Writing a jquery plugin in coffeescript - how to get “(function($)” and “(jQuery)”?

Question

I am writing a jquery plugin in coffeescript but am not sure how to get the function wrapper part right.

My coffeescript starts with this:

$.fn.exten

UPDATE/EDIT: Yep, as per Jeremy's explanation:

$ = jQuery

$.fn.myPlugin = () ->
  console.log('test fired')

compiles to:

(function() {
  var $;
  $ = jQuery;
  $.fn.myPlugin = function() {
    return console.log('test fired');
  };
}).call(this);

Which works just fine as a jQuery plugin: $('body').myPlugin();

Okay, i think I may getting close on this one, let me know if it helps.

(($) ->
  $.fn.extend =
    myplugin: ->
    @each: ->
)(jQuery)

renders into:

(function() {
  (function($) {
    return $.fn.extend = {
      myplugin: function() {},
      this.each: function() {}
    };
  })(jQuery);
}).call(this);
