> ideally will generate much of the Javascript Just to play devil's advocate, but with any compiled-to-JS language, you're right back to where GWT is with superdevmode: stuck in the browser's debugger. My hope is that with enough "compiled-to-JS" languages (Coffeescript, etc.) becoming popular that browser vendors will build a standard debugging wire protocol, much like the JVM's, which would allow IDE-based debugging of sourcemapped JS code. This project is taking that on for Eclipse, which is a huge challenge and I'm very impressed that they're even attempting it: https://github.com/sdbg/sdbg https://github.com/sdbg/sdbg Given you use IntelliJ, which typically has a much faster turn around on supporting bleeding-edge browser/etc. integration, I would actually except them to get it first.
