A simple Ruby gem adding OpenStruct::parse_json and OpenStruct::parse_hash methods and reverse OpenStruct#to_hash and OpenStruct#to_json methods to (obviously) OpenStruct. It is able to parse and reconstruct nested json and hash objects as well. There is also a OpenStruct#join method adding possibility to replace values in the hash tree with the values passed as a hash in parameter (supporting accepts_nested_attributes_for format) and return it as a new hash.
