css – 使用Compass / Sass删除附加到sprite文件名的随机字符串

asset_cache_buster :none

# Make a copy of sprites with a name that has no uniqueness of the hash.
on_sprite_saved do |filename|
  if File.exists?(fileName)
    FileUtils.mv filename,filename.gsub(%r{-s[a-z0-9]{10}\.png$},'.png')
  end
end

# replace in stylesheets generated references to sprites
# by their counterparts without the hash uniqueness.
on_stylesheet_saved do |filename|
  if File.exists?(fileName)
    css = File.read filename
    File.open(filename,'w+') do |f|
      f << css.gsub(%r{-s([a-z0-9]{10})\.png},'.png?v\1')
    end
  end
end
