Note: strictly, the AppDelegate doesn't appear as part of the scripting model,
|
|
so this file is rather unlike the other Object+Scriptability.swift files.
|
|
However, the AppDelegate object is the de facto scripting accessor for some
|
|
application elements and properties. For, example, the main window is accessed
|
|
via the AppDelegate's MainWindowController, and the main window itself has
|
|
selected feeds, selected articles and a current article. This file supplies the glue to access
|
|
these scriptable objects, while being completely separate from the core AppDelegate code,
