My intent is pretty close of what you say. I just want to provide a
simple repl directly inside the OpenGL window. I see mostly four
reasons to do this.
- csi + readline + thread is problematic (from my test, maybe I'm wrong).
  Although I say 'simple' some file saving/reading would be great.
  csi without readline is very poor to make real editing session.
- I've to switch from vim to emacs + quack + paredit. In a sense, I'm
  to OpenGL programming with Chicken, that's enough for me for the moment.
  Having the repl in OpenGL is a practical, reusable block of code.
  It can serve in a real program, see autocad, or maya (mel language),
and so on.
- Once it's done, people have ideas to experiment with. That's what make you
  lost track :)
- I've forgot the fourth point, something like "it's fun" :)

Oh, this is my intent regarding the opengl repl. I also want to
provide other simple building blocks. Font system is one.
Camera/projections library is another one.

Editor stuff was just discussions, I'm not going to do it but I
believe once some building blocks are done, people will try to do

I don't know Squeak. I've heard about Morphs (for Smalltalk I think)
but that's all. I need to look at it.

Hi folks,

This is a 'private' announce :)
Thanks to Felix, gl-display-glx and gl-font are in svn/chicken-eggs on galinha.
Also, I've added the "project" to the active projects page on the wiki.
I should have waited a bit, but Shawn (and others) showed interest, so...
