title: Getting auto-completion to work in an IDE using Coffeescript and external Javascript libraries such as jQuery
body: <p>I would like to ask how other more experienced Coffeescript developers are using their respective IDE's or editors with auto-complete when developing modular libraries and / or referencing external Javascript libraries (jQuery, jQuery UI, RequireJS, Handlebars, ...).</p>
  
  <p>As much as I've tried various IDE's and plug-ins for Coffeescript, none of these seem to support auto-completion when the project consists of several script files. For example: in Visual Studio I can add a commented directive such as <code>/// &lt;reference path="/js/jquery.js" /&gt;</code>. I'd need something similar for Coffeescript.</p>
  
  <p>I have tried following without success:</p>
  
  <ol>
  <li>Visual Studio with Web Workbench by Mindscape</li>
  <li>Netbeans with dstepanov's Coffeescript plug-in</li>
  <li>Aptana with the Coffeescript ruble</li>
  </ol>
  
  <p>Further, I am aware of Jetbrain's WebStorm 3.x support for Coffeescript, unfortunately, my evaluation period expired before I realized I'd need this feature - can anyone confirm that setting the Javascript / Coffeescript Usage Scope works as expected with auto-complete?</p>
  
  <p>So effectively what I am asking: is there an IDE or plug-in, commercial or otherwise,  enabling auto-complete for Coffeescript libraries spanning multiple files?</p>
