What is Tree-sitter and why use it in Go?

Tree-sitter's an incremental parser for code — fast, accurate trees for highlighting/LSP. In Go, pure impl means no CGO bloat, static bins everywhere.

Can pure Go Tree-sitter parse my favorite language?

Starts with 11 (JS, Python, Rust etc.); grammars generated from JSON specs. Add yours — open source.

Does replacing regex with Tree-sitter speed up my tools?

Yes — 2-5x on benchmarks, precise on complex nests. Static bonus: smaller, safer deploys.
