Create a desktop-entry for st
Enables to find st in a graphical menu and to display it with a nice
icon.

If some applications still are not displaying an icon for st try the patch
[netwmicon](../netwmicon/). Programs like tint2 and alttab rely on a hardcoded
icon which has to be stored by st in the \_NET\_WM\_ICON window-property.

211964d56e ignore C1 control characters in UTF-8 mode
Ignore processing and printing C1 control characters in UTF-8 mode.
These are in the range: 0x80 - 0x9f.

By default in st the mode is set to UTF-8.

This matches more the behaviour of xterm with the options -u8 or +u8 also.
Also see the xterm resource "allowC1Printable".

Let me know if this breaks something, in most cases I don't think so.

f17abd25b3 Add support for DSR response "OK" escape sequence
"VT100 defines an escape sequence [1] called Device Status Report (DSR). When
the DSR sequence received is `csi 5n`, an "OK" response `csi 0n` is returned.
This patch adds that "OK" response.

I encountered this missing sequence when I noticed that fzf [2] would clobber
my prompt whenever completing a find.

To test that ST doesn't currently respond to `csi 5n`, use fzf's shell
extension in ST's repo to complete the path for a file.

    my-fancy-prompt $ vim **<tab>
    <select a file>
    st.c

Select a file with <enter>, and notice that fzf clobbers some or all of your
prompt.

After applying this patch, do the same test as above and notice that fzf has no
longer clobbered your prompt by placing the file name in the correct position
in your command.

    my-fancy-prompt $ vim **<tab>
    <select a file>
    my-fancy prompt $ vim st.c

Thank you for considering my first patch submission.

8629d9a1da code-golfing: cleanup osc color related code
* adds missing function prototype
* move xgetcolor() prototype to win.h (that's where all the other x.c
  func prototype seems to be declared at)
* check for snprintf error/truncation
* reduces code duplication for osc 10/11/12
* unify osc_color_response() and osc4_color_response() into a single function

the latter two was suggested by Quentin Rameau in his patch review on
the hackers list.

ef0551932f base64_digits: reduce scope, implicit zero, +1 size
the array is not accessed outside of base64dec() so it makes sense to
limit it's scope to the related function. the static-storage duration of
the array is kept intact.

this also removes unnecessary explicit zeroing from the start and end of
the array. anything that wasn't explicitly zero-ed will now be
implicitly zero-ed instead.

the validity of the new array can be easily confirmed via running this
trivial loop:

	for (int i = 0; i < 255; ++i)
		assert(base64_digits[i] == base64_digits_old[i]);

lastly, as pointed out by Roberto, the array needs to have 256 elements
in order to able access it as any unsigned char as an index; the
previous array had 255.

however, this array will only be accessed at indexes which are
isprint() || '=' (see `base64dec_getc()`), so reducing the size of the
array to the highest printable ascii char (127 AFAIK) + 1 might also be
a valid strategy.

ea7cd7b62f Fix mousereport
This patch replaces the previous one I sent.

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.

1d3142da96 fix a problem that the standard streams are unexpectedly closed
In the current implementation, the slave PTY (assigned to the variable
`s') is always closed after duplicating it to file descriptors of
standard streams (0, 1, and 2).  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.

2ec571a30c Add 14th bit to XK_SWITCH_MOD bitmask
The bits of uint signal in an XKeyEvent which concern the key group (keyboard
layout) are bits 13 and 14, as documented here:
https://www.x.org/releases/X11R7.7/doc/libX11/XKB/xkblib.html#Groups_and_Shift_Levels
In the older version, only bit 13 was marked as part of XK_SWITCH_MOD, this
causes issues for users who have more than two keymaps. the 14th bit is not
in ignoremod, key sequences are not caught by match(), if they switch to a third
or fourth keyboard.

818ec746f4 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'

...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:

    ÿÿ

...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)

		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.

a2a704492b 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
exploited.

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'

94b8ec0021 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.

475a0a36cb Revert "support REP (repeat) escape sequence"
This reverts commit e8392b282c.

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).

e8392b282c 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.

bda9c9ffa6 Make shift+wheel behaves as shift+Prev/Next
St uses a very good hack where mouse wheel genereates ^Y and ^E,
that are the same keys that less and vi uses for backward and
fordward scrolling. 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.

8211e36d28 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 11625c7166
	Author: czarkoff@gmail.com <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.

1d59091065 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).

019449a7e6 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.

21e0d6e8b8 Add support for scroll(1)
Scroll is a program that stores all the lines of its child and be used in st as
a way of implementing scrollback.

