Ignore unused imports

[bdice]

In flake8, users can ignore F401 to avoid warning about unused imports. I tried cython-lint --ignore F401 but it seems to do nothing. From the source of cython-lint, it doesn't seem like there is a way to disable this check right now.

cython-lint/cython_lint/cython_lint.py

Line 744 in 0afd546

f'\'{_import[0]}\' imported but unused',

Ideally users would be able to ignore import and cimport statements separately -- in the cases I'm considering, I'd like to detect unused cimport statements but ignore unused import statements.

good idea - interested in submitting a pr?

It seems like cython-lint might need a way to ignore violations raised by cython-lint itself (as opposed to pycodestyle) which seems like it could be a lot of scope. That would require naming a code for existing violations, unless you want to do something like add a flag for every violation (e.g. --ignore-unused-imports, --ignore-unused-cimports). What do you think is the best course of action?

either sounds good!

just fyi for now I'd expect that # no-cython-lint would work, but a cli argument to turn off this globally sounds useful
