Jordan Hubbard brought up RubyInject, discussed at: http://rubycocoa.sourceforge.net/RubyInject RubyInject can be used with RubyCocoa to introspect on an application's objects, send messages to them, etc. It's possible that it can do even more with MacRuby, but I dunno. Anyway, I got brave and downloaded the RubyInject. That went OK, as did the xcodebuild step. I edited the inject.rb script into an mr_inject.rb variant (eg, removing RubyCocoa goo) and gave it a try. Sadly, it couldn't load dnssd. So, I tried installing dnssd as a gem. This worked OK, but MacRuby still didn't find it. Guessing that I needed macgem, I gave that a try. The results are documented on http://www.macruby.org/trac/wiki/MacRubyWithRubyInject If someone can help me get this sucker loaded and running, I promise to write it up on the wiki. Any takers? -r -- http://www.cfcl.com/rdm Rich Morin http://www.cfcl.com/rdm/resume rdm@cfcl.com http://www.cfcl.com/rdm/weblog +1 650-873-7841 Technical editing and writing, programming, and web development
