Take a string representing a regular expression and return the root node of its parse tree. usage:: root_node = parse_regex('(hello|world)') Remarks: - The regex parser processes multiline, it ignores all whitespace and supports multiple named groups with the same name and #-style comments. Limitations: - Lookahead is not supported. )unicode_literalsN)RepeatVariableRegex Lookaheadtokenize_regex parse_regexc$\rSrSrSrSrSrSrg)NodezH Base class for all the grammar nodes.
