Compatibility with black
Compatibility with black is very important to the isort project and comes baked in starting with version 5. All that's required to use isort alongside black is to set the isort profile to "black".
Using a config file (such as .isort.cfg)
For projects that officially use both isort and black, we recommend setting the black profile in a config file at the root of your project's repository. This way independent to how users call isort (pre-commit, CLI, or editor integration) the black profile will automatically be applied.
For instance, your pyproject.toml file would look something like
[tool.isort] profile = "black" multi_line_output = 3
Read More about supported config files.
To use the profile option when calling isort directly from the commandline simply add the --profile black argument:
isort --profile black.
A demo of how this would look like in your .travis.yml
language: python python: - "3.6" - "3.7" - "3.8" install: - pip install -r requirements-dev.txt - pip install isort black - pip install coveralls script: - pytest my-package - isort --profile black my-package - black --check --diff my-package after_success: - coveralls
See built-in profiles for more profiles.
Integration with pre-commit
You can also set the profile directly when integrating isort within pre-commit.
