An implementation of the SASS spec in pure Rust
This crate aims to provide a high level interface for compiling SASS into plain CSS. It offers a very limited API, currently exposing only 2 structs.
In addition to a library, also included is a binary that is intended to act as an invisible replacement to the sass commandline executable.
This crate aims to achieve complete feature parity with the dart-sass reference implementation. A deviation from the dart-sass implementation can be considered a bug except for in the following situations: - Error messages - Error spans - Certain aspects of the indented syntax - Potentially others in the future
The large features remaining are
all builtin selector functions (274 tests)
builtin functions content-exists, min, max
@extend (~600 tests)
indented syntax (27 tests)
a special parser for plain css
@use and module system (~1200 tests)
@forward (~400 tests)
@keyframes (~30 tests)
@supports (~128 tests)
To run the official test suite,
bash
git clone https://github.com/connorskees/grass
cd grass
git submodule init
git submodule update
cargo b --release
./sass-spec/sass-spec.rb -c './target/release/grass'
