This directory contains application packages for CLISP.

The .orig files contain the original distribution from beta.xerom.com.
The .clisp files contain the sources, modified to run on CLISP.
I am not distributing memory images of these. You can compile it yourself,
just by typing "make" in the corresponding directory.


PCL is an implementation of a large subset of CLOS.
From the CLISP version 1993-09-01 on, CLISP has a native CLOS. You do not
need PCL any more (except if you want to program at the meta-object protocol
level).


CLX is an interface to the X window system. (Unix version of CLISP only.)


Garnet is a Lisp-based graphical user interface.


GDI is a low-level win32 graphics library to make Garnet work on win32.


MCS is an object system for Common Lisp which emphasizes the use of
metaclasses.


SERIES is Richard C. Waters' Series package, as described in the appendix
of CLtL2. series-diffs contains the diffs from the original distribution to
this distribution.


Screamer is an extension for nondeterministic programming.


XP is a Common Lisp ``pretty'' printer.


XP-Prolog is my own small experimental prolog-like interpreter.

From the comp.lang.lisp FAQ:

PCL -- parcftp.xerox.com:pcl/ [13.1.64.94]
Portable Common Loops (PCL) is a portable implementation of
the Common Lisp Object System (CLOS). A miniature CLOS
implementation called Closette is available pcl/mop/closette.lisp.

MCS (Meta Class System) -- ftp.gmd.de:/lang/lisp/mcs/ [129.26.8.90]
Portable object-oriented extension to Common Lisp. Integrates the
functionality of CLOS (the Common Lisp Object System), and TELOS, (the
object system of LeLisp Version 16 and EuLisp). MCS provides a metaobject
protocol which the user can specialize. Runs in any valid Common Lisp.

CLUE (Common Lisp User-Interface Environment) is from TI, and extends CLX
to provide a simple, object-oriented toolkit (like Xt) library that uses
CLOS. Provides basic window classes, some stream I/O facilities, and a few
other utilities. Still pretty low level (it's a toolkit, not widget
library). Available free by anonymous ftp from csc.ti.com:pub/clue.tar.Z
Written by Kerry Kimbrough. Send bug reports to clue-bugs@dsg.csc.ti.com.

CLIO (Common Lisp Interactive Objects) is a GUI from the people who created
CLUE. It provides a set of CLOS classes that represent the standard
components of an object-oriented user interface -- such as text, menus,
buttons, scroller, and dialogs. It is included as part of the CLUE
distribution, along with some packages that use it, both sample and real.

XIT (X User Interface Toolkit) is an object-oriented user interface
toolkit for the X Window System based on Common Lisp, CLOS, CLX, and
CLUE. It has been developed by the Research Group DRUID at the
Department of Computer Science of the University of Stuttgart as a
framework for Common Lisp/CLOS applications with graphical user
interfaces for the X Window System. The work is based on the USIT
system developed by the Research Group INFORM at the University of
Stuttgart. Although the system kernel is quite stable, XIT is still
under active development. XIT can be obtained free by anonymous ftp
from ifi.informatik.uni-stuttgart.de (129.69.211.1) in the directory
/pub/xit/.

Garnet is a large and flexible GUI. Lots of high-level features. Does
*not* depend on CLOS, but does depend on CLX. Garnet (version 2.0 and
after) is now in the public domain, and has no licensing restrictions,
so it is available to all foreign sites and for commercial uses.
Detailed instructions for obtaining it by anonymous ftp are available
by anonymous ftp from a.gp.cs.cmu.edu [128.2.242.7] as the file
/usr/garnet/garnet/README. Garnet includes the Lapidiary interactive
design tool, C32 constraint editor, spreadsheet object, Gilt
Interface Builder, automatic display management, two
widget sets (Motif look-and-feel and Garnet look-and-feel), support for
gesture recognition, and automatic constraint maintenance, application
data layout and PostScript generation. Runs in virtually any Common
Lisp environment, including Allegro, Lucid, CMU, and Harlequin Common
Lisps on Sun, DEC, HP, Apollo, IBM 6000, and many other machines.
Garnet helps implement highly-interactive, graphical, direct
manipulation programs for X/11 in Common Lisp. Typical applications
include: drawing programs similar to Macintosh MacDraw, user interfaces
for expert systems and other AI applications, box and arrow diagram
editors, graphical programming languages, game user interfaces,
simulation and process monitoring programs, user interface construction
tools, CAD/CAM programs, etc. Contact Brad Myers (bam@a.gp.cs.cmu.edu)
for more information. Bug reports and administrative questions:
garnet@cs.cmu.edu. Garnet is discussed on the newsgroup comp.windows.garnet.

Screamer is an extension of Common Lisp that adds support for
nondeterministic programming. Screamer consists of two levels. The
basic nondeterministic level adds support for backtracking and
undoable side effects. On top of this nondeterministic substrate,
Screamer provides a comprehensive constraint programming language in
which one can formulate and solve mixed systems of numeric and
symbolic constraints. Together, these two levels augment Common Lisp
with practically all of the functionality of both Prolog and
constraint logic programming languages such as CHiP and CLP(R).
Furthermore, Screamer is fully integrated with Common Lisp.
Screamer is available by anonymous FTP from ftp.ai.mit.edu as the file
/pub/screamer.tar.Z. Contact Jeffrey Mark Siskind <qobi@ai.mit.edu> for
further information.
