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.

The slime-mode programming environment follows the example of Emacs’s native Emacs Lisp environment. It also includes good ideas from similar systems (such as ILISP) and some new ideas.

SLIME is compatible with the following free Common Lisp implementations: CMUCL, SBCL, CCL, CLISP, ECL, ABCL.

This package contains the Emacs client, that will connect to the Lisp-side server (see package cl-swank).
