# NAME
sway - configuration file and commands
# DESCRIPTION
A sway configuration file is a list of sway commands that are executed by sway
on startup. These commands usually consist of setting your preferences and
setting key bindings. An example config is likely present in /etc/sway/config
for you to check out.
Lines in the configuration file might be extended through multiple lines by
adding a '\\' character at the end of line. e.g.:
```
bindsym Shift+XF86AudioRaiseVolume exec \\
pactl set-sink-volume @DEFAULT_SINK@ -1%
```
Commands can also be given as a block in the form *command { <subcommands...>
}*. Anything before the opening *{* will be prepended to the lines inside the
block. For example:
```
output eDP-1 {
background ~/wallpaper.png
resolution 1920x1080
}
```
is identical to
```
output eDP-1 background ~/wallpaper.png
output eDP-1 resolution 1920x1080
```
These commands can be executed in your config file, via *swaymsg*(1), or via
the bindsym command.
# COMMAND CONVENTIONS
Commands are split into several arguments using spaces. You can enclose
arguments with quotation marks (*"..."* or *'...'*) to add spaces to a single
argument. You may also run several commands in order by separating each with
*,* or *;*.
Throughout the documentation, *|* is used to distinguish between arguments for
which you may only select one. *[...]* is used for optional arguments, and
*<...>* for arguments where you are expected to supply some value.
# COMMANDS
The following commands may only be used in the configuration file.
*bar* [<bar-id>] <bar-subcommands...>
For details on bar subcommands, see *sway-bar*(5).
*default_orientation* horizontal|vertical|auto
Sets the default container layout for tiled containers.
*include* <path>
Includes another file from _path_. _path_ can be either a full path or a
path relative to the parent config, and expands shell syntax (see
*wordexp*(3) for details). The same include file can only be included once;
subsequent attempts will be ignored.
*swaybg_command* <command>
Executes custom background _command_. Default is _swaybg_. Refer to
*sway-output*(5) for more information.
It can be disabled by setting the command to a single dash:
_swaybg\_command -_
*swaynag_command* <command>
Executes custom command for _swaynag_. Default is _swaynag_. Additional
arguments may be appended to the end. This should only be used to either
direct sway to call swaynag from a custom path or to provide additional
arguments. This should be placed at the top of the config for the best
results.
It can be disabled by setting the command to a single dash:
_swaynag\_command -_
*xwayland* enable|disable
Enables or disables Xwayland support, which allows X11 applications to be
used.
The following commands cannot be used directly in the configuration file.
They are expected to be used with *bindsym* or at runtime through *swaymsg*(1).
*border* none|normal|csd|pixel [<n>]
Set border style for focused window. _normal_ includes a border of
thickness _n_ and a title bar. _pixel_ is a border without title bar _n_
pixels thick. Default is _normal_ with border thickness 2. _csd_ is short
for client-side-decorations, which allows the client to draw its own
decorations.
*border* toggle
Cycles through the available border styles.
*exit*
Exit sway and end your Wayland session.
*floating* enable|disable|toggle
Make focused view floating, non-floating, or the opposite of what it is now.
<criteria> *focus*
Moves focus to the container that matches the specified criteria.
*focus* up|right|down|left
Moves focus to the next container in the specified direction.
*focus* child
Moves focus to the last-focused child of the focused container.
*focus* parent
Moves focus to the parent of the focused container.
*focus* output up|right|down|left
Moves focus to the next output in the specified direction.
*focus* output <name>
Moves focus to the named output.
*focus tiling*
Sets focus to the last focused tiling container.
*focus floating*
Sets focus to the last focused floating container.
*focus* mode_toggle
Moves focus between the floating and tiled layers.
*fullscreen* [enable|disable|toggle] [global]
Makes focused view fullscreen, non-fullscreen, or the opposite of what it
is now. If no argument is given, it does the same as _toggle_. If _global_
is specified, the view will be fullscreen across all outputs.
