Re: [Rubycocoa-talk] Calling Accessibility AX* functions

[Laurent S. <lsa...@ap...>]

Hi Patrick,

Unfortunately, HIServices is not covered yet by bridge support. I  
suggest you to file an Apple bug (http://bugreporter.apple.com) for  
this and request the file to be created in the future.

In the meantime, you can either generate a file by yourself (see  
gen_bridge_metadata(1) for some help), manually bind the functions  
using a C extension, or use the dynamic linker (dyld) at runtime.

If you want to go with the gen_bridge_metadata way, the following  
should work (untested though)

$ sudo mkdir /System/Library/Frameworks/ApplicationServices.framework/ 
Frameworks/HIServices.framework/Resources/BridgeSupport
$ sudo gen_bridge_metadata -f /System/Library/Frameworks/ 
ApplicationServices.framework/Frameworks/HIServices.framework -c '- 
framework ApplicationServices -F/System/Library/Frameworks/ 
ApplicationServices.framework/Frameworks' -o /System/Library/ 
Frameworks/ApplicationServices.framework/Frameworks/ 
HIServices.framework/Resources/BridgeSupport/HIServices.bridgesupport
$ irb -r osx/cocoa
 > OSX.require_framework '/System/Library/Frameworks/ 
ApplicationServices.framework/Frameworks/HIServices.framework'
 > OSX::AXUIElementCopyElementAtPosition(...)

HTH,
Laurent
