt your program source to prevent casual piracy. This isn't all they can do, as you'll soon learn. But first, the basics. =head1 CONCEPTS Before the Perl interpreter can execute a Perl script, it must first read it from a file into memory for parsing and compilation. If that script itself includes other scripts with a C or C statement, then each of those scripts will have to be read from their respective files as well. Now think of each logical connection between the Perl parser and an individual file as a I. A source stream is created when the Perl parser opens a file, it continues to exist as the source code is read into memory, and it is destroyed when Perl is finished parsing the file. If the parser encounters a C or C statement in a source stream, a new and distinct stream is created just for that file. The diagram below represents a single source stream, with the flow of source from a Perl script file on the left into the Perl parser on the right. This is how Perl normally operates. file -------> parser There are two important points to remember: =over 5 =item 1. Although there can be any number of source streams in existence at any given time, only one will be active. =item 2. Every source stream is associated with only one file. =back A source filter is a special kind of Perl module that intercepts and modifies a source stream before it reaches the parser. A source filter changes our diagram like this: file ----> filter ----> parser If that doesn't make much sense, consider the analogy of a command pipeline. Say you have a shell script stored in the compressed file I. The simple pipeline command below runs the script without needing to create a temporary file to hold the uncompressed file. gunzip -c trial.gz | sh In this case, the data flow from the pipeline can be represented as follows: trial.gz ----> gunzip ----> sh With source filters, you can store the text of your script compressed and use a source filter to uncompress it for Perl's parser: compressed gunzip Perl program ---> source filter ---> parser =head1 USING FILTERS So how do you use a source filter in a Perl script? Above, I said that a source filter is just a special kind of module. Like all Perl modules, a source filter is invoked with a use statement. Say you want to pass your Perl source through the C preprocessor before execution. As it happens, the source filters distribution comes with a C preprocessor filter module called Filter::cpp. Below is an example program, C, which makes use of this filter. Line numbers have been added to allow specific lines to be referenced easily. 1: use Filter::cpp; 2: #define TRUE 1 3: $a = TRUE; 4: print "a = $a\n"; When you execute this script, Perl creates a source stream for the file. Before the parser processes any of the lines from the file, the source stream looks like this: cpp_test ---------> parser Line 1, C, includes and installs the C filter module. All source filters work this way. The use statement is compiled and executed at compile time, before any more of the file is read, and it attaches the cpp filter to the source stream behind the scenes. Now the data flow looks like this: cpp_test ----> cpp filter ----> parser As the parser reads the second and subsequent lines from the source stream, it feeds those lines through the C source filter before processing them. The C filter simply passes each line through the real C preprocessor. The output from the C preprocessor is then inserted back into the source stream by the filter. .-> cpp --. | | | | | <-' cpp_test ----> cpp filter ----> parser The parser then sees the following code: use Filter::cpp; $a = 1; print "a = $a\n"; Let's consider what happens when the filtered code includes another module with use: 1: use Filter::cpp; 2: #define TRUE 1 3: use Fred; 4: $a = TRUE; 5: print "a = $a\n"; The C filter does not apply to the text of the Fred module, only to the text of the file that used it (C). Although the use statement on line 3 will pass through the cpp filter, the module that gets included (C) will not. The source streams look like this after line 3 has been parsed and before line 4 is parsed: cpp_test ---> cpp filter ---> parser (INACTIVE) Fred.pm ----> parser As you can see, a new stream has been created for reading the source from C. This stream will remain active until all of C has been parsed. The source stream for C will still exist, but is inactive. Once the parser has finished reading Fred.pm, the source stream associated with it will be destroyed. The source stream for C then becomes active again and the parser reads line 4 and subsequent lines from C. You can use more than one source filter on a single file. Similarly, you can reuse the same filter in as many files as you like. For example, if you have a uuencoded and compressed source file, it is possible to stack a uudecode filter and an uncompression filter like this: use Filter::uudecode; use Filter::uncompress; M'XL(".H7/;1I;_>_I3=&E=%:F*I"T?22Q/ M6]9* ... Once the first line has been processed, the flow will look like this: file ---> uudecode ---> uncompress ---> parser filter filter Data flows through filters in the same order they appear in the source file. The uudecode filter appeared before the uncompress filter, so the source file will be uudecoded