tool.flake8.known-modules namespace issues

[jonyscathe]

Hi,

Just moved over to usingflake8-pyproject and [tool.flake8.known-modules] looks like a great addition for that.

Did take me a while to get it working though, due to the use of a namespace in the project.

My previous known-modules from setup.cfg was of the form:

known-modules = my_namespace.my_project:[my_namespace.my_project, packaging, dunamai]

I attempted to change to this but was getting a whole lot of I900s flagged:

[tool.flake8.known-modules]
my_namespace.my_project = [
    'my_namespace.my_project',
    'packaging',
    'dunamai',
]

Eventually I worked out that I could change to:

[tool.flake8.known-modules]
'my_namespace.my_project' = [
    'my_namespace.my_project',
    'packaging',
    'dunamai',
]

It looks a little gross with the key in quotes but it at least works. I'm not sure there is any way around this? If not, might be worth adding a short note to the documentation as otherwise this could confuse a few people.

Maybe @nyuszika7h can say more about this, I'm not using pyproject as for now.

Yeah I think you have to add the quotes, otherwise TOML treats it as a nested key. Unless we add some hack in flake8-requirements itself to map nested keys back to a flat key but I don’t think it’s worth adding such a hack.
