##Dependencies nokogiri

htmlentities

Add it to dashing's gemfile:

gem 'nokogiri'
gem 'htmlentities'

and run bundle install.

##Usage To use this widget, copy news.html, news.coffee, and news.scss into the /widgets/news directory. Put the news.rb file in your /jobs folder.

To include the widget in a dashboard, add the following snippet to the dashboard layout file:

<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="seattle-times" data-view="News" data-title="Seattle Times" data-interval="30"></div>
</li>

At the top of the news.rb job file, add any rss feed urls you want fetched to the hash, and the widget id to send data to. In the dashboard layout file, the optional data-interval binding can be used to specify how frequently to rotate the news items.

rss.coffee

class Dashing.Rss extends Dashing.Widget

  ready: ->
    @currentIndex = 0
    @headlineElem = $(@node).find('.headline-container')
    @nextComment()
    @startCarousel()

  onData: (data) ->
    @currentIndex = 0

  startCarousel: ->
    interval = $(@node).attr('data-interval')
    interval = "30" if not interval
    setInterval(@nextComment, parseInt( interval ) * 1000)

  nextComment: =>
    headlines = @get('headlines')
    if headlines
      @headlineElem.fadeOut =>
        @currentIndex = (@currentIndex + 1) % headlines.length
        @set 'current_headline', headlines[@currentIndex]
        @headlineElem.fadeIn()
