Script Bridge

Scripting Bridge is a technology that you can use in PyObjC and RubyCocoa scripts to communicate with scriptable applications—that is, applications with scripting interfaces compliant with the Open Scripting Architecture (OSA). With Scripting Bridge, RubyCocoa and PyObjC scripts can do what AppleScript scripts can do: control scriptable applications and exchange data with them. The Scripting Bridge framework implements a bridge between OSA and the Objective-C runtime. It reads the scripting definition of applications and dynamically populates the Objective-C namespace with objects and methods representing the various items it finds (scripting objects, elements, commands, properties, and so on). RubyCocoa and PyObjC are also bridges to the Objective-C runtime and thus have access to everything in a program’s namespace, including Scripting Bridge–created objects.
