  • Ruby Sass Has Reached End-Of-Life

    Posted 4 April 2019 by Natalie Weizenbaum

    One year has passed since we announced the deprecation of Ruby Sass, and it has now officially reached its end-of-life. We will release one final version of the Ruby Sass gem that will print a warning indicating that it’s no longer receiving updates, and then archive the GitHub repository.

    We will then merge the sass/language repo into the sass/sass repo. This means that anyone still depending on Ruby Sass from github.com/sass/sass will break. Going forward, the sass/sass repo will be the location for working on the language specs, and will not contain any code. The sass/language repo will just include links pointing to sass/sass.

    Migrating AwayMigrating Away permalink

    If you haven’t migrated away from Ruby Sass yet, now is the time. The best way to do that depends on how you use Ruby Sass today.

    If you use Ruby Sass as a command-line tool, the easiest way to migrate is to install Dart Sass as a command-line tool. It supports a similar interface to Ruby Sass, and…

  • Request For Comments: Module System

    Posted 27 November 2018 by Natalie Weizenbaum

    Many of the most frequently-requested features for Sass have to do with its imports. The import system that we’ve had since the very early releases of Sass is, to put it simply, not great. It does little more than textually include one Sass file in another, which makes it hard to keep track of where mixins, functions, and variables were defined and hard to be sure that any new additions won’t happen to conflict with something elsewhere in the project. To make matters worse, it overlaps with CSS’s built-in @import rule, which forces us to have a bunch of heuristics to decide which is which.

    Because of these problems and others, we’ve wanted to do a full overhaul of the way Sass files relate to one another for a long time. Over the last few years, I’ve been working with the Sass core team and Sass framework maintainers to create a proposal for a module system that’s fit to replace @import. That proposal is now in a place that…

  • Feature Watch: Content Arguments and Color Functions

    Posted 14 November 2018 by Natalie Weizenbaum

    Dart Sass 1.15, released today and available on npm and all other distribution channels, brings with it a number of highly-anticipated new Sass features. This is also the first release of Dart Sass with major new language features that aren’t just for CSS compatibility. That’s a big accomplishment, and we intend to continue that pattern moving forward!

    @content Arguments@content Arguments permalink

    Mixins that take @content blocks can now pass arguments to those blocks. This is written @content(<arguments...>). If a mixin passes arguments to its content block, users of that mixin must accept those arguments by writing @include <name> using (<arguments...>). The argument list for a content block works just like a mixin’s argument list, and the arguments passed to it by @content work just like passing arguments to a mixin.

    // style.scss
@mixin media($types...) {
  @each $type in $types {
    @media #{$type} {
      @content($type);
    }
  }
}

@include media(screen, print) using ($type)...

  • Feature Watch: CSS Imports and CSS Compatibility

    Posted 13 August 2018 by Natalie Weizenbaum

    Dart Sass 1.11 has just been released, and with it a handful of new features. This is an exciting moment, because it marks the first major new feature that’s been added to the language since Dart Sass was launched. It’s also the first release with features that have gone through the new process, from proposal to tests to implementation.

    The biggest feature in Dart Sass 1.11 is support for importing plain CSS files. This is a long-awaited feature, and while we’d initially planned on waiting on it until we launched the upcoming module system, we ended up deciding to implement it earlier.

    You can now import a CSS file, say styles.css, just by writing @import "styles". That file will be parsed as plain CSS, which means that any Sass features like variables or mixins or interpolation will be disallowed. The CSS it defines will become part of your stylesheet, and can be @extended just like any other styles.

    There are…

  • Request For Comments: Importing CSS Files

    Posted 9 July 2018 by Natalie Weizenbaum

    As Dart Sass catches up with Ruby Sass in terms of usability, we’re starting work on adding new features to the language. The first feature we’re looking at is one that’s long been requested by users: adding support for importing plain CSS files without having to rename them to .scss. Not only do we expect this to be very useful, it’s already partially implemented in LibSass, so this will help bring the implementations more in line with one another.

    We’re also trying out a new process with this feature. In order to help keep the behavior of different implementations in sync, we’re starting with a prose specification of the feature before moving on to writing code. We’re also taking this as an opportunity to solicit feedback from you, the Sass community! We want to hear your thoughts on the new feature while we have a chance to revise it based on that feedback.
