RegexpParser

Generate a regexp that matches any single character allowed in a regexp

This method will generate a regexp that can be used to determine whether a given character could in theory be allowed in a string that matches the source regexp. For example, the source regexp /^a+$/D would generate /a/ while /^foo\d+$/D would generate /[fo\d]/ whereas the regexp /foo/ would generate // because it's not anchored so any characters could be found before or after the literal "foo".

Return the name of each capture in given regexp

Will return an empty string for unnamed captures
