Insert mode completions are accepted by typing any key. For example,
if there is a completion "somefunction()", then typing
some<c-n>;
will insert
somefunction();
and then the InsertCompletionHide hook will fire. The hook parameter
is a range that contains the entire thing: the actual completion plus
the trailing semicolon that closed the completion menu.
The [original motivation] for the hook parameter was to support
removing text inserted by completion, so we can apply text edits
or expand snippets instead. One problem is that we don't want to
remove the semicolon. Another problem came up in a discussion
about [snippets]: let's say we have a snippet "add" that expands to
add(?, ?)
where ? are placeholders. After snippet expansion the cursor replaces
the first placeholder. If I type "ad<c-n>1" I expect to get "add(1, ?)".
If the InsertCompletionHide hook only runs after processing the "1"
keystroke, this is not possible without evil hacks.
Fix these problems by running InsertCompletionHide when a completion is
accepted _before_ inserting anything else into the buffer. This should
make it much easier to fully implement [LSP text edits]. I doubt
that anyone besides kak-lsp is using the hook parameter today so this
should be a low-risk fix.

Some languages have a trim-indent command but don't use it (for no
apparent reason). Make them trim trailing spaces when exiting insert
mode, like most other languages support scripts do.
This approach is not very elegant as it hooks into the event manager
deep inside the call graph, but solves the exiting issue and is an
okay stop gap solution until a better design comes up.
Fixes#4605
Deleting a buffer resets normal mode on all clients that were
displaing that buffer, but ScopedForceNormalMode that are used
from user mode do not take this possiblity into account on
destruction, which leads to deleting the last normal mode from
the context, ending up with an empty mode stack.
Fixes#3909
As pointed out in [1], when insert mode autocomplete is disabled,
<c-n> could be used to activate insert mode completions temporarily
[2]. This regressed in 6f7c5aed (Do not show custom completions when
autocomplete is off, 2022-01-03). Fix this by enabling completions
on <c-n>/<c-p>. This allows us to remove a special case for explicit
completers.
Alternative behavior (future?): make <c-n> toggle completion like
<c-o>. This can be done today, as suggested by Screwtape on IRC:
map global insert <c-n> %{<c-o><c-n><a-;>:toggle-ctrl-n<ret>}
define-command toggle-ctrl-n %{
hook global InsertCompletionShow .* %{ map window insert <c-n> <c-n> }
hook global InsertCompletionHide .* %{ unmap window insert <c-n> <c-n> }
}

[2] <c-n> completion only lives for the lifetime of the completion
menu, whereas <c-o> lasts until you exit insert mode. This means
that autocompletion is much more convenient than <c-n> or <c-x>f,
because those require an explicit completion request for each
path component.
The ThreadedRegexVM implementation does not execute split opcodes as
expected: on split the pending thread is pushed on top of the thread
stack, which means that when multiple splits are executed in a row
(such as with a disjunction with 3 or more branches) the last split
target gets on top of the thread stack and gets executed next (when the
thread from the first split target would be the expected one)
Fixing this in the ThreadedRegexVM would have a performance impact as
we would not be able to use a plain stack for current threads, so the
best solution at the moment is to reverse the order of splits generated
by a disjunction.
Fixes#4519
This will unfortunately break some use case which will require
using wrapper scripts to add the necessary newline. It is however
harder to do the contrary, and it makes a lot of other use case
possible, such as checksuming.
Fixes#3669
As reported in [1], completions provided by "set global completers
option=my_completion" activate insert mode autocompletion, even when
the autocomplete option does not have the insert mode flag.
This happens because InsertCompleter::on_option_changed() calls
InsertCompleter::setup_ifn(), which shows the completion pager.
Fix this by computing whether the completion pager is enabled;
otherwise we can return early from setup_ifn().
The completion pager is enabled if the autocompletion bit is set,
or if the user has requested explicit completion.

Now that it is, we get the following error when trying to execute
`test/compose/select-display-columns`
```sh
./enabled: 2: [: 4: unexpected operator
```
This commit fixes the enabled check
trim_indent call was incorrect, trim_indent is intended to work
on multi-line strings and trims trailing whitespace as well (could
benefit from a better name).
Fixes#4378
Add support for a third color in face definition that controls
the underline and a 'c' attribute for curly underline (that takes
precedence over 'u' if both are specified)
Allow empty colors to mean default, so that `,,red+u` means the
same as `default,default,red+u`
Fixes#4138
Correctly indentint on "end" keyword seems very hard,
it is simpler to remove it. And we already insert "end"
in ruby-insert-on-new-line hook, so the removal shouldn't
hurt too much.
Function taking a parameter with a struct tag on the last line
before the opening { were wrongly treated as structs. Add some
additional regex logic to try to catch those cases.
Fixes#4136
When a replaced buffer range atom was starting exactly at the
location we wanted to split onto the code would split *after*
that atom instead of before.
Fixes#4052
Triple strings are now distinct from docstrings, triple strings
only preceeded by blanks on the line are considered docstrings.
Avoid highlighting of the closing marker using a lookahead, this
is not fully correct as it will break on a double quote triple
docstring containing a single quote triple string but that seems
improbable enough; if we encounter this in the wild we can split
the two docstring formats into separate regions.
I removed files which are no longer significant (ui-in, ui-out, selections,
state), added new files which are now important (enabled, script, kak_*),
and reordered the files to reflect the order in which they are applied -
in particular, cmd is applied *after* the input is read.
When doing line completion, we previously used to not complete the line
if it had different indent to the potential completion.
This commit changes the behaviour to ignore indentation when completing lines.
Giving an explicit register uses its content for the default value
to use if the user does not enter anything. This enables:
`set-register a %{commands}; execute-keys '"a:<ret>'`
`set-register a %{shell script}; execute-keys '"a|<ret>'`
...
This provides a nice way to avoid the need to escape keys to use
those normal mode commands.
Fixes#3825
Because no flags were set for regex matching, the regex engine was
assuming that the subject string past-the-end matched a end-of-line.
As the subject string already ended with a \n character, the regex
engine processing of the "past-the-end" position would match '^$'
as ^ matched past the existing \n and $ matched the assumed
end-of-line.
Fixes#3799
Use the custom object match command for copying indentation of blocks,
rather than simply increasing/decreasing indentation when start and end
statements are encountered.
This fixes an issue where a newline added after an already correctly
placed `else` or `fi` would trigger an unnecessary deindent. Tests have
been added to ensure no regression in this behaviour.

Based on c-family block comment handling, this patch also add rust
block comment indentation.
This affects `o` behavior on empty comment but it allows a way more
efficient way to clear comments.
