Overview

SLIME is the Superior Lisp Interaction Mode for Emacs. It is implemented in two main parts: the Emacs Lisp side (slime.el), and the support library for the Common Lisp (swank.lisp and swank-*.lisp)

For a real description, see the manual in doc/ or browse an online version here.

Quick setup instructions

Add this to your ~/.emacs file and fill in the appropriate filenames:

;; setup load-path and autoloads
(add-to-list 'load-path "~/dir/to/cloned/slime")
(require 'slime-autoloads)

;; Set your lisp system and, optionally, some contribs
(setq inferior-lisp-program "/opt/sbcl/bin/sbcl")
(setq slime-contribs '(slime-fancy))

Use M-x slime to fire up and connect to an inferior Lisp. SLIME will now automatically be available in your Lisp source buffers.

Contribs

SLIME comes with additional contributed packages or "contribs". When SLIME is loaded it loads the contribs you set up before in slime-contribs. You can use the command slime-setup to reload contribs.

The most-often used contrib is slime-fancy, which primarily installs a popular set of other contributed packages. It includes a better REPL, and many more nice features.

Licence

SLIME is free software. All files, unless explicitly stated otherwise, are public domain.
