Download
Objective-S source code is available on github:
https://github.com/mpw/Objective-Smalltalk.
It requires MPWFoundation, which actually implements much of the architectural components and connectors:
https://github.com/mpw/MPWFoundation.
Build
The two frameworks are best built together in a workspace. You can use the one included in Objective-S or use your own. Building either the Objective-Smalltalk target or one of the sample applications should build everything.
Sample Applications
Objective-S includes a number of sample applications
stsh
A Unix command line interpreter that can be used interactively or for script execution. In addition to the MPWFoundation and Objective-Smalltalk frameworks, this also requires Stsh.framework, which is part of the Objective-Smalltalk project and built automatically.
In order to use, the frameworks must be copied to /Library/Frameworks/ and stsh
itself to /usr/local/bin/.
Smalltalk.app
A very early cut at duplicating small parts of the Smalltalk integrated image experience without
actually having an image. Right now, you can open multiple workspaces and a REPL.
Apart from general exploration and programming tasks, I've also been using the Smalltalk.app
together with the Slides3D framework to create presentations.
Sample Scripts
The scripts
directory in the Objective-Smalltalk project includes a number of example scripts.
