_Black_ doesn't provide many options. You can list them by running `black --help`:
```text
-black [OPTIONS] [SRC]...
+Usage: black [OPTIONS] [SRC]...
+
+ The uncompromising code formatter.
Options:
-c, --code TEXT Format the code passed in as a string.
-l, --line-length INTEGER How many characters per line to allow.
[default: 88]
+
-t, --target-version [py27|py33|py34|py35|py36|py37|py38]
Python versions that should be supported by
Black's output. [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 reformatted. Return code 123 means
+ would be reformatted. Return code 123 means
there was an internal error.
+
--diff Don't write the files back, just output a
diff for each file on stdout.
+
+ --color / --no-color Show colored diff. Only applies when
+ `--diff` is given.
+
--fast / --safe If --fast given, skip temporary sanity
checks. [default: --safe]
+
--include TEXT A regular expression that matches files and
directories that should be included on
recursive searches. An empty value means
on all platforms (Windows, too). Exclusions
are calculated first, inclusions later.
[default: \.pyi?$]
+
--exclude TEXT A regular expression that matches files and
directories that should be excluded on
recursive searches. An empty value means no
directories on all platforms (Windows, too).
Exclusions are calculated first, inclusions
later. [default: /(\.eggs|\.git|\.hg|\.mypy
- _cache|\.nox|\.tox|\.venv|_build|buck-
+ _cache|\.nox|\.tox|\.venv|\.svn|_build|buck-
out|build|dist)/]
+
+ --force-exclude TEXT Like --exclude, but files and directories
+ matching this regex will be excluded even
+ when they are passed explicitly as arguments
+
-q, --quiet Don't emit non-error messages to stderr.
- Errors are still emitted, silence those with
+ 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.
- --config PATH Read configuration from PATH.
+ --config FILE Read configuration from PATH.
-h, --help Show this message and exit.
