|
|
- Auto-format a file or entire directory:
|
|
|
|
`black {{path/to/file_or_directory}}`
|
|
|
|
- Format the [c]ode passed in as a string:
|
|
|
|
`black -c "{{code}}"`
|
|
|
|
- Show whether a file or a directory would have changes made to them if they were to be formatted:
|
|
|
|
`black --check {{path/to/file_or_directory}}`
|
|
|
|
- Show changes that would be made to a file or a directory without performing them (dry-run):
|
|
|
|
`black --diff {{path/to/file_or_directory}}`
|
|
|
|
- Auto-format a file or directory, emitting exclusively error messages to `stderr`:
|
|
|
|
`black --quiet {{path/to/file_or_directory}}`
|
|
|
|
- Auto-format a file or directory without replacing single quotes with double quotes (adoption helper, avoid using this for new projects):
|
|
|
|
`black --skip-string-normalization {{path/to/file_or_directory}}`
