So, how do I get Textmate to use MacRuby, a branch of 1.9.2, instead of the default Ruby in OSX, 1.8.7? Simpler answers: Install MacRuby Go to TextMate->Preferences->Advanced->Shell Variables and add a variable named TM_RUBY set to /usr/local/bin/macruby .

Java has a

The nice thing is that you can use "Design Patterns in Ruby" as your primary text and the other 2 as reference texts (although you should definitely read "The Ruby Programming Language" all

I have some basic familiarity with Objective-C, but prefer Ruby, so I'm thinking of playing around with MacRuby. Is it possible to use MacRuby to develop applications for the Mac App Store, or do I have to use Objective-C? (Note that I don't care so much about iOS/the iPhone and iPad store right now, just the Mac OS X app store.) Short answer: Yes, you can, technically, build such an app. You need to revisit the store guidelines to know what requirements must be met to submit to the various stores. This comes up sporadically; beyond the guidelines that @NSResponder mentioned, the reality is
