Meet ast-grep: a Rust-based tool for code searching, linting, rewriting using AST

• ast-grep

  32 5,863 9.9 Rust

  ⚡A CLI tool for code structural search, lint and rewriting. Written in Rust

  

Hey folks! I'm writing a tool like a hybrid of grep, eslint and codemod, for almost all tree-sitter compatile languages. The front page is https://ast-grep.github.io/.

• comby

  3 2,265 0.0 OCaml

  A code rewrite tool for structural search and replace that supports ~every language.

  

How does it compare to https://github.com/comby-tools/comby, which can work on languages it doesnt even have grammars for (to a degree)

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• weggli

  13 2,266 3.3 Rust

  weggli is a fast and robust semantic search tool for C and C++ codebases. It is designed to help security researchers identify interesting functionality in large codebases.

  

I use weggli quite frequently for security analysis. Are there any plans for friendly competition in terms of equivalent features (not:, subexpressions, etc.).

  Rust / Wasm framework for creating reliable and efficient web applications

  

Thanks for your interest! I hoped ast-grep can help you find (potentially bad) code and do some basic refactoring. For open-source maintainers, it can help them to ship breaking changes more easily. yew.rs is changing their use_effect API and ast-grep helped for users to migrate. https://yew.rs/docs/next/migration-guides/yew/from-0\_20\_0-to-next

• eslint

  1 5 4.1 TypeScript
  

This is an example to run an eslint rule using ast-grep. https://github.com/ast-grep/eslint/blob/main/rules/array-callback-return.yml

• helix

  405 30,031 9.9 Rust

  A post-modern modal text editor.

  

Perfect or not, it’s been nice to see so many languages standardize with LSPs and tree-sitter lately. I like Helix quite a bit, which takes advantage of that (and the AST-based navigation is neat), and I was actually just recently wondering if there was a tree-sitter based linter I could use on anything, so this is perfect timing.
