NAME

       herbstluftwm - a manual tiling window manager for X

SYNOPSIS

       herbstluftwm [OPTION ...]

DESCRIPTION

       Starts the herbstluftwm window manager on DISPLAY. It also listens for calls from
       herbstclient(1) and executes them. The list of available COMMANDS is listed below.

       OPTION can be:

       -v, --version
           print version and exit

       -h, --help
           print a short help and exit

       -c, --autostart PATH
           use PATH as autostart file instead of the one in $XDG_CONFIG_HOME

       --replace
           Replace existing window manager.

       -l, --locked
           Initially set the monitors_locked setting to 1

       --exit-on-xerror
           Make herbstluftwm exit whenever xlib reports an error. This may only be activated for
           automated testing and never for actual sessions.

       --no-transparency
           Disable true transparency.

       --no-tag-import
           Do not preserve the tags (virtual desktops) from a previous running window manager.

       --verbose
           print verbose information to stderr. This can be switched at run-time by the verbose
           setting.

       This manual documents the scripting and configuration interface. For a more verbose
       introduction see herbstluftwm-tutorial(7).

TILING ALGORITHM

       The basic tiling concept is that the layout is represented by a binary tree. On startup
       you see one big frame across the entire screen. A frame fulfills exactly one of the
       following conditions:

        1. Frame contains windows:

           It shows some clients and arranges them. The available layout algorithms are:

           •   vertical - clients are placed below each other

           •   horizontal - clients are placed next to each other

           •   max - all clients are maximized in this frame

           •   grid - clients are arranged in an almost quadratic grid

        2. Frame is split into subframes:

           It is split into exactly two subframes in a configurable fraction either in a vertical
           or horizontal way. So it produces two frames which fulfill the same conditions (new
           frames always are about to contain windows). If you split a frame that already
           contains windows, the windows are inherited by the first new child frame.

       If a new window appears, it is put in the currently focused frame. Only the leaves of the
       frame tree can be focused.

       A frame can be removed, it is then merged with its neighbour frame. Due to the layout
       structure of a binary tree, each frame (i.e. node in binary tree) has exactly one
       neighbour.

       The analogy to a binary tree is explained the best way with a small example: On startup
       you have a simple binary tree, with one frame that can contain clients:

           C

       When splitting it (e.g. with the command split vertical 0.5) you will get this:

             V
            / \
           C   C

       You also can split the left frame horizontally and you will get:

               V
              / \
             H   C
            / \
           C   C

       If you change the focus to the client on the right and remove this frame, it will be
       merged with the left subtree and you will get:

             H
            / \
           C   C

       The layout command prints the current layout of all tags as a tree.

FRAME INDEX

       The exact position of a frame in the layout tree may be described by its index which is
       just a string of characters. The lookup algorithm starts at the root frame and interprets
       the index string character by character as follows:

       •   0: select the first subtree

       •   1: select the second subtree

       •   .: select the subtree having the focus

       •   /: select the subtree not having the focus

       •   @: select the frame having the focus. In contrast to ., this passes multiple layers
           all down to the focused leaf of the frame tree.

       •   p: select the parent tree

       •   e: finds a suitable empty frame: if the focused frame is not empty, this selects the
           closest frame that is empty (in any subtree)

       For example:

       •   An empty string refers to the root frame

       •   00 refers to the first subtree of the first subtree of the root frame.

       •   1e refers to the first empty frame in the second subtree.

       •   /@ refers to the focused frame within the unfocused "half" of the frame tree

       •   @p/ refers to the sibling of the focused frame

TAGS

       Tags are very similar to workspaces, virtual desktops or window groups. Each tag has one
       layout. There is a list of tags. You can add or remove tags dynamically.

MONITORS

       Monitors in herbstluftwm are totally independent of the actual physical screens. This
       means you can for example split your screen in two virtual monitors to view two tags at
       once on a big screen.

       Each monitor displays exactly one tag on a specified rectangle on the screen.

       Each monitor may have a name, which can be set via add_monitor and rename_monitor. It can
       be unset with the rename_monitor command. A monitor name is an arbitrary non-empty string
       which must not start with +, - or any digit.

       A monitor can be referenced in different ways:

       •   by its absolute index as listed in the list_monitors command.

       •   by its relative index: a + or - followed by a delta, e.g.: +3

       •   by its relative position to the focused monitor.  -l denotes the monitor left of the
           focused monitor, -r right of, -u above of, and -d below of, respectively.

       •   by "" (an empty string) which represents the current monitor.

       •   by its name.

COMMANDS

       herbstluftwm is controlled by internal commands, which can be executed via herbstclient(1)
       or via keybindings.

       quit
           Quits herbstluftwm.

       reload
           Executes the autostart file.

       version
           Prints the version of the running herbstluftwm instance.

       echo [ARGS ...]
           Prints all given ARGS separated by a single space and a newline afterwards.

       true
           Ignores all arguments and always returns success, i.e. 0.

       false
           Ignores all arguments and always returns failure, i.e. 1.

       help [OBJECT|ATTRIBUTE]
           Print help on a given object or attribute. For example:

           •   help clients.focus

           •   help monitors

           •   help types.color

       list_commands
           Lists all available commands.

       list_monitors
           List currently configured monitors with their index, area (as rectangle), name (if
           named) and currently viewed tag.

       list_rules
           Lists all active rules. Each line consists of all the parameters the rule was called
           with, plus its label, separated by tabs.

       list_keybinds
           Lists all bound keys with their associated command. Each line consists of one key
           combination and the command with its parameters separated by tabs.

           Warning
           Tabs within command parameters are not escaped!

       list_clients [--tag=TAG|--monitor=MONITOR] [--frame=FRAME_PATH|--floating|--tiling]
       [--title]
           Lists the window ids of all clients on the given TAG or MONITOR (or the current if
           unspecified). In addition to that, one can restrict to clients in a specific frame
           (--frame=) or to tiled or floated clients. The output is one line per client; if
           --title is given, then in addition to every client’s window id, its window title is
           printed in the same line.

       lock
           Increases the monitors_locked setting. Use this if you want to do multiple window
           actions at once (i.e. without repainting between the single steps). See also: unlock

       unlock
           Decreases the monitors_locked setting. If monitors_locked is changed to 0, then all
           monitors are repainted again. See also: lock

       keybind KEY COMMAND [ARGS ...]
           Adds a key binding. If there is already a binding for this KEY, it will be
           overwritten. When KEY is pressed, the internal COMMAND (with its ARGS) is executed. A
           key binding is a (possibly empty) list of modifiers (Mod1, Mod2, Mod3, Mod4, Mod5,
           Alt, Super, Control/Ctrl, Shift) and one key (see keysymdef.h for a list of keys).
           Modifiers and the key are concatenated with - or + as separator. If KEY is prefixed
           with Release- then the keybinding is only active during the corresponding key release
           event: that is, in order to run the key binding for Release-Mod1-Shift-p one needs to
           first press Mod1-Shift-p and then release p. Examples:

           •   keybind Mod4+Ctrl+q quit

           •   keybind Mod4-Shift-d attr clients.focus.decorated toggle

           •   keybind Mod1-Shift-space cycle_layout -1

           •   keybind Release-Mod4-Shift-p spawn scrot takes a screenshot when the p is released
               while Mod4 and Shift are still pressed.

       keyunbind KEY|-F|--all
           Removes the key binding for KEY. The syntax for KEY is defined in keybind. If -F or
           --all is given, then all key bindings will be removed.

       mousebind BUTTON ACTION [COMMAND ...]
           Adds a mouse binding for the floating mode. When BUTTON is pressed, the specified
           ACTION will be performed.  BUTTON has a similar syntax to the KEY argument of keybind:
           It consists of a list of modifiers (separated by - or +, valid modifiers are listed in
           the description of keybind) and exactly one button name:

           •   B1 or Button1B2 or Button2B3 or Button3B4 or Button4B5 or Button5

           ACTION must be one of the following actions:

           •   move: Moves the window by dragging the cursor.

           •   resize: Resizes the window by dragging a corner.

           •   zoom: Resizes the window into all four directions while keeping the center of the
               window constant.

           •   call: Only calls the specified COMMAND while client.dragged links to the client on
               which the BUTTON has been performed.

