Squeak Smalltalk programming language

Introduction to Squeak Smalltalk programming language:

The Squeak Smalltalk programming language is a dialect of Smalltalk and is object-oriented, reflective and className-based. It was derived directly from Smalltalk-80. Squeak Smalltalk is a open source and full-featured implementation of the powerful Smalltalk programming language and environment. Squeak is highly-portable - even its virtual machine is written entirely in Smalltalk which makes easy to debug, analyze, and change. It is the vehicle for a wide range of projects from multimedia applications and educational platforms to commercial web application development. The Squeak system includes code for generating a new version of the virtual machine (VM) on which it runs. It includes a VM simulator written in Squeak itself.

Feature of the Squeak Smalltalk programming language:

  • Squeak's virtual machine is developed using Squeak itself.
  • Squeak are used for Web Application Development.
  • Croquet project and Balloon are the examples of Interactive 3D in Squeak!
  • It has superb multi-media potential.
  • Squeak is internationalised.
  • Squeak is a persistent environment - when you save your image, everything right down to the position of windows and text is saved.
  • Squeak itself is an IDE.
  • Squeak uses incremental compiling.

Programming Code:

  Fibonacci numbers:
fibonacci: n | numbers a b | numbers := OrderedCollection new. a := 1. b := 1. [ numbers size < n ] whileTrue: [ | temp | numbers add: a. temp := b. b := a + b. a := temp. ]. ^ numbers. `}
