Trying to learn OS X application scripting with Ruby and appscript, but have run into a problem with a small example meant to demonstrate the various methods of getting OS X application objects. Code: #!/usr/bin/ruby # this ruby script demonstrates different methods of getting OS X application # objects using appscript (of class Appscript::Application). The method new of # this class is private; thus we use another method called Appscript.app. This # calls Appscript::GenericApplication.new for you and generates an instance of # class Appscript::Application. # by_name # by_id # by_creator # by_pid # by_url require 'rubygems' require 'appscript' require 'osax' ## by_name Appscript.app.by_name("iTunes") # may be shortened thus: Appscript.app("iTunes.app") ## by_id puts OSAX.osax.info_for( MacTypes::Alias.path("/Applications/iTunes.app"))[:bundle_identifier] #=> com.apple.iTunes That last line (trying to do it by bundle ID) throws this error: Code: /Library/Ruby/Gems/1.8/gems/rb-appscript-0.5.3/lib/osax.rb:153:in `initialize': OSAX::ScriptingAddition can't dynamically retrieve scripting addition terminology within a 64-bit process. (RuntimeError) from /Library/Ruby/Gems/1.8/gems/rb-appscript-0.5.3/lib/osax.rb:102:in `new' from /Library/Ruby/Gems/1.8/gems/rb-appscript-0.5.3/lib/osax.rb:102:in `osax' from app_objects.rb:29 FWIW, I run the x64 kernel in 10.6.5. This is NOT school, BTW. Just doing this for fun. Thanks!
