I am trying to compile my Sass on the Cloud9 (http://c9.io) IDE. I have a Compass config.rb file, which I'd like to be adhered to.
The output of sass -h within the terminal states that a --compass option exists:
mikemike@x:~/workspace/resources/assets/sass (master) $ sass -h compass
Usage: sass [options] [INPUT] [OUTPUT]
Description:
Converts SCSS or Sass files to CSS.
Common Options:
-I, --load-path PATH Specify a Sass import path.
-r, --require LIB Require a Ruby library before running Sass.
--compass Make Compass imports available and load project configuration.
-t, --style NAME Output style. Can be nested (default), compact, compressed, or expanded.
-?, -h, --help Show this help message.
-v, --version Print the Sass version.
I'm unsure how to get this working. There is no additional information on it and simply running sass --compass or sass --compass config.rb just seems to put sass in interactive mode.
The command you just ran is giving you a hint as to how you're supposed to use it. It expects an input and an output. Since you're providing neither, it goes into interactive mode.
You can't specify the location of the config.rb, this is by design. Use the compass command instead (eg. compass watch).
sass --compassis intended to be a quick-and-dirty way to get access to the Compass libraries that don't require any configuration. If you want anything more complicated, you should use thecompassexecutable.
