spectrwm man page
spectrwm — window manager for X11
spectrwm is a minimalistic window manager that tries to stay out of the way so that valuable screen real estate can be used for much more important stuff. It has sane defaults and does not require one to learn a language to do any configuration. It was written by hackers for hackers and it strives to be small, compact and fast.
When spectrwm starts up, it reads settings from its configuration file,
spectrwm.conf. See the Configuration Files section below.
The following notation is used throughout this page:
Named key or button
spectrwm is very simple in its use. Most of the actions are initiated via key or pointer bindings. See the Bindings section below for defaults and customizations.
spectrwm first tries to open the user specific file,
~/.spectrwm.conf. If that file is unavailable, it then tries to open the global configuration file
The format of the file is
keyword = setting
color_focus = red
Enabling or disabling an option is done by using 1 or 0 respectively.
Colors need to be specified per the XQueryColor(3) specification.
Comments begin with a #. When a literal ‘
#’ is desired in an option, then it must be escaped with a backslash, i.e. \#
The file supports the following keywords:
Launch an application in a specified workspace at start-of-day. Defined in the format
ws[idx]:application, e.g. ws:xterm launches an xterm(1) in workspace 2.
Note that workspace mapping is handled via
autorunspawns windows via a daemon, ensure the daemon is started with the correct
LD_PRELOADin its environment.
For example, starting urxvtd(1) via xinit(1):
LD_PRELOAD=/usr/lib/libswmhack.so.0.0 urxvtd -q -o -f
Spawned programs automatically have
LD_PRELOADset when executed.
External script that populates additional information in the status bar, such as battery life.
Place the statusbar at the bottom of each region instead of the top.
Border color of the status bar(s) in screen x.
Border color of the status bar(s) on unfocused region(s) in screen x.
Set status bar border thickness in pixels. Disable border by setting to 0.
Background color of the status bar(s) in screen x.
Background color for selections on the status bar(s) in screen x. Defaults to the value of
bar_togglestate; default is 1.
bar_toggle_wsstate on workspace x; default is 1.
Font used in the status bar. Either Xft or X Logical Font Description (XLFD) may be used to specify fonts. Fallback fonts may be specified by separating each font with a comma. If all entries are in XLFD syntax, font set will be used. If at least one entry is Xft, Xft will be used. Note that if Xft is in use, only the first font that successfully loads will be used regardless of missing glyphs. The default is to use font set. Also note that dmenu(1) does not support Xft fonts.
bar_font = Terminus:style=Regular:pixelsize=14:antialias=true bar_font = -*-profont-medium-*-*-*-11-*-*-*-*-*-*-*,Terminus:pixelsize=14,-*-clean-medium-*-*-*-12-*-*-*-*-*-*-*
Font set examples:
bar_font = -*-terminus-medium-*-*-*-14-*-*-*-*-*-*-* bar_font = -*-profont-medium-*-*-*-11-*-*-*-*-*-*-*,-*-terminus-medium-*-*-*-14-*-*-*-*-*-*-*,-*-clean-medium-*-*-*-12-*-*-*-*-*-*-*
To list the available fonts in your system see fc-list(1) or xlsfonts(1) manpages. The xfontsel(1) application can help with the XLFD setting.
Foreground color of the status bar(s) in screen x.
Foreground color for selections on the status bar(s) in screen x. Defaults to the value of
Set the bar format string, overriding
clock_formatand all of the
enabledoptions. The format is passed through strftime(3) before being used. It may contain the following character sequences:
Character sequence Replaced with
Pad with a space
Output of the external script
Window class (from WM_CLASS)
Workspace list indicator
Number of iconic (minimized) windows in workspace
Window class and instance separated by a colon
Window instance (from WM_CLASS)
Window name (from _NET_WM_NAME/WM_NAME)
A literal ‘
All character sequences may limit its output to a specific length, for example +64A. By default, no padding/alignment is done in case the length of the replaced string is less than the specified length (64 in the example). The padding/alignment can be enabled using a '_' character in the sequence. For example: +_64W, +64_W and +_64_W enable padding before (right alignment), after (left alignment), and both before and after (center alignment) window name, respectively. Any characters that don't match the specification are copied as-is.
