+## 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:

+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.

-# Luke's build of st - the simple (suckless) terminal
-
-The [suckless terminal (st)](https://st.suckless.org/) with some additional features that make it literally the best terminal emulator ever:
-
-## Unique features (using dmenu)
-
-+ **follow urls** by pressing `alt-l`
-+ **copy urls** in the same way with `alt-y`
-+ **copy the output of commands** with `alt-o`
-
-## Bindings for
-
-+ **scrollback** with `alt-↑/↓` or `alt-pageup/down` or `shift` while scrolling the mouse
-+ OR **vim-bindings**: scroll up/down in history with `alt-k` and `alt-j`. Faster with `alt-u`/`alt-d`.
-+ **zoom/change font size**: same bindings as above, but holding down shift as well. `alt-home` returns to default
-+ **copy text** with `alt-c`, **paste** is `alt-v` or `shift-insert`
-
-## Pretty stuff
-
-+ Compatibility with `Xresources` and `pywal` for dynamic colors.
-+ Default [gruvbox](https://github.com/morhetz/gruvbox) colors otherwise.
-+ Transparency/alpha, which is also adjustable from your `Xresources`.
-+ Default font is system "mono" at 14pt, meaning the font will match your system font.
-
-## Other st patches
-
-+ Vertcenter
-+ Scrollback
-+ font2
-+ updated to latest version 0.8.2
-
-## Installation for newbs
-
-```
-git clone https://github.com/LukeSmithxyz/st
-cd st
-sudo make install
-```
-
-Users of Arch-based distros can also install it from the AUR as [st-luke-git](https://aur.archlinux.org/packages/st-luke-git/).
-
-Obviously, `make` is required to build. `fontconfig` is required for the default build, since it asks `fontconfig` for your system monospace font. It might be obvious, but `libX11` and `libXft` are required as well. Chances are, you have all of this installed already.
-
-On OpenBSD, be sure to edit `config.mk` first and remove `-lrt` from the `$LIBS` before compiling.
-
-Be sure to have a composite manager (`xcompmgr`, `picom`, etc.) running if you want transparency.
-
-## How to configure dynamically with Xresources
-
-For many key variables, this build of `st` will look for X settings set in either `~/.Xdefaults` or `~/.Xresources`. You must run `xrdb` on one of these files to load the settings.
-
-For example, you can define your desired fonts, transparency or colors:
-
-```
-*.font: Liberation Mono:pixelsize=12:antialias=true:autohint=true;
-*.alpha: 0.9
-*.color0: #111
-...
-```
-
-The `alpha` value (for transparency) goes from `0` (transparent) to `1` (opaque).
-
-### Colors
-
-To be clear about the color settings:
-
-- This build will use gruvbox colors by default and as a fallback.
-- If there are Xresources colors defined, those will take priority.
-- But if `wal` has run in your session, its colors will take priority.
-
-Note that when you run `wal`, it will negate the transparency of existing windows, but new windows will continue with the previously defined transparency.
-
-## Notes on Emojis and Special Characters
-
-If st crashes when viewing emojis, install [libxft-bgra](https://aur.archlinux.org/packages/libxft-bgra/) from the AUR.
-
-Note that some special characters may appear truncated if too wide. You might want to manually set your prefered emoji/special character font to a lower size in the `config.h` file to avoid this. By default, JoyPixels is used at a smaller size than the usual text.
