Radon CI

A Python script that uses Radon to compute Cyclomatic Complexity and Mantainability Index, and generates output files in OpenMetrics and CodeClimate format. Mainly intended to run in Gitlab CI pipelines.

Installation

First, create a virtual environment, for example using venv:

python3.13 -m venv .venv
source .venv/bin/activate

Then install the package:

pip install .

Or in editable mode:

pip install -e .
