AST-Grep Code Search

About

Empower your development workflow with the ability to search codebases based on structure rather than just text. This skill translates natural language requests into powerful ast-grep rules, allowing you to locate specific patterns like async functions without try-catch blocks or function calls with particular arguments. By leveraging AST patterns, it provides high precision for auditing large projects, identifying architectural violations, and performing complex code refactoring tasks that traditional text-based search tools cannot handle.

Key Features

• AST structure inspection and debugging tools for multiple programming languages
• Complex query construction using composite logic like all, any, and not
• Automated generation and validation of YAML-based ast-grep rules
• Structural pattern matching based on Abstract Syntax Tree (AST) nodes
• 1 GitHub stars
• Relational search capabilities including 'inside', 'has', and 'stopBy' constraints

Use Cases

• Locating specific language constructs or function calls with complex parameter requirements
• Auditing codebases for structural patterns like missing error handling in async code
• Performing high-precision code queries that exceed the capabilities of standard text search
