Sass @import rules are deprecated and will be removed in Dart Sass 3.0.0

[Weishaupt]

Hey @yous,

I've just upgraded my bundle to all latest versions. Now I see some deprecation warnings w.r.t. whiteglass.

Deprecation Warning: Sass @import rules are deprecated and will be removed in Dart Sass 3.0.0.

More info and automated migrator: https://sass-lang.com/d/import

@import "whiteglass";

The first warning is related to the description on how to customize whiteglass

The other warnings are from whiteglass.scss

// Import partials.
@import
  "whiteglass/base",
  "whiteglass/layout",
  "whiteglass/syntax-highlighting"
;

Two further deprecation warnings are related to adjust-color()

Deprecation Warning: Global built-in functions are deprecated and will be removed in Dart Sass 3.0.0.
Use color.adjust instead.

Hi @Weishaupt,

Recently whiteglass v1.11.6 tried to replace lighten and darken with color.adjust, but #54 occurred. In Jekyll < 4, which is used by default github-pages gem (github/pages-gem#813), there is no @use and color.adjust (https://sass-lang.com/documentation/modules/color/#adjust).

The latest sass-embedded is 1.80.5, so I think we can pin sass-embedded to < 3 in 1.11.x releases for Jekyll < 4, and make 1.12.x releases with newer syntaxes for Jekyll >= 4.

Hey @yous,

this sounds like a good idea. Would you create a new branch for 1.12 then to be able to maintain releases for both branches, or just be done with 1.11?

I'm thinking about this:

• 1.x for Jekyll < 4
  • 1.11.x for current state and disable warnings that will be deprecated in Dart Sass 3.0.0
  • 1.12, 1.13, ... for whiteglass' new features
• 2.x for Jekyll >= 4
  • 2.0 when Dart Sass 3.0.0 is released
  • 2.1, 2.2, ... for whiteglass' new features

When Dart Sass 3.0.0 is released, master will bump to 2.0, and I'll make 1.x branch for Jekyll < 4.

jekyll-sass-converter recently added feature that can specify silence_deprecations option, but a new version has not been released.

• Add support to configure more deprecation warnings from Dart Sass jekyll/jekyll-sass-converter#164

You can specify gem 'sass-embedded', '< 1.80' to disable warnings temporarily. When next version of jekyll-sass-converter is released, you can add the following lines to _config.yml:

sass:
  silence_deprecations: [import, global-builtin]
