  20 .Nm scrotwm
  21 .Nd window manager for X11
  22 .Sh SYNOPSIS
  23 .Nm scrotwm
  24 .Sh DESCRIPTION
  25 .Nm
  26 is a minimalistic window manager that tries to stay out of the way so that
  27 valuable screen real estate can be used for much more important stuff.
  28 It has sane defaults and does not require one to learn a language to do any
  29 configuration.
  30 It was written by hackers for hackers and it strives to be small, compact and
  31 fast.
  32 .Pp
  33 When
  34 .Nm
  35 starts up, it reads settings from its configuration file,
  36 .Pa scrotwm.conf .
  37 See the
  38 .Sx CONFIGURATION FILES
  39 section below.
  40 .Pp
  41 The following notation is used throughout this page:
  42 .Pp
  43 .Bl -tag -width Ds -offset indent -compact
  44 .It Cm M
  45 Meta
  46 .It Cm S
  47 Shift
  48 .It Aq Cm Name
  49 Named key

  51 Mouse button 1
  52 .It Cm M3
  53 Mouse button 3
  54 .El
  55 .Pp
  56 .Nm
  57 is very simple in its use.
  58 Most of the actions are initiated via key or mouse bindings.
  59 See the
  60 .Sx BINDINGS
  61 section below for defaults and customizations.
  62 .Sh CONFIGURATION FILES
  63 .Nm
  64 first tries to open the user specific file,
  65 .Pa ~/.scrotwm.conf .
  66 If that file is unavailable,
  67 it then tries to open the global configuration file
  68 .Pa /etc/scrotwm.conf .
  69 .Pp
  70 The format of the file is \*(Ltkeyword\*(Gt = \*(Ltsetting\*(Gt.
  71 For example:
  72 .Pp
  73 .Dl color_focus = red
  74 .Pp
  75 Enabling or disabling an option is done by using 1 or 0 respectively.
  76 .Pp
  77 The file supports the following keywords:
  78 .Pp
  79 .Bl -tag -width "title_class_enabledXXX" -offset indent -compact
  80 .It Cm autorun
  81 Launch an application in a specified workspace at start-of-day.
  82 Defined in the format ws[<idx>]:application, e.g. ws[2]:xterm launches an
  83 xterm in workspace 2.
  84 .It Cm color_focus
  85 Border color of the currently focussed window.
  86 .It Cm color_unfocus
  87 Border color of unfocussed windows.
  88 .It Cm bar_enabled
  89 Enable or disable status bar.
  90 .It Cm bar_border Ns Bq Ar x
  91 Color of the status bar border in screen
  92 .Ar x .
  93 .It Cm bar_border_width
  94 Set status bar border thickness in pixels.
  95 Disable border by setting to 0.
  96 .It Cm bar_color Ns Bq Ar x
  97 Color of the status bar window in screen
  98 .Ar x .
  99 .It Cm bar_font_color Ns Bq Ar x
 100 Color of the font in status bar in screen
 101 .Ar x .
 102 .It Cm bar_font
 103 Status bar font.
 104 .It Cm bar_action
 105 External script that populates additional information in the status bar,
 106 such as battery life.
 107 .It Cm bar_delay
 108 Update frequency, in seconds, of external script that populates the status bar.
 109 .It Cm bar_at_bottom
 110 Place the statusbar at the bottom of each region instead of the top.
 111 .It Cm stack_enabled
 112 Enable or disable displaying the current stacking algorithm in the status bar.
 113 .It Cm clock_enabled
 114 Enable or disable displaying the clock in the status bar.
 115 Disable by setting to 0
 116 so a custom clock could be used in the
 117 .Pa bar_action
 118 script.
 119 .It Cm dialog_ratio
 120 Some applications have dialogue windows that are too small to be useful.
 121 This ratio is the screen size to what they will be resized.
 122 For example, 0.6 is 60% of the physical screen size.
 123 .It Cm layout
 124 Select layout to use at start-of-day.
 125 Defined in the format
 126 ws[idx]:master_grow:master_add:stack_inc:layout:always_raise:stack_mode, e.g.
