Open Source Smalltalk Software

Pongo is a free MSN instant messenger client written in Smalltalk. It is cross platform, running on Windows, Mac, intel Linux and several other unix implementations.

The Pointrel System is an RDF-like triple store implemented on the Java/JVM platform, supporting related social semantic desktop applications to create, use, exchange, and organize informational resources for a reasonably joyful and secure world.

3SUM aims to provide a powerful 2 to 3D programmable environment that allow editing several kind of contents and linking the relationships among Objective-C type. 3SUM sits on the top of AP3 framework which consit of 3D screen graph Objective-C API, C++ geometry math classes, basic mesh implementations, raster compositor and thread managements. AP3 also have a few foundation classes for data manipulation purpose, such as AAObject root which allows tagging object with selector-keyed arbitrarily typed bytes, or AAChunk, an equal-entry array which allows managing two or more binary streams as a single multi-field stream, or striding one stream into some, and some other partitioning abstractions. AP3 also provides a GUI system for NSOperation management, to provide the concurrency as much as everywhere-possible.

Abora is a hypertext system supporting fine-grained links, transclusions and user link filtering. It is inspired by Ted Nelsons Xanadu and Udanax-Gold by XOC.

Brainbot is a general purpose robotics research platform, with an onboard PC. Brainbot's development was funded by the Brain Engineering Lab, the Neukom Institute, and HUV, Inc.

DoME (Domain Modeling Environment) is a project intended to provide a platform and language neutral modeling environment. This generalized framework provides a means to implement a generic modeling type. See http://www.htc.honeywell.com/dome

SCM (aka GemKit) provides source version control for GemStone/S. GS/S source code is stored in an ENVY repository. Changes made in the client development environment are automatically propagated to GS/S and optionally to the client execution environment.

Portable Smalltalk to JVM compiler. Has support different Smalltalk VM. Convenient and simple interaction with Java code.

Little Smalltalk was the first Smalltalk dialect developed outside of Xerox PARC (tm). We continue to develop it to provide a powerful, general purpose, full featured and portable dialect of the Smalltalk programming language.

Pocket Smalltalk is Smalltalk-80 for small machines. Currently we support PalmOS with a virtual machine. We are looking for ports to other devices. PSt consists of an IDE (currently for Win32), which generates executables from Smalltalk source.

A dialect-neutral Smalltalk library which supports communication with NMEA enabled devices, such as GPS receivers. The initial specific target device will be a Magellan GPS315 receiver.

A smalltalk interpreter focused for embedding in C++ projects.
