Currently working through this tutorial on using Backbone.js with coffeescript.
Leveraging the following index.html file:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>CoffeeScript, Meet Backbone.js: Part N</title>
<link rel="stylesheet" href="style.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/json2/20110223/json2.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/underscore.js/1.1.6/underscore-min.js"></script>
<script src="http://ajax.cdnjs.com/ajax/libs/backbone.js/0.3.3/backbone-min.js"></script>
<script type="text/javascript" src="./index.js"></script>
</head>
<body>
<header>
<h1>CoffeeScript, Meet Backbone.js: Part 1</h1>
</header>
</body>
</html>
which loads an index.js file after loading Backbone, jQuery, etc from a cdn. Hoping to work within a script.coffee file that I'd like to have automatically compile into the script.js file loaded by index.html above by running something like coffee script.coffee -c -w.
Trouble is, I'm getting ReferenceErrors when I try to run the above command on the following script.coffee file:
jQuery ->
class ListView extends Backbone.View
el: $ 'body'
initialize: ->
_.bindAll @
@render()
render: ->
$(@el).append '<ul><li>Hello, Backbone!</li></ul>'
list_view = new ListView
For instance:
ReferenceError: jQuery is not defined
...
because, clearly, jQuery is being loaded in the index.html file.
Is there a way to suppress the error reporting from the coffeescript compiler so that it just converts the code without the error?

The options must go before the file, e.g.:
coffee -cw script.coffee
Otherwise, it will try to run script.coffee right then and there as a Node.js script, passing it the options -c and -w. That's not what you want; if you want the CoffeeScript compiler to get the options, it's got to be before the file name.
