Nu is an interpreted object-oriented programming language, with a Lisp-like syntax, created by Tim Burks as an alternative scripting language to program OS X through its Cocoa application programming interface (API).
The language was first announced at C4,[1] a conference for indie Mac developers held in August 2007.
This Nu code defines a simple complex numbers class.
The example is a basic definition of a complex number: it defines the instance variables, and a method to initialize the object.
This sample, from the nuke tool bundled with Nu, also shows the influence of Objective-C, Lisp, and Ruby in the design of the language.
