Fix Bugs

Look through the GitHub issues for bugs. Anything tagged with “bug” is open to whoever wants to implement it.

Implement Features

Look through the GitHub issues for features. Anything tagged with “feature” is open to whoever wants to implement it.

Write Documentation

Groupy could always use more documentation, whether as part of the official Groupy docs, in docstrings, or even on the web in blog posts, articles, and such.

Submit Feedback

The best way to send feedback is to file an issue at

If you are proposing a feature:

  • Explain in detail how it would work.
  • Keep the scope as narrow as possible, to make it easier to implement.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

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

  1. Fork the Groupy repo on GitHub.

  2. Clone your fork locally:

    $ git clone
  3. Install your local copy into a virtualenv. Since 3.3, Python ships with its own virutal environment creator: venv. Usage is simple:

    $ cd Groupy/
    $ pyvenv env
    $ source env/bin/activate
    $ pip install -r requirements.txt -r testing_requirements.txt -e .
  4. Create a branch from the dev branch for local development:

    $ git checkout -b new-hotness dev

    Now you can make your changes locally.

  5. When you’re done making changes, check that your changes pass flake8, have great coverage, and pass all tests on all supported versions of python. Sounds tough, but tox makes this easy:

    $ tox

Note that if you update requirements.txt or testing_requirements.txt you must tell tox to recreate its virtual environments using the -r flag:

$ tox -r
  1. Commit your changes and push your branch to GitHub:

    $ git add .
    $ git commit
    $ git push origin new-hotness

Please make sure to:

  • not to commit sensitive data or extra files. You can use git add -p to add parts of files if necessary.
  • follow proper git commit message standards. In particular, the first line should be under 60 characters long, and any detail should begin on the 3rd line (the second line must be blank).
  1. 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 the documentation.
  3. The pull request should work for Python 3.4, 3.5, and 3.6. Check and make sure that the tests pass for all supported Python versions.
