It also listens for calls from \fBherbstclient\fR(1) and executes them\&. The list of available \fBCOMMANDS\fR is listed below\&. .sp \fIOPTION\fR can be: .PP \fB\-c\fR, \fB\-\-autostart\fR \fIPATH\fR .RS 4 use \fIPATH\fR as autostart file instead of the one in \fI$XDG_CONFIG_HOME\fR .RE .PP \fB\-v\fR, \fB\-\-version\fR .RS 4 print version and exit .RE .PP \fB\-l\fR, \fB\-\-locked\fR .RS 4 Initially set the monitors_locked setting to 1 .RE .PP \fB\-\-verbose\fR .RS 4 print verbose information to stderr\&. This can be switched at run\-time by the \fIverbose\fR setting\&. .RE .sp This manual documents the scripting and configuration interface\&. For a more verbose introduction see \fBherbstluftwm\-tutorial\fR(7)\&. .SH "TILING ALGORITHM" .sp 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: .sp .RS 4 .ie n \{\ \h'-04' 1.\h'+01'\c .\} .el \{\ .sp -1 .IP " 1." 4.2 .\} Frame contains windows: It shows some clients and arranges them\&. The current layout algorithms are: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 0: \fIvertical\fR \- clients are placed below each other .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 1: \fIhorizontal\fR \- clients are placed next to each other .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 2: \fImax\fR \- all clients are maximized in this frame .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 3: \fIgrid\fR \- clients are arranged in an almost quadratic grid .RE .RE .sp .RS 4 .ie n \{\ \h'-04' 2.\h'+01'\c .\} .el \{\ .sp -1 .IP " 2." 4.2 .\} Frame is split into subframes: It is split into exactly two \fBsubframes\fR in a configurable \fIfraction\fR either in a vertical or horizontal way\&. So it produces two \fBframes\fR which fulfill the same conditions (new frames always are about to contain \fBwindows\fR)\&. If you split a frame that already contains windows, the windows are inherited by the first new child frame\&. .RE .sp If a new window appears, it is put in the currently focused frame\&. Only the leaves of the frame tree can be focused\&. .sp 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\&. .sp 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: .sp .if n \{\ .RS 4 .\} .nf C .fi .if n \{\ .RE .\} .sp When splitting it (e\&.g\&. with the command \fIsplit vertical 0\&.5\fR) you will get this: .sp .if n \{\ .RS 4 .\} .nf V / \e C C .fi .if n \{\ .RE .\} .sp You also can split the left frame horizontally and you will get: .sp .if n \{\ .RS 4 .\} .nf V / \e H C / \e C C .fi .if n \{\ .RE .\} .sp 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: .sp .if n \{\ .RS 4 .\} .nf H / \e C C .fi .if n \{\ .RE .\} .sp The \fIlayout\fR command prints the current layout of all tags as a tree\&. .SH "FRAME INDEX" .sp The exact position of a frame in the layout tree may be described by its \fBindex\fR 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\&. .sp The characters are interpreted as follows: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 0: select the first subtree .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 1: select the second subtree .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \&.: select the subtree having the focus .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} /: select the subtree not having the focus .RE .sp Thus an empty string refers to the root frame, and "00" refers to the first subtree of the first subtree of the root frame\&. .sp As a special case, the string "@" always refers to the currently focused frame\&. .SH "TAGS" .sp 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\&. .SH "MONITORS" .sp Monitors in \fBherbstluftwm\fR 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\&. .sp Each monitor displays exactly one tag on a specified rectangle on the screen\&. .sp Each monitor may have a name, which can be set via \fBadd_monitor\fR and \fBrename_monitor\fR\&. It can be unset with the \fBrename_monitor\fR command\&. A monitor name is an arbitrary non\-empty string which must not start with +, \- or any digit\&. .sp A monitor can be referenced in different ways: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} by its absolute index as listed in the \fBlist_monitors\fR command\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} by its relative index: a + or \- followed by a delta, e\&.g\&.: +3 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} 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\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} by "" (an empty string) which represents the current monitor\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} by its name\&. .RE .SH "COMMANDS" .sp \fBherbstluftwm\fR is controlled by internal commands, which can be executed via \fBherbstclient\fR(1) or via keybindings\&. .PP quit .RS 4 Quits herbstluftwm\&. .RE .PP reload .RS 4 Executes the autostart file\&. .RE .PP version .RS 4 Prints the version of the running herbstluftwm instance\&. .RE .PP echo [\fIARGS\fR \&...] .RS 4 Prints all given \fIARGS\fR separated by a single space and a newline afterwards\&. .RE .PP true .RS 4 Ignores all arguments and always returns success, i\&.e\&. 