Rails - Jan 2007 - text field as date selector (not comboboxes) => how to create customized form helpers?

Having to set 6 comboboxes just to enter a date/time is simply overkill
to me. I prefer a simple text field where I can (e.g. for date input
fields) input strings like
  2007-12-02
  +3  (remark: means the date of 3 days after today)
  12-05  (remark: will be completed with the current year)

I already have implemented the functionality of parsing these dates,
but now I am not sure how to integrate it into the Rails framework
(plugin mechanism?).

Does anybody know how to do this? Is there some documentation about
writing own form helpers like this?

I use this to display and parse european dates (dd.mm.yyyy).

         #to_input_field_tag(''text'',

         options = options.stringify_keys
         options["size"] ||= options["maxlength"] ||

     [match[3].to_i, match[2].to_i, match[1].to_i, nil, nil, nil, nil, nil]
   end
