It looks like c-ts-mode thinks type qualifiers are possible only in
C++?
:feature 'type
`((primitive_type) @font-lock-type-face
(type_identifier) @font-lock-type-face
(sized_type_specifier) @font-lock-type-face
,@(when (eq mode 'cpp) <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
'((type_qualifier) @font-lock-type-face
(qualified_identifier
scope: (namespace_identifier) @font-lock-type-face)
(operator_cast) type: (type_identifier) @font-lock-type-face))
[,@c-ts-mode--type-keywords] @font-lock-type-face)
The tree-sitter library returns a type_qualifier node for 'restrict':
(parameter_declaration type: (type_identifier)
declarator:
(pointer_declarator *
(type_qualifier restrict)
declarator: (identifier)))
Yuan, can you look into fixing this, please?