*gaps* inner|outer|horizontal|vertical|top|right|bottom|left all|current
set|plus|minus <amount>
Changes the _inner_ or _outer_ gaps for either _all_ workspaces or the
_current_ workspace. _outer_ gaps can be altered per side with _top_,
_right_, _bottom_, and _left_ or per direction with _horizontal_ and
_vertical_.
*inhibit_idle* focus|fullscreen|open|none|visible
Set/unset an idle inhibitor for the view. _focus_ will inhibit idle when
the view is focused by any seat. _fullscreen_ will inhibit idle when the
view is fullscreen (or a descendant of a fullscreen container) and is
visible. _open_ will inhibit idle until the view is closed (or the
inhibitor is unset/changed). _visible_ will inhibit idle when the view is
visible on any output. _none_ will remove any existing idle inhibitor for
the view.
This can also be used with criteria to set an idle inhibitor for any
existing view or with _for_window_ to set idle inhibitors for future views.
*layout* default|splith|splitv|stacking|tabbed
Sets the layout mode of the focused container.
*layout* toggle [split|all]
Cycles the layout mode of the focused container though a preset list of
layouts. If no argument is given, then it cycles through stacking, tabbed
and the last split layout. If "split" is given, then it cycles through
splith and splitv. If "all" is given, then it cycles through every layout.
*layout* toggle [split|tabbed|stacking|splitv|splith] [split|tabbed|stacking|splitv|splith]...
Cycles the layout mode of the focused container through a list of layouts.
*move* left|right|up|down [<px> px]
Moves the focused container in the direction specified. If the container,
the optional _px_ argument specifies how many pixels to move the container.
If unspecified, the default is 10 pixels. Pixels are ignored when moving
tiled containers.
*move* [absolute] position <pos_x> [px] <pos_y> [px]
Moves the focused container to the specified position in the workspace. If
_absolute_ is used, the position is relative to all outputs.
*move* [absolute] position center
Moves the focused container to be centered on the workspace. If _absolute_
is used, it is moved to the center of all outputs.
*move* position cursor|mouse|pointer
Moves the focused container to be centered on the cursor.
*move* [container|window] [to] mark <mark>
Moves the focused container to the specified mark.
*move* [--no-auto-back-and-forth] [container|window] [to] workspace [number] <name>
Moves the focused container to the specified workspace. The string "number"
is optional and is used to match a workspace with the same number, even if
it has a different name.
*move* [container|window] [to] workspace prev|next|current
Moves the focused container to the previous, next or current workspace on
this output, or if no workspaces remain, the previous or next output.
*move* [container|window] [to] workspace prev_on_output|next_on_output
Moves the focused container to the previous or next workspace on this
output, wrapping around if already at the first or last workspace.
*move* [container|window] [to] workspace back_and_forth
Moves the focused container to previously focused workspace.
*move* [container|window] [to] output <name-or-id>
Moves the focused container to the specified output.
*move* [container|window] [to] output up|right|down|left
Moves the focused container to next output in the specified
direction.
*move* [container|window] [to] scratchpad
Moves the focused container to the scratchpad.
*move* workspace [to] output <name-or-id>
Moves the focused workspace to the specified output.
*move* workspace to [output] <name-or-id>
Moves the focused workspace to the specified output.
*move* workspace [to] output up|right|down|left
Moves the focused workspace to next output in the specified direction.
*move* workspace to [output] up|right|down|left
Moves the focused workspace to next output in the specified direction.
*nop* <comment>
A no operation command that can be used to override default behaviour. The
optional comment argument is ignored, but logged for debugging purposes.
*reload*
Reloads the sway config file and applies any changes.
*rename workspace* [<old_name>] to <new_name>
Rename either <old_name> or the focused workspace to the <new_name>
*resize* shrink|grow width|height [<amount> [px|ppt]]
Resizes the currently focused container by _amount_, specified in pixels or
percentage points. If the units are omitted, floating containers are resized
in px and tiled containers by ppt. _amount_ will default to 10 if omitted.
