Why can I not match against "\w*" for instance? It just says "infinite" and does not seem to attempt to match.
Creator here - this is because \w* matches 0 characters, and thus matches infinitely. You can roll over the "infinite" error for details, or look in the help.
Try \w+ instead.
But \w* matches "" and "abc" but not "!a". How can I test this with your tool if \w* always says "infinite"?
