Smalltalk 80

Focuses on Implementation of System; Provides Documentation & Covers General Software & Engineering

This book provides an introduction to the understanding and use of object-oriented methodologies for engineering problem solving with a specific emphasis on analysis and design. (Object-oriented programming is a general computer language methodology. The name comes from the focus on describing problems in terms of objects, both physical and conceptual).

This book focuses on object-oriented concurrent computing, which can be considered a model of concurrent programming, and proposes a new programming language, ConcurrentSmalltalk, which is based on object-oriented concurrent computing. The book also shows the efficiency of object-oriented concurrent computing through the design, implementation, and evaluation of ConcurrentSmalltalk. ConcurrentSmalltalk is designed to be upwardly compatible with Smalltalk-80. In the book, the ConcurrentSmalltalk object model is first proposed. Next, issues which arise from maintaining compatibility with Smalltalk-80 are discussed. Finally, the ConcurrentSmalltalk virtual machine which executes the ConcurrentSmalltalk programs is proposed.

Budd's introduction to Smalltalk programming and the Little Smalltalk interpreter focuses on elementary, rather than advanced topics of object-oriented programming. The Little Smalltalk system runs under the UNIX operating system and can be executed on conventional terminals.

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 entirely 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. -- Preface.