*resize set* height <height> [px|ppt]
Sets the height of the container to _height_, specified in pixels or
percentage points. If the units are omitted, floating containers are
resized in px and tiled containers by ppt. If _height_ is 0, the container
will not be resized.
*resize set* [width] <width> [px|ppt]
Sets the width of the container to _width_, specified in pixels or
percentage points. If the units are omitted, floating containers are
resized in px and tiled containers by ppt. If _width_ is 0, the container
will not be resized.
*resize set* [width] <width> [px|ppt] [height] <height> [px|ppt]
Sets the width and height of the container to _width_ and _height_,
specified in pixels or percentage points. If the units are omitted,
floating containers are resized in px and tiled containers by ppt. If
_width_ or _height_ is 0, the container will not be resized on that axis.
*scratchpad show*
Shows a window from the scratchpad. Repeatedly using this command will
cycle through the windows in the scratchpad.
*split* vertical|v|horizontal|h|toggle|t
Splits the current container, vertically or horizontally. When _toggle_ is
specified, the current container is split opposite to the parent
container's layout.
*splith*
Equivalent to *split horizontal*
*splitv*
Equivalent to *split vertical*
*splitt*
Equivalent to *split toggle*
*sticky* enable|disable|toggle
"Sticks" a floating window to the current output so that it shows up on all
workspaces.
*swap* container with id|con_id|mark <arg>
Swaps the position, geometry, and fullscreen status of two containers. The
first container can be selected either by criteria or focus. The second
container can be selected by _id_, _con_id_, or _mark_. _id_ can only be
used with xwayland views. If the first container has focus, it will retain
focus unless it is moved to a different workspace or the second container
becomes fullscreen on the same workspace as the first container. In either
of those cases, the second container will gain focus.
*title_format* <format>
Sets the format of window titles. The following placeholders may be used:
%title - The title supplied by the window
%app_id - The wayland app ID (applicable to wayland windows only)
%class - The X11 classname (applicable to xwayland windows only)
%instance - The X11 instance (applicable to xwayland windows only)
%shell - The protocol the window is using (typically xwayland or
xdg_shell)
This command is typically used with *for_window* criteria. For example:
for_window [title="."] title_format "<b>%title</b> (%app_id)"
Note that markup requires pango to be enabled via the *font* command.
The default format is "%title".
The following commands may be used either in the configuration file or at
runtime.
*assign* <criteria> [→] [workspace] [number] <workspace>
Assigns views matching _criteria_ (see *CRITERIA* for details) to
_workspace_. The → (U+2192) is optional and cosmetic. This command is
equivalent to:
for_window <criteria> move container to workspace <workspace>
*assign* <criteria> [→] output left|right|up|down|<name>
Assigns views matching _criteria_ (see *CRITERIA* for details) to the
specified output. The → (U+2192) is optional and cosmetic. This command is
equivalent to:
for_window <criteria> move container to output <output>
*bindsym* [--whole-window] [--border] [--exclude-titlebar] [--release] [--locked] [--to-code] [--input-device=<device>] [--no-warn] <key combo> <command>
Binds _key combo_ to execute the sway command _command_ when pressed. You
may use XKB key names here (*xev*(1) is a good tool for discovering these).
With the flag _--release_, the command is executed when the key combo is
released. Unless the flag _--locked_ is set, the command will not be run
when a screen locking program is active. If _input-device_ is given, the
binding will only be executed for that input device and will be executed
instead of any binding that is generic to all devices. By default, if you
overwrite a binding, swaynag will give you a warning. To silence this, use
the _--no-warn_ flag.
Bindings to keysyms are layout-dependent. This can be changed with the
_--to-code_ flag. In this case, the keysyms will be translated into the
corresponding keycodes in the first configured layout.
