Download

  1. Common LISP.
  2. Emacs – editor / “IDE”.
  3. Quicklisp – key LISP library that allows to download and maintain other libraries with ease.

Install

  1. Install Emacs.
    • Unpack contents of Emacs archive.
    • Add Emacs directory (e.g. C:\ntemacs24\bin) to your PATH system variable.
  2. Create HOME directory.
    This is necessary to avoid problems with home directory recognition by lisp.
    • Create the C:\HOME directory.
    • Add a new system variable with Name HOME and Value C:\HOME.
  3. Install CLISP.
    • Create an easy-to-reach, easy-to-use directory. I use C:\lisp.
    • Install CLISP in that directory.
      NOTE: the latest version at the time of writing is 2.49, but I’m having trouble getting it to load SLIME properly (see below), so version 2.48 it is. (file clisp-2.48-win32-mingw-big.exe).
    • IMPORTANT:
      Installer of the version 2.48 is faulty.
      To fix this problem, copy svm.dll out of clisp-2.48/libsvm directory into clisp-2.48/full.
  4. Install quicklisp.
    • Place quicklisp.lisp into C:\lisp
    • Run CLISP and execute the following:
    (load "C:/lisp/quicklisp.lisp")
(quicklisp-quickstart:install :path "C:/lisp/quicklisp/")
(ql:add-to-init-file)

  5. Install SLIME – Superior Lisp Interaction Mode for Emacs, an Emacs extension to make lisp development seamless.
    In the CLISP console execute:

    (ql:quickload "quicklisp-slime-helper")
  6. Configure Emacs.
    • Launch Emacs.
    • Type Ctrl-x, then Ctrl-f.
    • Enter ~/.emacs in the prompt at the bottom of the window.
    • Add the following lines to the file:
    (setq inferior-lisp-program "clisp.exe")
(load "C:/lisp/quicklisp/slime-helper.el")
    • Type Ctrl-x, then Ctrl-s to save the file.
