cannot load such file -- sprockets/sass_template about sassc-rails

[schneems]

Ahh, it looks like those things got taken out in sprockets 4.x here's the 3.x branch https://github.com/rails/sprockets/blob/3.x/lib/sprockets/sass_template.rb

Any ideas on backwards compatibility changes for sprockets 4? I kinda fell into this maintainer role, there's lots of catching up to do. I think instead of using SassTemplate we can directly use SassProcessor

That sounds like a reasonable place to start, although for now I'd like to at least maintain support for sprockets 2 / 3 as well.

As far as future compatibility goes, there was a push to get LibSass integrated into sprockets and the default sass-rails (rails/sass-rails#349). This will be a lot easier for me to finish once we get to upgrading our project to Rails 5 / sprockets 4.

I'm working to add deprecations for all of these code points in sprockets 3 right now. I've got some ideas on a patch that would work for this to work with sprockets 2, 3 & 4 (all of which are currently supported via me currently).

[schneems]

What I think I would like to do for Sprockets 4 is to fix the built in ScsscProcessor and support sassc natively inside of the sass-rails gem, we probably want to encourage people to use sassc over ruby sass due to speed improvements. I see you've contributed to the processors a bit, if you have some time to take a look at the failure rails/sprockets#323 (comment) I would appreciate it. It's very slow going for me since it's an area of the code i've never touched before.
