LibSass

Wrappers

LibSass is just a library. To run the code locally (i.e. to compile your stylesheets), you need an implementer, or "wrapper". There are a number of other wrappers for LibSass. We encourage you to write your own wrapper — the whole point of LibSass is that we want to bring Sass to many other languages, not just Ruby!

Below are the LibSass wrappers that we're currently aware of. Sometimes there are multiple wrappers per language – in those cases, we put the most recently-updated wrapper first.

• Sass C

  SassC (get it?) is a wrapper written in C.

  To run the compiler on your local machine, you need to build SassC. To build SassC, you must have either a local copy of the LibSass source or it must be installed into your system. For development, please use the source version. You must then setup an environment variable pointing to the LibSass folder, for example:

  export SASS_LIBSASS_PATH=/Users/hcatlin/path/libsass
  

  The executable will be in the bin folder. To run it, try something like:

  ./bin/sassc [input file] > output.css
  

• Crystal

  sass.cr is a LibSass wrapper for the Crystal programming language.

• Go

  go-libsass has the most active GoLang wrapper. gosass is another LibSass wrapper.

  C6 is a Sass 3.2 compatible implementation written in pure GoLang that aims to extend Sass. wellington/sass is an in-progress pure Go Sass lexer, parser, and compiler.

• Java

  There is one Java wrapper — jsass. There is also a plugin for Maven — LibSass Maven plugin.

• JavaScript

  The sass.js project makes LibSass available as pure JavaScript. There's a way to test it in the browser, too.

• Lua

  The Lua wrapper is found at lua-sass.

• .NET

  LibSass Host is updated regularly, and is probably the best bet. There's also libsass-net or NSass, although they haven't been updated in a while.

• Node

  The node-sass project has proven to be popular, and we've taken it into the main Sass GitHub repo. Check out its package page here, and there's a dedicated twitter account for updates.

• Perl

  The CSS::Sass project is updated regularly. There's the Text-Sass-XS project, too, although it hasn't been updated in a while.

• PHP

  The SassPHP project is an updated fork of an older PHP version.

• Python

  The libsass-python project is updated regularly. There are more details on its own website.

  Three other Python projects, python-scss, pylibsass and SassPython, haven't been updated in a while.

• Ruby

  LibSass has also been ported back into Ruby for the sassc-ruby project.

• R

  The R Sass package wraps LibSass with additional caching and bundling methods. Extended documentation.

• Rust

  The sass_rs crate is a LibSass wrapper and is updated regularly.

• Scala

  The only Scala project, Sass-Scala, hasn't been updated in a couple of years.
