I have to use a ton of regex in my new job (plz save me), and I use ChatGPT for all of it. My job would be 10x harder if it wasn’t for ChatGPT. It provides extremely detailed examples and warns you of situations where the regex may not perform as expected. Seriously, try it out.
Not just for writing, and testing samples. It will also explain the parts of the regex.
However it won’t generate examples that will pass the regex - which may be the biggest benefit of chatGPT.
