[kepler-dev] Determine whether -nogui was specified

[David Welker]

There is no really good way to do this at present.

If -nogui passed in as an argument, then that affects what is called  
(either org.kepler.KeplerConfigurationApplication or  
ptolemy.moml.MoMLCommandLineApplication) but unfortunately the fact  
that -nogui was passed in is not otherwise stored.

A hackish way to detect whether new -nogui was passed in that should  
work (I haven't tried it) would be to examine the current stack trace  
and see if either of the following is present.

org.kepler.KeplerConfigurationApplication.main(String[] args)

OR

  ptolemy.moml.MoMLCommandLineApplication(String[] args)

One of these classes is called if and only if -nogui was passed in as  
a command-line argument.

What are you trying to accomplish? Should we make it more convenient  
to determine whether -nogui has been passed in on the command line?
