RIVERCTL(1)
riverctl - command-line interface for controlling river
riverctl [options] command [command specific arguments]
riverctl is a command-line utility used to control and configure river over the Wayland protocol.
-h Print a help message and exit.
-version Print the version number and exit.
This manual uses terms that some may find confusing, coming mostly from their usage among other Wayland projects.
The compositor, display server, Wayland server etc. are ways to refer to river itself.
A view (or toplevel) is what most call a window.
An output is a synonym for a screen or monitor.
Tags are river's way of dividing views of an output into groups (not necessarily disjunct), an analogy to workspaces.
close Close the focused view.
exit Exit the compositor, terminating the Wayland session.
focus-output next|previous|up|right|down|left|name Focus the next or previous output, the closest output in any direction or an output by name.
focus-view [-skip-floating] next|previous|up|down|left|right Focus the next or previous view in the stack or the closest view in any direction.
- *-skip-floating*: Skip floating views, only focusing tiled ones.move up|down|left|right delta Move the focused view in the specified direction by delta logical pixels. The view will be set to floating.
resize horizontal|vertical delta Resize the focused view along the given axis by delta logical pixels. The view will be set to floating.
snap up|down|left|right Snap the focused view to the specified screen edge. The view will be set to floating.
send-to-output [-current-tags] next|previous|up|right|down|left|name Send the focused view to the next or previous output, the closest output in any direction or to an output by name.
- *-current-tags*: Assign the currently focused tags of the destination
output to the view.spawn shell_command
Run shell_command using /bin/sh -c _shell_command_. Note that
spawn only takes a single argument. To spawn a command taking
multiple arguments, wrapping the command in quotes is recommended.
swap next|previous|up|down|left|right Swap the focused view with the next or previous non-floating view in the stack or the closest non-floating view in any direction.
toggle-float Toggle the floating state of the focused view.
toggle-fullscreen Toggle the fullscreen state of the focused view.
zoom Bump the focused view to the top of the layout stack. If the top view in the stack is already focused, bump the second view.
default-layout namespace Set the layout namespace to be used by all outputs by default.
output-layout namespace Set the layout namespace of currently focused output, overriding the value set with default-layout if any.
send-layout-cmd namespace command Send command to the layout generator on the currently focused output with the given namespace, if any. What commands a layout generator understands depends on the layout generator. For rivertile, see the documentation in the rivertile(1) man page.
Tags are similar to workspaces but more flexible. You can assign views multiple tags and focus multiple tags simultaneously. Bitfields are used to describe sets of tags when interfacing with river. As such, the following commands take a normal base 10 number as their argument but the semantics are best understood in binary. The binary number 000000001 represents a set containing only tag 1 while 100001101 represents a set containing tags 1, 3, 4, and 9.
When a view spawns it is assigned the currently focused tags of the output.
At least one tag must always be focused and each view must be assigned at least one tag. Operations that would violate either of these requirements are ignored by river.
set-focused-tags tags Show views with tags corresponding to the set bits of tags on the currently focused output.
set-view-tags tags Assign the currently focused view the tags corresponding to the set bits of tags.
toggle-focused-tags tags Toggle visibility of views with tags corresponding to the set bits of tags on the currently focused output.
toggle-view-tags tags Toggle the tags of the currently focused view corresponding to the set bits of tags.
spawn-tagmask tagmask Set a tagmask to filter the tags assigned to newly spawned views. This mask will be applied to the tags of new views with a bitwise and. If, for example, the tags 000011111 are focused and the spawn tagmask is 111110001, a new view will be assigned the tags 000010001. If no tags would remain after filtering, the tagmask is ignored.
focus-previous-tags Sets tags to their previous value on the currently focused output, allowing jumping back and forth between 2 tag setups.
send-to-previous-tags Assign the currently focused view the previous tags of the currently focused output.
Mappings are modal in river. Each mapping is associated with a mode and is only active while in that mode. There are two special modes: "normal" and "locked". The normal mode is the initial mode on startup. The locked mode is automatically entered while the session is locked (e.g. due to a screenlocker). It cannot be entered or exited manually.
The following modifiers are available for use in mappings:
- Shift
- Control
- Mod1 (Alt)
- Mod3
- Mod4 (Super)
- Mod5
- NoneAlt and Super are aliases for Mod1 and Mod4 respectively. None allows creating a mapping without modifiers.
Keys are specified by their XKB keysym name. See /usr/include/xkbcommon/xkbcommon-keysyms.h for the complete list.
Mouse buttons are specified by Linux input event code names. The most commonly used values are:
- BTN_LEFT - left mouse button
- BTN_RIGHT - right mouse button
- BTN_MIDDLE - middle mouse buttonA complete list may be found in /usr/include/linux/input-event-codes.h
declare-mode name Create a new mode called name.
enter-mode name Switch to given mode if it exists.
map [-release|-repeat|-layout index] mode modifiers key command Run command when key is pressed while modifiers are held down and in the specified mode.