           While an ACTION is performed, client.dragged is the client which is dragged. E.g.:

           •   mousebind Mod1-Button3 zoommousebind Mod1-B4 call substitute WID clients.dragged.winid spawn transset-df
               --inc -i WID 0.05mousebind Mod1-B5 call substitute WID clients.dragged.winid spawn transset-df
               --dec -i WID -m 0.2 0.05

       drag WINID ACTION
           Starts dragging the specified client window WINID with the specified ACTION (see
           mousebind). E.g.  drag '' resize starts resizing the focused window.

       mouseunbind
           Removes all mouse bindings.

       spawn EXECUTABLE [ARGS ...]
           Spawns an EXECUTABLE with its ARGS. For details see man 3 execvp. Example:

           •   spawn xterm -e man 3 execvp

       wmexec [WINDOWMANAGER [ARGS ...]]
           Executes the WINDOWMANAGER with its ARGS. This is useful to switch the window manager
           in the running session without restarting the session. If no or an invalid
           WINDOWMANAGER is given, then herbstluftwm is restarted. For details see man 3 execvp.
           Example:

           •   wmexec openbox

       chain SEPARATOR [COMMANDS ...]
           chain expects a SEPARATOR and a list of COMMANDS with arguments. The commands have to
           be separated by the specified SEPARATOR. The SEPARATOR can by any word and only is
           recognized as the separator between commands if it exactly matches SEPARATOR. "chain"
           outputs the appended outputs of all commands and returns the exit code of the last
           executed command. Examples are:

           •   Create a tag called "foo" and directly use it:

               chain , add foo , use foo

           •   Rotate the layout clockwise:

               chain .-. lock .-. rotate .-. rotate .-. rotate .-. unlock

           Counterexamples are:

           •   This will only create a tag called "foo,":

               chain , add foo, use foo

           •   Separator "." defined, but "," is used:

               chain . add foo , use foo

       and SEPARATOR [COMMANDS ...]
           "and" behaves like the chain command but only executes the specified COMMANDS while
           the commands return the exit code 0.

       or SEPARATOR [COMMANDS ...]
           "or" behaves like the chain command but only executes the specified COMMANDS until one
           command returns the exit code 0.

       ! COMMAND
           "!" executes the provided command, but inverts its return value. If the provided
           command returns a nonzero, "!" returns a 0, if the command returns a zero, "!" returns
           a 1.

       try COMMAND
           "try" executes the provided command, prints its output, but always returns success,
           i.e. 0.

       silent COMMAND
           "silent" executes the provided command, but discards its output and only returns its
           exit code.

       focus_nth INDEX
           Focuses the nth window in a frame. The first window has INDEX 0. If INDEX is negative
           or greater than the last window index, then the last window is focused.

       cycle [DELTA]
           Cycles the selection within the current frame by DELTA or cycles through the clients
           in the floating layer if that is focused. If DELTA is omitted, DELTA = 1 will be used.
           DELTA can be negative; DELTA = -1 means: cycle in the opposite direction by 1.

       cycle_all [--skip-invisible] [DIRECTION]
           Cycles through all non-minimized windows and frames on the current tag.  DIRECTION = 1
           means forward (default value), DIRECTION = -1 means backward, DIRECTION = 0 has no
           effect. If there are multiple windows within one frame, then it acts similar to the
           cycle command. If --skip-invisible is given, then this only cycles through all visible
           windows and skips invisible windows in the max layout (the flag only affects invisible
           windows in the max layout; minimized windows are always skipped). After each focus
           change, the focused window is raised.

       cycle_frame [DIRECTION]
           Cycles through all frames on the current tag.  DIRECTION = 1 means forward, DIRECTION
           = -1 means backward, DIRECTION = 0 has no effect.  DIRECTION defaults to 1.

       cycle_layout [DELTA [LAYOUTS ...]]
           Cycles the layout algorithm in the current frame by DELTA.  DELTA defaults to 1. You
           can find a list of layout algorithms above. If a list of LAYOUTS is given,
           cycle_layout will cycle through those instead of the default layout algorithm list.
           This is done by finding the first occurrence of the current layout in LAYOUTS and
           picking the next layout according to DELTA. If the current layout doesn’t occur in
           LAYOUTS, the first entry is picked. Example:

           •   cycle_layout -1

           •   cycle_layout 1 vertical grid

       set_layout LAYOUT
           Sets the layout algorithm in the current frame to LAYOUT. For the list of layouts,
           check the list of layout algorithms above.

       close WINID
           Closes the specified window gracefully or the focused window if none is given
           explicitly. See the section on WINDOW IDS how to reference a certain window.

       close_or_remove
           Closes the focused window or removes the current frame if no window is focused. In
           floating mode, this acts as the close command.

       close_and_remove
           Closes the focused window and removes the current frame if no other window is present
           in that frame. In floating mode, this acts as the close command.

       split ALIGN [FRACTION [FRAMEINDEX]]
           Splits the focused frame (or the frame specified by FRAMEINDEX, see the section frame
           index) into two subframes with a specified FRACTION between 0 and 1 which defaults to
           0.5.  ALIGN is one of

           •   topbottom (= vertical)

           •   leftright (= horizontal)

           •   explodeauto (split along longest side)

               It specifies which of the two halves will be empty after the split. The other half
               will be occupied by the currently focused frame. After splitting, the originally
               focused frame will stay focused. One special ALIGN mode is explode, which splits
               the frame in such a way that the window focus, window sizes, and positions are
               kept as much as possible (so the default FRACTION is not always 0.5, unlike for
               the other ALIGN modes). Example:

           •   split explode

           •   split bottom 0.5

           •   split horiz 0.3

           •   split vertical 0.5

           •   split h

           •   split top 0.2 '' (splits the root frame)

       focus [-i|-e|--level=LEVEL] DIRECTION
           Moves the focus from current frame to the next frame or client in DIRECTION which is
           in:

           •   l[eft]

           •   r[ight]

           •   u[p]

           •   d[own]

           If there is no client within this frame or LEVEL is frame, then the next frame in
           specified DIRECTION will be focused. If LEVEL is visible or
           default_direction_external_only is unset, then the next client in DIRECTION can also
           be within the same frame, but has to be visible. For tabs LEVEL, the next client may
           be hidden in a tabbed_max layout. With all any client within a max layout maybe
           selected before focusing the next frame. The flag -i is an alias for --level=visible
           and -e for --level=frame.

           The direction between frames is defined as follows: The focus is in a leaf of the
           binary tree. Each inner node in the tree remembers the last focus direction (child 0
           or child 1). The algorithm uses the shortest possible way from the leaf (the currently
           focused frame) to the root until it is possible to change focus in the specified
           DIRECTION. From there the focus goes back to the leaf.

           Example: The focus is at frame A. After executing focus right focus will be at frame
           C.

                Tree:  H,0     Screen: ┌─────┐┌─────┐ (before)
                       ╱ ╲             │  B  ││  C  │
                      ╱   ╲            └─────┘└─────┘
                    V,1   V,0          ┌─────┐┌─────┐
                    ╱ ╲   ╱ ╲          │  A* ││  D  │
                   B  A* C   D         └─────┘└─────┘

                Tree:  H,1     Screen: ┌─────┐┌─────┐ (after focus right)
                       ╱ ╲             │  B  ││  C* │
                      ╱   ╲            └─────┘└─────┘
                    V,1   V,0          ┌─────┐┌─────┐
                    ╱ ╲   ╱ ╲          │  A  ││  D  │
                   B   A C*  D         └─────┘└─────┘

           If the currently focused client is floated, then the next floating window in the
           specified direction is focused and raised.

           If focus_crosses_monitor_boundaries is set and no client or frame is found in the
           specified DIRECTION, then the next monitor in that DIRECTION is focused.

       focus_edge [-i|-e] DIRECTION
           Focuses the window on the edge of the tag in the specified DIRECTION. The DIRECTIONS
           and -e behave as specified at the focus command.

