Distinction between line comments and block/doc comments

[dssgabriel]

Hello helix community!
I've looked around the documentation and the repo but I wasn't able to find how to configure helix to make a distinction between single-line comments and block/documentation comments.
This a snippet from my theme configuration (which is correctly loaded):

"comment.block.documentation" = "light-gray"
"comment.block" = "light-gray"
"comment" = "gray"

[palette]
gray = "#3d3837"
light-gray = "#413c3a"

However, when I have two different types of comments in a file, there is no color difference as you can see from these screenshots of C and Rust code:


I've seen that when adding languages to helix, it is possible to define "comment tokens". Is it also possible to create "comment block/doc tokens" so that the editor can display them differently depending on the user's configurations?

Thanks in advance!

A good example for something similar is #1618. The theming you have looks good but the highlight queries for languages with block comments need to be captured in a way that can be themed like that. For example, this rust query line could be changed into

((line_comment) @comment.documentation
 (#match? @comment.documentation "^///"))
(line_comment) @comment.line
(block_comment) @comment.block

Themes that have a comment.block would style the block comments differently and themes without would fall back to whatever is defined for comment.

Thank you for your answer! I'll try and modify the relevant .scm files (need to dig a bit into Tree-sitter documentation first) and I might make a PR for those.