Justify the status bar text. Possible values are left, center, and right.
Note that if the output is not left justified, it may not be properly aligned in some circumstances, due to the white-spaces in the default static format. See the
bar_formatoption for more details.
Bind key or button combo to action x. See the Bindings section below.
Set window border thickness in pixels. Disable all borders by setting to 0.
Set region containment boundary width in pixels. This is how far a window must be dragged/resized (with the pointer) beyond the region edge before it is allowed outside the region. Disable the window containment effect by setting to 0.
Enable or disable displaying the clock in the status bar. Disable by setting to 0 so a custom clock could be used in the
Display the number of iconic (minimized) windows in the status bar. Enable by setting to 1.
Border color of the currently focused window. Default is red.
Border color of the currently focused, maximized window. Defaults to the value of
Border color of unfocused windows, default is rgb:88/88/88.
Border color of unfocused, maximized windows. Defaults to the value of
Some applications have dialogue windows that are too small to be useful. This ratio is the screen size to what they will be resized. For example, 0.6 is 60% of the physical screen size.
Remove border when bar is disabled and there is only one window on the region.
Window to put focus when the focused window is closed. Possible values are first, next, previous (default) and last. next and previous are relative to the window that is closed.
Whether to allow the focus to jump to the last window when the first window is closed or vice versa. Disable by setting to 0.
Window to put focus when no window has been focused. Possible values are first and last (default).
Window focus behavior with respect to the pointer. Possible values:
Set window focus on border crossings caused by cursor motion and window interaction.
Set window focus on all cursor border crossings, including workspace switches and changes to layout.
Set window focus on window interaction only.
When set to 1,
maximize_togglewill also hide/restore the bar visibility of the affected workspace. Defaults to 0.
Clear all key bindings (not button bindings) and load new bindings from the specified file. This allows you to load pre-defined key bindings for your keyboard layout. See the Keyboard Mapping Files section below for a list of keyboard mapping files that have been provided for several keyboard layouts.
Select layout to use at start-of-day. Defined in the format
ws[idx]:master_grow:master_add:stack_inc:always_raise:stack_mode, e.g. ws:-4:0:1:0:horizontal sets worskspace 2 to the horizontal stack mode, shrinks the master area by 4 ticks and adds one window to the stack, while maintaining default floating window behavior. Possible stack_mode values are vertical, vertical_flip, horizontal, horizontal_flip and max.
always_raisefor more information. Note that the stacking options are complicated and have side-effects. One should familiarize oneself with these commands before experimenting with the
This setting is not retained at restart.
Change mod key. Mod1 is generally the ALT key and Mod4 is the windows key on a PC.
Set the name of a workspace at start-of-day. Defined in the format
ws[idx]:name, e.g. ws:Console sets the name of workspace 1 to “Console”.
Define new action to spawn a program p. See the Programs section below.
Add "quirk" for windows with class c, instance i (optional) and name n (optional). See the Quirks section below.
Allocates a custom region, removing any autodetected regions which occupy the same space on the screen. Defined in the format
screen[idx]:widthxheight+x+y, e.g. screen:800x1200+0+0.
To make a region span multiple monitors, create a region big enough to cover them all, e.g. screen:2048x768+0+0 makes the region span two monitors with 1024x768 resolution sitting one next to the other.
Pixel width of empty space within region borders. Disable by setting to 0.
Position in stack to place newly spawned windows. Possible values are first, next, previous and last (default). next and previous are relative to the focused window.
Enable or disable displaying the current stacking algorithm in the status bar.
Set a preferred minimum width for the terminal. If this value is greater than 0, spectrwm will attempt to adjust the font sizes in the terminal to keep the terminal width above this number as the window is resized. Only xterm(1) is currently supported. The xterm(1) binary must not be setuid or setgid, which it is by default on most systems. Users may need to set program[term] (see the Programs section) to use an alternate copy of the xterm(1) binary without the setgid bit set.
Pixel width of empty space between tiled windows. Negative values cause overlap. Set this to the opposite of
border_widthto collapse the border between tiles. Disable by setting to 0.
