Match Windows By Classes in hyprland/window

[Patitotective]

Hi, I was wondering if it was possible to rewrite a window's title (in hyprland/window) when a window matches a certain class, instead of a certain title.
This would help a lot when matching kitty windows, which I have configured to show the current command as the title and not "kitty".

{
  ...
  "hyprland/window": {
    ...
    "rewrite": {
       ...
       "(~.*)": "  $1", // Match windows starting with ~
    }
  }
}

Thanks in advance.
Also, just in case if someone knows a way to make these rewrite rules exclusive, i.e.: I want the last defined rule to have priority, instead of all of them working at the same time which looks weird:

{
  ...
  "hyprland/window": {
    ...
    "rewrite": {
       ...
       "(~.*)": "  $1", // Match kitty terminals in the home dir (starting with ~)
       "~": "", // Match empty kitty terminals in the home dir
    }
  }
}

From what I understand, it matches whatever is outputed to the "format" element.

So for me with "format": "{class}", I can just do a rewrite on classes only.

If you have "format": "{title}", you can do rewrites on titles only.

Hi, thanks for your answer.
You seem to be right.
I wish there was a way to rewrite the title based on the class.
