Ruff

Ruff can be used to replace Flake8, Black, isort, pydocstyle, pyupgrade, autoflake, etc., and yet run tens to hundreds of times faster than the individual tools.

To change the configuration, it is necessary to rewrite ruff.toml, and it is recommended to set it to ignore conflicts such as the following:

ignore = [
    "COM812", "COM819",
    "D100", "D203", "D213", "D300",
    "E111", "E114", "E117",
    "ISC001", "ISC002",
    "Q000", "Q001", "Q002", "Q003",
    "W191",
]

pre-commit

The .pre-commit-config.yaml file can contain scripts to be executed before commit.

# Python Formatter
uv run ruff format .

# Python Linter
uv run ruff check . --fix

# Docker Linter
hodolint Dockerfile

Appendix

Install libraries

Only sync based on the production lockfile (requirements.lock) instead of the development lockfile (requirements-dev.lock).

# Install also include develop dependencies
uv sync

# If you do not want dev dependencies to be installed
uv sync --no-dev

# Use the add command to add dependencies to your project
uv add {libraries}
