@param [String/Fixnum] target to listen on (hostname:port or port)

@yield [modified, added, removed] the changed files @yieldparam [Array<String>] modified the list of modified files @yieldparam [Array<String>] added the list of added files @yieldparam [Array<String>] removed the list of removed files

@return [Listen::Listener] the listener

# File lib/listen.rb, line 55
def on(target, *args, &block)
