Unfortunately, st interprets CSI ? u as DECRC (restore cursor position). reproduce with 'printf "\x1b[?u"; cat'. fish could work around this by switching to the alternate screen before running this query; but that might cause tearing on terminals that don't support Synchronized Output. I'm not sure. In the meantime, let's correct our parser. This adds a redundant else-after-return, for consistency with the surrounding code.

For example: printf "\033]0;\007" Some applications, like termdown, expect this functionality. xterm implements it, but it seems that most other terminal emulators don't. In any case, I don't see why there should ever be a case where the st window doesn't have a title property.

Without checking for a private marker, st will perform a scroll up operation when XTSMGRAPHICS is seen, which can cause unexpected display artifacts.

The reason is that selscroll() calls selnormalize() and that cannot find the original range anymore. It's all empty lines now, so it snaps to "select the whole line".

base64_digits: reduce scope, implicit zero, +1 size

The following changes are made in this patch: - Fix tracking of pressed buttons. Previously, pressing two buttons and then releasing one would make st think no buttons are pressed, which in particular broke MODE_MOUSEMOTION. - Always send the lowest-numbered pressed button on motion events; when no button is pressed for a motion event in MODE_MOUSEMANY, then send a release. This matches the behaviour of xterm. (Previously, st sent the most recently pressed button in the motion report.) - Remove UB (?) access to potentially inactive struct member e->xbutton.button of XEvent union. - Fix (unlikely) possibility of overflow for large button numbers. The one discrepancy I found between st and xterm is that xterm sometimes encodes buttons with large numbers (>5) strangely. E.g., xterm reports presses of buttons 8 and 9 as releases, whereas st properly (?) encodes them as presses.

fix a problem that the standard streams are unexpectedly closed

However, when the allocated slave PTY `s' is already one of 0, 1, or 2, this causes unexpected closing of a standard stream. The same problem occurs when the file descriptor of the master PTY (the variable `m') is one of 0, 1, or 2. In this patch, the original master PTY (m) is closed before it would be overwritten by duplicated slave PTYs. The original slave PTY (s) is closed only when it is not one of the stanrad streams.

For example, consider the following test-case: printf '\303\277\033P\033\\\303\277' ...where: - \303\277 is the UTF-8 encoding of U+00FF LATIN SMALL LETTER Y WITH DIAERESIS (ÿ). - \033P is ESC P, the token that begins a DCS string. - \033\\ is ESC \, a token that ends a DCS string. - \303\277 is the same ÿ character again. If I run the above command in a VTE-based terminal, or xterm, or QTerminal, or pterm (PuTTY), I get the output: ÿÿ ...which is to say, the empty DCS string is ignored. However, if I run that command inside st (as of commit 9ba7ecf), I get: ÿÃ¿ ...where those last two characters are \303\277 interpreted as ISO8859-1 characters, instead of UTF-8. I spent some time tracing through the state machines in st.c, and so far as I can tell, this is how it works currently: - ESC P sets the "ESC_DCS" and "ESC_STR" flags, indicating that incoming bytes should be collected into the strescseq buffer, rather than being interpreted. - ESC \ sets the "ESC_STR_END" flag (when ESC is received), and then calls strhandle() (when \ is received) to interpret the collected bytes. - If the collected bytes begin with 'P' (i.e. if this was a DCS string) strhandle() sets the "ESC_DCS" flag again, confusing the state machine. If my understanding is correct, fixing the problem should be as easy as removing the line that sets ESC_DCS from strhandle(): diff --git a/st.c b/st.c index ef8abd5..b5b805a 100644 --- a/st.c +++ b/st.c @@ -1897,7 +1897,6 @@ strhandle(void) xsettitle(strescseq.args[0]); return; case 'P': /* DCS -- Device Control String */ - term.mode |= ESC_DCS; case '_': /* APC -- Application Program Command */ case '^': /* PM -- Privacy Message */ return; I've tried the above patch and it fixes my problem, but I don't know if it introduces any others.

Similar problems have been found in the past in other terminal emulators.

commit e8392b282c2eaa28725241a9612804fb55113da4 parent f8afebdfa0cc9a57b22c39c47e9b585f69453eb7 Author: Avi Halachmi (:avih) Date: Thu, 14 May 2020 18:18:07 +0300 support REP (repeat) escape sequence The sequence \e[Nb prints the last printed char N (more) times if it's printable, and it's ignored after newline or other control chars. This is Ecma-048/ANSI-X3.6 sequence and not DEC VT. It's supported by xterm, and ncurses uses it when possible, e.g. when TERM is xterm* (and with this commit also st*). xterm supports only codepoints<=255, possibly due to internal limits. We support any value/codepoint which was placed in a cell. To test: - tput rep 65 4 -> prints 'AAAA' - printf "\342\225\246\033[4b" -> prints U+2566 1+4 times.