           If -i (internal) is given or default_direction_external_only is unset, then the window
           on the edge of the tag will be focused. Else, only the frame on the edge of the tag
           will be focused, and the window that was last focused in that frame will be focused.

       raise WINID
           Raises the specified managed or unmanaged window. Managed windows are only moved
           within the tag’s stack (as reported by the stack command), and unmanaged windows are
           raised globally, i.e. are raised above all managed windows. See the section on WINDOW
           IDS on how to reference a certain window. Its result is only visible for floating
           windows and unmanaged windows.

       lower WINID
           Lowers the specified managed or unmanaged window, analogously to the raise command:
           managed windows are lowered within the stack of floating windows (with no effect for
           tiled windows) and unmanaged windows are moved below all managed windows (for example,
           it can be used to lower desktop windows).

       jumpto WINID
           Puts the focus to the specified window. See the section on WINDOW IDS on how to
           reference a certain window.

       bring WINID
           Moves the specified window to the current frame and focuses it. Floating windows are
           brought to the current tag, but keep their floating state. See the section on WINDOW
           IDS on how to reference a certain window.

       resize DIRECTION [FRACTIONDELTA]
           Changes the size of the focused frame in the specified DIRECTION by FRACTIONDELTA
           (which defaults to 0.02 if none is supplied).  DIRECTION behaves as specified at the
           focus command. If a floating window is focused, it grows towards next edge, i.e.
           either the edge of the next window or the monitor edge in the specified DIRECTION
           (FRACTIONDELTA is ignored in that case). Example:

           •   resize right +0.05

           •   resize down -0.1

       shift_edge [-i|-e] DIRECTION
           Shifts the focused window to the the edge of a tag in the specified DIRECTION. The
           DIRECTIONS behave as specified at the focus command and -i and -e behave as specified
           at the focus_edge command.

       shift [-i|-e] DIRECTION
           Shifts the focused window to the next frame in the specified DIRECTION. The DIRECTIONS
           and -i|-e behave as specified at the focus command. If the focused client is floated
           instead of being tiled, then client is shifted to the next window or screen edge. If
           the window cannot be moved and the setting focus_crosses_monitor_boundaries is
           activated, then the window is moved to the monitor in the specified DIRECTION.

       shift_to_monitor MONITOR
           Moves the focused window to the tag on the specified MONITOR. See the MONITORS
           section, how to address a monitor.

       remove
           Removes focused frame and merges its windows to its closest neighbour frame.

       rotate
           Rotates the layout on the focused tag counterclockwise by 90 degrees. This only
           manipulates the alignment of frames, not the content of them.

       mirror [vertical|horizontal|both]
           Mirrors the layout on the focused tag vertically, horizontally, or both; the default
           is horizontal. This command only manipulates the alignment of frames, not the content
           of them.

       set NAME VALUE
           Sets the specified setting NAME to VALUE. Allowed values for boolean settings are on
           or true for on, off or false for off, toggle to toggle its value. All settings are
           listed in the section below.

       get NAME
           Prints the value of setting NAME. All settings are listed in the section below.

       toggle NAME
           Toggles the setting NAME if it’s a boolean setting.

       cycle_value PATH VALUES ...
           Cycles value of the attribute PATH through VALUES: I.e. it searches the first
           occurrence of the current value in VALUES and changes the value to the next in the
           list or to the first one if the end is reached or current value wasn’t found. For
           compatibility reasons, PATH can also be the name of a setting. Examples:

           •   cycle_value settings.frame_gap 0 5 10 15

           •   cycle_value theme.active.inner_color red green blue

           •   the command cycle_layout +1 is equivalent to cycle_value
               tags.focus.tiling.focused_frame.algorithm

       cycle_monitor [DELTA]
           Cycles monitor focused by DELTA.  DELTA defaults to 1.

       focus_monitor MONITOR
           Puts focus to the specified monitor. See the MONITORS section, how to address a
           monitor.

       add TAG
           Creates a new empty tag named TAG.

       use TAG
           Switches the focused monitor to specified TAG.

       use_index INDEX [--skip-visible]
           Switches the focused monitor to the TAG with the specified INDEX. If INDEX starts with
           + or -, then INDEX is treated relative to the current TAG. If --skip-visible is passed
           and INDEX is relative, then tags that are already visible on a monitor are skipped.
           E.g. this cycles backwards through the tags:

           •   use_index -1 --skip-visible

       use_previous
           Switches the focused monitor to the previously viewed tag.

       merge_tag TAG [TARGET]
           Removes tag named TAG and moves all its windows to tag TARGET. If TARGET is omitted,
           the focused tag will be used.

       rename OLDTAG NEWTAG
           Renames tag named OLDTAG to NEWTAG.

       move TAG
           Moves the focused window to the tag named TAG.

       move_index INDEX [--skip-visible]
           Moves the focused window to the tag specified by INDEX. Analogical to the argument for
           use_index: If INDEX starts with + or -, then it is treated relative. If --skip-visible
           is passed with a relative index, then already visible tags are skipped.

       lock_tag [MONITOR]
           Lock the tag switching on the specified monitor. If no argument is given, the
           currently focused monitor is used. When the tag switching is disabled for a monitor,
           the commands use and use_index have no effect when executed there. When
           swap_monitors_to_get_tag is enabled, switching to a tag which is located on a locked
           monitor, switches to that monitor instead of stealing it from there. The lock state of
           a monitor is indicated by "[LOCKED]" in the list_monitors output.

       unlock_tag [MONITOR]
           Re-enables the tag switching on the specified monitor. If no argument is given, the
           currently focused monitor is used. This is the reverse operation to lock_tag and has
           no further side effects but removing this lock.

       disjoin_rects RECTS ...
           Takes a list of rectangles and splits them into smaller pieces until all rectangles
           are disjoint, the result rectangles are printed line by line. This command does not
           modify the current list of monitors! So this can be useful in combination with the
           set_monitors command.

           •   E.g.  disjoin_rects 600x400+0+0 600x400+300+250 prints this:

                   300x150+300+250
                   600x250+0+0
                   300x150+0+250
                   300x150+600+250
                   600x250+300+400

           •   In the above example two monitors are split into 5 monitors, which graphically
               means:

                   ┌──────┐                  ┌──────┐
                   │      │                  └──────┘
                   │  ┌───┼───┐              ┌─┐┌───┐┌──┐
                   │  │   │   │   disjoin    │ ││   ││  │
                   └──┼───┘   │  ─────────>  └─┘└───┘└──┘
                      │       │                 ┌───────┐
                      └───────┘                 └───────┘

       set_monitors RECTS ...
           Sets the list of monitors exactly to the list of given rectangles:

           •   The i’th existing monitor is moved to the i’th given RECT

           •   New monitors are created if there are more RECTS than monitors

           •   Existing monitors are deleted if there are more monitors than RECTS

       detect_monitors -l|--list|--list-all|--no-disjoin
           Sets the list of monitors to the physically available monitors. If both Xinerama and
           xrandr are missing, it will fall back to one monitor across the entire screen. If the
           detected monitors overlap, the will be split into more monitors that are disjoint but
           cover the same area using disjoin_rects.

           If -l or --list is passed, the list of rectangles of detected physical monitors is
           printed. So hc detect_monitors is equivalent to the bash command hc set_monitors $(hc
           disjoin_rects $(hc detect_monitors -l)).

           If --list-all is passed, then it is printed which multimonitor detection (xinerama,
           xrandr) has which set of physical monitors.

       add_monitor RECT [TAG [NAME]]
           Adds a monitor on the specified rectangle RECT and displays TAG on it.  TAG currently
           must not be displayed on any other monitor.  RECT is a string of the form WxH±X±Y. If
           no or an empty TAG is given, then any free tag will be chosen. If a NAME is given, you
           can reference to this monitor by its name instead of using an index. Example:

           •   add_monitor 1024x768-20+0 mynewtag main

       remove_monitor MONITOR
           Removes the specified monitor.

       move_monitor MONITOR RECT [PADUP [PADRIGHT [PADDOWN [PADLEFT]]]]
           Moves the specified monitor to rectangle RECT.  RECT is defined as in add_monitor. If
           no or an empty pad is given, it is not changed.

       raise_monitor [MONITOR]
           Raises the specified monitor or the current one if MONITOR is omitted.

       rename_monitor MONITOR NAME
           (Re)names an already existing monitor. If NAME is empty, it removes the monitor’s
           name.

       stack
           Prints the stack of monitors with the visible tags and their layers as a tree. The
           order of the printed stack is top to bottom. The style is configured by the tree_style
           setting.

       monitor_rect [[-p] MONITOR]
           Prints the rectangle of the specified monitor in the format: X Y W H If no MONITOR or
           cur is given, then the current monitor is used. If -p is supplied, then the remaining
           rect without the pad around this monitor is printed.

       pad MONITOR [PADUP [PADRIGHT [PADDOWN [PADLEFT]]]]
           Sets the pad of specified monitor to the specified padding. If no or an empty padding
           is given, it is not changed.

       list_padding [MONITOR]
           Lists the padding of the specified monitor, or the currently focused monitor if no
           monitor is given.

       layout [TAG [INDEX]]
           Prints the layout of frame with INDEX on TAG, in a nice tree style. Its style is
           defined by the tree_style setting. If no TAG is given, the current tag is used. If no
           INDEX is given, the root frame is used. To specify INDEX without specifying TAG (i.e.
           use current tag), pass an empty string as TAG.

