Questions

Currently in the dependencies file jekyll-sass-converter is still version 1.5.2 but the current version available is 2.1.0, my question is why hubot haven't bump to the new version ?
Is there dependencies issues ? Where can I find theses info ?

I just see that's related to this hubot PR #749
But I can't see the errors, I get Error: We are currently unable to download the log. Please try again later.

Can someone re-run the checks ? @yoannchaudet @parkr

@BenSouchet Jekyll 3.x does not support jekyll-sass-converter 2.0:

Fetching gem metadata from https://rubygems.org/.........
Resolving dependencies.....
Bundler could not find compatible versions for gem "jekyll-sass-converter":
  In Gemfile:
    github-pages was resolved to 223, which depends on
      jekyll-sass-converter (= 2.1.0)

    github-pages was resolved to 223, which depends on
      jekyll (= 3.9.0) was resolved to 3.9.0, which depends on
        jekyll-sass-converter (~> 1.0)

Based on this, you can see that Jekyll 3.9.0 requires jekyll-sass-converter 1.x only. Jekyll would need to release a 3.10 which allows jekyll-sass-converter 2.0.

@parkr Okay, have you the ability to push in that direction, I know there is very little chance that it will be done but it doesn't cost much to try because the current situation is blocked.

We will have finally the chance to use Dart Sass implementation, I hope (since all implementations are deprecated 😞 ) but jekyll-sass-converter current version is 2.1.0 so Jekyll would not take it into account knowing that it still uses version 1.5.2. It's currently a dead-end.

Creating this version 3.10.0 would offer the possibility to unblock the situation, I guess it's not top priority but if you can push in that directly it would be so cool.

Thanks.

It's not an easy process, but I'm going to spend a little time on it here: jekyll/jekyll#8939

@parkr Thanks you ❤️

We will have finally the chance to use Dart Sass implementation

jekyll-sass-converter v2.1.0 uses sassc, which uses libsass under the hood. https://github.com/sass/sassc-ruby

The Dart-Sass implementation does not yet have a stable release, so it wouldn't be wise to release it to GitHub Pages before it's considered stable. Additionally, the sass-embedded gem has a runtime dependency on google-protobuf which can be challenging to install for folks.

If you want to use this soon, I'd really recommend adding a precompile step to use the sass script provided by dart-sass: https://github.com/sass/dart-sass/releases. With Pages on GitHub Actions in the works, you'll be able to customize your builds so you will be able to easily add the compilation step before running jekyll build and publishing your site. 🔜

@parkr
Hi 👋, your last paragraph seems great news, if I understand correctly "soon" we will be able to customize the Github Pages actions so we will be able to add the "sass to css" (using Dart Sass) ourself 🤔

But just to come back to the topic, the idea was (at least in my head):

1. Create a new 3.x release of Jekyll to support jekyll-sass-converter 2.x (that was you did here 3.x: jekyll-sass-converter 2.x support jekyll/jekyll#8939 )
2. Update github-pages to use the latest version available of jekyll-sass-converter (that why I opened this issue)
3. Release a new version of jekyll-sass-converter with the option to select the Dart implementation to use, embedded-sass refers to Dart Sass and was added by ntkme. I try to push for this to happen here: Time for a new release jekyll/jekyll-sass-converter#122

And since 5 days ago, the Dart Sass as stable version available 🎉, you can also check here, I still think that releasing the Dart Sass option with a new release of jekyll-sass-converter would be the best option so everyone using Github Pages can use the current (not deprecated) version of Sass with all the amazing features, because the last version of Sass we can use in more than 2 year old, so every features /bug fix,... added to Sass for the last 2 years isn't available.

In either way, @parkr thanks for the work you do and the time you took reading my messages 😊 and trying to fix the Sass dead-end Github Jekyll is currently.

PS: Even if the current Dart Sass implementation wasn't 100% stable knowing that to use it the user has to edit his _config.yaml file to choose to use this implementation I don't think it is really annoying (and the user can edit back his _config.yaml file to use back the default sassc impl. in case he as issues, or report them to the github repo.)

@parkr Both dart-sass-embedded and sass-embedded gem are now on stable release. We just had a release cut for jekyll-sass-converter 2.2.0.

Regarding the concern about protobuf, I would say the compatibility is actually very good, which you can see from this test matrix. It works for MRI >=2.6 and JRuby on mac, linux, and windows. Only compatibility issue I found so far is that protobuf sometimes causes crashes in TruffleRuby, but that appears to be a problem of TruffleRuby itself.
