This contrib implements a Lisp Listener along with some niceties like

This used to be the default REPL for SLIME, but it was hard to

;;;; REPL
;;
;; The REPL uses some markers to separate input from output. The
;; usual configuration is as follows:
;;
;; ... output ... ... result ... prompt> ... input ...
;; ^ ^ ^ ^ ^
;; output-start output-end prompt-start input-start point-max
;;
;; input-start is a right inserting marker, because
;; we want it to stay behind when the user inserts text.
;;
;; We maintain the following invariant:
;;
;; output-start <= output-end <= input-start.
;;
;; This invariant is important, because we must be prepared for
;; asynchronous output and asynchronous reads. ("Asynchronous" means,
;; triggered by Lisp and not by Emacs.)
;;
;; All output is inserted at the output-end marker. Some care must be
;; taken when output-end and input-start are at the same position: if
;; we insert at that point, we must move the right markers. We should
;; also not leave (window-)point in the middle of the new output. The
;; idiom we use is a combination to slime-save-marker,
;; insert-before-markers, and manually updating window-point
;; afterwards.
;;
;; A "synchronous" evaluation request proceeds as follows: the user
;; inserts some text between input-start and point-max and then hits
;; return. We send that region to Lisp, move the output and input
;; makers to the line after the input and wait. When we receive the
;; result, we insert it together with a prompt between the output-end
;; and input-start mark. See `slime-repl-insert-prompt'.
;;
;; It is possible that some output for such an evaluation request
;; arrives after the result. This output is inserted before the
;; result (and before the prompt).
;;
;; If we are in "reading" state, e.g., during a call to Y-OR-N-P,
;; there is no prompt between output-end and input-start.
