Common LISP Code Samples
Below is a piece of lisp-code, which implements insertion, find and deletion in red-black-trees. The algorithm for insertion is taken from a C source I found in the internet, the deletion algorithm I developed originally. The program contains some testbed-code which you can delete as it is probably not of much use elsewhere.
There was a program A with CLOS originally, but it is not presented here anymore, as it is not maintained any longer. Program B is implemented with structs, leading two a fourfold increase in execution speed over version A. At the moment only Program B contains the find and deletion code.
A LL(1) Parser generator
A simplistic LL(1)-Parser generator is currently under development. It can be found in parser-gen.lisp
Exporting Opera bookmarks to Netscape/Mozilla
bookmarkprocess.lisp contains functions for importing Opera bookmarks, selecting subsets from them and exporting to Netscape.

A small wish in big print:
If you do more with the code here than just glance over it:
