19 use File::ShareDir ':ALL';
20
21 # Where are distribution-level shared data files kept
22 $dir = dist_dir('File-ShareDir');
23
24 # Where are module-level shared data files kept
25 $dir = module_dir('File::ShareDir');
26
27 # Find a specific file in our dist/module shared dir
28 $file = dist_file( 'File-ShareDir', 'file/name.txt');
29 $file = module_file('File::ShareDir', 'file/name.txt');
30
31 # Like module_file, but search up the inheritance tree
32 $file = class_file( 'Foo::Bar', 'file/name.txt' );
33
34=head1 DESCRIPTION
35
36The intent of L<File::ShareDir> is to provide a companion to
37L<Class::Inspector> and L<File::HomeDir>, modules that take a
38process that is well-known by advanced Perl developers but gets a
39little tricky, and make it more available to the larger Perl community.
40
41Quite often you want or need your Perl module (CPAN or otherwise)
42to have access to a large amount of read-only data that is stored
43on the file-system at run-time.
44
45On a linux-like system, this would be in a place such as /usr/share,
46however Perl runs on a wide variety of different systems, and so
47the use of any one location is unreliable.
48
49Perl provides a little-known method for doing this, but almost
50nobody is aware that it exists. As a result, module authors often
51go through some very strange ways to make the data available to
52their code.
53
54The most common of these is to dump the data out to an enormous
55Perl data structure and save it into the module itself. The
56result are enormous multi-megabyte .pm files that chew up a
57lot of memory needlessly.
58
59Another method is to put the data "file" after the __DATA__ compiler
60tag and limit yourself to access as a filehandle.
61
62The problem to solve is really quite simple.
63
64 1. Write the data files to the system at install time.
65
66 2. Know where you put them at run-time.
67
68Perl's install system creates an "auto" directory for both
69every distribution and for every module file.
70
71These are used by a couple of different auto-loading systems
72to store code fragments generated at install time, and various
73other modules written by the Perl "ancient masters".
74
75But the same mechanism is available to any dist or module to
76store any sort of data.
77
78=head2 Using Data in your Module
79
80C<File::ShareDir> forms one half of a two part solution.
81
82Once the files have been installed to the correct directory,
83you can use C<File::ShareDir> to find your files again after
84the installation.
85
86For the installation half of the solution, see L<File::ShareDir::Install>
87and its C<install_share> directive.
88
89Using L<File::ShareDir::Install> together with L<File::ShareDir>
90allows one to rely on the files in appropriate C<dist_dir()>
91or C<module_dir()> in development phase, too.
92
93=head1 FUNCTIONS
94
95C<File::ShareDir> provides four functions for locating files and
96directories.
97
98For greater maintainability, none of these are exported by default
99and you are expected to name the ones you want at use-time, or provide
100the C<':ALL'> tag. All of the following are equivalent.
101
102 # Load but don't import, and then call directly
103 use File::ShareDir;
104 $dir = File::ShareDir::dist_dir('My-Dist');
105
106 # Import a single function
107 use File::ShareDir 'dist_dir';
108 dist_dir('My-Dist');
109
110 # Import all the functions
111 use File::ShareDir ':ALL';
112 dist_dir('My-Dist');
113
114All of the functions will check for you that the dir/file actually
115exists, and that you have read permissions, or they will throw an
116exception.

538=head2 Overriding Directory Resolution
539
540C<File::ShareDir> has two convenience hashes for people who have advanced usage
541requirements of C<File::ShareDir> such as using uninstalled C<share>
542directories during development.
543
544 #
545 # Dist-Name => /absolute/path/for/DistName/share/dir
546 #
547 %File::ShareDir::DIST_SHARE
548
549 #
550 # Module::Name => /absolute/path/for/Module/Name/share/dir
551 #
552 %File::ShareDir::MODULE_SHARE
553
554Setting these values any time before the corresponding calls
555
556 dist_dir('Dist-Name')
557 dist_file('Dist-Name','some/file');
558
559 module_dir('Module::Name');
560 module_file('Module::Name','some/file');
561
562Will override the base directory for resolving those calls.
563
564An example of where this would be useful is in a test for a module that
565depends on files installed into a share directory, to enable the tests
566to use the development copy without needing to install them first.
567
568 use File::ShareDir;
569 use Cwd qw( getcwd );
570 use File::Spec::Functions qw( rel2abs catdir );
571
572 $File::ShareDir::MODULE_SHARE{'Foo::Module'} = rel2abs(catfile(getcwd,'share'));
573
574 use Foo::Module;
575
576 # internal calls in Foo::Module to module_file('Foo::Module','bar') now resolves to
577 # the source trees share/ directory instead of something in @INC

610
611If you have a bug report, a patch or a suggestion, please open a new
612report ticket at CPAN (but please check previous reports first in case
613your issue has already been addressed).
614
615Report tickets should contain a detailed description of the bug or
616enhancement request and at least an easily verifiable way of
617reproducing the issue or fix. Patches are always welcome, too.
618
619=head2 Where can I go for help with a concrete version?
620
621Bugs and feature requests are accepted against the latest version
