Version

A version is a string that matches the following regex:

"^v?(\d+)(?:.(\d+))?(?:.(\d+))?(?:-?(a|b|rc)(\d+)?)?$"

E.g. v0.11.22-rc3.

Assumptions

1. v1 is equivalent to v1.0.0
2. A version without a candidate is greater than its candidate counterpart e.g. v2 > v2rc > v2b > v2a

Installation

pip install rtimbo-version

Usage

>>> from version import Version
>>> v1 = Version("v0.2.11rc3")
>>> v1.major
0
>>> v1.minor
2
>>> v1.patch
11
>>> v1.candidate
'rc'
>>> v1.candidate_number
3
>>> v1 > 0
True
>>> v1 > 1
False
