+dmenu - dynamic menu
+====================
+dmenu is an efficient dynamic menu for X.
+
+
+Requirements
+------------
+In order to build dmenu you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (dmenu is installed into
+the /usr/local namespace by default).
+
+Afterwards enter the following command to build and install dmenu
+(if necessary as root):
+
+    make clean install
+
+
+Running dmenu
+-------------
+See the man page for details.

+.P
+.BR dmenu_run " ..."
+.SH DESCRIPTION
+.B dmenu
+is a dynamic menu for X, which reads a list of newline\-separated items from
+stdin.  When the user selects an item and presses Return, their choice is printed
+to stdout and dmenu terminates.  Entering text will narrow the items to those
+matching the tokens in the input.
+.P
+.B dmenu_run
+is a script used by
+.IR dwm (1)
+which lists programs in the user's $PATH and runs the result in their $SHELL.
+.SH OPTIONS
+.TP
+.B \-b
+dmenu appears at the bottom of the screen.
+.TP
+.B \-f
+dmenu grabs the keyboard before reading stdin if not reading from a tty. This
+is faster, but will lock up X until stdin reaches end\-of\-file.
+.TP
+.B \-i
+dmenu matches menu items case insensitively.
+.TP
+.BI \-l " lines"
+dmenu lists items vertically, with the given number of lines.
+.TP
+.BI \-m " monitor"
+dmenu is displayed on the monitor number supplied. Monitor numbers are starting
+from 0.
+.TP
+.BI \-p " prompt"
+defines the prompt to be displayed to the left of the input field.
+.TP
+.BI \-fn " font"
+defines the font or font set used.
+.TP
+.BI \-nb " color"
+defines the normal background color.
+.IR #RGB ,
+.IR #RRGGBB ,
+and X color names are supported.
+.TP
+.BI \-nf " color"
+defines the normal foreground color.
+.TP
+.BI \-sb " color"
+defines the selected background color.
+.TP
+.BI \-sf " color"
+defines the selected foreground color.
+.TP
+.B \-v
+prints version information to stdout, then exits.
+.TP
+.BI \-w " windowid"
+embed into windowid.
+.SH USAGE
+dmenu is completely controlled by the keyboard.  Items are selected using the
+arrow keys, page up, page down, home, and end.
+.TP
+.B Tab
+Copy the selected item to the input field.
+.TP
+.B Return
+Confirm selection.  Prints the selected item to stdout and exits, returning
+success.
+.TP
+.B Ctrl-Return
+Confirm selection.  Prints the selected item to stdout and continues.
+.TP
+.B Shift\-Return
+Confirm input.  Prints the input text to stdout and exits, returning success.
+.TP
+.B Escape
+Exit without selecting an item, returning failure.
+.TP
+.B Ctrl-Left
+Move cursor to the start of the current word
+.TP
+.B Ctrl-Right
+Move cursor to the end of the current word

+.TH STEST 1 dmenu\-VERSION
+.SH NAME
+stest \- filter a list of files by properties
+.SH SYNOPSIS
+.B stest
+.RB [ -abcdefghlpqrsuwx ]
+.RB [ -n
+.IR file ]
+.RB [ -o
+.IR file ]
+.RI [ file ...]
+.SH DESCRIPTION
+.B stest
+takes a list of files and filters by the files' properties, analogous to
+.IR test (1).
+Files which pass all tests are printed to stdout. If no files are given, stest
+reads files from stdin.
+.SH OPTIONS
+.TP
+.B \-a
+Test hidden files.
+.TP
+.B \-b
+Test that files are block specials.
+.TP
+.B \-c
+Test that files are character specials.
+.TP
+.B \-d
+Test that files are directories.
+.TP
+.B \-e
+Test that files exist.
+.TP
+.B \-f
+Test that files are regular files.
+.TP
+.B \-g
+Test that files have their set-group-ID flag set.
+.TP
+.B \-h
+Test that files are symbolic links.
+.TP
+.B \-l
+Test the contents of a directory given as an argument.
+.TP
+.BI \-n " file"
+Test that files are newer than
+.IR file .
+.TP
+.BI \-o " file"
+Test that files are older than
+.IR file .
+.TP
+.B \-p
+Test that files are named pipes.
+.TP
+.B \-q
+No files are printed, only the exit status is returned.
+.TP
+.B \-r
+Test that files are readable.
+.TP
+.B \-s
+Test that files are not empty.
+.TP
+.B \-u
+Test that files have their set-user-ID flag set.
+.TP
+.B \-v
+Invert the sense of tests, only failing files pass.
+.TP
+.B \-w
+Test that files are writable.
+.TP
+.B \-x
+Test that files are executable.
+.SH EXIT STATUS
+.TP
+.B 0
+At least one file passed all tests.
+.TP
+.B 1
+No files passed all tests.
+.TP
+.B 2
+An error occurred.
+.SH SEE ALSO
+.IR dmenu (1),
+.IR test (1)

+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.

+.TH DWM 1 dwm\-VERSION
+.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

+.TP
+.B Mod1\-Button2
+Toggles focused window between floating and tiled state.
+.TP
+.B Mod1\-Button3
+Resize focused window while dragging. Tiled windows will be toggled to the floating state.
+.SH CUSTOMIZATION
+dwm is customized by creating a custom config.h and (re)compiling the source
+code. This keeps it fast, secure and simple.
+.SH SEE ALSO
+.BR dmenu (1),
+.BR st (1)
+.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 .
+.SH BUGS
+Send all bug reports with a patch to hackers@suckless.org.

+ *
+ * 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().

+From: mrmine <mrmine1@proton.me>
+Date: Sun, 11 Dec 2022 23:31:46 +0100
+Subject: [PATCH] This Patch adds the ability to move floating windows on the x
+ and y axis with the keyboard, instead of only the mouse. This is achieved by
+ adding the two functions "movekeyboard-x" and "movekeyboard-y".

+# dwmblocks
+Modular status bar for dwm written in c.
+# usage
+To use dwmblocks first run 'make' and then install it with 'sudo make install'.
+After that you can put dwmblocks in your xinitrc or other startup script to have it start with dwm.
+# modifying blocks
+The statusbar is made from text output from commandline programs.
+Blocks are added and removed by editing the blocks.h header file.
+By default the blocks.h header file is created the first time you run make which copies the default config from blocks.def.h.
+This is so you can edit your status bar commands and they will not get overwritten in a future update.
+# patches
+Here are some patches to dwmblocks that add features that I either don't want to merge in, or that require a dwm patch to work.
+I do not maintain these but I will take pull requests to update them.

+## 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.

+Apply [1].

+
+
+## 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.

+st - simple terminal
+--------------------
+st is a simple terminal emulator for X which sucks less.
+
+
+Requirements
+------------
+In order to build st you need the Xlib header files.
+
+
+Installation
+------------
+Edit config.mk to match your local setup (st is installed into
+the /usr/local namespace by default).
+
+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
+the st terminfo entry with the following command:
+
+    tic -sx st.info
+
+See the man page for additional details.
+
+Credits
+-------
+Based on Aurélien APTEL <aurelien dot aptel at gmail dot com> bt source code.

+.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.
