What problem does it solve?

ast-grep matches code by AST structure, not text, enabling precise searches and safe rewrites across languages.

Core Features & Use Cases

  • AST-based pattern matching with metavariables
  • Language-specific patterns for JavaScript/TypeScript, Python, Go, and Rust
  • JSON output options and YAML rules for complex matching

Quick Start

Run sg with a language flag to search for an AST pattern in your codebase, for example sg run -p 'use$HOOK($$$)' -l typescript src/.
