+dwm - dynamic window manager
+============================
+dwm is an extremely fast, small, and dynamic window manager for X.
+
+
+Requirements
+------------
+In order to build dwm you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (dwm is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install dwm (if
+necessary as root):
+
+ make clean install
+
+
+Running dwm
+-----------
+Add the following line to your .xinitrc to start dwm using startx:
+
+ exec dwm
+
+In order to connect dwm to a specific display, make sure that
+the DISPLAY environment variable is set correctly, e.g.:
+
+ DISPLAY=foo.bar:1 exec dwm
+
+(This will start dwm on display :1 of the host foo.bar.)
+
+In order to display status info in the bar, you can do something
+like this in your .xinitrc:
+
+ while xsetroot -name "`date` `uptime | sed 's/.*,//'`"
+ do
+ sleep 1
+ done &
+ exec dwm
+
+
+Configuration
+-------------
+The configuration of dwm is done by creating a custom config.h
+and (re)compiling the source code.

+.SH NAME
+dwm \- dynamic window manager
+.SH SYNOPSIS
+.B dwm
+.RB [ \-v ]
+.SH DESCRIPTION
+dwm is a dynamic window manager for X. It manages windows in tiled, monocle
+and floating layouts. Either layout can be applied dynamically, optimising the
+environment for the application in use and the task performed.
+.P
+In tiled layouts windows are managed in a master and stacking area. The master
+area on the left contains one window by default, and the stacking area on the
+right contains all other windows. The number of master area windows can be
+adjusted from zero to an arbitrary number. In monocle layout all windows are
+maximised to the screen size. In floating layout windows can be resized and
+moved freely. Dialog windows are always managed floating, regardless of the
+layout applied.
+.P
+Windows are grouped by tags. Each window can be tagged with one or multiple
+tags. Selecting certain tags displays all windows with these tags.
+.P
+Each screen contains a small status bar which displays all available tags, the
+layout, the title of the focused window, and the text read from the root window
+name property, if the screen is focused. A floating window is indicated with an
+empty square and a maximised floating window is indicated with a filled square
+before the windows title. The selected tags are indicated with a different
+color. The tags of the focused window are indicated with a filled square in the
+top left corner. The tags which are applied to one or more windows are
+indicated with an empty square in the top left corner.
+.P
+dwm draws a small border around windows to indicate the focus state.
+.SH OPTIONS
+.TP
+.B \-v
+prints version information to stderr, then exits.
+.SH USAGE
+.SS Status bar
+.TP
+.B X root window name
+is read and displayed in the status text area. It can be set with the
+.BR xsetroot (1)
+command.
+.TP
+.B Button1
+click on a tag label to display all windows with that tag, click on the layout
+label toggles between tiled and floating layout.
+.TP
+.B Button3
+click on a tag label adds/removes all windows with that tag to/from the view.
+.TP
+.B Mod1\-Button1
+click on a tag label applies that tag to the focused window.
+.TP
+.B Mod1\-Button3
+click on a tag label adds/removes that tag to/from the focused window.

+.SH ISSUES
+Java applications which use the XToolkit/XAWT backend may draw grey windows
+only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early
+JDK 1.6 versions, because it assumes a reparenting window manager. Possible workarounds
+are using JDK 1.4 (which doesn't contain the XToolkit/XAWT backend) or setting the
+environment variable
+.BR AWT_TOOLKIT=MToolkit
+(to use the older Motif backend instead) or running
+.B xprop -root -f _NET_WM_NAME 32a -set _NET_WM_NAME LG3D
+or
+.B wmname LG3D
+(to pretend that a non-reparenting window manager is running that the
+XToolkit/XAWT backend can recognize) or when using OpenJDK setting the environment variable
+.BR _JAVA_AWT_WM_NONREPARENTING=1 .

