A little module for converting CoffeeScript to a bookmarklet.

1. Compiles the CoffeeScript to Javascript using coffee-script.js
2. Minifies the code using Google's Closure Compiler (Simple mode)
3. Wraps the code for use as a bookmarklet, optionally with clever stuff by Ben Alman for loading jQuery.

The easiest way is to just use the tool here: http://johtso.github.com/CoffeeMarklet/

coffeemarklet(coffeescript, callback, [add_jquery, [jquery_version]])

coffeescript - String - The CoffeeScript to be converted.

callback - Function - The callback that will be passed the resulting bookmarklet.

add_jquery - Boolean - If true wraps the function in code adding jQuery to the page. Defaults to true.

jquery_version - String - The minimum jQuery version to be loaded.

Source CoffeeScript:

alert ('Hello' for i in [0..5]).join(', ')

Resulting bookmarklet without jQuery:

javascript:(function(){var a;alert(function(){var b;b=[];for(a=0;a<=5;a++)b.push("Hello");return b}().join(", "))}).call(this);

And with jQuery:

javascript:(function(e,a,g,h,f,c,b,d){if(!(f=e.jQuery)||g>f.fn.jquery||h(f)){c=a.createElement("script");c.type="text/javascript";c.src="http://ajax.googleapis.com/ajax/libs/jquery/"+g+"/jquery.min.js";c.onload=c.onreadystatechange=function(){if(!b&&(!(d=this.readyState)||d=="loaded"||d=="complete")){h((f=e.jQuery).noConflict(1),b=1);f(c).remove()}};a.documentElement.childNodes[0].appendChild(c)}})(window,document,"1.6.1",function($,L){alert("CoffeeScript and jQuery "+$.fn.jquery+"!");});
