You could simply piggy-back on the Dabo PreferenceManager built into
all Dabo classes. The general pattern is:
(setting)
pm = self.PreferenceManager
pm.lunch.entrees = ["steak", "salmon", "tofu"]
(getting)
pm = self.PreferenceManager
for entree in pm.lunch.entrees:
print "You may eat %s" % entree
All the saving happens pretty automagically. Just use standard
dotted-object notation to set attributes of the ProjectManager, nesting them as
much as needed. Later you can retrieve those values by just referencing the
same path. Every object can have its own BasePrefKey value, which is the root
of the path, so that you can keep your saved values separate.
