The shortest ooc quine
👋 This page was last updated ~13 years ago. Just so you know.
A few days ago I posted an ooc quine. But while browing HackerNews, I found an even shorter one. The shortest!
Here it is, in its full glory
Can’t see anything? That’s an empty file. It will compile and run just fine. ooc doesn’t require a main function - you can just shove code in there that will run at the program’s initialization. If there’s none, no big deal! It’ll just not run anything.
That’s one nice side-effect of simple design.
Did you know I also make videos? Check them out on YouTube!
Here's another article just for you:
Rust modules vs files
A while back, I asked on Twitter what people found confusing in Rust, and one of the top topics was “how the module system maps to files”.
I remember struggling with that a lot when I first started Rust, so I’ll try to explain it in a way that makes sense to me.
Important note
All that follows is written for Rust 2021 edition. I have no interest in learning (or teaching) the ins and outs of the previous version, especially because it was a lot more confusing to me.
