AST-driven code search, rewrite, and rule testing can be verbose and error-prone when done manually. This skill provides a cohesive CLI to locate patterns, apply safe transformations, and validate rules against codebases.
Run a sample search with a pattern to locate matches in your codebase.

AST pattern matching for code search and refactoring uses YAML-defined rules to locate and rewrite code structures safely. This approach leverages abstract syntax trees to automate transformations across JavaScript and TypeScript codebases via a CLI.
Validating and testing custom code rewrite rules uses snapshot-based validation to ensure rule stability. You define test cases in your project configuration to scan the codebase and verify that pattern matches and transformations produce expected results.
Yes, you can use YAML rules to search JavaScript and TypeScript code effectively. The system applies these YAML-defined rules through the ast-grep CLI to execute structured abstract syntax tree searches across your project files.
Organizing AST code search rules in a project uses an sgconfig.yml file to define and manage rule directories. This configuration establishes a cohesive project setup that enables the CLI to locate and apply your custom pattern-matching rules accurately.
Manual AST-driven code rewrites fail when refactoring large codebases because they are verbose and error-prone without a cohesive CLI. Automating searches and applying safe transformations through snapshot validation prevents structural errors during execution.