This solution is much better than implementing the scrollback in st itself
because having a different program allows to use it in any other program
without doing modifications to those programs.

28ad288399 mouseshortcuts: fix custom modifier on release
This line didn't work at mshortcuts at config.h:

  /*  mask       button   function  arg       release */
    { ShiftMask, Button2, selpaste, {.i = 0}, 1 },

and now it does work.

The issue was that XButtonEvent.state is "the logical state ... just prior
to the event", which means that on release the state has the Button2Mask
bit set because button2 was down just before it was released.

The issue didn't manifest with the default shift + middle-click on release
(to override mouse mode) because its specified modifier is XK_ANY_MOD, at
which case match(...) ignores any specific bits and simply returns true.

The issue also doesn't manifest on press, because prior to the event
Button<N> was not down and its mask bit is not set.

Fix by filtering out the mask of the button which we're currently matching.

We could have said "well, that's how button events behave, you should
use ShiftMask|Button2Mask for release", but this both not obvious to
figure out, and specifically here always filtering does not prevent
configuring any useful modifiers combination. So it's a win-win.

2e54a21b5a OSC 52 - copy to clipboard: don't limit to 382 bytes
Strings which an application sends to the terminal in OSC, DCS, etc
are typically small (title, colors, etc) but one exception is OSC 52
which copies text to the clipboard, and is used for instance by tmux.

Previously st cropped these strings at 512 bytes, which for OSC 52
limited the copied text to 382 bytes (remaining buffer space before
base64). This made it less useful than it can be.

Now it's a dynamic growing buffer. It remains allocated after use,
resets to 512 when a new string starts, or leaked on exit.

Resetting/deallocating the buffer right after use (at strhandle) is
possible with some more code, however, it doesn't always end up used,
and to cover those cases too will require even more code, so resetting
only on new string is good enough for now.

7ceb3d1f72 STREscape: don't trim prematurely
STRescape holds strings in escape sequences such as OSC and DCS, and
its buffer is 512 bytes.

If the input is too big then trailing chars are ignored, but the test
was off-by-1 such that it took 510 chars instead of 511 (before a
terminating NULL is added).

Now the full size can be utilized.

ea4d933ed9 base64dec: don't read out of bounds
Previously, base64dec checked terminating input '\0' every 4 calls to
base64dec_getc, where the latter progressed one or more chars on each
call, and could read past '\0' in the way it was used.

The input to base64dec currently comes only from OSC 52 escape seq
(copy to clipboard), and reading past '\0' or even past the buffer
boundary was easy to trigger.

Also, even if we could trust external input to be valid base64, there
are different base64 standards, and not all of them require padding
to 4 bytes blocks (using trailing '=' chars).

It didn't affect short OSC 52 strings because the buffer is initialized
to 0's, so typically it did stop within the buffer, but if the string
was trimmed to fit (the buffer is 512 bytes) then it did also read past
the end of the buffer, and the decoded suffix ended up arbitrary.

This patch makes base64dec_getc not progress past '\0', and instead
produce fake trailing padding of '='.

Additionally, at base64dec, if padding is detected at the first or
second byte of a quartet, then we identify it as invalid and abort
(a valid quartet has at least two leading non-padding bytes).

a2c479c4c8 mouse shortcuts: allow using forcemousemod (e.g. shift)
The recent mouse shurtcuts commits allow customization, but ignore
forcemousemod mask (default: shift) as a modifier, for no good reason
other than following the behavior of the KB shortcuts.

Allow using forcemousemod too, which now can be used to invoke
different shortcuts, though the automatic effect of forcemousemod will
be lost for buttons which use mask with forcemousemod.

E.g. the default is:

static uint forcemousemod = ShiftMask;
...
{ XK_ANY_MOD,           Button4, ttysend,        {.s = "\031"} },
...

where ttysend will be invoked for button4 with any mod when not in mouse
mode, and with shift when in mouse mode.

Now it's possible to do this:
{ ShiftMask,            Button4, ttysend,        {.s = "foo"} },
{ XK_ANY_MOD,           Button4, ttysend,        {.s = "\031"} },

Which will invoke ttysend("foo") while shift is held and ttysend("\031")
otherwise. Shift still overrides mouse mode, but will now send "foo".

Previously with this setup the second binding was always invoked
because the forceousemod mask was always removed from the event.

Buttons which don't use forcemousemod behave the same as before.

This is useful e.g. for the scrollback mouse patch, which wants to
configure shift+wheel for scrollback, while keeping the normal behavior
without shift.

b6d280de6d mouse shortcuts: allow override for all shortcuts
Allow forceselmod to override all mouse shortcuts rather than only
selection, and rename it to forcemousemod as it's now more appropriate.

