Display a whitespace in place of the uncovered half of the codepoint.
(I know this is incorrect and we should be considering grapheme clusters
instead of codepoints, but this is a far bigger refactoring and another
can of worms to handle with terminal emulators).
Fixes#4262
This fixes a bug in how the Lua scripts handle new comment lines.
Currently if we have a comment that is indented, when we add a new line
it inserts the `--` prefix before the automatic indentation.
```
--ABC
-- XYZ
```
After the fix, it correctly inserts the comment prefix after the
indentation:
```
--ABC
--XYZ
```
The solution I used is inspired by the ruby.kak script.
Synchronized output does not work well with various terminals
(including the linux console). It should also be unnecessary when
not going through a slow link.
This will eventually be removed if it is not proven to be useful
to some users.
TerminalUI::suspend() is responsible for undoing all Kakoune's modifications to
the terminal state, actually suspending the process, then re-applying all the
modifications after Kakoune wakes back up.
Previously, the "undo" and "reapply" steps for termios settings were both after
the suspend point, so on some platforms they were incorrect when the user
arrived back at the shell prompt.
Now, the termios "undo" step is back before the suspend point, and the undo and
reapply steps should be in exactly reversed order.
Fixes#3488.
In terminals that support it, this sequence causes the terminal to not redraw
*its* output until the application has finished, reducing redraw flickering.
The sequence is defined in:
https://gitlab.com/gnachman/iterm2/-/wikis/synchronized-updates-spec
...and is apparently also supported by kitty and libVTE.
Fixes#3482.
insert blank seems to behave differently between terminals and would
be less efficient because it still has to shift all following characters
(that we will overwrite anyway).
Fixes#3437
Diff against known state and insert/erase relevant lines.
Erase everything first to avoid insertion invalidating lines that
get out of the terminal at bottom.
This should reduce flicker, by avoiding transient states where
info/menu windows are not displayed, and paves the way for proper
diffing of the screen.
If the session wasn't valid anymore by the time the linter finishes,
writing to "$dir"/fifo would hang forever leaving temporary files in
/tmp/kak-lint.XXX and the process alive. This commit fixes that by
not writing to the fifo if the session was not valid.

Log error to debug buffer and Change the 'waiting for shell' face
to 'Error'.
Update the 'waiting for shell' message when the shell has exited
but Kakoune is still waiting on stdin/stdout/stderr to be closed.
Those fifos are accessible during %sh{...} blocks, the command fifo
executes commands written to it once the write end side is closed
(multiple open/write/close sequences are supported), the response
fifo is a simple helper fifo available to write response back to
the shell process
An example use of this feature is to request some list options
content from without being limited by the environment size:
```
%sh{
echo "echo -to-file $kak_response_fifo -quoting shell -- %opt{some_list}" > $kak_command_fifo
eval "set -- $(cat $kak_response_fifo)"
}
```
