Save settings

save_settings is a prototype implementation to save all settings with non-default values to a file.

By default settings will be stored to ~/.pymolrc-settings.py which is automatically recognised and loaded by PyMOL on startup. You have to manually delete the file if you no more want those settings to be loaded.

This answers a feature request on sourceforge.

Usage

save_settings [ filename ]

The Script

from pymol import cmd

def save_settings(filename='~/.pymolrc-settings.py', quiet=1):
    '''
DESCRIPTION
 
    Dumps all settings with non-default values to ~/.pymolrc-settings.py
