FunTang : functional features added CoffeeScript

Make CoffeeScript sweeter !

FunTang is a little language that compiles into CoffeeScript. It adds some functional features into CoffeeScript :

• Immutable Variables : by converting variables to functions, which receive nothing and return the value of the variable.
• Lazy Evaluation : by converting applications to cached functions.

CoffeeScript had made a apt-to-use Curried feature by it's syntax of function :

• Curried Function ( original CoffeeScript ) : fn = (x)->(y)-> x * y

This project will focus on Immutable Variables and Lazy Evalution features at begining, and add other features like Guard ( to replace if...else) ,or even Pattern Matching later.

CAVEAT : FunTang compiler can't compile original CoffeeScripts, but it can generate normal CoffeeScripts, which can be compiled with other .coffee files. So if you want to use other CoffeeScript libraries with FunTang codes, the only way is 'link' them after compiling. This problem may be fixed by adding some foreign language features in the near future.

Full Featured Example

This example show all features in the FunTang language.

()->x y
()->x y
(x)->(y)->x y
()->x y x x y y y
gsf = (a,b,c,d,e)->()->x "yacc" 34.12313
                      'led'  3
                      'leet'
ff = ()->(x,y)->(z,w)->x 
                       y 
                       w

The compiler can compile above codes into normal CoffeeScript.

About the name

'Fang Tang' is a Chinese word means the 'sugar cube' in English. And the misspell 'Fun' is for 'functional' , which sounds similar to 'Fang'. So it becomes a perfect name for this CoffeeScript extension project.
