init-hook and setup.cfg

[rdehouss]

Hello,

I'm using the init-hook to tell pylint where to find my librairies and it works fine in .pylintrc but it's not working when I move the content of .pylintrc in the setup.cfg file

Steps to reproduce

1. Checkout https://github.com/rdehouss/pylint-issue-init-hook-setup-cfg
2. Install pylint with pipenv (pipenv install --dev)
3. Execute find . -name "*.py" -not -path '*/\.*' -exec pipenv run pylint --rcfile=.pylintrc '{}' + => OK
4. Execute find . -name "*.py" -not -path '*/\.*' -exec pipenv run pylint --rcfile=setup.cfg '{}' + => NOK

Please note that the disable=missing-docstring works well since when I remove it, I get

find . -name "*.py" -not -path '*/\.*' -exec pipenv run pylint --rcfile=setup.cfg '{}' +
************* Module src.hello_world
src/hello_world.py:1:0: C0111: Missing module docstring (missing-docstring)
src/hello_world.py:1:0: E0401: Unable to import 'libs.hello_world' (import-error)
************* Module src.libs.hello_world
src/libs/hello_world.py:1:0: C0111: Missing module docstring (missing-docstring)
src/libs/hello_world.py:1:0: C0111: Missing function docstring (missing-docstring)

Expected behavior

init-hook works like when it is in .pylintrc

pylint --version output

Hi, thanks for the report. Currently pylint does not support setup.cfg, anything else other than the sanctioned format in pylintrc is not going to be supported due to various assumptions of the config parser we use. This might change in the future with #617 but can't promise an exact date when that is going to be supported.

This is still not going to be changed?

We support pylintrc, pyproject.toml, and setup.cfg check the doc here: https://pylint.readthedocs.io/en/latest/user_guide/configuration/index.html
