Overview

SLIME is the Superior Lisp Interaction Mode for Emacs.

SLIME extends Emacs with support for interactive programming in Common Lisp. The features are centered around slime-mode, an Emacs minor-mode that complements the standard lisp-mode. While lisp-mode supports editing Lisp source files, slime-mode adds support for interacting with a running Common Lisp process for compilation, debugging, documentation lookup, and so on.

For much more information, consult the manual.

Quick setup instructions

1. Set up the MELPA repository, if you haven't already, and install SLIME using M-x package-install RET slime RET.

2. Add the following lines to your ~/.emacs file, filling in in the appropriate filenames:

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

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

If you'd like to contribute to SLIME, you will want to instead follow the manual's instructions on how to install SLIME via Git.

Contribs

SLIME comes with additional contributed packages or "contribs". Contribs can be selected via the slime-contribs list.

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.

License

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