In JumpToMatchingBrace, the loop should stop immediately after finding the matching bracket.
It causes multiple jumps in certain situations:
`(I [ ]{ }) => ( I[ ]{ })`
Fix the regression after 3b34a02: setting readonly option to true
in onBufferOpen lua callback doesn't work, since it is automatically
reset to false if write permission is not denied.
Added tabbar.active color group for displaying the name of the active
tab in the tabbar with different colors.
If tabbar.active is not defined in the colorscheme, the active tab name
is displayed with the same colors as inactive ones.
Ref #1646
Fix the following bugs:
- If a split pane is not at the left edge of the screen, the statusline
with suggestions for it is displayed at wrong place.
- When keymenu is enabled, the statusline with suggestions is not
displayed at all.
Don't highlight things that don't exist, add some missing keywords,
highlight true/false/nil as constants instead of keywords, and
highlight types as types instead of constants.
- move type cast keywords into operators, since that's their syntactic function
- fix a single dot being matched as a constant.number
- add the missing caret operator
* Overall syntax highlighting improvements for C++
Most of these changes are based on the information on cppreference.com;
specifically from here: https://en.cppreference.com/w/cpp/keyword
- made `identifier` actually match any identifier
- add ~ as an operator
- add `static_assert` as a keyword (statement)
- add keywords that are interchangeable with operators as operators
- add keywords `sizeof`, `alignof` and `typeid` as operators
- add the quasi-keywords `asm`, `fortran` and `final`, `override`
- add the keyword `nullptr`
- add `_Pragma` as a preprocessor keyword
- add C++20 (concepts and modules) -related keywords
- add casting keywords
- add the keyword (specifier) `noexcept`
- remove `nothrow` (because it's not any more special than `vector` is)
- add `wchar_t` and `charXX_t` types
- add cv type keywords as `type.keyword`s
- move some fitting keywords into `type.keywords`
(mostly because they appear in/near type signatures etc.)
I didn't include coroutine-related language features,
primarily because there is no good source of information
about them other than the ISO C++ standard.
* Further changes to C++ syntax highlighting
- reverted the changes to the `identifier` regex, since most
colorschemes color it the same as `type`s and/or `statement`s
- fix the 2nd `type` regex (the word boundaries were in only two pipe-options)
- move `nullptr` back into `constant.bool`,
since it looks better in-editor this way (imo)
- add `?` as an operator
- add regexes that match all the correct number literals, and nothing else
(see https://en.cppreference.com/w/cpp/language/floating_literal)
(that is, if I haven't made a mistake)
