NAME

6       Parse::PMFile - parses .pm file as PAUSE does
7

SYNOPSIS

9           use Parse::PMFile;
10
11           my $parser = Parse::PMFile->new($metadata, {VERBOSE => 1});
12           my $packages_info = $parser->parse($pmfile);
13
14           # if you need info about invalid versions
15           my ($packages_info, $errors) = $parser->parse($pmfile);
16
17           # to check permissions
18           my $parser = Parse::PMFile->new($metadata, {
19               USERID => 'ISHIGAKI',
20               PERMISSIONS => PAUSE::Permissions->new,
21           });

DESCRIPTION

24       The most of the code of this module is taken from the PAUSE code as of
25       April 2013 almost verbatim. Thus, the heart of this module should be
26       quite stable. However, I made it not to use pipe ("-|") as well as I
27       stripped database-related code. If you encounter any issue, that's most
28       probably because of my modification.
29
30       This module doesn't provide features to extract a distribution or parse
31       meta files intentionally.

METHODS

34   new
35       creates an object. You can also pass a hashref taken from META.yml etc,
36       and an optional hashref. Options are:
37
38       ALLOW_DEV_VERSION
39           Parse::PMFile usually ignores a version with an underscore as PAUSE
40           does (because it's for a developer release, and should not be
41           indexed). Set this option to true if you happen to need to keep
42           such a version for better analysis.
43
44       VERBOSE
45           Set this to true if you need to know some details.
46
47       FORK
48           As of version 0.17, Parse::PMFile stops forking while parsing a
49           version for better performance. Parse::PMFile should return the
50           same result no matter how this option is set, but if you do care,
51           set this to true to fork as PAUSE does.
52
53       USERID, PERMISSIONS
54           As of version 0.21, Parse::PMFile checks permissions of a package
55           if both USERID and PERMISSIONS (which should be an instance of
56           PAUSE::Permissions) are provided. Unauthorized packages are
57           removed.
58
59       UNSAFE
60           Parse::PMFile usually parses a module version in a Safe
61           compartment. However, this approach doesn't work smoothly under
62           older perls (prior to 5.10) plus some combinations of recent
63           versions of Safe.pm (2.24 and above) and version.pm (0.9905 and
64           above) for various reasons. As of version 0.27, Parse::PMFile
65           simply uses "eval" to parse a version under older perls. If you
66           want it to use always "eval" (even under recent perls), set this to
67           true.
68
69   parse
70       takes a path to a .pm file, and returns a hash reference that holds
71       information for package(s) found in the file.