Make shift+wheel behaves as shift+Prev/Next

Scroll, as many terminal emulators, use shift+Prev/Next for scrolling, but it is also using ^E and ^Y for scroling, characters that are reserved in the POSIX shell in emacs mode for end of line and yanking, making scroll unsable in st. This patch adds a new hack, making shift+wheel returning the same sequences than shift+Prev/Next, meaning that scroll or any other similar program will not be able to differentiate between them.

fix for incorrect (partial) written sequences when libc wcwidth() == -1

commit 8211e36d281990a39db1853bcd454ac59e53d521 parent 87545c612e8ab6e7cd1ef38e2355d0cb86df79f2 Author: Hiltjo Posthuma Date: Sat, 9 May 2020 13:56:28 +0200 fix for incorrect (partial) written sequences when libc wcwidth() == -1 Fix an issue with incorrect (partial) written sequences when libc wcwidth() == -1. The sequence is updated to on wcwidth(u) == -1: c = "\357\277\275" but len isn't. A way to reproduce in practise: * st -o dump.txt * In the terminal: printf '\xcd\xb8' - This is codepoint 888, on OpenBSD it reports wcwidth() == -1. - Quit the terminal. - Look in dump.txt (partial written sequence of "UTF_INVALID"). This was introduced in: " commit 11625c7166b7e4dad414606227acec2de1c36464 Author: czarkoff@gmail.com Date: Tue Oct 28 12:55:28 2014 +0100 Replace character with U+FFFD if wcwidth() is -1 Helpful when new Unicode codepoints are not recognized by libc." Change: Remove setting the sequence. If this happens to break something, another solution could be setting len = 3 for the sequence.

auto-sync: draw on idle to avoid flicker/tearing

2019-02-26T20:37:49Z
commit 1d590910652519268152eae6b97cf30ace4e90c0 parent d6ea0a1a61853dd892029a7126e7fdb70c371878 Author: Avi Halachmi (:avih) Date: Tue, 26 Feb 2019 22:37:49 +0200 auto-sync: draw on idle to avoid flicker/tearing st could easily tear/flicker with animation or other unattended output. This commit eliminates most of the tear/flicker. Before this commit, the display timing had two "modes": - Interactively, st was waiting fixed `1000/xfps` ms after forwarding the kb/mouse event to the application and before drawing. - Unattended, and specifically with animations, the draw frequency was throttled to `actionfps`. Animation at a higher rate would throttle and likely tear, and at lower rates it was tearing big frames (specifically, when one `read` didn't get a full "frame"). The interactive behavior was decent, but it was impossible to get good unattended-draw behavior even with carefully chosen configuration. This commit changes the behavior such that it draws on idle instead of using fixed latency/frequency. This means that it tries to draw only when it's very likely that the application has completed its output (or after some duration without idle), so it mostly succeeds to avoid tear, flicker, and partial drawing. The config values minlatency/maxlatency replace xfps/actionfps and define the range which the algorithm is allowed to wait from the initial draw-trigger until the actual draw. The range enables the flexibility to choose when to draw - when least likely to flicker. It also unifies the interactive and unattended behavior and config values, which makes the code simpler as well - without sacrificing latency during interactive use, because typically interactively idle arrives very quickly, so the wait is typically minlatency. While it only slighly improves interactive behavior, for animations and other unattended-drawing it improves greatly, as it effectively adapts to any [animation] output rate without tearing, throttling, redundant drawing, or unnecessary delays (sounds impossible, but it works).

Vargas Caballero Date: Fri, 10 Apr 2020 22:50:23 +0200 Add terminfo entries for backspace mode St used to use backspace as BS until the commit 230d0c8, but due to general lack of knowledge of lusers, we moved to the most common configuration in linux to avoid answering the same question 3 times per month. With the most common configuration we have a backspace that returns a DEL, and we have a Delete key that doesn't return a DEL character neither a BS. When dealing with devices connected using a serial line (or even with Plan9) it is more common Backspace as BS and Delete as DEL. For this reason, st is not always the best tool when you talk with a serial device. This patch adds new terminfo entries for Backspace as BS and Delete as DEL. A patch for confg.h is also added, to make easier switch between both configurations.
