Check docs for style

Ruff has the ability to check that you have:

• Documented all public modules, classes, methods and functions

• Written your docstrings according to a particular style

• Not missed parameters from method and function docstrings

This is not turned on by default, as it is not able to distinguish between a missing docstring, and one that is inherited from a parent class

Enabling docstring checking

There are a number of competing docstring styles, ruff supports numpy, google and pep257. If you would like to check for the google docstring style, you can configure in pyproject.toml by:

• Turning on the checker

[tool.ruff.lint]
extend-select = [
    # ...
    "D",   # pydocstyle - https://docs.astral.sh/ruff/rules/#pydocstyle-d
    # ...
]

• Selecting a convention

[tool.ruff.lint.pydocstyle]
convention = "google"

• Ignoring docstring checking in tests

[tool.ruff.lint.per-file-ignores]
"tests/**/*" = [
    # ...
    "D",      # Don't check docstrings in tests
    # ...
]
