What went wrong

I'm using ruff linter and fixer for python files.

I have a project where the linter detects errors and the fixer doesn't.

I suspect that the difference comes from the fact that the path to the file provided for --stdin-filename is different. It's an absolute path for the linter whereas it's a relative one for the fixer.

Here are the commands that ALE uses to run the linter and fixer (copied and simplified from ALEInfo and simplified):

$ #linter
$ cd '/path/to/project/lib' && '/path/to/project/.venv/bin/ruff' check -q --no-fix --output-format json-lines --stdin-filename '/path/to/project/lib/file.py' - < '/tmp/vsQmWbc/15/file.py'
$ #fixer
$ cd '/path/to/project/lib' && '/path/to/project/.venv/bin/ruff' check --stdin-filename 'lib/file.py' --fix - < '/tmp/vsQmWbc/12/file.py'

Additional note : in our project, the structure of files may be a bit specific. We have 2 packages, each with its own pyproject.toml file. The configuration file for ruff is at the root of the project.

project
└─ruff.toml
└─lib
│   └─pyproject.toml
│   └─file.py
└─cli
    └─pyproject.toml
    └─file.py

It seems like given the path of the file (ie. relative), ruff doesn't use its configuration file. Also, I think the path is wrong: after the cd the path should actually be file.py, not lib/file.py.
