Hi,
I want to announce two projects for GNU Smalltalk:
1) Multiple domains or "kernels" support in the VM:
---------------------------------------------------
The problem with Smalltalk is it doesn't know what is a "program",
if you start two programs and the first change the class A it will
impact the second programs that use it; this is a simple example,
there are also the memory iterations, or security issues with
reflection, ...
Now with the domain models you are allowed to create multiple
environments that are separate/isolated from each others. I plan to
improve the IDE to support it. I will write others posts to explain in
depth the implementation and how to use it.
[email protected]:MrGwen/GNU-Smalltalk.git the branch domain
2) GST Without ObjectTables:
----------------------------
I've started it for fun :D, don't expect a fully running GST, now
I've made a tool that generate a small image (1,5 Mo don't forget 64
bits pointers) and just send few messages and after it crashes ;-)
I've removed the c bootstrap code, the compiler, and break a lot of
stuffs too (like the GC :D) . My plans are to make the VM model simple.
GST knows too much stuffs when I've implemented the domain support I was
afraid by the number of classes, symbols known by the VM.
For the GC I don't know what I'll do, I think we could disuss on the
ml about a nice GC model (don't stop the world and // compaction).
Anyway that's the beginning of a new story.
But the first step is to clean up what I've done.

Cheers,
Gwen