This will affect mouse shortcuts which use mask other than XK_ANY_MOD.

This does not affect the default behavior because the default mouse
shortcuts (wheel) use XK_ANY_MOD, where forceselmod already activated
the override also before this change.

Previously, if a mouse shortcut was configured with a specific mod and
forceselmod was held, then the shortcut did not execute unless the
configured mod included forceselmod.

a8cb8e9454 fix use after free in font caching algorithm
Current font caching algorithm contains a use after free error. A font
removed from `frc` might be still listed in `wx.specbuf`. It will lead
to a crash inside `XftDrawGlyphFontSpec()`.

Steps to reproduce:
$ st -f 'Misc Tamsyn:scalable=false'
$ curl https://www.cl.cam.ac.uk/~mgk25/ucs/examples/UTF-8-demo.txt

Of course, result depends on fonts installed on a system and fontconfig.
In my case, I'm getting consistent segfaults with different fonts.

I replaced a fixed array with a simple unbounded buffer with a constant
growth rate. Cache starts with a capacity of 0, gets increments by 16,
and never shrinks. On my machine after `cat UTF-8-demo.txt` buffer
reaches a capacity of 192. During casual use capacity stays at 0.

useful for example to specify preprocessor macros with -D.

CFLAGS could be used instead, but CPPFLAGS is more correct and is expected

Debian packages make use of CPPFLAGS, but the variable is currently
being ignored unless manually appended to CFLAGS.

a3beb626d2 Remove x.c dependency on term
The xinit function only needs to the rows/cols, so pass those in rather
than accessing term directly.  With a bit of arithmetic, we are able to
avoid the need for term.row and term.col in x2col, y2row, and
xdrawglyphfontspecs as well, completing the removal.

Term is now fully internal to st.c.

05c66cb37d Split mode bits between Term and TermWindow
Moves the mode bits used by x.c from Term to TermWindow, absorbing
UI/input-related mode bits (visible/focused/numlock) along the way.

This is gradually reducing external references to Term.  Since
TermWindow is already internal to x.c, we add xsetmode() to allow st to
modify window bits in accordance with escape sequences.

IS_SET() is redefined accordingly (term.mode in st.c, win.mode in x.c).

e829e13bb1 Apply ATTR_REVERSE after ATTR_FAINT
An example where the new behaviour makes more sense:

Suppose some text is formatted with ATTR_FAINT for red for the foreground, so it
is rendered in a dark red. In that case, when selected with the mouse, the
intended behaviour is that foreground and background color are swapped: so the
selection should be rendered in dark red and the text in the default background
color.

Before this patch, what happened was that the selection would be in normal red
and the text in the darkened background color, making it almost unreadable.

For an example application that uses the FAINT attribute, try dmesg from
util-linux with color support, it uses FAINT for segfault messages.

f2bfd513b1 keep some glyph modes for the cursor
st currently does not keep any mode for the cursor that was active
in the underlying glyph (e.g. italic text), the mode is always
ATTR_NULL [1].  At [2] you can find a screenshot that shows the
implications.  Other terminals (at least vte-based, such as
XFCE-terminal) keep some modes for the cursor.  I find the current
behaviour very disruptive, so here is a patch that keeps a few
(arbitrarily chosen) modes for the cursor.

fa9a459972 Fixed 'missing glyph doesn't use fontconfig config substitutions' bug
XftFontMatch does display-specific font configuration (commit 528241a).
Nice. Unfortunately, when we switched from FcFontMatch, we also stopped
storing the post-Fc{Config,Default}Substitute FcPattern for future
lookups. The result is that if a glyph isn't found in the primary font,
secondary font lookups use the original FcPattern, not the configured
one. If you have custom fontconfig rules (like me), this can be
disappointing.

I basically just copied the guts out of XftFontMatch[1] and saved
the intermediate configured FcPattern. Could be related to the bug that
inspired commit 4242027.

When using st with screen, I've bound next, prev, new screen to

when this combination of modifiers is pressed, st does not seem to

Alt-Down etc., but combinations are not). While I'm not terribly
familiar with this, I have tried to hack config.h in a more or less

424202798b Initial font size issue.
Hi,

When I specify a font by point size (I'm using "Inconsolata:size=12"),
characters that are substituted from another font because they are not in the
main one appear too small.  Doing a zoom reset fixes it.  For example:

Before: http://i.imgur.com/G4Mfv4X.png
After:  http://i.imgur.com/PMDhfQA.png

I found that adding the pixel size (acquired from the initial font load) to the
pattern then reloading the font fixes the problem.  I'm not sure if this is a
proper fix, though.

