Supporting another version of the dsl (backward compatible)

[guilhermesilveira]

In this patch, there is another version of the dsl that is backward compatible and gives less noise on the dsl. This approach is Ruby 1.8.7+ compatible. Both json and xml have been changed to support it (applying changes to the builder base). Usage example:

xml = Tokamak::Builder::Xml.build(some_articles) do
    write :id,      "http://example.com/json"
    title   "Feed"
    updated time

    author {
      name  "John Doe"
      email "joedoe@example.com"
    }

    author {
      name  "Foo Bar"
      email "foobar@example.com"
    }

  link("next"    , "http://a.link.com/next")
  link("previous", "http://a.link.com/previous")

  members(:root => "articles") do |member, article|
      write :id,      "uri:#{article[:id]}"
      title   article[:title]
      updated article[:updated]

    link("image", "http://example.com/image/1")
    link("image", "http://example.com/image/2", :type => "application/json")
  end
end

In 1.9.2 the method id has been dropped so it is even simpler.

there is a reason to not implement this: the []= method for adding namespaces to xml output would be impossible to be executed.

closing due to reason posted above and no discussion followed

[guilhermesilveira]

just uploaded the method ns for namespace declaration. branch dsl it also includes the full dsl support discussed on the mailing list
