Get Started!

Ready to contribute? Here’s how to set up gxformat for local development.

  1. Fork the gxformat2 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:

    $ make setup-venv
  4. Create a branch for local development:

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

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass flake8 and the tests

    $ tox -e lint
    $ tox -e mypy
    $ tox -e unit
  6. 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
  7. Submit a pull request through the GitHub website.

Pull Request Guidelines

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

  1. If the pull request adds functionality, the docs should be updated. Put your new functionality into a function with a docstring.
  2. The pull request should work for Python >=3.6. Check CI results on pull request and make sure that the tests pass for all supported Python versions.


Tox is a tool to automate testing across different Python versions. The tox executable can be supplied with a -e argument to specify a testing environment. gxformat2 defines the following environments:

Lint the gxformat2 code using Python 3.7.
Lint the project Python docstrings.
Run the unit tests with Python 3.6.
