There is a way :-)
- You modify the project to link against MacRuby.framework
- You copy the main.m and rb_main.rb files from an existing MacRuby
application (you will override the existing main.m file here, but
rb_main.rb will be a new file)
- You add a build phase that copies all .rb files into the Resource
directory of the application bundle
- Then you can start porting the code. You can start by converting a
file into MacRuby (MyClass.[m|h] -> MyClass.rb), then remove the C/
Objective-C files from the project.
I did this process quite a few times when porting some Objective-C
sample code into RubyCocoa/MacRuby. I don't think I forgot to mention
