Next-generation HTML+ERB parsing ecosystem for smarter developer tooling.
Intelligently recognizes and navigates HTML structure within ERB templates, ensuring precise parsing across interleaved markup and Ruby code.
Powered by Prism, Ruby's new official default parser as of Ruby 3.4. Prism is designed to be error-tolerant and is adopted by major Ruby runtimes including CRuby, JRuby, TruffleRuby.
Designed to handle errors gracefully, it provides accurate results even when encountering syntax errors.
Parses input fast enough to update on every keystroke, ensuring real-time responsiveness in text editors and other tools.
Accurately preserves spacing and formatting in the parse result.
Works seamlessly with Language Server Protocols (LSP) for a better experience in modern editors.
Tracks precise locations down to individual character offsets for every node and token, enabling precise debugging, annotations, and diagnostics.
Native bindings for Ruby, JavaScript/TypeScript, and other high-level programming languages.
Future updates will expand beyond ERB through a unified parser and syntax tree architecture that maintains consistent APIs across different templating languages.
