As Todd Geist quoted here earlier, in the Dictionary entry for "$" it says:
If you start up the application from the command line (on OS X,
Unix or Windows systems), the command name is stored in the
global variable $0 and any arguments passed on the command line
are stored in numbered variables starting with the $ character.
For example, if you start the application by typing the following
shell command:
myrevapp -h name
then the global variable $0 contains "myrevapp" (the name of the
application), $1 contains "-h", and $2 contains "name".
In my tests here, it seems this is only partially correct: $0 contains
the app name from the command line ("myrevapp" in their example), but $1
contains the "name" portion after the "-h" option flag, and the flag
itself does not appear in any $ variable.
I have an app in which I'd like to have two different behaviors,
depending on whether it's being run from the command-line or as a GUI.
This would be easy if the engine worked as described in the Dictionary
so I could easily detect if the user launched it with "-ui", but it
seems the option flags are not being passed to the application, though
everything that doesn't begin with "-" is.
So my question is two-fold:
1. I've tested this on Windows and Linux and get identical behavior, in
which the "-" flags aren't present in the "$" vars. Can anyone here
confirm this on Linux, Win, or OS X?
2. If this is indeed a documentation bug and what I see in my tests is
what happens for everyone, how can I determine whether the app was
launched with "-ui" or not?
