Window Rules
You can set window rules to achieve different behaviours from the active container.
windowrule=RULE,WINDOW
RULEis a rule (and a param if applicable)WINDOWis a RegEx, either:- plain RegEx (for matching a window class);
title:followed by a regex (for matching a window’s title)
windowrule=float,^(kitty)$
windowrule=move 0 0,title:^(Firefox)(.*)$
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 usehyprctl clients.
| 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. You are also allowed to do 100%- for the right/bottom anchor, e.g. 100%-20) |
| 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 |
| noborder | disables borders for the window |
| noshadow | disables shadows for 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) |
| windowdance | forces an XWayland window to never refocus, used for games/applications like Rhythm Doctor |
| pin | pins the window note: floating only |
| noanim | disables the animations for the window |
windowrule = move 100 100,^(kitty)$
windowrule = animation popin,^(kitty)$
windowrule = noblur,^(firefox)$
Opacity is always a PRODUCT of all opacities. E.g.active_opacityto 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 * 4will cause graphical glitches.
