macgem and previously installed gems
by Andy Park 07 Nov '10

07 Nov '10

I'm trying to get macirb that came with my new MacRuby installation to play nice ly with the existing .irbrc, where I'm using a lot of gems previously installed with gem. It looks like my gems aren't found by macirb because they were install ed with gem, so are not found / used by macgem. Would I really need to install a ll my gems using macgem in order to work with macirb using my existing .irbrc?

Frameworks Help
by Shaun August 02 Nov '10

02 Nov '10

Hi There, I am attempting to work with a framework provided by a USB device manufacturer and all of their method names start with capitols and I am wondering about the easiest way to access these methods through macruby. I remember reading somewhere about fixing the constants in Obj-C but I cannot locate the information. Does anyone have any suggestions as to how to remedy this? Should I rename every command in the framework? Thanks, Shaun

Understanding Pointer objects
by Mark Rada 26 Oct '10

26 Oct '10

Hi, I've been trying to play with using the Accessibility API to do some automated testing. From what I have researched, I have to use some C functions that often need a reference passed to the them. I am at a loss when trying to deal with Pointer objects. I've tried playing with them and googling it, but I just cannot figure out how to turn a pointer into a more useful type or to get what I want out of them. For example, I can start like this: framework 'Cocoa' unless AXAPIEnabled() # only works if I include the parenthesis puts 'Please enable Access for Assistive Devices first' exit 2 end mail = NSRunningApplication.runningApplicationsWithBundleIdentifier('com.apple.Mail').first mail_object = AXUIElementCreateApplication mail.processIdentifier names = Pointer.new :object AXUIElementCopyAttributeNames mail_object, names But then how do I get the values out of the names pointer? For reference, I found the functions in AXUIElement.h. Thanks, Mark

Mixing ruby code with Objective-C code within a Cocoa project...
by Frederick C. Lee 25 Oct '10

25 Oct '10

Greetings: I'm a MacRuby neophyte and wonder if I'll be able to mix Ruby with Objective-C, similar to the ability to write Objective-C++ code. I'm particularly interested in exploiting the power of Ruby's terse language to aid in Objective-C projects; preferably for iOS. Or... would I have to keep Ruby code in its own .rb file and pass data to/from ruby routines as parameters. Any info? Demo code? Regards, Ric.
