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:
grass experimentally releases a
WASM version of the library to npm,
compiled using wasm-bindgen. To use grass in your JavaScript projects, just run
npm install @connorskees/grass to your package.json. Better documentation
for this version will be provided when the library becomes more stable.
The large features remaining are
builtin functions min, max
@extend (~600 tests)
indented syntax (27 tests)
css imports
@use and module system (~1200 tests)
@forward (~400 tests)
@keyframes (~30 tests)
@supports (~128 tests)
(enabled by default): build a binary using clap
(enabled by default): enable the builtin functions random([$limit]) and unique-id()
In the future this feature will be removed when it is no longer necessary to rely on rand for
random numbers.
As much as possible this library attempts to follow the same philosophy for testing as
rust-analyzer.
Namely, all one should have to do is run cargo test to run all its tests.
This library maintains a test suite distinct from the sass-spec, though it
does include some spec tests verbatim. This has the benefit of allowing tests
to be run without ruby as well as allowing the tests more granular than they
are in the official spec.
Having said that, to run the official test suite,
bash
git clone https://github.com/connorskees/grass --recursive
cd grass
cargo b --release
./sass-spec/sass-spec.rb -c './target/release/grass'
These numbers come from a default run of the sass specification as shown above.
