LPT: ChatGPT is incredible for generating and evaluating regex (programming.dev)

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.

My biggest problem with it has been that it doesn't necessarily understand that some things are impossible - for example, variable-length lookbehinds.

That depends on the regex flavor. Some of them have full support for variable length lookbehinds, for example JavaScript and third-party regex module for Python.

A variable length lookbehind is the same as the opposite of a variable length lookahead.
