[flip111]

config

    new \Phergie\Irc\Plugin\React\FeedTicker\Plugin([

      // required: list of feed URLs to poll for content
      'urls' => [
          'https://groups.google.com/forum/feed/elm-discuss/msgs/atom.xml?num=50',
          'https://github.com/elm-lang/core/commits/master.atom',
          'https://github.com/symfony/symfony/commits/master.atom'
      ],

      // required: lists of channels or users to receive syndicated feed items
      //           keyed by associated connection mask
      'targets' => [
        '[email protected]' => [
          '#elm-bot'
        ]
      ],
      'interval' => 300,

      // optional: object implementing \Phergie\Irc\Plugin\React\FeedTicker\FormatterInterface
      //           used to format data from feed items prior to their syndication
      'formatter' => new Phergie\Irc\Plugin\React\FeedTicker\DefaultFormatter(
          '%title% [ %link% ] by %authorname% at %datemodified%',
          'Y-m-d H:i:s'
      ),
    ])
