So I was trying to write a regex for use with my ChatGPT discord bot. I wanted to trim off any final partial sentence at the end. I went around and around with it for a couple of hours because look ahead and look behind are just not something I do often enough.
It kept writing more and more complicated regex that didn’t work. The final solution, while not exactly perfect - it won’t keep a quote at the end of a sentence, and honorifics like Mr. and Dr. throw it - it wasn’t nearly as complicated as ChatGPT was making it. It still never did give me anything working - I just fucked around on regex101 until I got it right. As usual but having wasted 90 minutes or so.
I've found that you need to be very careful when asking it to modify things it produced directly without making significant changes to the regex it provides. Once I get to the 3rd or 4th iteration of asking it to modify previous responses I've found the likelihood that it starts hallucinating to increase dramatically. The best solution I've found to this is to put your entire request in a single prompt that walks it through all requirements step-by-step.
