【Coffee】Nodejs and CoffeeScript installation in windows

　　　　The CoffeeScript compiler is itself written in CoffeeScript, using the Jison parser generator. The command-line version of coffee is available as a Node.js utility. 

 

1. Install Nodejs

　　　　The most easy way is to download the msi filre fromhttp://nodejs.org/ . If you don't know how to install msi file ,you can read my another blog http://www.cnblogs.com/younglaker/archive/2013/05/29/3106377.html

　　　　Of cause there are another compelecated way to copmile the source code. But i don't like to . The simplest, the best.

　　　　You can use "node -v" and "npm -v" to check whether it is installed correctlty (npm is the the Node Package Manager).

 

2. Install CoffeeScript with npm

 

npm install -g coffee-script

　　　　(Leave off the -g if you don't wish to install globally.)

　　or 

　　　　If you'd prefer to install the latest master version of CoffeeScript, you can clone the CoffeeScript source repository from GitHub, or download the source directly. To install the lastest master CoffeeScript compiler with npm:

npm install -g http://github.com/jashkenas/coffee-script/tarball/master

　　

　　　　Cheked by "coffee -v".

 

3. Add environment path.

NODE_PATH : C:\Users\username\AppData\Roaming\npm\node_modules
 

 

　　

4. Test

　　　　Open cmd,paste 

 

square = (x) -> x * x
cube   = (x) -> square(x) * x　

 

 

　　　　It will output this:

 

square = function(x) {
  return x * x;
};

cube = function(x) {
  return square(x) * x;
};

 

　　　　That's fine.
