How to open GIMP's dialog windows in floating mode?

[danijar]

I would like to have the main window inside the tiled layout and all remaining dialog windows in floating mode. The app name us GIMP-<version> and the main window's title is <filename> (<options>) <dimensions> – GIMP.

I first tried to use a negative lookahead. However, I found that yabai does not support negative lookaheads.

yabai -m rule --add app='^GIMP' title='(?!GIMP)$' manage=off

I then to use the negative syntax explained in this issue. However, this gives an unknown key 'title[!]' error in yabai v3.3.0.

yabai -m rule --add app='^GIMP' 'title[!]="GIMP$"' manage=off

How can I write a rule that disables the tiling window management for GIMP windows except for the main window?

[] means optional, so you should use title=xxx or title!=xxx.

As yanzhang mentioned, yabai -m rule --add app='^GIMP' title!='GIMP$' manage=off should do it.

Perfect, thanks! I had to catch one more special case where the main window title would be different when no image is loaded. The complete rule is:

yabai -m rule --add app='^GIMP' title!='(^GNU|GIMP$)' manage=off

I needed a $ at the end of the app name:
yabai -m rule --add app='^GIMP$' title!='(^GNU|GIMP$)' manage=off
