introduced i3 command for changing the hidden state and the mode of i3bar The hidden_state and mode of each i3bar instance can now be controlled from within i3. Therefore, two new i3 command were introduced: _ bar hidden_state show|hide|toggle [<bar_id>] show: always show the bar hide: normal hide mode toggle: toggle between show and hide (individually for each bar) _ bar mode dock|hide|invisible|toggle [<bar_id>] hide,dock: like before invisible: always keep the bar hidden toggle: toggle between dock and hide (individually for each bar) This patch introduces a hidden_state ("hidden_state hide|show") in the barconfig, which indicates the current hidden_state of each i3bar instance. It only affects the bar when in hide mode. Additionally, a new invisible mode was introduced. In order to change the hidden_state or mode of the bar from i3, a barconfig-update event was introduced, for which a bar can subscribe and the bar then gets notified about the currently set hidden_state and mode in its barconfig. For convenience, an id field ("id <bar_id>") was added to the barconfig, where one can set the desired id for the corresponding bar. If the id is not specified, i3 will deterministically choose an id; otherwise, with the previous random approach for finding a new id, which is actually not shared with i3bar, as it would determine its id on startup, the event-subscription would be destroyed on reload. Still, this issue remains when manually changing the bar_id in the config and then reloading. fixes #833, #651
