The regexp example on https://sourcegraph.com/cody has been broken for months (scroll down a bit, second block). Also not a regexp problem and easier solved without regexps.
Please, no one tell them. It's funnier the longer it goes on. It's been like this since at least October (I told a friend on Telegram this), but it had already been like this for some months by then.
Explain this regex: [a-zA-Z0-9\.\-]+\.([a-zA-Z]{r,63})
And part of the explanation was to fix the bug. Well, almost, it removed the () in the process, but it did know what was wrong.
