It's Smalltalk!

It's Smalltalk!

Everything is an object. Objects collaborate by exchanging messages to achieve the desired application behavior. The Smalltalk programming language has a concise syntax and simple execution semantics. The Smalltalk system is implemented in itself: Compiler, debugger, programming tools, and so on are all Smalltalk code the user can read and modify. Novice programmers can get started easily and experts can engineer elegant solutions at large.

Morphic UI Framework

Morphic UI Framework

All graphical objects are tangible and interactively changeable. This promotes short feedback loops and low-effort application development. Morphic thus leverages the live programming experience of traditional Smalltalk environments from a mainly text-focused domain to a graphical one.

Powerful Tooling

Powerful Tooling

The dynamic Squeak environment provides a variety of tools for browsing, writing, executing, and versioning Smalltalk code. Multiple debugging sessions can be served concurrently. Thanks to Morphic, tool customization can be achieved with reasonable effort.

Fast Virtual Machine

There are several fast Squeak VMs that also support other languages of the Smalltalk family. Meta-tracing, just-in-time compilation, stack-to-register mapping, and aggressive in-line message caching yield efficiency in executing Smalltalk byte code.

Web Development

Web Development

With frameworks like Seaside and AIDA, Squeak can be a web server. It provides a layered set of abstractions over HTTP and HTML that let you build highly interactive web applications quickly, reusably,` and maintainably.

Multi-Platform Support

Multi-Platform Support

Squeak supports Windows, Linux, and OS X and is preinstalled on C.H.I.P., Raspberry Pi, and OLPC XO.