Mouse bindings operate on the container under the cursor instead of the
container that has focus. Mouse buttons can either be specified in the form
_button[1-9]_ or by using the name of the event code (ex _BTN\_LEFT_ or
_BTN\_RIGHT_). For the former option, the buttons will be mapped to their
values in X11 (1=left, 2=middle, 3=right, 4=scroll up, 5=scroll down,
6=scroll left, 7=scroll right, 8=back, 9=forward). For the latter option,
you can find the event names using _libinput debug-events_.
_--whole-window_, _--border_, and _--exclude-titlebar_ are mouse-only options
which affect the region in which the mouse bindings can be triggered. By
default, mouse bindings are only triggered when over the title bar. With the
_--border_ option, the border of the window will be included in this region.
With the _--whole-window_ option, the cursor can be anywhere over a window
including the title, border, and content. _--exclude-titlebar_ can be used in
conjunction with any other option to specify that the titlebar should be
excluded from the region of consideration.
If _--whole-window_ is given, the command can be triggered when the cursor
is over an empty workspace. Using a mouse binding over a layer surface's
exclusive region is not currently possible.
Example:
```
# Execute firefox when alt, shift, and f are pressed together
bindsym Mod1+Shift+f exec firefox
```
*bindcode* [--whole-window] [--border] [--exclude-titlebar] [--release] [--locked] [--input-device=<device>] [--no-warn] <code> <command>
is also available for binding with key/button codes instead of key/button names.
*bindswitch* [--locked] [--no-warn] <switch>:<state> <command>
Binds <switch> to execute the sway command _command_ on state changes.
Supported switches are _lid_ (laptop lid) and _tablet_ (tablet mode)
switches. Valid values for _state_ are _on_, _off_ and _toggle. These
switches are on when the device lid is shut and when tablet mode is active
respectively. _toggle_ is also supported to run a command both when the
switch is toggled on or off.
Unless the flag _--locked_ is set, the command will not be run
when a screen locking program is active. By default, if you
overwrite a binding, swaynag will give you a warning. To silence this, use
the _--no-warn_ flag.
Example:
```
# Show the virtual keyboard when tablet mode is entered.
bindswitch tablet:on busctl call --user sm.puri.OSK0 /sm/puri/OSK0 sm.puri.OSK0 SetVisible b true
# Log a message when the laptop lid is opened or closed.
bindswitch lid:toggle exec echo "Lid moved"
```
*client.<class>* <border> <background> <text> <indicator> <child_border>
Configures the color of window borders and title bars. All 5 colors are
required, with the exception of *client.background*, which requires exactly
one. Colors may be specified in hex, either as _#RRGGBB_ or _#RRGGBBAA_.
The available classes are:
*client.background*
Ignored (present for i3 compatibility).
*client.focused*
The window that has focus.
*client.focused_inactive*
The most recently focused view within a container which is not focused.
*client.placeholder*
Ignored (present for i3 compatibility).
*client.unfocused*
A view that does not have focus.
*client.urgent*
A view with an urgency hint. *Note*: Native Wayland windows do not
support urgency. Urgency only works for Xwayland windows.
The meaning of each color is:
_border_
The border around the title bar.
_background_
The background of the title bar.
_text_
The text color of the title bar.
_indicator_
The color used to indicate where a new view will open. In a tiled
container, this would paint the right border of the current view if a
new view would be opened to the right.
_child_border_
The border around the view itself.
The default colors are:

*default_border* normal|none|pixel [<n>]
Set default border style for new tiled windows.
*default_floating_border* normal|none|pixel [<n>]
Set default border style for new floating windows. This only applies to
windows that are spawned in floating mode, not windows that become floating
afterwards.
*exec* <shell command>
Executes _shell command_ with sh.
*exec_always* <shell command>
Like *exec*, but the shell command will be executed _again_ after *reload*.
