Lrama Corral is a visual editor for Lrama grammar files (.y files) that runs entirely in the browser using Ruby Wasm. It provides real-time parsing, grammar analysis with First/Follow sets and conflict detection, and interactive diagrams for syntax visualization and LALR state machine. The tool features a Monaco Editor with Yacc/Bison syntax highlighting, dark mode support, and file operations, making it ideal for developers working with parser grammars who need an accessible, no-installation-required tool for creating and debugging LALR(1) grammars.
