The last update is from 2017, it's pretty outdated. Current
support was combined from existing languages such as Ruby and
Zig and tweaked to fit the Pony language.
The current handling of preprocessor directives in filetype/c-family.kak
leads to a wall of solid colour for more complicated #if or #define
directives, although #include is already nicely highlighted.
Instead of highlighting an entire directive with the meta face, highlight
just the #define, #if or #elif keyword as meta, treating the rest of the
directive as normal c-family expressions. This significantly improves
the readability of complex macro definitions.
For directives other than #define, #if and #elif, we treat the rest of
the directive as an opaque string in normal face rather than trying to
highlight it, covering cases like #error, #pragma, etc. where the rest
of the line is an error message string or other non-expression content.
This does the right thing for #ifdef and #ifndef too, as we don't highlight
identifiers in c-family text so their arguments should be normal face
anyway.
We already pull in the diff module in mail.kak to enable the nice
:diff-jump behaviour on inline patches. Also enable the shared/diff/
highlighter underneath our shared/mail/ highlighter for inline diffs,
listing it first so mail patterns take precedence over diff patterns.
De-emphasise signatures including the standard '^-- \n' separator in the
same way as quoted text in a reply.
Fixes: https://github.com/mawww/kakoune/issues/4998
prompt has fuzzy filtering which is more discoverable than the menu
mode's regex filtering (because that one needs / to trigger it).
There are no important differences left, so replace the menu builtin
with a prompt-based command.
prompt does not support markup in the completion menu, so drop that
feature for now.
This makes Kakoune behave more consistently when using it for Zig.
Empty comments are already auto-removed from the C-family and Python.
In this PR, string literals that start with \\ are not removed in purpose.
This continues the work started by 0a9c90fec (rc: use a separate
*-insert hook to auto-insert comments, 2021-04-17).
The one that's left is Rust but that one is trickier.
