Problem: calling `vim.filetype.match()` has performance bottleneck in
that it has to match a lot of Lua patterns against several versions of
input file name. This might be the problem if users need to call it
synchronously a lot of times.
Solution: add "parent pattern pre-matching" which can be used to quickly
reject several potential pattern matches at (usually rare) cost of
adding time for one extra Lua pattern match.
"Parent pattern" is a manually added/tracked grouping of filetype
patterns which should have two properties:
- Match at least the same set of strings as its filetype patterns.
But not too much more.
- Be fast to match.
For them to be effective, group should consist from at least three
filetype patterns.
Example: for a filetpye pattern ".*/etc/a2ps/.*%.cfg", both "/etc/"
and "%.cfg" are good parent patterns (prefer the one which can group
more filetype patterns).
After this commit, `vim.filetype.match()` on most inputs runs ~3.4
times faster (while some inputs may see less impact if they match
many parent patterns).
Problem:
When there are multiple inlay hints present at the same position, they
should be rendered in the order they are received in the response from
LSP as per the LSP spec. Currently, this is not respected.
Solution:
Gather all hints for a given position, and then set it in a single
extmark call instead of multiple set_extmark calls. This leads to fewer
extmark calls and correct inlay hints being rendered.
**Problem:** A query file for something like `html_tags` will not be
given html node completion
**Solution:** Check for parser aliases before offering completions

Problem: due to single list of sorted patterns, their matching inside
`vim.filetype.match()` was done very similarly but with extra checks
to stop processing negative priority patterns before extensions.
Solution: create separated sorted lists for patterns with non-negative
and negative priorities. This allows to process them in a single
extracted function making the main codeflow a bit nicer and more
easily expandable.
Problem: filetype: htmlangular files are not properly detected
Solution: Use the new htmlangular filetype for angular files, because
since angular v17, those are no longer valid HTML files.
(Dennis van den Berg)
Since Angular 17, the new Control Flow Syntax is not valid HTML. This PR
adds a new filetype detection for the HTML templates of Angular.
It first checks the filename. The Angular convention is to use
*.component.html for the template. However, this is not mandatory.
If the filename does not match, it will check the contents of the file
if it contains:
- One of the Control-Flow blocks: @if, @for, @switch, @defer
- A structural directive: *ngIf, *ngFor, *ngSwitch, *ngTemplateOutlet
- Builtin Angular elements: ng-template or ng-content
- String interpolation: {{ something }}
This enables the Angular LSP to attach only to htmlangular filetypes, as
well as language parsers, such as tree-sitter.

Problem: `vim.filetype.match()` tries to match on contents even if there
is no contents (empty buffer or `{''}` explicit contents).
This results in extra avoidable execution duration for cases.
It matters, for example, when trying to match filetype based solely
on file name (which still needs `contents` or `buf` to properly match
earlier in the code path).
Solution: skip matching based solely on contents if it is `{''}`. This
works because:
- Matching solely on content is done after any user-configured
`vim.filetype.add()` hooks.
- All default matching on content might depend on supplied path
*only* if there is non-empty content (like in
`require('vim.filetype.detect').match_from_hashbang()`).
Problem:
Exiting the insert mode with ctrl-c does not trigger InsertLeave
autocmd. This may lead to nil error in treesitter foldexpr.
Solution:
Check nil. Folds still can be stale after exiting the insert mode with
ctrl-c, but it will be eventually updated correctly.
An alternative solution would be to ensure that exiting the insert mode
always triggers do_foldupdate. This can be done either by "fixing"
ctrl-c or with on_key callback that checks ctrl-c (nvim-cmp does this).
Problem: not possible to assign priority when defining a sign
(Mathias Fußenegger)
Solution: Add the priority argument for the :sign-define ex command and
the sign_define() function (LemonBoy)
Use the specified value instead of the default one (SIGN_DEF_PRIO) when
no priority is explicitly specified in sign_place or :sign place.

Problem: the code and docs for vim.diagnostic.JumpOpts.float send mixed
signals about what the default should be. When the option is first set,
in the global_diagnostic_options table, the comment clearly says that
the default is false. Later in the code, in goto_diagnostic, there's
a line that sets the default to true if no default is present. Finally,
the docs say that the default is true.
Solution: Change the docs to reflect the new default of false and fix
the goto_diagnostic function.
Problem:
Error when calling vim.treesitter.start() and vim.treesitter.stop() in
init.lua.
Solution:
Ensure syntaxset augroup exists after loading synload.vim.
