tree-sitter-scss-modern

A tree-sitter grammar for current SCSS syntax.

This project is a maintained fork of tree-sitter-grammars/tree-sitter-scss, licensed under MIT. It adds the Sass module system (@use and @forward options), maps, variable flags, boolean operators, and other current syntax the original does not parse, keeping the original's node kinds.

Using it

cargo add tree-sitter tree-sitter-scss-modern

let mut parser = tree_sitter::Parser::new();
let language = tree_sitter_scss_modern::LANGUAGE;
parser
    .set_language(&language.into())
    .expect("Error loading current SCSS syntax parser");

npm install tree-sitter-scss-modern

import Parser from 'tree-sitter';
import Language from 'tree-sitter-scss-modern';

const parser = new Parser();
parser.setLanguage(Language);

A GitHub Packages copy is also published as @meloncholera/tree-sitter-scss-modern.
