Compare FreeBSD pkg files by metadata

pkgdiff is a plugin for the FreeBSD package manager pkg as well as a Python extension for comparing package files by their metadata.

To that end it uses libpkg (distributed along with the pkg commandline tools), to open and parse package files and either a basic string compare or a line-by-line diff algorithm to complare the metadata fields.

How to install

The Python extension is easily installed by running:

pip install pkgdiff

Basic usage

import pkgdiff

if pkgdiff.compare('pkg-1.14.5.txz', 'pkg-1.14.6.txz', exclude=['version']):
    print('packages are equal (ignoring version)')
