Efficiently locate and refactor code by leveraging AST patterns instead of brittle text searches, reducing false positives and manual effort.
Install ast-grep and run a pattern search on your codebase to begin discovering matches.

AST-based code search finds structural code patterns instead of brittle text matches, reducing false positives. You write AST pattern rules with metavariables to locate exact code structures across a repository for safe code discovery.
Automated refactoring across multi-language repositories is done using AST pattern rules with metavariables for safe code transformations. This structural approach rewrites code accurately without relying on error-prone text replacements.
Structural linting applies AST pattern matching to enforce code rules during static analysis. By analyzing the syntax tree, it identifies non-compliant structures across large codebases more reliably than regex-based linting.
Yes, you can constrain AST search results using relational pattern matching. Rules can specify structural constraints like inside, has, or precedes to filter matches based on their relationship to surrounding code.
You need a Rust-based binary or a prebuilt release to run AST-based code search and refactoring. Once installed, you can execute pattern searches directly on your multi-language codebase from the CLI.
Debug AST pattern matching rules using built-in debugging aids to visualize AST and CST structures. Inspecting the concrete syntax tree helps you verify that your metavariables and patterns align with the actual code structure.
