If +you feel this PR not require a changelog entry please state that in a comment and a +maintainer can add a `skip news` label to make the CI pass. Otherwise, please ensure you +have a line in the following format: -If you're fixing a bug, add a test. Run it first to confirm it fails, -then fix the bug, run it again to confirm it's really fixed. +```md +- `Black` is now more awesome (#X) +``` + +To workout X, please use +[Next PR Number](https://ichard26.github.io/next-pr-number/?owner=psf&name=black). This +is not perfect but saves a lot of release overhead as now the releaser does not need to +go back and workout what to add to the `CHANGES.md` for each release. + +### Style Changes + +If a change would affect the advertised code style, please modify the documentation (The +_Black_ code style) to reflect that change. Patches that fix unintended bugs in +formatting don't need to be mentioned separately though. + +### Docs Testing + +If you make changes to docs, you can test they still build locally too. + +```console +$ pip install -r docs/requirements.txt +$ pip install [-e] .[d] +$ sphinx-build -a -b html -W docs/ docs/_build/ +``` + +## black-primer + +`black-primer` is used by CI to pull down well-known _Black_ formatted projects and see +if we get source code changes. It will error on formatting changes or errors. Please run +before pushing your PR to see if you get the actions you would expect from _Black_ with +your PR. You may need to change +[primer.json](https://github.com/psf/black/blob/master/src/black_primer/primer.json) +configuration for it to pass. + +For more `black-primer` information visit the +[documentation](https://github.com/psf/black/blob/master/docs/black_primer.md). + +## Hygiene -If adding a new feature, add a test.
