## Summary This is another follow-up to #15726 and #15778, extending the quote-preserving behavior to f-strings and deleting the now-unused `Generator::quote` field. ## Details I also made one unrelated change to `rules/flynt/helpers.rs` to remove a `to_string` call for making a `Box<str>` and tweaked some arguments to some of the `Generator::unparse_f_string` methods to make the code easier to follow, in my opinion. Happy to revert especially the latter of these if needed. Unfortunately this still does not fix the issue in #9660, which appears to be more of an escaping issue than a quote-preservation issue. After #15726, the result is now `a = f'# {"".join([])}' if 1 else ""` instead of `a = f"# {''.join([])}" if 1 else ""` (single quotes on the outside now), but we still don't have the desired behavior of double quotes everywhere on Python 3.12+. I added a test for this but split it off into another branch since it ended up being unaddressed here, but my `dbg!` statements showed the correct preferred quotes going into [`UnicodeEscape::with_preferred_quote`](https://github.com/astral-sh/ruff/blob/main/crates/ruff_python_literal/src/escape.rs#L54). ## Test Plan Existing rule and `Generator` tests. --------- Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com> |