235b438e68 Consistent Alt+BackSpace behavior
The default config specifies BackSpace as "\177". The default behavior
should persist across modifier keys, commonly Mod1 (Alt or Meta) which
is widely used to delete a word on readline and text editors, notably
Emacs.

This will make Alt+BackSpace behaves as expected, i.e. sends "\033\177"
instead of "\033\010" as previous default behavior.

528241aa38 Use XftFontMatch in place of FcFontMatch.
git am -s didn't like your patch:

From: Mark Edgar <medgar123@gmail.com>

XftFontMatch calls XftDefaultSubstitute which configures various match
properties according to the user's configured Xft defaults (xrdb) as well as
according to the current display and screen. Most importantly, the screen DPI
is computed [1]. Without this, st uses a "default" DPI of 75 [2].

60aeb37edb delete clipboard properties after pasting them
https://tronche.com/gui/x/icccm/sec-2.html#s-2.4 specifies:
> Once all the data in the selection has been retrieved,
> the requestor should delete the property in the SelectionNotify request

Most Clipboard-Owners ignore whether or not the property is already set,
so this is mostly a cosmetic change to keep the windows property list clean.

However, at least synergy decides to wait for the requestor to delete
the properties if they are already set by a previous paste (from synergy).

39964614b7 st: Fix off-by-one error when calculating character width.
LEN(str) is one larger than strlen(str) because it also counts the zero
terminator. The original code would include the .notdef glyph (since it'll
try to encode character 0, which gets encoded to the .notdef glyph) when
measuring the average dimensions of printable ascii characters.

This causes problems with fonts like GNU Unifont where the .notdef glyph is
not the same width as the usual half-width characters.

Before this patch, when pasting over BUFSIZE (8192 bytes here), st would
do the following:

    \e[200~...8192 bytes...\e[201~\e[200~...remaining bytes...\e[201~

With this patch, the start marker is only sent when the offset is 0 (at
the beginning of selnotify) and the end marker is only sent when the
remaining bytes to read are 0 (at the end).

For short pastes, both conditions are true in the same iteration.

For long pastes, it removes the extra markers in the middle, keeping the
intended wrapping:

    \e[200~...8192 bytes......remaining bytes...\e[201~

`drawregion' is always called with `x1' and `y1' values of 0, but if

ae1923d275 Clean up xdraws and optimize glyph drawing with non-unit kerning values
I have another patch here for review that optimizes the performance of
glyph drawing, primarily when using non-unit kerning values, and fixes a
few other minor issues. It's dependent on the earlier patch from me that
stores unicode codepoints in a Rune type, typedef'd to uint_least32_t.

This patch is a pretty big change to xdraws so your scrutiny is
appreciated.

First, some performance numbers. I used Yu-Jie Lin termfps.sh shell
script to benchmark before and after, and you can find it in the
attachments. On my Kaveri A10 7850k machine, I get the following
results:

Before Patch
============

1) Font: "Liberation Mono:pixelsize=12:antialias=false:autohint=false"
   cwscale: 1.0, chscale: 1.0
   For 273x83 100 frames.
   Elapsed time :     1.553
   Frames/second:    64.352
   Chars /second: 1,458,159

2) Font: "Inconsolata:pixelsize=14:antialias=true:autohint=true"
   cwscale: 1.001, chscale: 1.001
   For 239x73 100 frames.
   Elapsed time :   159.286
   Frames/second:     0.627
   Chars /second:    10,953

After Patch
===========

3) Font: "Liberation Mono:pixelsize=12:antialias=false:autohint=false"
   cwscale: 1.0, chscale: 1.0
   For 273x83 100 frames.
   Elapsed time :     1.544
   Frames/second:    64.728
   Chars /second: 1,466,690

4) Font: "Inconsolata:pixelsize=14:antialias=true:autohint=true"
   cwscale: 1.001, chscale: 1.001
   For 239x73 100 frames.
   Elapsed time :     1.955
   Frames/second:    51.146
   Chars /second:   892,361

As you can see, while the improvements for fonts with unit-kerning is
marginal, there's a huge ~81x performance increase with the patch when
using kerning values other than 1.0.

So what does the patch do?

The `xdraws' function would render each glyph one at a time if non-unit
kerning values were configured, and this was the primary cause of the
slow down. Xft provides a handful of functions which allow you to render
multiple characters or glyphs at time, each with a unique <x,y> position,
so it was simply a matter of massaging the data into a format that would
allow us to use one of these functions.

