BGMApp now disables BGMDevice's volume and/or mute controls if the
output device selected in BGMApp doesn't have matching controls. This
prevents the controls from being presented to the user when they don't
do anything.
In BGMPlayThrough, wait much longer for our IOProcs to stop themselves
before assuming something's gone wrong. In testing, rapidly changing
between output devices with and without controls while playing audio
would occasionally cause one of the IOProcs to take too long to stop
itself.
Also adds some basic scriptability, mainly so UI tests can use
AppleScript to check BGMApp's state that would be complicated to check
otherwise. (In this case, to check which output device is selected.)
Fixes#101.
The UI tests run with clean user defaults, but BGMDevice and Scripting Bridge
still need to be mocked/stubbed out. That also means that the UI tests can only
run if BGMDriver is installed and that changes to BGMDriver's state made during
the tests will persist.
The names of the data source(s) for a device are generally the names
intended to be shown to the user, since the OS X volume menu, System
Preferences, etc. use them.
A menu item is now added for each data source of each output device,
rather than one per device.
Also adds some macros/functions for casting values to __nonnull.
Resolves#59.
- Destroy the Scripting Bridge application object for a music player
when that music player isn't running.
- Move the UI code for the auto-pause menu item into its own class.
- Add a User Defaults class to BGMApp.
- Enable some more warnings for the BGMApp project.
