NAME

Dist::Util::Current - Guess the current Perl distribution name

VERSION

This document describes version 0.003 of Dist::Util::Current (from Perl distribution Dist-Util-Current), released on 2022-11-07.

SYNOPSIS

 use Dist::Util::Current qw(my_dist);

 my $dist = my_dist();

DESCRIPTION

FUNCTIONS

my_dist

Usage:

 my_dist(%opts) => STR|HASH

Guess the current distribution (the Perl distribution associated with the source code) using one of several ways.

Options:

  • filename

    String. The path to source code file. If unspecified, will use file name retrieved from caller(0).

  • package

    String. The caller's package. If unspecified, will use package name retrieved from caller(0).

How the function works:

1. $DIST

If the caller's package defines a package variable $DIST, will return this.

2. .packlist for module or supermodules

Will check .packlist for module or supermodules. For example, if module is Algorithm::Backoff::Constant then will try to check for .packlist for Algorithm::Backoff::Constant, Algorithm::Backoff, and Algorithm.

For each found .packlist will read its contents and check whether the filename is listed. If yes, then we've found the distribution name and return it.

3. .packlist in @INC

Will check .packlist in directories listed in @INC. Will use Dist::Util's list_dists() for this.

For each found .packlist will read its contents and check whether the filename is listed. If yes, then we've found the distribution name and return it.

4. Try this_dist() against current directory and several levels up

Will guess using App::ThisDist's this_dist() against the current directory and several levels up.

If all of the above fails, we return undef.

TODO: Query the OS's package manager.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
