About ast-grep

ast-grep is a fast CLI tool, written in Rust, for structural code search, linting, and rewriting across many languages. Instead of matching text like grep, it matches abstract-syntax-tree patterns, making it well suited to large-scale, syntax-aware refactors and custom lint rules. It targets developers and platform teams doing systematic codebase changes.
