Carousel

A carousel layout switches between different views based on time or keyboard activity. One use case is an office dashboard with rotating views:

    var blessed = require('blessed')
      , contrib = require('./')
      , screen = blessed.screen()

    function page1(screen) {
       var map = contrib.map()
       screen.append(map)
    }

    function page2(screen) {
      var line = contrib.line(
       { width: 80
       , height: 30
       , left: 15
       , top: 12
       , xPadding: 5
       , label: 'Title'
       })

      var data = [ { title: 'us-east',
                 x: ['t1', 't2', 't3', 't4'],
                 y: [0, 0.0695652173913043, 0.11304347826087, 2],
                 style: {
                  line: 'red'
                 }
               }
            ]

      screen.append(line)
      line.setData(data)
    }

    screen.key(['escape', 'q', 'C-c'], function(ch, key) {
      return process.exit(0);
    });

    var carousel = new contrib.carousel( [page1, page2]
                                       , { screen: screen
                                         , interval: 3000 //how often to switch views (set 0 to never swicth automatically)
                                         , controlKeys: true  //should right and left keyboard arrows control view rotation
                                         })
    carousel.start()
