Window Rules

Note

Looking for the old hyprlang syntax? Check the 0.54 wiki pages. Since Hyprland 0.55, hyprlang is deprecated in favor of lua.

Warning

Rules are evaluated top to bottom, so the order they’re written in does matter! More info in Notes

Window Rules

You can set window rules to achieve different window behaviors based on their properties.

Syntax

Basic named rule syntax:

hl.window_rule({
  name = "apply-something",
  match = {
    class = "my-window"
  },
  border_size = 10
})

Basic anonymous rule syntax:

hl.window_rule({ match = { class = "my-window" }, border_size = 10 })

Rules are split into two categories of parameters: props and effects. Props are the fields inside the match table, which are used to determine if a window should get the rule. Effects are what is applied.

All props must match for a rule to be applied.

You can have as many props and effects per rule as you please, in any order as you please, as long as:

there is only one of one type (e.g. specifying match.class twice is invalid)
there is at least one prop

Props

The supported fields for the match table are:

Field	Argument	Description
class	[RegEx]	Windows with `class` matching `RegEx`.
title	[RegEx]	Windows with `title` matching `RegEx`.
initial_class	[RegEx]	Windows with `initialClass` matching `RegEx`.
initial_title	[RegEx]	Windows with `initialTitle` matching `RegEx`.
tag	[name]	Windows with matching `tag`.
xwayland	[bool]	Xwayland windows.
float	[bool]	Floating windows.
fullscreen	[bool]	Fullscreen windows.
pin	[bool]	Pinned windows.
focus	[bool]	Currently focused window.
group	[bool]	Grouped windows.
modal	[bool]	Modal windows (e.g. “Are you sure” popups)
fullscreen_state_client	[int]	Windows with matching `fullscreenstate`. `0` - none, `1` - maximize, `2` - fullscreen, `3` - maximize and fullscreen.
fullscreen_state_internal	[int]	Windows with matching `fullscreenstate`. `0` - none, `1` - maximize, `2` - fullscreen, `3` - maximize and fullscreen.
workspace	[workspace]	Windows on matching workspace. Can be `id`, `"name:string"` or a workspace selector.
content	[string]	Windows with specified content type (none, photo, video, game).
xdg_tag	[RegEx]	Match a window by its xdgTag (see `hyprctl clients` to check if it has one).

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

Note

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

Note

In the output of the hyprctl clients command: fullscreen refers to fullscreen_state_internal and fullscreenClient refers to fullscreen_state_client

RegEx writing

Please note Hyprland uses Google’s RE2 for parsing RegEx. This means that all operations requiring polynomial time to compute will not work. See the RE2 wiki for supported extensions.

If you want to negate a RegEx, as in pass only when the RegEx fails, you can prefix it with negative:, e.g.: "negative:kitty".

Effects

Static effects

Static effects are evaluated once when the window is opened and never again. This essentially means that it is always the initialTitle and initialClass which will be found when matching on title and class, respectively.

Warning

It is not possible to float (or any other static rule) a window based on a change in the title after the window has been created. This applies to all static effects listed here.

Effect	Argument	Description
float	boolean	Floats a window.
tile	boolean	Tiles a window.
fullscreen	boolean	Fullscreens a window.
maximize	boolean	Maximizes a window.
fullscreen_state	string	Sets the fullscreen mode, e.g. `"1 2"` (internal client). Values: `0` none, `1` maximize, `2` fullscreen, `3` maximize and fullscreen.
move	string	Moves a floating window to a given coordinate, monitor-local. E.g. `"100 200"` or `"(cursor_x-(window_w0.5)) (cursor_y-(window_h0.5))"`.
size	string	Resizes a floating window. E.g. `"800 600"` or `"(monitor_w0.5) (monitor_h0.5)"`.
center	boolean	If the window is floating, will center it on the monitor.
pseudo	boolean	Pseudotiles a window.
monitor	string	Sets the monitor on which a window should open. E.g. `"1"` or `"DP-1"`.
workspace	string	Sets the workspace on which a window should open. Can also be `"unset"` or suffixed with `" silent"`.
no_initial_focus	boolean	Disables the initial focus to the window.
pin	boolean	Pins the window (i.e. show it on all workspaces). Note: floating only.
group	string	Sets window group properties. See group options below.
suppress_event	string	Ignores specific events. Space-separated: `"fullscreen"`, `"maximize"`, `"activate"`, `"activatefocus"`, `"fullscreenoutput"`.
content	string	Sets content type: `"none"`, `"photo"`, `"video"`, or `"game"`.
no_close_for	integer	Makes the window uncloseable with `killactive` for a given number of ms on open.
scrolling_width	number	Set column width for window when starting on a workspace with the scrolling layout.

