Description

I noticed these when looking into something else, and they seemed easy enough to fix! For context, [A-z] matches punctuation between Z and a, making it overly broad and usually not what was intended. Instead, we should explicitly match [A-Za-z].

Checklist

  • Tests pass locally
  • uv run ruff check . passes (no unused imports or other lint errors)
  • uv tool run fawltydeps --check-unused --pyenv .venv passes (no unused dependencies)
  • Updated CHANGELOG.md with my changes, if notable (refer to Keep a Changelog conventions)

Summary by CodeRabbit

  • Bug Fixes
    • Improved text interpolation handling for word characters, including letters, numbers, and underscores.
    • Corrected leetspeak matching to exclude punctuation characters that were previously treated as letters.

`[A-z]` matches punctuation between `Z` and `a`, making it overly broad
and consequently the regex not doing its job of matching one or more
`3`s between other letters. Instead, explicitly match `[A-Za-z]`.
`A-z` matches punctuation between `Z` and `a`, making it overly broad.
Instead, explicitly match `A-Za-z` in addition to `0-9` and `_`.

📝 Walkthrough

Walkthrough

The change updates two regular expressions: UI interpolation patterns now use \w+, and the worker l33t-three pattern now matches only ASCII letters around sequences of 3.

Changes

Regex Corrections

Layer / File(s) Summary
Update regex character matching
osprey_ui/src/components/entities/RichDescription.tsx, osprey_worker/src/osprey/engine/stdlib/udfs/string.py
UI interpolation patterns use \w+. The worker l33t-three pattern restricts adjacent characters to ASCII letters.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: 🔵 Low · up to 5da46

The PR narrows overly broad letter matching, but the Python pattern still admits four non-ASCII characters under case-insensitive matching, so some inputs may continue to be classified as letters unexpectedly. This bounded correctness risk is mergeable with explicit owner follow-up.

In `@osprey_ui/src/components/entities/RichDescription.tsx`:
- Around line 10-11: Update RichDescription.tsx at lines 10-11 to preserve
interpolation of {feature_name} while ensuring [, \, ], ^, and ` are excluded
from identifier matching, and add regression coverage for these cases. Update
osprey_worker/src/osprey/engine/stdlib/udfs/string.py at line 238 so
StringClean(l33t=True) applies ASCII-only matching before boundary checks, then
extend test_strings.py coverage for punctuation boundaries and İ, ı, ſ, and K.

In `@osprey_worker/src/osprey/engine/stdlib/udfs/string.py`:
- Line 238: Restrict _L33T_THREES_SUB_PATTERN to ASCII-only case matching so
StringClean with l33t=True does not transform Unicode characters such as İ, ı,
ſ, or K; add the appropriate regex flag adjustment and a regression test
covering this behavior.
