fixed - timestamp problem on changing url in css

[lancejpollard]

I use a sprite plugin that appends the timestamp to the url in css:

url(/images/logo.png?194819891)

So if you just add url = url.split("?")[0], to the following method, it works great!

def replace_css_images!(options={})
  options[:prefix] ||= ''
  # adapted from https://github.com/blakink/asset_id
  data.gsub! /url\((?:"([^"]*)"|'([^']*)'|([^)]*))\)/mi do |match|
    begin
      # $1 is the double quoted string, $2 is single quoted, $3 is no quotes
      uri = ($1 || $2 || $3).to_s.strip
      uri.gsub!(/^\.\.\//, '/')

      # if the uri appears to begin with a protocol then the asset isn't on the local filesystem
      if uri =~ /[a-z]+:\/\//i
        "url(#{uri})"
      else
        url = url.split("?")[0]
        asset = Asset.new(uri)
        # TODO: Check the referenced asset is in the asset_paths
        puts "  - Changing CSS URI #{uri} to #{options[:prefix]}#{asset.fingerprint}" if @@debug
        "url(#{options[:prefix]}#{asset.fingerprint})"
      end
    rescue Errno::ENOENT => e
      puts "  - Warning: #{uri} not found" if @@debug
      "url(#{uri})"
    end
  end
end
