# DEPRECATED. Just write the logic into a custom Decorator yourself.
# See wiki on decorators.
#
#
# Example of an Item Decorator that ADDs an 'other link' with an openurl.
#
# This example uses crazy metaprogramming to dynamically create
# a module configured with your base url etc. You don't need to use
# crazy method like that; just define your own local decorator doing
# exactly what you need, it's meant to be simple.
#
# config.item_decorators = [ BentoSearch::OpenurlAddOtherLink[:base_url => "http://resolve.somewhere.edu/foo", :extra_query => "&foo=bar"] ]
#
module BentoSearch::OpenurlAddOtherLink
def self.[](options)
base_url = options[:base_url]
extra_query = options[:extra_query] || ""
link_name = options[:link_name] || "Find It"
# overwrite: if true, overwrite previously existing other_links, if
# false add on to previously existing.
overwrite = options.has_key?(:overwrite) ? options[:overwrite] : false
Module.new do
define_method :other_links do
start = overwrite ? [] : super()
if (ou = to_openurl)
start + [BentoSearch::Link.new(:url => "#{base_url}?#{ou.kev}#{extra_query}", :label => link_name)]