Expressions

Expressions are used with move and size. They are space-separated (no spaces within each expression). All position variables are monitor-local.

monitor_w and monitor_h for monitor size
window_x and window_y for window position
window_w and window_h for window size
cursor_x and cursor_y for cursor position

Example expressions:

move = "window_w*0.5 (monitor_h/2)+17"
size = "(monitor_w*0.5) (monitor_h*0.5)"

Dynamic effects

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

Effect	Argument	Description
persistent_size	boolean	For floating windows, internally store their size. When a new floating window opens with the same class and title, restore the saved size.
no_max_size	boolean	Removes max size limitations.
stay_focused	boolean	Forces focus on the window as long as it’s visible.
animation	string	Forces an animation onto a window with an optional style. E.g. `"popin"` or `"popin 80%"`.
border_color	gradient	Force the border color. Accepts a color, gradient, or two gradients (active/inactive). E.g. `"rgb(FF0000)"` or `{ colors = {"rgba(33ccffee)", "rgba(00ff99ee)"}, angle = 45 }`.
idle_inhibit	string	Sets an idle inhibit rule. Modes: `"none"`, `"always"`, `"focus"`, `"fullscreen"`.
opacity	string	Additional opacity multiplier. E.g. `"0.8"` (overall), `"0.9 0.7"` (active/inactive), `"1.0 0.8 0.9"` (active/inactive/fullscreen). Append `" override"` after each value to set absolute instead of multiplied.
tag	string	Applies a tag. Use prefix `+`/`-` to set/unset, or no prefix to toggle. E.g. `"+myTag"`.
max_size	vec2	Sets the maximum size for floating windows. E.g. `{ 800, 600 }`.
min_size	vec2	Sets the minimum size for floating windows. E.g. `{ 200, 150 }`.
border_size	integer	Sets the border size.
rounding	integer	Forces X pixels of rounding, ignoring the default.
rounding_power	number	Overrides the rounding power for the window.
allows_input	boolean	Forces an XWayland window to receive input even if it requests not to.
dim_around	boolean	Dims everything around the window. Meant for floating windows.
decorate	boolean	Whether to draw window decorations. (default: `true`)
focus_on_activate	boolean	Whether Hyprland should focus an app that requests to be focused.
keep_aspect_ratio	boolean	Forces aspect ratio when resizing with the mouse.
nearest_neighbor	boolean	Forces nearest-neighbor filtering.
no_anim	boolean	Disables animations for the window.
no_blur	boolean	Disables blur for the window.
no_dim	boolean	Disables window dimming for the window.

no_shortcuts_inhibit	boolean	Disallows the app from inhibiting your shortcuts.
no_screen_share	boolean	Hides the window and its popups from screen sharing by drawing black rectangles in their place.
no_vrr	boolean	Disables VRR for the window. Only works when `misc.vrr` is set to `2` or `3`.
opaque	boolean	Forces the window to be opaque.
force_rgbx	boolean	Forces Hyprland to ignore the alpha channel entirely.
sync_fullscreen	boolean	Whether the fullscreen mode should always be the same as the one sent to the window.
immediate	boolean	Forces the window to allow tearing.
xray	boolean	Sets blur xray mode for the window.
render_unfocused	boolean	Forces the window to think it’s being rendered when it’s not visible.
scroll_mouse	number	Forces the window to override `input.scroll_factor`.
scroll_touchpad	number	Forces the window to override `input.touchpad.scroll_factor`.

All dynamic effects can be set with setprop.

`group` window rule options

The group effect takes a string with space-separated options:

"set" ["always"] - Open window as a group.
"new" - Shorthand for "barred set".
"lock" ["always"] - Lock the group. Combine with "set" or "new".
"barred" - Do not automatically group into the focused unlocked group.
"deny" - Do not allow the window to be toggled as or added to a group.
"invade" - Force open window in the locked group.
"override" [other options] - Override other group rules.
"unset" - Clear all group rules.

