22 The Strongtalk System: A Fast, Strongly-Typed Smalltalk
Sun Microsystems, Inc.Steffen Grarup
The Strongtalk system is a fundamental rethinking of Smalltalk-80. While maintaining the basic syntax and semantics of
the Smalltalk-80 language, it contains significant advances in a variety of areas relative to previous Smalltalk implementations,
- a virtual machine that executes Smalltalk considerably faster than any other implementation
- the first complete strong, static type system for Smalltalk (use of which is completely optional and incremental, and which
does not affect performance), as well as a typed Blue Book library
- a flyweight, glyph-based user interface that nonetheless allows integration of native widgets, and which provides automatic
layout using Tex-style shrink/stretch semantics
- use of mixins to provide a simple, elegant alternative to multiple inheritance.
Sun Microsystems, Inc. has recently released the Strongtalk system as free, unsupported software under a partially open-source
license for the benefit of researchers and Smalltalk implementers. This demonstration will give them an opportunity to talk
with a founder of the Strongtalk project, and see the system in action.