Minimizes the space consumed by the urgency hint indicator by removing the placeholders for non-urgent workspaces, the trailing space when there are urgent windows and the default leading space. Enable by setting to 1.
Enable or disable the urgency hint indicator in the status bar. Note that many terminal emulators require an explicit setting for the bell character to trigger urgency on the window. In xterm(1), for example, one needs to add the following line to
Enable or disable displaying the current master window count and stack column/row count in the status bar. Enable by setting to 1. See master_add, master_del, stack_inc and stack_dec for more information.
Prevents workspaces from being swapped when attempting to switch to a workspace that is mapped to another region. Use warp_focus if you want to focus on the region containing the workspace and warp_pointer if you want to also send the pointer. Enable by setting to 1.
Enable or disable displaying the window class name (from WM_CLASS) in the status bar. Enable by setting to 1.
Enable or disable displaying the window instance name (from WM_CLASS) in the status bar. Enable by setting to 1.
Enable or disable displaying the window display name (from _NET_WM_NAME/WM_NAME) in the status bar. Enable by setting to 1.
To prevent excessively large window names from pushing the remaining text off the bar, it's limited to 64 characters, by default. See the
bar_formatoption for more details.
Focus on the target window/workspace/region when clamped. For example, when attempting to switch to a workspace that is mapped on another region and workspace_clamp is enabled, focus on the region with the target workspace. Enable by setting to 1.
Centers the pointer on the focused window when using bindings to change focus, switch workspaces, change regions, etc. Enable by setting to 1.
Configure the status bar workspace indicator. One or more of the following options may be specified in a comma-separated list:
Include the current workspace.
Include workspaces with windows.
Include empty workspaces.
Include named workspaces.
Include workspaces with urgent window(s).
Include all workspaces.
Always exclude the current workspace from the list.
Indicate the current workspace if it is in the list.
Indicate workspaces in the list that contain urgent window(s).
Display the names of named workspaces in the list.
The default is listcurrent,listactive,markcurrent,printnames
Set the total number of workspaces available. Minimum is 1, maximum is 22, default is 10.
spectrwm allows you to define custom actions to launch programs of your choice and then bind them the same as with built-in actions. See the Bindings section below.
Custom programs in the configuration file are specified as follows:
program[action] = progpath [arg [arg ...]]
action is any identifier that does not conflict with a built-in action or keyword, progpath is the desired program, and arg is zero or more arguments to the program.
Remember that when using ‘
#’ in your program call, it must be escaped with a backslash, i.e. \#
The following argument variables will be substituted for values at the time the program is spawned:
program[ff] = /usr/local/bin/firefox http://spectrwm.org/ bind[ff] = MOD+Shift+b # Now M-S-b launches firefox
To cancel the previous, unbind it:
bind = MOD+Shift+b
dmenu_run $dmenu_bottom -fn $bar_font -nb $bar_color -nf $bar_font_color -sb $bar_color_selected -sf $bar_font_color_selected
dmenu $dmenu_bottom -i -fn $bar_font -nb $bar_color -nf $bar_font_color -sb $bar_color_selected -sf $bar_font_color_selected
dmenu $dmenu_bottom -p Workspace -fn $bar_font -nb $bar_color -nf $bar_font_color -sb $bar_color_selected -sf $bar_font_color_selected
initscreen.sh # optional
screenshot.sh full # optional
screenshot.sh window # optional
Note that optional default programs will not be validated unless overridden. If a default program fails validation, you can resolve the exception by installing the program, modifying the program call or disabling the program by freeing the respective binding.
For example, to override
program[lock] = xscreensaver-command -lock
lock and prevent it from being validated:
bind = MOD+Shift+Delete

Custom bindings in the configuration file are specified as follows:
bind[action] = combo
action is one of the actions listed above (or empty to unbind) and combo is in the form of zero or more modifier keys and/or special arguments (Mod1, Shift, MOD, etc.) and a normal key (b, Space, etc) or a button (Button1 .. Button255), separated by ‘
+’. Multiple key/button combinations may be bound to the same action.