+/* See LICENSE file for copyright and license details.
+ *
+ * dynamic window manager is designed like any other X client as well. It is
+ * driven through handling X events. In contrast to other X clients, a window
+ * manager selects for SubstructureRedirectMask on the root window, to receive
+ * events about window (dis-)appearance. Only one X connection at a time is
+ * allowed to select for this event mask.
+ *
+ * The event handlers of dwm are organized in an array which is accessed
+ * whenever a new event has been fetched. This allows event dispatching
+ * in O(1) time.
+ *
+ * Each child of the root window is called a client, except windows which have
+ * set the override_redirect flag. Clients are organized in a linked client
+ * list on each monitor, the focus history is remembered through a stack list
+ * on each monitor. Each client contains a bit array to indicate the tags of a
+ * client.
+ *
+ * Keys and tagging rules are organized as arrays and defined in config.h.
+ *
+ * To understand everything else, start reading main().

+slstatus - suckless status
+==========================
+slstatus is a small tool for providing system status information to other
+programs over the EWMH property of the root window (used by dwm(1)) or
+standard input/output. It is designed to be as efficient as possible by
+only issuing the minimum of system calls required.
+
+
+Features
+--------
+- Battery percentage/state/time left
+- Cat (read file)
+- CPU usage
+- CPU frequency
+- Custom shell commands
+- Date and time
+- Disk status (free storage, percentage, total storage and used storage)
+- Available entropy
+- Username/GID/UID
+- Hostname
+- IP address (IPv4 and IPv6)
+- Kernel version
+- Keyboard indicators
+- Keymap
+- Load average
+- Network speeds (RX and TX)
+- Number of files in a directory (hint: Maildir)
+- Memory status (free memory, percentage, total memory and used memory)
+- Swap status (free swap, percentage, total swap and used swap)
+- Temperature
+- Uptime
+- Volume percentage
+- WiFi signal percentage and ESSID
+
+
+Requirements
+------------
+Currently slstatus works on FreeBSD, Linux and OpenBSD.
+In order to build slstatus you need the Xlib header files.
+
+- For volume percentage on Linux the kernel module `snd-mixer-oss` must be
+ loaded.
+- For volume percentage on FreeBSD, `sndio` must be installed.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (slstatus is installed into the
+/usr/local namespace by default).
+
+Afterwards enter the following command to build and install slstatus (if
+necessary as root):
+
+ make clean install
+
+
+Running slstatus
+----------------
+See the man page for details.
+
+
+Configuration
+-------------
+slstatus can be customized by creating a custom config.h and (re)compiling the
+source code. This keeps it fast, secure and simple.

+.Nm
+.Op Fl s
+.Op Fl 1
+.Sh DESCRIPTION
+.Nm
+is a small tool for providing system status information to other programs
+over the EWMH
+.Em WM_NAME
+property of the root window (used by
+.Xr dwm 1 ) or standard input/output. It is designed to be as efficient as possible by
+only issuing the minimum of system calls required.
+.P
+By default,
+.Nm
+outputs to WM_NAME.
+.Sh OPTIONS
+.Bl -tag -width Ds
+.It Fl v
+Print version information to stderr, then exit.
+.It Fl s
+Write to stdout instead of WM_NAME.
+.It Fl 1
+Write once to stdout and quit.
+.El
+.Sh CUSTOMIZATION
+.Nm
+can be customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.Sh SIGNALS
+.Nm
+responds to the following signals:
+.Pp
+.Bl -tag -width TERM -compact
+.It USR1
+Triggers an instant redraw.

