I am delighted to announce Remacs, a project to port Emacs to Rust!
Emacs, at its heart, is a lisp interpreter written in C. In Remacs, we're replacing this C code with Rust, and all the elisp you know and love will just work.
If you've ever fancied contributing to core Emacs, this is a great opportunity to learn the internals. There's tons of low hanging fruit, we have a list of good first bugs and even a walkthrough of writing your first elisp function using Rust.
Rust is perfect for this because we can port incrementally. If you want to replace the entire regular expression engine, you can do that. If you just want to replace this function here, you can do that and the C code won't even notice. You will have a full-blown Emacs every step of the way.
[...] Remacs is based on Emacs 25.2. We've got enough type definitions that you can write interesting built-in functions, but the project is still at a very early stage. Using these, we've got a few built-in elisp functions written entirely in Rust: some arithmetic, some type checks, and even some basic list functionality.
I'll stick to MrPlow for now, thanks. He's Rust enough for me until his code stops looking like a noob wrote it.
