I want to write a Google Chrome extension, using ClojureScript. With ClojureScript I can use all the Google Closure libs, but afaik access to the Chrome browser is not included in those libs. So I want to wrap all the Chrome stuff in my own JavaScript lib.
So far I tried creating my own jar that has a single JavaScript file that just creates a Foo object and exports the constructor. I'v added this jar to the lib directory of the ClojureScript compiler (which also has for example goog.jar), but so far without luck:

Has anyone tried this before?
Take a look at this post from Luke Vanderhart: "Using JavaScript libraries in ClojureScript"
http://lukevanderhart.com/2011/09/30/using-javascript-and-clojurescript.html
Also, this video from Kevin Lynagh: "Extending JavaScript Libraries from ClojureScript"
If I remember Rich Hickeys talk correctly the whole program optimization of the closure compiler needs any library code to adhere to certain coding conventions. I think he also said something of JQuery not doing this but Dojo doing this. I never did this but you might find some useful information here
