Formatting

pre-commit

Pre-commit (https://pre-commit.com/) is mainly used for applying the formatting rules automatically. Therefore, it is strongly encouraged to use it at or before git-commit. Pre-commit is set-up and used in the following way:

• Installed by pip install pre-commit, conda install pre_commit or see https://pre-commit.com/#install.
• pre-commit hook is installed by pre-commit install.
• pre-commit hook is run by pre-commit run --all-files.

Unless running pre-commit, pre-commit.ci may push the fix at PR by github action. In this case, the fix should be merged by the contributor's repository.

VSCode setting

  "ruff.lint.args": [
      "--config=${workspaceFolder}/pyproject.toml",
  ],
