asset_url helpers don't work

[ssalzberg]

In switching over from sass-rails to dartsass-rails, I noticed the asset path helpers no longer work. In development mode, something like this works fine:

div {
    background-image: url("path/in/assets/to/image.jpg");
}

but in production, neither that nor this works:

div {
    background-image: asset-url("path/in/assets/to/image.jpg");
}

dartsass-rails cannot pass ruby functions to the dart sass compiler, so that it does not support asset helpers.

If you need the asset-url helper, you can try sassc-embedded and configure your rails app as if it is using sassc. It is based on dart-sass-embedded and provides a ruby API that is compatible with SassC so that sprockets would work as is.

Latest Sprockets and Propshaft will both replace url() to an digest-stamped version.