before it's uncompressed. =head1 WRITING A SOURCE FILTER There are three ways to write your own source filter. You can write it in C, use an external program as a filter, or write the filter in Perl. I won't cover the first two in any great detail, so I'll get them out of the way first. Writing the filter in Perl is most convenient, so I'll devote the most space to it. =head1 WRITING A SOURCE FILTER IN C The first of the three available techniques is to write the filter completely in C. The external module you create interfaces directly with the source filter hooks provided by Perl. The advantage of this technique is that you have complete control over the implementation of your filter. The big disadvantage is the increased complexity required to write the filter - not only do you need to understand the source filter hooks, but you also need a reasonable knowledge of Perl guts. One of the few times it is worth going to this trouble is when writing a source scrambler. The C filter (which unscrambles the source before Perl parses it) included with the source filter distribution is an example of a C source filter (see Decryption Filters, below). =over 5 =item B All decryption filters work on the principle of "security through obscurity." Regardless of how well you write a decryption filter and how strong your encryption algorithm is, anyone determined enough can retrieve the original source code. The reason is quite simple - once the decryption filter has decrypted the source back to its original form, fragments of it will be stored in the computer's memory as Perl parses it. The source might only be in memory for a short period of time, but anyone possessing a debugger, skill, and lots of patience can eventually reconstruct your program. That said, there are a number of steps that can be taken to make life difficult for the potential cracker. The most important: Write your decryption filter in C and statically link the decryption module into the Perl binary. For further tips to make life difficult for the potential cracker, see the file I in the source filters distribution. =back =head1 CREATING A SOURCE FILTER AS A SEPARATE EXECUTABLE An alternative to writing the filter in C is to create a separate executable in the language of your choice. The separate executable reads from standard input, does whatever processing is necessary, and writes the filtered data to standard output. C is an example of a source filter implemented as a separate executable - the executable is the C preprocessor bundled with your C compiler. The source filter distribution includes two modules that simplify this task: C and C. Both allow you to run any external executable. Both use a coprocess to control the flow of data into and out of the external executable. (For details on coprocesses, see Stephens, W.R., "Advanced Programming in the UNIX Environment." Addison-Wesley, ISBN 0-210-56317-7, pages 441-445.) The difference between them is that C spawns the external command directly, while C spawns a shell to execute the external command. (Unix uses the Bourne shell; NT uses the cmd shell.) Spawning a shell allows you to make use of the shell metacharacters and redirection facilities. Here is an example script that uses C: use Filter::sh 'tr XYZ PQR'; $a = 1; print "XYZ a = $a\n"; The output you'll get when the script is executed: PQR a = 1 Writing a source filter as a separate executable works fine, but a small performance penalty is incurred. For example, if you execute the small example above, a separate subprocess will be created to run the Unix C command. Each use of the filter requires its own subprocess. If creating subprocesses is expensive on your system, you might want to consider one of the other options for creating source filters. =head1 WRITING A SOURCE FILTER IN PERL The easiest and most portable option available for creating your own source filter is to write it completely in Perl. To distinguish this from the previous two techniques, I'll call it a Perl source filter. To help understand how to write a Perl source filter we need an example to study. Here is a complete source filter that performs rot13 decoding. (Rot13 is a very simple encryption scheme used in Usenet postings to hide the contents of offensive posts. It moves every letter forward thirteen places, so that A becomes N, B becomes O, and Z becomes M.) package Rot13; use Filter::Util::Call; sub import { my ($type) = @_; my ($ref) = []; filter_add(bless $ref); } sub filter { my ($self) = @_; my ($status); tr/n-za-mN-ZA-M/a-zA-Z/ if ($status = filter_read()) > 0; $status; } 1; =for apidoc filter_add =for apidoc filter_read All Perl source filters are implemented as Perl classes and have the same basic structure as the example above. First, we include the C module, which exports a number of functions into your filter's namespace. The filter shown above uses two of these functions, C and C. Next, we create the filter object and associate it with the source stream by defining the C function. If you know Perl well enough, you know that C is called automatically every time a module is included with a use statement. This makes C the ideal place to both create and install a filter object. In the example filter, the object (C<$ref>) is blessed just like any