NAME

6       Alien::Packages - Find information of installed packages
7

SYNOPSIS

9           my $ap = Alien::Packages->new();
10
11           my @packages = $ap->list_packages();
12           foreach my $pkg (@packages)
13           {
14               print "$pkg->[0] version $pkg->[1]: $pkg->[2]\n";
15           }
16
17           my %perl_owners = $ap->list_fileowners( File::Spec->rel2abs( $^X ) );
18           while( my ($fn, $pkg) = each( %perl_owners ) )
19           {
20               print "$fn is provided by ", join( ", ", @$pkg ), "\n";
21           }
22

SUBROUTINES/METHODS

24   new
25       Instantiates new Alien::Packages object. Attributes can be specified
26       for used finder (of type Module::Pluggable::Object). Additionally,
27
28       "only_loaded"
29           Use only plugins which are still loaded.
30
31       can be specified with a true value. This forces to grep %INC instead of
32       using Module::Pluggable.
33
34   list_packages
35       Lists the installed packages on the system (if the caller has the
36       permission to do).
37
38       Results in a list of array references, whereby each item contains:
39
40         {
41             PkgType => $pkg_type, # e.g. 'dpkg', 'pkgsrc', ...
42             Package => $pkg_name,
43             Version => $version,
44             Summary => $summary,
45         }
46
47       "type" is the packager type, e.g. rpm, lpp or pkgsrc.
48
49   list_fileowners
50       Provides an association between files on the system and the package
51       which reference it (has presumably installed it).
52
53       Returns a hash with the files names as key and a list of referencing
54       package names as value:
55
56         '/absolute/path/to/file' =>
57             [
58                 {
59                     PkgType => $pkg_type,
60                     Package => $pkg_name,
61                 }
62             ],
63         ...

GETTING HELP

69       To get novice help, it's usually recommended to ask on typical
70       platforms like PerlMonks.  To help you make the best use of the
71       PerlMonks platform, and any other lists or forums you may use, I
72       strongly recommend that you read "How To Ask Questions The Smart Way"
73       by Eric Raymond: <http://www.catb.org/~esr/faqs/smart-questions.html>.
74
75       If you really asks a question what noone can answer, please drop me a
76       note with the question URL to either my CPAN address or on
77       "irc.perl.org" in the channels "#toolchain" or "#devops". I'll try to
78       answer as best as I can (and as soon, as possible, of course).
79
80   Where can I go for help with a concrete version?
81       Bugs and feature requests are accepted against the latest version only.
82       To get patches for earlier versions, you need to get an agreement with
83       a developer of your choice - who may or not report the issue and a
84       suggested fix upstream (depends on the license you have chosen).
85
86   Business support and maintenance
87       For business support you can contact Jens via his CPAN email address
88       rehsackATcpan.org. Please keep in mind that business support is neither
89       available for free nor are you eligible to receive any support based on
90       the license distributed with this package.

RESOURCES AND CONTRIBUTIONS

130       There're several ways how you can help to support future development:
131       You can hire the author to implement the features you require at most
132       (this also defines priorities), you can negotiate a support and
133       maintenance contract with the company of the author and you can provide
134       tests and patches. Further, you can submit documentation and links to
135       resources to improve or add packaging systems or grant remote access to
136       machines with insufficient supported packaging tools.
