js2coffee.org helps your learn coffeescript faster

Coffee-script is a smoking hot simple language that converts 100% into Javascript code. Coffee-script allows you to spend more time focusing on the algorithm rather than the syntax.
js2coffee.org is an awesome website that converts your Coffee-script to Javascript and vice versa on the fly. So you can learn Coffee-script faster.
Example:
Let’s convert my Random Number Generator code from a previous post to Coffee-script.

// Javascript version
var getRandomNum = function( i, decLen ){
	return (Math.random() * (i||1) ).toFixed(decLen);
};

# My Coffee-script version
getRandomNum = ( i=1, decLen ) -> (Math.random()*i).toFixed(decLen)

# js2coffee.org Coffee-script verison
getRandomNum = (i, decLen) ->
	(Math.random() * (i or 1)).toFixed decLen

Awesome huh?

Check out a demo of Coffeescript here.

I’ll like to leave you with a HTML5 Coffee-script presentation.

Cheers.

How to install Docco.coffee on Windows 7

Docco.coffee requires the following to run.

  1. Node.js
  2. Python
  3. CoffeeScript
  4. Pygments
  5. Docco

Step 1:
Download and install Node.js and Python 2.7. Python 3.2 might work but I haven’t yet tried it out.

Step 2:
Add the root and ‘node_modules’ directories for node.js and the root and “Script” directory for python 2.7 to your path environment variable.
C:\nodejs;%userprofile%\node_modules\.bin;C:\python27;C:\Python27\Scripts;

Step 3:
Open up a command prompt, start -> run -> type “cmd”.

Type npm install coffee-script
*You should see installation output on the screen*

Type npm install docco
*You should see installation output on the screen*

Step 4:
Download ez_setup
In command prompt, navigate to where you downloaded ez_setup.py.
Type in python ez_setup.py.

Step 5:
In command prompt type easy_install pygments to install Pygments.

Done.

Test
Download ‘underscore.js’ to your desktop.

Open up a command prompt and type in docco %userprofile%\desktop\underscore.js.
You should see two output files, “p” and “docs”.
The annotated source code is the html file in the docs folder.

Enjoy!
