Micha Reiser 0c65d0c8a6 Add `lint` section to Ruff configuration ## Summary This PR adds a new `lint` section to the configuration that groups all linter-specific settings. The existing top-level configurations continue to work without any warning because the `lint.` settings are experimental. The configuration merges the top level and `lint.` settings where the settings in `lint` have higher precedence (override the top-level settings). The reasoning behind this is that the settings in `lint.` are more specific and more specific settings should override less specific settings. I decided against showing the new `lint.` options on our website because it would make the page extremely long (it's technically easy to do, just attribute `lint` with `[option_group`]). We may want to explore adding an `alias` field to the `option` attribute and show the alias on the website along with its regular name. ## Test Plan I added new integration tests * I verified that the generated `options.md` is identical * Verified the default settings in the playground ![Screenshot from 2023-09-22 13-52-23](https://github.com/astral-sh/ruff/assets/1203881/7b4d9689-aa88-402e-9199-9c43c8d8cc2d)		2023-09-27 08:46:27 +02:00

README.md

flake8-to-ruff

Convert existing Flake8 configuration files (setup.cfg, tox.ini, or .flake8) for use with Ruff.

Generates a Ruff-compatible pyproject.toml section.

Installation and Usage

Installation

Available as flake8-to-ruff on PyPI:

pip install flake8-to-ruff

Usage

To run flake8-to-ruff:

flake8-to-ruff path/to/setup.cfg
flake8-to-ruff path/to/tox.ini
flake8-to-ruff path/to/.flake8

flake8-to-ruff will print the relevant pyproject.toml sections to standard output, like so:

[tool.ruff]
exclude = [
    '.svn',
    'CVS',
    '.bzr',
    '.hg',
    '.git',
    '__pycache__',
    '.tox',
    '.idea',
    '.mypy_cache',
    '.venv',
    'node_modules',
    '_state_machine.py',
    'test_fstring.py',
    'bad_coding2.py',
    'badsyntax_*.py',
]
select = [
    'A',
    'E',
    'F',
    'Q',
]
ignore = []

[tool.ruff.flake8-quotes]
inline-quotes = 'single'

[tool.ruff.pep8-naming]
ignore-names = [
    'foo',
    'bar',
]

Plugins

flake8-to-ruff will attempt to infer any activated plugins based on the settings provided in your configuration file.

For example, if your .flake8 file includes a docstring-convention property, flake8-to-ruff will enable the appropriate flake8-docstrings checks.

Alternatively, you can manually specify plugins on the command-line:

flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes

Limitations

Ruff only supports a subset of the Flake configuration options. flake8-to-ruff will warn on and ignore unsupported options in the .flake8 file (or equivalent). (Similarly, Ruff has a few configuration options that don't exist in Flake8.)
Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule codes from unsupported plugins. (See the documentation for the complete list of supported plugins.)
