LPT: ChatGPT is incredible for generating and evaluating regex

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.

Just make sure to test the regex instead of blindly slapping it in assuming it works 🙂

What if I say "it's probably okay just this one time" before I do it every time?

Ah I've tested this method, shit breaks a lot. Still my go to.

Can we just have another LLM check the work for us? Like an LLM-GAN?

I'm not sure if it's still the case, but asking it to review what it just wrote for errors has led to significant quality improvements previously.

The new Code Interpreter plugin that went live for this week for Plus users can actually execute Python code on a sandboxed environment. This allows you to add "Write and execute tests for the regex" to the end of your prompt.

Regex101 is a sandbox env specifically for Regex

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.

This is where I go to validate the work of ChatGPT. The debugging capabilities in that site are wonderful.
