Java – Python module for handling software versions

• Java

I am looking for a python module / library that will run on the 'software version'... Which means, for example:

>Compare versions "1.0-snapshot" and "1.1-snapshot" and tell which update > increase "1.0.1-snapshot" to "1.0.2-snapshot" > make "1.0" from "1.0-snapshot" and the same as "- release"

Yes, version naming comes from the Java (Maven) world - my Python part should operate on them

Any ideas?

Solution

Distutils has some support for this

>>> from distutils.version import LooseVersion  # or StrictVersion
>>> LooseVersion("1.0-SNAPSHOT") < LooseVersion("1.1-SNAPSHOT")
True
>>> v = LooseVersion("1.0.1-SNAPSHOT")
>>> v.version
[1,1,'-SNAPSHOT']

You have to do incremental and other operations yourself
