Is there a way to tell ruff to ignore comments?

[xeon826]

Since Ruff is made to work in unison with Black, and Black doesn't reformat comments that exceed the line length, is there a way to tell Ruff to ignore these?

@xeon826 if you're using Black to enforce your line length I'd just recommend disabling E501 e.g. https://github.com/PrefectHQ/prefect/blob/a3a2f84ba17b8a4469f29fc2a2bfc6dbffd40ed0/.ruff.toml#L1-L2

[xeon826]

I'm using ruff-pre-commit and I added that to its ignore as a workaround but I'm also using ruff as a linting tool and it gives me the diagnostic if comments exceed the line length, I feel like --ignore-comments would be a useful feature.

Why don't you put it in your Ruff configuration so it is always applied?

Note this is also a duplicate of #4429 and #4595

We cover this in the FAQ too.

[xeon826]

I use it to check for line length as a linting tool in my environment, if I ignored E501 all together, I wouldn't get that behavior.

pyproject.toml

[tool.autoflake]
remove-all-unused-imports = true
in-place = true
expand-star-imports = true
remove-unused-variables = true

[tool.black]
line-length = 88
skip-string-normalization = true
skip-magic-trailing-comma = true
preview = true
target-version = ['py39']

[tool.isort]
profile = 'black'

[tool.ruff]
line-length = 88
target-version = 'py39'
fix = true

[tool.flake8]
max-line-length = 88

[tool.vulture]
exclude = ['venv', 'pod_v3', 'frontend-ops', 'labelbox', 'compute_v2']
paths = ['webapp']
min_confidence = 60
ignore_names = ["visit_*", "do_*"]
sort_by_size = true

Black doesn't reformat comments that exceed the line length

@xeon826, are you referring to lines containing only a comment? Black has often rearranged my # type: ignore and # noqa comments, much to my chagrin, especially because I always include descriptive messages about why I'm ignoring something on that line.

[tylerlaprade]

As an aside, @xeon826, you can 100% replace the functionality of autoflake and isort with ruff, including all the customization in your pyproject.toml. This is 99% likely to be true of flake8 as well, unless you are enabling some esoteric extension rules outside of your pyproject.toml

[xeon826]

@tylerlaprade Lines that are only a comment, yes. I'd remove autoflake but ruff doesn't include the expand-star-imports feature

Since this is a duplicate and there's a workaround I'm going to close this for bookkeeping purposes. Thanks for raising!

i think so too. --ignore-comments would be a useful feature, sometimes we want to write code like this.

demo_code = generate_anything()  # some comments and this line length exceed 79 that i config.

--line-length <LINE_LENGTH> Set the line-length

Don't we have a solution for this yet?
