This is a perfect use case for LLMs at the moment. I wrote a script to update and express code base to hono. I got Claude to write a regex that would match the handler to the route and called the Claude 3.5 api with an example conversion and some other relevant context.

With the right prompt, it produced extremely clean and workable code.

~20 controller files and over 100 route handlers were converted in about 20 minutes and 5 dollars.

I work with code base of >750K LOC C++ that is 12+ years old and would like to migrate it to something fashionable like Futhark or Python. So, please, tell me more about your wonderful regular expression.

I’m not sure why you would want to migrate a C++ codebase to an interpreted language?

[thesz]

I want to migrate from C++ because these languages are fashionable and hip and have more developers available and because migration with regular expressions is easy, apparently.

Actually, a colleague of mine asked me why people keep using bash for scripting instead of Python despite Python being obviously better in all regards. So I decided to joke around about this.
