Pylint is developed using the git distributed version control system.
You can clone Pylint using
git clone https://github.com/pylint-dev/pylint
Before you start testing your code, you need to install your source-code package locally.
Suppose you just cloned pylint with the previous
git clone command. To set up your
environment for testing, open a terminal and run:
cd pylint python3 -m venv venv source venv/bin/activate pip install -r requirements_test_min.txt pip install -e .
This ensures your testing environment is similar to Pylint's testing environment on GitHub.
Optionally (Because there's an auto-fix if you open a merge request): We have
pre-commit hooks which should take care of the autoformatting for you before each
commit. To enable it, run
pre-commit install in the
pylint root directory.
Even more optionally: You can enable slow on push hooks with
pre-commit install --install-hooks -t pre-push.
It will do slow checks like checking that the generated documentation is up to date
before each push.
If you're testing new changes in astroid you need to also clone astroid and install with an editable installation alongside pylint as follows:
# Suppose you're in the pylint directory git clone https://github.com/pylint-dev/astroid.git python3 -m pip install -e astroid/
You're now using the local astroid in pylint and can control the version with git for example:
cd astroid/ git switch my-astroid-dev-branch
