NAME

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

NOTE

EXPERIMENTAL => "use at your own risk"; # you have bin warned

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://pkg-perl.alioth.debian.org/~jozef-guest/pmindex/     lenny   main contrib non-free
deb http://pkg-perl.alioth.debian.org/~jozef-guest/pmindex/     squeeze main contrib non-free
deb http://pkg-perl.alioth.debian.org/~jozef-guest/pmindex/     wheezy  main contrib non-free
deb http://pkg-perl.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

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/.

clean

Remove all files from cache folder.
