Module: AppConfig

Included in:
Dvdprofiler2xbmc::CLI
Defined in:
lib/dvdprofiler2xbmc/app_config.rb

Overview

Synopsis

This module encapsulates the application’s config hash by adding default, load, and save methods. Also behaves as a global hash, meaning you can access it from anywhere in your code like:

AppConfig[:images_dir]

or

AppConfig['images_dir']

Note this is because the implementation is a Mash instead of a Hash and does cause a limitation where the key must be either a symbol or a string.
