  Description     : The reference implementation of Sass, written in Dart

This is a build-dep of furo.

Hi,

sadly dart isn't packaged in Debian. As a workaround, you can use
node-node-sass.

Cheers,
Yadd

Hi,

rsass can appropriately compile sass files which is convenient for Debian
packaging.

Thanks,

Alex

Yes. There is a multitude of sass implementations, including
node-node-sass, node-grunt-sass, rsass, sassc.

There's also a separate ITP for *another* rust sass implementation in
#1093767. It says, accurately, that neither rust implementation is a
complete implementation of dart-sass, which this aims to package.

I have tested rsass against a codebase here and it fails to implement
map.deep-merge, for example.

Really, we should just aim at having the reference implementation here,
because otherwise we're just doing our users a disservice at providing
incomplete `sass` implementations.

CC'ing Edward, since this package grew directly out during the review of node-material-web: that package needs Dart Sass, which can only be built from source with dart2js from the Dart SDK: hence this ITP.

CC'ing also #998024, since this will unblock that one.

Having dart-sdk finally unblocks the long-standing RFP #998024 (Dart Sass) which could then be packaged and close it (also a prerequisite for #931793, Flutter). The proof of concept already builds the Dart SDK from source, offline, in sbuild with the Debian toolchain (using system clang/gn/ninja) and a self-hosting bootstrap like ghc/gnat;

I'll need some guidance regarding the agreement on that bootstrap before any upload. I would appreciate anyone pitching in on this.

Best,

Juan

Hi,

(Resending once more: two earlier attempts at this text did not reach the
bug log.  Apologies for the noise.)

I am taking this RFP over, so please read it as an ITP from now on.

  Programming Lang: Dart, shipped as JavaScript (built with dart2js)

Dart Sass is the reference implementation of the Sass stylesheet language,
and the only one still maintained: Ruby Sass reached end of life in 2019,
and the LibSass family was declared end-of-life upstream on 2025-10-23
(its repository has had no commit since 2023-12).

Debian currently ships only the retired implementations -- libsass 3.6.5,
sassc 3.6.1, node-node-sass 9.0.0 and python3-libsass 0.23.0 -- and the
"sass" virtual package is provided solely by ruby-sass, whose own short
description reads "deprecated CSS compiler".  Anything using the modern
module system (@use / @forward), sass:math or CSS color spaces cannot be
built with what we have in the archive today.

Naming and packaging, for the record:

- Source and binary package: node-sass, following the JS Team's node-
  prefix convention for the npm module "sass".  (The existing
  node-node-sass is a different package: the npm module "node-sass",
  which is a binding for LibSass.)
- Architecture: all.  The shipped artifact is the dart2js output, so at
  run time it needs only nodejs; dart-sdk is a build dependency.  This
  keeps the package usable where dart-sdk is not available -- dart-sdk is
  currently amd64-only.
- I intend to ship /usr/bin/sass, which collides with ruby-sass (it
  installs /usr/bin/sass, /usr/bin/scss, /usr/bin/sass-convert and three
  man pages), so the package will carry "Conflicts: ruby-sass" together
  with "Replaces: ruby-sass".

Two things I would like the Debian Ruby Team to weigh in on:

1. If you would rather keep both installable, I can put /usr/bin/sass
   under update-alternatives instead of using Conflicts/Replaces.
2. Dart Sass has no equivalent of sass-convert (dropped upstream in Sass
   3.5), and its CLI is a single "sass" binary with no separate "scss"
   command.  Taking over /usr/bin/sass therefore means dropping
   sass-convert, and I need to decide whether to add a small "scss"
   wrapper or let it go.  Please say if anything in the archive relies on
   either of those.

Why now: this bug was blocked by #1140414 (dart-sdk).  That ITP has been
closed and dart-sdk 3.13.4+dfsg1-2 is now in unstable, so I have removed
the block.  I already have a working dart2js build of Dart Sass made with
Debian's own dart-sdk.

I will keep this bug updated, and the first upload will close it.

