ae001a1f91 Run EventManager whenever writing to a file descriptor would block
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.

987e367955 Work around incomplete std::to_chars() support in libstdc++ 10
Ubuntu 20.04 ships GCC's libstdc++ 10 from 2020 which implements
std::to_chars() for integers but not for floats. Use the float overload
only if the library advertises support via the feature testing macro.

This can be removed once we require GCC 11 (see
https://www.gnu.org/software/gcc/gcc-11/changes.html).

8a7109f9c5 Fix compilation due to failing template deduction for aggregates
gcc 11.2.0 compiles us just fine but clang 13.0.1 fails with this error

	clang++ -DKAK_DEBUG -O0 -pedantic -std=c++2a -g -Wall -Wextra -Wno-unused-parameter -Wno-sign-compare -Wno-address -frelaxed-template-template-args -Wno-ambiguous-reversed-operator -MD -MP -MF .ranges.debug.d -c -o .ranges.debug.o ranges.cc
	ranges.cc:30:17: error: no viable constructor or deduction guide for deduction of template arguments of 'Array'
	    check_equal(Array{{""_sv, "abc"_sv, ""_sv, "def"_sv, ""_sv}} | flatten(), "abcdef"_sv);
	                ^
	./constexpr_utils.hh:14:8: note: candidate template ignored: couldn't infer template argument 'T'
	struct Array
	       ^
	./constexpr_utils.hh:14:8: note: candidate function template not viable: requires 0 arguments, but 1 was provided
	1 error generated.

The same error can be reproduced with this C++ input

	template<typename T, int N>
	struct Array
	{
	    T m_data[N];
	};
	void test() {
	    (void)Array{{1, 2}};
	}

Since "Array" has no constructor, the compiler uses aggregate
initialization. Only recent g++ seems to be smart enough to deduce
template arguments in this case. Help other compilers by adding a
deduction guide. The deduction guide needs to count the array elements
to infer the array size, hence we need to remove braces. Happily,
this is allowed and it's also what std::array does.

90db664635 Fix crash when deleting a buffer from a user mapping
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.

f709ba6390 Fix buffer overflow in parse_quoted
This fixes a crash when using kak-lsp with bash-language-server.  The
issue is that the second read() in parse_quoted may read past the end of
the string.  If this happens and the condition on line 126 is false,
then the loop on line 119 will continue to read past the end of the
buffer since it checks for state.pos != end instead of state.pos < end,
which will likely result in a crash.  The fix is to add a check for the
buffer end before the second read. The added test fails without the
change and passes with the change.

e6d0ff1bc8 Filter duplicate completions only if they have the same select cmd
Given a completer option with two applicable completions

	text|select-cmd1|menu-text1
	text|select-cmd2|menu-text2

Kakoune will only show one of them, because they will insert the
same text.

Some language servers send completions like this, for example if
two different importable modules provide the same name. This can be
reproduced using intelephense in this PHP file (cursor is %())

	<?php
	namespace namespace1;
	class sometype {}
	?>
	<?php
	namespace namespace2;
	class sometype {}
	?>

	<?php
	namespace test;
	some%()
	?>

Both completions insert "sometype". The import statement will be
added in an InsertCompletionHide hook by kak-lsp (it uses select-cmd
to determine which completion was selected).

To support this use case, refine the duplicate detection to not filter
out completions with different select-cmd values.

3abf2b8260 Faces: Check that underline colour comes before base/attributes markers
Parsing a (non-valid) font with a comma in the name of the base colour
makes Kakoune crash. It is not a valid face, but Kakoune should just
return an error message instead.

Reproducer:

    :set-face global foo ,red@,blue

Note the comma "," after the "@". This is not a valid base name, and it
leads to a crash. Let's see what happens.

At the beginning of parse_face(), we have the following code:

    auto bg_it = find(facedesc, ',');
    auto underline_it = bg_it == facedesc.end() ? bg_it : std::find(bg_it+1, facedesc.end(), ',');
    auto attr_it = find(facedesc, '+');
    auto base_it = find(facedesc, '@');
    [...]
    auto colors_end = std::min(attr_it, base_it);

After this:

- bg_it points to ",red@,blue"
- bg_it != facedesc.end(), so we have underline_it pointing to the first
  comma after bg_it. This means that underline_it points to ",blue"
- base_it points to "@,blue"
- attr_it points to the end of facedesc (no "+" marker), so colors_end
  points to base_it, "@,blue"

Later in the code, just after parsing the foreground and background
colours, we have:

    if (underline_it != facedesc.end())
        face.underline = parse_color({underline_it+1, colors_end});

When passing {underline_it+1, colors_end} to parse_color(), we pass in
fact iterators pointing to {",blue", "@,blue"}. Because the second one
starts _before_ the first one in the string, this means that the
resulting string is considered to have a _negative_ length.
parse_color() passes the string to str_to_color(), who fails to turn up
the colour, and attempts to throw:

    throw runtime_error(format("unable to parse color: '{}'", color));

The variable "color" still has this negative length, and this goes all
the way down to an assert in src/units.hh where we expect that string to
be >= 0, and we crash on the assertion failure.

For similar reasons, we also get a crash if the comma comes after the
marker for the face attributes:

    :set-face global foo ,red+,a

To fix both cases, let's add a check to make sure that the underline_it,
marked with a comma, never gets detected as present and pointing after
colors_end, be it "@" or "+".

43fc5b0078 Make <c-n> show completion menu again when autocomplete is off
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> }
	}

[1] https://github.com/mawww/kakoune/pull/4493#issuecomment-1031189823
[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.

33e81af0f3 Fix regex alternation execution priority
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.

6f7c5aed10 Do not show custom completions when autocomplete is off
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.