           An example output is:

               ╾─┐ horizontal 50% selection=1
                 ├─╼ vertical: 0xe00009
                 └─┐ vertical 50% selection=0
                   ├─╼ vertical: 0xa00009 [FOCUS]
                   └─╼ vertical: 0x1000009

       dump [TAG [INDEX]]
           Prints the same information as the layout command but in a machine readable format.
           Its output can be read back with the load command.

           An example output (formatted afterwards) is:

               (split horizontal:0.500000:1
                   (clients vertical:0 0xe00009)
                   (split vertical:0.500000:1
                       (clients vertical:0 0xa00009)
                       (clients vertical:0 0x1000009)))

       load [TAG] LAYOUT
           Loads a given LAYOUT description to specified TAG or current tag if no TAG is given.

           Caution
           LAYOUT is exactly one parameter. If you are calling it manually from your shell or
           from a script, quote it properly!

       complete POSITION [COMMAND ARGS ...]
           Prints the result of tab completion for the partial COMMAND with optional ARGS. You
           usually do not need this, because there is already tab completion for bash, zsh and
           fish. Example:

           •   complete 0 m

               prints all commands beginning with m

           •   complete 1 toggle fra

               prints all settings beginning with fra that can be toggled

       complete_shell POSITION [COMMAND ARGS ...]
           Behaves like complete with the following extras, useful for completion on posix
           shells:

           •   Escape sequences are removed in COMMAND and ARGS.

           •   A space is appended to each full completion result.

           •   Special characters will be escaped in the output.

       emit_hook NAME ARGS ...
           Emits a custom hook NAME to all idling herbstclients.

       tag_status [MONITOR]
           Print a tab separated list of all tags for the specified MONITOR index. If no MONITOR
           index is given, the focused monitor is used. Each tag name is prefixed with one char,
           which indicates its state:

           •   .  the tag is empty

           •   : the tag is not empty

           •   + the tag is viewed on the specified MONITOR, but this monitor is not focused.

           •   # the tag is viewed on the specified MONITOR and it is focused.

           •   - the tag is viewed on a different MONITOR, but this monitor is not focused.

           •   % the tag is viewed on a different MONITOR and it is focused.

           •   !  the tag contains an urgent window

           Warning
           If you use a tab in one of the tag names, then tag_status is probably quite useless
           for you.

       floating [[TAG] on|off|toggle|status]
           Changes specified TAG to floating/tiling mode or prints its current status. If no TAG
           is given, the current tag is used. If no argument is given, floating mode is toggled.
           If status is given, then on or off is printed, depending of the floating state of TAG.

       rule [[--]FLAG|[--]LABEL|[--]CONDITION|[--]CONSEQUENCE ...]
           Defines a rule which will be applied to all new clients. Its behaviour is described in
           the RULES section.

       unrule LABEL|--all|-F
           Removes all rules named LABEL. If --all or -F is passed, then all rules are removed.

       apply_rules WINID|--all
           Apply the rules to the specified window WINID. If --all is passed, then the rules are
           applied to all clients.

       apply_tmp_rule WINID|--all [RULEDESCRIPTION...]
           Apply the rule RULEDESCRIPTION to one particular client WINID or all clients (--all)
           without adding the rule to the rule list. The RULEDESCRIPTION specifies a rule
           consisting of conditions and consequences as one would pass it to the rule command as
           described in the RULES section. This allows testing rules before adding them. Running
           apply_tmp_rule only applies the particular rule given in the arguments and ignores the
           existing rules.

       fullscreen [on|off|toggle]
           Sets or toggles the fullscreen state of the focused client. If no argument is given,
           fullscreen mode is toggled.

       pseudotile [on|off|toggle]
           Sets or toggles the pseudotile state of the focused client. If a client is
           pseudotiled, then in tiling mode the client is only moved but not resized - the client
           size will stay the floating size. The only reason to resize the client is to ensure
           that it fits into its tile. If no argument is given, pseudotile mode is toggled.

       object_tree [PATH]
           Prints the tree of objects. If the object path PATH is given, only the subtree
           starting at PATH is printed. See the OBJECTS section for more details.

       attr [PATH [NEWVALUE]
           Prints the children and attributes of the given object addressed by PATH. If PATH is
           an attribute, then print the attribute value. If NEWVALUE is given, assign NEWVALUE to
           the attribute given by PATH. See the OBJECTS section for more details.

       get_attr ATTRIBUTE
           Print the value of the specified ATTRIBUTE as described in the OBJECTS section.

       set_attr ATTRIBUTE NEWVALUE
           Assign NEWVALUE to the specified ATTRIBUTE as described in the OBJECTS section.

       attr_type ATTRIBUTE
           Print the type of the specified ATTRIBUTE.

       new_attr bool|color|int|string|uint PATH [VALUE]
           Creates a new attribute with the name and in the object specified by PATH. Its type is
           specified by the first argument. The attribute name has to begin with my_. If VALUE is
           supplied, then it is written to the attribute (if this fails the attribute still
           remains).

       watch PATH
           Watch the value of the given attribute PATH. Whenever the value changes from OLDVALUE
           to NEWVALUE, a hook is emitted:

           attribute_changed PATH OLDVALUE NEWVALUE

       remove_attr PATH
           Removes the user defined attribute PATH.

       substitute IDENTIFIER ATTRIBUTE COMMAND [ARGS ...]
           Replaces all exact occurrences of IDENTIFIER in COMMAND and its ARGS by the value of
           the ATTRIBUTE. Note that the COMMAND also is replaced by the attribute value if it
           equals IDENTIFIER. The replaced command with its arguments then is executed. Example:

           •   substitute MYTITLE clients.focus.title echo MYTITLE

               Prints the title of the currently focused window.

       sprintf IDENTIFIER FORMAT [FORMATARG ...] COMMAND [CMDARGS ...]
           Replaces all exact occurrences of IDENTIFIER in COMMAND and its CMDARGS by the string
           specified by FORMAT. The FORMAT string may contain several placeholders, similar to
           the printf(1) command:

           •   %s inserts an attribute value whose path is given by the string value of the next
               FORMATARG%c ("constant") inserts the next FORMATARG without modification.

           •   %{ATTR} inserts the current value of the attribute ATTR. The path ATTR can itself
               contain format placeholders. This can be used to compose attribute paths at run
               time, e.g. in a foreach loop.

           •   %% stands for a plain %

           The replaced command with its arguments then is executed. Examples:

           •   sprintf STR title=%s clients.focus.title echo STR

               Prints the title of the currently focused window prepended by title=.

           •   sprintf X "%c %s tags" "there are" tags.count echo X

               Prints there are N tags with N replaced by the number of tags.

           •   sprintf X tag=%s tags.focus.name rule once X

               Moves the next client that appears to the tag that is currently focused.

           •   sprintf X %s/%s tags.focus.index tags.count echo X

               Tells which tag is focused and how many tags there are

           •   sprintf l somelongstring echo l l l

               Prints somelongstring three times, separated by spaces.

           •   sprintf VALUE "%{%c.client_count}" tags.0 echo VALUE

               Prints the number of clients on the tag with index 0

           •   foreach --filter-name="[0-9]*" T tags. sprintf S "%{%c.client_count}" T echo T S

               Prints the number of clients for each tag.

           •   substitute X tags.count sprintf Y "number=%c" X echo Y

               has the same output as

               sprintf Y "number=%s" tags.count echo Y

               (Note how the %c changes to %s)

       foreach IDENTIFIER OBJECT [--recursive] [--unique] [--filter-name=REGEX] COMMAND [ARGS
       ...]
           For each child of the given OBJECT the COMMAND is called with its ARGS, where the
           IDENTIFIER is replaced by the path of the child. The options are:

           •   --filter-name=REGEX consider children whose name match the specified REGEX.

           •   --unique do not print duplicates (some objects can be reached via multiple paths,
               such as clients.focus)

           •   --recursive print OBJECT and all its children of arbitrary depth in breadth-first
               search order. This implicitly activates --unique.

