The components required are:
# pacman -S emacs sbcl slime-cvs
Note: It is also possible to install slime from the AUR, though the -cvs package is recommended by the upstream developers.
From the .INSTALL file.
To make use of slime, add the following lines to your init file:
(setq inferior-lisp-program "/path/to/lisp-executable") (add-to-list 'load-path "/usr/share/emacs/site-lisp/slime/") (require 'slime) (slime-setup)
Then run M-x slime from within emacs.
