Here’s yet another indentation hack that I came up with recently. All the work done by Nikodemus on the Slime indentation contrib is pretty cool, especially the notion of indentation style (though I wish the styles were Custom variables, but that is another story). I tend to use indentation styles for global, maybe collaborative preferences, but on several occasions however, I find that this approach has a couple of drawbacks.

Update: since the original publication of this article, Nikodemus Siivola and I have done some more work on various other aspects of Common Lisp indentation, and I must say that the result is pretty satisfactory. Nikodemus has merged all the changes into Slime, and I have done so for XEmacs. If you’re an XEmacs user, you don’t need to use the slime-indentation contrib to get these improvements. Simply upgrade the “prog-modes” package and load cl-indent.el.