+++ st/FAQ
+## Why does st not handle utmp entries?
+
+Use the excellent tool of [utmp](https://git.suckless.org/utmp/) for this task.
+
+
+## Some _random program_ complains that st is unknown/not recognised/unsupported/whatever!
+
+It means that st doesn’t have any terminfo entry on your system. Chances are
+you did not `make install`. If you just want to test it without installing it,
+you can manually run `tic -sx st.info`.
+
+
+## Nothing works, and nothing is said about an unknown terminal!
+
+* Some programs just assume they’re running in xterm i.e. they don’t rely on
+ terminfo. What you see is the current state of the “xterm compliance”.
+* Some programs don’t complain about the lacking st description and default to
+ another terminal. In that case see the question about terminfo.
+
+
+## How do I scroll back up?
+
+* Using a terminal multiplexer.
+ * `st -e tmux` using C-b [
+ * `st -e screen` using C-a ESC
+* Using the excellent tool of [scroll](https://git.suckless.org/scroll/).
+* Using the scrollback [patch](https://st.suckless.org/patches/scrollback/).
+
+
+## I would like to have utmp and/or scroll functionality by default
+
+You can add the absolute path of both programs in your config.h file. You only
+have to modify the value of utmp and scroll variables.
+
+
+## Why doesn't the Del key work in some programs?
+
+Taken from the terminfo manpage:
+
+ If the terminal has a keypad that transmits codes when the keys
+ are pressed, this information can be given. Note that it is not
+ possible to handle terminals where the keypad only works in
+ local (this applies, for example, to the unshifted HP 2621 keys).
+ If the keypad can be set to transmit or not transmit, give these
+ codes as smkx and rmkx. Otherwise the keypad is assumed to
+ always transmit.
+
+In the st case smkx=E[?1hE= and rmkx=E[?1lE>, so it is mandatory that
+applications which want to test against keypad keys send these
+sequences.
+
+But buggy applications (like bash and irssi, for example) don't do this. A fast
+solution for them is to use the following command:
+
+ $ printf '\033[?1h\033=' >/dev/tty
+
+or
+ $ tput smkx
+
+In the case of bash, readline is used. Readline has a different note in its
+manpage about this issue:
+
+ enable-keypad (Off)
+ When set to On, readline will try to enable the
+ application keypad when it is called. Some systems
+ need this to enable arrow keys.
+
+Adding this option to your .inputrc will fix the keypad problem for all
+applications using readline.
+
+If you are using zsh, then read the zsh FAQ
+<http://zsh.sourceforge.net/FAQ/zshfaq03.html#l25>:
+
+ It should be noted that the O / [ confusion can occur with other keys
+ such as Home and End. Some systems let you query the key sequences
+ sent by these keys from the system's terminal database, terminfo.
+ Unfortunately, the key sequences given there typically apply to the
+ mode that is not the one zsh uses by default (it's the "application"
+ mode rather than the "raw" mode). Explaining the use of terminfo is
+ outside of the scope of this FAQ, but if you wish to use the key
+ sequences given there you can tell the line editor to turn on
+ "application" mode when it starts and turn it off when it stops:
+
+ function zle-line-init () { echoti smkx }
+ function zle-line-finish () { echoti rmkx }
+ zle -N zle-line-init
+ zle -N zle-line-finish
+
+Putting these lines into your .zshrc will fix the problems.
+
+
+## How can I use meta in 8bit mode?
+
+St supports meta in 8bit mode, but the default terminfo entry doesn't
+use this capability. If you want it, you have to use the 'st-meta' value
+in TERM.
+
+
+## I cannot compile st in OpenBSD
+
+OpenBSD lacks librt, despite it being mandatory in POSIX
+<http://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html#tag_20_11_13>.
+If you want to compile st for OpenBSD you have to remove -lrt from config.mk, and
+st will compile without any loss of functionality, because all the functions are
+included in libc on this platform.
+
+
+## The Backspace Case
+
+St is emulating the Linux way of handling backspace being delete and delete being
+backspace.
+
+This is an issue that was discussed in suckless mailing list
+<https://lists.suckless.org/dev/1404/20697.html>. Here is why some old grumpy
+terminal users wants its backspace to be how he feels it:
+
+ Well, I am going to comment why I want to change the behaviour
+ of this key. When ASCII was defined in 1968, communication
+ with computers was done using punched cards, or hardcopy
+ terminals (basically a typewriter machine connected with the
+ computer using a serial port). ASCII defines DELETE as 7F,
+ because, in punched-card terms, it means all the holes of the
+ card punched; it is thus a kind of 'physical delete'. In the
+ same way, the BACKSPACE key was a non-destructive backspace,
+ as on a typewriter. So, if you wanted to delete a character,
+ you had to BACKSPACE and then DELETE. Another use of BACKSPACE
+ was to type accented characters, for example 'a BACKSPACE `'.
+ The VT100 had no BACKSPACE key; it was generated using the
+ CONTROL key as another control character (CONTROL key sets to
+ 0 b7 b6 b5, so it converts H (code 0x48) into BACKSPACE (code
+ 0x08)), but it had a DELETE key in a similar position where
+ the BACKSPACE key is located today on common PC keyboards.
+ All the terminal emulators emulated the difference between
+ these keys correctly: the backspace key generated a BACKSPACE
+ (^H) and delete key generated a DELETE (^?).
+
+ But a problem arose when Linus Torvalds wrote Linux. Unlike
+ earlier terminals, the Linux virtual terminal (the terminal
+ emulator integrated in the kernel) returned a DELETE when
+ backspace was pressed, due to the VT100 having a DELETE key in
+ the same position. This created a lot of problems (see [1]
+ and [2]). Since Linux has become the king, a lot of terminal
+ emulators today generate a DELETE when the backspace key is
+ pressed in order to avoid problems with Linux. The result is
+ that the only way of generating a BACKSPACE on these systems
+ is by using CONTROL + H. (I also think that emacs had an
+ important point here because the CONTROL + H prefix is used
+ in emacs in some commands (help commands).)
+
+ From point of view of the kernel, you can change the key
+ for deleting a previous character with stty erase. When you
+ connect a real terminal into a machine you describe the type
+ of terminal, so getty configures the correct value of stty
+ erase for this terminal. In the case of terminal emulators,
+ however, you don't have any getty that can set the correct
+ value of stty erase, so you always get the default value.
+ For this reason, it is necessary to add 'stty erase ^H' to your
+ profile if you have changed the value of the backspace key.
+ Of course, another solution is for st itself to modify the
+ value of stty erase. I usually have the inverse problem:
+ when I connect to non-Unix machines, I have to press CONTROL +
+ h to get a BACKSPACE. The inverse problem occurs when a user
+ connects to my Unix machines from a different system with a
+ correct backspace key.

