Updating the configuration tables in leoConfig.py is straightforward, as
it turns out. Naturally, there are complications, all involved cached
settings, in one forma or another.
1. The easy cases: use properties.
There are about 60 or 70 places in the code where config settings are
stored in an ivar. Usually for readability, not for speed.
The solution (tested) is simple: rather than do:
self.setting_ivar = c.config.getX('a-setting-name')
Leo could define a property:
@property
def setting_ivar(self):
return c.config.getX('a-setting-name')
No other changes required. The existing code will test self.setting_ivar
exactly as before, but now any recent changes to the setting will have
effect.
I'll make these changes using a script.
2. The harder cases: use a reload_setting method in the affected classes.
Several subcommanders create tables on startup using config settings.
c.abbrevCommands is one such subcommander.
These classes should have a reload_settings method, called whenever
settings are dynamically reloaded.
Key bindings are the hardest case: the tables for key bindings are
mind-bogglingly complex. k.reload_settings would be a piece of work, but
in theory it should be possible.
