[comp.windows.ms] Xlisp windowing system....

jonnyg@umd5.umd.edu (Jon Greenblatt) (02/10/89)

	Hello windows hackers.  Recently I have been writing windowing
version of xlisp version 2.0.  Xlisp is an public domain object oriented
lisp written for PC's and unix systems.  Right now the port is fairly
extensive and runs under X Windows and MS Windows.  The X Windows version is
very stable but the MS Windows version seems to run in to random blotches.
Given the problems of MS Windows I am foregoing that and am now working on a
Presentation Manager version -- (NO FLAMES!!!).

	Supported so far is a small but complete library of lisp callable
routines to create, manage, and draw on windows in a manner independent
of the current windowing system. I have a extensive class library
to handles scroll bars, text, and complex objects. Code written on one
windowing system is completely transportable to another. The object library
is written in such a way that it is easy to use. It is ideal for class
projects.

	The code is still in it's infancy. I am looking for a few good
programmers who are interested in pre Alpha copies of my code. If you
wish to be a pre Alpha site I will expect some form of input that will
help me in my porting. Those who wish to use the MS Windows port
will have to help me fix the current problems which may be related to
some tricky compiler bugs or strange windows memory interactions.

	The code is set up in such a way to make a port to the Mac fairly
easy if someone wants to put their hand into that.  I am limiting this to at
most 5 people.  Xlisp was written by David Betz and the copyright belongs to
him.  People who help me will have their names added to the windows code
source.

	Please do not ask me for a copy of xlisp2.0, if you cannot get it
from the uunet archives I cannot help you, sorry. I expect only replies
from interested Alpha sites. Please include in your response reasons why
I shoud consider you as an pre Alpha site (ie: I could really use something
like this or I would like to port it to ....), also include you programming
experience in C and windowing environments. All code will become public
domain when completed.
