If I type
:echo -mx
I get no completions, even when I move the cursor on the x.
If I replace the x with a k, I get a completion "-markup".
The odd thing is that if I accept the completion while the cursor is
on the k, then the commandline will be
:echo markupk
Evidently, the characters under cursor (x/k) influence the completion
(actually all letters right of the cursor do), but they are not
incorporated in the final result, which is weird.
I think there are two consistent behaviors:
1. Compute completions only from characters left of the cursor. We already
do this in insert mode completion, and when completing the command name
in a prompt.
2. Compute completions from the whole token, and when accepting a completion,
replace the whole token.
Most readline-style completion systems out there implement 1. A
notable exception is fish's tab-completion. I think we should stick
to 1 because it's more predictable and familiar. Do that.
This allows us to get rid of a special case for completing command
names, because the new behavior subsumes it.
In fact, I think this would allow us to get rid of most "pos_in_token"
or "cursor_pos" completer parameters. I believe the only place where we
it's actually different from the end of the query is in "shell-script"
completers, where we expose "$kak_pos_in_token". I think we can still
remove that parameter and just cut the commandline at the cursor
position before passing it to a "shell-script" completer. Then we
also don't need "$kak_token_to_complete" (but we can still keep
expose them for backwards compatibility).
Just like in the parent commit, this requires us to use a non-owning
type. Technically, these strings all benefit from SSO, so there is
no lifetime issue, but we can't deduce that from the types.
I guess we could use InplaceString just as well.
complete() merely iterates over its input, so we can pass it a range
instead of a vector. For some reason, this requires specifying the
type of the static array, or else its elements become String which
triggers this assertion:
static_assert(not std::is_same<decltype(*begin(container)), String>::value,
"complete require long lived strings, not temporaries");
Specify the type with an explicit Array<StringView, 8>. This is
pretty ugly but the alternative of appending "_sv" to every single
array element seems worse?
If we modify the vector of user modes while complete() is iterating
over, we could crash -- but that scenario is impossible since both
only happen inside the single-threaded server process.

Instead of triming only buffer ranges, add a trim_from method to
display line to keep the initial N columns, we know how many columns
are used by non-trimable widgets in DisplaySetup::widget_columns so
we can just pass this.
Also restore the previous logic for face merging
Fixes#4670
Make the column highlighter faces final, and change final logic to
give precedence to the base face when both the base and new face are
final.
Fixes#4669
Terminals that support CSI u escape codes (like iTerm2, Kitty and foot)
allow us to map <s-backspace> independently of <backspace>.
Users expect that <s-backspace> does the same as <backspace>,
especially when typing ALL_CAPS. Make it so.
The first version of 0cf719103 (Make Shift+Space insert a space in
insert mode, 2022-02-09) did that already but I later dropped it
because I wasn't sure if it's right.
Always start with full buffer lines and trim the display buffer at
the very end, treat non-range display atoms as non-trimable in that
case and keep track of how many columns are occupied by "widgets"
such as line numbers or flags.
Fixes#4659
`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
