ast-grep-find

AST-based code search uses abstract syntax tree matching to find structural patterns like function definitions, imports, and class declarations while ignoring string literals and comments. This ensures precise results by understanding code semantics rather than text matching.

Yes, AST-grep enables cross-file variable and function renaming with correct scope awareness. It uses syntax patterns to identify all references and replaces them safely, respecting language semantics across your entire codebase.

AST-grep supports multiple languages including Python, JavaScript, and others through language-specific syntax tree analysis. You specify the target language with the --language parameter to ensure accurate structural matching for that language's grammar.

Use the --dry-run parameter to preview all proposed replacements without modifying files. This lets you review matches and refactoring results safely before committing changes to your codebase.

Yes, use --path to target specific directories and --glob to filter by file patterns. These parameters let you narrow searches to relevant portions of your codebase before running syntax-aware pattern matches.