0\&. .RE .PP false .RS 4 Ignores all arguments and always returns failure, i\&.e\&. 1\&. .RE .PP list_commands .RS 4 Lists all available commands\&. .RE .PP list_monitors .RS 4 List currently configured monitors with their index, area (as rectangle), name (if named) and currently viewed tag\&. .RE .PP list_rules .RS 4 Lists all active rules\&. Each line consists of all the parameters the rule was called with, plus its label, separated by tabs\&. .RE .PP list_keybinds .RS 4 Lists all bound keys with their associated command\&. Each line consists of one key combination and the command with its parameters separated by tabs\&. .RE .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBWarning\fR .ps -1 .br .sp Tabs within command parameters are not escaped! .sp .5v .RE .PP lock .RS 4 Increases the \fImonitors_locked\fR setting\&. Use this if you want to do multiple window actions at once (i\&.e\&. without repainting between the single steps)\&. See also: \fBunlock\fR .RE .PP unlock .RS 4 Decreases the \fImonitors_locked\fR setting\&. If \fImonitors_locked\fR is changed to 0, then all monitors are repainted again\&. See also: \fBlock\fR .RE .PP keybind \fIKEY\fR \fICOMMAND\fR [\fIARGS \&...\fR] .RS 4 Adds a key binding\&. When \fIKEY\fR is pressed, the internal \fICOMMAND\fR (with its \fIARGS\fR) 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 \fI\-\fR or \fI+\fR as separator\&. If there is already a binding for this \fIKEY\fR, it will be overwritten\&. Examples: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} keybind Mod4+Ctrl+q quit .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} keybind Mod1\-i toggle always_show_frame .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} keybind Mod1\-Shift\-space cycle_layout \-1 .RE .RE .PP keyunbind \fIKEY\fR|\fB\-F\fR|\fB\-\-all\fR .RS 4 Removes the key binding for \fIKEY\fR\&. The syntax for \fIKEY\fR is defined in \fBkeybind\fR\&. If \fB\-F\fR or \fB\-\-all\fR is given, then all key bindings will be removed\&. .RE .PP mousebind \fIBUTTON\fR \fIACTION\fR [\fICOMMAND\fR \&...] .RS 4 Adds a mouse binding for the floating mode\&. When \fIBUTTON\fR is pressed, the specified \fIACTION\fR will be performed\&. \fIBUTTON\fR has a similar syntax to the \fIKEY\fR argument of keybind: It consists of a list of modifiers (separated by \fI\-\fR or \fI+\fR, valid modifiers are listed in the description of \fIkeybind\fR) and exactly one button name: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} B1 or Button1 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} B2 or Button2 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} B3 or Button3 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} B4 or Button4 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} B5 or Button5 .RE .RE .PP .RS 4 \fIACTION\fR must be one of the following actions: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} move: Moves the window by dragging the cursor\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} resize: Resizes the window by dragging a corner\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} zoom: Resizes the window into all four directions while keeping the center of the window constant\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} call: Only calls the specified \fICOMMAND\fR while client\&.dragged links to the client on which the \fIBUTTON\fR has been performed\&. .RE .RE .PP .RS 4 While an \fIACTION\fR is performed, client\&.dragged is the client which is dragged\&. E\&.g\&.: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} mousebind Mod1\-Button3 zoom .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} mousebind Mod1\-B4 call substitute WID clients\&.dragged\&.winid spawn transset\-df \-\-inc \-i WID 0\&.05 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} mousebind Mod1\-B5 call substitute WID clients\&.dragged\&.winid spawn transset\-df \-\-dec \-i WID \-m 0\&.2 0\&.05 .RE .RE .PP mouseunbind .RS 4 Removes all mouse bindings\&. .RE .PP spawn \fIEXECUTABLE\fR [\fIARGS \&...\fR] .RS 4 Spawns an \fIEXECUTABLE\fR with its \fIARGS\fR\&. For details see \fIman 3 execvp\fR\&. Example: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} spawn xterm \-e man 3 execvp .RE .RE .PP wmexec [\fIWINDOWMANAGER\fR [\fIARGS \&...