7	Window Rules

{{< callout type=warning >}}

Window rules (both V1 and V2) are case sensitive. (e.g. firefox ≠ Firefox)

{{< /callout >}}

Window Rules V1

You can set window rules to achieve different behaviors 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)

{{< callout type=info >}}

In the case of dynamic window titles such as browser windows, keep in mind how powerful regex is.

For example, a window rule of: windowrule=opacity 0.3 override 0.3 override,title:(.*)(- Youtube)$ will match any window that contains a string of "- Youtube" after any other text. This could be multiple browser windows or other applications that contain the string for any reason.

For the windowrulev2 = float,class:(kitty),title:(kitty) example, the class:(kitty) WINDOW field is what keeps the window rule specific to kitty terminals.

{{< /callout >}}

For now, the supported fields for V2 are:

class - class regex 
title - title regex
initialclass - initialClass regex
initialTitle - initialTitle regex
xwayland - 0/1
floating - 0/1
fullscreen - 0/1
pinned - 0/1
focus - 0/1
workspace - id or name: and name
onworkspace - id, name: and name, or workspace selector (see Workspace Rules)

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

{{< callout type=info >}}

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

{{< /callout >}}

{{< callout type=warning >}}

Please beware that hyprctl clients will display the field as initialClass while the WINDOW field in the configuration uses initialclass.

Rules

Static rules

Static rules are evaluated once when the window is opened and never again.

Rule	Description
float	floats a window
tile	tiles a window
fullscreen	fullscreens a window
fakefullscreen	fakefullscreens a window
maximize	maximizes 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. In addition, the option supports the subtraction of the window size with 100%-w-, e.g. 100%-w-20. This results in a gap at the right/bottom edge of the screen to the window with the defined subtracted size). Additionally, you can also do cursor [x] [y] where x and y are either pixels or percent. Percent is calculated from the window's size. Specify onscreen before other parameters to force the window into the screen (e.g. move onscreen cursor 50% 50%)
size [x] [y]	resizes a floating window (x,y -> int or %, e.g. 20% or 100)
center ([opt])	if the window is floating, will center it on the monitor. Set opt as 1 to respect monitor reserved area
pseudo	pseudotiles a window
monitor [id]	sets the monitor on which a window should open. id can be either id or name (either e.g. 1 or e.g. DP-1)
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.
nofocus	disables focus to the window
noinitialfocus	disables the initial 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)
windowdance	forces an XWayland window to never refocus, used for games/applications like Rhythm Doctor
pin	pins the window (i.e. show it on all workspaces) note: floating only
unset	removes all previously set rules for the given parameters. Please note it has to match EXACTLY.
nomaxsize	removes max size limitations. Especially useful with windows that report invalid max sizes (e.g. winecfg)
stayfocused	forces focus on the window as long as it's visible
group [options]	set window group properties. See the note below.
suppressevent [types...]	ignores specific events from the window. Events are space separated, and can be: fullscreen maximize activate activatefocus

Dynamic rules

Dynamic rules are re-evaluated every time a property changes.

Rule	Description
opacity [a]	additional opacity multiplier. Options for a: float -> sets an overall opacity OR float float -> sets activeopacity and inactiveopacity respectively, OR float float float -> sets activeopacity, inactiveopacity and fullscreenopacity respectively.
opaque	forces the window to be opaque (can be toggled with the toggleopaque dispatcher)
forcergbx	makes Hyprland ignore the alpha channel of all the window's surfaces, effectively making it actually, fully 100% opaque
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.
minsize [x] [y]	sets the minimum size (x,y -> int)
maxsize [x] [y]	sets the maximum size (x,y -> int)
noblur	disables blur for the window
noborder	disables borders for the window
bordersize [size]	sets the border size
nodim	disables window dimming for the window
noshadow	disables shadows for the window
noanim	disables the animations for the window
keepaspectratio	forces aspect ratio when resizing window with the mouse
bordercolor [c]	force the bordercolor of the window. Options for c: color/color ... color angle -> sets the active border color/gradient OR color color/color ... color angle color ... color [angle] -> sets the active and inactive border color/gradient of the window. See variables->colors for color definition.
idleinhibit [mode]	sets an idle inhibit rule for the window. If active, apps like hypridle will not fire. Modes: none, always, focus, fullscreen
dimaround	dims everything around the window . Please note this rule is meant for floating windows and using it on tiled ones may result in strange behavior.
xray [on]	sets blur xray mode for the window (0 for off, 1 for on, unset for default)
immediate	forces the window to allow to be torn. See the Tearing page.
nearestneighbor	forces the window to use the nearest neigbor filtering.