Substituted for the currently defined
Select all modifier combinations not handled by another binding.
Reprocess binding press/release events for other programs to handle. Unavailable for
bind[reset] = Mod4+q # bind Windows-key + q to reset bind = Mod1+q # unbind Alt + q bind[move] = MOD+Button3 # Bind move to M-Button3 bind = MOD+Button1 # Unbind default move binding.
bind[focus] = ANYMOD+Button3 bind[move] = MOD+Button3
In the above example,
move and ⟨
Button3⟩ pressed with any other combination of modifiers sets focus to the window/region under the pointer.
bind[focus] = REPLAY+Button3
In the above example, when ⟨
Button3⟩ is pressed without any modifier(s), focus is set to the window under the pointer and the button press is passed to the window.
To bind non-latin characters such as å or π you must enter the xkb character name instead of the character itself. Run xev(1), focus the window and press the specific key and in the terminal output read the symbol name. In the following example for å:
KeyPress event, serial 41, synthetic NO, window 0x2600001, root 0x15a, subw 0x0, time 106213808, (11,5), root:(359,823), state 0x0, keycode 24 (keysym 0xe5, aring), same_screen YES, XLookupString gives 2 bytes: (c3 a5) "å" XmbLookupString gives 2 bytes: (c3 a5) "å" XFilterEvent returns: False
The xkb name is aring. In other words, in
bind[program] = MOD+aring
Keyboard Mapping Files
Keyboard mapping files for several keyboard layouts are listed below. These files can be used with the
keyboard_mapping setting to load pre-defined key bindings for the specified keyboard layout.
Czech Republic keyboard layout
Spanish keyboard layout
French keyboard layout
Swiss French keyboard layout
Swedish keyboard layout
United States keyboard layout
spectrwm provides "quirks" which handle windows that must be treated specially in a tiling window manager, such as some dialogs and fullscreen apps.
The default quirks are described below:
FLOAT + ANYWHERE
FLOAT + FULLSCREEN + FOCUSPREV
- OpenOffice.org 2.4:VCLSalFrame
- OpenOffice.org 3.1:VCLSalFrame
- xine:Xine Window
FLOAT + ANYWHERE
- xine:xine Panel
FLOAT + ANYWHERE
- xine:xine Video Fullscreen Window
FULLSCREEN + FLOAT
- Xitk:Xitk Combo
FLOAT + ANYWHERE
- Xitk:Xine Window
FLOAT + ANYWHERE
The quirks themselves are described below:
Allow window to position itself, uncentered.
This window should not be tiled, but allowed to float freely.
When the window first appears on the screen, change focus to the window if there are no other windows on the workspace with the same WM_CLASS class/instance value. Has no effect when
focus_modeis set to follow.
On exit force focus on previously focused application not previous application in the stack.
Remove border to allow window to use full region size.
Ignore the PID when determining the initial workspace for a new window. Especially useful for terminal windows that share a process.
Ignore the spawn workspace when determining the initial workspace for a new window.
Remove border when window is unfocused and floating.
Remove from normal focus cycle (focus_prev or focus_next). The window can still be focused using search_win.
Don't change focus to the window when it first appears on the screen. Has no effect when
focus_modeis set to follow.
When an application requests focus on the window via a _NET_ACTIVE_WINDOW client message (source indication of 1), comply with the request. Note that a source indication of 0 (unspecified) or 2 (pager) are always obeyed.
Adjusts size on transient windows that are too small using
dialog_ratio(see Configuration Files).
Force a new window to appear on workspace n.
Adjust xterm(1) fonts when resizing.
Custom quirks in the configuration file are specified as follows:
quirk[class[:instance[:name]]] = quirk [+ quirk ...]
class, instance (optional) and name (optional) are patterns used to determine which window(s) the quirk(s) apply to and quirk is one of the quirks from the list above.
