ruff-shared.toml

# Generic shared Ruff configuration file. It should be possible to use this
# file unmodified in different packages provided that one likes the style that
# it enforces.
#
# This file should be used from pyproject.toml as follows:
#
#     [tool.ruff]
#     extend = "ruff-shared.toml"
#
# It can then be extended with project-specific rules. A common additional
# setting in pyproject.toml is tool.ruff.lint.extend-per-file-ignores, to add
# additional project-specific ignore rules for specific paths.
#
# The rule used with Ruff configuration is to disable every non-deprecated
# lint rule that has legitimate exceptions that are not dodgy code, rather
# than cluttering code with noqa markers. This is therefore a reiatively
# relaxed configuration that errs on the side of disabling legitimate rules.
#
# Reference for settings: https://docs.astral.sh/ruff/settings/
# Reference for rules: https://docs.astral.sh/ruff/rules/
