Instance Method Details

#get_deep ⇒ Object

get_deep digs into a hash along the “route” given by fields elements:

{ foo: { bar: { baz: 1 } } }.get_deep(:foo, :bar, :baz)
# => 1

{ foo: { bar: { baz: 1 } } }.get_deep(:foo, :bar, :baz, :quux)
# => nil

refine Hash do
  def get_deep(*fields)
    fields.inject(self) {|acc,e| acc[e] if acc.is_a?(Hash)}
  end
end

#inits ⇒ Object

inits produces all sub-arrays by successively taking leading elements:

[1, 2, 3].inits
# => [[], [1], [1, 2], [1, 2, 3]]

    (self.length + 1).times.map{ |i| self.take(i) }
  end
end

#tails ⇒ Object

tails produces all sub-arrays by successively dropping leading elements:

[1, 2, 3].tails
# => [[1, 2, 3], [2, 3], [3], []]
