## Window Rules V1

You can set window rules to achieve different behaviours from the active container.

### Syntax

```ini
windowrule=RULE,WINDOW
```

+ `RULE` is a rule (and a param if applicable)
+ `WINDOW` is a RegEx, either:
  + plain RegEx (for matching a window class);
  + `title:` followed by a regex (for matching a window's title)

#### Examples

```ini
windowrule=float,^(kitty)$
windowrule=move 0 0,title:^(Firefox)(.*)$
```

## Window Rules V2

In order to allow more flexible rules, while retaining compatibility with the above
rule system, window rules V2 were implemented.

In V2, you are allowed to match multiple variables.

the `RULE` field is unchanged, but in the `WINDOW` field, you can put regexes for multiple values like so:

```ini
windowrulev2 = float,class:^(kitty)$,title:^(kitty)$
```

For now, the supported fields are:

```ini
class - class regex
title - title regex
xwayland - 0/1
floating - 0/1
```

Keep in mind that you *have* to declare at least one field, but not all.

To get more information about a window's class, title, XWayland status or its size; you can use `hyprctl clients`.

| forceinput                    | forces an XWayland window to receive input, even if it requests not to do so.

### Examples

```ini
windowrule = move 100 100,^(kitty)$
windowrule = animation popin,^(kitty)$
windowrule = noblur,^(firefox)$
```

## Notes

{{< hint type=tip >}}

Opacity is _always_ a PRODUCT of all opacities. E.g. active_opacity to
0.5 and windowrule opacity to 0.5 will result in a total opacity 0.25. You are
allowed to set opacities over 1, but any opacity product over 1 will cause
graphical glitches. E.g. 0.5 _2 = 1, and it will be fine, 0.5_ 4 will cause
graphical glitches.
