Support for quantifiers and the shuffle operator in regular expressions
See original GitHub issueIs there a specific reason why quantifiers for regular expressions are not supported? (so things like a{2,10}
) If there is no specific reason, would you be open to a PR that implements it?
Also, what do you think of adding a special regex shuffle operator? This would be very handy to express languages like “all permutations of a,b,c”. My proposal would be to use the ~
character and implement a separate parser for that

@eliotwrobson Very well! Issue reopened. 🙂
@eliotwrobson pyparsing is a dependency of pandoc, which I used to compile my Markdown README to RST for PyPI (see c669875380fd63f7a69b96b7ae3a02ff0aa6dd8b). I removed pandoc a while back since PyPI now has native Markdown support, but I guess I forgot to remove pyparsing as well.
@EduardoGoulart1 Looking forward to your PR! Please remember to add the appropriate unit tests and documentation (under
docs/regular-expressions.md
) as well.
