Code Transformation
Problem
Automated rewrites (migrations, codemods) must preserve everything they do not intend to change.
Why tree-sitter.zig helps
Match ranges are exact, unaffected regions reuse their subtrees, and reparsing the result verifies the output parses cleanly.
API
Query matches → text edits → Parser.parse → hasError check on the result.
Architecture
text
Match → compute edits → apply → reparse → verify no errors
