Some of you may remember the guile-emacs project I started on years
ago. I let it slide a bit when other things got in the way, but the
last year or so I've been putting some work into it again.
I've got a source tree tracking the Emacs CVS sources which can be
configured to use Guile for the basic object representation, some of
the allocation, etc. It's got a simple Scheme evaluation mode, too,
which shouldn't be hard to enhance a bit. ("ism" looks remarkably
similar to "ielm"....) Lisp and Scheme can't really talk to each
other very well yet, though.
The Guile library is not unexec-friendly, so this version has to have
the unexec part of the Emacs build disabled. There are some glaring
but probably not difficult problems which I think may derive largely
from this (non-tty startup doesn't work; "make bootstrap" doesn't
work), but I'm working on them. In a terminal frame, the basics seem
to work -- I can run dired and shell mode, and font-lock mode colors
a C source file on a color xterm. I haven't stress-tested it, and
probably won't until I get X and/or Carbon display working, but at
the moment, while I know of a few things that don't work, and a lot
of Scheme-Lisp-interface type things people might eventually want
that aren't there yet, I'm currently not aware of any other serious
problems. Well, as long as you don't count the code quality in a few
places... :-)
If you'd like to play with it, see http://www.mit.edu/~raeburn/
guilemacs/ -- the current state is described there, and there's a
link to source to download. (No public repository at the moment,
sorry.) Let me know what you think, send patches, etc.