group window rule options

• set [always] - Open window as a group.
• new - Shorthand of barred set.
• lock [always] - Lock the group that added this window. Use with set or new (i.e. new lock) to create a new locked group.
• barred - Do not add the window to the focused group. By default, a window with a group set rule will be added to an active group if possible.
• deny - Do not allow window to be toggled as or added to group (see denywindowfromgroup dispatcher).
• invade - Force open window in the locked group.
• override [other options] - Override other group rules, e.g. You can make all windows in a particular workspace open as a group, and use group override barred to make windows with specific titles open as normal windows.
• unset - Clear all group rules.

The group rule without options is a shorthand for group set.

By default, set and lock only affect new windows once. The always qualifier makes them always effective.

Example Rules

windowrule = move 100 100,^(kitty)$ # moves kitty to 100 100
windowrule = animation popin,^(kitty)$ # sets the animation style for kitty
windowrule = noblur,^(firefox)$ # disables blur for firefox
windowrule = move cursor -50% -50%,^(kitty)$ # moves kitty to the center of the cursor
windowrulev2 = bordercolor rgb(FF0000) rgb(880808),fullscreen:1 # set bordercolor to red if window is fullscreen
windowrulev2 = bordercolor rgb(FFFF00),title:^(.*Hyprland.*)$ # set bordercolor to yellow when title contains Hyprland
windowrule = opacity 1.0 override 0.5 override 0.8 override,^(kitty)$ # set opacity to 1.0 active, 0.5 inactive and 0.8 fullscreen for kitty
windowrule = rounding 10,^(kitty)$ # set rounding to 10 for kitty
windowrulev2 = stayfocused, class:^(pinentry-) # fix pinentry losing focus

Notes

Rules that are marked as Dynamic will be reevaluated if the matching property of the window changes. For instance, if a rule is defined that changes the bordercolor of a window when it is floating, then the bordercolor will change to the requested color when it is set to floating, and revert to the default color when it is tiled again.

Rules will be processed from top to bottom, where the last match will take precedence. i.e.

windowrulev2 = opacity 0.8 0.8,class:^(kitty)$
windowrulev2 = opacity 0.5 0.5,floating:1

Here, all non-fullscreen kitty windows will have opacity 0.8, except if they are floating. Otherwise, they will have opacity 0.5. The rest of the non-fullscreen floating windows will have opacity 0.5.

windowrulev2 = opacity 0.5 0.5,floating:1
windowrulev2 = opacity 0.8 0.8,class:^(kitty)$

Here, all kitty windows will have opacity 0.8, even if they are floating. The rest of the floating windows will have opacity 0.5.

{{< callout type=info >}}

Opacity is a PRODUCT of all opacities by default. For example, setting activeopacity to 0.5 and opacity to 0.5 will result in a total opacity of 0.25. You are allowed to set opacities over 1, but any opacity product over 1 will cause graphical glitches. For example, using 0.5 * 2 = 1 is fine, but 0.5 * 4 = 2 will cause graphical glitches. You can put override after an opacity value to override it to an exact value rather than a multiplier. For example, to set active and inactive opacity to 0.8, and make fullscreen windows fully opaque regardless of other opacity rules:

windowrulev2 = opacity 0.8 override 0.8 override 1.0 override,^(kitty)$

Layer Rules

Some things in Wayland are not windows, but layers. That includes, for example: app launchers, status bars, or wallpapers.

Those have specific rules separate from windows:

layerrule = rule, namespace
# or
layerrule = rule, address

where rule is the rule and namespace is the namespace regex (find namespaces in hyprctl layers) or address is an address in the form of address:0x[hex]

Rules

rule	description
unset	removes all layerRules previously set for a select namespace regex. Please note it has to match exactly.
noanim	disables animations
blur	enables blur for the layer
blurpopups	enables blur for the popups
ignorealpha [a]	makes blur ignore pixels with opacity of a or lower. a is float value from 0 to 1. a = 0 if unspecified.
ignorezero	makes blur ignore fully transparent pixels. Same as ignorealpha 0.
dimaround	dims everything behind the layer
xray [on]	sets the blur xray mode for a layer. 0 for off, 1 for on, unset for default.
animation [style]	allows you to set a specific animation style for this layer
