Installing Slime

 Slime is an emacs mode for interacting with Common Lisp systems.

The SLIME developers recommend that users  download the CVS version. It changes often and usually for the better. The emacs and lisp sides (the lisp side is known as Swank) need to be in kept in sync, since the protocol they utilize is volatile.

Configuration

If you don't already have one, create a file called .emacs in your home directory. On Windows systems, it's not always clear what emacs thinks your home directory is. You can type C-x C-f and use "~/.emacs" as the file to find and you'll end up in the right place. (That works on Unix systems, too, of course.)

Add the following code fragments to your .emacs file to configure Slime to work with Clozure CL, using UTF-8 as the default encoding.

(set-language-environment "utf-8")

(add-to-list 'load-path "~/src/slime/")  ;or wherever you put it

;;; Note that if you save a heap image, the character
;;; encoding specified on the command line will be preserved,
;;; and you won't have to specify the -K utf-8 any more.
(setq inferior-lisp-program "/usr/local/bin/ccl64 -K utf-8")

(require 'slime)
(setq slime-net-coding-system 'utf-8-unix)
(slime-setup '(slime-fancy))

With this in place, you should be able to start up SLIME with M-x slime, and print and read Unicode characters:

CCL> (format t "~c" #\u+2021)
‡                                                                               
NIL
