Alternate quotes for strings inside f-strings in preview

[MichaReiser]

Summary

This PR changes how quotes are selected for f-strings and nested string literals when preview mode is on.

For the outer f-string: The logic is the same as for any other strings, except that we only count the quotes inside literal parts. This is different from before where choose_quotes analyzed the entire f-string, including expressions.

The rules for inner f-strings are:

• If the outer f-string is a triple quoted string: Prefer the configured quote style
• If the outer f-string is single quoted: Prefer the opposite quote style (alternate the quote styles).

f"{'inner'}"

# Before
f"{"inner"}"

The only exception to the above rule is when targeting <Py312 and the f-string contains a debug-expression that itself contains quotes:

f'{a + "b"=}' # Can't change the quotes here

In this case, changing the quotes is unsafe because the debug expression will retain its existing quotes. That's why the implementation must preserve the outer quotes as is. Changing the outer quotes is fine when targeting Py312+.

f"{a + "b"=}"

The advantage of limiting the pre-312 behavior to only debug expressions is that an upgrade of the target version to 312 should result in a very small diff considering that debug expressions containing quotes should be rare.

Fixes #13237
Fixes #11056

Considerations

This new style no longer optimizes for the fewest "foreign" quotes in total. E.g. it changes

return f'#{data["node"]["number"]} {component_str}{data["node"]["title"]}'

to

return f"#{data['node']['number']} {component_str}{data['node']['title']}"

where the total preferred quotes count is 2, but it uses 8 single quotes.

Test Plan

• Added tests
• Reviewed the snapshot changes
• Reviewed the ecosystem changes

Review

The most useful for review is if you can think of more cursed f-string examples where the above approach might produce invalid f-strings or weird looking quote selections.

Both from_part and merge are also needed for implicit string formatting. We get good reuse :)

[MichaReiser]

This not only fixes the issue where Ruff failed to change the quotes in Py312+ but now also ensures that f-strings use the preferred quote styles if nested literals uses the other quotes

[dhruvmanila]

This might make rustfmt mad so might want to do this locally

Suggested change

	if fstring
	.elements
	.iter()
	.filter_map(FStringElement::as_expression)
	.any(|expression| {
	if fstring
	.elements
	.expressions()
	.any(|expression| {

[MichaReiser]

Oh it's on elements. I always try to call it on the fstring

[dhruvmanila]

It's interesting that as a side effect we'll start fixing certain code that would raise a syntax error pre-3.12.

[dhruvmanila]

Is this correct? The outer single quotes got formatted to use double quotes even though the expression has a double quoted string, thus not using alternate quote style.

[MichaReiser]

Yes. The idea is that we use the same quote selection criteria as everywhere else and we keep using double quotes to avoid unnecessary escaping the single quote

[dhruvmanila]

This is great! I really like the ecosystem changes as well. I played around with random f-string with quotes but couldn't really find anything unexpected.

[MichaReiser]

I'll do another review of my own changes tomorrow and then plan to land this.
