Subject: Re: [PyMOL] Syntax for cmd.auto_arg.update
Hi Carsten,
Below is what I learned by reading codes and experimenting.
The relevant code is in parser.py, cmd.py and shortcut.py.
Please correct me if I am wrong.
+++++++++++++++++++++
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.
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).
Example:
cmd.auto_arg[0]['test']=[lambda: cmd.Shortcut(['abc','bcd']), '1st
argument', ', ']
will setup the autocompletion list of 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, ". Please 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', '']
Use cmd.selection_sc for setting names (like 'line_width'),
cmd.map_sc for maps, cmd,repres_sc for representations
(sticks, lines, etc).
By the way, update is another way to set values to Python's Dict.
auto_arg[0]['test'] = [some, thing, s] is same as
auto_arg[0].update([('test', [some, thing, s])]).
Best regards,
Takanori Nakane
