ast-grep provides syntax-aware code search and refactoring, allowing you to find and modify code by structure rather than plain text.
Find all class definitions in TypeScript: sg -p 'class $NAME { $$ }' -l typescript .

Structural code search locates functions, classes, imports, and other syntax patterns by their structure rather than plain text. ast-grep uses pattern syntax to match code across JavaScript, TypeScript, Python, Ruby, Go, Rust, and other languages, returning precise results that text search cannot.
Yes. Language-aware refactoring rewrites matching code structures—renaming, moving, adjusting imports—across your entire codebase. ast-grep handles multi-language environments and monorepos, applying consistent changes without breaking syntax.
Define a pattern using ast-grep's syntax to describe the code structure you want to find, then apply automated or interactive rewrites. This catches variations text search misses and ensures replacements respect language grammar.
Yes. ast-grep supports cross-language pattern detection in monorepos, letting you search and refactor TypeScript, Python, JavaScript, and other languages within a single codebase using language-specific syntax rules.
ast-grep outputs JSON, making results easy to pipe into other tools for analysis, reporting, or automation. This enables integration into CI/CD pipelines and custom workflows.
ast-grep uses pattern syntax that describes code structure declaratively—for example, `class $NAME { $$ }` matches any class. Patterns use placeholders and wildcards aligned with the language's grammar, not regex or text matching.
