[FIXED] Ruff does not autofix line-too-long violation

Issue

I have a python project and I am configuring latest version of ruff for that project for linting and formating purpose. I have the below settings in my pyproject.toml file:

[tool.ruff]
select = ["E", "F", "W", "Q", "I"]

ignore = ["E203"]

# Allow autofix for all enabled rules (when `--fix`) is provided.
fixable = ["ALL"]
unfixable = []

# restrict Line length to 99
line-length = 99

The ruff check command with autofix feature (--fix) of ruff identifies that the lines are long with E501 errors, but it does not format that code to wrap to next line to maintain the line-length restriction. Is there something I need to enable or do to ensure that ruff fixes this? Or is this not possible in ruff currently? Please help.

I tried going through the documentation to find anything, but I am clueless what to do here.

Solution

It seems like Ruff has released Ruff Python Formatter as part of v0.0.289 and is currently in alpha state - https://github.com/astral-sh/ruff/blob/main/crates/ruff_python_formatter/README.md

We are currently using v0.0.280 which does not have this feature so we used a combination of Black and Ruff as per our project requirements.
