Crate rsass

Sass reimplemented in rust (not yet complete).

The “r” in the name might stand for the Rust programming language, for “re-implemented”, or possibly for my name Rasmus.

Example

use rsass::{compile_scss_path, output};

let path = "tests/basic/14_imports/a.scss".as_ref();
let format = output::Format {
    style: output::Style::Compressed,
    .. Default::default()
};
let css = compile_scss_path(path, format).unwrap();

assert_eq!(css, b"div span{moo:goo}\n")

Sass language and implemetation status

The sass language is defined in its reference doc. This implementation is incomplete but getting there, if slowly.

Progress: 4002 of 6180 tests passed in dart-sass compatibility mode.

If you want a working rust library for sass right now, you may be better of with sass-rs or sass-alt, which are rust wrappers around libsass. Another alternative is grass which is another early stage pure rust implementation. That said, this implementation has reached a version where I find it usable for my personal projects, and the number of working tests are improving.
