Structural code search based on AST patterns to find relationships between code elements, not just textual matches.
Create a simple rule (e.g., kind: function_declaration with a has: pattern) and run ast-grep against your codebase to observe matches.

Structural code pattern searches use ast-grep to perform Abstract Syntax Tree (AST) based matching over source code, detecting specific patterns and refactoring opportunities rather than relying on textual matches.
You can capture specific code nodes during AST-based refactoring by using ast-grep's metavariables. Metavariables allow you to capture specific elements within matched patterns for deep analysis and targeted refactoring across your codebase.
Yes, ast-grep supports atomic, relational, and composite rules for code search to specify precise queries. These rule types allow you to identify complex relationships between code elements and find specific structural patterns across large codebases.
When structural search queries are not working, the best way to debug is by using ast-grep's built-in debugging tools. You can use the --stdin option for quick testing and the --debug-query command to fine-tune your AST pattern matches.
AST pattern matching differs from regular text search by analyzing the structural relationships between code elements rather than matching exact strings. This structural approach to static analysis finds code patterns that text searches would miss due to formatting variations.
No, you do not need composite rules to find function declarations with specific patterns. You can start with a simple atomic rule, such as specifying kind: function_declaration with a has: pattern, and run it against your codebase to observe matches.
