Any pointers? I don't see anything that could help me here but that document is
quite confusing anyway with so many things deprecated...

Don't worry, I'm pretty much done already and it's working fine. 
And I'm not the only one who is using a custom solution. Check out
popular toolkits like SDL, GLFW, wxWidgets... they all do it one or
another. And even Apple says that it's legit:

"Override run if you want the app to manage the main event loop differently
than it does by default. (This a critical and complex task, however, that you
should only attempt with good reason.)"

I just wish there'd be some more information on how exactly this "critical
and complex task" should be implemented in practice ;)

Whatever you do, you still have to pull the incoming events, else you Apple 
Event won’t be dispatched. As the canonical way to do that is though NSApp, I 
don’t now if this is possible.

Perhaps through LaunchServices, or by implementing its own AppleEvent handler 
for the ‘odoc’ event.

I do still feel that your attempt to build this 3rd-party code wrapper by 
avoiding the normal Cocoa application/event loop is a mistake. You’re going to 
run into one problem after another by going completely against the grain of the 
framework like this.

Get file argument

[Andreas Falkenhahn]

When double-clicking a document file that is to be opened with my app,
the path to this file isn't passed in argv[] but can be obtained by 
implementing "openFile" in the NSApplicationDelegate.

Is there also a way to get the file argument without having an NSApp,
i.e. can my program somehow obtain the file argument *before* creating
the NSApp object or is that impossible?
