[MacRuby-devel] Quartz 2D Graphics problem

[Mark Rada]

Adding some Objective-C code could be done with a framework as suggested, or by creating a bundle. The bundle process is essentially the same as creating a C extension for Ruby. Any MacRuby project with a C extension could be used as an example:

https://github.com/pieter/macruby-bundle-example
https://github.com/Marketcircle/AXElements/tree/master/ext/accessibility/key_coder
https://github.com/alloy/ObjectiveBacon/tree/master/LanguageBindings/MacRuby/ext

You can then simply "require 'bundle'" the bundle file that is compiled.
