gluon VS mun

A colleague of mine used https://github.com/gluon-lang/gluon with great success in our rust projects. Although it probably can't run in a no_std environment.

Aside from these, if you want some inspiration for a production-grade language built in Rust, you might want to go through the source code of Starlark and Gluon.

Some languages, like Zig and Gluon have an import expression, where the imported symbols are under a local constant's name. Gluon then also supports destructuring, and Zig has had multiple proposals for years about it, none of which are canon. That is, code like this:

This should be a good use-case for rust-based scripting languages, I think.

I loosely followed a project of that kind a while ago, I don't quite remember if it was Gluon [0] or Dyon [1]. Not sure if these are still active, or if another competitor showed up in meantime.

Or if you wanted something more Rust-native, you could try Gluon.

Mun is a statically typed language that compiles to machine code with LLVM, designed to be hot-reloadable: https://mun-lang.org/.

Perhaps https://mun-lang.org? Might be a bit raw for your needs tho.

But that’s not all! In total, this release contains 111 pull requests made by 5 of our community contributors and our two Core Team members & Dependabot. Thanks for having our back! For a full list have a look at the changelog, but the main improvements are:

Whenever I read about Mun, I'm always really, really intrigued… Until I remember that it currently has no string type and support for one is not currently planned. That's a bit of a shame, IMHO, because otherwise, this looks great!

There's mun [1] which is statically typed and AOT compiled.

From the reverse-dependencies of the salsa crate, the (archived) Lark compiler used it and the Mun compiler uses it.

I notice that there are projects like mun trying to achieve a similar goal, but I'm kind of curious why they are not getting much attention from the community.

Have you heard of https://mun-lang.org/ ?

It's an embeddable scripting language with the goal of being a Rust-like language that supports hot reloading of functions AND data. To achieve the latter, it uses GC'ed memory such that memory can easily be mapped when the memory's type changes.

It's still in early development but maybe one day will serve your needs :)

In terms of pure Rust engines/frameworks it seems the overall "problem" is lack of scripting, at least from my perspective. Mun seemed extremely interesting, but since even the project itself says "don't use it" I guess it's not a real option, and considering the amount of time we spent on the GDScript/Rust integration I'm a little worried that rolling something more custom would be even less efficient.
