Bespin, Skywriter, Ace - The Past, Present and Future of online Code Editing
summary
Ace is a fast, embeddable web code editor that runs in old browsers, uses a DOM renderer that only renders visible lines, and offloads heavy work to web workers so large files never freeze the UI. Demonstrated is a live CoffeeScript preview that compiles in a worker and updates a read‑only JS pane without blocking typing. Project stats: about 230 pull requests from contributors and 17 language modes, plus features like code folding and vi keybindings.
