App::Packager(3pm)

NAME
App::Packager - Abstraction for Packagers

SYNOPSIS
App::Packager provides an abstract interface to a number of common packagers, trying to catch as much common behaviour as possible.

The main purpose is to have uniform access to application specific resources.

Supported packagers are PAR::Packer, Cava::Packager and unpackaged. In the latter case, resources are looked up in @PATH, and the name of the application package must be passed to the first "use" of App::Packager.

For example:

    use App::Packager qw(:name My::App);
    print "My packager is: ", App::Packager::Packager(), "\n";
    print getresource("README.txt");

EXPORT
By default, function "getresource" is exported. It can be exported under a different name by providing an alternative name as follows:

    use App::Packager( ':rsc' => '...alternative name...' );

FUNCTIONS

  App::Packager::Packager
Returns the name of the actual packager, or "App Packager" if unpackaged.

  App::Packager::Version
Returns the version of the packager.

  App::Packager::IsPackaged
Returns true if the application was packaged.

Note that it is usually easier, and safer, to use $App::Packager::PACKAGED for testing since that will work even if App::Packager is not available.

App::Packager::GetResourcePath
Returns the path name of the application resources directory.

App::Packager::GetResource($rsc)
Returns the file name of the application resource.

App::Packager::GetUserFile($rsc)
Returns the file name of the user specific resource.
