If you’d like to use emacs on one computer (i.e. your windows box at home) and use SLIME to connect to a Common Lisp process on a remote computer (i.e. your server at work), here’s how I do it.
First, create a startup file for your favorite Lisp implementation.
lisp startup file
(require 'asdf) (asdf:oos 'asdf:load-op 'swank) ; start swank (setf swank:*use-dedicated-output-stream* nil) (setf swank:*communication-style* :fd-handler) (swank:create-server :dont-close t)
Now edit your
~/.emacs so that you’ve got something like the following in it:
(require 'slime) (require 'tramp) (add-hook 'lisp-mode-hook (lambda () (slime-mode t))) (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t))) (setq lisp-indent-function 'common-lisp-indent-function slime-complete-symbol-function 'slime-fuzzy-complete-symbol) (slime-setup) ;;; If you want to tunnel through an intermediate host, such as your ;;; work firewall, use the following couple lines. If you're using a ;;; Windows emacs, use 'plink' as below, otherwise substitute 'ssh'. (add-to-list 'tramp-default-proxies-alist '("\\.work-domain\\.com" nil "/plink:email@example.com:/")) (add-to-list 'tramp-default-proxies-alist '("firewall\\.work-domain\\.com" nil nil)) (defvar *my-box-tramp-path* "/ssh:firstname.lastname@example.org:") (defvar *current-tramp-path* nil) (defun connect-to-host (path) (setq *current-tramp-path* path) (setq slime-translate-from-lisp-filename-function (lambda (f) (concat *current-tramp-path* f))) (setq slime-translate-to-lisp-filename-function (lambda (f) (substring f (length *current-tramp-path*)))) (slime-connect "localhost" 4005)) (defun my-box-slime () (interactive) (connect-to-host *my-box-tramp-path*)) (defun my-box-homedir () (interactive) (find-file (concat *server-tramp-path* "/home/me/")))
Now, load up the startup file you created on your host Lisp to start
the swank server. Then, create an ssh tunnel, i.e.
Now you can
M-x my-box-slime to connect through your SSH
tunnel to your work box; SLIME’s
M-. command will also
correctly open up the file containing the defun of whatever’s under
your cursor, and
C-c C-k works correctly, etc. If you want
to open up some lisp file,
M-x my-box-homedir is a convenient
For Windows users
If you’re using Windows and want to also use a multi-hop tramp method (i.e. ssh into your work firewall, and then ssh from there to your server at work), be aware that tramp 2.1.4 and prior has a bug; it’s fixed in CVS and probably 2.1.5, which is not out yet. Information and a patch is available here.
You’ll also want to use
plink from the PuTTY distribution in lieu of
ssh. If you’re doing multi-hop tramp, though, you need to use plink for the
first hop (Windows box -> “firewall” box) and ssh thereafter (“firewall” ->
