These extensions are used by tmux and neovim, in order to make use
of 24-bit colors without facing the problems that plague the `RGB`
capability.
This should allow 24-bit colors to work "out of the box" in tmux,
without the usual workaround of adding:
set-option -ga terminal-overrides ",foot*:Tc"
...to ~/.tmux.conf.

This means that logging will be completely disabled until log_init()
has been called, which is useful to prevent log spam when running
UNITTEST{} blocks in debug builds.
Note that this doesn't change the default log level at runtime, which
was already being set to LOG_CLASS_INFO in main.c and client.c.
The new log level is also exposed to the command-line interface as
`--log-level=none`, which allows disabling logging entirely.
The configure event asks the client to change its decoration
mode. The configured state should not be applied immediately.
Clients must send an ack_configure in response to this event.
See xdg_surface.configure and xdg_surface.ack_configure for
details.
In particular, ”the configured state should *not* be applied
immediately”.
Instead, treat CSD/SSD changes like all other window dimension related
changes: store the to-be mode in win->configure, and apply it in the
surface configure event.
This fixes an issue where foot incorrectly resized the window when the
server switched between CSD/SSD at run-time.
This option controls the foreground color of the
minimize/maximize/close buttons. I.e. the color used to draw the
minimize/maximize/close glyphs.
It defaults to default background color.
Using the frame callback works most of the time, but e.g. Sway doesn’t
call it while the window is hidden, and thus prevents us from updating
the title in e.g. stacked views.
This patch uses a timer FD instead. We store a timestamp from when the
title was last updated. When the application wants to update the
title, we first check if we already have a timer running, and if so,
does nothing.
If no timer is running, check the timestamp. If enough time has
passed, update the title immediately.
If not, instantiate a timer and wait for it to trigger.
Set the minimum time between two updates to ~8ms (twice per frame, for
a 60Hz output, and ~once per frame on a 120Hz output).

This is a fairly new XTerm extension. The reply is on the format:
DCS > | text ST
XTerm replies with ‘text’ = “XTerm(366)”.
Foot replies with ‘text’ = “foot(1.6.4)”

slight refactoring to ease footclient support
Writing a sixel on top of an already existing sixel currently has the
following limitations in foot:
* The parts of the first sixel that is covered by the new sixel are
removed, completely. Even if the new sixel has transparent
areas. I.e. writing a transparent sixel on top of another
sixel *replaces* the first sixel with the new sixel, instead of
layering them on top of each other.
* The second sixel erases the first sixel cell-wise. That is, a sixel
whose size isn’t a multiple of the cell dimensions will leave
unsightly holes in the first sixel.
This patch takes care of both issues.
The first one is actually the easiest one: all we need to do is
calculate the intersection, and blend the two images. To keep things
relatively simple, we use the pixman image from the *new* image, and
use the ‘OVER_REVERSE’ operation to blend the new image over the old
one.
That is, the old image is still split into four tiles (top, left,
right, bottom), just like before. But instead of throwing away the
fifth middle tile, we blend it with the new image. As an optimization,
this is only done if the new image has transparency (P1=1).
The second problem is solved by detecting when we’re erasing an area
from the second image that is larger than the new image. In this case,
we enlarge the new image, and copy the old image into the new one.
Finally, when we enlarge the new image, there may be areas in the new
image that is *not* covered by the old image. These areas are made
transparent.
The end result is:
* Each cell is covered by at *most* 1 sixel image. I.e. the total
numbers of sixels are finite. This is important for the ‘mpv
--vo=sixel’ use case - we don’t want to end up with thousands of
sixels layered on top of each other.
* Writing an opaque sixel on top of another sixel has _almost_ zero
performance impact. Especially if the two sixels have the same size,
so that we don’t have to resize the new image. Again, important for
the ‘mpv --vo=sixel’ use case.
Closes#562
These sequences are supposed to affect the next printable ASCII
character and then reset to the previous character set, but before
this commit they were behaving like locking shifts.
This matches XTerm behavior, and fixes vttest 11.6.6.2:
Test non-VT100 ->
Test ISO-6429 colors ->
Test of VT102-style features with BCE ->
Test of screen features
Since the alt screen have no scrollback, all scrollback-* actions are
effectively no-ops when the alt screen is active.
Make them available to the client application instead.
Closes#573
When we resize the alt screen, we don’t reflow the text, we simply
truncate all the lines.
When doing this, make sure we don’t truncate in the middle of a
multi-column character.
When an auto-detected URL ended *on* the right-most column, the URL
endpoint was off by one, resulting in the underline in URL mode being
one character short.
When enabled, PUA (Private Usage Area) codepoints are always treated
as double-width glyphs, regardless of the actual glyph width.

Double-clicking on a word in the left or right margin, would line-wrap
the selection if there was a non-empty cell in the corresponding
right/left margin on the prev/next line. Regardless of whether there
was a hard linebreak or not.
Script to reprouce:
!/bin/bash
cols=$(tput cols)
printf "%*coo\nbar\n" $((${cols} - 2)) f
Run, then double click either “foo” or “bar”. Neither should select
the other part.
Closes#565
This allows you to include sub-configurations. For example, theme
files.
The ‘include’ directive is a top-level keyword. I.e. it cannot be used
inside sections.
* The included file must be specified with an absolute path
* The included file is parsed in its own scope
* Nested includes are allowed
* Multiple include directives are allowed
Closes#555
Long OSC-8 URIs, that are split up over multiple rows, are handled by
emitting one URI range on each row the URL touches.
This was done by initializing a row index variable, and then
incrementing it each loop iteration.
This caused an out-of-bounds array access when the row index reached
the maximum number of scrollback lines.
The fix is simple: make sure the row index variable wraps around,
instead of incrementing without any bounds.
Closes#552
ayl_roundtrip() has the following code:
wl_display_roundtrip(wayl->display);
while (wl_display_prepare_read(wayl->display) != 0)
wl_display_dispatch_pending(wayl->display);
wayl_flush(wayl);
If the first wl_display_roundtrip() fails, for example because the
Wayland socket has been closed, we may get stuck in the while-loop.
This happens if the read queue isn’t empty, in which case
wl_display_prepare_read() will return -1 and we’ll continue trying to
dispatch the pending events forever, never succeeding since the socket
is gone.
Closes#542
