Hi Guys,
I am using rails-3.1 which use CoffeeScript by default.
Does anybody know how to write jQuery plugin in CoffeeScript according to
official jQuery guide?
http://docs.jquery.com/Plugins/Authoring
I knew this:
https://gist.github.com/909017
but I think it''s different from jQuery official guide.
Also, can I remove ''function-call-this'' wrapper?
If I do that, will I bring myself into another trouble?
I mean: (function() { my code }).call(this);
Thanks :)
Kristianto

Not sure if it helps but I wrote this: https://gist.github.com/979717 a couple of months ago but I do not know if it adheres to the official guides.
