AST-Grep Code Search

Acerca de

Unlock the power of structural code search with ast-grep, a tool that identifies code patterns based on their syntactic structure rather than just text. This skill enables developers to perform precise queries—such as finding async functions without error handling—by translating natural language requests into sophisticated AST-based rules. It is particularly useful for large-scale code audits, refactoring, and locating specific language constructs where traditional string-based search falls short.

Características Principales

• Enables complex filtering using composite logic like 'all', 'any', and 'not'
• Supports relational matching using 'inside', 'has', and 'precedes' operators
• Facilitates both quick inline pattern searches and reusable YAML-based rules
• Translates natural language queries into structural AST search rules
• Provides AST inspection tools to identify specific node kinds and structures

• Finding all async functions that perform await operations without try-catch blocks
• Locating specific function calls with particular parameters within class methods
• Searching for structural anti-patterns or deprecated code constructs across a project
