NAME

6       File::ShareDir::PAR - File::ShareDir with PAR support
7

SYNOPSIS

9         use File::SharedDir::PAR ':ALL';
10         # exact same interface as the normal File::ShareDir:
11
12         # Where are distribution-level shared data files kept
13         $dir = dist_dir('File-ShareDir');
14
15         # Where are module-level shared data files kept
16         $dir = module_dir('File::ShareDir');
17
18         # Find a specific file in our dist/module shared dir
19         $file = dist_file(  'File-ShareDir',  'file/name.txt');
20         $file = module_file('File::ShareDir', 'file/name.txt');
21
22         # Like module_file, but search up the inheritance tree
23         $file = class_file( 'Foo::Bar', 'file/name.txt' );
24
25       You may choose to install the "File::ShareDir::PAR" functions into
26       "File::ShareDir" so that they become available globally. In that case,
27       you must do the following before anybody can import functions from
28       "File::ShareDir":
29
30         use File::ShareDir::PAR 'global';
31

WARNING

33       This module contains highly experimental code. If you want to load
34       modules from ".par" files using PAR and then access their shared
35       directory using "File::ShareDir", you probably have no choice but to
36       use it. But beware, here be dragons.

DESCRIPTION

39       "File::ShareDir::PAR" provides the same functionality as File::ShareDir
40       but tries hard to be compatible with PAR packaged applications.
41
42       The problem is, that the concept of having a distribution or module
43       specific share directory becomes a little hazy when you're loading
44       everything from a single file.  PAR uses an @INC hook to intercept any
45       attempt to load a module. File::ShareDir uses the directory structure
46       that is typically found in the directories that are listed in @INC for
47       storing the shared data. In a "PAR" enviroment, this is not necessarily
48       possible.
49
50       When you call one of the functions that this module provides, it will
51       take care to search in any of the currently loaded ".par" files before
52       scanning @INC. This is the same order of preference you get for loading
53       modules when PAR is in effect. If the path or file you are asking for
54       is found in one of the loaded ".par" files, that containing ".par" file
55       is extracted and the path returned will point to the extracted copy on
56       disk.
57
58       Depending on how you're using PAR, the files that are extracted this
59       way are either cleaned up after program termination or cached for
60       further executions. Either way, you're safe if you use the shared data
61       as read-only data. If you write to it, your changes may be lost after
62       the program ends.
63
64       For any further usage information, including the list of exportable
65       functions, please refer to the documentation of File::ShareDir.
