LibSass deprecated in October 2020

[CarterPape]

The Sass implementation on which this gem is based was deprecated October 2020. Again.

Although there is not yet any deprecation warning that prints to announce this deprecation, I figured it might be good to get ahead of the warning and put an issue in about this.

I've forked this repo and will dabble with potential solutions, but I am not a regular contributor and don't program for a living, so it might be ugly.

Looks like Dart Sass is the new Sass implementation, no clue how easy it would be to use it instead.

Figuring out why @use wasn't working lead me here.

I was looking around for potential solutions and approches for upgrading sass.
Seems like the dependency we have currently is jekyll/jekyll-sass-converter -> sass/sassc-ruby -> sass/libsass.

The interoperability between sassc-ruby ( Ruby ) & libsass ( C ) is achieved by ffi/ffi. FFI supports native C types along with structs, enums etc. We need something similar for interoperability between Ruby & Dart. I tried searching for libraries that support this but was unsuccessful.

Apparently Dart Sass is also distributed as a pure Javascript NPM package, which might be another option.

This looks most promising to me. It is compiled from the Dart Sass implementation, which is the "reference implementation of Sass". I have an easier time wrapping my head around an NPM dependency than I do a standalone Dart executable.

There are sass/embedded-protocol and sass/dart-sass-embedded which can be used to create language bindings for sass/dart-sass by launching a separate compiler process and communicating via stdio. I created sass-embedded as a host implementation for Ruby.

Update: The support for sass-embedded has been release with jekyll-sass-converter 2.2.0. Instruction is available here: https://github.com/jekyll/jekyll-sass-converter#sass-embedded

Note: This won't work out of box on GitHub Pages as it still runs Jekyll 3.x, you will have to use a custom action to build your pages with Jekyll 4.x.

Is there any chance that above fix getting merged? This repo haven't had much activity in the last 12+ months.

It looks like both sass/embedded-protocol and sass/dart-sass-embedded are stable enough to start using. Is that a valid assumption? If so, I'm happy to coordinate getting a PR merged and a release done to address the libsass deprecation.

[phisch]

There are no stable realeases for them yet:
https://github.com/sass/embedded-protocol/releases
https://github.com/sass/dart-sass-embedded/releases

It might make sense to create a PR for it now, and do some early testing. But block the merge until a stable release is published and the PR was tested with it.

edit: just saw that's exactly what ntkme already said above.

[ntkme]

@mattr- @phisch I just opened a draft PR #124 so that we can start the review process and work on changes.

[ntkme]

@vikashd @emcoding @imustafin Thanks for trying things out. Now #124 has been merged into this repository, you should update your projects to use this project instead of my fork.

[phisch]

This has been merged for a while now, so is there a plan to make a new release anytime soon?

I received an error using the CSS vanilla-framework that Ubuntu uses; I assume it is because of libsass beind deprecated.

my _global_functions.scss is using @use 'sass:math'; and the deprecated LibSass doesn't make use of the use statement according to a StackOverflow article from late 2021.

The issue might be because there's still an open issue for GitHub pages gem which is using a deprecated version of jekyll-sass-converter (1.5.2): github/pages-gem#813
