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:

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

       -v, --version
           print version and exit

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

       --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 current layout algorithms are:

           ·   0: vertical - clients are placed below each other

           ·   1: horizontal - clients are placed next to each other

           ·   2: max - all clients are maximized in this frame

           ·   3: 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 selects one
       of its two subtrees according to the each character in the index.

       The characters are interpreted 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

       Thus an empty string refers to the root frame, and "00" refers to the first subtree of the
       first subtree of the root frame.

       As a special case, the string "@" always refers to the currently 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.

       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!

       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. 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 there is
           already a binding for this KEY, it will be overwritten. Examples:

           ·   keybind Mod4+Ctrl+q quit

           ·   keybind Mod1-i toggle always_show_frame

           ·   keybind Mod1-Shift-space cycle_layout -1

       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 Button1

           ·   B2 or Button2

           ·   B3 or Button3

           ·   B4 or Button4

           ·   B5 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 zoom

           ·   mousebind Mod1-B4 call substitute WID clients.dragged.winid spawn transset-df
               --inc -i WID 0.05

           ·   mousebind Mod1-B5 call substitute WID clients.dragged.winid spawn transset-df
               --dec -i WID -m 0.2 0.05

       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. 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 windows and frames on the current tag.  DIRECTION = 1 means
           forward, DIRECTION = -1 means backward, DIRECTION = 0 has no effect.  DIRECTION
           defaults to 1. If there are multiple windows within on frame, then it acts similar to
           the cycle command. (The cycle_all command focuses the next/previous leaf in the layout
           tree.). If --skip-invisible is given, then this only cycles through all visible
           windows and skips invisible windows in the max layout. 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.

       close_and_remove
           Closes the focused window and removes the current frame if no other window is present
           in that frame.

       split ALIGN [FRACTION]
           Splits the focused frame into two subframes with a specified FRACTION between 0 and 1
           which defaults to 0.5.  ALIGN is one of

           ·   top

           ·   bottom (= vertical)

           ·   left,

           ·   right (= horizontal)

           ·   explode

           ·   auto (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
               focuse frame will stay focused. One special ALIGN mode is explode, which splits
               the frame in such a way that the window sizes and positions are kept as much as
               possible. If no FRACTION is given to explode mode an optimal fraction is picked
               automatically. Example:

           ·   split explode

           ·   split bottom 0.5

           ·   split horiz 0.3

           ·   split vertical 0.5

           ·   split h

       focus [-i|-e] 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 -i (internal) is given or default_direction_external_only is unset, then the next
           client in DIRECTION can also be within the same frame. If there is no client within
           this frame or -e (external) is given, then the next frame in specified DIRECTION will
           be focused.

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

                Tree:  V,0     Screen: ┌─────┐┌─────┐ (after focus right)
                       ╱ ╲             │  B  ││  C* │
                      ╱   ╲            └─────┘└─────┘
                    H,1   H,0          ┌─────┐┌─────┐
                    ╱ ╲   ╱ ╲          │  A  ││  D  │
                   A   B 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 window. See the section on WINDOW IDS on how to reference a
           certain window. Its result is only visible in floating mode.

           Tip
           The WINID also can specify an unmanaged window, although the completion for the raise
           command does not list the IDs of unmanaged 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. See the section on
           WINDOW IDS on how to reference a certain window.

       resize DIRECTION FRACTIONDELTA
           Changes the next fraction in specified DIRECTION by FRACTIONDELTA.  DIRECTION behaves
           as specified at the focus command. You should not omit the sign - or +, because in
           future versions, the behaviour may change if the sign is omitted. 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.

