parse::debian::packages
Parse::Debian::Packages(3pm) User Contributed Perl Documentation Parse::Debian::Packages(3pm)
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.
