It should be possible to create a macirb session that (like script/console, in Rails) loads up an app's code and then lets the user interact with it, via the keyboard. I find console very handy for exploration, so I think this would be, too. Going a bit further, what about setting up a macirb session that lets the user interact dynamically with MR? For example, start up MR, play with the GUI, then go over to the macirb session to look at the results, overload methods, etc. It may be that Xcode already has this sort of functionality (if so, please point me to it :). I suspect, however, that Xcode isn't really built to take advantage of dynamic languages. So, what mashups would be possible and interesting? -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
