I used a local model today to write a long form regex for me today. it would have taken me 30 minutes. instead it took 3 seconds and worked out of the box.
I think this is a perfect example of what LLMs should be used for.
Ok. But did you understand the regex? That's what people are missing out on. The learning aspect.
absolutely. I know regex, better than most devs I know personally.
I also don't use it all the time. I happened to have it up and just said, "hey fucker, give me the pcre regex to find all instances of these keywords in a string like this"
reviewed it, threw what I had into my code, ran my tests and everything was golden.
