This file provides our Redux actions related to local settings. It
consists of the following:
- __`changesLocalSetting(key, value)` :__
Changes the local setting with the given `key` to the given
`value`. `key` **MUST** be an array of strings, as required by
`Immutable.Map.prototype.getIn()`.
- __`saveLocalSettings()` :__
Saves the local settings to `localStorage` as a JSON object. We
shouldn't ever need to call this ourselves.
*/
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
/*
Constants:
----------
We provide the following constants:
- __`LOCAL_SETTING_CHANGE` :__
This string constant is used to dispatch a setting change to our
reducer in `reducers/local_settings`, where the setting is
actually changed.
*/
export const LOCAL_SETTING_CHANGE = 'LOCAL_SETTING_CHANGE';
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
/*
`changeLocalSetting(key, value)`:
---------------------------------
Changes the local setting with the given `key` to the given `value`.
`key` **MUST** be an array of strings, as required by
`Immutable.Map.prototype.getIn()`.
To accomplish this, we just dispatch a `LOCAL_SETTING_CHANGE` to our
reducer in `reducers/local_settings`.

export function changeLocalSetting(key, value) {

dispatch(saveLocalSettings());
};

/*
`saveLocalSettings()`:
----------------------
Saves the local settings to `localStorage` as a JSON object.
`changeLocalSetting()` calls this whenever it changes a setting. We
shouldn't ever need to call this ourselves.
> __TODO :__
> Right now `saveLocalSettings()` doesn't keep track of which user
> is currently signed in, but it might be better to give each user
> their *own* local settings.
