NAME Debian::Apt::PM - locate Perl Modules in Debian repositories NOTE Needs following extra Debian packages `libdpkg-perl' and `libapt-pkg-perl'.

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.
