Namespace

To be able to store persistent settings you have to set an application name. This will create an application configuration file in an OS dependent location.

app.name = "example" # stores settings in `HEPHY/example.conf` (location is OS depended)

Access

Settings can be accessed using the applications settings property. Changes will be stored automatically on application exit.

>>> app.settings["spam"] = 42
>>> app.settings.get("spam")
42

Mixins

Inherit from class SettingsMixin to provide access to persistent application settings from within custom classes.

from comet.settings import SettingsMixin

class Custard(SettingsMixin):
    @property
    def spam(self):
        return self.settings.get("spam")
    @spam.setter
    def spam(self, value):
        return self.settings["spam"] = value

Underlying class SettingsManager is thread safe.
