I'm an iOS developer, and I haven't tried MacRuby yet, but it appears to be a good alternative to Objective-C. Assuming that MacRuby will be used on iOS devices in the future, perhaps the framework (and project) should be renamed before the v1.0 release. Some alternatives are: * AppleRuby.framework * CoreRuby.framework * HotRuby.framework (if HotCocoa is popular) * Ruby.framework (in Versions/?? subfolder) * RubyBridge.framework * RubyCocoa.framework (in Versions/B subfolder) * RubyFoundation.framework * RubyKit.framework Since you've recently moved to GitHub, and your "MacRuby: The Definitive Guide" book is probably nearing completion, I don't think this is likely to happen. But I thought it was worth suggesting, because choosing to rename after v1.0 (e.g. "iPhone OS 3.x" to "iOS 4") is worse. Cheers. P.S. I had a quick look at the MacRuby source code (commit 17be4634582ac22c418b). Here's a modest patch for "MacRuby.m": -- (id)performRubySelector:(SEL)sel -{ - return [self performRubySelector:sel withArguments:NULL]; -} +- (id)performRubySelector:(SEL)sel +{ + return [self performRubySelector:sel withArguments:NULL count:0]; +}