*floating_maximum_size* <width> x <height>
Specifies the maximum size of floating windows. -1 x -1 removes the upper
limit. The default is 0 x 0, which will use the width and height of the
entire output layout as the maximums
*floating_minimum_size* <width> x <height>
Specifies the minimum size of floating windows. The default is 75 x 50.
*floating_modifier* <modifier> [normal|inverse]
When the _modifier_ key is held down, you may hold left click to move
windows, and right click to resize them. If _inverse_ is specified, left
click is used for resizing and right click for moving.
*floating_scroll* up|right|down|left [command]
Sets a command to be executed when the mouse wheel is scrolled in the
specified direction while holding the floating modifier. Resets the
command, when given no arguments.
*focus_follows_mouse* yes|no|always
If set to _yes_, moving your mouse over a window will focus that window. If
set to _always_, the window under the cursor will always be focused, even
after switching between workspaces.
*focus_wrapping* yes|no|force
This option determines what to do when attempting to focus over the edge
of a container. If set to _no_, the focused container will retain focus,
if there are no other containers in the direction. If set to _yes_, focus
will be wrapped to the opposite edge of the container, if there are no
other containers in the direction. If set to _force_, focus will be wrapped
to the opposite edge of the container, even if there are other containers
in the direction. Default is _yes_.
*font* <font>
Sets font for use in title bars in Pango format.
*titlebar_border_thickness* <thickness>
Thickness of the titlebar border in pixels
*titlebar_padding* <horizontal> [<vertical>]
Padding of the text in the titlebar. _horizontal_ value affects horizontal
padding of the text while _vertical_ value affects vertical padding (space
above and below text). Padding includes titlebar borders so their value
should be greater than titlebar_border_thickness. If _vertical_ value is
not specified it is set to the _horizontal_ value.
*for_window* <criteria> <command>
Whenever a window that matches _criteria_ appears, run list of commands.
See *CRITERIA* for more details.
*gaps* inner|outer|horizontal|vertical|top|right|bottom|left <amount>
Sets default _amount_ pixels of _inner_ or _outer_ gap, where the inner
affects spacing around each view and outer affects the spacing around each
workspace. Outer gaps are in addition to inner gaps. To reduce or remove
outer gaps, outer gaps can be set to a negative value. _outer_ gaps can
also be specified per side with _top_, _right_, _bottom_, and _left_ or
per direction with _horizontal_ and _vertical_.
This affects new workspaces only, and is used when the workspace doesn't
have its own gaps settings (see: workspace <ws> gaps ...).
*hide_edge_borders* [--i3] none|vertical|horizontal|both|smart|smart_no_gaps
Hides window borders adjacent to the screen edges. Default is _none_. The
_--i3_ option enables i3-compatible behavior to hide the title bar on tabbed
and stacked containers with one child.
*input* <input_device> <input-subcommands...>
For details on input subcommands, see *sway-input*(5).
\* may be used in lieu of a specific device name to configure all input
devices. A list of input device names may be obtained via *swaymsg -t
get_inputs*.
*seat* <seat> <seat-subcommands...>
For details on seat subcommands, see *sway-input*(5).
*kill*
Kills (closes) the currently focused container and all of its children.
*smart_borders* on|no_gaps|off
If smart_borders are _on_, borders will only be enabled if the workspace
has more than one visible child (identical to _hide_edge_borders_ smart).
If smart_borders is set to _no_gaps_, borders will only be enabled if the
workspace has more than one visible child and gaps equal to zero.
*smart_gaps* on|off
If smart_gaps are _on_ gaps will only be enabled if a workspace has more
than one child.
*mark* --add|--replace [--toggle] <identifier>
Marks are arbitrary labels that can be used to identify certain windows and
then jump to them at a later time. By default, *mark* sets _identifier_ as
the only mark on a window. _--add_ will instead add _identifier_ to the
list of current marks. If _--toggle_ is specified mark will remove
_identifier_ if it is already marked.
*mode* <mode>
Switches to the specified mode. The default mode _default_.
