fzy_score

https://github.com/tachyurgy/fzy_score

A tiny, dependency-free fuzzy matcher that returns both a relevance score and the matched character positions (for highlighting) — the same algorithm family used by fzy, fzf, and fzf-for-js. Unlike Ruby's record-linkage fuzzy gems, fzy_score is built for command palettes, quick-open, autocomplete, and CLI pickers.