           The exit code is the exit code of the command executed last. Examples:

           •   foreach T tags.by-name. echo T

               Prints:

                   tags.by-name.1
                   tags.by-name.2
                   tags.by-name.3
                   [...]

           •   Note that foreach only iterates over children, but not over attributes, so foreach
               S settings echo S prints nothing, since the settings object has only attributes
               but no child objects.

           •   foreach C clients. echo C prints the object paths of all clients, but the focused
               client twice, because it is mentioned in clients.  twice: by window id and as
               clients.focus.

           •   foreach F tags.focus.tiling.root. --recursive echo F prints the object paths of
               all frames on the focused tag.

       mktemp [bool|int|string|uint] IDENTIFIER COMMAND [ARGS ...]
           Creates a temporary attribute with the given type and replaces all occurrences of
           IDENTIFIER in COMMAND and ARGS by the path of the temporary attribute. The replaced
           command with its arguments is executed then. The exit status of COMMAND is returned.

       compare ATTRIBUTE OPERATOR VALUE
           Compares the value of ATTRIBUTE with VALUE using the comparison method OPERATOR. If
           the comparison succeeds, it returns 0, else 1. The operators are:

           •   =: ATTRIBUTE's value equals VALUE!=: ATTRIBUTE's value does not equal VALUEle: ATTRIBUTE's value <= VALUElt: ATTRIBUTE's value < VALUEge: ATTRIBUTE's value >= VALUEgt: ATTRIBUTE's value > VALUE

           The OPERATORs le,lt,ge,gt can only be used if ATTRIBUTE is of the type integer or
           unsigned integer. Note that the first parameter must always be an attribute and the
           second a constant value. If you want to compare two attributes, use the substitute
           command:

               substitute FC tags.focus.frame_count \
                   compare tags.focus.client_count gt FC

           It returns success if there are more clients on the focused tag than frames.

       getenv NAME
           Gets the value of the environment variable NAME.

       setenv NAME VALUE
           Set the value of the environment variable NAME to VALUE. See the export command for a
           convenience wrapper.

       unsetenv NAME
           Unsets the environment variable NAME.

       export NAME=VALUE
           Set the value of the environment variable NAME to VALUE. The syntax is the same as for
           export in unix shells (notice that there is a =). Intuitively, if you forgot to run
           export FOO=BAR before starting herbstluftwm, you can run herbstclient export FOO=BAR
           from within your herbstluftwm session for the same effect. The export command is the
           same as the setenv command with different syntax.

RULES

       Rules are used to change default properties for certain clients when they appear or when
       the apply_rules command is called. Each rule matches against a certain subset of all
       clients and defines a set of properties for them (called CONSEQUENCEs). A rule can be
       defined with this command:

       rule [[--]FLAG|[--]LABEL|[--]CONDITION|[--]CONSEQUENCE ...]

       Each rule consists of a list of FLAGs, CONDITIONs, CONSEQUENCEs and, optionally, a LABEL.
       (each of them can be optionally prefixed with two dashes (--) to provide a more
       iptables(8)-like feeling).

       Each rule can be given a custom label by specifying the LABEL property:

       •   [--]label=VALUE

       If multiple labels are specified, the last one in the list will be applied. If no label is
       given, then the rule will be given an integer name that represents the index of the rule
       since the last unrule -F command (which is triggered in the default autostart).

           Tip
           Rule labels default to an incremental index. These default labels are unique, unless
           you assign a different rule a custom integer LABEL. Default labels can be captured
           with the printlabel flag.

       If a new client appears, herbstluftwm tries to apply each rule to this new client as
       follows: If each CONDITION of this rule matches against this client, then every
       CONSEQUENCE is executed. (If there are no conditions given, then this rule is executed for
       each client)

       Each CONDITION consists of a property name, an operator and a value. Valid operators are:

       •   ~ matches if client’s property is matched by the regex value.

       •   = matches if client’s property string is equal to value.

       Valid properties are:

       instance
           the first entry in client’s WM_CLASS.

       class
           the second entry in client’s WM_CLASS.

       title
           client’s window title.

       pid
           the client’s process id (Warning: the pid is not available for every client. This only
           matches if the client sets _NET_WM_PID to the pid itself).

       pgid
           this client’s process group id. Since the pgid of a window is derived from its pid the
           same restrictions apply as above.

       maxage
           matches if the age of the rule measured in seconds does not exceed value. This
           condition only can be used with the = operator. If maxage already is exceeded (and
           never will match again), then this rule is removed. (With this you can build rules
           that only live for a certain time.)

       windowtype
           matches the _NET_WM_WINDOW_TYPE property of a window. If _NET_WM_WINDOW_TYPE has
           multiple entries, then only the first entry is used here.

       windowrole
           matches the WM_WINDOW_ROLE property of a window if it is set by the window.

       fixedsize (no parameter)
           matches if the window does not allow being resized (i.e. if the minimum size matches
           the maximum size). This condition does not take a parameter. Example:

               hc rule fixedsize floating=on

       Each CONSEQUENCE consists of a NAME=VALUE pair. Valid NAMES are:

       tag
           moves the client to tag VALUE.

       monitor
           moves the client to the tag on monitor VALUE. If the tag consequence was also
           specified, and switchtag is set for the client, move the client to that tag, then
           display that tag on monitor VALUE. If the tag consequence was specified, but switchtag
           was not, ignore this consequence.

       focus
           decides whether the client gets the input focus in its tag. The default is off.  VALUE
           is a boolean (on or off).

       switchtag
           if focus is activated and the client is put to a not focused tag, then switchtag tells
           whether the client’s tag will be shown or not. If the tag is shown on any monitor but
           is not focused, the client’s tag only is brought to the current monitor if
           swap_monitors_to_get_tag is activated.  VALUE is a boolean (on or off).

       manage
           decides whether the client will be managed or not. The default is on.  VALUE is a
           boolean (on or off).

       index
           moves the window to a specified index in the tree.  VALUE is a frame index.

       floating
           sets the floating state of the client.  VALUE is a boolean.

       pseudotile
           sets the pseudotile state of the client.  VALUE is a boolean.

       ewmhrequests
           sets whether the window state (the fullscreen state and the demands attention flag)
           can be changed by the application via ewmh itself. This does not affect the initial
           fullscreen state requested by the window.  VALUE is a boolean; it defaults to on.

       ewmhnotify
           sets whether hlwm should let the client know about EMWH changes (currently only the
           fullscreen state). If this is set, applications do not change to their fullscreen-mode
           while still being fullscreen.  VALUE is a boolean, it defaults to on.

       fullscreen
           sets the fullscreen flag of the client.  VALUE is a boolean.

       hook
           emits the custom hook rule VALUE WINID when this rule is triggered by a new window
           with the id WINID. This consequence can be used multiple times, which will cause a
           hook to be emitted for each occurrence of a hook consequence.

       keymask
           sets the keymask for a client (see the keymask attribute documentation).

       keys_inactive
           sets a regex that determines which key bindings are inactive for a client (see the
           keys_inactive attribute documentation).

       floatplacement
           changes the floating position of a window. The VALUE can be one of the following:

           •   none does not change the placement at all

           •   center centers the window on the monitor

           •   smart tries to place it with as little overlap to other floating windows as
               possible. If there are multiple options with the least overlap, then the position
               with the least overlap to tiling windows is chosen.

       floating_geometry
           Sets the client’s floating_geometry attribute. The VALUE is a rectangle, interpreted
           relatively to the monitor. If floatplacement is also specified for the client
           (possibly by another rule), then only the size of the floating_geometry is used. In
           order to force the position from the geometry, it is necessary to add
           floatplacement=none.

       A rule’s behaviour can be configured by some special FLAGS:

       •   not: negates the next CONDITION.

       •   !: same as not.

       •   once: only apply this rule once (and delete it afterwards).

       •   printlabel: prints the label of the newly created rule to stdout.

       •   prepend: prepend the rule to the list of rules instead of appending it. So its
           consequences may be overwritten by already existing rules.

       Examples:

       •   rule --class=Netscape --tag=6 --focus=off

           Moves all Netscape instances to tag 6, but doesn’t give focus to them.

       •   rule not class~.*[Tt]erm tag=2

           Moves all clients to tag 2, if their class does not end with term or Term.

       •   rule class=Thunderbird index=/0

           Insert all Thunderbird instances in the tree that has no focus and there in the first
           child.

       •   rule --windowtype=_NET_WM_WINDOW_TYPE_DIALOG --focus=on

           Sets focus to new dialogs which set their _NET_WM_WINDOW_TYPE correctly.

