This is no longer the repository for Embedded Dart Sass. The embedded compiler has been merged into the primary Dart Sass repository, and further releases will be included as part of Dart Sass itself. The embedded compiler can be accessed by running sass --embedded .
brew install sass/sass/dart-sass-embedded seems to no longer install a binary to PATH, and I now see this error when running Hugo:
❯ hugo server -D

Error: error building site: TOCSS-DART: failed to transform "css/paige/bootstrap/370ad5bdcb602baa80412d8e9cd6e25f3b158a68-paige.scss" (text/x-scss). You need dart-sass-embedded in your system $PATH.: this feature is not available in your current Hugo version, see https://goo.gl/YMrWcn for more information
There’s a long story here (with a conclusion coming shortly) which someone else may tell, but I get pretty annoyed reading the above about them retiring the old brew when they well knew that it would take the upstream libraries (e.g. Hugo) to upgrade their Dart Sass integration. I will open an issue somewhere and shout.
To answer the initial Q. If @jmooring is giving me the thumbs up re. the Snap situation, I’m releasing Hugo 0.114.0 tomorrow, which supports both old and new Dart Sass.
