Embedded Sass Shim for SassC Ruby

Use sass-embedded with SassC Ruby!

This library shims sassc with the sass-embedded implementation.

Which Sass implementation should I use for my Ruby project?

• sass-embedded is recommended for all projects. It is compatible with:
  • dartsass-rails >=0.5.0
  • haml >=6.0.9
  • silm >=5.2.0
  • sinatra >=3.1.0
  • tilt >=2.0.11
• sassc-embedded is recommended for existing projects still using sassc or sprockets. It is compatible with:
  • dartsass-sprockets
  • sassc
  • sassc-rails
  • sprockets
  • sprockets-rails
• sassc is deprecated.
• sass has reached end-of-life.

Install

Add this line to your application's Gemfile:

gem 'sassc-embedded'

And then execute:

bundle

Or install it yourself as:

gem install sassc-embedded

Usage

This shim utilizes sass-embedded to allow you to compile SCSS or SASS syntax to CSS. To compile, use a SassC::Engine, e.g.:

require 'sassc-embedded'

SassC::Engine.new(sass, style: :compressed).render

See rubydoc.info/gems/sassc for full API documentation.

Behavioral Differences from SassC Ruby

1. Option :style => :nested and :style => :compact behave as :style => :expanded.

2. Option :precision is ignored.

3. Option :line_comments is ignored.

See the dart-sass documentation for other differences.

Troubleshooting

The original sassc gem is still being used instead of sassc-embedded

When launching an application via bundle exec, it puts sassc-embedded at higher priority than sassc in $LOAD_PATH. You can verify the order of $LOAD_PATH with the following command:

bundle exec ruby -e 'puts $LOAD_PATH'

If you see sassc has higher priority than sassc-embedded, try remove sassc:

bundle remove sassc

If your application has a transitive dependency on sassc that cannot be removed, you can use one of the following workarounds.

Workaround One

Add this line to your application's Gemfile:

gem 'sassc', github: 'sass/sassc-ruby', ref: 'refs/pull/233/head'

And then execute:

bundle

The fork of sassc at sass/sassc-ruby#233 will load the shim whenever require 'sassc' is invoked, meaning no other code changes needed in your application.

Workaround Two

Add this line to your application's code:

require 'sassc-embedded'
