I recently discovered the existence of source maps in chrome via source debugging in the haxe language. It allows to debug generated javascript inside the chrome browser while seeing the bug reason in the original source code.
Has anyone written a source map generator for coffeescript / Is coffeescript source mappable ?
It would help debug the javascript generated by coffeescript.
This has long been an active issue on the CoffeeScript project (indeed, it predates the source map standard). However, no (complete) CoffeeScript source map generator exists yet. For discussion, see https://github.com/jashkenas/coffee-script/issues/558
Source map support is also one of the goals of the “CoffeeScript Redux” compiler that was recently funded on Kickstarter (see http://www.kickstarter.com/projects/michaelficarra/make-a-better-coffeescript-compiler). That project has just begun; you can watch it at https://github.com/michaelficarra/CoffeeScriptRedux
