  @default ||= Hash.new

  name = name.to_s unless name.is_a?(Symbol)
  @default[name] = opts  # ok if this is empty

end

#source(filename, options = {}) ⇒ Object

This is the main point of entry - we call Settings.load! and provide a name of the file to read as it’s argument. We can also pass in some options, but at the moment it’s being used to allow per-environment overrides in Rails

Example Load without environment

> Settings.load!(“config/appdata/example.yml”)

Load with environment

> Settings.load!(

"#{Rails.root}/config/appdata/env-example.yml",
:env => Rails.env)
