I am trying to detect when particular applications are launched.
Currently I am using NSWorkspace
, registering for the "did launch application" notification. I also use the runningApplications
method to get apps that are currently running when my app starts.
For most apps, the name of the app bundle is enough. I have a plist of "known apps" that I cross check with the name of that passed in the notification.
This works fine until you come across an app that acts as a proxy for launching another application using command line arguments.
Example: The newly released Portal on the Mac doesn't have a dedicated app bundle. Steam can create a shortcut, which serves as nothing more than to launch the hl2_osx
app with the -game
argument and portal
as it's parameter.
Since more Source based games are heading to the Mac, I imagine they'll use the same method to launch, effectively running the hl2_osx
app with the -game
argument.
Is there a nice way to get a list of the arguments (and their parameters) using a Cocoa API?
NSProcessInfo
comes close, offering an `-arguments' method, but only provides information for its own process...
NSRunningApplication
offers the ability to get information about arbitrary apps using a PID, but no command line args...
Is there anything that fills the gap between the two?
I'm trying not to go down the route of spawning an NSTask
to run ps -p [pid]
and parsing the output... I'd prefer something more high level.
