cmd.auto_arg controls auto-completion of command arguments in PyMOL's command line. It is an array of dictionaries. When Pymol's console attempts to auto-complete the n-th argument of command abc, it will look at cmd.auto_arg[n]['abc'] (n starts from 0). This is a list with three elements. For arguments which do not have an entry in cmd.auto_arg, the default is to auto-complete file names.
- The first element is a lambda function which returns an Shortcut object. Shortcut object wraps the list of candidate strings, given to its constructor.
- The second element is a string, which describs the argument.
- The third element is a string, which will be added after autocompletion (postfix).
PYTHON EXAMPLE
cmd.auto_arg[0]['test']=[lambda: cmd.Shortcut(['abc','bcd']), '1st argument', ', ']
This code defines the auto-completion list for the first argument of command test. When you type 'test ' and press TAB, PyMOL will show you two candidates as:
parser: matching 1st argument:
abc bcd
If you type 'a' and press TAB again, PyMOL will complete it to "test abc, ". Note that ', ' is added.
Pre-defined lambdas
In most cases, you just want to complete from object names or setting lists. Then you don't have to write your own lambda function. Just use cmd.object_sc for choosing from objects.
cmd.auto_arg[0]['test'] = [ cmd.object_sc, 'object', '']
Or even simpler, borrow from one of the core commands:
# "extract" also uses cmd.object_sc in its first argument
cmd.auto_arg[0]['test'] = cmd.auto_arg[0]['extract']
Use cmd.selection_sc for setting names (like 'line_width'), cmd.map_sc for maps and cmd.repres_sc for representations ('sticks', 'lines', etc).
More Examples
The first argument of the save command auto-completes to filenames by default. If you want for example filenames and object names to auto-complete, use this (from pymol-users mailing list):
import glob
names_filenames_sc = lambda: cmd.Shortcut(cmd.get_names() + glob.glob('*'))
cmd.auto_arg[0]['save'] = [names_filenames_sc, 'filename or object name', '']
