NAME ^

Debian::Apt::PM - locate Perl Modules in Debian repositories

NOTE ^

Needs following extra Debian packages libdpkg-perl and libapt-pkg-perl.

SYNOPSIS ^

command line:

        apt-pm update
        apt-pm find Moose
        dpkg-scanpmpackages /path/to/debian/repository
        
        # print out all dependencies of an unpacked distribution that are packaged for Debian
        perl -MDebian::Apt::PM -MModule::Depends -le \
                '$apm=Debian::Apt::PM->new();$md=Module::Depends->new->dist_dir(".")->find_modules; %r=(%{$md->requires},%{$md->build_requires}); while (($m, $v) = each %r) { $f=$apm->find($m, $v); print $f->{"min"}->{"package"} if $f->{"min"}  }' \
                | sort \
                | uniq \
                | xargs echo apt-get install
        # print out all dependencies of an unpacked distribution that are not packaged for Debian
        perl -MDebian::Apt::PM -MModule::Depends -le \
                '$apm=Debian::Apt::PM->new();$md=Module::Depends->new->dist_dir(".")->find_modules; %r=(%{$md->requires},%{$md->build_requires}); while (($m, $v) = each %r) { $f=$apm->find($m, $v); print $m, " ", $v if not $f->{"min"}  }'

Module:

        my $aptpm = Debian::Apt::PM->new(sources => [ 'PerlPackages.bz2' ])
        $aptpm->update;
        my %moose_locations = $aptpm->find('Moose');

USAGE ^

COMMAND-LINE USAGE

Add sources for Debian releases and components. Here is the complete list that can be reduced just to the wanted ones:

        cat >> /etc/apt/sources.list << __END__
        # for apt-pm
        deb http://alioth.debian.org/~jozef-guest/pmindex/     lenny   main contrib non-free
        deb http://alioth.debian.org/~jozef-guest/pmindex/     squeeze main contrib non-free
        deb http://alioth.debian.org/~jozef-guest/pmindex/     wheezy  main contrib non-free
        deb http://alioth.debian.org/~jozef-guest/pmindex/     sid     main contrib non-free

        __END__

Fetch the indexes:

        apt-pm update

Look for the CPAN modules:

        apt-pm find Moose
        # libmoose-perl_0.17-1_all: Moose 0.17
        # libmoose-perl_0.94-1_i386: Moose 0.94
        # libmoose-perl_0.97-1_i386: Moose 0.97
        # libmoose-perl_0.54-1_all: Moose 0.54

Look for the non-CPAN modules:

        apt-pm find Purple        
        # libpurple0_2.4.3-4lenny5_i386: Purple 0.01
        
        apt-pm find Dpkg::Version
        # dpkg-dev_1.14.28_all: Dpkg::Version 0

METHODS ^

new()

Object constructor.

PROPERTIES

sources

isa => 'ArrayRef' of files that will be read to construct the lookup. By default it is filled with files from /var/cache/apt/apt-pm/.

cachedir

Is the folder where indexes cache files will be stored. Default is /var/cache/apt/apt-pm/deb/.

repo_type

deb|deb-src

packages_dependencies

Path to 02packages.dependencies.txt(.gz)? file.

find($module_name, [$min_version])

Returns hash with Perl versions as key and hash value having Debian version and package name. Example:

        {
                '0.94' => {
                        'version' => '0.94-1',
                        'package' => 'libmoose-perl'
                        'arch'    => 'i386'
                },
                '0.97' => {
                        'version' => '0.97-1',
                        'package' => 'libmoose-perl'
                        'arch'    => 'i386'
                },
                '0.54' => {
                        'version' => '0.54-1',
                        'package' => 'libmoose-perl'
                        'arch'    => 'i386'
                },
        };

If $min_version is set, returns min and max keys. max has always the highest version:

        'max' => {
                'version' => '0.97-1',
                'package' => 'libmoose-perl'
                'arch'    => 'i386'
        },

min is changing depending on $min_version. Examples:

        $min_version = '0.01';
        'min' => {
                'version' => '0.54-1',
                'package' => 'libmoose-perl'
                'arch'    => 'i386'
        },
        $min_version = '0.93';
        'min' => {
                'version' => '0.94-1',
                'package' => 'libmoose-perl'
                'arch'    => 'i386'
        },
        $min_version = '1.00';
        'min' => undef,

update

Scans the /etc/apt/sources.list and /etc/apt/sources.list.d/*.list repositories for PerlPackages.bz2 and prepares them to be used for find. All PerlPackages.bz2 are stored to /var/cache/apt/apt-pm/.

It also fetches http://pkg-perl.alioth.debian.org/cpan2deb/CPAN/02packages.dependencies.txt.gz to be used by apt-cpan.

clean

Remove all files from cache folder.

resolve_install_depends($force_all, @modules)

Returns two array references one with Debian packages, the other with CPAN packages that needs to be installed on current system for the given list of @modules.

Option $force_all (true/false) choose to include all dependencies not just the ones that needs to be installed.

module_depends($module)

Return all Perl modules and Debian packages $module has as dependency.
