Can't use other comments after "# fmt: ..." (like "# noqa: ...")

[HarrySky]

Describe the bug

Hi, I am experiencing an issue with # fmt: skip. If I put it next to long line - this line will be skipped (as expected):

log.debug("Long debug message ...........................................................")  # fmt: skip

But then flake8 will give me "E501 line too long" message, which I usually ignore with # noqa: E501 comment, but using it together with # fmt: skip is impossible, line below will be formatted:

log.debug("Long debug message, so we ignore flake8's E501 long line message")  # fmt: skip # noqa: E501

To Reproduce

1. Create file test.py:

from logging import getLogger
log = getLogger("log")
log.debug("Long debug message, so we ignore flake8's E501 long line message")  # fmt: skip # noqa: E501

2. Run Black on it
3. See that line was not skipped, but formatted

Expected behavior

I expected black to handle it just as flake8 and bandit, they for example detect everything properly if I put both # nosec # noqa comments on the same line.

Environment:

• Version: 21.5b0
• OS and Python version: Ubuntu 18.04, Python 3.8.8

Does this bug also happen on main?

Yes, online formatter link

The same is true with # noqa # fmt:skip (playground)

I'm having this issue aswell, with # fmt:skip isort:skip.

Any workaround? same happen to me 😞

Try this

# fmt: off
log.debug("Long debug message, so we ignore flake8's E501 long line message")  # noqa: E501
# fmt: on

Ik it works @seanbr76 , but seems too wordy to me.

[amirsalaar]

Try this

# fmt: off
log.debug("Long debug message, so we ignore flake8's E501 long line message")  # noqa: E501
# fmt: on

This only works for single cases. In my case, I have 7k lines in the code base that I am formatting which has # type: ignore and # noqa in some lines. The way to tackle fixing them in bulk is to use sed to prepend or append # fmt: skip to those lines.

Any progress on this?

Friendly inquiry about the status of this much-welcome (and needed!) feature... any progress?

This might be helpful: Pylint had similar issues a few years ago, and pylint-dev/pylint@daef49a and pylint-dev/pylint@b8f8c4a solved pylint-dev/pylint#2485 and others, allowing the pragma to begin or end with # or ; , so # noqa # pylint ... works as fine as # noqa; pylint ..., and lifting the "end of line" restriction, so # pylint ... # noqa works too!

Maybe their implementation can inspire a PR for Black?

Thanks @henriholopainen for the fix!