I've split `xdraws' up into two functions. In the first pass with
`xmakeglyphfontspecs' it will iterate over all of the glyphs in a given
row and it will build up an array of corresponding XftGlyphFontSpec
records. Much of the old logic for resolving fonts for glyphs using Xft
and fontconfig went into this function.

The second pass is done with `xrenderglyphfontspecs' which contains the
old logic for determining colors, clearing the background, and finally
rendering the array of XftGlyphFontSpec records.

There's a couple of other things that have been improved by this patch.
For instance, the UTF-32 codepoints in the Line's were being re-encoded
back into UTF-8 strings to be passed to `xdraws' which in turn would then
decode back to UTF-32 to verify that the Font contained a matching glyph
for the code point. Next, the UTF-8 string was being passed to
`XftDrawStringUtf8' which internally mallocs a scratch buffer and decodes
back to UTF-32 and does the lookup of the glyphs all over again.

This patch gets rid of all of this redundant round-trip encoding and
decoding of characters to be rendered and only looks up the glyph index
once (per font) during the font resolution phase. So this is probably
what's responsible for the marginal improvements seen when kerning values
are kept to 1.0.

I imagine there are other performance improvements here too, not seen in
the above benchmarks, if the user has lots of non-ASCII code plane characters
on the screen, or several different fonts are being utilized during
screen redraw.

Anyway, if you see any problems, please let me know and I can fix them.

c990abfedf Fix empty selection highlighting bug.
When user clicks LMB, one character is selected, but will not be copied
to selection until the user moves cursor a bit. Therefore, the character
should not be highlighted as selected yet.

Before the patch, the trick was not to mark line as dirty to avoid
highlighting it. However, if user has already selected something and
clicks in line that contains selection, selclear sets the line as dirty
and one character is highlighted when it should not.

This patch replaces dirty trick with explicit check for sel.mode inside
selected().

it just gets ignored and I have not been able to find anywhere in x.org's

However, if you use XkbBell() then you can have a process listening for
the XkbBellNotifyEvent that is produced and either alert you visually or
play an audio file or whatever you want as your notification. You have
to include one more header file but the function seems to be compiled as

SI (0x0F or ^O) means Shift In, and it selects G1 charset definition,
and SO (0x0E or ^N) means Shift Out, and it selects G0 charset
definition, but st was doing just the inverse.

## 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 manualy run `tic -s st.info`.

* Some programs dont 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 youll 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?

## I would like to have utmp and/or scroll functionality by default

have to modify the value of utmp and scroll variables.

## 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 of librt, despite it begin 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.
## Backspace key does not work

## 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.
As of 2022-09-05 this now seems to be finally fixed in libXft 2.3.5:
https://gitlab.freedesktop.org/xorg/lib/libxft/-/blob/libXft-2.3.5/NEWS

.B \-i
will fixate the position given with the -g option.
.TP
.BI \-o " file"
.BI \-n " name"
defines the window instance name (default $TERM).
.TP
.BI \-o " iofile"
writes all the I/O to
.I file.
.I iofile.
This feature is useful when recording st sessions. A value of "-" means
standard output.
.TP
.BI \-T " title"
defines the window title (default 'st').

.BI \-t " title"
defines the window title (default 'st').
.TP
@ -58,15 +91,74 @@ defines the window title (default 'st').
embeds st within the window identified by
.I windowid
.TP
.BI \-l " line"
use a tty
.I line
instead of a pseudo terminal.
.I line
should be a (pseudo-)serial device (e.g. /dev/ttyS0 on Linux for serial port
0).
When this flag is given
remaining arguments are used as flags for
.BR stty(1).
By default st initializes the serial line to 8 bits, no parity, 1 stop bit
and a 38400 baud rate. The speed is set by appending it as last argument
(e.g. 'st -l /dev/ttyS0 115200'). Arguments before the last one are
.BR stty(1)
flags. If you want to set odd parity on 115200 baud use for example 'st -l
/dev/ttyS0 parenb parodd 115200'. Set the number of bits by using for
example 'st -l /dev/ttyS0 cs7 115200'. See
.BR stty(1)
for more arguments and cases.
.TP
.B \-v
prints version information to stderr, then exits.
.TP
.BI \-e " program " [ " arguments " "... ]"
.BI \-e " command " [ " arguments " "... ]"
st executes
.I program
.I command
instead of the shell. If this is used it
.B must be the last option
on the command line, as in xterm / rxvt.
This option is only intended for compatibility,
and all the remaining arguments are used as a command
even without it.
