I've seen people claiming - with a straight face - that mechanical refactoring is a good use-case for LLM-based tools. Well, sed was developed in 1974 and - according to Wikipedia - first shipped in UNIX version 7 in 1979. On modern machines it can process files at speeds of several GB/s and will not randomly introduce errors while processing them. It doesn't cost billions, a subscription or internet access. It's there on your machine, fully documented. What are we even talking about?
@gabrielesvelto to be fair I'd much more trust Claude to write the sed regexes than myself... but it's inexcusable to brute force that kind of string replacement work directly with an LLM!
Regex Generator - Creating regex is easy again!

A tool to generate simple regular expressions from sample text. Enable less experienced developers to create regex smoothly.

@RandamuMaki @gabrielesvelto oh, that expression builder in the second step is really nice! wish it would then do match testing on more lines in further steps like how regex101 does
