Nu is an interpreted object-oriented programming language, with a LISP-like syntax, created by Tim Burks as an alternative scripting language to program Mac OS X through its Cocoa API.

There is also a language implementation for Linux, and the iPhone.

The language was first announced at C4[1], the conference for indie Mac developers hold on August 2007.

Example code

This Nu code defines a simple complex numbers class.

(class Complex is NSObject
  (ivar (double) real
        (double) imaginary)
 
  (- initWithReal:(double) x imaginary:(double) y is
    (super init)
    (set @real x)
    (set @imaginary y)
    self))

The example is a basic definition of a complex number (it just defines the instance variables, and a method to initialize the object). It evidences the similarity between the Nu code and the equivalent Objective-C code; it evidences also the similarity with Ruby.
