NAME File::ShareDir::Dist - Locate per-dist shared files VERSION version 0.04 SYNOPSIS use File::ShareDir::Dist qw( dist_share ); my $dir = dist_share 'Foo-Bar-Baz'; DESCRIPTION File::ShareDir::Dist finds share directories for distributions. It is similar to File::ShareDir with a few differences: Only supports distribution directories. It doesn't support perl modules or perl class directories. I have never really needed anything other than a per-dist share directory. Doesn't compute filenames. Doesn't compute files in the share directory for you. This is what File::Spec or Path::Tiny are for. Doesn't support old style shares. For some reason there are two types. I have never seen or needed the older type. Hopefully doesn't find the wrong directory. It doesn't blindly go finding the first share directory in @INC that matches the dist name. It actually checks to see that it matches the .pm file that goes along with it. That does mean that you need to have a .pm that corresponds to your dist name. This is not always the case for some older historical distributions, but it has been the recommended convetion for quite some time. No non-core dependencies. File::ShareDir only has Class::Inspector, but since we are only doing per-dist share directories we don't even need that. The goal of this project is to have no non-core dependencies for the two most recent production versions of Perl. As of this writing that means Perl 5.26 and 5.24. In the future, we may add dependencies on modules that are not part of the Perl core on older Perls. Works in your development tree. Uses the huristic, for determining if you are in a development tree, and if so, uses the common convention to find the directory named share. If you are using a relative path in @INC, if the directory share is a sibling of that relative entry in @INC and if the last element in that relative path is lib. Example, if you have the directory structure: lib/Foo/Bar/Baz.pm share/data and you invoke perl with % perl -Ilib -MFoo::Bar::Baz -MFile::ShareDir::Dist=dist_share -E 'say dist_share("Foo-Bar-Baz")' dist_share will return the (absolute) path to ./share/data. If you invoked it with: % export PERL5LIB `pwd`/lib perl -MFoo::Bar::Baz -MFile::ShareDir::Dist=dist_share -E 'say dist_share("Foo-Bar-Baz")' it would not. For me this covers most of my needs when developing a Perl module with a share directory. prove foils this huristic by making @INC absolute paths. To get around that you can use App::Prove::Plugin::ShareDirDist. Built in override. The hash %File::ShareDir::Dist::over can be used to override what dist_share returns. You can also override behavior on the command line using a dash followed by a key value pair joined by the equal sign. In other words: % perl -MFile::ShareDir::Dist=-Foo-Bar-Baz=./share -E 'say File::ShareDir::Dist::dist_share("Foo-Bar-Baz")' /.../share If neither of those work then you can set PERL_FILE_SHAREDIR_DIST to a dist name, directory pair % env PERL_FILE_SHAREDIR_DIST=Foo-Bar-Baz=`pwd`/share perl -MFile::ShareDir::Dist -E 'say File::ShareDir::Dist::dist_share("Foo-Bar-Baz")' For File::ShareDir you have to either mock the dist_dir function or install File::ShareDir::Override. For testing you can use Test::File::ShareDir. I have never understood why such a simple concept needs three modules to do all of this. FUNCTIONS Functions must be explicitly exported. They are not exported by default. dist_share my $dir = dist_share $dist_name; my $dir = dist_share $module_name; Returns the absolute path to the share directory of the given distribution. As a convenience you can also use the "main" module name assoicated with the distribution. That means if you want the share directory for thet dist Foo-Bar-Baz you may use either Foo-Bar-Baz or Foo::Bar::Baz to find it. Returns nothing if no share directory could be found. ENVIRONMENT PERL_FILE_SHAREDIR_DIST Can be used to set a single dist directory override. CAVEATS All the stuff that is in File::ShareDir but not in this module could be considered either caveats or features depending on your perspective I suppose.
