This class converts CSS documents into Sass templates. It works by parsing the CSS document into a {Sass::Tree} structure, and then applying various transformations to the structure to produce more concise and idiomatic Sass.
Example usage:
Sass::CSS.new("p { color: blue }").render #=> "p\n color: blue"
@param template [String] The CSS code @option options :old [Boolean] (false)
Whether or not to output old property syntax (`:color blue` as opposed to `color: blue`).
# File lib/sass/css.rb, line 67 67: def initialize(template, options = {}) 68: if template.is_a? IO 69: template = template.read 70: end 71: 72: @options = options.dup 73: # Backwards compatibility 74: @options[:old] = true if @options[:alternate] == false 75: @template = StringScanner.new(template) 76: end
Converts the CSS template into Sass code.
@return [String] The resulting Sass code