WINDOW IDS

       Several commands accept a window as reference, e.g. close. The syntax is as follows:

       •   an empty string — or missing argument — references the currently focused window.

       •   urgent references some window that is urgent.

       •   0xHEXID — where HEXID is some hexadecimal number — references the window with
           hexadecimal X11 window id HEXID.

       •   longest-minimized references the minimized window on the focused tag that has been
           minimized for the longest time.

       •   latest-minimized references the minimized window on the focused tag that has been
           minimized most recently.

       •   DECID — where DECID is some decimal number — references the window with the decimal
           X11 window id DECID.

OBJECTS

       The object tree is a collection of objects with attributes similar to /sys known from the
       Linux kernel. Many entities (like tags, monitors, clients, ...) have objects to access
       their attributes directly. The tree is printed by the object_tree command and looks more
       or less as follows:

           $ herbstclient object_tree
           ╾─┐
             ├─┐ tags
             │ ├─┐ by-name
             │ │ ├─╼ 1
             │ │ ...
             │ │ └─╼ 9
             │ └─╼ focus
             ├─┐ clients
             │ ├─╼ 0x1400022
             │ └─╼ focus
             └─┐ monitors
               ├─╼ by-name
               └─╼ focus

       To print a subtree starting at a certain object, pass the PATH of the object to
       object_tree. The object PATH is the path using the separator . (dot), e.g. tags.by-name:

           $ herbstclient object_tree tags.by-name.
           ╾─┐ tags.by-name.
             ├─╼ 1
             ├─╼ 2
             ...
             └─╼ 9

       To query all attributes and children of a object, pass its PATH to attr:

           $ herbstclient attr tags.
           2 children:
             by-name.
             focus.

           1 attributes:
            .---- type
            | .-- writable
            V V
            u - count                = 9

           $ herbstclient attr tags.focus.
           0 children.
           6 attributes:
            .---- type
            | .-- writable
            V V
            s w name                 = "1"
            b w floating             = false
            i - frame_count          = 2
            i - client_count         = 1
            i - curframe_windex      = 0
            i - curframe_wcount      = 1

       This already gives an intuition of the output: attr first lists the names of the child
       objects and then all attributes, telling for each attribute:

       •   its type

           •   b for boolean

           •   c for color

           •   i for integer

           •   r for regex

           •   s for string

           •   u for unsigned integer

       •   if it is writable by the user: w if yes, - else.

       •   the name of the attribute

       •   its current value (only quoted for strings)

       To get the unquoted value of a certain attribute, address the attribute using the same
       syntax as for object paths and pass it to attr or get_attr:

           $ herbstclient attr clients.focus.title
           herbstluftwm.txt = (~/dev/c/herbstluftwm/doc) - VIM
           $ herbstclient get_attr  clients.focus.title
           herbstluftwm.txt = (~/dev/c/herbstluftwm/doc) - VIM

       To change a writable attribute value pass the new value to attr or to set_attr:

           $ herbstclient attr tags.focus.floating
           false
           $ herbstclient attr tags.focus.floating true
           $ herbstclient attr tags.focus.floating
           true
           $ herbstclient set_attr tags.focus.floating false
           $ herbstclient attr tags.focus.floating
           false

       More information on an attribute or object is given by the help command:

           $ herbstclient help clients.focus

       Just look around to get a feeling what is there. The entry point is a root object that has
       the following child objects:

   autostart:string global_path = globalAutostart: Path of the system-wide autostart, used as a
           fallback.

       •   int last_status = 0: the exit status of the last autostart run. if the autostart is
           still running, then this status corresponds to the exit status of the previous
           autostart invocation.

       •   string path = autostartFromCmdLine: Custom path to the user’s autostart path. If it is
           empty, then the autostart in $XDG_CONFIG_HOME or $HOME is used.

       •   uint pid = 0: the process id of the last autostart invocation. Even if the autostart
           is not running anymore, its pid is still present here.

       •   bool running = false: whether the autostart process (with pid) is still running.

   clients:
       The managed windows. For every (managed) window id there is an entry here.

       •   dragged: the object of a client which is currently dragged by the mouse, if any. See
           the documentation of the mousebind command for examples. For attributes and children,
           see clients.focusfocus: the focused client (only exists if a client is focused).  a managed window

           •   string class: the class of it (second entry in WM_CLASS)

           •   Rectangle content_geometry: the geometry of the application content, that is, not
               taking the decoration into account. Also, this is the last window geometry that
               was reported to the client application.

           •   bool decorated = true: whether window border and title are drawn

           •   Rectangle decoration_geometry: the geometry of the client, taking the window
               decoration into account. The position is the global window position, that is,
               relative to the top left corner of the entire screen

           •   bool ewmhnotify = true: if the client is told about its state via ewmh

           •   bool ewmhrequests = true: if ewmh requests are permitted for this client

           •   bool floating = false: whether this client is set as a (single-window) floating
               client. If set, the client is floated above the tiled clients.

           •   bool floating_effectively = false: whether this client is in the floating state
               currently. This is the case if the client’s tag is set to floating mode or if the
               client itself is set as floating. Its value is also indicated via the X11
               properties HLWM_FLOATING_WINDOW and HLWM_TILING_WINDOW.

           •   Rectangle floating_geometry = 0: the geometry of the client content if the client
               is in floating mode. The position is relative to the monitor and does not take the
               window decoration into account.

           •   bool fullscreen = false: whether this client covers all other windows and panels
               on its monitor.

           •   string instance: the instance of it (first entry in WM_CLASS)

           •   regex keymask = "": A regular expression that is matched against the string
               representation of all key bindings (as they are printed by list_keybinds). While
               this client is focused, only bindings that match the expression will be active.
               Any other bindings will be disabled. The default keymask is an empty string (),
               which does not disable any keybinding.

           •   regex keys_inactive = "": A regular expression that describes which keybindings
               are inactive while the client is focused. If a key combination is pressed and its
               string representation (as given by list_keybinds) matches the regex, then the key
               press is propagated to the client.

           •   bool minimized = false: whether this client is minimized (also called iconified).

           •   int pgid = -1

           •   int pid = -1: the process id of it (-1 if unset).

           •   bool pseudotile = false: if activated, the client always has its floating window
               size, even if it is in tiling mode.

           •   bool sizehints_floating = true: if sizehints for this client should be respected
               in floating mode

           •   bool sizehints_tiling = false: if sizehints for this client should be respected in
               tiling mode

           •   string tag: the name of the tag it’s currently on.

           •   string title = "": its window title

           •   bool urgent = false: the urgency state (also known as: demands attention). The
               focused client can not be urgent.

           •   bool visible = visible_already: whether this client is rendered currently

           •   string winid = "": its window id (as a hexadecimal number with 0x prefix)

           •   parent_frame: the frame contaning this client if the client is tiled. For
               attributes and children, see tags.focus.tiling.root

   monitors:
       Every monitor is a rectangular part of the screen on which a tag is shown. These monitors
       may or may not match the actual outputs. This has an entry INDEX for each monitor with
       index INDEX.

       •   uint countby-name: This has an entry name for every object with the given name. If an object has
           an empty name then it is not listed here.

       •   focus: the focused monitor.  The monitor is a rectangular part on the screen that
           holds precisely one tag at a time. The pad attributes reserve space on the monitor’s
           edge for panels, so this space (given in number of pixels) is never occupied by tiled
           clients.

           •   Rectangle content_geometry: the inner geometry of the monitor, i.e. the geometry
               with the pads deducted from all sides. This is the area floating and tiled client
               windows are placed.

           •   Rectangle geometry = rect_: the outer geometry of the monitor

           •   uint index = 0: the monitor’s index (starts at index 0)

           •   bool lock_tag = false: if activated, then it it is not possible to switch this
               monitor to a different tag.

           •   string name = "": the monitor’s name (can be empty)

           •   int pad_down = 0: space for panels at the monitor’s lower edge

           •   int pad_left = 0: space for panels at the monitor’s left edge

           •   int pad_right = 0: space for panels at the monitor’s right edge

           •   int pad_up = 0: space for panels at the monitor’s upper edge

           •   string tag: the name of the tag viewed here

   panels:
       For every panel window, there is an entry with the panel’s window id here.

       •   uint count0xWindowID: a panel is an unmanaged window that reserves space at the edge of the
           monitor it is on. The space depends on the _NET_WM_STRUT defined by the panel. If it
           is however not defined explicitly, then the amount of reserved space is inferred from
           the window geometry.

