Some more background https://larrymasinter.net/stefik-loops.pdf and https://www.markstefik.com/?page_id=334 I think LOOPS was limited by only being available on Interlisp-D related systems. Common LOOPS was

The answer is mostly about CLOS and not about LOOPS. Update: my remark was about an earlier posted content, which had an "AI" generated answer. That text has been removed.

LOOPS was one of the early frameworks for AI programming (-> for Knowledge-based Systems -> especially Expert Systems) in Lisp, which also made use of the new graphical user interface of the Interlisp-D Lisp Machine from Xerox. Interl

LOOP has the DO functionality included. Example: CL-USER 18 > (do ((a 1 (+ a 1)) (b 10 (* b 1.5)) (c nil)) ((> a 5) (list a b (reverse c))) (p

Why wouldn't one be able to implement this in JavaScript, Python, Smalltalk or even BASIC ?

Especially since many compiler-only implementations can evaluate Lisp code at runtime, just fine, even though they don't execute s-expressions in an Interpreter. Thus an compiler-only Lisp can be used to implement Emacs just fine. I us

There are two open source emulators of actual Lisp Machines I would recommend: Interlisp-D/Medley: https://interlisp.org MIT CADR: https://tumbleweed.nu/lm-3/ These run an actual Lisp operating system.

Right, Open Genera uses ONLY an X11 console, and thus requires TCP/IP. But that was the case on other machines, too. The embedded UX400/1200 machines and the headless NXP1000 use an X11 console, too. Lots of TV software does not r

If you say only Lisp can be used to implement Emacs, would you mean a specific Emacs or an editor belonging to the larger family of Emacs-like editors? When I would speak about how to implement "an Emacs", I would include the opti

GNU Emacs is a Lisp implementation with an abstraction layer over the hardware and OS. I would like to reserve "Lisp Machine" to computers with an actual Lisp operating system or emulations of those.

Good luck with that. I don't think that's possible.

Racket now gets a new, non-s-expression, syntax. The Lisp syntax is said to be a problem hindering wider adoption.
