javascript - 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.extend({
    myplugin: ->
        @each ->

Which creates the javascript with a function wrapper:

(function() {
  $.fn.extend({
      myplugin: function() {
          return this.each(function() {

but I want a '$' passed in like this:

(function($) {
  $.fn.extend({

Similar for the ending I have... nothing in particular in coffeescript.
I get this in javascript:

})();

But would like this:

})(jQuery);

Does anyone know how to achieve this with the coffeescript compiler? Or what is the best way to get this done within coffeescript?

The answer is that you don't need to call it like that in CoffeeScript -- your script is already safely wrapped in a closure, so there's no need for jQuery-passed-in-as-a-parameter-tricks. Just write:

$ = jQuery

... at the top of your script, and you're good to go.