Note that patterns are interpreted as POSIX Extended Regular Expressions. Any ':', '[' or ']' must be escaped with '\'. See regex(7) for more information on POSIX Extended Regular Expressions.
quirk[MPlayer] = FLOAT + FULLSCREEN + FOCUSPREV # Float all windows having a class of 'MPlayer' quirk[.*] = FLOAT # Float all windows by default. quirk[.*:.*:.*] = FLOAT # Same as above. quirk[Firefox:Navigator] = FLOAT # Float all Firefox browser windows. quirk[::Console] = FLOAT # Float windows with WM_CLASS not set and a window name of 'Console'. quirk[\[0-9\].*:.*:\[\[\:alnum\:\]\]*] = FLOAT # Float windows with WM_CLASS class beginning with a number, any WM_CLASS instance and a _NET_WM_NAME/WM_NAME either blank or containing alphanumeric characters without spaces. quirk[pcb:pcb] = NONE # remove existing quirk
You can obtain class, instance and name by running xprop(1) and then clicking on the desired window. In the following example the main window of Firefox was clicked:
$ xprop | grep -E "^(WM_CLASS|_NET_WM_NAME|WM_NAME)" WM_CLASS(STRING) = "Navigator", "Firefox" WM_NAME(STRING) = "spectrwm - ConformalOpenSource" _NET_WM_NAME(UTF8_STRING) = "spectrwm - ConformalOpenSource"
Note that xprop(1) displays WM_CLASS as:
WM_CLASS(STRING) = "<instance>", "<class>"
In the example above the quirk entry would be:
quirk[Firefox:Navigator] = FLOAT
spectrwm also automatically assigns quirks to windows based on the value of the window's _NET_WM_WINDOW_TYPE property as follows:
FLOAT + ANYWHERE
FLOAT + ANYWHERE
FLOAT + ANYWHERE
In all other cases, no automatic quirks are assigned to the window. Quirks specified in the configuration file override the automatic quirks.
spectrwm partially implements the Extended Window Manager Hints (EWMH) specification. This enables controlling windows as well as spectrwm itself from external scripts and programs. This is achieved by spectrwm responding to certain ClientMessage events. From the terminal these events can be conveniently sent using tools such as wmctrl(1) and xdotool(1). For the actual format of these ClientMessage events, see the EWMH specification.
The id of the currently focused window is stored in the _NET_ACTIVE_WINDOW property of the root window. This can be used for example to retrieve the title of the currently active window with xprop(1) and grep(1):
$ WINDOWID=`xprop -root _NET_ACTIVE_WINDOW | grep -o "0x.*"` $ xprop -id $WINDOWID _NET_WM_NAME | grep -o "\".*\""
A window can be focused by sending a _NET_ACTIVE_WINDOW client message to the root window. For example, using wmctrl(1) to send the message (assuming 0x4a0000b is the id of the window to be focused):
$ wmctrl -i -a 0x4a0000b
Windows can be closed by sending a _NET_CLOSE_WINDOW client message to the root window. For example, using wmctrl(1) to send the message (assuming 0x4a0000b is the id of the window to be closed):
$ wmctrl -i -c 0x4a0000b
Windows can be floated and un-floated by adding or removing the _NET_WM_STATE_ABOVE atom from the _NET_WM_STATE property of the window. This can be achieved by sending a _NET_WM_STATE client message to the root window. For example, the following toggles the floating state of a window using wmctrl(1) to send the message (assuming 0x4a0000b is the id of the window to be floated or un-floated):
$ wmctrl -i -r 0x4a0000b -b toggle,_NET_WM_STATE_ABOVE
Windows can also be iconified and un-iconified by substituting _NET_WM_STATE_HIDDEN for _NET_WM_STATE_ABOVE in the previous example:
$ wmctrl -i -r 0x4a0000b -b toggle,_NET_WM_STATE_HIDDEN
Floating windows can also be resized and moved by sending a _NET_MOVERESIZE_WINDOW client message to the root window. For example, using wmctrl(1) to send the message (assuming 0x4a0000b is the id of the window to be resize/moved):
$ wmctrl -i -r 0x4a0000b -e 0,100,50,640,480
This moves the window to (100,50) and resizes it to 640x480.
Any _NET_MOVERESIZE_WINDOW events received for stacked windows are ignored.
Sending spectrwm a HUP signal will restart it.
