DESCRIPTION¶

DPKG::Parse::Entry parses a dpkg "Package" file entry, creating a new DPKG::Parse::Entry instance for it. You submit the contents, beginning with a "Package:" line, as the 'data' argument to new. After that, all the data is populated as lowercased instance methods. For example, if we used the above to create an $entry object, we would have:

   $entry->package == "kernel-image-2.6.12.2"
   $entry->size    == 4293154
   $entry->md5sum  == 2acf846b127b71a1fa1143214b2b85a9

DPKG::Parse::Entry will skip any attribute it does not know about. You can see what it has skipped by passing a true value to the 'debug' option to 'new()'.

It should know all the attributes present in a Packages, available, and status file.

See DPKG::Parse::Status, DPKG::Parse::Available, and DPKG::Parse::Packages for more information on how to easily generate DPKG::Parse::Entry objects.

METHODS¶

Accessor Methods

The following accessor methods correspond directly to the values found in the parsed Package block, with one exception: "-" characters are replaced with "_". So, "build-essential" becomes "build_essential".

The accessors are:

    architecture
    bugs
    build_essential
    conflicts
    config_version
    conffiles
    depends
    description
    enhances
    essential
    filename
    installed_size
    maintainer
    md5sum
    origin
    package
    priority
    provides
    pre_depends
    recommends
    replaces
    size
    source
    section
    suggests
    status
    task
    tag
    url
    version
    

new('data' => $data, 'debug' => 1)

Creates a new DPKG::Parse::Entry object. 'data' should be a scalar that contains the text of a dpkg-style Package entry. If the 'debug' flag is set, we will Carp about entries we don't have accessors for.

parse('data' => $data);

Does the actual parsing of the Package block given to new(). Probably should only be called once per object.
