Squeak By Example

Squeak is a modern, open source, fully-featured implementation of the
Smalltalk programming language and environment.
Squeak is highly portable — even its virtual machine is written en-
tirely in Smalltalk, making it easy to debug, analyze, and change. Squeak
is the vehicle for a wide range of innovative projects from multimedia
applications and educational platforms to commercial web development
environments

This book presents the various aspects of Squeak, starting with the basics,
and proceeding to more advanced topics.
This book will not teach you how to program. The reader should have
some familiarity with programming languages. Some background with
object-oriented programming would be helpful.
This book will introduce the Squeak programming environment, the
language and the associated tools. You will be exposed to common idioms
and practices, but the focus is on the technology, not on object-oriented
design. Wherever possible, we will show you lots of examples. (We have
been inspired by Alec Sharp’s excellent book on Smalltalk.
