DPKG::Parse::Status - Parse the "status" file

SYNOPSIS

Top

    use DPKG::Parse::Status;

    my $status = DPKG::Parse::Status->new;
    while (my $entry = $status->next_package) { 
        print $entry->package . " " . $entry->version . "\n";
    }

    my $postfix = $status->get_package('name' => 'postfix');

    my $postfix = $status->get_installed('name' => 'postfix');

DESCRIPTION

Top

DPKG::Parse::Status parses a dpkg "status" file and turns each entry into a DPKG::Parse::Entry object. By default, it uses the Debian default location of "/var/lib/dpkg/status".

See DPKG::Parse for more information on the get_package and next_package methods.

See DPKG::Parse::Entry for more information on the entry objects.

METHODS

Top

new('filename' => '/var/lib/dpkg/status')

Creates a new DPKG::Parse::Status object. By default, it tries to open /var/lib/dpkg/status.

parse

Calls DPKG::Parse::parse, and populates the "installed" accessor with a hash of packages whose "status" is "install ok installed".

get_installed('name' => 'postfix');

Returns a DPKG::Parse::Entry object for the given package, or undef if it's not found.
