## Why does st not handle utmp entries?
|
||||
|
||||
Use the excellent tool of [utmp](http://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.
|
||||
|
||||
## I get some weird glitches/visual bug on _random program_!
|
||||
|
||||
Try launching it with a different TERM: $ TERM=xterm myapp. toe(1) will give
|
||||
you a list of available terminals, but you’ll most likely switch between xterm,
|
||||
st or st-256color. The default value for TERM can be changed in config.h
|
||||
(TNAME).
|
||||
|
||||
## How do I scroll back up?
|
||||
|
||||
Using a terminal multiplexer.
|
||||
|
||||
* `st -e tmux` using C-b [
|
||||
* `st -e screen` using C-a ESC
|
||||
|
||||
## 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
|
||||
<http://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.

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.
