MOROS include a simplified regular expression engine with the following syntax:
\ escape the following character to its literal meaning^ matches the starting position within the string$ matches the ending position within the string* matches the preceding element zero or more times+ matches the preceding element one or more times? matches the preceding element zero or one time. matches any single character\w matches any alphanumeric character\W matches any non-alphanumeric character\d matches any numeric character\D matches any non-numeric character\w matches any whitespace character\W matches any whitespace characterThe engine is UTF-8 aware, so for example the unicode character é will be
matched by \w even if it's not present in the ASCII table and has a size
of two bytes.
