Get Started!

Ready to contribute? Here’s how to set up codex-africanus for local development.

  1. Fork the codex-africanus repo on GitHub.

  2. Clone your fork locally:

    $ git clone
  3. Install your local copy into a virtualenv. Assuming you have virtualenvwrapper installed, this is how you set up your fork for local development:

    $ python -m venv ./africanus
    $ source ./africanus/bin/activate
    $ pip install -e .
  4. Install the pre-commit hooks

    $ pip install pre-commit $ pre-commit install

  5. Create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature

    Now you can make your changes locally.

  6. When you’re done making changes, check that your changes pass the test cases, fixup your PEP8 compliance, and check for any code style issues:

    $ py.test -vvv africanus $ pre-commit run -a

  7. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit -m "Your detailed description of your changes."
    $ git push origin name-of-your-bugfix-or-feature
  8. Submit a pull request through the GitHub website.

Pull Request Guidelines

Before you submit a pull request, check that it meets these guidelines:

  1. The pull request should include tests.

  2. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring, and add the feature to the list in HISTORY.rst.

  3. The pull request should work for Python 3.9 and above.


To run the tests:

$ py.test -vvv africanus/


A reminder for the maintainers on how to deploy.

  1. Update HISTORY.rst with the intended release number Z.Y.X and commit to git.

  2. Bump the version number with bumpversion. This creates a new git commit, as well as an annotated tag Z.Y.X for the release. If your current version is Z.Y.W and the new version is Z.Y.X call:

    $ python -m pip install bump2version
    $ bump2version --current-version Z.Y.W --new-version Z.Y.X patch
  3. Push the release commit and new tag up:

    $ git push --follow-tags
  4. Travis should automatically deploy the tagged release to PyPI if the automated tests pass.
