| The attached patch make SLIME-CONNECTION ask "No connection: start | Slime?" if there is no connection -- and then wait for the connection | to come up.

FWIW. I have been patching slime-connection from the very beginning to get this behaviour.

The added code [above] would make sense in the next cond branch too. However I typically wish to connect to a lisp running swank at port 4005, started OUTSIDE of emacs --- Here is my local definition, to illustrate the idea

(defun slime-connection () ;;madhu 050404 "Return the connection to use for Lisp interaction. Signal an error if there's no connection." (let ((conn (slime-current-connection))) (unless conn (when slime-net-processes (setq slime-default-connection (car slime-net-processes)) (setq conn (slime-current-connection)))) (cond ((and (not conn) slime-net-processes) (error "No default connection selected. XXX")) ; after trying ((not conn) (or (and (y-or-n-p "Not connected. connect now? ") (slime-connect "localhost" 4005)) (error "Not connected."))) ((not (eq (process-status conn) 'open)) (or (and (y-or-n-p "Connection closed. connect now? ") (slime-connect "localhost" 4005)) (error "Connection closed."))) (t conn))))

This [rearrangement of windows] is indeed annoying