+## Why do images not work in st using the w3m image hack?
+
+w3mimg uses a hack that draws an image on top of the terminal emulator Drawable
+window. The hack relies on the terminal to use a single buffer to draw its
+contents directly.
+
+st uses double-buffered drawing so the image is quickly replaced and may show a
+short flicker effect.
+
+Below is a patch example to change st double-buffering to a single Drawable
+buffer.

+## BadLength X error in Xft when trying to render emoji
+
+Xft makes st crash when rendering color emojis with the following error:
+
+"X Error of failed request: BadLength (poly request too large or internal Xlib length error)"
+ Major opcode of failed request: 139 (RENDER)
+ Minor opcode of failed request: 20 (RenderAddGlyphs)
+ Serial number of failed request: 1595
+ Current serial number in output stream: 1818"
+
+This is a known bug in Xft (not st) which happens on some platforms and
+combination of particular fonts and fontconfig settings.
+
+See also:
+https://gitlab.freedesktop.org/xorg/lib/libxft/issues/6
+https://bugs.freedesktop.org/show_bug.cgi?id=107534
+https://bugzilla.redhat.com/show_bug.cgi?id=1498269
+
+The solution is to remove color emoji fonts or disable this in the fontconfig
+XML configuration. As an ugly workaround (which may work only on newer
+fontconfig versions (FC_COLOR)), the following code can be used to mask color
+fonts:
+
+ FcPatternAddBool(fcpattern, FC_COLOR, FcFalse);
+
+Please don't bother reporting this bug to st, but notify the upstream Xft
+developers about fixing this bug.
+
+As of 2022-09-05 this now seems to be finally fixed in libXft 2.3.5:
+https://gitlab.freedesktop.org/xorg/lib/libxft/-/blob/libXft-2.3.5/NEWS

+A STATEMENT ON LEGACY SUPPORT
+
+In the terminal world there is much cruft that comes from old and unsup‐
+ported terminals that inherit incompatible modes and escape sequences
+which noone is able to know, except when he/she comes from that time and
+developed a graphical vt100 emulator at that time.
+
+One goal of st is to only support what is really needed. When you en‐
+counter a sequence which you really need, implement it. But while you
+are at it, do not add the other cruft you might encounter while sneek‐
+ing at other terminal emulators. History has bloated them and there is
+no real evidence that most of the sequences are used today.

