So OK, lisp hacking is very addictive, I gave it a try:
This code kind of works: I could not figure out how to bind
*terminal-io* thus no print functions work, break loops and toplevel
commands are also absent, but hey you can evaluate lisp code. Anyway,
it would be much nicer to use the real openmcl toplevel-loop. I had a
look, but I think there must be people who can do this much quicker -
it would take me too long to even understand the code....
What we need is the equivalent of the acl code:
(defun start-telnet-session (s from)
(let ((*in-telnet-session* t))
s 'tpl:top-level-read-eval-print-loop nil)))
(ignore-errors (close s)))
(format t "telnet server: closing connection from ~a~%" from))
In particular starting another toplevel loop (I hope that having
multiple toplevel loops is different processes possible, otherwise the
server could be made single threaded).