*mode* [--pango_markup] <mode> <mode-subcommands...>
The only valid _mode-subcommands..._ are *bindsym*, *bindcode*,
*bindswitch*, and *set*. If _--pango_markup_ is given, then _mode_ will be
interpreted as pango markup.
*mouse_warping* output|container|none
If _output_ is specified, the mouse will be moved to new outputs as you
move focus between them. If _container_ is specified, the mouse will be
moved to the middle of the container on switch. Default is _output_.
*no_focus* <criteria>
Prevents windows matching <criteria> from being focused automatically when
they're created. This has no effect on the first window in a workspace.
*output* <output_name> <output-subcommands...>
For details on output subcommands, see *sway-output*(5).
\* may be used in lieu of a specific output name to configure all outputs.
A list of output names may be obtained via *swaymsg -t get_outputs*.
*popup_during_fullscreen* smart|ignore|leave_fullscreen
Determines what to do when a fullscreen view opens a dialog.
If _smart_ (the default), the dialog will be displayed. If _ignore_, the
dialog will not be rendered. If _leave_fullscreen_, the view will exit
fullscreen mode and the dialog will be rendered.
*set* $<name> <value>
Sets variable $_name_ to _value_. You can use the new variable in the
arguments of future commands. When the variable is used, it can be escaped
with an additional $ (ie $$_name_) to have the replacement happen at run
time instead of when reading the config. However, it does not always make
sense for the variable to be replaced at run time since some arguments do
need to be known at config time.
*show_marks* yes|no
If *show_marks* is yes, marks will be displayed in the window borders.
Any mark that starts with an underscore will not be drawn even if
*show_marks* is yes. The default is _yes_.
*opacity* <value>
Set the opacity of the window between 0 (completely transparent) and 1
(completely opaque).
*tiling_drag* enable|disable|toggle
Sets whether or not tiling containers can be dragged with the mouse. If
enabled (default), the _floating_mod_ can be used to drag tiling, as well
as floating, containers. Using the left mouse button on title bars without
the _floating_mod_ will also allow the container to be dragged. _toggle_
should not be used in the config file.
*tiling_drag_threshold* <threshold>
Sets the threshold that must be exceeded for a container to be dragged by
its titlebar. This has no effect if _floating_mod_ is used or if
_tiling_drag_ is set to _disable_. Once the threshold has been exceeded
once, the drag starts and the cursor can come back inside the threshold
without stopping the drag. _threshold_ is multiplied by the scale of the
output that the cursor on. The default is 9.
*title_align* left|center|right
Sets the title alignment. If _right_ is selected and _show_marks_ is set
to _yes_, the marks will be shown on the _left_ side instead of the
_right_ side.
*unbindswitch* <switch>:<state>
Removes a binding for when <switch> changes to <state>.
*unbindsym* [--whole-window] [--border] [--exclude-titlebar] [--release] [--input-device=<device>] <key combo>
Removes the binding for _key combo_ that was previously bound with the
given flags. If _input-device_ is given, only the binding for that
input device will be unbound.
*unbindcode* [--whole-window] [--border] [--exclude-titlebar] [--release] [input-device=<device>] <code>
is also available for unbinding with key/button codes instead of key/button names.
*unmark* [<identifier>]
*unmark* will remove _identifier_ from the list of current marks on a
window. If _identifier_ is omitted, all marks are removed.
*urgent* enable|disable|allow|deny
Using _enable_ or _disable_ manually sets or unsets the window's urgent
state. Using _allow_ or _deny_ controls the window's ability to set itself
as urgent. By default, windows are allowed to set their own urgency.
*workspace* [--no-auto-back-and-forth] [number] <name>
Switches to the specified workspace. The string "number" is optional and is
used to sort workspaces.
*workspace* prev|next
Switches to the next workspace on the current output or on the next output
if currently on the last workspace.
*workspace* prev_on_output|next_on_output
Switches to the next workspace on the current output.