other Perl object. Our example uses an anonymous array, but this isn't a requirement. Because this example doesn't need to store any context information, we could have used a scalar or hash reference just as well. The next section demonstrates context data. The association between the filter object and the source stream is made with the C function. This takes a filter object as a parameter (C<$ref> in this case) and installs it in the source stream. Finally, there is the code that actually does the filtering. For this type of Perl source filter, all the filtering is done in a method called C. (It is also possible to write a Perl source filter using a closure. See the L manual page for more details.) It's called every time the Perl parser needs another line of source to process. The C method, in turn, reads lines from the source stream using the C function. If a line was available from the source stream, C returns a status value greater than zero and appends the line to C<$_>. A status value of zero indicates end-of-file, less than zero means an error. The filter function itself is expected to return its status in the same way, and put the filtered line it wants written to the source stream in C<$_>. The use of C<$_> accounts for the brevity of most Perl source filters. In order to make use of the rot13 filter we need some way of encoding the source file in rot13 format. The script below, C, does just that. die "usage mkrot13 filename\n" unless @ARGV; my $in = $ARGV[0]; my $out = "$in.tmp"; open(IN, "<$in") or die "Cannot open file $in: $!\n"; open(OUT, ">$out") or die "Cannot open file $out: $!\n"; print OUT "use Rot13;\n"; while () { tr/a-zA-Z/n-za-mN-ZA-M/; print OUT; } close IN; close OUT; unlink $in; rename $out, $in; If we encrypt this with C: print " hello fred \n"; the result will be this: use Rot13; cevag "uryyb serq\a"; Running it produces this output: hello fred =head1 USING CONTEXT: THE DEBUG FILTER The rot13 example was a trivial example. Here's another demonstration that shows off a few more features. Say you wanted to include a lot of debugging code in your Perl script during development, but you didn't want it available in the released product. Source filters offer a solution. In order to keep the example simple, let's say you wanted the debugging output to be controlled by an environment variable, C. Debugging code is enabled if the variable exists, otherwise it is disabled. Two special marker lines will bracket debugging code, like this: ## DEBUG_BEGIN if ($year > 1999) { warn "Debug: millennium bug in year $year\n"; } ## DEBUG_END The filter ensures that Perl parses the code between the and C markers only when the C environment variable exists. That means that when C does exist, the code above should be passed through the filter unchanged. The marker lines can also be passed through as-is, because the Perl parser will see them as comment lines. When C isn't set, we need a way to disable the debug code. A simple way to achieve that is to convert the lines between the two markers into comments: ## DEBUG_BEGIN #if ($year > 1999) { # warn "Debug: millennium bug in year $year\n"; #} ## DEBUG_END Here is the complete Debug filter: package Debug; use strict; use warnings; use Filter::Util::Call; use constant TRUE => 1; use constant FALSE => 0; sub import { my ($type) = @_; my (%context) = ( Enabled => defined $ENV{DEBUG}, InTraceBlock => FALSE, Filename => (caller)[1], LineNo => 0, LastBegin => 0, ); filter_add(bless \%context); } sub Die { my ($self) = shift; my ($message) = shift; my ($line_no) = shift || $self->{LastBegin}; die "$message at $self->{Filename} line $line_no.\n" } sub filter { my ($self) = @_; my ($status); $status = filter_read(); ++ $self->{LineNo}; # deal with EOF/error first if ($status <= 0) { $self->Die("DEBUG_BEGIN has no DEBUG_END") if $self->{InTraceBlock}; return $status; } if ($self->{InTraceBlock}) { if (/^\s*##\s*DEBUG_BEGIN/ ) { $self->Die("Nested DEBUG_BEGIN", $self->{LineNo}) } elsif (/^\s*##\s*DEBUG_END/) { $self->{InTraceBlock} = FALSE; } # comment out the debug lines when the filter is disabled s/^/#/ if ! $self->{Enabled}; } elsif ( /^\s*##\s*DEBUG_BEGIN/ ) { $self->{InTraceBlock} = TRUE; $self->{LastBegin} = $self->{LineNo}; } elsif ( /^\s*##\s*DEBUG_END/ ) { $self->Die("DEBUG_END has no DEBUG_BEGIN", $self->{LineNo}); } return $status; } 1; The big difference between this filter and the previous example is the use of context data in the filter object. The filter object is based on a hash reference, and is used to keep various pieces of context information between calls to the filter function. All but two of the hash fields are used for error reporting. The first of those two, Enabled, is used by the filter to determine whether the debugging code should be given to the Perl parser. The second, InTraceBlock, is true when the filter has encountered a C line, but has not yet encountered the following C line. If you ignore all the error checking that most of the code does, the essence of the filter is as follows: sub filter { my ($self) = @_; my ($status); $status = filter_read(); # deal with EOF/error first return $status if $status <= 0; if ($self->{InTraceBlock}) { if (/^\s*##\s*DEBUG_END/) { $self->{InTraceBlock} = FALSE } # comment out debug