Name:
OPS
Package Name:
OPS
Description:
Interpreter for Ops5, a programming language for production systems.
Author:
Charles L. Forgy. Ported to Common lisp by George Wood and Jim Kowalski.
CMU Common Lisp mods by Dario Guise, Skef Wholey, and Dan Kuokka.
Maintainer:
Not really maintained.
Copyright Status:
Public domain.
Files:
ops.lisp, ops-backup.lisp, ops-compile.lisp, ops-io.lisp, ops-main.lisp,
ops-match.lisp, ops-rhs.lisp, ops-util.lisp, ops.catalog, *.ops
Portability:
Should run in any legal Common Lisp implementation.
Instructions:
To compile for CMU Common Lisp, (load "library:contrib/ops/compile-ops").
After OPS has been compiled, you can (load "library:contrib/ops/ops.fasl").
Then go into the OPS package with (in-package :ops). Now you can load your
OPS5 code or start typing in productions.
There are a number of demos and sample programs; particularly amusing is the
Haunt adventure game. Do (load "<name>.ops"), then "(run)". Many systems
require an initial "(make start)" before the "(run)" --- if this is missing,
"(run)" will do nothing. Set *ptrace* to NIL to eliminate production tracing.
See the OPS5 User's Manual, July 1981, by Forgy, CMU CSD.
Bugs:
This has been put in its own package, but only a few interfaces have been
exported. You must run in the ops package.
