You’re welcome to come and bake delicious macaroons with us :)

This project uses Poetry and pre-commit. We recommand installing those with pipx.

There are multiple ways of interacting with the project.

I just want the simple straightfoward thing

Have tox installed, run it.

$ tox

Tox is not the best way to interact with the project, but it’s certainly the easiest. Because the project uses poetry, which handles its own virtual environments, as well as pre-commit, which does too, using tox on top creates unnecessary levels, but it’s a one-liner that works.

The CI doesn’t use tox, though, so while it’s expected that if tox runs locally, the CI will be happy too, there’s no formal guarantee of that.

I want to prepare my development environment

The bootstrap script will install poetry and pre-commit through pipx for you. If pipx is not installed, it will be added too. It will also install commit hooks.

$ scripts/bootstrap

I want to run the CI checks locally

$ scripts/tests
$ scripts/lint
$ scripts/docs

Please inspect those scripts, you’ll see that they are very short. You’re free to use the command they describe directly, there’s nothing wrong in that.

I want a venv to play locally

Use poetry. Look at poetry env use python3.X if you want to work on a specific Python version.

I want a quicker feedback loop

Running poetry run takes a good second or more. If you want to speed things up, create a shell in your virtual environment:

$ poetry shell

From here, you can launch commands directly, such as pytest

I want to build the documentation

Build with:

$ tox -e docs
$ python -m webbrowser docs/_build/html/index.html

If Sphinx’s console output is localized and you would rather have it in English, use the environment variable LC_ALL=C.utf-8 (either exported or attached to the tox process)

I want to hack around

You’re invited to hack around! We have set up those tools to ease usual developpement but we’re always doing our best so that you can remove the top layers and work the way you prefer. For example: you can use pytest or black as-is, without all the tools. It’s even recommanded to remove layers when things become complicated.

The commands are in the scripts/ folder.

Core contributor additional documentation

Release a new version

There should be an active Release Draft with the changelog in GitHub releases. Make relevant edits to the changelog. Click on Release, that’s it, the rest is automated. The version number in the tag will be released version.

When creating the release, GitHub will save the release info and create a tag with the provided version. The new tag will be seen by GitHub Actions, which will then create a wheel (using the tag as version number, thanks to our, and push it to PyPI (using the new API tokens). That tag should also trigger a ReadTheDocs build, which will read GitHub releases which will write the changelog in the published documentation.


If you need to edit the name or body of a release in the GitHub UI, don’t forget to also rebuild the stable and latest doc on readthedocs.
