NAME

DPKG::Parse - Parse various dpkg files into Perl Objects

SYNOPSIS

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

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

DESCRIPTION

DPKG::Parse contains utilities to parse the various files created by dpkg and turn them into helpful Perl objects. Current files understood by various DPKG::Parse modules:

  /var/lib/dpkg/status    - DPKG::Parse::Status
  /var/lib/dpkg/available - DPKG::Parse::Available
  Packages.gz             - DPKG::Parse::Packages

See each module's documentation for particulars - You should not be calling DPKG::Parse directly.

METHODS

filename($filename)

A simple accessor for the file currently being parsed.

entryarray

Access to the raw array of entries in a given file.

entryhash

Access to the raw hash of entries. The key is determined by the module, but is usually the Package name.

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

A generic new function; takes a filename and calls the filename() accessor with it. Should not be called directly, but through on of the children of this package.

parse

A default parse function; simply calls parse_package_format.

parse_package_format

Takes a file in a format similar to the dpkg "available" file, and creates DPKG::Parse::Entry objects from each entry.

get_package('name' => 'postfix', 'hash' => 'entryhash');

The value of a hash, if it exists. By default, it uses the value returned by the "entryhash" accessor, but that can be overridden with the "hash" parameter. Usually returns a DPKG::Parse::Entry object.

next_package

Shifts the next value off the array stored in the entryarray() accessor. If you want to access the raw values, do not use this function! It shifts!
