  function() -- changes Textadept title to show 'clean' buffer

    set_title(buffer)
  end)

events.connect('save_point_left',
  function() -- changes Textadept title to show 'dirty' buffer
    buffer.dirty = true
    set_title(buffer)
  end)

events.connect('buffer_after_switch',
  function() -- updates titlebar and statusbar
    set_title(buffer)
    events.emit('update_ui')
  end)

events.connect('view_after_switch',
  function() -- updates titlebar and statusbar
    set_title(buffer)
    events.emit('update_ui')
