Get master window using hyprctl?

[akiross]

I was interested in a feature like the one in issue #1265, so I was wondering whether it's possible to automate that using hyprctl, but to do that, I would need to get the id of the master window.

Is there a way to get the master window using hyprctl?

You can do a surprising amount with hyprctl -j and jq, for example, you can write something like this:

hyprctl clients -j | jq "[.[] | select (.workspace.id == $(hyprctl activewindow -j | jq .workspace.id))] | min_by(.at[0]) | .address"

You might have to do some more filtering to handle floating/pseudotiled windows, or change the min_by(.at[0]) to fit your master position (max_by will return the rightmost, and [1] will return a y-position), or some porting if you aren't using fish, but this should be a decent jumping off point.
