Introduction

Smalltalk, a high-level, object-oriented programming language, has been a cornerstone of software development for decades. Its unique features, such as image-based persistence and dynamic typing, have made it a favorite among developers. However, the traditional Smalltalk environment has been limited to a few proprietary implementations. This is where Squeak comes in – a modern, open-source, full-featured implementation of the Smalltalk programming language and environment.

What is Squeak?

Squeak is a highly-portable, open-source implementation of the Smalltalk programming language and environment. Its virtual machine is written entirely in Smalltalk, making it easy to debug, analyze, and change. This unique architecture allows developers to modify the virtual machine itself, giving them unparalleled flexibility and control over the environment.

Key Features of Squeak

Open-source: Squeak is an open-source project, which means that developers can access the source code, modify it, and distribute it freely.
Highly-portable: Squeak's virtual machine is written in Smalltalk, making it easy to port to different platforms.
Full-featured: Squeak provides a comprehensive set of tools and libraries for developing a wide range of applications.
Image-based persistence: Squeak's image-based persistence allows developers to save the entire state of the system, including code, data, and runtime environment, making it easy to share and distribute applications.

History of Squeak

Squeak was first released in 1996 by the Squeak Team, a group of developers led by L. Peter Deutsch. The initial release was based on the Smalltalk-80 implementation, but it has since evolved into a unique and powerful platform in its own right. Over the years, Squeak has been used in a wide range of projects, from multimedia applications and educational platforms to commercial web application development.

Projects Built with Squeak

Squeak has been used in a variety of projects, including:

Etoys: A multimedia authoring system for children, which has been widely used in educational settings.
Croquet: A virtual world platform that allows users to create and interact with 3D environments.
Pharo: A modern, open-source implementation of the Smalltalk programming language and environment.
WebSqueak: A web-based implementation of the Squeak environment, which allows developers to create and deploy web applications using Smalltalk.

Why Choose Squeak?

So, why choose Squeak over other programming languages and environments? Here are a few reasons:

Unique architecture: Squeak's image-based persistence and dynamic typing make it a unique and powerful platform for developing a wide range of applications.
Open-source: Squeak is an open-source project, which means that developers can access the source code, modify it, and distribute it freely.
