A function to resolve sass dependencies. Might come in handy with the grunt sass plugin. This is from guard-sass reference to: https://github.com/hawx/guard-sass/pull/31

resolve_sass_dependencies.rb

def resolve_partials_to_owners(paths)
	# Get all files that might have imports
	root = (options[:input][-1] == "/" ? options[:input] : "#{options[:input]}/").reverse
	search_files = Dir.glob("#{options[:input]}/**/*.s[ac]ss")
	search_files = Watcher.match_files(self, search_files)

	# Get owners
	owners = search_files.select do |file|
		# Get dependencies of file
		deps = Sass::Engine.for_file(file, {}).dependencies.collect! {|dep| dep.options[:filename]}
		# Find intersection with paths
		deps_in_paths = deps.intersection paths
		# Any paths in the dependencies?
		!deps_in_paths.empty?
	end

	# Return our resolved set of paths to recompile
	paths + owners
end
