[`pyupgrade`] Fix parsing named Unicode escape sequences (`UP032`) by phongddo · Pull Request #21901 · astral-sh/ruff

phongddo · 2025-12-10T18:15:35Z

Summary

Fixes #19771

Fixes incorrect parsing of Unicode named escape sequences like Hey \N{snowman} in FormatString, which were being incorrectly split into separate literal and field parts instead of being treated as a single literal unit.

Problem

The FormatString parser incorrectly handles Unicode named escape sequences:

Current: Hey \N{snowman} is parsed into 2 parts Literal("Hey \N") & Field("snowman")
Expected: Hey \N{snowman} should be parsed into 1 part Literal("Hey \N{snowman}")

This affects f-string conversion rules when fixing UP032 that rely on proper format string parsing.

Solution

I modified parse_literal to detect and handle Unicode named escape sequences before parsing single characters:

Introduced a flag to track when a backslash is "available" to escape something.
When the flag is true, and the text starts with N{, try to parse the complete Unicode escape sequence as one unit, and set the flag to false after parsing successfully.
Set the flag to false when the backslash is already consumed.

Manual Verification

"\N{angle}AOB = {angle}°".format(angle=180)

Result

 def foo():
-    "\N{angle}AOB = {angle}°".format(angle=180)
+    f"\N{angle}AOB = {180}°"

Would fix 1 error.

"\N{snowman} {snowman}".format(snowman=1)

Result

 def foo():
-    "\N{snowman} {snowman}".format(snowman=1)
+    f"\N{snowman} {1}"

Would fix 1 error.

"\\N{snowman} {snowman}".format(snowman=1)

Result

 def foo():
-    "\\N{snowman} {snowman}".format(snowman=1)
+    f"\\N{1} {1}"

Would fix 1 error.

Test Plan

Added test cases (happy case, invalid case, edge case) for FormatString when parsing Unicode escape sequence.
Updated snapshots.

Thanks! This makes sense to me, I just had a couple of small suggestions about the tests.

I took a closer look at this code today, and I'm feeling much less wary than in #19774 (review). Our parser will have already flagged weird invalid cases like these that I brought up last time:

"\N{{angle}}".format(angle="angle")
"\N{LATIN {SMALL} LETTER A}"

So we only need to handle valid cases, which this PR seems to do in a nice way. I also ran the fuzzer for a little while, just in case.

Hey @ntBre 👋 just in case you missed the updates on this PR. I've addressed your comments about the tests. Please take a look when you have a moment and let me know if there's anything else I should adjust 🙏

ntBre

Thank you!

This looks good to go, just one small test comment update, and I think I preferred your old tests (to avoid adding a dev-dependency to this crate). Sorry for the flip-flop and the delay.

This reverts commit 10aeb6d.

This reverts commit 99a52eb.
