Using a Ruby Hash Like a Class Object

If you ever need to use a Ruby Hash like a class object, you can achieve this with a simple trick:

class Hashit
  def initialize(hash)
    hash.each do |k,v|
      self.instance_variable_set("@#{k}", v.is_a?(Hash) ? Hashit.new(v) : v)
      self.class.send(:define_method, k, proc { self.instance_variable_get("@#{k}") })
      self.class.send(:define_method, "#{k}=", proc { |v| self.instance_variable_set("@#{k}", v) })
    end
  end
end

h = Hashit.new({a: '123r', b: {c: 'sdvs'}})

# h.a => '123r'
# h.b.c => 'sdvs'

This approach allows you to dynamically create getter and setter methods for hash keys, effectively turning your hash into an object.

Extending Functionality

While this is a basic implementation, you can enhance the Hashit class by adding methods to fit your specific needs.
