take over existing windows on startup about bspwm

[baskerville]

I will implement this soon.

[baskerville]

Please try the adopt-orphans branch.

I just tried that branch and bspwm now correctly adopts the orphaned windows. 😺

However, the order of windows (the BSP tree structure) is scrambled every time bspwm re-adopts them.

Is there a way to preserve the order of windows? Thanks.

[sunaku]

For instance, the wmii WM solved this problem by annotating windows with a _WMII_TAGS property. Upon re-adopting orphans, it would read those properties and know how to restore the previous window ordering.

[baskerville]

The window ordering wouldn't be sufficient.

I'm afraid the proper way to do that would be to dump bspwm's current
state (monitors, desktops, nodes) and then read that back on startup.

I found a bug in the current adopt-orphans implementation:

1. Open some windows on the first desktop.
2. Switch to another desktop.
3. Open a terminal.
4. Run bspc quit
5. Relaunch bspwm.
6. Switch back to the first desktop.

Now observe that the first desktop is empty (and all those old windows are gone!). It should not be! 🐛

[baskerville]

6e3af9f should address that.

Thanks, windows from all previous desktops are now adopted into the first (default) one.

Next, could we recreate the previous desktops from the _NET_WM_DESKTOP information?

[baskerville]

The previous desktops will be recreated by the autostart, but what you ask for, I presume, is to put the windows back into their previous respective desktops.

Hopefully, 240c75c will permit that.

But orphan adoption will not occur automatically, you have to add:

bspc adopt_orphans

at the end of your autostart.

The layout can now be restored completely through the restore message.
Please have a look at wm, wm_restart and bspwm_autostart to see how.
