Subject: Re: Creating instance variables while looping over a hash

Just an example to explain my mind :

---
# some representation of your data
config = {'config' => {'value1' => 'Something here', 'value2' =>
'Something else'}}

class A
  def m config
    config["config"].each { |key, value| 
      # attr_accessor key (optional)
      self.class.instance_eval {attr_accessor key.to_s}
      # @key = value
      instance_variable_set "@#{key}", value
    }
  end
end

# test
a = A.new
a.m config
p a.value2
---

you can also specify if you want an attribute readable and/or writable
