Evaluate SCSS (SASS) templates in ruby (Rails project)

Question

I am working on a sort of CMS project where I am leveraging SCSS. I would like to allow the user to specify properties of a stylesheet in a simple way (enable a few color customization), and then generate a CSS file based on SCSS templates, and substitute some variables in the SCSS file using mustache or ERB evaluation.

Basically, I want an ERB file to be rendered as scss file, and then generate a css in my application, upload it to S3, and include in the user's layout. If possible I would like to avoid using css.erb files :-)

Answer 1

I fact (I am answering my own question). What I am trying to do is really easy. I've made this really simple script:

#!/usr/bin/env ruby

#processs.rb file

require 'sass'
result = Sass.compile open(ARGV[0]).read
puts result

And it generates css out of a scss file she invoked like this:

ruby process.rb myfile.css.scss

And this works perfectly. The code documentation in sass source code helped me to find this out.
