_Black_ can be installed by running `pip install black`. It requires Python 3.6.0+ to
run but you can reformat Python 2 code with it, too.
+#### Install from GitHub
+
+If you can't wait for the latest _hotness_ and want to install from GitHub, use:
+
+`pip install git+git://github.com/psf/black`
+
### Usage
To get started right away with sensible defaults:
--exclude=.
--version Show the version and exit.
- --config FILE Read configuration from PATH.
+ --config FILE Read configuration from FILE path.
-h, --help Show this message and exit.
```
expressions by Black. Use `[ ]` to denote a significant space character.

[black_primer](https://github.com/psf/black/blob/master/docs/black_primer.md) has more
information regarding its usage and configuration.
```yaml
repos:
- repo: https://github.com/psf/black
- rev: stable
+ rev: 19.10b0 # Replace by any tag/version: https://github.com/psf/black/tags
hooks:
- id: black
- language_version: python3.6
+ language_version: python3 # Should be a command that runs python3.6+
```
Then run `pre-commit install` and you're ready to go.
`stable` is a branch that tracks the latest release on PyPI. If you'd rather run on
master, this is also an option.
+## GitHub Actions
+
+Create a file named `.github/workflows/black.yml` inside your repository with:
+
+```yaml
+name: Lint
+
+on: [push, pull_request]
+
+jobs:
+ lint:
+ runs-on: ubuntu-latest
+ steps:
+ - uses: actions/checkout@v2
+ - uses: actions/setup-python@v2
+ - uses: psf/black@stable
+```
+
## Ignoring unmodified files
_Black_ remembers files it has already formatted, unless the `--diff` flag is used or
Poetry, PyPA applications (Warehouse, Bandersnatch, Pipenv, virtualenv), pandas, Pillow,
every Datadog Agent Integration, Home Assistant.
