Options:
-l, --line-length INTEGER Where to wrap around. [default: 88]
+ --py36 Allow using Python 3.6-only syntax on all input
+ files. This will put trailing commas in function
+ signatures and calls also after *args and
+ **kwargs. [default: per-file auto-detection]
+ --pyi Format all input files like typing stubs
+ regardless of file extension (useful when piping
+ source on standard input).
+ -S, --skip-string-normalization
+ Don't normalize string quotes or prefixes.
--check Don't write the files back, just return the
status. Return code 0 means nothing would
change. Return code 1 means some files would be
for each file on stdout.
--fast / --safe If --fast given, skip temporary sanity checks.
[default: --safe]
- -q, --quiet Don't emit non-error messages to stderr. Errors
- are still emitted, silence those with
- 2>/dev/null.
- --pyi Consider all input files typing stubs regardless
- of file extension (useful when piping source on
- standard input).
- --py36 Allow using Python 3.6-only syntax on all input
- files. This will put trailing commas in function
- signatures and calls also after *args and
- **kwargs. [default: per-file auto-detection]
- -S, --skip-string-normalization
- Don't normalize string quotes or prefixes.
--include TEXT A regular expression that matches files and
directories that should be included on
recursive searches. On Windows, use forward
slashes for directories. [default:
build/|buck-out/|dist/|_build/|\.git/|\.hg/|
\.mypy_cache/|\.tox/|\.venv/]
-
+ -q, --quiet Don't emit non-error messages to stderr. Errors
+ are still emitted, silence those with
+ 2>/dev/null.
+ -v, --verbose Also emit messages to stderr about files
+ that were not changed or were ignored due to
+ --exclude=.
--version Show the version and exit.
--help Show this message and exit.

hooks:
- id: black
args: [--line-length=88, --safe]

```
Then run `pre-commit install` and you're ready to go.
`args` in the above config is optional but shows you how you can change
the line length if you really need to. If you're already using Python
-3.7, switch the `python_version` accordingly. Finally, `stable` is a tag
+3.7, switch the `language_version` accordingly. Finally, `stable` is a tag
that is pinned to the latest release on PyPI. If you'd rather run on
master, this is also an option.
