Up and running with Emacs, sbcl, and SLIME

While I normally program in Python, a part of me wants to quickly hack some lisp code every now and then. Especially during those long minutes when my automated tests are running.

I realized that long neglect had left me without a working lisp setup. Here is how I got it up and running again.

Step 1: Get rid of system lisp and slime

The version of sbcl and SLIME in my Ubuntu system is not recent enough for my liking. So I get rid of them:

$ sudo apt-get -y remove sbcl slime common-lisp-controller
$ sudo apt-get -y autoremove # get rid of packages we don't need anymore
$ sudo rm -rf /var/cache/common-lisp-controller

Step 2: Install common requirements

cd ~/
sudo apt-get update
sudo apt-get -y install emacs22
sudo apt-get -y install cvs
sudo apt-get -y install git-core
sudo apt-get -y install darcs
sudo apt-get -y install subversion
sudo apt-get -y install build-essential
sudo apt-get -y install autoconf
sudo apt-get -y install curl
sudo apt-get -y install sbcl
sudo apt-get -y install texinfo
sudo apt-get -y install tetex-bin
sudo apt-get -y install xloadimage

Step 3: Get clbuild

$ mkdir lisp
$ cd lisp
# for fresh install of clbuild
$ darcs get http://common-lisp.net/project/clbuild/clbuild
$ cd clbuild
# Or, to update existing clbuild
$ cd clbuild
$ darcs pull

Step 4: Get latest SBCL

$ ./clbuild update sbcl
$ cd source/sbcl
$ sh make.sh
$ cd doc/manual
$ make
$ cd ../..
$ echo > ~/.sbclrc
(require :asdf)
(push "/home/parijat/lisp/clbuild/systems/" asdf:*central-registry*)
^D
$

Step 5: Setup SLIME

$ ./clbuild update slime

Now, we need to add this slime configuration to our .emacs file:

(push "/home/parijat/lisp/clbuild/source/slime" load-path)
;; Common Lisp Mode
(setq inferior-lisp-program "/usr/local/bin/sbcl")
(add-to-list 'auto-mode-alist '("\\.lisp$" . lisp-mode))
(add-to-list 'auto-mode-alist '("\\.cl$" . lisp-mode))
(add-to-list 'auto-mode-alist '("\\.asd$" . lisp-mode))
(require 'slime)
(slime-setup)
(eval-after-load "slime"
 '(progn
    (setq slime-complete-symbol*-fancy t
          slime-complete-symbol-function 'slime-fuzzy-complete-symbol
          slime-when-complete-filename-expand t
          slime-truncate-lines nil
          slime-autodoc-use-multiline-p t)
    (slime-setup '(slime-fancy slime-asdf))
    (define-key slime-repl-mode-map (kbd "C-c ;")
      'slime-insert-balanced-comments)
    (define-key slime-repl-mode-map (kbd "C-c M-;")
      'slime-remove-balanced-comments)
    (define-key slime-mode-map (kbd "C-c ;")
      'slime-insert-balanced-comments)
    (define-key slime-mode-map (kbd "C-c M-;")
      'slime-remove-balanced-comments)
    (define-key slime-mode-map (kbd "RET") 'newline-and-indent)
    (define-key slime-mode-map (kbd "C-j") 'newline)))
(add-hook 'lisp-mode-hook (lambda ()
                           (cond ((not (featurep 'slime))
                                  (require 'slime)
                                  (normal-mode)))
                           (indent-tabs-mode nil)
                           (pair-mode t)))

Note: pair-mode is a nice package for inserting balanced parentheses, quotes, braces and square-brackets, etc., which I installed earlier by hand.

Now we can launch emacs, and start slime with “M-x slime”.

Caveat

For some reason, after doing the above, slime would still not start. Doing a “M-x slime” would throw me into the sbcl debugger with the error message that sbcl could not find “/usr/share/common-lisp/systems/slime/swank-loader.lisp”, or something like that (I could be wrong about the exact path). After much head-scratching (and grepping my ~/lisp directory), I figured out I had to change the emacs customization variable slime-backend. This can be done by doing “M-x customize-group RET slime-lisp RET” and changing the value of “Slime Backend” to simply “swank-loader.lisp” (the file should be in the same directory as “slime.el”). We can also give an absolute path to the file. I found that the value of this variable was set wrongly (an artifact of using apt-get installed slime, I guess) and hence sbcl was not able to load the correct file.

    Useful, thanks. I’ve recently decided to move closer to the head, so to speak and was looking for this info.

    By-the-way, your step 1 removes sbcl but step 2 adds it back again. Therefore you don’t really need to do step 1!! It turns out that you can’t build SBCL without already having a lisp installed so perhaps step 1 should be step 6?

    I get the following when i run sh make.sh…

    //building cross-compiler, and doing first genesis
    make-host-1.sh: 31: sbcl: not found
    Command exited with non-zero status 1

    For some reason SBCL dit not install with apt-get -y install…it downloaded the packages but the actual install seemed not to have happened..i re ran apt-get install sbcl and it just unpacked and installed ok. Then I used “clbuild compile-implementation sbcl” instead of make. According to the guys at lisp.irc its the better way.

    Thought I would just share it with you.

    Thanks for this! I had the exact same problem with an incorrect path to swank-loader.lisp in emacs… After much head-scratching and googling, you saved the day.

    there is no .emacs file in my ~/ and when I create one. emacs directly starts from slime . there is no need to do M-x slime. How can I use it by M-x ?

    • parijatmishra  On December 21, 2009 at 10:58 am

      Your .emacs should have:


      (require 'slime)
      (slime-setup)

      but NOT (IIRC):


      (slime-start)

      When you call ‘M-x slime’, it calls ‘slime-start’. Unfortunately, I don’t have a working setup right now to verify.
