Added information on how to install from the repositories. Improved the instructions for how to build from source, for those that don't want an ancient version of Kakoune. On Ubuntu 20.04 and earlier, GCC 10 is not the default so we have to explicitly tell `make` to use GCC 10.

Passing large diff buffers via the environment can quickly result in
the error "execve failed: Argument list too long". Use a pipe like
in format.kak
When running | (or <a-|>), Kakoune does not use %arg{@} to populate
"$@" (missing feature?). Work around this by moving %arg{@} to a
temporary register. Apparently $kak_quoted_reg_a will never be an
empty list, so work around that too.
When diff parsing fails, we take care to run "fail" in the calling
client, unlike :format (probably a bug in format.kak).
(This patch is best viewed while ignoring whitespace changes (diff -w))
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.

Mapping in the filetype hook matches others like grep.kak and man.kak.
Since we map in buffer scope, git diff buffers will override diff-jump
with git-diff-goto-source.
This means that the diff-jump binding applies here:
diff -u "$1" "$2" | kak -e 'set buffer filetype diff'

*.ini files traditionally use ; but for example the "foot" terminal's
foot.ini uses #. Add a hack to treat ini files as "conf" filetype
if they contain a #-comment (very slim chance of false positives).
This requires to explicitly set comment_line to the default #,
because we set the "ini" filetype earlier.

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.
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 "+".
