It lets you define patterns that match code structure\u2014not just text\u2014and then find, analyze, or transform matching code at scale. The package is a native Rust binding compiled to wheels, so it has no Python runtime dependencies and runs efficiently on modern Python versions.\n\nYou would use this when you need to perform structural code analysis or refactoring that text regex cannot handle: finding all calls to a deprecated function across a codebase, rewriting patterns to use a new API, or enforcing code style rules based on syntax tree shape. The API is programmatic, so you integrate it into scripts, linters, or CI pipelines rather than using a command-line tool.","worth_installing":"Yes, if you need structural code search or rewriting beyond regex. The package is actively maintained, has no security vulnerabilities, uses a permissive MIT license, and is well-distributed across platforms. Medium install friction is acceptable for a compiled tool. Start with the official API guide to confirm the pattern syntax and API surface fit your use case."},"id":"ast-grep-py","links":{"html":"https://skillfed.io/packages/ast-grep-py","md":"https://skillfed.io/packages/ast-grep-py.md","pypi":"https://pypi.org/project/ast-grep-py/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-07","license_spdx":null,"license_treatment":"permissive","name":"ast-grep-py","python_support":"supports_current","summary":"Structural Search and Rewrite code at large scale using precise AST pattern."},"popularity":{"monthly_downloads":1163264,"position":4281,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.45.1"}
