The changes include handling these sequences in the `strhandle` function of `st.c`, allowing applications to reset colors to their default values. The OSC sequences originated from Xterm control sequences and are now widely used in terminal applications and supported by many terminal emulators. For applications, this allows them to reset colors to default values without needing to know the colors beforehand. Signed-off-by: Ayman Bagabas

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.

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 b950ce8), 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.

Partially add back in "support REP (repeat) escape sequence"

Some notes: It was reverted because it caused some issues with ncurses in some configurations, namely when using BSD padding (--enable-bsdpad, BSD_TPUTS) in ncurses it caused issues with repeating digits. A fix has been upstreamed in ncurses since snapshot 20200523. The fix is also backported to OpenBSD -current.

There is currently a bug in older ncurses versions (like on OpenBSD) where a fix for a bug with REP is not backported yet. Most likely in tty/tty_update.c: Noticed while using lynx (which uses ncurses/curses). To reproduce using lynx: echo "Z0000000" | lynx -stdin or using the program: int main(void) { WINDOW *win; win = initscr(); printw("Z0000000"); refresh(); sleep(5); return 0; } This prints "ZZZZZZZ" (incorrectly).

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

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 c3dc66b86a027b703045e3a3ec884520c540cdfe 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 b7d856c8b649252113f44cb5c049768af57511c1 parent f15b5254a0db34dab7bdc0cb1866a9fe66cc87fe 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).
