Token for matching strings that match a given regular
expression. Defined with string specifying the regular expression in
a form recognized by the stdlib Python `re module <https://docs.python.org/3/library/re.html>`_.
If the given regex contains named groups (defined using ``(?P<name>...)``),
these will be preserved as named parse results.
If instead of the Python stdlib re module you wish to use a different RE module
(such as the `regex` module), you can replace it by either building your
Regex object with a compiled RE that was compiled using regex:
Example::
realnum = Regex(r"[+-]?\d+\.\d*")
date = Regex(r'(?P<year>\d{4})-(?P<month>\d\d?)-(?P<day>\d\d?)')
# ref: https://stackoverflow.com/questions/267399/how-do-you-match-only-valid-roman-numerals-with-a-regular-expression
roman = Regex(r"M{0,4}(CM|CD|D?{0,3})(XC|XL|L?X{0,3})(IX|IV|V?I{0,3})")
# use regex module instead of stdlib re module to construct a Regex using
# a compiled regular expression
import regex
parser = pp.Regex(regex.compile(r'[0-9]'))
