With the release of [Dart Sass 1.0.0 stable](/blog/dart-sass-100-is-released)
|
|
last week, Ruby Sass was officially deprecated. I'll continue to maintain it
|
|
over the next year, but when 26 March 2019 rolls around it will reach its
|
|
official end-of-life. I encourage all users to start migrating away sooner
|
|
rather than later.
|
|
|
|
### The Deprecation Period
|
|
|
|
Over the next year, I'll continue to work on Ruby Sass in a limited capacity.
|
|
I'll triage and fix any bugs that are reported, unless they're minor or obscure
|
|
enough to be unlikely to pose a practical problem over the next year. I'll also
|
|
add support for any new CSS features that require changes to the Sass parser or
|
|
other parts of the language.
|
|
|
|
I won't be working on language features that aren't necessary for CSS support,
|
|
though. The latest and greatest features will be appearing exclusively in [Dart
|
|
Sass](/dart-sass) and [LibSass](/libsass) from here on out.
|
|
|
|
I also won't be accepting pull requests for new Ruby Sass features. While pull
|
|
requests are a great way to contribute to projects, they still take work on my
|
|
part to merge in, and it just doesn't make sense to spend time on that work when
|
|
the project is being turned down. If you're interested in contributing to Sass,
|
|
I highly recommend [contributing to Dart
|
|
Sass](https://github.com/sass/dart-sass/issues?q=is%3Aissue+is%3Aopen+label%3A%22help+wanted%22)—Dart
|
|
is an extremely easy language to learn!
|
|
|
|
We're also be migrating the Ruby Sass repository to
|
|
https://github.com/sass/ruby-sass, so be sure to update your Git URLs. The old
|
|
repository URL will continue to work during the deprecation period, but it will
|
|
be frozen; all ongoing maintenance will happen at the new URL. Once the
|
|
deprecation period is over, the Git history for the old URL will be wiped and
|
|
replaced with feature specifications. See [this
|
|
issue](https://github.com/sass/sass/issues/2480) for the full plan.
|
|
|
|
### Migrating Away
|
|
|
|
We want to make it as easy as possible to migrate from Ruby Sass onto an
|
|
actively-maintained implementation. 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](/install) as a command-line tool. It supports a similar
|
|
interface to Ruby Sass, although it currently doesn't support the `--watch` or
|
|
`--update` flags—[adding them](https://github.com/sass/dart-sass/issues/264) is
|
|
high priority, though!
|
|
|
|
If you use Ruby Sass as a plugin for a Ruby web app, particularly if you define
|
|
your own Sass functions in Ruby, the
|
|
[`sassc`](https://github.com/sass/sassc-ruby) gem provides access to
|
|
[LibSass](/libsass) from Ruby with a very similar API to Ruby Sass. In most
|
|
cases, you can just replace the `Sass` module with the `SassC` module and your
|
|
code will continue to work.
|
|
|
|
If you're using Rails, I particularly recommend using the
|
|
[`sassc-rails`](https://github.com/sass/sassc-rails) gem, which wraps up the
|
|
`sassc` gem and integrates it smoothly into the asset pipeline. Most of the time
|
|
you won't even need to change any of your code.
|
|
|
|
We're also planning to add support to Dart Sass for [embedding it in
|
|
Ruby](https://github.com/sass/dart-sass/issues/248) (and other programming
|
|
languages). This will allow Ruby users to get the latest and greatest features
|
|
as soon as they're implemented.
|
|
|
|
### End of Life
|
|
|
|
On 26 March 2019, the deprecation period for Ruby Sass will end and it will no
|
|
longer be maintained. The new `sass/ruby-sass` repository will be
|
|
[archived](https://help.github.com/articles/about-archiving-repositories/),
|
|
which means no changes will be made and no new issues or pull requests will be
|
|
accepted. The old `sass/sass` repository will have its Git history replaced with
|
|
feature specifications that have historically just been scattered around issue
|
|
comments.
|
|
|
|
Leading up to the end of life, we'll be migrating the user-focused [reference
|
|
documentation](/documentation/file.SASS_REFERENCE.html) from the Ruby Sass
|
|
repository to the Sass website. We could use some help doing the migration and
|
|
touching up the documentation, so if you're interested please [chime in on the
|
|
tracking issue](https://github.com/sass/sass-site/issues/205)!
|
|
|
|
#### Unless...
|
|
|
|
We're turning down support for Ruby Sass because the Sass team just doesn't have
|
|
the bandwidth to maintain it along with the other major implementations. But
|
|
there could be another solution. If someone from the community is willing to
|
|
step up and take on the mantle of maintainer, we'd be more than happy to show
|
|
them the ropes and help them keep Ruby Sass going.
|
|
|
|
Maintaining a language implementation isn't necessarily easy. It requires
|
|
keeping up with features as they're added to Dart Sass, as well as fixing bugs
|
|
and fielding pull requests. But it's also a great opportunity to work on a big
|
|
project with a lot of impact, and I'm happy to help get a new maintainer up to
|
|
speed. If you're interested, please email [me](mailto:nex342@gmail.com) and
|
|
[Chris](mailto:chris@eppsteins.net) and we'll talk about how to get started.
