Extend is an API-only function which binds a new external function as a command into the PyMOL scripting language. In other words, when you write a function and want PyMOL to recognize the new command, you
extend the command into PyMOL. Once extended, the function name is recognized like other function names (example below). Typically,
extend is the last line of a PyMOL script.
PYMOL API
cmd.extend(string name,function function)
PYTHON EXAMPLE
def foo(moo=2): print moo
cmd.extend('foo',foo)The following would now work within PyMOL:
PyMOL>foo
2
PyMOL>foo 3
3
PyMOL>foo moo=5
5
PyMOL>foo ?
Usage: foo [ moo ]
NOTES
For security reasons, new PyMOL commands created using "extend" are not saved or restored in sessions.
You may want to set auto_arg to enable auto-completion for your command's arguments.
