The openurlonclick and scrollback patches are now working together,
so links can be clicked in the scrollback buffer too. This update also
adds url underlining and other improvements to the openurlonclick patch.
The full list of changes in the openurlonclick patch:
- Adds scrollback support
- Adds modkey option
- Better url detection
- Underlines url when the mouse pointer is over a link
- Opens a browser as a background process, so it won't lock the terminal anymore
- Fixes a segmentation fault bug
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.

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.

Overtyping the first half of a wide character with the
second half of a wide character results in display garbage.
This is because the trailing dummy is not cleaned up.
i.e. ATTR_WIDE, ATTR_WDUMMY, ATTR_WDUMMY
Here is a short script for demonstrating the behavior:
#!/bin/sh
alias printf=/usr/bin/printf
printf こんにちは！; sleep 2
printf '\x1b[5D'; sleep 2
printf へ; sleep 2
printf ' '; sleep 2
echo

Tested with and without alpha patch applied. Simply setting alpha to 255
seems to fix it. I didn't set `dst` on lines 263 and 273 because those
loops are impossible to reach.
from the XmbTextListToTextProperty(3) man page:
"If insufficient memory is available for the new value string, the functions
return XNoMemory. If the current locale is not supported, the functions return
XLocaleNotSupported. In both of these error cases, the functions do not set
text_prop_return."

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 standarad streams.
