Running the slime function several times will create multiple connections as expected. Commands executed in Common Lisp buffers are applied to the current connection, which is by default the most recent one.
There are two ways to change the current implementation:
- Run M-x slime-next-connection.
- Run M-x slime-list-connections, which opens a buffer listing connections, and lets you choose the current one with the d key.
I find both impractical: the first one does not let me choose the implementation, forcing me to run potentially several times before getting the one I want. The second one opens a buffer but does not switch to it.
All I want is a prompt with completion. So I wrote one.
First we define a function to select a connection among existing one:
(defun g-slime-select-connection (prompt)
(interactive)
(let* ((connections-data
(mapcar (lambda (process)
(cons (slime-connection-name process) process))
slime-net-processes))
(completion-extra-properties
'(:annotation-function
(lambda (string)
(let* ((process (alist-get string minibuffer-completion-table
nil nil #'string=))
(contact (process-contact process)))
(if (consp contact)
(format " %s:%s" (car contact) (cadr contact))
(format " %S" contact))))))
(connection-name (completing-read prompt connections-data)))
(let ((connection (cl-find connection-name slime-net-processes
:key #'slime-connection-name
:test #'string=)))
(or connection
(error "Unknown SLIME connection %S" connection-name)))))Then use it to select a connection as the current one:
(defun g-slime-switch-connection ()
(interactive)
(let ((connection (g-slime-select-connection "Switch to connection: ")))
(slime-select-connection connection)
(message "Using connection %s" (slime-connection-name connection))))
I bind this function to C-c C-s c.
