NAME
Alien::Packages - Find information of installed packages
SYNOPSIS
my $ap = Alien::Packages->new();
my @packages = $ap->list_packages();
foreach my $pkg (@packages)
{
print "$pkg->[0] version $pkg->[1]: $pkg->[2]\n";
}
my %perl_owners = $ap->list_fileowners( File::Spec->rel2abs( $^X ) );
while( my ($fn, $pkg) = each( %perl_owners ) )
{
print "$fn is provided by ", join( ", ", @$pkg ), "\n";
}
SUBROUTINES/METHODS
new
Instantiates new Alien::Packages object. Attributes can be specified for
used finder (of type Module::Pluggable::Object). Additionally,
`only_loaded'
Use only plugins which are still loaded.
can be specified with a true value. This forces to grep `%INC' instead
of using Module::Pluggable.
list_packages
Lists the installed packages on the system (if the caller has the
permission to do).
Results in a list of array references, whereby each item contains:
{
PkgType => $pkg_type, # e.g. 'dpkg', 'pkgsrc', ...
Package => $pkg_name,
Version => $version,
Summary => $summary,
}
`type' is the packager type, e.g. *rpm*, *lpp* or *pkgsrc*.
list_fileowners
Provides an association between files on the system and the package
which reference it (has presumably installed it).
Returns a hash with the files names as key and a list of referencing
package names as value:
'/absolute/path/to/file' =>
[
{
PkgType => $pkg_type,
Package => $pkg_name,
}
],
...

GETTING HELP
To get novice help, it's usually recommended to ask on typical platforms
like PerlMonks. To help you make the best use of the PerlMonks platform,
and any other lists or forums you may use, I strongly recommend that you
read "How To Ask Questions The Smart Way" by Eric Raymond:
http://www.catb.org/~esr/faqs/smart-questions.html.
If you really asks a question what noone can answer, please drop me a
note with the question URL to either my CPAN address or on
`irc.perl.org' in the channels `#toolchain' or `#devops'. I'll try to
answer as best as I can (and as soon, as possible, of course).
Where can I go for help with a concrete version?
Bugs and feature requests are accepted against the latest version only.
To get patches for earlier versions, you need to get an agreement with a
developer of your choice - who may or not report the issue and a
suggested fix upstream (depends on the license you have chosen).
Business support and maintenance
For business support you can contact Jens via his CPAN email address
rehsackATcpan.org. Please keep in mind that business support is neither
available for free nor are you eligible to receive any support based on
the license distributed with this package.
BUGS
This module is alpha software, the API may change in future releases.
See Alien::Packages::Roadmap for more details.

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