It replaces the sass-rails gem with the sassc-rails gem for faster compilation.
No, the diff is straightforward.
It was requested in issue #18432 (closed), and generally faster compilation is a good thing :)
master (if it does - rebase it please)Closes #18432 (closed)
Without attempting to be very scientific here are some numbers I got:
Using sassc-rails:
[1] pry(main)> Benchmark.bm { |bm| bm.report { Rails.application.assets["application.css"] } }
user system total real
1.430000 0.380000 1.810000 ( 1.830753)Using sass-rails:
[1] pry(main)> Benchmark.bm { |bm| bm.report { Rails.application.assets["application.css"] } }
user system total real
12.320000 0.530000 12.850000 ( 12.909684)The result is faster page loads when changing CSS in development and faster precompilation.