- *-release*: if passed activate on key release instead of key press
- *-repeat*: if passed activate repeatedly until key release; may not
be used with *-release*
- *-layout*: if passed, a specific layout is pinned to the mapping.
When the mapping is checked against a pressed key, this layout is
used to translate the key independent of the active layout
- _index_: zero-based index of a layout set with the *keyboard-layout*
command. If the index is out of range, the *-layout* option will
have no effect
- _mode_: name of the mode for which to create the mapping
- _modifiers_: one or more of the modifiers listed above, separated
by a plus sign (+).
- _key_: an XKB keysym name as described above
- _command_: any command that may be run with riverctlmap-pointer mode modifiers button action|command Move or resize views or run command when button and modifiers are held down while in the specified mode. The view under the cursor will be focused.
- _mode_: name of the mode for which to create the mapping
- _modifiers_: one or more of the modifiers listed above, separated
by a plus sign (+).
- _button_: the name of a Linux input event code as described above
- _action_: one of the following values:
- move-view
- resize-view
- _command_: any command that may be run with riverctlmap-switch mode lid|tablet state command Run command when river receives a certain switch event.
- _mode_: name of the mode for which to create the mapping
- _lid_|_tablet_: 'lid switch' and 'tablet mode switch' are supported
- _state_:
- possible states for _lid_:
- close
- open
- possible states for _tablet_:
- on
- off
- _command_: any command that may be run with riverctlunmap [-release] mode modifiers key Remove the mapping defined by the arguments:
- *-release*: if passed unmap the key release instead of the key press
- _mode_: name of the mode for which to remove the mapping
- _modifiers_: one or more of the modifiers listed above, separated
by a plus sign (+).
- _key_: an XKB keysym name as described aboveunmap-pointer mode modifiers button Remove the pointer mapping defined by the arguments:
- _mode_: name of the mode for which to remove the mapping
- _modifiers_: one or more of the modifiers listed above, separated
by a plus sign (+).
- _button_: the name of a Linux input event code as described aboveunmap-switch mode lid|tablet state Remove the switch mapping defined by the arguments:
- _mode_: name of the mode for which to remove the mapping
- _lid_|_tablet_: the switch for which to remove the mapping
- _state_: a state as listed aboveRules match the app-id and title of views against a glob pattern. A glob is a string that may optionally have an * at the beginning and/or end. An * in a glob matches zero or more arbitrary characters in the app-id or title.
For example, abc is matched by a*, *a*, *b*, *c, abc, and * but not matched by *a, b*, *b, c*, or ab. Note that * matches everything while ** and the empty string are invalid.
rule-add [-app-id glob|-title glob] action [arguments] Add a rule that applies an action to views with app-id and title matched by the respective glob. Omitting -app-id or -title is equivalent to passing -app-id * or -title *. Some actions require one or more arguments.
The supported _action_ types are:
- *float*: Make the view floating. Applies only to new views.
- *no-float*: Don't make the view floating. Applies only to
new views.
- *ssd*: Use server-side decorations for the view. Applies to new
and existing views.
- *csd*: Use client-side decorations for the view. Applies to new
and existing views.
- *tags*: Set the initial tags of the view. Requires the tags as
an argument. Applies only to new views.
- *output*: Set the initial output of the view. Requires the output
as an argument. Applies only to new views. The output can be specified
either by connector name (such as _HDMI-A-1_, or _DP-2_), or by
identifier in the form of _MAKE MODEL SERIAL_, for example for an output
with make: _HP Inc._, model: _HP 22w_, and serial: _CNC93720WF_, the
identifier would be: _HP Inc. HP 22w CNC93720WF_. If the make, model, or
serial is unknown, the word "Unknown" is used instead.
- *position*: Set the initial position of the view, clamping to the
bounds of the output. Requires x and y coordinates of the view as
arguments, both of which must be non-negative. Applies only to new views.
- *dimensions*: Set the initial dimensions of the view, clamping to the
constraints of the view. Requires width and height of the view as
arguments, both of which must be non-negative. Applies only to new views.
- *fullscreen*: Make the view fullscreen. Applies only to new views.
- *no-fullscreen*: Don't make the view fullscreen. Applies only to
new views.
Both *float* and *no-float* rules are added to the same list,
which means that adding a *no-float* rule with the same arguments
as a *float* rule will overwrite it. The same holds for *ssd* and
*csd*, *fullscreen* and *no-fullscreen* rules.
If multiple rules in a list match a given view the most specific
rule will be applied. For example with the following rules
```
app-id title action
foo bar ssd
foo * csd
* bar csd
* baz ssd
```
a view with app-id 'foo' and title 'bar' would get ssd despite matching
two csd rules as the first rule is most specific. Furthermore a view
with app-id 'foo' and title 'baz' would get csd despite matching the
last rule in the list since app-id specificity takes priority over
title specificity.
