Daniel Ebert 33d85606cf Add alignment indent queries for binary & ternary expressions in C. 11 months ago
Daniel Ebert 3e79a35656 Align arguments in a function call in C. 
Since the tree-sitter grammar is not very good
at parsing function calls while they're being written,
this is not yet super useful.
However, it prevents the new `hybrid` indent heuristic
from choosing these lines as a baseline, making it
more robust.

Update t32 language queries to version 2.2.1 (#7811) 
Version 2.2.1 of the grammar adds extended support for HLL (C, C++,..)
expressions. Quite a few node types were added, renamed or removed in
the process.

This change brings the highlight queries in sync with the ones found in
the repository of the grammar. The highlighting tests "look" okay after
updating the queries.

Recently, Codeberg had some reliability issues. That is why the language
is now using the mirror repository on GitLab as source instead.

Michael Davis f0b877e258 Tune regex highlights for usage in prompts 
Since regex is almost always injected into other languages,
`pattern_character`s will inherit the highlight for the structure that
injects them (for example `/foo/` in JavaScript or `~r/foo/` in Elixir).
This removes the string highlight when used in the prompt.

We also add `ERROR` node highlighting so that errors in regex syntax
appear in the prompt. This resolves a TODO in the `regex_prompt`
function about highlighting errors in the regex.

inject language based on file extension & shebang (#3970) 
* inject language based on file extension

Nodes can now be captured with "injection.filename". If this capture
contains a valid file extension known to Helix, then the content will
be highlighted as that language.

* inject language by shebang

Nodes can now be captured with "injection.shebang". If this capture
contains a valid shebang line known to Helix, then the content will
be highlighted as the language the shebang calls for.

* add documentation for language injection

* nix: fix highlights

The `@` is now highlighted properly on either side of the function arg.

Also, extending the phases with `buildPhase = prev.buildPhase + ''''`
is now highlighted properly.

Fix highlighting of `''$` style escapes (requires tree-sitter-nix bump)

Fix `inherit` highlighting.

* simplify injection_for_match

Split out injection pair logic into its own method to make the overall
flow easier to follow.

Also transform the top-level function into a method on a
HighlightConfiguration.

* markdown: add shebang injection query