       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 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.

       set NAME VALUE
           Sets the specified setting NAME to 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 an integer setting: If its value is unequal to 0, it
           becomes 0; else its previous value (which was unequal to 0) is restored.

       cycle_value NAME VALUES ...
           Cycles value of the setting NAME 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. Example:

           ·   cycle_value frame_gap 0 5 10 15

           ·   cycle_value frame_bg_normal_color red green blue

       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 then monitors

           ·   Existing monitors are deleted if there are more monitors then RECTS

       detect_monitors -l|--list|--no-disjoin
           Sets the list of monitors to the available Xinerama monitors. If the Xinerama
           extension is 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 pyhsical monitors is
           printed. So hc detect_monitors is equivalent to the bash command hc set_monitors $(hc
           disjoin_rects $(hc detect_monitors -l)).

       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. 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 ARGS ...
           Emits a custom hook 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 the current tag to floating/tiling mode on specified TAG or prints it 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.

       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.

       new_attr [bool|color|int|string|uint] PATH
           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_.

       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 [ATTRIBUTES ...] COMMAND [ARGS ...]
           Replaces all exact occurrences of IDENTIFIER in COMMAND and its ARGS by the string
           specified by FORMAT. Each %s in FORMAT stands for the value of the next attribute in
           ATTRIBUTES, similar to the printf(1) command. 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 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.

       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 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 VALUE

           ·   le: ATTRIBUTE's value <= VALUE

           ·   lt: ATTRIBUTE's value < VALUE

           ·   ge: ATTRIBUTE's value >= VALUE

           ·   gt: 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.

       unsetenv NAME
           Unsets the environment variable NAME.

SETTINGS

       Settings configure the behaviour of herbstluftwm and can be controlled via the set, get
       and toggle commands. There are two types of settings: Strings and integer values. An
       integer value is set, if its value is 1 or another value unequal to 0. An integer value is
       unset, if its value is 0.

       frame_gap (Integer)
           The gap between frames in the tiling mode.

       frame_padding (Integer)
           The padding within a frame in the tiling mode, i.e. the space between the border of a
           frame and the windows within it.

       window_gap (Integer)
           The gap between windows within one frame in the tiling mode.

       snap_distance (Integer)
           If a client is dragged in floating mode, then it snaps to neighbour clients if the
           distance between them is smaller then snap_distance.

       snap_gap (Integer)
           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.

       mouse_recenter_gap (Integer)
           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.

       frame_border_active_color (String/Color)
           The border color of a focused frame.

       frame_border_normal_color (String/Color)
           The border color of an unfocused frame.

       frame_border_inner_color (String/Color)
           The color of the inner border of a frame.

           The fill color of an unfocused frame (It is only visible if always_show_frame is set).

       frame_bg_transparent (Integer)
           If set, the background of frames are transparent. That means a rectangle is cut out
           frome 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.

       frame_transparent_width (Integer)
           Specifies the width of the remaining frame colored with frame_bg_active_color if
           frame_bg_transparent is set.

       frame_border_width (Integer)
           Border width of a frame.

       frame_border_inner_width (Integer)
           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.

       focus_crosses_monitor_boundaries (Integer)
           If set, the focus command crosses monitor boundaries. If there is no client in the
           direction given to focus, then the monitor in the specified direction is focused.

       raise_on_focus (Integer)
           If set, a window is raised if it is focused. The value of this setting is only used in
           floating mode.

       raise_on_focus_temporarily (Integer)
           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.

       raise_on_click (Integer)
           If set, a window is raised if it is clicked. The value of this setting is only noticed
           in floating mode.

       window_border_width (Integer)
           Border width of a window.

       window_border_inner_width (Integer)
           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.

       window_border_active_color (String/Color)
           Border color of a focused window.

       window_border_normal_color (String/Color)
           Border color of an unfocused window.

       window_border_urgent_color (String/Color)
           Border color of an unfocused but urgent window.

       window_border_inner_color (String/Color)
           Color of the inner border of a window.

       always_show_frame (Integer)
           If set, all frames are displayed. If unset, only frames with focus or with windows in
           it are displayed.

       frame_active_opacity (Integer)
           Focused frame opacity in percent. Requires a running compositing manager to take
           actual effect.

       frame_normal_opacity (Integer)
           Unfocused frame opacity in percent. Requires a running compositing manager to take
           actual effect.

