DragonSpeak—DS for short—is the scripting language used in Furcadia Dreamweaving, and no dream can function at all without it. I've done a few projects with DS. Some are general experiments and methods of DragonSpeak coding that I have discovered, and one is basically a DragonSpeak search engine.
As of 2014, there are over 800 DragonSpeak commands, and finding them in either editor can be difficult. To help with this, I created a program that allowed the writer in question to enter certain criteria they wanted a line to meet, and they'd get a list of lines that would meet that criteria (or, at the least, find out whether or not such a line existed)
Originally part of the DragonSpeak Catalogue, these were split off into their own page to save on bandwidth, and so that they could be opened in individual tabs.
