About

A standalone variant of distutils.version and packaging.version, without anything else.

verlib is the implementation of PEP 386. verlib2 is the implementation of PEP 440. It also includes the original distutils.version implementation, for those who need it going forward.

Rationale

Everyone needs to compare versions, but no one wants to add packaging as a dependency. distutils is deprecated, and Python 3.12 removed it from the standard library.

Setup

pip install verlib2

Usage

from verlib2 import Version

assert Version("1.0.dev456") < Version("1!1.2.rev33+123456") 

Note: verlib2.Version provides packaging's Version, while both implementations can be accessed like this:

from verlib2.distutils.version import LooseVersion, StrictVersion
from verlib2.packaging.version import Version
