see that's fine with me if they want to take a year or two of human time and do the rewrite properly
replythis is a piece of software with no architecture, and whose owners have no regard or respect for architecture. I can virtually guarantee that on average every bug they fix will create one new bug, because that's what it's like to work on software with no intentional architecture
What are you talking about?? Bun in Rust is a port, almost exactly the same code base on a different syntax. The architecture did not change at all. Amazing how people comment without even knowing what they are talking about.
replyZig and Rust are significantly different languages. If bun has a good architecture in zig (which I don't know if it does or not), that doesn't necessarily mean it had a good architecture for rust. A direct translation of zig code would probably result in pretty unusual rust code, and probably a lot more unsafe usage than if it had been originally written in rust.
replyI don’t really understand this objection. For every tool that I use, am I supposed to divine the best underlying language for it and then determine whether or not it is written in that language? Don’t I have better things to do?
replyVery amazing indeed. Here you are making bold assumptions about a huge pile of code not a single human being has ever read in any meaningful amount.
replyThe only assumption you need to make is how the process went about, which was described by Jarred on a HN comment when the PR was first discussed: they had prompt that described exactly how things should be translated, for each "pattern" they were using in Zig, an appropriate equivalent was described in Rust. Zig and Rust are not that different, both are system languages and things can be done similarly in both languages, so architecture-wise I would think the exact same thing would work fine. I am not sure whether the LLM actually wrote a transpiler which just followed the rules, or if it did the job itself, since that information is not public yet, as far as I know, but my guess is that the LLM wrote a transpiler to do the job, then reviewed/fixed compilation issues, then fixed tests. And I'm pretty sure some human interaction was part of that as well.
