I've been working on a Rust-like programming language written in Rust. I've worked on this compiler for the past months, and it's coming along very well.
The language features closures, higher-order function support, recursion, among other interesting things.
Here's the GitHub link, take a look!: https://github.com/geckolang/gecko
Also, come hang out on the official Discord server, I'm very interested on the compiler-design topic and can help you out if you have any questions about the project or designing your own compiler!
