My last update was back in January: http://lists.racket-lang.org/dev/archive/2010-January/002045.html
GRacket2 wasn't done by May, obviously. I still like to think that we could have something working within a few months, though. The Racket switch contributed to the delay, but eventspace issues were less easy to solve than I had hoped. In particular, using multiple OS threads doesn't help; it turns out that modern GUI toolboxes provide even less support for multiple threads than old toolboxes. I have to stick with my old bag of complicated tricks. The sources have moved here, for now: http://github.com/mflatt/gr2/ Beware that I occasionally sync with the main Racket repo by pulling with --rebase and then pushing with --force. That rewrites history in the `mflatt/gr2' repo so that the GRacket2-specific changes extend the main repo. If you build on Mac OS X or Windows, beware that `make' downloads some pre-built libraries for Cairo, Pango, etc. (If you really want to build them yourself for Mac OS X, see "racket/src/mac/README.txt" for hints.) For X11 platforms, you just need Gtk2 development packages installed. Most widgets are implemented enough to instantiate, but there are lots of details to be filled in. The drawing library is fairly complete and getting very close to the same output as the old drawing library (relative to the old library's variation across platforms). DrRacket starts, but it's not at all usable. Slideshow programs mostly render correctly. We still need an XPM parser, if anyone is interested in volunteering to implement one. It's also possible that a Gtk2 or Cocoa expert could help finish up the windowing classes in "collects/mred/private/wx".