\fR]] .RS 4 Executes the \fIWINDOWMANAGER\fR with its \fIARGS\fR\&. This is useful to switch the window manager in the running session without restarting the session\&. If no or an invalid \fIWINDOWMANAGER\fR is given, then herbstluftwm is restarted\&. For details see \fIman 3 execvp\fR\&. Example: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} wmexec openbox .RE .RE .PP chain \fISEPARATOR\fR [\fICOMMANDS\fR \&...] .RS 4 chain expects a \fISEPARATOR\fR and a list of \fICOMMANDS\fR with arguments\&. The commands have to be separated by the specified \fISEPARATOR\fR\&. The \fISEPARATOR\fR can by any word and only is recognized as the separator between commands if it exactly matches \fISEPARATOR\fR\&. "chain" outputs the appended outputs of all commands and returns the exit code of the last executed command\&. Examples are: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Create a tag called "foo" and directly use it: chain , add foo , use foo .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Rotate the layout clockwise: chain \&.\-\&. lock \&.\-\&. rotate \&.\-\&. rotate \&.\-\&. rotate \&.\-\&. unlock .RE .RE .PP .RS 4 Counterexamples are: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} This will only create a tag called "foo,": chain , add foo, use foo .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Separator "\&." defined, but "," is used: chain \&. add foo , use foo .RE .RE .PP and \fISEPARATOR\fR [\fICOMMANDS\fR \&...] .RS 4 "and" behaves like the chain command but only executes the specified \fICOMMANDS\fR while the commands return the exit code 0\&. .RE .PP or \fISEPARATOR\fR [\fICOMMANDS\fR \&...] .RS 4 "or" behaves like the chain command but only executes the specified \fICOMMANDS\fR until one command returns the exit code 0\&. .RE .PP ! \fICOMMAND\fR .RS 4 "!" 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\&. .RE .PP try \fICOMMAND\fR .RS 4 "try" executes the provided command, prints its output, but always returns success, i\&.e\&. 0\&. .RE .PP silent \fICOMMAND\fR .RS 4 "silent" executes the provided command, but discards its output and only returns its exit code\&. .RE .PP focus_nth \fIINDEX\fR .RS 4 Focuses the nth window in a frame\&. The first window has \fIINDEX\fR 0\&. If \fIINDEX\fR is negative or greater than the last window index, then the last window is focused\&. .RE .PP cycle [\fIDELTA\fR] .RS 4 Cycles the selection within the current frame by \fIDELTA\fR\&. If \fIDELTA\fR is omitted, \fIDELTA\fR = 1 will be used\&. \fIDELTA\fR can be negative; \fIDELTA\fR = \-1 means: cycle in the opposite direction by 1\&. .RE .PP cycle_all [\fB\-\-skip\-invisible\fR] [\fIDIRECTION\fR] .RS 4 Cycles through all windows and frames on the current tag\&. \fIDIRECTION\fR = 1 means forward, \fIDIRECTION\fR = \-1 means backward, \fIDIRECTION\fR = 0 has no effect\&. \fIDIRECTION\fR defaults to 1\&. If there are multiple windows within on frame, then it acts similar to the \fIcycle\fR command\&. (The \fIcycle_all\fR command focuses the next/previous leaf in the \fIlayout\fR tree\&.)\&. If \fB\-\-skip\-invisible\fR is given, then this only cycles through all visible windows and skips invisible windows in the max layout\&. The focused window is raised\&. .RE .PP cycle_frame [\fIDIRECTION\fR] .RS 4 Cycles through all frames on the current tag\&. \fIDIRECTION\fR = 1 means forward, \fIDIRECTION\fR = \-1 means backward, \fIDIRECTION\fR = 0 has no effect\&. \fIDIRECTION\fR defaults to 1\&. .RE .PP cycle_layout [\fIDELTA\fR [\fILAYOUTS\fR \&...]] .RS 4 Cycles the layout algorithm in the current frame by \fIDELTA\fR\&. \fIDELTA\fR defaults to 1\&. You can find a list of layout algorithms above\&. If a list of \fILAYOUTS\fR 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 \fILAYOUTS\fR and picking the next layout according to \fIDELTA\fR\&. If the current layout doesn\(cqt occur in \fILAYOUTS\fR, the first entry is picked\&. Example: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} cycle_layout \-1 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} cycle_layout 1 vertical grid .RE .RE .PP set_layout \fILAYOUT\fR .RS 4 Sets the layout algorithm in the current frame to \fILAYOUT\fR\&. For the list of layouts, check the list of layout algorithms above\&. .RE .PP close \fIWINID\fR .RS 4 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\&. .RE .PP close_or_remove .RS 4 Closes the focused window or removes the current frame if no window is focused\&. .RE .PP close_and_remove .RS 4 Closes the focused window and removes the current frame if no other window is present in that frame\&. .RE .PP split \fIALIGN\fR [\fIFRACTION\fR] .RS 4 Splits the focused frame into two subframes with a specified \fIFRACTION\fR between 0 and 1 which defaults to 0\&.5\&. \fIALIGN\fR is one of .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fItop\fR .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIbottom\fR (= \fIvertical\fR) .