Superior Lisp Interaction Mode for Emacs (Lisp-side server)
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 Lisp-side server, needed by the Emacs client (see package slime).