+
+Afterwards enter the following command to build and install st (if
+necessary as root):
+
+ make clean install
+
+
+Running st
+----------
+If you did not install st with make clean install, you must compile

+.SH DESCRIPTION
+.B st
+is a simple terminal emulator.
+.SH OPTIONS
+.TP
+.B \-a
+disable alternate screens in terminal
+.TP
+.BI \-c " class"
+defines the window class (default $TERM).
+.TP
+.BI \-f " font"
+defines the
+.I font
+to use when st is run.
+.TP
+.BI \-g " geometry"
+defines the X11 geometry string.
+The form is [=][<cols>{xX}<rows>][{+-}<xoffset>{+-}<yoffset>]. See
+.BR XParseGeometry (3)
+for further details.
+.TP
+.B \-i
+will fixate the position given with the -g option.
+.TP
+.BI \-n " name"
+defines the window instance name (default $TERM).
+.TP
+.BI \-o " iofile"
+writes all the I/O to
+.I iofile.
+This feature is useful when recording st sessions. A value of "-" means
+standard output.
+.TP
+.BI \-T " title"
+defines the window title (default 'st').
+.TP
+.BI \-t " title"
+defines the window title (default 'st').
+.TP
+.BI \-w " windowid"
+embeds st within the window identified by
+.I windowid
+.TP
+.BI \-l " line"
+use a tty
+.I line
+instead of a pseudo terminal.
+.I line
+should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port
+0).
+When this flag is given
+remaining arguments are used as flags for
+.BR stty(1).
+By default st initializes the serial line to 8 bits, no parity, 1 stop bit
+and a 38400 baud rate. The speed is set by appending it as last argument
+(e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are
+.BR stty(1)
+flags. If you want to set odd parity on 115200 baud use for example 'st -l
+/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for
+example 'st -l /dev/ttyS0 cs7 115200'. See
+.BR stty(1)
+for more arguments and cases.
+.TP
+.B \-v
+prints version information to stderr, then exits.
+.TP
+.BI \-e " command " [ " arguments " "... ]"
+st executes
+.I command
+instead of the shell. If this is used it
+.B must be the last option
+on the command line, as in xterm / rxvt.
+This option is only intended for compatibility,
+and all the remaining arguments are used as a command
+even without it.
+.SH SHORTCUTS
+.TP
+.B Break
+Send a break in the serial line.
+Break key is obtained in PC keyboards
+pressing at the same time control and pause.
+.TP
+.B Ctrl-Print Screen
+Toggle if st should print to the
+.I iofile.
+.TP
+.B Shift-Print Screen
+Print the full screen to the
+.I iofile.
+.TP
+.B Print Screen
+Print the selection to the
+.I iofile.
+.TP
+.B Ctrl-Shift-Page Up
+Increase font size.
+.TP
+.B Ctrl-Shift-Page Down
+Decrease font size.
+.TP
+.B Ctrl-Shift-Home
+Reset to default font size.
+.TP
+.B Ctrl-Shift-y
+Paste from primary selection (middle mouse button).
+.TP
+.B Ctrl-Shift-c
+Copy the selected text to the clipboard selection.
+.TP
+.B Ctrl-Shift-v
+Paste from the clipboard selection.
+.SH CUSTOMIZATION
+.B st
+can be customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH AUTHORS
+See the LICENSE file for the authors.
+.SH LICENSE
+See the LICENSE file for the terms of redistribution.
+.SH SEE ALSO
+.BR tabbed (1),
+.BR utmp (1),
+.BR stty (1),