Regards,
Emfox Zhou

Quoting Emfox Zhou (2026-09-26 14:23:40)

From the project description, it seems that node tool is but a thin
wrapper, so provide that only as binary package name: Upstream project
is *not* mainly oriented towards Node.js.

Please provide the executable binary as dart-sass (or sass-dart), to
allow the user to switch between multiple implementations themselves
Historically sass was one single thing, implemented in Ruby, but
nowadays it is multiple implementations *and* multiple slightly
incompatible specifications, so this is not a decision tied to the Ruby
packaging but generally about the usability of the splintered world of
Sass/SCSS.

In short: Do *NOT* introduce package names or executable names that
conflict with existing packages or tools.

Thanks a lot for packaging dart-sass.

Cool, and interesting.
Note that https://tracker.debian.org/pkg/rsass has recently been added to
Debian,
so the "need" for node-sass is somewhat tamed by rsass.

Follow-up on the naming point raised earlier in this report.

The source package is now dart-sass, matching upstream's project and standalone
executable name, as suggested there.  One source builds two binaries:

  dart-sass   the compiler as a self-contained native executable, installed as
              /usr/bin/dart-sass; Architecture: amd64, and it needs neither the
              Dart SDK nor Node.js at run time
  node-sass   the dart2js build as the Node.js module "sass", installed under
              /usr/share/nodejs/sass for bundlers such as sass-loader;
              Architecture: all

The generic command name is not claimed outright: the package provides the
virtual package "sass" and offers /usr/bin/sass, with its manual page as an
alternatives slave, through update-alternatives (priority 40), which is what
Policy 3.9 asks for so that implementations can be installed together.  No
Conflicts/Replaces and no dpkg-divert are used.  ruby-sass ships that path as a
plain file, so there the name stays with ruby-sass and our alternative is only
registered; ruby-sass is being asked separately to offer it as an alternative
too.

The Debian NEW review of dart-sass 1.105.0-1 has been completed.

Decision: ACCEPTED
Reviewer: Andrew McMillan

Review comment:

Hi,

I have accepted this, but I notice there are a raft of dart packages awaiting review, and I would recommend at least addressing #2 below for other builds.

There are attribution-accuracy problems in debian/copyright:

1. Missing third-party attribution (PostCSS).

pkg/sass-parser/lib/src/stringifier.ts:7-10 explicitly states "Portions of this source file are adapted from the PostCSS codebase," © 2013 Andrey Sitnik (MIT). The Files: * stanza credits only "2016, Google Inc." and has no separate stanza for these PostCSS-derived portions. Still MIT (DFSG-free), but the copyright file fails to acknowledge a real third-party copyright holder.

2. Files: debian/* stanza absent.

The packaging files' own copyright (packager) isn't attributed separately; the lone Files: * stanza technically covers them too but general practice is to include a debian/* stanza recognizing the work of the Debian packagers.


Packaging quality
=================

Build-Depends incomplete relative to pubspec.yaml.

The pubspec declares http and typed_data as dependencies, but dart-http and dart-typed_data are missing from Build-Depends (debian/control:5-34). It currently doesn't break the build only because the compiled entry points (bin/sass.dart, lib/src/js.dart) never import package:http (used only in tool/grind/*) or typed_data. This is fragile and inconsistent; conversely dart-cli-pkg, dart-ffi, dart-fixnum are in Build-Depends though only used by dev tooling, not compiled output.


Thanks!

I think we should just drop any CLI tools from ruby-sass. In the long
term, we should probably remove it entirely, but the reverse
dependencies need to be updated first.

Reverse-Depends
===============
* libplack-middleware-file-sass-perl
* openqa-common
* sass-spec

Reverse-Recommends
==================
* libplack-middleware-file-sass-perl
* nanoc
* ruby-haml [amd64 arm64 armhf i386 loong64 ppc64el riscv64 s390x]
* sass-elisp
* sass-spec

I just uploaded a version of ruby-sass that removes the command line
tools. You could make dart-sass Breaks: and Replaces: ruby-sass (<<
3.7.4-7~)
