Nu (programming language)

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 defines the instance variables, and a method to initialize the object. It shows the similarity between the code in Nu and the equivalent in Objective-C; it also shows the similarity with Ruby.

(unless @prefix
        (set @prefix 
             "#{((((NSProcessInfo processInfo) arguments) 0) dirName)}.."))

(unless @icon_files 
        (set @icon_files 
             (array "#{@prefix}/share/nu/resources/nu.icns")))

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.
