Requires #7769

Updates the CLI display for ruff check --fix to hint availability of unsafe fixes.

❯ ruff check example.py --select F601,T201 --diff --no-cache
No errors fixed (1 fix available with `--unsafe-fixes`).

Would fix 1 error (1 additional fix available with `--unsafe-fixes`).

This is all unchanged and pulled out of FixableStatistics.fmt because I don't think it makes sense to have it on the struct.

I don't think this belongs here, this is one specific message derived from this struct.

zanieb · 2023-10-06T15:24:58Z

I'd like integration test coverage for this but the messages are omitted there ~~for some reason~~; see #7838.

charliermarsh

I guess we should use the "Would be fixed" wording from below — just an oversight.

I think this still needs to be addressed but otherwise all good!

konstin · 2023-10-09T09:54:25Z

(1 additional fix available with --unsafe-fixes)

This to me sounds a lot like "please enable unsafe fixes to make this message go away". Maybe something like "(Excluding 1 unsafe fix)`?

zanieb · 2023-10-09T14:33:50Z

My qualm with "excluding" is it makes it sound like you've turned it off but it's just off by default. Hm..

One possibility is that we could change unsafe-fixes to be Optional throughout our settings and if it's not set we use these messages but if it's set to false explicitly we hide the suggestion?
