NAME
Parse::Debian::Packages - parse the data from a debian Packages.gz SYNOPSIS
use YAML; use IO::File; use Parse::Debian::Packages; my $fh = IO::File->new("Packages"); my $parser = Parse::Debian::Packages->new( $fh ); while (my %package = $parser->next) { print Dump \%package; } DESCRIPTION
This module parses the Packages files used by the debian package management tools. It presents itself as an iterator. Each call of the ->next method will return the next package found in the file. For laziness, we take a filehandle in to the constructor. Please open the file for us. METHODS
new( $filehandle ) next Iterate to the next package in the file, returns either a hash containing a package description, or false at end of file. as_hash( $filehandle ) Return all the packages from a filehandle as a hash of hashes. AUTHOR