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIleft\fR, .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIright\fR (= \fIhorizontal\fR) .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIexplode\fR .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIauto\fR (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 \fIALIGN\fR mode is \fIexplode\fR, which splits the frame in such a way that the window sizes and positions are kept as much as possible\&. If no \fIFRACTION\fR is given to \fIexplode\fR mode an optimal fraction is picked automatically\&. Example: .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} split explode .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} split bottom 0\&.5 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} split horiz 0\&.3 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} split vertical 0\&.5 .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} split h .RE .RE .PP focus [\fI\-i\fR|\fI\-e\fR] \fIDIRECTION\fR .RS 4 Moves the focus from current frame to the next frame or client in \fIDIRECTION\fR which is in: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} l[eft] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} r[ight] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} u[p] .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} d[own] .RE .RE .PP .RS 4 If \fI\-i\fR (internal) is given or default_direction_external_only is unset, then the next client in \fIDIRECTION\fR can also be within the same frame\&. If there is no client within this frame or \fI\-e\fR (external) is given, then the next frame in specified \fIDIRECTION\fR 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 \fIDIRECTION\fR\&. From there the focus goes back to the leaf\&. Example: The focus is at frame A\&. After executing \fIfocus right\fR focus will be at frame C\&. .sp .if n \{\ .RS 4 .\} .nf 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 └─────┘└─────┘ .fi .if n \{\ .RE .\} .RE .PP .RS 4 If the currently focused client is floated, then the next floating window in the specified direction is focused and raised\&. .RE .PP .RS 4 If \fIfocus_crosses_monitor_boundaries\fR is set and no client or frame is found in the specified \fIDIRECTION\fR, then the next monitor in that \fIDIRECTION\fR is focused\&. .RE .PP focus_edge [\fI\-i\fR|\fI\-e\fR] \fIDIRECTION\fR .RS 4 Focuses the window on the edge of the tag in the specified \fIDIRECTION\fR\&.

If \fI\-i\fR (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\&. .RE .PP raise \fIWINID\fR .RS 4 Raises the specified window\&.

You can receive or wait for them with \fBherbstclient\fR(1)\&. Also custom hooks can be emitted with the \fBemit_hook\fR command\&. The following hooks are emitted by herbstluftwm itself: .PP fullscreen [on|off] \fIWINID\fR \fISTATE\fR .RS 4 The fullscreen state of window \fIWINID\fR was changed to [on|off]\&. .RE .PP tag_changed \fITAG\fR \fIMONITOR\fR .RS 4 The tag \fITAG\fR was selected on \fIMONITOR\fR\&. .RE .PP focus_changed \fIWINID\fR \fITITLE\fR .RS 4 The window \fIWINID\fR was focused\&.

The default panel\&.sh quits on this hook\&. Many scripts are using this hook\&. .RE .PP reload .RS 4 Tells all daemons that the \fIautostart\fR file is reloaded \(em and tells them to quit\&. This hook \fBshould\fR be emitted in the first line of every \fIautostart\fR file\&. .RE .SH "STACKING" .sp 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: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} the focused client (if raise_on_focus_temporarily is enabled) .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} clients in fullscreen .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} normal clients .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} frame decorations .RE .sp 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 \fBraise_monitor\fR command\&. The current stack is illustrated by the \fBstack\fR command\&. .SH "EWMH" .sp As far as possible, herbstluftwm tries to be EWMH compliant\&. That includes: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Information about tag names and client lists is provided\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Desktop windows from desktop environments are not managed and kept below the other windows\&. .RE .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} Client requests like getting focused are only processed if the setting \fIfocus_stealing_prevention\fR is disabled\&. .RE .SH "ENVIRONMENT VARIABLES" .PP DISPLAY .RS 4 Specifies the \fIDISPLAY\fR to use\&. .RE .SH "FILES" .sp The following files are used by herbstluftwm: .sp .RS 4 .ie n \{\ \h'-04'\(bu\h'+03'\c .\} .el \{\ .sp -1 .IP \(bu 2.3 .\} \fIautostart\fR, see section \fBAUTOSTART FILE\fR\&. .RE .SH "EXIT STATUS" .sp Returns \fB0\fR on success\&.
