AST-based structural code search matches code patterns based on Abstract Syntax Tree structure rather than raw text. This enables precise semantic matching, allowing you to find function calls or variable assignments regardless of formatting or variable names.

Automate API migration and refactor deprecated calls by running codemod operations and semantic code transformations. This applies structural pattern matching to automatically update all instances of an outdated API call across your entire project.

Yes, you can use structural code search for security scanning and vulnerability detection. It identifies risks like SQL injection by applying predefined or custom rules to parse and analyze code patterns across your codebase.

The best way to find all console.log statements is to perform structural code search within the target directory. By matching the AST node structure of the function call, you can accurately locate every instance without false positives from comments.

Yes, ast-grep supports over 40 programming languages for CI/CD pipeline integration. It enforces coding standards and executes codemods across polyglot codebases by applying language-specific Abstract Syntax Tree parsing rules.

You should not use AST structural search when simple text matching suffices, as setting up custom rules for trivial pattern matching adds unnecessary overhead. It is designed for complex semantic analysis, API migration, and deep refactoring tasks.
