 Description   

Compiling a hello world program for Node.js works fine if using optimizations of :advanced or :simple, but if using :none or :whitespace then an error will be reported for either "goog undefined" or "goog.string" undefined respectively.

The program is shown here:

(ns pr.core)
(defn -main []
  (println "Hello World!"))
(set! *main-cli-fn* -main)

This program is in src/cljs/pr/core.cljs. The repl line used to compile is:

(cljs.closure/build "src/cljs" {:output-to "src/js/pr.js" :target :nodejs :pretty-print true :optimizations :none})

When compiled with optimizations of :none, the output is:

$ node src/js/pr.js 

/Users/pag/src/test/clj/pr/src/js/pr.js:1
(function (exports, require, module, __filename, __dirname) { goog.addDependen
                                                              ^
ReferenceError: goog is not defined

    at Module.runMain (module.js:492:10)
    at process.startup.processNextTick.process._tickCallback (node.js:244:9)

When running with optimizations of :whitespace the output is:

$ node src/js/pr.js 

/Users/pag/src/test/clj/pr/src/js/pr.js:493
goog.string.Unicode = {NBSP:"\u00a0"};
                    ^
TypeError: Cannot set property 'Unicode' of undefined

    at Function.Module._load (module.js:312:12)
    at Module.runMain (module.js:492:10)

When running with optimizations of either :simple or :advanced, the output is:

$ node src/js/pr.js 
Hello World!

I have included the two javascript output files that match the above errors.

This is a known bug. We need goog.require/provide to actually mean something to Node.js. I'm not sure how this can be made to work. I've been hoping for a patch for this since ClojureScript was first announced, but I haven't seen anything yet.
