What is a good way to separate concerns with CoffeeScript and Ruby on Rail's asset pipeline? -

tldr:

what can combine multiple coffeescript files 1 js file, in ror, under same anonymous function block?

long version:

i have few cs files loaded part of ror web app. i'm wondering: way separate concerns coffeescripts , ruby on rail 3.1's asset pipeline?

let's use following example code:

main.js.coffee

window.myapp = {} # escape coffeescript anonymous function block # (i anonymous function block because protects other  my_global_setting = "world!" $.click "#my_button" myapp.sayhello # (i use goog.bind here instead of using myapp. suggestions? fat arrow?) 

hello.js.coffee

myapp.sayhello = sayhello () ->   docomplicatedstuff()   alert("hello #{ my_global_setting }") 

complicated.js.coffee

docomplicatedstuff = () ->   # complicated algorithm, example   true 

i have assets directory structured following:

assets/   application.js   application/     # javascript gets used main application   secondary_page.js   secondary_page/     complicated.js.coffee     hello.js.coffee     main.js.coffee 

secondary.js

//= require secondary_page/main.js.coffee //= require secondary_page/complicated.js.coffee //= require secondary_page/hello.js.coffee 

i used compile files coffeescript part of build process, want use asset pipeline instead. i'm drinking ror 3.1 kool-aid! haha, though, asset pipeline looks awesome.

the problem i'm experiencing secondary.js looks following:

(function() {   // main.js ).call(this); (function() {   // complicated.js ).call(this); (function() {   // hello.js ).call(this); 

this prevents local variables being shared amongst entire code. my_global_setting , docomplicatedstuff aren't available sayhello.

so... should do? can't think of way without introducing own custom compilation step again.

this common question rails developers starting use coffeescript. see, example:

• "can't find variable" error rails 3.1 , coffeescript
• functions in controller.js.coffee
• how can use option "--bare" in rails 3.1 coffeescript?

solutions abound. simplest preface variable declarations want visible outside of particular file @, since this point window in outermost context of each file, , x points window.x when no local x defined.