*workspace* back_and_forth
Switches to the previously focused workspace.
*workspace* <name> gaps inner|outer|horizontal|vertical|top|right|bottom|left
<amount>
Specifies that workspace _name_ should have the given gaps settings when it
is created.
*workspace* <name> output <outputs...>
Specifies that workspace _name_ should be shown on the specified _outputs_.
Multiple outputs can be listed and the first available will be used. If the
workspace gets placed on an output further down the list and an output that
is higher on the list becomes available, the workspace will be move to the
higher priority output.
*workspace_auto_back_and_forth* yes|no
When _yes_, repeating a workspace switch command will switch back to the
prior workspace. For example, if you are currently on workspace 1,
switch to workspace 2, then invoke the "workspace 2" command again, you
will be returned to workspace 1. Default is _no_.
*workspace_layout* default|stacking|tabbed
Specifies the initial layout for new workspaces.
# BAR CONTROL
*bar hidden_state* hide|show|toggle [<bar_id>]
Sets the hidden state of the bar (see *sway-bar*(5)), either individually,
by specifying a bar id, or if none is given, for all bar instances.
_toggle_ switches between _hide_ and _show_.
*bar mode* dock|hide|invisible|toggle [<bar_id>]
Sets the mode of the bar (see *sway-bar*(5)), either individually,
by specifying a bar id, or if none is given, for all bar instances.

# CRITERIA
A criteria is a string in the form of, for example:
```
[class="[Rr]egex.*" title="some title"]
```
The string contains one or more (space separated) attribute/value pairs. They
are used by some commands to choose which views to execute actions on. All
attributes must match for the criteria to match.
Criteria may be used with either the *for_window* or *assign* commands to
specify operations to perform on new views. A criteria may also be used to
perform specific commands (ones that normally act upon one window) on all views
that match that criteria. For example:
Focus on a window with the mark "IRC":
```
[con_mark="IRC"] focus
```
Kill all windows with the title "Emacs":
```
[class="Emacs"] kill
```
Mark all Firefox windows with "Browser":
```
[class="Firefox"] mark Browser
```
The following attributes may be matched with:
*app_id*
Compare value against the app id. Can be a regular expression. If value is
\_\_focused\_\_, then the app id must be the same as that of the currently
focused window.
*class*
Compare value against the window class. Can be a regular expression. If
value is \_\_focused\_\_, then the window class must be the same as that of
the currently focused window.
*con_id*
Compare against the internal container ID, which you can find via IPC. If
value is \_\_focused\_\_, then the id must be the same as that of the
currently focused window.
*con_mark*
Compare against the window marks. Can be a regular expression.
*floating*
Matches floating windows.
*id*
Compare value against the X11 window ID. Must be numeric.
*instance*
Compare value against the window instance. Can be a regular expression. If
value is \_\_focused\_\_, then the window instance must be the same as that
of the currently focused window.
*shell*
Compare value against the window shell, such as "xdg_shell" or "xwayland".
Can be a regular expression. If value is \_\_focused\_\_, then the shell
must be the same as that of the currently focused window.
*tiling*
Matches tiling windows.
*title*
Compare against the window title. Can be a regular expression. If value is
\_\_focused\_\_, then the window title must be the same as that of the
currently focused window.
*urgent*
Compares the urgent state of the window. Can be "first", "last", "latest",
"newest", "oldest" or "recent".
*window_role*
Compare against the window role (WM_WINDOW_ROLE). Can be a regular
expression. If value is \_\_focused\_\_, then the window role must be the
same as that of the currently focused window.
*window_type*
Compare against the window type (\_NET_WM_WINDOW_TYPE). Possible values
are normal, dialog, utility, toolbar, splash, menu, dropdown_menu,
popup_menu, tooltip and notification.
*workspace*
Compare against the workspace name for this view. Can be a regular
expression. If the value is \_\_focused\_\_, then all the views on the
currently focused workspace matches.