If a view is not matched by any rule, river will respect the csd/ssd
wishes of the client and may start the view floating based on simple
heuristics intended to catch popup-like views.
If a view is started fullscreen or is not floating, then *position* and
*dimensions* rules will have no effect A view must be matched by a *float*
rule in order for them to take effect.rule-del [-app-id glob|-title glob] action Delete a rule created using rule-add with the given arguments.
list-rules float|ssd|tags|position|dimensions|fullscreen Print the specified rule list. The output is ordered from most specific to least specific, the same order in which views are checked against when searching for a match. Only the first matching rule in the list has an effect on a given view.
default-attach-mode top|bottom|above|below|after Set the attach mode to be used by all outputs by default.
Possible values:
- top: Prepends the newly spawned view at the top of the stack.
- bottom: Appends the newly spawned view at the bottom of the stack.
- above: Inserts the newly spawned view above the currently focused view.
- below: Inserts the newly spawned view below the currently focused view.
- after <N>: Inserts the newly spawned view after N views in the stack.
Note that the deprecated *attach-mode* command is aliased to
*default-attach-mode* for backwards compatibility.output-attach-mode top|bottom|above|below|after Set the attach mode of the currently focused output, overriding the value of default-attach-mode if any.
background-color 0xRRGGBB|0xRRGGBBAA Set the background color.
border-color-focused 0xRRGGBB|0xRRGGBBAA Set the border color of focused views.
border-color-unfocused 0xRRGGBB|0xRRGGBBAA Set the border color of unfocused views.
border-color-urgent 0xRRGGBB|0xRRGGBBAA Set the border color of urgent views.
border-width pixels Set the border width to pixels.
focus-follows-cursor disabled|normal|always There are three available modes:
- _disabled_: Moving the cursor does not affect focus. This is
the default.
- _normal_: Moving the cursor over a view will focus that view.
Moving the cursor within a view will not re-focus that view if
focus has moved elsewhere.
- _always_: Moving the cursor will always focus whatever view is
under the cursor.
If the view to be focused is on an output that does not have focus,
focus is switched to that output.hide-cursor timeout timeout Hide the cursor if it wasn't moved in the last timeout milliseconds until it is moved again. The default value is 0, which disables automatically hiding the cursor. Show the cursor again on any movement.
hide-cursor when-typing enabled|disabled Hide the cursor when pressing any non-modifier key. Show the cursor again on any movement.
set-cursor-warp disabled|on-output-change|on-focus-change Set the cursor warp mode. There are two available modes:
- _disabled_: Cursor will not be warped. This is the default.
- _on-output-change_: When a different output is focused, the cursor will be
warped to its center.
- _on-focus-change_: When a different view/output is focused, the cursor will be
warped to its center.set-repeat rate delay Set the keyboard repeat rate to rate key repeats per second and repeat delay to delay milliseconds.
xcursor-theme theme_name [size] Set the xcursor theme to theme_name and optionally set the size. The theme of the default seat determines the default for Xwayland and is made available through the XCURSOR_THEME and XCURSOR_SIZE environment variables.
list-inputs List all input devices.
list-input-configs List all input configurations.
keyboard-layout [-rules rules] [-model model] [-variant variant]
[-options options] layout
Set the XKB layout for all keyboards. Defaults from libxkbcommon are used for
everything left unspecified. Note that layout may be a comma separated list
of layouts (e.g. "us,de") which may be switched between using various key
combinations configured through the options argument (e.g. -options
"grp:ctrl_space_toggle"). See xkeyboard-config(7) for possible values and
more information.
keyboard-layout-file path Set the XKB layout for all keyboards from an XKB keymap file at the provided path. Documentation for the XKB keymap file format can be found at the following URL: https://xkbcommon.org/doc/current/keymap-text-format-v1.html
keyboard-group-create group_name Create a keyboard group. A keyboard group collects multiple keyboards in a single logical keyboard. This means that all state, like the active modifiers, is shared between the keyboards in a group.
keyboard-group-destroy group_name Destroy the keyboard group with the given name. All attached keyboards will be released, making them act as separate devices again.
keyboard-group-add group_name input_device_name Add a keyboard to a keyboard group, identified by the keyboard's input device name. Any currently connected and future keyboards with the given name will be added to the group. Simple globbing patterns are supported, see the rules section for further information on globs.
keyboard-group-remove group_name input_device_name Remove a keyboard from a keyboard group, identified by the keyboard's input device name.
The input command can be used to create a configuration rule for an input device identified by its name. The name of an input device consists of its type, its numerical vendor id, its numerical product id and finally its self-advertised name, separated by -. Simple globbing patterns are supported, see the rules section for further information on globs.
A list of all device properties that can be configured may be found below. However note that not every input device supports every property.
