Bjørn Erik Pedersen 41a080b268 tocss: Add vars option ... This commit adds a new `vars` option to both the Sass transpilers (Dart Sass and Libsass). This means that you can pass a map with key/value pairs to the transpiler: ```handlebars {{ $vars := dict "$color1" "blue" "$color2" "green" "$font_size" "24px" }} {{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }} {{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }} ``` And the the variables will be available in the `hugo:vars` namespace. Example usage for Dart Sass: ```scss @use "hugo:vars" as v; p { color: v.$color1; font-size: v.$font_size; } ``` Note that Libsass does not support the `use` keyword, so you need to `import` them as global variables: ```scss @import "hugo:vars"; p { color: $color1; font-size: $font_size; } ``` Hugo will: * Add a missing leading `$` for the variable names if needed. * Wrap the values in `unquote('VALUE')` (Sass built-in) to get proper handling of identifiers vs other strings. This means that you can pull variables directly from e.g. the site config: ```toml [params] [params.sassvars] color1 = "blue" color2 = "green" font_size = "24px" image = "images/hero.jpg" ``` ```handlebars {{ $vars := site.Params.sassvars}} {{ $cssOpts := (dict "transpiler" "dartsass" "outputStyle" "compressed" "vars" $vars ) }} {{ $r := resources.Get "scss/main.scss" | toCSS $cssOpts }} ``` Fixes #10555		2022-12-20 19:36:30 +01:00
