A [Dart](https://www.dartlang.org) implementation of
|
|
|
|
|
[Sass](http://sass-lang.com/).

## Using Dart Sass
|
|
|
|
|
|
|
|
|
|
Dart Sass isn't ready for distribution yet, but it's possible to test it out by
|
|
|
|
|
running from source. This assumes you've already checked out this repository.
|
|
|
|
|
|
|
|
|
|
1. [Install Dart](https://www.dartlang.org/install). If you download it
|
|
|
|
|
manually, make sure the SDK's `bin` directory is on your `PATH`.
|
|
|
|
|
|
|
|
|
|
2. In this repository, run `pub get`. This will install Dart Sass's
|
|
|
|
|
dependencies.
|
|
|
|
|
|
|
|
|
|
3. Run `dart bin/sass.dart path/to/file.scss`.
|
|
|
|
|
|
|
|
|
|
That's it!
|
|
|

## Goals
|
|
|
|
|
|
|
|
|
|
Dart Sass is intended to eventually replace Ruby Sass as the canonical
|
|
|
|
|
implementation of the Sass language. It has a number of advantages:
|
|
|
|
|
|
|
|
|
|
* It's fast. The Dart VM is highly optimized, and getting faster all the time
|
|
|
|
|
(for the latest performance numbers, see [`perf.md`][perf]). It's much faster
|
|
|
|
|
than Ruby, and not too far away from C.
|
|
|
|
|
|
|
|
|
|
* It's portable. The Dart VM has no external dependencies and can compile
|
|
|
|
|
applications into standalone snapshot files, so a fully-functional Dart Sass
|
|
|
|
|
could be distributed as only three files (the VM, the snapshot, and a wrapper
|
|
|
|
|
script). Dart can also be compiled to JavaScript, which would make it easy to
|
|
|
|
|
distribute Sass through NPM or other JS package managers.
|
|
|
|
|
|
|
|
|
|
* It's friendlier to contributors. Dart is substantially easier to learn than
|
|
|
|
|
Ruby, and many Sass users in Google in particular are already familiar with
|
|
|
|
|
it. More contributors translates to faster, more consistent development.
