Yes, if you need to parse Ruby code programmatically. The package is actively maintained, has no vulnerabilities, carries a permissive MIT license, and requires only Python 3.9+. Install friction is medium due to binary wheels, but prebuilt distributions are available for common platforms.

Before you install
- Requires Python 3.9 or later; binary wheels are available for common platforms but may require compilation on unsupported architectures.
- Medium install friction due to binary wheels for multiple platforms (macOS, Linux, Windows, ARM).
- Actively maintained with recent commits and no runtime dependencies, making setup straightforward once the wheel is available for your platform.

What it is and what it does
tree-sitter-ruby is a language binding that provides tree-sitter's incremental parsing engine for Ruby code. It ships as pre-built binary wheels for common platforms (macOS, Linux, Windows, ARM), reducing installation friction. The package contains a compiled grammar that can parse Ruby syntax into an abstract syntax tree, enabling tools to analyze, transform, or navigate Ruby code programmatically without invoking the Ruby interpreter.
You use it by importing the language module to access the grammar definition. This is useful for linters, code formatters, refactoring tools, or any application that needs to understand Ruby's structure. The grammar is maintained as part of the official tree-sitter project and references the Whitequark parser's AST format.
Use it for
- Building a Ruby linter or static analysis tool that needs to traverse code structure.
- Implementing a code formatter or refactoring tool for Ruby projects.
- Creating IDE features like symbol extraction, navigation, or code completion.
- Analyzing Ruby codebases to extract metrics, dependencies, or patterns.
- Integrating Ruby parsing into a polyglot code analysis platform.
