gluon VS Wren

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.

For a moment I thought it was about wren programming language... [1]

For "W" you could use Wren.

Bob Nystrom also has a blog, and his articles are really well written (see his post on Pratt parsers / garbage collectors). I'd also recommend going through the source code for Wren, it shares a lot of code with Lox. Despite the deceptive simplicity of the implementation, it (like Lox) is incredibly fast - it's a great way to learn how to build production grade compilers in general.

Only kind of unrelated ... Every time I see the Bevy logo I'm reminded of Wren language https://wren.io/

If you want a pure C99 (sadly not C89 like Lua) immensely fast embeddable language pure interpreter, wren is a great language with excellent features like overload by arity. There is a huge maturity gap between the languages tho.

Check out the source to Wren: https://wren.io. It’s from the author of Crafting Interpreters and builds directly on what’s discussed in the book (essentially a more complete Lox) and adds several additional types, including an array.

The best C code I have ever read is that of wren.