Note

group with no 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

-- Move kitty to 100 100 and add an anim style (named rule)
hl.window_rule({
  name      = "move-kitty",
  match     = { class = "kitty" },
  move      = "100 100",
  animation = "popin",
})

-- Disable blur for firefox
hl.window_rule({ match = { class = "firefox" }, no_blur = true })

-- Move kitty to the center of the cursor
hl.window_rule({
  match = { class = "kitty" },
  move  = "(cursor_x-(window_w*0.5)) (cursor_y-(window_h*0.5))",
})

-- Set border color to red if window is fullscreen
hl.window_rule({
  match        = { fullscreen = true },
  border_color = "rgb(FF0000) rgb(880808)",
})

-- Set border color to yellow when title contains Hyprland
hl.window_rule({
  match        = { title = ".*Hyprland.*" },
  border_color = "rgb(FFFF00)",
})

-- Set opacity to 1.0 active, 0.5 inactive and 0.8 fullscreen for kitty
hl.window_rule({
  match   = { class = "kitty" },
  opacity = "1.0 override 0.5 override 0.8 override",
})

-- Set rounding to 10 for kitty
hl.window_rule({ match = { class = "kitty" }, rounding = 10 })

-- Fix pinentry losing focus
hl.window_rule({
  match       = { class = "(pinentry-)(.*)" },
  stay_focused = true,
})

Notes

Effects marked as Dynamic are reevaluated whenever the matching property of the window changes. For instance, if a rule changes the border_color when a window is floating, the color reverts to default when it’s tiled again.

Effects are processed top to bottom - the last match takes precedence:

hl.window_rule({ match = { class = "kitty" },        opacity = "0.8 0.8" })
hl.window_rule({ match = { float = true },           opacity = "0.5 0.5" })

Here, all non-fullscreen kitty windows have opacity 0.8, except when floating - those get 0.5. All other floating windows get 0.5.

hl.window_rule({ match = { float = true },           opacity = "0.5 0.5" })
hl.window_rule({ match = { class = "kitty" },        opacity = "0.8 0.8" })

Here, all kitty windows get opacity 0.8, even if floating. Other floating windows get 0.5.

Important

Named rules take precedence over anonymous ones. Rules are evaluated top to bottom, but all named rules are evaluated first, then all anonymous ones.

Note

Opacity is a PRODUCT of all opacities by default. For example, setting active_opacity to 0.5 and opacity to 0.5 results in a total of 0.25. Opacities over 1.0 are allowed, but any product over 1.0 will cause graphical glitches.

Use " override" after an opacity value to set it as an exact value rather than a multiplier:

-- Active 0.8, inactive 0.8, fullscreen 1.0 regardless of other rules:
hl.window_rule({
  match   = { class = "kitty" },
  opacity = "0.8 override 0.8 override 1.0 override",
})

Dynamically enabling / disabling / changing rules

Only named rules can be dynamically changed, enabled, or disabled. hl.window_rule() returns a handle object:

local myRule = hl.window_rule({
  name  = "my-rule",
  match = { class = "kitty" },
  border_size = 5,
})

myRule:set_enabled(false)  -- disable
myRule:set_enabled(true)   -- re-enable
myRule:is_enabled()        -- query status

Layer Rules

Some things in Wayland are not windows, but layers - app launchers, status bars, wallpapers, etc. These have separate rules using hl.layer_rule(). The syntax is the same as hl.window_rule().

Props

Field	Argument	Description
namespace	[RegEx]	Namespace of the layer. Check `hyprctl layers`.

Effects

Effect	Argument	Description
no_anim	boolean	Disables animations.
blur	boolean	Enables blur for the layer.
blur_popups	boolean	Enables blur for popups.
ignore_alpha	number	Makes blur ignore pixels with opacity of `a` or lower. Float from `0` to `1`.
dim_around	boolean	Dims everything behind the layer.
xray	boolean	Sets the blur xray mode for the layer.
animation	string	Sets a specific animation style for this layer.
order	integer	Sets the order relative to other layers. Higher `n` = closer to edge of monitor. Can be negative.
above_lock	integer	If non-zero, renders the layer above the lockscreen. `2` = interactive on lockscreen.
no_screen_share	boolean	Hides the layer from screen sharing.

Examples

-- Enable blur for waybar
hl.layer_rule({ match = { namespace = "waybar" }, blur = true })

-- Named layer rule
local selectionRule = hl.layer_rule({
  name      = "no-anim-for-selection",
  match     = { namespace = "selection" },
  no_anim   = true,
})

-- Enable blur and ignore_alpha for rofi
hl.layer_rule({
  match        = { namespace = "rofi" },
  blur         = true,
  ignore_alpha = 0.5,
})

Layer rules also return a handle with set_enabled() / is_enabled():

local myLayerRule = hl.layer_rule({
  name  = "my-layer-rule",
  match = { namespace = "waybar" },
  blur  = true,
})
myLayerRule:set_enabled(false)
