```yaml
repos:
- - repo: https://github.com/psf/black
- rev: stable # Replace by any tag/version: https://github.com/psf/black/tags
+ # Using this mirror lets us use mypyc-compiled black, which is about 2x faster
+ - repo: https://github.com/psf/black-pre-commit-mirror
+ rev: 23.10.0
hooks:
- id: black
- language_version: python3 # Should be a command that runs python3.6+
+ # It is recommended to specify the latest version of Python
+ # supported by your project here, or alternatively use
+ # pre-commit's default_language_version, see
+ # https://pre-commit.com/#top_level-default_language_version
+ language_version: python3.11
```
+
+Feel free to switch out the `rev` value to a different version of Black.
+
+Note if you'd like to use a specific commit in `rev`, you'll need to swap the repo
+specified from the mirror to https://github.com/psf/black. We discourage the use of
+branches or other mutable refs since the hook [won't auto update as you may
+expect][pre-commit-mutable-rev].
+
+## Jupyter Notebooks
+
+There is an alternate hook `black-jupyter` that expands the targets of `black` to
+include Jupyter Notebooks. To use this hook, simply replace the hook's `id: black` with
+`id: black-jupyter` in the `.pre-commit-config.yaml`:
+
+```yaml
+repos:
+ # Using this mirror lets us use mypyc-compiled black, which is about 2x faster
+ - repo: https://github.com/psf/black-pre-commit-mirror
+ rev: 23.10.0
+ hooks:
+ - id: black-jupyter
+ # It is recommended to specify the latest version of Python
+ # supported by your project here, or alternatively use
+ # pre-commit's default_language_version, see
+ # https://pre-commit.com/#top_level-default_language_version
+ language_version: python3.11
+```
+
+```{note}
+The `black-jupyter` hook became available in version 21.8b0.
