versus 0.1.3

Package version comparison made easy.

Package version comparison made easy.

versus is a standalone, portable, dependency-free library for comparing package versions from within the code. It supports variety of lookups, such as lte, lt, gte, gt and eq.

Prerequisites

Python 3.9+

Installation

pip

pip install versus

Download and copy

versus.py is the sole, self-contained module of the package. It includes tests too. If it’s more convenient to you, you could simply download the versus.py module and include it in your repository.

Since tests are included, it won’t have a negative impact on your test coverage (you might need to tweak your test/coverage configuration).

Usage

Comparing Django versions.

from versus import get_version

django_version = get_version("django")
print(django_version)  # 5.2.1

django_version.gte("4.2")  # True
django_version.gte("5.2")  # True
django_version.gte("5.2.1")  # True
django_version.gte("5.2.2")  # False

Comparing sphinx-autobuild versions:

sphinx_autobuild_version = get_version("sphinx-autobuild")
print(sphinx_autobuild_version)  # 2024.10.3

sphinx_autobuild_version.gte("1.0")  # True
sphinx_autobuild_version.gte("2024.09")  # True
sphinx_autobuild_version.gte("2024.11")  # False
sphinx_autobuild_version.lte("2024.11")  # True

Non-existent/non-installed package lookup would return None:

nonexistent_package = get_version("nonexistent-package")
print(nonexistent_package)  # None

Tests

Run the tests with unittest:

python -m unittest versus

Or pytest:

pytest
