require 'json' ## # The JsonIndex generator is designed to complement an HTML generator and # produces a JSON search index. This generator is derived from sdoc by # Vladimir Kolesnikov and contains verbatim code written by him. # # This generator is designed to be used with a regular HTML generator: # # class RDoc::Generator::Darkfish # def initialize options # # ... # @base_dir = Pathname.pwd.expand_path # # @json_index = RDoc::Generator::JsonIndex.new self, options # end # # def generate # # ... # @json_index.generate # end # end # # == Index Format # # The index is output as a JSON file assigned to the global variable # +search_data+. The structure is: # # var search_data = { # "index": { # "searchIndex": # ["a", "b", ...], # "longSearchIndex": # ["a", "a::b", ...], # "info": [ # ["A", "A", "A.html", "", ""], # ["B", "A::B", "A::B.html", "", ""], # ... # ] # } # } # # The same item is described across the +searchIndex+, +longSearchIndex+ and # +info+ fields. The +searchIndex+ field contains the item's short name, the # +longSearchIndex+ field contains the full_name (when appropriate) and the # +info+ field contains the item's name, full_name, path, parameters and a # snippet of the item's comment. # # == LICENSE # # Copyright (c) 2009 Vladimir Kolesnikov # # Permission is hereby granted, free of charge, to any person obtaining # a copy of this software and associated documentation files (the # "Software"), to deal in the Software without restriction, including # without limitation the rights to use, copy, modify, merge, publish, # distribute, sublicense, and/or sell copies of the Software, and to # permit persons to whom the Software is furnished to do so, subject to # the following conditions: # # The above copyright notice and this permission notice shall be # included in all copies or substantial portions of the Software. # # THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, # EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF # MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND # NONINFRINGEMENT.
