This patch adds the ability to configure st via Xresources.

Apply scrollback patch

Scroll back through terminal output using Shift+{PageUp, PageDown}.
Apply anysize patch

By default, st's window size always snaps to the nearest multiple of the
character size plus a fixed inner border (set with borderpx in
config.h). When the size of st does not perfectly match the space
allocated to it (when using a tiling WM, for example), unsightly gaps
will appear between st and other apps, or between instances of st.

This patch allows st to resize to any pixel size, makes the inner border
size dynamic, and centers the content of the terminal so that the
left/right and top/bottom borders are balanced. With this patch, st on a
tiling WM will always fill the entire space allocated to it.
Apply externalpipe patch

Reading and writing st's screen through a pipe.

fix unicode glitch in DCS strings, patch by Tim Allen

Reported on the mailinglist:

I discovered recently that if an application running inside st tries to
send a DCS string, subsequent Unicode characters get messed up. For
example, consider the following test-case:

    printf '\303\277\033P\033\\\303\277'


  - \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:


...which is to say, the empty DCS string is ignored. However, if I run
that command inside st (as of commit 9ba7ecf), I get:


...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
  - 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

I've tried the above patch and it fixes my problem, but I don't know if
it introduces any others.

config.def.h: add an option allowwindowops, by default off (secure)

Similar to the xterm AllowWindowOps option, this is an option to allow or
disallow certain (non-interactive) operations that can be insecure or

NOTE: xsettitle() is not guarded by this because st does not support printing
the window title. Else this could be exploitable (arbitrary code execution).
Similar problems have been found in the past in other terminal emulators.

The sequence for base64-encoded clipboard copy is now guarded because it allows
a sequence written to the terminal to manipulate the clipboard of the running
user non-interactively, for example:

printf '\x1b]52;0;ZWNobyBoaQ0=\a'

tiny style fix
94b8ec00 — Hiltjo Posthuma 3 years ago
Partially add back in "support REP (repeat) escape sequence"

Add the functionality back in for xterm compatibility, but do not expose the
capability in st.info (yet).

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.

Call xsetcursor to set win.cursor in main

In xsetcursor, remove "DEFAULT(cursor, 1)" because 0 is a valid value.
Increase max allowed value of cursor from 6 to 7 (st extension).
