Contribution Guidelines

Contributions are welcome, and they are greatly appreciated! Every little bit helps, and credit will always be given.

You can contribute in many ways:

Types of Contributions

Report Bugs

Report bugs via Github Issues.

If you are reporting a bug, please include:

  • Your version of this package, python and Numba (if you use it)
  • Any other details about your local setup that might be helpful in troubleshooting, e.g. operating system.
  • Detailed steps to reproduce the bug.
  • Detailed description of the bug (error log etc.).

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 “help wanted” and not assigned to anyone is open to whoever wants to implement it - please leave a comment to say you have started working on it, and open a pull request as soon as you have something working, so that Travis starts building it.

Issues without “help wanted” generally already have some code ready in the background (maybe it’s not yet open source), but you can still contribute to them by saying how you’d find the fix useful, linking to known prior art, or other such help.

Write Documentation

Probably for some features the documentation is missing or unclear. You can help with that!

Submit Feedback

The best way to send feedback is to file an issue via Github Issues.

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. Create multiple issues if necessary.
  • Remember that this is a volunteer-driven project, and that contributions are welcome :)

Get Started!

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

  • Fork this repo on GitHub.

  • Clone your fork locally

  • To make changes, create a branch for local development:

    $ git checkout -b name-of-your-bugfix-or-feature
    
  • Check out the instructions and notes in publish.py

  • Install tox and run the tests:

    $ pip install tox
    $ tox
    

    The tox.ini file defines a large number of test environments, for different Python etc., plus for checking codestyle. During development of a feature/fix, you’ll probably want to run just one plus the relevant codestyle:

    $ tox -e codestyle
    
  • 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
    
  • Submit a pull request through the GitHub website. This will trigger the Travis CI build which runs the tests against all supported versions of Python.
