Re: Embedding Ruby within SASS

It would be very useful to add application configuration
settings at
sass=>css compile time. Otherwise you are forced to
replicate your
global settings in your sass instead of simply:

#thing
  width: APP_CONFIG['max_width']

I agree that variables don't make a lot of sense (variable
css should
be done inline) but setting certain values at compile-time
is very
useful to the DRY app.

anyone managed it yet?

Just ran across this trying to figure it out. Since it
sounds like
there's no solution, I brewed one up:

in lib/sass_ext.rb:
module Sass
  module Constant
    APP_CONFIG = YAML.load_file("#/config/
sass_constants.yml")[RAILS_ENV]
    class << self
      def get_constant(value, constants)
        to_return = constants[value] || APP_CONFIG[value]
        raise SyntaxError.new("Undefined constant:
"!#"")
unless to_return
        to_return
      end
    end
  end
end

in config/environment.rb:
require 'sass_ext'

in config/sass_constants.yml:
development:
  host: "localhost:3000"
production:
  host: "example.com"
test:
  host: "localhost:3000"

in a .sass file:
:background-image = "url(http://" + !host +
"/images/foobar.png)"

I needed something like that so our CSS could be linked
remotely and
still work.
