NAME

Parse::PMFile - parses .pm file as PAUSE does

SYNOPSIS

    use Parse::PMFile;
    my $parser = Parse::PMFile->new($metadata, {VERBOSE => 1});
    my $packages_info = $parser->parse($pmfile);
    # if you need info about invalid versions
    my ($packages_info, $errors) = $parser->parse($pmfile);
    # to check permissions
    my $parser = Parse::PMFile->new($metadata, {
        USERID => 'ISHIGAKI',
        PERMISSIONS => PAUSE::Permissions->new,
    });

DESCRIPTION

The most of the code of this module is taken from the PAUSE code as of April 2013 almost verbatim. Thus, the heart of this module should be quite stable. However, I made it not to use pipe ("-|") as well as I stripped database-related code. If you encounter any issue, that's most probably because of my modification.

This module doesn't provide features to extract a distribution or parse meta files intentionally.

METHODS

new

creates an object. You can also pass a hashref taken from META.yml etc, and an optional hashref. Options are:

Parse::PMFile usually ignores a version with an underscore as PAUSE does (because it's for a developer release, and should not be indexed). Set this option to true if you happen to need to keep such a version for better analysis.
Set this to true if you need to know some details.
As of version 0.17, Parse::PMFile stops forking while parsing a version for better performance. Parse::PMFile should return the same result no matter how this option is set, but if you do care, set this to true to fork as PAUSE does.
As of version 0.21, Parse::PMFile checks permissions of a package if both USERID and PERMISSIONS (which should be an instance of PAUSE::Permissions) are provided. Unauthorized packages are removed.
Parse::PMFile usually parses a module version in a Safe compartment. However, this approach doesn't work smoothly under older perls (prior to 5.10) plus some combinations of recent versions of Safe.pm (2.24 and above) and version.pm (0.9905 and above) for various reasons. As of version 0.27, Parse::PMFile simply uses "eval" to parse a version under older perls. If you want it to use always "eval" (even under recent perls), set this to true.

parse

takes a path to a .pm file, and returns a hash reference that holds information for package(s) found in the file.
