I've been playing around with the EmbeddedMacRuby project.
I'd like to be able to:
a) Run user scripts (written in Ruby) from within a cocoa application (so
far, so good)
b) Call ruby functions from objective-c
c) Call my private objective-c API's from Ruby functions and scripts
I'm having problems with b & c.
I'm assuming that the mechanism for b & c is different than that used to
execute a Ruby script. It looks like gen_bridge_metadata script should be used
to make my objective-c class and methods visible to Ruby.
However, when I try to run gen_bridge_metadata on a simple header file that
declares an objective-c class and a couple of test methods, gen_bridge_metadata
doesn't produce anything in the output file other than the 3 lines of header
information...
1 <?xml version='1.0'?>
2 <!DOCTYPE signatures SYSTEM
"file://localhost/System/Library/DTDs/BridgeSupport.dtd">
3 <signatures version='0.9'/>
I'm running the tool as follows (I've also tried a number of other variations):
gen_bridge_metadata -c '-I.' MyController.h -o
MyController.bridgesupport
I'm running 10.6.4, ruby 1.8.7 , with macRuby 0.7 installed.
I also have ruby1.9 installed.
Questions...
1) Shouldn't this produce at least simple output with information regarding the
class and method calls?
2) Is there some documentation (or examples) somewhere that shows how to set
things up properly to enable items b & c? I haven't been able to find anything
in the documentation, or on the web that actually demonstrates how to do this,
and gen_bridge_metadata doesn't seem to be cooperating.
Any pointers or suggestions welcome.
Thanks.
