Enables the creation of random expressions based on formulars similar to Perl regular expressions. Additionally, functions can be used to further enhance the application's functionality. Examples: - "[:upper:]{4}-[:number:]{100-900}-[:upper:]{4}" will produce for instance "WUMT- 357-HJLN" - "[:hexu:]{2}(:[:hexu:]{2}){5}": produces a random MAC address (2 uppercase hex characters, followed by 5 occurrences of a colon, followed by 2 uppercase hex characters) - "[:any:]{10,15}": produces a very strong password with 10 to 15 characters, such as e.g. "ršqσë(éæ¼%=" - "scramble(rpad([:upper:]{3,5}[:lower:]{4,8}[.\,;]{1,3},12,:number:))" produces something like "mvzv;7ZXLUIf" (3 - 5 uppercase letters, 4 - 8 lowercase letters, one of (".", ",", ";"), filled up to 12 characters with a number and then put into an arbitrary sequence)
