F403, F405 and wildcard import

[robtaylor]

Hi, I've been working a lot with Amaranth recently. As it's really a python embedded DSL, the recommendation is to use from amaranth import * to bring in the full DSL. It uses all and manages its api surface.

Obviously I can ignore F403 and F405, but then i may miss mistakes unrelated to the DSL.

Would it be possible for ruff to import all when wildcard importing so I don't need F405? It could error if that is not defined.

Hey there, if I understand your question correctly, the answer is no as Ruff cannot currently resolve symbols from other files. Here's an issue that tracks the feature: #7447

Oh excellent, thank you!

I have a similar problem (should I start a new discussion instead?).
I typically avoid star import, but I use "from constants import *" in most files, and I don't think there are any good alternative.
Is it somehow possible to make ruff ignore F405 if the variable name match a certain pattern?
It would not be fail-safe, but I'd be okay to simply ignore any F405 where the name matches "^[A-Z][A-Z0-9_]*$", but report for any other name. (And it don't require multi-file analysis.)

I don't believe there's any existing mechanism for ignoring specific variable names, and I'm not sure that we'd want to add a configuration option here.

As workarounds, I would typically either just accept a big block of explicit imports or possibly do something like:

import constants as c

area = c.PI * r**2
