DESCRIPTION

Parse::Debian::PackageDesc parses a Debian .changes file (or a .dsc file) and allows you to retrieve its information easily. It can even check for GPG signatures, assuming you have GNUPG installed and an appropriate configuration.

SUBROUTINES/METHODS

CLASS METHODS

new($path)

new($path, %user_opts)

Creates a new object representing the .changes or .dsc file in $path. The only valid option for %user_opts is gpg_homedir, which points to the GNUPG home directory with the appropriate options and keyrings for GPG signature validation.

INSTANCE METHODS

path

Returns the changes/dsc file path (the one given in the constructor).

date

Returns the latest package revision date.

name

source

Returns the name of the source package.

version

Returns the full package version.

upstream_version

Returns the upstream version of the package. For native packages, the full version is returned.

debian_revision

Returns just the Debian revision of the package. So, if the full version is 3.15-5, it returns just 5. For native packages, "" is returned.

distribution

Returns the distribution the package is for.

urgency

Returns the urgency for the package.

files

Returns the list of files referenced by the changes/dsc file.

binary_package_files
