# A Helper for XEP-0118 User Tune
#
# Use this helper to send user tunes, or receive them from a
# specified jid. Described at http://www.xmpp.org/extensions/xep-0118.html
#
# For example:
# <pre>
# h = UserTune::Helper( @client, 'radio1@hug.hellomatty.com' )
# h.add_usertune_callback do |tune|
# puts "Now playing: #{tune.title} by #{tune.artist}"
# end
# </pre>
#
# Also see the examples provided.
class Helper < PubSub::ServiceHelper
##
# Send out the tune currently playing.
#
# track:: [Jabber::UserTune::Tune] the tune currently playing
def now_playing(track)
item = Jabber::PubSub::Item.new()
item.add(track)
publish_item_to(NS_USERTUNE, item)
end
##
# Use this method to indicate that you have stopped playing
# a tune.
def stop_playing
now_playing(Jabber::UserTune::Tune.new())
end
##
# Add a callback that will be invoked when a tune is received
# from the jid specified when you constructed the Helper.
