Yabai: [Question] Help with un-managing Firefox Nightly update window with no title

[muhammad-saleh]

Hi,
Thank you for creating Yabai and thank you for your great efforts.

I need your help please with un-managing the Firefox Nightly update window, it has no title.

I have this rule in my yabairc file but it doesn't work, Could someone please tell me what do I need to change to get the update window to float?

This window is what's shown when you check for updates in Firefox Nightly.

Thank you 🙏

yabai -m rule --add app="^Firefox*" title="" manage=off

Open this update window and a terminal in the same workspace. Then try to run yabai -m query --windows --space in the terminal. You can get the information about both windows in the current workspace. Then you could find the actual name and title of this firefox update window.

@yanzhang0219 That's what I got for this window:

{
    "id":665,
    "pid":3296,
    "app":"Firefox Nightly",
    "title":"",
    "frame":{
        "x":753.0000,
        "y":28.0000,
        "w":654.0000,
        "h":365.0000
    },
    "level":0,
    "role":"AXWindow",
    "subrole":"AXStandardWindow",
    "movable":1,
    "resizable":0,
    "display":1,
    "space":1,
    "visible":1,
    "focused":0,
    "split":"vertical",
    "floating":0,
    "sticky":0,
    "minimized":0,
    "topmost":0,
    "opacity":1.0000,
    "shadow":1,
    "border":0,
    "zoom-parent":0,
    "zoom-fullscreen":0,
    "native-fullscreen":0
},

Try this yabai rule yabai -m rule --add app="Firefox Nightly" title="" manage=off to see whether it works?

[muhammad-saleh]

@yanzhang0219 It didn't work unfortunately! Is there a way to validate that this rule is loaded?

[yanzhang0219]

yabai -m rule --list will list all registered rules.

[muhammad-saleh]

@yanzhang0219 interesting... if the rule has title="" it's not loaded and if I removed the title from the rule, the rule will be loaded but this will make the whole app float

[muhammad-saleh]

Maybe there should be a unique value/identifier for either managing/un-managing all app windows or a unique identifier for empty titles, something like title="[EMPTY]"

[dominiklohmann]

You gotta use title='^$' for the empty title. The empty string matches _every_ title, but ^$ matches only entirely empty titles (^ refers to the start of the line, $ refers to the end of the line).

@dominiklohmann Works! Thank you both a lot!

[yanzhang0219]

Wow. Interesting! I don't know this before. Thank you @dominiklohmann
