Missing Rules

• active_url
  • This cannot be supported because JS does not support hostname lookups (dns_get_record in PHP)
  • This could be implemented if there was a reliable way to host a small API to do the lookup
• date_format
  • This can be added with something like return new Date(value).format(params[0]) === value;
• dimensions
  • This requires named params which could be pair = params[i].split('='); namedParams = { [pair[0]]: pair[1] }
• mimetypes
• mime
• not_regex
• regex
  • Regex requires extra parsing to remove forward slashes around regex
