CoffeeScript source maps

I just want to note that the new CoffeeScript compiler is using ESCodeGen as a backend, which is doing the source map heavy lifting. Anyone writing a compiler which targets JS can use ESCodeGen as a backend and get source maps pretty much for free. Awesome news all around!<p><a href="https://github.com/Constellation/escodegen" rel="nofollow">https://github.com/Constellation/escodegen</a><p>Note: I do not want it to seem like I want to take anything away from Michael Ficarra and the new CoffeeScript compiler. He also wrote the code to integrate source maps with ESCodeGen, but it is something that many projects will be able to take advantage of, not just CoffeeScript.<p>In other source map news, if anyone hasn't seen it yet, UglifyJS v2 now supports source maps: <a href="http://lisperator.net/blog/uglifyjs-v2-news/" rel="nofollow">http://lisperator.net/blog/uglifyjs-v2-news/</a><p>Source map support is on the way for Firefox's debugger as well: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=771597" rel="nofollow">https://bugzilla.mozilla.org/show_bug.cgi?id=771597</a>

This is possibly the most important thing to happen to my frontend development workflow all year. Amazing contribution. Thank you.

Is CoffeeScriptRedux actually ready for production use? From my read of <a href="https://github.com/michaelficarra/CoffeeScriptRedux/wiki/Progress" rel="nofollow">https://github.com/michaelficarra/CoffeeScriptRedux/wiki/Pro...</a> there are many features missing.

I would LOVE to see source maps implemented into Rails CS compilation. Any idea how to do it/when will this be added to rails?

Will this affect debugging under node.js, or just browsers? (Googling doesn't seem to make this clear.)

As the article mentions, the next big step will be access to the debug console.
