It looks like Andrey wants his script to be able to interpret command
line arguments. Unfortunately, PyMOL doesn't enable this in a
consistent way, since Launching under Windows (embedded Python) is quite
different than unix (non-embedded Python).
With embedded Python, arguments aren't making it to sys.argv. Instead,
they are being passed straight from C into PyMOL's invocation routine.
I will fix this in the next version by reassigning them to sys.argv, but
you can do this immediate by inserting
import sys
sys.argv = copy.deepcopy(argv)
Directly under "def parse_args(argv):" (line 79) in
PyMOL/modules/pymol/invocation.py.
I'd also like to provide a means by which certain can be ignored by
PyMOL and be available directly to Python scripts in PyMOL.
Here is my proposal:
Ignore any arguments after a double-hyphen ("--") sentinel. For
example:
pymol -c myscript.py -- -pymol -will -ignore -these -arguments
pymol -c myscript.py -- -your -script -interpret -them -instead
Any objections?