           •   string class: the window class (second entry of WM_CLASS)

           •   Rectangle geometry: the size and position of the window

           •   string instance: the window instance (first entry of WM_CLASS)

           •   WindowID winid = winid: the ID of the panel window

   settings:
       Settings configure the general behaviour of herbstluftwm and can be controlled via the
       set, get and toggle commands. The settings. object has an attribute for each setting. Many
       settings are wrappers around attributes and only remain for compatibility.

       •   bool always_show_frame = false: DEPRECATED, use show_frame_decorations instead.
           Setting this corresponds to focused in show_frame_decorations.

       •   bool auto_detect_monitors = false: If set, detect_monitors is automatically executed
           every time a monitor is connected, disconnected or resized.

       •   bool auto_detect_panels = true: If set, EWMH panels are automatically detected and
           reserve space at the side of the monitors they are on (via pad attributes of each
           monitor). This setting is activated per default.

       •   bool default_direction_external_only = false: This setting controls the behaviour of
           focus and shift if no -e or -i argument is given. If set, then focus and shift changes
           the focused frame even if there are other clients in this frame in the specified
           DIRECTION. Else, a client within current frame is selected if it is in the specified
           DIRECTION.

       •   LayoutAlgorithm default_frame_layout = vertical: Name of the layout algorithm, which
           is used if a new frame is created (on a new tag or by a non-trivial split). See above
           for the list of layout algorithms.

       •   string ellipsis = ...: string to append when window or tab titles are shortened to fit
           in the available space.

       •   bool focus_crosses_monitor_boundaries = true: If set, commands focus and shift cross
           monitor boundaries. If there is no client in the direction given to focus, then the
           monitor in the specified direction is focused. Similarly, if shift cannot move a
           window within a tag, the window is moved to the neighbour monitor in the desired
           direction.

       •   bool focus_follows_mouse = false: If set and a window is focused by mouse cursor, this
           window is focused (this feature is also known as sloppy focus). If unset, you need to
           click to change the window focus by mouse.

           If another window is hidden by the focus change (e.g. when having pseudotiled windows
           in the max layout) then an extra click is required to change the focus.

       •   bool focus_stealing_prevention = true: If set, only pagers and taskbars are allowed to
           change the focus. If unset, all applications can request a focus change.

       •   int frame_active_opacity = 100: Focused frame opacity in percent. Requires a running
           compositing manager to take actual effect.

       •   color frame_bg_active_color = black: The fill color of a focused frame.

       •   color frame_bg_normal_color = black: The fill color of an unfocused frame (It is only
           visible if non-focused frames are configured to be visible, see
           show_frame_decorations).

       •   bool frame_bg_transparent = false: If set, the background of frames are transparent.
           That means a rectangle is cut out from the inner such that only the frame border and a
           stripe of width frame_transparent_width can be seen. Use frame_active_opacity and
           frame_normal_opacity for real transparency.

       •   color frame_border_active_color = red: The border color of a focused frame.

       •   color frame_border_inner_color = black: The color of the inner border of a frame.

       •   int frame_border_inner_width = 0: The width of the inner border of a frame. Must be
           less than frame_border_width, since it does not add to the frame border width but is a
           part of it.

       •   color frame_border_normal_color = blue: The border color of an unfocused frame.

       •   int frame_border_width = 2: Border width of a frame.

       •   int frame_gap = 5: The gap between frames in the tiling mode.

       •   int frame_normal_opacity = 100: Unfocused frame opacity in percent. Requires a running
           compositing manager to take actual effect.

       •   int frame_padding = 0: The padding within a frame in the tiling mode, i.e. the space
           between the border of a frame and the windows within it.

       •   int frame_transparent_width = 0: Specifies the width of the remaining frame colored
           with frame_bg_active_color if frame_bg_transparent is set.

       •   bool gapless_grid = true: This setting affects the size of the last client in a frame
           that is arranged by grid layout. If set, then the last client always fills the gap
           within this frame. If unset, then the last client has the same size as all other
           clients in this frame.

       •   bool hide_covered_windows = false: If activated, windows are explicitly hidden when
           they are covered by another window in a frame with max layout. This only has a visible
           effect if a compositor is used. If activated, shadows do not stack up and transparent
           windows show the wallpaper behind them instead of the other clients in the max layout.

       •   uint monitors_locked = 0: If greater than 0, then the clients on all monitors aren’t
           moved or resized anymore. If it is set to 0, then the arranging of monitors is enabled
           again, and all monitors are rearranged if their content has changed in the meantime.
           You should not change this setting manually due to concurrency issues; use the
           commands lock and unlock instead.

       •   int mouse_recenter_gap = 0: Specifies the gap around a monitor. If the monitor is
           selected and the mouse position would be restored into this gap, it is set to the
           center of the monitor. This is useful, when the monitor was left via mouse movement,
           but is reselected by keyboard. If the gap is 0 (default), the mouse is never
           recentered.

       •   int pseudotile_center_threshold = 10: If greater than 0, it specifies the least
           distance between a centered pseudotile window and the border of the frame or tile it
           is assigned to. If this distance is lower than pseudotile_center_threshold, it is
           aligned to the top left of the client’s tile.

       •   bool raise_on_click = true: If set, a window is raised if it is clicked. The value of
           this setting is only noticed in floating mode.

       •   bool raise_on_focus = false: If set, a window is raised if it is focused. The value of
           this setting is only used in floating mode.

       •   bool raise_on_focus_temporarily = false: If set, a window is raised temporarily if it
           is focused on its tag. Temporarily in this case means that the window will return to
           its previous stacking position if another window is focused.

       •   ShowFrameDecorations show_frame_decorations = focused_if_multiple: This controls,
           which frame decorations are shown at all.

           •   none shows no frame decorations at all,

           •   nonempty shows decorations of frames that have client windows,

           •   if_multiple shows decorations on the tags with at least two frames,

           •   if_empty shows decorations of frames that have no client windows,

           •   focused shows the decoration of focused and nonempty frames,

           •   focused_if_multiple shows decorations of focused and non-empty frames on tags with
               at least two frames.

       •   SmartFrameSurroundings smart_frame_surroundings = off: If set to hide_all, frame
           borders and gaps will be removed when there is no ambiguity regarding the focused
           frame. If set to hide_gaps, only frame gaps will be removed when there is no ambiguity
           regarding the focused frame. Turn off to always show frame borders and gaps.

       •   bool smart_window_surroundings = false: If set, window borders and gaps will be
           removed and minimal when there’s no ambiguity regarding the focused window. This
           minimal window decoration can be configured by the theme.minimal object.

       •   int snap_distance = 10: If a client is dragged in floating mode, then it snaps to
           neighbour clients if the distance between them is smaller than snap_distance.

       •   int snap_gap = 5: Specifies the remaining gap if a dragged client snaps to an edge in
           floating mode. If snap_gap is set to 0, no gap will remain.

       •   bool swap_monitors_to_get_tag = true: If set: If you want to view a tag, that already
           is viewed on another monitor, then the monitor contents will be swapped and you see
           the wanted tag on the focused monitor. If not set, the other monitor is focused if it
           shows the desired tag.

       •   bool tabbed_max = true: if activated, multiple windows in a frame with the max layout
           algorithm are drawn as tabs.

       •   string tree_style = "*| +`--.": It contains the chars that are used to print a nice
           ascii tree. It must contain at least 8 characters. e.g.  X|:#+*-.  produces a tree
           like:

               X-.
                 #-. child 0
                 | #-* child 00

                 +-. child 1
                 : #-* child 10
                 : +-* child 11

           Useful values for tree_style are: ╾│ ├└╼─┐ or -| |'--.  or ╾│ ├╰╼─╮.

       •   bool update_dragged_clients = false: If set, a client's window content is resized
           immediately during resizing it with the mouse. If unset, the client's content is
           resized after the mouse button is released.

       •   bool verbose = false: If set, verbose output is logged to herbstluftwm’s stderr. The
           default value is controlled by the --verbose command line flag.

       •   int window_border_inner_width: The width of the inner border of a window. Must be less
           than window_border_width, since it does not add to the window border width but is a
           part of it.

