One of the things I'm working on in my spare time is rewriting and extending DXR. I'm adding more static analysis info to the data, adding a "document" style vs. "web app" interface, ripping out glimpse/MXR, making it easier to get at type info from the UI, and redoing the front-end in Python (so Andrew can't continue to go around claiming I hate Python). It's going to be awesome, but first...
Yesterday I was trying to write a unittest for how I process typedefs for function pointers, and I couldn't glean how Dehydra was reporting the underlying type. As usual #mmgc had my back, and Benjamin disappeared into some back room and reappeared with this amazing print-out of Dehydra's JS objects, returned by analyzing my code. "Where did you get that output?" I asked. "Oh, I just do this, this, and this".
Well, for my own purposes I decided to turn his method into a little web app: Dehydra Web. It takes your C++ code fragment (must compile) and runs it through Benjamin's dump-dehydra-data.js before cleaning-up the output.
It's not likely to replace Twitter as the next great web app, but if you're working on Dehydra, it's invaluable as a debugging tool in order to quickly test your understanding for an analysis script.
