From b8bfc44e42a88611be47977c383282fe161490d9 Mon Sep 17 00:00:00 2001 From: Michael Davis Date: Sun, 2 Feb 2025 19:24:13 -0500 Subject: [PATCH] queries: Improve Rust const generic and '_' type highlighting You may pass constants as type arguments the const generics feature. This is used in spellbook for example as a poor man's enum, for example `self.strip_suffix_only::(word, hidden_homonym)`. With this change that `FULL_WORD` part is highlighted as a constant instead of a type. This change also highlight the underscore in type placeholders - this is similar to the highlighting done for bindings in Elixir or Erlang for example. In `Vec<_>` the underscore is highlighted the same as a comment. --- runtime/queries/rust/highlights.scm | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/runtime/queries/rust/highlights.scm b/runtime/queries/rust/highlights.scm index 66a21ffbb..fb363599c 100644 --- a/runtime/queries/rust/highlights.scm +++ b/runtime/queries/rust/highlights.scm @@ -95,8 +95,10 @@ left: (type_identifier) @type.parameter) (optional_type_parameter name: (type_identifier) @type.parameter) -(type_arguments - (type_identifier)) +((type_arguments (type_identifier) @constant) + (#match? @constant "^[A-Z_]+$")) +((type_arguments (type_identifier) @comment.unused) + (#eq? @comment.unused "_")) ; --- ; Primitives
