Block-Based Syntax from Context-Free Grammars
summary
Kogi converts a context-free grammar into a working Google Blockly environment by preprocessing the grammar (it removes disambiguation rules and inlines chain rules), transforming productions into blocks, and emitting two artifacts: block definitions and a tiny web index that renders with Blockly. Applied to AWS resource grammar, Sonification, Pico and QL case studies, the generated editors let users drag/drop programs and execute them, though execution only shows final results and some UI/layout features and debugging remain unimplemented.
