Glicol: A Graph-Oriented Live Coding Language Developed With Rust, WebAssembly And AudioWorklet
summary
Glicol is a live‑coding language and Rust audio engine compiled to WebAssembly and run in an AudioWorklet, able to run in-browser, on embedded Bela boards, or as a JS lib. It represents audio as DAGs, parses with Pest, uses dasp_graph nodes, and applies longest common subsequence node diffing to update graphs with minimal changes. A phase-preserving preprocessing keeps oscillator state across edits, SharedArrayBuffer-based comms move code/samples to the audio thread, and syntax errors fall back to the previous running graph.