lines when the filter is disabled s/^/#/ if ! $self->{Enabled}; } elsif ( /^\s*##\s*DEBUG_BEGIN/ ) { $self->{InTraceBlock} = TRUE; } return $status; } Be warned: just as the C-preprocessor doesn't know C, the Debug filter doesn't know Perl. It can be fooled quite easily: print < environment variable can then be used to control which blocks get included. Once you can identify individual blocks, try allowing them to be nested. That isn't difficult either. Here is an interesting idea that doesn't involve the Debug filter. Currently Perl subroutines have fairly limited support for formal parameter lists. You can specify the number of parameters and their type, but you still have to manually take them out of the C<@_> array yourself. Write a source filter that allows you to have a named parameter list. Such a filter would turn this: sub MySub ($first, $second, @rest) { ... } into this: sub MySub($$@) { my ($first) = shift; my ($second) = shift; my (@rest) = @_; ... } Finally, if you feel like a real challenge, have a go at writing a full-blown Perl macro preprocessor as a source filter. Borrow the useful features from the C preprocessor and any other macro processors you know. The tricky bit will be choosing how much knowledge of Perl's syntax you want your filter to have. =head1 LIMITATIONS Source filters only work on the string level, thus are highly limited in its ability to change source code on the fly. It cannot detect comments, quoted strings, heredocs, it is no replacement for a real parser. The only stable usage for source filters are encryption, compression, or the byteloader, to translate binary code back to source code. See for example the limitations in L, which uses source filters, and thus is does not work inside a string eval, the presence of regexes with embedded newlines that are specified with raw C delimiters and don't have a modifier C are indistinguishable from code chunks beginning with the division operator C. As a workaround you must use C or C for such patterns. Also, the presence of regexes specified with raw C delimiters may cause mysterious errors. The workaround is to use C instead. See L. Currently the content of the C<__DATA__> block is not filtered. Currently internal buffer lengths are limited to 32-bit only. =head1 THINGS TO LOOK OUT FOR =over 5 =item Some Filters Clobber the C Handle Some source filters use the C handle to read the calling program. When using these source filters you cannot rely on this handle, nor expect any particular kind of behavior when operating on it. Filters based on Filter::Util::Call (and therefore Filter::Simple) do not alter the C filehandle, but on the other hand totally ignore the text after C<__DATA__>. =back =head1 REQUIREMENTS The Source Filters distribution is available on CPAN, in CPAN/modules/by-module/Filter Starting from Perl 5.8 Filter::Util::Call (the core part of the Source Filters distribution) is part of the standard Perl distribution.

For more details see the pod documentation embedded in the .pm files. If you intend using the Filter::Util::Call functionality, I would strongly recommend that you check out Damian Conway's excellent Filter::Simple module. Damian's module provides a much cleaner interface than Filter::Util::Call. Although it doesn't allow the fine control that Filter::Util::Call does, it should be adequate for the majority of applications. It's available at http://search.cpan.org/dist/Filter-Simple/ LIMITATIONS ----------- Source filters only work on the string level, thus are highly limited in its ability to change source code on the fly. It cannot detect comments, quoted strings, heredocs, it is no replacement for a real parser. The only stable usage for source filters are encryption, compression, or the byteloader, to translate binary code back to source code. See for example the limitations in Switch, which uses source filters, and thus is does not work inside a string eval, the presence of regexes with embedded newlines that are specified with raw /.../ delimiters and don't have a modifier //x are indistinguishable from code chunks beginning with the division operator /. As a workaround you must use m/.../ or m?...? for such patterns. Also, the presence of regexes specified with raw ?...? delimiters may cause mysterious errors. The workaround is to use m?...? instead. See http://search.cpan.org/perldoc?Switch#LIMITATIONS Currently internal buffer lengths are limited to 32-bit only. PREREQUISITES ------------- Before you can build the Source Filters you need to have the following installed on your system: * Perl 5.6.0 or better For older Perls use older versions of Filter. BUILDING THE MODULES -------------------- Assuming you have met all the prerequisites, building the modules should be relatively straightforward. The modules can now be built using this sequence of commands: perl Makefile.PL make make test The filters have been successfully built and tested on the following systems (at least): linux (gcc or clang) FreeBSD 11 - 13 cygwin 1.7 mingw strawberry SunOS 4.1.3 (Sun C compiler & gcc 2.7.2.3) Solaris 2.3 (Sun C Compiler) irix 5.3 irix 6.x Windows XP - 10 (Visual C++) On Windows tr.exe, cpp.exe, and m4.exe should be really the gnu/mingw tools in the path for the testsuite to pass successfully.

