A Ruby String Class that doesn't quote itself when .to_json is called

un_quoted_string.rb

# Represents a string that isn't surrounded by quotes when converted to JSON.
# Originally created to be able to create ruby hashes containing javascript
# function definitions that could be converted to JSON easily.
#
# Use it like this:
# {:number = > 10,
#  :date => Time.now,
#  :regular_string => "Some Quoted Text",
#  :unquoted_string => UnQuotedString("function(){ alert('you can create a function'); }")
# }.to_json
#
# -> {'number':10,
#     'date':'2010-06-14T14:08:36-07:00',
#     'string':'Some Quoted Text',
#     'unquoted_string':function(){ alert('you can create a function'); }}
class UnQuotedString < String
  def to_json(options = nil)
    self
  end
end

# Convenience Factory Method
def UnQuotedString(str)
  UnQuotedString.new(str)
