From 8c9c920325fa10440a96736ba58ec647a0365e22 Mon Sep 17 00:00:00 2001

Subject: [PATCH] application-sync: support Synchronized-Updates
See https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec
In a nutshell: allow an application to suspend drawing until it has
completed some output - so that the terminal will not flicker/tear by
rendering partial content. If the end-of-suspension sequence doesn't
arrive, the terminal bails out after a timeout (default: 200 ms).
The feature is supported and pioneered by iTerm2. There are probably
very few other terminals or applications which support this feature
currently.
One notable application which does support it is tmux (master as of
2020-04-18) - where cursor flicker is completely avoided when a pane
has new content. E.g. run in one pane: `while :; do cat x.c; done'
while the cursor is at another pane.
The terminfo string `Sync' added to `st.info' is also a tmux extension
which tmux detects automatically when `st.info` is installed.
Notes:
- Draw-suspension begins on BSU sequence (Begin-Synchronized-Update),
and ends on ESU sequence (End-Synchronized-Update).
- BSU, ESU are "\033P=1s\033\\", "\033P=2s\033\\" respectively (DCS).
- SU doesn't support nesting - BSU begins or extends, ESU always ends.
- ESU without BSU is ignored.
- BSU after BSU extends (resets the timeout), so an application could
send BSU in a loop and keep drawing suspended - exactly like it can
not-draw anything in a loop. But as soon as it exits/aborted then
drawing is resumed according to the timeout even without ESU.
- This implementation focuses on ESU and doesn't really care about BSU
in the sense that it tries hard to draw exactly once ESU arrives (if
it's not too soon after the last draw - according to minlatency),
and doesn't try to draw the content just up-to BSU. These two sides
complement eachother - not-drawing on BSU increases the chance that
ESU is not too soon after the last draw. This approach was chosen
because the application's main focus is that ESU indicates to the
terminal that the content is now ready - and that's when we try to
draw.

Subject: [PATCH] boxdraw_v2: custom render lines/blocks/braille for perfect
alignment
It seems impossible to ensure that blocks and line drawing glyphs
align without visible gaps for all combinations of arbitrary font,
size and width/height scale factor.
This commit adds options to render most of the lines/blocks and
braille codepoints without using the font such that they align
perfectly regardless of font, size or other configuration values.
Supported codepoints are U+2500 - U+259F except dashes/diagonals,
and U28XX.
The lines/blocks data is stored as 16-bit values at boxdraw_data.h
boxdraw/braille are independent, disabled by default at config[.def].h

Subject: [PATCH] This patch allows to add spare font besides default. Some
glyphs can be not present in default font. For this glyphs st uses
font-config and try to find them in font cache first. This patch append fonts
defined in font2 variable to the beginning of font cache. So they will be
used first for glyphs that absent in default font.

Subject: [PATCH] Apply nord-theme
*"Inspired by the beauty of the arctic, the colors reflect the cold, yet
harmonious world of ice and the colorfulness of the Aurora Borealis."* - [Nord
Theme](https://www.nordtheme.com/)
There are also many [ports](https://www.nordtheme.com/ports) for other programs
like [vim](https://www.nordtheme.com/ports/vim) and
[tmux](https://www.nordtheme.com/ports/tmux) to make the overall appearance
coherent. I would recommend to use it in combination with the arc-theme for gtk
(fits perfectly).
The default behaviour of st is to reverse the fore- and background colors of
each selected cell. If you want that the selection-colors are not reveresed but
instead have fixed fore- and background colors apply on top of this patch the
[selectioncolors](../selectioncolors/)-patch. Then set the following settings
in your config.h:
static unsigned int defaultcs = 257;
static unsigned int defaultrcs = 257;
unsigned int selectionfg = 257;
unsigned int selectionbg = 0;

Subject: [PATCH] visual bell: add circle rendering mode
This commit experiments with alternative rendering of visual bell,
and as such it's extensively/excessively configurable.
It renders an overlay of a circle with configurable colors (base,
outline), position and size. Defaults to the center of the window.
Size can be relative to window or chars width, and allows for instance
to place it at the middle/side of a top/bottom tmux status-bar with
exact char height to make it look like a flashing LED at the bar, etc.
