  • Precision across 40+ languages: structural search, code transformation, and automated refactoring using sg CLI.
  • Security scanning and API migration: pattern-based checks and safe code transformations to enforce standards.
  • Real-world use: quickly locate and rewrite code patterns across large repos to standardize APIs and improve security posture.

Quick Start

Run a structural pattern search and apply a codemod across a codebase with sg.

Frequently Asked Questions about moai-tool-ast-grep

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I run structural code search and codemods across multiple programming languages?▼

Structural code search and codemods across 40+ languages are automated using AST pattern matching with the sg CLI, enabling precise structural search and safe code transformation in large repositories.

What is AST-based pattern matching for security scanning and API migration?▼

AST-based pattern matching uses abstract syntax trees to locate and rewrite code patterns, accelerating security checks and API migrations by applying language-agnostic structural rules to your codebase.

How do I automate large-scale code refactoring without breaking existing syntax?▼

Large-scale refactoring is automated using AST-based codemods that apply transformation rules to match and rewrite code structures safely, preserving syntax while standardizing APIs across large repos.

Can I use ast-grep for language-agnostic linting and code search in large codebases?▼

Yes, ast-grep supports language-agnostic linting and code search across 40+ languages, applying structural pattern matching to enforce security standards and locate code patterns in large codebases.

What's the best way to standardize APIs and improve security posture across a large codebase?▼

Standardizing APIs and improving security posture is best achieved by applying structural pattern-based checks and codemods to quickly locate and rewrite code patterns across large repositories.

Does ast-grep work as a plug-in tool for code transformation pipelines?▼

Ast-grep integrates as a plug-in tool through MoAI-ADK integration, supporting CLI tooling for structural pattern matching and transformation rules within automated code transformation pipelines.
