This version adds the ability to read structured data from POD sections, as well as insert arbitrary hooks into the extraction of data.

=cut =head1 DESCRIPTION This module allows you to specify those constants that should be documented in your POD, and pull them out a run time in a fairly arbitrary fashion. Pod::Constants uses Pod::Parser to do the parsing of the source file. It has to open the source file it is called from, and does so directly either by lookup in %INC or by assuming it is $0 if the caller is "main" (or it can't find %INC{caller()}) =head2 ARBITARY DECISIONS I have made this code only allow the "Pod Section Name" to match `headN', `item', `for' and `begin' POD sections. If you have a good reason why you think it should match other POD sections, drop me a line and if I'm convinced I'll put it in the standard version. For `for' and `begin' sections, only the first word is counted as being a part of the specifier, as opposed to `headN' and `item', where the entire rest of the line counts. =head1 FUNCTIONS =head2 import(@args) This function is called when we are "use"'d. It determines the source file by inspecting the value of caller() or $0. The form of @args is HOOK => $where. $where may be a scalar reference, in which case the contents of the POD section called "HOOK" will be loaded into $where. $where may be an array reference, in which case the contents of the array will be the contents of the POD section called "HOOK", split into lines. $where may be a hash reference, in which case any lines with a "=>" symbol present will have everything on the left have side of the => operator as keys and everything on the right as values. You do not need to quote either, nor have trailing commas at the end of the lines. $where may be a code reference (sub { }), in which case the sub is called when the hook is encountered. $_ is set to the value of the POD paragraph. You may also specify the behaviour of whitespace trimming; by default, no trimming is done except on the HOOK names. Setting "-trim => 1" turns on a package "global" (until the next time import is called) that will trim the $_ sent for processing by the hook processing function (be it a given function, or the built-in array/hash splitters) for leading and trailing whitespace. The name of HOOK is matched against any "=head1", "=head2", "=item", "=for", "=begin" value. If you specify the special hooknames "*item", "*head1", etc, then you will get a function that is run for every Note that the supplied functions for array and hash splitting are exactly equivalent to fairly simple Perl blocks: Array: HOOK => sub { @array = split /\n/, $_ } Hash: HOOK => sub { %hash = (map { map { s/^\s+|\s+$//g; $_ } split /=>/, $_ } (grep m/^ ( (?:[^=]|=[^>])+ ) # scan up to "=>" => ( (?:[^=]|=[^>])+ =? )# don't allow more "=>"'s $/x, split /\n/, $_)); } Well, they're simple if you can grok map, a regular expression like that and a functional programming style. If you can't I'm sure it is probably voodoo to you. Here's the procedural equivalent: HOOK => sub { for my $line (split /\n/, $_) { my ($key, $value, $junk) = split /=>/, $line; next if $junk; $key =~ s/^\s+|\s+$//g $value =~ s/^\s+|\s+$//g $hash{$key} = $value; } }, =head2 import_from_file($filename, @args) Very similar to straight "import", but you specify the source filename explicitly. =head2 add_hook(NAME => value) This function adds another hook, it is useful for dynamic updating of parsing through the document. For an example, please see t/01-constants.t in the source distribution. More detailed examples will be added in a later release. =head2 delete_hook(@list) Deletes the named hooks. Companion function to add_hook =head2 CLOSURES AS DESTINATIONS If the given value is a ref CODE, then that function is called, with $_ set to the value of the paragraph. This can be very useful for applying your own custom mutations to the POD to change it from human readable text into something your program can use. After I added this function, I just kept on thinking of cool uses for it. The nice, succinct code you can make with it is one of Pod::Constant's strongest features. Below are some examples. =head1 EXAMPLES =head2 Module Makefile.PL maintenance Tired of keeping those module Makefile.PL's up to date? Note: This method seems to break dh-make-perl. =head2 Example Makefile.PL eval "use Pod::Constants"; ($Pod::Constants::VERSION >= 0.11) or die < sub { ($VERSION) = m/(\d+\.\d+)/ }, 'DEPENDENCIES' => ($PREREQ_PM = { }), -trim => 1, 'NAME' => sub { $ABSTRACT=$_; ($NAME) = m/(\S+)/ }, 'AUTHOR' => \$AUTHOR, ); WriteMakefile ( 'NAME' => $NAME, 'PREREQ_PM' => $PREREQ_PM, 'VERSION' => $VERSION, ($] >= 5.005 ? ## Add these new keywords supported since 5.005 (ABSTRACT => $ABSTRACT, AUTHOR => $AUTHOR) : ()), ); =head2 Corresponding Module =head1 NAME MyTestModule - Demonstrate Pod::Constant's Makefile.PL usefulness =head2 MODULE RELEASE This is release 1.05 of this module. =head2 DEPENDENCIES The following modules are required to make this module: Some::Module => 0.02 =head2 AUTHOR Ima Twat =cut our $VERSION; use Pod::Constants -trim => 1, 'MODULE RELEASE' => sub { ($VERSION) = m/(\d+\.\d+) or die }; =head1 AUTHOR Sam Vilain, Maintained by Marius Gavrilescu, since July 2015 =head1 COPYRIGHT AND LICENSE Copyright (C) 2001, 2002, 2007 Sam Vilain.

But I'm not too sure how it would be all that useful in practice; you'd end up putting the function names for callbacks in the pod or something (perhaps not all that bad). Would this be useful? Pod::Constants::import(Foo::SECTION => \$myvar); Debug output is not very readable =cut
