AST-based structural search replaces brittle text searches by matching code structures, enabling precise discovery across languages.

To search for nested code patterns across multiple languages, ast-grep translates natural language queries into structural AST rules. It matches code constructs based on syntax trees rather than plain text, using Tree-sitter grammars for precise multi-language discovery.
Structural code search uses abstract syntax trees to match code constructs instead of raw strings. You need it when text search is too brittle, such as when locating specific language constructs, nested patterns, or code anti-patterns that require understanding syntax structure.
Yes, you can use metavariables in a YAML rule object to capture and match specific code patterns. ast-grep supports YAML rules with fields like kind, pattern, inside, has, and composite rules to define complex structural constraints.
You can control traversal depth when matching complex AST structures by using the stopBy field in your YAML rule. This allows precise traversal control for composite rules, ensuring structural searches halt at the correct nested pattern level.
Yes, ast-grep works with Tree-sitter grammars to provide language-agnostic code analysis. It applies to multi-language codebases by translating structural queries into rules that leverage Tree-sitter syntax trees for accurate pattern matching.
The best way to locate specific code constructs and anti-patterns is using AST-powered structural search. By translating queries into ast-grep YAML rules, you can precisely discover nested patterns and complex structures across multi-language codebases.
