SLIME: The Superior Lisp Interaction Mode for Emacs
SLIME is a Emacs mode for Common Lisp development. Inspired by existing systems such
Emacs Lisp and ILISP, we are working to create an environment for
hacking Common Lisp in.
This frugal page is an invitation to learn more about what's going on.
- slime-mode: An Emacs minor-mode to enhance lisp-mode with:
- Code evaluation, compilation, and macroexpansion.
- Online documentation (describe, apropos, hyperspec).
- Definition finding (aka Meta-Point aka M-.).
- Symbol and package name completion.
- Automatic macro indentation based on
- Cross-reference interface (WHO-CALLS, etc).
- ... and more.
- SLDB: Common Lisp debugger with an Emacs-based user interface.
- REPL: The Read-Eval-Print Loop ("top-level") is written in Emacs Lisp
for tighter integration with Emacs. The REPL also has builtin "shortcut" commands
similar those of the McCLIM Listener.
- Compilation notes: SLIME is able to take compiler messages and annotate
them directly into source buffers
- Inspector: Interactive object-inspector in an Emacs buffer.
SLIME works with GNU Emacs versions 21 and later, and with XEmacs version 21 on
Unix, OSX, and Win32.
The currently supported Common Lisp implementations are:
- CMU Common Lisp (CMUCL)
- Steel Bank Common Lisp (SBCL)
- Clozure CL (a.k.a. OpenMCL)
- Allegro CL
- Scieneer CL
- Corman CL
We recommend that you use the CVS version.
You can download
a cvs snapshot in tarfile format.
You can check out the latest version with:
cvs -d :pserver:anonymous:firstname.lastname@example.org:/project/slime/cvsroot co slime
We have a manual (as
pdf) that explains what SLIME can do and how to use it.
screencasts and tutorials
Various tutorials about SLIME are available on the 'net:
- Marco Baringer's SLIME video (150MB, 55 minutes).
- Yusuke Shinyama's SLIME on Linux (1.3MB).
- Fernando Lopez-Lezcano wrote an excellent tutorial for SLIME
and CL-Music. The original document is no longer accessible but you
can find most of it in Bill Clementson's Blog.
You can report bugs at the bugtracker.
mailing list is used for all
SLIME discussions. This is where to ask questions, send patches, and generally participate in
The mailing list is also available via
as group gmane.lisp.slime.devel both via a web

SLIME is an Extension of SLIM, which was
written by Eric Marsden in mid-2003. Luke Gorrie and Helmut Eller took over development to
create SLIME as a traditional "open-source project." Since then the hacking has continued at a
rapid pace as many more hackers joined the fray.
A (hopefully) complete list of code contributors appears in the SLIME manual.
