One way would be to add some initialization test code to the main module
to set sys.argv. Another way is to call idle from the command line:
$ /usr/local/bin/idle2.6 -h
USAGE: idle [-deins] [-t title] [file]*
idle [-dns] [-t title] (-c cmd | -r file) [arg]*
idle [-dns] [-t title] - [arg]*
-h print this help message and exit
-n run IDLE without a subprocess (see Help/IDLE Help for
details)
The following options will override the IDLE 'settings' configuration:
-e open an edit window
-i open a shell window
The following options imply -i and will open a shell:
-c cmd run the command in a shell, or
-r file run script from file
-d enable the debugger
-s run $IDLESTARTUP or $PYTHONSTARTUP before anything else
-t title set title of shell window
A default edit window will be bypassed when -c, -r, or - are used.
[arg]* are passed to the command (-c) or script (-r) in sys.argv[1:].
Examples:
idle
Open an edit window or shell depending on IDLE's configuration.
idle foo.py foobar.py
Edit the files, also open a shell if configured to start with
shell.
idle -est "Baz" foo.py
Run $IDLESTARTUP or $PYTHONSTARTUP, edit foo.py, and open a shell
window with the title "Baz".
idle -c "import sys; print sys.argv" "foo"
Open a shell window and run the command, passing "-c" in
sys.argv[0]
and "foo" in sys.argv[1].
idle -d -s -r foo.py "Hello World"
Open a shell window, run a startup script, enable the debugger,
and
run foo.py, passing "foo.py" in sys.argv[0] and "Hello World" in
sys.argv[1].
echo "import sys; print sys.argv" | idle - "foobar"
Open a shell window, run the script piped in, passing '' in
sys.argv[0]
and "foobar" in sys.argv[1].

Right-click (control-click) menus currently don't work in IDLE on OS X.
I hope to get that fixed eventually.