Although this is a fully functional source filter and it does implement a I simple decrypt algorithm, it is I intended to be used as it is supplied. Consider it to be a template which you can combine with a proper decryption algorithm to develop your own decryption filter. =head1 WARNING It is important to note that a decryption filter can I provide complete security against attack. At some point the parser within Perl needs to be able to scan the original decrypted source. That means that at some stage fragments of the source will exist in a memory buffer. Also, with the introduction of the Perl Compiler backend modules, and the B::Deparse module in particular, using a Source Filter to hide source code is becoming an increasingly futile exercise. The best you can hope to achieve by decrypting your Perl source using a source filter is to make it unavailable to the casual user. Given that proviso, there are a number of things you can do to make life more difficult for the prospective cracker. =over 5 =item 1. Strip the Perl binary to remove all symbols. =item 2. Build the decrypt extension using static linking. If the extension is provided as a dynamic module, there is nothing to stop someone from linking it at run time with a modified Perl binary. =item 3. Do not build Perl with C<-DDEBUGGING>. If you do then your source can be retrieved with the C<-DP> command line option. The sample filter contains logic to detect the C option. =item 4. Do not build Perl with C debugging support enabled. =item 5. Do not implement the decryption filter as a sub-process (like the cpp source filter). It is possible to peek into the pipe that connects to the sub-process. =item 6. Check that the Perl Compiler isn't being used. There is code in the BOOT: section of decrypt.xs that shows how to detect the presence of the Compiler. Make sure you include it in your module. Assuming you haven't taken any steps to spot when the compiler is in use and you have an encrypted Perl script called "myscript.pl", you can get access the source code inside it using the perl Compiler backend, like this perl -MO=Deparse myscript.pl Note that even if you have included the BOOT: test, it is still possible to use the Deparse module to get the source code for individual subroutines. =item 7. Do not use the decrypt filter as-is. The algorithm used in this filter has been purposefully left simple. =back If you feel that the source filtering mechanism is not secure enough you could try using the unexec/undump method. See the Perl FAQ for further details. =head1 AUTHOR Paul Marquess =head1 DATE 19th December 1995 =cut Filter-1.64/decrypt/decrypt.xs0000644000175000017500000001757014276777775016004 0ustar rurbanrurban/* * Filename : decrypt.xs * * Author : Reini Urban * Date : Di 16.

By default and when the filename is prefixed with a '>' the output file will be emptied first if it already exists. If the output filename is prefixed with '>>' it will be opened for appending.

=head1 DESCRIPTION This source filter pipes the current source file through the M4 macro processor (C) if it is available. As with all source filters its scope is limited to the current source file only. Every file you want to be processed by the filter must have the following line near the top. use Filter::m4; =head1 EXAMPLE Here is a small example that shows how to define and use an M4 macro: use Filter::m4; define(`foo', `$1 =~ s/bar/baz/r') $a = "foobar"; print "a = " . foo(`$a') . "\n"; The output of the above example: a = foobaz =head1 NOTES By default, M4 uses ` and ' as quotes; however, this is configurable using M4's C builtin. M4 uses C<$1>, C<$2>, etc., to indicate arguments in macros. To avoid clashes with Perl regex syntax it is recommended to use Perl's alternative forms C<${1}>, C<${1}>, etc. The following keywords in M4 and Perl are identical: eval format index mkstemp shift substr If you need such keywords in your Perl code you have to use one of the following three solutions. =over =item * Protect the keyword with M4 quotes, for example C<`shift'>. =item * Redefine the problematic M4 builtin using C, as outlined in section I of the M4 info manual. =item * Use the C option. This adds the prefix C to all M4 builtins (but not to user-defined macros). For example, you will have to use C instead of C. =back =head1 AUTHOR Werner Lemberg =head1 DATE 17th March 2018. =cut Filter-1.64/lib/Filter/exec.pm0000644000175000017500000000235014276777775015547 0ustar rurbanrurbanpackage Filter::exec ; use Filter::Util::Exec ; use strict ; use warnings ; our $VERSION = "1.64" ; sub import { my($self, @args) = @_ ; unless (@args) { require Carp; Carp::croak("Usage: use Filter::exec 'command'"); } Filter::Util::Exec::filter_add($self, @args) ; } 1 ; __END__ =head1 NAME Filter::exec - exec source filter =head1 SYNOPSIS use Filter::exec qw(command parameters) ; =head1 DESCRIPTION This filter pipes the current source file through the program which corresponds to the C parameter.