       Setting an attribute of the theme object just propagates the value to the respective
       attribute of the tiling and the floating object. If the title area is divided into tabs,
       then the not selected tabs can be styled using the tab_... attributes. If these attributes
       are empty, then the colors are taken from the theme of the client to which the tab refers
       to.

               non-urgent and unfocused tabs

           •   MaybeColor tab_title_color = Inherit: if non-empty, the title color of non-urgent
               and unfocused tabs

           •   bool tight_decoration = false: specifies whether the size hints also affect the
               window decoration or only the window contents of tiled clients (requires enabled
               sizehints_tiling)

           •   TextAlign title_align = left: the horizontal alignment of the title within the tab
               or title bar. The value is one of: left, center, right

           •   color title_color = black

           •   int title_depth = 0: the space below the baseline of the window title

           •   font title_font = fixed

           •   uint title_height = 0

           •   TitleWhen title_when = always: when to show the window title: always, never, if
               the the client is in a tabbed scenario like a max frame (one_tab), if there are
               multiple_tabs to be shown.

           •   active: configures the decoration of the focused client. For attributes and
               children, see theme.activenormal: the default decoration scheme for clients. For attributes and children,
               see theme.activeurgent: configures the decoration of urgent clients. For attributes and children,
               see theme.activefullscreen: configures clients in fullscreen state. For attributes and children, see
           theme.floatingminimal: configures clients with minimal decorations triggered by
           smart_window_surroundings. For attributes and children, see theme.floatingnormal: the default decoration scheme for clients. For attributes and children, see
           theme.activetiling: configures the decoration of tiled clients, setting one of its attributes
           propagates the respective attribute of the active, normal and urgent child objects.
           For attributes and children, see theme.floatingurgent: configures the decoration of urgent clients. For attributes and children, see
           theme.active

   types:
       This lists the types that are used for attributes and command arguments.

       •   bool: Type representing boolean values, i.e. an on or off state, with aliases true and
           false. When writing to a boolean value, one can also specify toggle in order to alter
           its value.

           •   string fullname: the full and unique name of this type

           •   string shortname: A short (one-character long) name of this type which is used in
               the output of the attr command

       •   color: Type representing colors. A color can be defined in one of the following
           formats:

            1. #RRGGBB where R, G, B are hexidecimal digits (0-9, A-F), and RR, GG, BB represent
               the values for red, green, blue.

            2. #RRGGBBAA represents a color with alpha-value AA. The alpha value 00 is fully
               transparent and FF is fully opaque/intransparent.

            3. a common color name like red, blue, orange, etc. For attributes and children, see
               types.booldecimal: Fixed precision decimal numbers, e.g. 0.34. For attributes and children, see
           types.boolfont: A font specification (font family with modifiers regarding size, weight, etc.)
           in one of the following formats:

           •   Fontconfig description. This supports antialiased fonts, for example:

               •   Dejavu Sans:pixelsize=12Bitstream Vera Sans:size=12:bold

           •   X logical font description (XLFD), as provided by the xfontsel tool. No
               antialiasing is supported here, but this is usually superior for bitmap fonts. For
               example:

               •   -*-fixed-medium-r-*-*-13-*-*-*-*-*-*-* for a standard bitmap font available on
                   most systems. For attributes and children, see types.boolint: Type representing signed integers. When overwriting an integer, you can increase
           or decrease its value relatively by writing +=N or -=N where N is an integer. So for
           example, writing +=3 to an attribute increases its value by 3. For attributes and
           children, see types.boolnames: A fixed set of names, depending on the context, e.g. names of layout algorithms
           or the split type of a non-leaf frame (which is only horizontal or vertical). For
           attributes and children, see types.boolrectangle: A rectangle on the screen consisting of a size and the position on the
           screen. The format is WxH+X+Y where W is the width, H is the height, and X and Y are
           the coordinates of the top left corner of the rectangle: X is the number of pixels to
           the left screen edge and Y is the number of pixels to the top screen edge. (if X or Y
           is negative, then the + turns into -). For example: 800x600+800+0 or 400x200-10+30.
           For attributes and children, see types.boolregex: A POSIX extended regular expression. Note that when passing a regex on the
           command line, additional quoting can be necessary. For explanations and examples, see
           section 9.4.6 of the documentation:
           https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap09.html#tag_09_04_06.
           For attributes and children, see types.boolstring: Type representing normal text. For attributes and children, see types.booluint: Type representing unsigned (i.e. non-negative) integers. When overwriting an
           integer, you can increase or decrease its value relatively by writing +=N or -=N where
           N is an integer. For attributes and children, see types.boolwindowid: The window id is the number of a window. This can be a managed window (i.e.
           client) or an unmanaged window (e.g. a panel, a menu, or a desktop window). The
           default format is 0xHEX where HEX is a hexadecimal number (digits 0-9 and a-f) but it
           can also be specified in the decimal system (base 10), or as an octal number (with
           prefix 0 and base 8). When a window id is printed, it is always printed in the 0xHEX
           format and without any leading zeroes. For attributes and children, see types.bool

   watchers:uint count: the number of attributes that are watched

AUTOSTART FILE

       There is no configuration file but an autostart file, which is executed on startup. It is
       also executed on command reload. If not specified by the --autostart argument, autostart
       file is located at $XDG_CONFIG_HOME/herbstluftwm/autostart or at
       ~/.config/herbstluftwm/autostart. Normally it consists of a few herbstclient calls. If
       executing the autostart file in a user’s home fails the global autostart file (mostly
       placed at /etc/xdg/herbstluftwm/autostart) is executed as a fallback.

       For a quick install, copy the default autostart file to ~/.config/herbstluftwm/.

HOOKS

       On special events, herbstluftwm emits some hooks (with parameters). You can receive or
       wait for them with herbstclient(1). Also custom hooks can be emitted with the emit_hook
       command. The following hooks are emitted by herbstluftwm itself:

       attribute_changed PATH OLDVALUE NEWVALUE
           The attribute PATH was changed from OLDVALUE to NEWVALUE. Requires that the attribute
           PATH has been passed to the watch command before.

       fullscreen [on|off] WINID
           The fullscreen state of window WINID was changed to [on|off].

       tag_changed TAG MONITOR
           The tag TAG was selected on MONITOR.

       focus_changed WINID TITLE
           The window WINID was focused. Its window title is TITLE.

       window_title_changed WINID TITLE
           The title of the focused window was changed. Its window id is WINID and its new title
           is TITLE.

       tag_flags
           The flags (i.e. urgent or filled state) have been changed.

       tag_added TAG
           A tag named TAG was added.

       tag_removed TAG
           The tag named TAG was removed.

       tag_renamed OLD NEW
           The tag name changed from OLD to NEW.

       urgent [on|off] WINID
           The urgent state of client with given WINID has been changed to [on|off].

       rule NAME WINID
           A window with the id WINID appeared which triggered a rule with the consequence
           hook=NAME.

       There are also other useful hooks, which never will be emitted by herbstluftwm itself, but
       which can be emitted with the emit_hook command:

       quit_panel
           Tells a panel to quit. The default panel.sh quits on this hook. Many scripts are using
           this hook.

       reload
           Tells all daemons that the autostart file is reloaded — and tells them to quit. This
           hook should be emitted in the first line of every autostart file.

STACKING

       Every tag has its own stack of clients that are on this tag. Similar to the EWMH
       specification each tag stack contains several layers, which are from top to bottom:

       •   the focused client (if raise_on_focus_temporarily is enabled)

       •   clients in fullscreen

       •   normal clients

       •   frame decorations

       All monitors are managed in one large stack which only consists of the stacks of the
       visible tags put above each other. The stacking order of these monitors is independent
       from their indices and can be modified using the raise_monitor command. The current stack
       is illustrated by the stack command.

EWMH AND X11 PROPERTIES

       As far as possible, herbstluftwm tries to be EWMH compliant. That includes:

       •   Information about tag names and client lists is provided.

       •   Desktop windows from desktop environments are not managed and kept below the other
           windows.

       •   Client requests like getting focused are only processed if the setting
           focus_stealing_prevention is disabled.

       Moreover, herbstluftwm sets the X11 properties HLWM_FLOATING_WINDOW and HLWM_TILING_WINDOW
       to indicate whether a window is in floating or tiling mode, that is, the value of the
       client’s floating_effectively attribute.

ENVIRONMENT VARIABLES

       DISPLAY
           Specifies the DISPLAY to use.

FILES

       The following files are used by herbstluftwm:

       •   autostart, see section AUTOSTART FILE.

EXIT STATUS

       Returns 0 on success. Returns EXIT_FAILURE if it cannot startup or if wmexec fails.
