re,err := regexp.Complie(match)

    return err

What did you see happen?

report errors: error parsing regexp: invalid or unsupported Perl syntax: (?!

What did you expect to see?

I hope the pro version can solve this problem

closing as working as intended.

See https://swtch.com/~rsc/regexp/regexp1.html for why Go regular expressions do not support ?!.

By the way, there is no pro version.

You can use this, but it doesn't have an ideal version. Regux has been updated and the previous one is even more unusable. I found that version 22 can still be used, but there are still parsing issues,
