However, it does not tell which workspace is closed. Is there a way to know it? I know a partially useful solution is to always remember the last focused workspace, as in many cases the last focused workspace is new empty workspace. But this is not reliable, since a window can be killed in a workspace that users don't touch.Sat, 06 Dec 2014 07:14:23 +0000https://faq.i3wm.org/question/5106/i3-empty-event-is-there-a-way-to-get-the-workspace-which-is-emptied/https://faq.i3wm.org/question/5106/i3-empty-event-is-there-a-way-to-get-the-workspace-which-is-emptied/?answer=5117#post-id-5117Send a patch to http://cr.i3wm.org/ which modifies i3 to include it. src/con.c:1376 is where the event is generated currently, but you’ll need to switch from a hard-coded string to actually JSON-encoding the workspace title — see the other events. I think a reasonable workaround is to store a list of workspaces, refresh that list of workspaces after getting a “"change": "empty"” workspace event and taking the difference between the two lists.Sat, 06 Dec 2014 22:21:09 +0000https://faq.i3wm.org/question/5106/i3-empty-event-is-there-a-way-to-get-the-workspace-which-is-emptied/?answer=5117#post-id-5117https://faq.i3wm.org/question/5106/i3-empty-event-is-there-a-way-to-get-the-workspace-which-is-emptied/?comment=5122#comment-5122I actually checked the focus event (which gives additional information), but I don't see the JSON way you mentioned...Sat, 06 Dec 2014 22:33:39 +0000https://faq.i3wm.org/question/5106/i3-empty-event-is-there-a-way-to-get-the-workspace-which-is-emptied/?comment=5122#comment-5122
