Software

C/C++

• CDargs - Bookmarks and browser for the shell builtin cd

Gnu Emacs

My newer contributions to the Emacs Lisp World are developed in Gnu Emacs Version >= 22. So XEmacs probably won't work for these

• taskjuggler-mode - Replacement for the taskjug.el shipping with taskjuggler

(X)Emacs

• highlight-context-line - Highlight the last visible line
• swiss-move - Moving with decreasing stepsize
• mouse-focus - focus follows mouse for XEmacs windows
• mtorus - Navigating positions stored on a torus
• tex-letter - Inserting LaTeX letter templates with a menu
• track-scroll - Dragging buffers with the mouse
• linmag-mode - Writing articles for the Linux Magazin
• bravegnuworld-mode - HTML plus comments for proof-reading.
• multiselect - Select non-contiguous regions and yank them later.

Work in Progress

These are raw versions of emacs libraries or previews or whatever. Try to use them if you want to, clean the up if you find the time and send them back ;-)

• active-menu.el - One more line of Screen Real Estate (Gnu Emacs and XEmacs)
• watch-sexp.el - Continuously updating buffer with evaluated sexps

Common Lisp

• cl-ipc - Very simple IPC message queue handling.

Ruby

• Femto - A very small bulletin board for cooperative environments.

Perl

• W3Make Publishing - XML Webpublishing (dead)
• Regular Expression Move - renaming files with regexps (pre-alpha)
• LaTeX2Wiki - Converting LaTeX to wiki syntax (alpha)
• AI::GA - Generalised Perl module for Genetic Algorithms (very old, dunno whether this still works)

Sawfish

• dot-sawfishrc - My stout old ~/.sawfishrc
• Sawfish Runner - Run programs with menu and completion