       default_frame_layout (Integer)
           Index of the frame layout, which is used if a new frame is created (by split or on a
           new tag). For a list of valid indices and their meanings, check the list of layout
           algorithms above.

       default_direction_external_only (Integer)
           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.

       gapless_grid (Integer)
           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.

       smart_frame_surroundings (Integer)
           If set, frame borders and gaps will be removed when there’s no ambiguity regarding the
           focused frame.

       smart_window_surroundings (Integer)
           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.

       focus_follows_mouse (Integer)
           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.

       focus_stealing_prevention (Integer)
           If set, only pagers and taskbars are allowed to change the focus. If unset, all
           applications can request a focus change.

       monitors_locked (Integer)
           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.

       swap_monitors_to_get_tag (Integer)
           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.

       auto_detect_monitors (Integer)
           If set, detect_monitors is automatically executed every time a monitor is connected,
           disconnected or resized.

       tree_style (String)
           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-.root
                 #-. child 0
                 | #-* child 01
                 | +-* child 02
                 +-. child 1
                 : #-* child 10
                 : +-* child 01

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

       wmname (String)
           It controls the value of the _NET_WM_NAME property on the root window, which specifies
           the name of the running window manager. The value of this setting is not updated if
           the actual _NET_WM_NAME property on the root window is changed externally. Example
           usage:

           ·   cycle_value wmname herbstluftwm LG3D

       pseudotile_center_threshold (Int)
           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.

       update_dragged_clients (Int)
           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 are released.

       verbose (Int)
           If set, verbose output is logged to herbstluftwm’s stderr. The default value is
           controlled by the --verbose command line flag.

RULES

       Rules are used to change default properties for certain clients when they appear. 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 properly 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).

       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.

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

       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 on his tag. The default is off.  VALUE
           can be on, off or toggle.

       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 can be on, off or toggle.

       manage
           decides whether the client will be managed or not. The default is on.  VALUE can be
           on, off or toggle.

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

       pseudotile
           sets the pseudotile state of the client.  VALUE can be on, off or toggle.

       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 can be on, off or toggle, 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 can be on, off or toggle, it defaults to on.

       fullscreen
           sets the fullscreen flag of the client.  VALUE can be on, off or toggle.

       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 an client. A keymask is an regular expression that is matched
           against the string represenation (see list_keybinds). If it matches the keybinding is
           active when this client is focused, otherwise it is disabled. The default keymask is
           an empty string (""), which does not disable any keybinding.

       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 is HEXID.

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

OBJECTS

           Warning
           The object tree is not stable yet, i.e. its interface may change until the next stable
           release. So check this documentation again after upgrading the next time.

       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
            | .-- writeable
            V V
            u - count                = 9

           $ herbstclient attr tags.focus.
           0 children.
           6 attributes:
            .---- type
            | .-- writeable
            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

           ·   s for string

           ·   i for integer

           ·   b for boolean

           ·   u for unsigned integer

       ·   if it is writeable 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 writeable 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

       Just look around to get a feeling what is there. The detailed tree content is listed as
       follows:

       ·   tags: subtree for tags.

           Setting an attribute of the theme object just propagates the value to the respective
           attribute of the tiling and the floating object.

           ·   tiling configures the decoration of tiled clients, setting one of its attributes
               propagates the respective attribute of the active, normal and urgent child
               objects.

               ·   active configures the decoration of focused and tiled clients

               ·   normal configures the decoration of unfocused and tiled clients

               ·   urgent configures the decoration of urgent and tiled clients

           ·   floating behaves analogously to tiling

           ·   minimal behaves analogously to tiling and configures those minimal decorations
               triggered by smart_window_surroundings.

           ·   active propagates the attribute values to tiling.active and floating.active

           ·   normal propagates the attribute values to tiling.normal and floating.normal

           ·   urgent propagates the attribute values to tiling.urgent and floating.urgent

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:

       fullscreen [on|off] WINID STATE
           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.

       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

       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.

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.
