This is a Jazzband project. By contributing you agree to abide by the Contributor Code of Conduct and follow the guidelines.

How can you contribute?

Contributions in all forms are welcome, not only code patches. You can contribute by:

  • reporting bugs/issues
  • triaging reported issues
  • improving the documentation
  • suggesting enhancements

Of course, if you report a bug or have a feature request, a pull request implementing the fix or feature is much appreciated.

Contributing code

If you decide to submit a patch or implement a feature, please adhere to the quality checks:

  • Pull requests must be accompanied by tests. We use pytest and prefer using this testing style over Django's django.test.TestCase.
  • Ideally, documentation updates are included in a pull request.
  • Imports are sorted using isort, while code is formatted using black. There are tox environments and CI checks in place to check/enforce this.
  • Follow Django's code style where possible.
  • Keep commits atomic - one commit should only concern one topic. Bugfixes typically have one commit for the regression test and one commit with the fix.

Setting up the project for local development

After checking out the project (through git clone), it's advised to set up a virtualenv with the lowest supported python and Django version.

You can then install the project with all the dev-tools:

pip install -e .[tests,pep8,coverage,docs,release]

Running the testapp as dev environment

In Django project's, you are typically expecting a manage.py file. This is less common in libraries, but it's fairly straightforward to emulate this:

export DJANGO_SETTINGS_MODULE=testapp.settings

django-admin migrate
django-admin createsuperuser
django-admin runserver

You can now start working on your contribution!

Running the tests

Run the tests locally using tox to verify everything is okay:

tox

Cheat sheet

This cheat sheet provides some quick tooling/commands lookup while working on the project.

Running tests

In your current environment

pytest

or to build the full test matrix

tox

Formatting the code for check-in

black .
isort .

Should be sufficient. Consider using a pre-commit hook to automate this.

Building the docs

cd docs
make html

You can now open the file _build/html/index.html in your browser.

Generating message catalogs

export DJANGO_SETTINGS_MODULE=testapp.settings
django-admin makemessages --all

After translating the message, you need to compile the message catalogs:

django-admin compilemessages

Bumping the version/releasing

After updating changelogs etc.

tbump {new-version} --only-patch
git commit -am ":bookmark: Bump to version <X.Y.Z>"
git tag -s X.Y.Z
git push origin master --tags
