# Overview

This is a work-in-progress language server for Sass written in Dart to
use [sass_api](https://pub.dev/packages/sass_api).
It uses [the language server protocol](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.18/specification/#languageFeatures) (LSP).

## Status

[Development of new features is paused](https://github.com/sass/dart-sass/issues/2476). See the Issues and Pull request tabs for planned and partially implemented features.

The [Testing and debugging](docs/contributing/testing-and-debugging.md) docs explain how to run the language server from source code.

These features are implemented:

## How to contribute

See [Contributing](./CONTRIBUTING.md), but note that the parser currently requires a valid Sass document to generate an AST ([sass/dart-sass#2476](https://github.com/sass/dart-sass/issues/2476)).
