GNU Smalltalk Sprint


Hi All,

The GNU Smalltalk sprint will be done during this week end (11-12 December)
It will be done on IRC #gnu-smalltalk on Freenode (
and it is open to everybody :)

Some proposed tasks:
- VisualGST
- Coverage tool (for method-coverage, it can be based on gst-profile)
- SUnit testcases for CObject and everything not currently covered
- Fixing the compiler (
- Fixing gst-remote ( and
- Fixing GTK on OSX
- Packages (atomic loading, package builder, ...)
- Allow VisualGST to hook up to a headless gst like gst-remote does.
Just imagine how much fun working on a running Iliad app you could
have with this.

GNU Lightning binding

Hi everybody,

Mathieu and I are proud to announce the first release
of the GNU Lightning binding for GNU Smalltalk. GNU
lightning exposes a portable interface for generating
machine language at run-time. GNU lightning is fast and
tries to be as little intrusive as possible, so that the
generated code can also be optimized easily. So far,
it has been ported to the x86, SPARC and PowerPC

You can find the source code here:

To install it:

git clone git://
autoreconf -vi
