## 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 doesnt 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 theyre running in xterm i.e. they dont rely on
terminfo. What you see is the current state of the “xterm compliance”.
* Some programs dont 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.

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
+ Boxdraw
+ Ligatures
+ font2
+ updated to latest version 0.8.5
## Installation for newbs
You should have xlib header files and libharfbuzz build files installed.
```
git clone https://github.com/LukeSmithxyz/st
cd st
sudo make install
```
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). There is an example `Xdefaults` file in this respository.
### 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.
