Provides programmatic access to AST-based tooling across Rust crates, Node.js NAPI, and Python bindings for parsing, searching, and rewriting code.
Invoke the AST API to parse code, search for patterns with metavariables, and apply a rewrite using YAML rule configs.
High-intent search queries and answers about installing and using this skill.
To search code structurally across multiple languages, you parse source code into an AST and use metavariable captures to match specific nodes. This enables precise structural querying and code analysis across different programming languages.
Automated code refactoring is applied by loading and running YAML rule configs programmatically. The system parses the AST, matches patterns defined in the YAML, and executes rewrites to transform the source code automatically.
Yes, ast-grep supports code analysis by providing programmatic AST tooling via Rust crates, Node.js NAPI, and Python bindings, allowing you to parse, search, and rewrite source code natively across these three environments.
Yes, during AST parsing you can extract matched node text and byte offsets. This functionality is useful for pinpointing exact code locations and extracting specific code segments matched by your structural search patterns.
The best way to programmatically rewrite source code using AST is by leveraging language bindings to parse code, match structural patterns with metavariables, and apply transformation rules. This ensures syntax-safe refactoring across supported languages.
