What problem does it solve?

Translating natural language queries into ast-grep rules enables precise, AST-based code search and analysis, allowing developers to find patterns that text-based searches miss.

Core Features & Use Cases

Translate natural language requests into AST pattern rules to search large codebases.
Provide example code snippets and iterative rule refinement workflows for debugging.
Support multi-language codebases and complex structural queries (inside, has, precedes, follows) using YAML rules.

Quick Start

Create a simple rule targeting async functions with await and test it on a small sample file.

FAQPage Schema

How do I translate natural language queries into ast-grep rules for structural code search?▼

AST-based code search translates natural language queries into YAML rules to locate specific language constructs across large codebases. This allows developers to find structural patterns that text-based searches miss.

How do I search for specific code patterns using AST structure across multiple languages?▼

You can search for specific code patterns using AST structure by generating correctly formed YAML rules. These rules support complex structural queries like inside, has, precedes, and follows across multi-language codebases.

What is the best way to find specific language constructs in a large codebase that text search misses?▼

The best way to find specific language constructs is using AST-based code search. It translates natural language requests into structural pattern rules, enabling precise matching of code syntax and formatting.

Does ast-grep support multi-language structural queries for debugging complex code patterns?▼

Yes, ast-grep supports multi-language structural queries for debugging complex code patterns. It provides iterative rule refinement workflows and relies on the ast-grep CLI for validation and testing across different languages.

How do I debug and validate AST pattern rules generated from natural language?▼

To debug and validate AST pattern rules, use the ast-grep CLI on small sample files. The workflow involves iterative rule refinement, applying example code snippets to ensure the correctly formed YAML rules match the intended structure.
