Rhai VS lokke

The OS would be built in Rust and the module system could be made using ELF executibles (fast, but it could be really hard to implement modules to communicate with the kernel), WASM (can compile from many languages, slower but not too slow, APIs can be simple enough to implement if the correct VM is choses) or even a custom scripting language like rhai (slower, but best way for the implementation [way to connect modules and kernel]).

For sure, that's where something like rhai would shine: https://crates.io/crates/rhai

Oh yeah, for sure. But there are rust based scripting languages that are designed to interop with rust, such as rhai: https://crates.io/crates/rhai

Markdown support Markdown as a templating language is supported, and you can use global and local configs. Also, there are several built-in helpers, and you can make your own, in the language rhai

I came across this library lately which might be close to what you’re looking for: https://github.com/rhaiscript/rhai

I'm very interested in guile-emacs, not because I think it'll replace main emacs, but I do think it'd be really neat to have my config in a 'cleaner' lisp like scheme, a clojure like language, lokke[0], or even python[1]

There is even a Clojure dialect, although I don't know how mature it is. https://github.com/lokke-org/lokke

I find the choice of name interesting since none of the contributors seem to be Danish. Well, they could of course be Danish and have English names (like me), but I don't think so ;-)
