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:
- ALLOW_DEV_VERSION
- 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.
- VERBOSE
- Set this to true if you need to know some details.
- FORK
- 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.
- USERID, PERMISSIONS
- 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.
- UNSAFE
- 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.
