Set an specific size to a non floating window

[victor-falcon]

I have a second display where I like to keep two windows with this ratio.

RIght now I see myself resizing windows manually, Is there any way to set a shortcut to set this ratio automatically?

the tiling is strictly set to binary partitioning, there are no custom ratios from what I understand.
If you're consistently using specific apps / widows in that configuration you could look at setting a rule so that those apps / winow titles get placed there as floating widnows, but on a specific monitor and in a specific position:

see here: https://github.com/koekeishiya/yabai/wiki/Commands#move-window

I remembered there's the split ratio option: https://github.com/koekeishiya/yabai/wiki/Configuration#split-ratios

But this will apply universally to all screens / spaces, etc. Perhaps it's still of interest

You need to write a script for ratios per monitor

[victor-falcon]

Do you have an example of an script to resize a window until the height eq X?

I have this right now, but now working 😞

#!/bin/bash

TARGET_HEIGHT=910
WINDOW_RESIZE_AMOUNT=10

while [[ $(yabai -m query --windows --window | jq '.frame."h"' | awk '{print int($1)}') -lt $TARGET_HEIGHT ]]; do
	yabai -m window --resize bottom:0:-$WINDOW_RESIZE_AMOUNT
done

For some reason I had to add window_placement last_child to $focus == 2 to make it to work properly, as I have usually set it to first_child, otherwise it applies split ratio only when third window is added... Who knows why. Ideally you need to add windows count, to allow split ratio change only when a second window is created on your display.
Have fun.

.yabairc

yabai -m signal --add event=display_changed action="yabai-per-display"
yabai -m signal --add event=space_changed action="yabai-per-display"

yabai-per-display

#!/bin/zsh
disp=$(yabai -m query --spaces --display)
focus=$(echo $disp | jq '.[0]."index"')

if [[ $focus == "2" ]]; then
	yabai -m config \
	split_type horizontal \
	split_ratio 0.7 \
	window_placement last_child
else
	yabai -m config \
	split_type auto \
	split_ratio 0.5

Finally I went with this script and map it to a shortcut.

#!/bin/bash

TARGET_HEIGHT=890
WINDOW_HEIGHT=$(yabai -m query --windows --window | jq '.frame."h"')
WINDOW_HEIGHT=$(echo $WINDOW_HEIGHT | tr -d '"')
RESIZE_AMOUNT=$(echo "$WINDOW_HEIGHT - $TARGET_HEIGHT" | bc)

if (($(echo "$RESIZE_AMOUNT > 0" | bc -l))); then
	yabai -m window --resize bottom:0:-$RESIZE_AMOUNT
fi
