I need to write an app whose purpose is to drive other apps, using

needs to be set up in order for NSAppleScript to work. I suspect it
needs at
least NSRunLoop event processing; I wonder if it might also need an
NSApplication around.
Past use of NSAppleScript has revealed that it's somewhat "quirky"
about
event handling, in that what looks like a blocking synchronous call
(executeAndReturnError), seems to allow the event loop to keep
processing
while it's waiting for a response.
And if it's too much of a pain in the neck, I'll just live with what I
already know how to do easily: a "GUI" that consists of a status
window and
a "Quit" menu item ;-)
Add the LSUIElement key to the Info.plist and it will launch without a
dock icon or a menu. You can then safely call
[NSApplication sharedApplication] from within your application to
connect to the window server (so you can use AppKit and other
frameworks). Then just do [NSApp run] to start the run loop and the
event loop and treat it like normal... no need to create a window
(although you could load one if you
ever had a need to).
HTH, Jason
