^.?$|^(..+?)\1+$ <answer> Matches strings of any character repeated a non-prime number of times https://www.youtube.com/watch?v=5vbk0TwkokM
minus-square@[email protected]linkfedilink5•2 months agoYes, the first one matches only 2 more characters while the second matches 1 or more. Also the +? is a lazy quantifier so it will consume as little as possible.
minus-square@FeathercrownlinkEnglish3•2 months agoI was like, why specify “one or more” and then make it optional? Isn’t that just .*?
Is there a reason to use
(..+?)instead of(.+)?Yes, the first one matches only 2 more characters while the second matches 1 or more. Also the +? is a lazy quantifier so it will consume as little as possible.
Ah, didn’t know +? was lazy, thanks
I thought, the +? was going to be a syntax error. 🙃
