Window Rules V1

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

Syntax

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

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:

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

For now, the supported fields are:

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.

Rules

Rule	Description
float	floats a window
tile	tiles a window
fullscreen	fullscreens a window
move [x] [y]	moves a floating window (x,y -> int or %, e.g. 20% or 100)
size [x] [y]	resizes a floating window (x,y -> int or %, e.g. 20% or 100)
minsize [x] [y]	sets the minimum size on creation (x,y -> int)
maxsize [x] [y]	sets the maximum size on creation (x,y -> int)
center	if the window is floating, will center it on the monitor
pseudo	pseudotiles a window
monitor [id]	sets the monitor on which a window should open
workspace [w]	sets the workspace on which a window should open (for workspace syntax, see dispatchers->workspaces). You can also make [w] to unset, will unset all previous workspace rules applied to this window. You can also add silent after the workspace to make the window open silently.
opacity [a]	additional opacity multiplier. Options for a: float -> sets an opacity OR float float -> sets activeopacity and inactiveopacity respectively
opaque	forces the window to be opaque (can be toggled with the toggleopaque dispatcher)
animation [style] ([opt])	forces an animation onto a window, with a selected opt. Opt is optional.
rounding [x]	forces the application to have X pixels of rounding, ignoring the set default (in decoration:rounding). Has to be an int.
noblur	disables blur for the window
nofocus	disables focus to the window
forceinput	forces an XWayland window to receive input, even if it requests not to do so. (Might fix issues like e.g. Game Launchers not receiving focus for some reason)
pin	pins the window note: floating only
noanim	disables the animations for the window

Examples

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.
