NAME File::ShareDir::ProjectDistDir - Simple set-and-forget using of a '/share' directory in your projects root VERSION version 0.4.3 SYNOPSIS package An::Example::Package; use File::ShareDir::ProjectDistDir; # during development, $dir will be $projectroot/share # but once installed, it will be wherever File::Sharedir thinks it is. my $dir = dist_dir('An-Example') Project layout requirements: $project/ $project/lib/An/Example/Package.pm $project/share/ # files for package 'An-Example' go here. You can use a directory name other than 'share' ( Assuming you make sure when you install that, you specify the different directory there also ) as follows: use File::ShareDir::ProjectDistDir ':all', defaults => { projectdir => 'templates', }; METHODS import use File::ShareDir::ProjectDistDir (@args); This uses "Sub::Exporter" to do the heavy lifting, so most usage of this module can be maximised by understanding that first. * ":all" ->import( ':all' , .... ) Import both "dist_dir" and "dist_file" * "dist_dir" ->import('dist_dir' , .... ) Import the dist_dir method * "dist_dir" ->import('dist_file' , .... ) Import the dist_file method * "projectdir" ->import( .... , projectdir => 'share' ) Specify what the project directory is as a path relative to the base of your distributions source, and this directory will be used as a "ShareDir" simulation path for the exported methods *During development*. If not specified, the default value 'share' is used. * "filename" ->import( .... , filename => 'some/path/to/foo.pm' ); Generally you don't want to set this, as its worked out by caller() to work out the name of the file its being called from. This file's path is walked up to find the 'lib' element with a sibling of the name of your "projectdir". * "distname" ->import( .... , distname => 'somedistname' ); Specifying this argument changes the way the functions are emitted at *installed "runtime"*, so that instead of taking the standard arguments File::ShareDir does, the specification of the "distname" in those functions is eliminated. i.e: # without this flag use File::ShareDir::ProjectDistDir qw( :all ); my $dir = dist_dir('example'); my $file = dist_file('example', 'path/to/file.pm' ); # with this flag use File::ShareDir::ProjectDistDir ( qw( :all ), distname => 'example' ); my $dir = dist_dir(); my $file = dist_file('path/to/file.pm' ); * "defaults" ->import( ... , defaults => { filename => ...., projectdir => ...., }); This is mostly an alternative syntax for specifying "filename" and "projectdir", which is mostly used internally, and their corresponding other values are packed into this one. Sub::Exporter tricks of note. Make your own sharedir util package Foo::Util; sub import { my ($caller_class, $caller_file, $caller_line ) = caller(); if ( grep { /share/ } @_ ) { require File::ShareDir::ProjectDistDir; File::ShareDir::ProjectDistDir->import( filename => $caller_file, dist_dir => { distname => 'myproject' , -as => 'share' }, dist_dir => { distname => 'otherproject' , -as => 'other_share' , projectdir => 'share2' }, -into => $caller_class, ); } } .... package Foo; use Foo::Util qw( share ); my $dir = share(); my $other_dir => other_share(); build_dist_dir use File::ShareDir::ProjectDirDir ( : all ); # this calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_dir( 'dist_dir' => {}, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } } ); use File::ShareDir::ProjectDirDir ( qw( :all ), distname => 'example-dist' ); # this calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_dir( 'dist_dir' => {}, { distname => 'example-dist', defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } } ); use File::ShareDir::ProjectDirDir dist_dir => { distname => 'example-dist', -as => 'mydistdir' }, dist_dir => { distname => 'other-dist', -as => 'otherdistdir' }; # This calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_dir( 'dist_dir', { distname => 'example-dist' }, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } }, ); my $othercoderef = File::ShareDir::ProjectDistDir->build_dist_dir( 'dist_dir', { distname => 'other-dist' }, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } }, ); # And leverages Sub::Exporter to create 2 subs in your package. Generates the exported 'dist_dir' method. In development environments, the generated method will return a path to the development directories 'share' directory. In non-development environments, this simply returns "File::ShareDir::dist_dir". As a result of this, specifying the Distribution name is not required during development, however, it will start to matter once it is installed. This is a potential avenues for bugs if you happen to name it wrong. build_dist_file use File::ShareDir::ProjectDirDir ( : all ); # this calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_file( 'dist_file' => {}, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } } ); use File::ShareDir::ProjectDirDir ( qw( :all ), distname => 'example-dist' ); # this calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_file( 'dist_file' => {}, { distname => 'example-dist', defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } } ); use File::ShareDir::ProjectDirDir dist_file => { distname => 'example-dist', -as => 'mydistfile' }, dist_file => { distname => 'other-dist', -as => 'otherdistfile' }; # This calls my $coderef = File::ShareDir::ProjectDistDir->build_dist_file( 'dist_file', { distname => 'example-dist' }, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } }, ); my $othercoderef = File::ShareDir::ProjectDistDir->build_dist_file( 'dist_file', { distname => 'other-dist' }, { defaults => { filename => 'path/to/yourcallingfile.pm', projectdir => 'share' } }, ); # And leverages Sub::Exporter to create 2 subs in your package. Generates the 'dist_file' method. In development environments, the generated method will return a path to the development directories 'share' directory. In non-development environments, this simply returns "File::ShareDir::dist_file". Caveats as a result of package-name as stated in "build_dist_dir" also apply to this method.
