jekyll
Saas `@import` is deprecated
This page from Sass documentation announced that usage of @import is deprecated: https://sass-lang.com/blog/import-is-deprecated.
The current theme however is still using this deprecated rule. When executing jekyll build, the warning the deprecation of the said rule is described where the source file for sass files is not present where it is installed.
I have this original Gemfile from fresh installation of jekyll project:
source "https://rubygems.org"
# Hello! This is where you manage which Jekyll version is used to run.
# When you want to use a different version, change it below, save the
# file and run `bundle install`. Run Jekyll with `bundle exec`, like so:
#
# bundle exec jekyll serve
#
# This will help ensure the proper Jekyll version is running.
# Happy Jekylling!
gem "jekyll", "~> 4.3.4"
# This is the default theme for new Jekyll sites. You may change this to anything you like.
gem "minima", "~> 2.5"
# If you want to use GitHub Pages, remove the "gem "jekyll"" above and
# uncomment the line below. To upgrade, run `bundle update github-pages`.
# gem "github-pages", group: :jekyll_plugins
# If you have any plugins, put them here!
group :jekyll_plugins do
gem "jekyll-feed", "~> 0.12"
end
# Windows and JRuby does not include zoneinfo files, so bundle the tzinfo-data gem
# and associated library.
platforms :mingw, :x64_mingw, :mswin, :jruby do
gem "tzinfo", ">= 1", "< 3"
gem "tzinfo-data"
end
# Performance-booster for watching directories on Windows
gem "wdm", "~> 0.1", :platforms => [:mingw, :x64_mingw, :mswin]
# Lock `http_parser.rb` gem to `v0.6.x` on JRuby builds since newer versions of the gem
# do not have a Java counterpart.
gem "http_parser.rb", "~> 0.6.0", :platforms => [:jruby]

Thank you for reporting this, @martgil. However, Minima won't be switching over to the @use API from DartSass in order to maintain compatibility for users still on Jekyll 3.x but using jekyll/minima:master via the jekyll-remote-theme plugin.
To reduce the warnings to a minimum, you may set the quiet_deps sass config in your config file as following:
# _config.yml
sass:
quiet_deps: true
Ideally, silence_deprecation: import or silence_deprecations: [import] should also work, but for some reason, it doesn't. Perhaps @ntkme can provide insight on that.
@ashmaroli PR to add new deprecation options: https://github.com/jekyll/jekyll-sass-converter/pull/164
Please take a look when you get a chance.
Thanks, @ashmaroli, for the detailed explanation, and @ntkme for creating the PR. I understand the reasoning and the decision.
The correct way is to ask users using Jekyll 3 to write gem 'minima', '< xxx' in their Gemfile, where xxx is the first version of minima that migrated to @use.
Minima won't be switching over to the
@useAPI from DartSass in order to maintain compatibility for users still on Jekyll 3.x but usingjekyll/minima:mastervia thejekyll-remote-themeplugin.
If I understand correctly, you are saying that neither the v2.x branch nor the v3.x branch of Minima will be updated to the new DartSass API, right?
Is there any pathway to a later breaking release that is compatible with DartSass v3.x?
@maxkapur Yes, you understood my earlier comment correctly. But I have thought about this situation over these days. We may migrate to Dart Sass API completely given that there are already unreleased breaking changes on the default branch.
