Post Code

One recurring complaint is that nobody talks about code on /prog/. So everyone write go and write some code, any code, that does something, anything, and post it. A small explanation wouldn't go amiss either.

Terrible!
Please get Emacs, or some Lisp IDE (if you really don't like Emacs). They are able to automatically indent Lisp code. Of course, after having used them for so long, I do know all the indentation rules myself (sometimes I even add rules for my own macros), but I wouldn't indent manually - indentation is there to help you quickly understand what some code is doing, it's quite helpful in lisp as indentation is used to serve as a visual cue as to the purpose/functionality of the code, things which pure syntactic sugar does for you in other languages.

Example proper indentation for your code:

(defun factorial (num)
  (if (> num 1)
      (* num (factorial
              (- num 1)))
      1))
;;; or
(defun factorial (num)
  (if (> num 1)
      (* num (factorial (- num 1)))
      1))


If you MUST know the rules explicitly, here's some hints for CL ( http://www.labri.fr/perso/strandh/Teaching/MTP/Common/Strandh-Tutorial/indentation.html ) and Scheme ( http://mumble.net/~campbell/scheme/style.txt )
