As far as I know, Elliott isn’t using Espresso any more (switched to Linux, last I heard). I haven’t heard anything about anyone else taking the Ruby sugar under their wing, although people have batted it around from time to time.
I’d like to continue work on the Ruby sugar - just haven’t had much time to add to it lately. My first goal is codesense - I’ve been working on Rails codesense for my Rails sugar, but if Elliott isn’t maintaining the Ruby sugar anymore, then maybe I’ll start with ruby codesense and then do the Rails. I’m a little stuck though on what’s the best approach for codesense (see other question in forum).
This topic is pretty dead, but on the bright side I’ve been working on a fork of elliottcable’s ruby.sugar here. Navigator/code folding is working for most things, I added array and hash support, though at the moment this does cause blocks to occasionally break. The main problem is still /regex/ handling, but it has improved a lot!