 127 ws[2]:-4:0:1:0:horizontal sets worskspace 2 to the horizontal stack mode and
 128 shrinks the master area by 4 ticks and adds one window to the stack, while
 129 maintaining default floating window behavior.
 130 Possible stack_mode values are
 131 .Pa vertical ,
 132 .Pa horizontal
 133 and
 134 .Pa fullscreen .
 135 .Pp
 136 See
 137 .Pa master_grow ,
 138 .Pa master_shrink ,
 139 .Pa master_add ,
 140 .Pa master_del ,
 141 .Pa stack_inc ,
 142 .Pa stack_del ,
 143 and
 144 .Pa always_raise
 145 for more information.
 146 Note that the stacking options are complicated and have side-effects.
 147 One should familiarize oneself with these commands before experimenting with the
 148 .Pa layout
 149 option.
 150 .Pp
 151 This setting is not retained at restart.
 152 .It Cm region
 153 Allocates a custom region, removing any autodetected regions which occupy the same
 154 space on the screen.
 155 Defined in the format screen[<idx>]:WIDTHxHEIGHT+X+Y,
 156 e.g.\& screen[1]:800x1200+0+0.
 157 .Pp
 158 To make a screen span multiple monitors, create a region big enough to cover
 159 them all, e.g. screen[1]:2048x768+0+0 makes the screen span two monitors with
 160 1024x768 resolution sitting one next to the other.
 161 .It Cm term_width
 162 Set a preferred minimum width for the terminal.
 163 If this value is greater than 0,
 164 .Nm
 165 will attempt to adjust the font sizes in the terminal to keep the terminal
 166 width above this number as the window is resized.
 167 Only
 168 .Xr xterm 1
 169 is currently supported.
 170 The
 171 .Xr xterm 1
 172 binary must not be setuid or setgid, which it is by default on most systems.
 173 Users may need to set program[term] (see the
 174 .Sx PROGRAMS
 175 section) to use an alternate copy of the
 176 .Xr xterm 1
 177 binary without the setgid bit set.
 178 .It Cm title_class_enabled
 179 Enable or disable displaying the window class in the status bar.
 180 Enable by setting to 1.
 181 .It Cm title_name_enabled
 182 Enable or disable displaying the window title in the status bar.
 183 Enable by setting to 1.
 184 .It Cm urgent_enabled
 185 Enable or disable the urgency hint.
 186 Note that many terminal emulators require this to be enabled for it to
 187 propagate.  In xterm, for example, one needs to add the following line
 188 .Pa xterm.urgentOnBell: true
 189 to
 190 .Pa .Xdefaults .
 191 .It Cm window_name_enabled
 192 Enable or disable displaying the window name in the status bar.
 193 Enable by setting to 1.
 194 .It Cm verbose_layout
 195 Enable or disable displaying the current master and stack values in the status
 196 bar.
 197 Enable by setting to 1.
 198 .It Cm modkey
 199 Change mod key.
 200 Mod1 is generally the ALT key and Mod4 is the windows key on a PC.
 201 .It Cm focus_mode
 202 Using a value of
 203 .Pa follow_cursor
 204 will make the window manager focus the window
 205 under the mouse when switching workspaces and creating windows.
 206 .It Cm disable_border
 207 Remove border when bar is disabled and there is only one window on the screen.
 208 .It Cm border_width
 209 Set window border thickness in pixels.
 210 Disable all borders by setting to 0.

 651 and
 652 .Aq name
 653 by running xprop(1) and then clicking on the desired window.
