How can I get JavaScript style hash access?

Question

I am aware of this feature provided by ActiveSupport.

h = ActiveSupport::OrderedOptions.new
h.boy = \'John\'
h.girl = \'Mary\'
h.boy  # => \'John\'
h.girl # =         


        

Answer 1

OpenStruct should work nicely for this.

If you want to see how it works, or perhaps make a customized version, start with something like this:

h = { 'boy' => 'John', 'girl' => 'Mary' }

class << h
  def method_missing m
    self[m.to_s]
  end
end

puts h.nothing
puts h.boy
puts h.girl
