Class Method Details

.create(hsh) ⇒ Object

Create new storage.

Get hash and try to register each key as method or even sub-storage (it needs for nested hashes). Some keys are not allowed for method registration (f.e. when key = :42). All limitation about Ruby methods naming convention. You can get access to method with any name throw [] thought.

WARNING! Storage is case-sensitive! It means that keys :config and :Config are two different keys!

Sample:

hsh = { cinema: ‘tiger’,

  rate: {3: 'excellent', 2: 'good', 1: 'overage', 0: 'not rated'},
  watched: false,
  'premier' 'soon'
}

s = Storage.new(hsh)

s.cinema # => ‘tiger’ s.rate # => ‘not rated’ s.watched? # => false s # => soon