 654 In the following example the main window of Firefox was clicked:
 655 .Bd -literal -offset indent
 656 $ xprop | grep WM_CLASS
 657 WM_CLASS(STRING) = "Navigator", "Firefox"
 658 .Ed
 659 .Pp
 660 Note that grepping for WM_CLASS flips class and name.
 661 In the example above the quirk entry would be:
 662 .Bd -literal -offset indent
 663 quirk[Firefox:Navigator] = FLOAT
 664 .Ed
 665 .Pp
 666 .Nm
 667 also automatically assigns quirks to windows based on the value
 668 of the window's _NET_WM_WINDOW_TYPE property as follows:
 669 .Pp
 670 .Bl -tag -width "_NET_WM_WINDOW_TYPE_TOOLBAR<TAB>XXX" -offset indent -compact
 671 .It _NET_WM_WINDOW_TYPE_DOCK
 672 FLOAT + ANYWHERE
 673 .It _NET_WM_WINDOW_TYPE_TOOLBAR
 674 FLOAT + ANYWHERE
 675 .It _NET_WM_WINDOW_TYPE_UTILITY
 676 FLOAT + ANYWHERE
 677 .It _NET_WM_WINDOW_TYPE_SPLASH
 678 FLOAT
 679 .It _NET_WM_WINDOW_TYPE_DIALOG
 680 FLOAT
 681 .El
 682 .Pp
 683 In all other cases, no automatic quirks are assigned to the window.
 684 Quirks specified in the configuration file override the automatic quirks.
 685 .Sh EWMH
 686 .Nm
 687 partially implements the Extended Window Manager Hints (EWMH) specification.
 688 This enables controlling windows as well as
 689 .Nm
 690 itself from external scripts and programs. This is achieved by
 691 .Nm
 692 responding to certain ClientMessage events. From the terminal these events
 693 can be conveniently sent using tools such as
 694 .Xr wmctrl 1
 695 and
 696 .Xr xdotool 1 .
 697 For the
 698 actual format of these ClientMessage events, see the EWMH specification.
 699 .Pp
 700 The id of the currently focused window is stored in the _NET_ACTIVE_WINDOW
 701 property of the root window. This can be used for example to retrieve the
 702 title of the currently active window with
 703 .Xr xprop 1
 704 and
 705 .Xr grep 1 :
 706 .Bd -literal -offset indent
 707 $ WINDOWID=`xprop \-root _NET_ACTIVE_WINDOW | grep \-o "0x.*"`
 708 $ xprop \-id $WINDOWID WM_NAME | grep \-o "\\".*\\""
 709 .Ed
 710 .Pp
 711 A window can be focused by sending a _NET_ACTIVE_WINDOW client message
 712 to the root window. For example, using
 713 .Xr wmctrl 1
 714 to send the message
 715 (assuming 0x4a0000b is the id of the window to be focused):
 716 .Bd -literal -offset indent
 717 $ wmctrl \-i \-a 0x4a0000b
 718 .Ed
 719 .Pp
 720 Windows can be closed by sending a _NET_CLOSE_WINDOW client message
 721 to the root window. For example, using
 722 .Xr wmctrl 1
 723 to send the message
 724 (assuming 0x4a0000b is the id of the window to be closed):
 725 .Bd -literal -offset indent
 726 $ wmctrl \-i \-c 0x4a0000b
 727 .Ed
 728 .Pp
 729 Windows can be floated and un-floated by adding or removing the
 730 _NET_WM_STATE_ABOVE atom from the _NET_WM_STATE property of the window.
 731 This can be achieved by sending a _NET_WM_STATE client message to the
 732 root window. For example, the following toggles the floating state of
 733 a window using
 734 .Xr wmctrl 1
 735 to send the message (assuming 0x4a0000b is the  id of the window floated
 736 or un-floated):
 737 .Bd -literal -offset indent
 738 $ wmctrl \-i \-r 0x4a0000b \-b toggle,_NET_WM_STATE_ABOVE
 739 .Ed
 740 .Pp
 741 Floating windows can also be resized and moved by sending a
 742 _NET_MOVERESIZE_WINDOW client message to the root window. For example,
 743 using
 744 .Xr wmctrl 1
 745 to send the message (assuming 0x4a0000b is the id of
 746 the window to be resize/moved):
 747 .Bd -literal -offset indent
 748 $ wmctrl \-i \-r 0x4a0000b \-e 0,100,50,640,480
 749 .Ed
 750 .Pp
 751 This moves the window to (100,50) and resizes it to 640x480.
 752 .Pp
 753 Any _NET_MOVERESIZE_WINDOW events received for stacked windows are ignored.
