Wow, the lxr code is a lot nicer than the old stuff. I was working on getting some more color into the output when someone pointed me to the new version, so I checked that out. It works with an RDBMS now (although you can still use db). The developers are working with Postgresql, but since I already had mysql installed, I tried to get it to work with that.
Sent patch to the mailing-list after I succeeded. Now I'm thinking about how to best encapsulate the functionality of lxr in some bonobo component thingie, so my development environment will provide it's editor with a nice way to get those click-to-go-to-the-function-defitition thingies, etc.
Am also thinking it might be cool to add a table with RDP links in there, so while browsing gtk+/gnome code, you'll be able to look up what that function does with just one click.
