Hi, Good catch, the Method structure is likely clashing with the Ruby Method class :) I'm not sure if we should try to make it work, as it's surely an edge case. Maybe #load_bridge_support_file should accept a Module object where the constants should be defined, as a second, optional, argument? As for calling the runtime from MacRuby, I think that most runtime functions are already used in MacRuby somehow and exposed through the Ruby API. For example, #methods(true, true) calls class_copyMethodList(). Laurent On Jan 6, 2011, at 12:17 PM, kyossi wrote:
Hi,
MacRuby support bridgesupport .You can call any C-function, See "Accessing Static APIs" in http://www.macruby.org/documentation/tutorial.html
but..I cannot load bridgesupport file for runtime.h
$ cd /Developer/SDKs/MacOSX10.6.sdk/usr/include/objc $ gen_bridge_metadata -c '-I.' runtime.h > ~/Desktop/runtime.bridgesupport $ macirb irb > load_bridge_support_file "/Users/kyossi/Desktop/runtime.bridgesupport" NameError: Method is already defined
It seems like one line in runtime.bridgesupport conflict with Method class in ruby. <opaque name='Method' type='^{objc_method=}'/>
When I tried with comment out above line, load_bridge_support_file() succeeded and could call some function.
irb > load_bridge_support_file "/Users/kyossi/Desktop/runtime.bridgesupport" => main irb > class_getName(NSString) => "NSString"
I could not go further.

I'm guessing this is documented somewhere but have not been able to find it yet... How can objective C runtime methods such as class_copyMethodList be called from MacRuby? Thanks! -Garett
