Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What config format do you prefer?
I haven't seen anyone mention starlark yet. It's something I want to play with as a config language.
-
loxcraft: a compiler, language server, and online playground for the Lox programming language
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.

Launch HN: Moonrepo (YC W23) – Open-source build system
There is also a Rust implementation of Starlark as a starting point https://github.com/facebookexperimental/starlark-rust
To add to everyone else, please don't use YAML. Starlark is great _precisely_ because it is a readable, well known (nearly Python) language that is limited at the same time (no unbounded for loops, no way to do non-deterministic things like get the current time or `random()`).

Benchmarking Starlark against other embedded scripting languages
This is a follow-up to Benchmarking mlua/rlua/rhai - Rust embedded scripting languages from 4mo ago; I just added the new Starlark implementation from Meta to the benchmark posted by @aleksru.

The Perfect Configuration Format? Try TypeScript
The Rust implementation has it as an experimental extension (https://github.com/facebookexperimental/starlark-rust/blob/m...)

Making an interpreter for variable length byte-code, any way to use enums for this and not just a big u8?
u/ndmitchell has been working on a Starlark interpreter. He wrote up a blog post with some thoughts about different interpreter styles. He found that in his case using fixed sized instructions was about the same as byte-encoded ones, but compiling the AST to closures was also about the same performance as well, and doesn't need an AST->bytecode compiler.
-
Can i use rust to write my compiler??
As mentioned in other comments, type system features like algebraic data types (that Rust has) are really helpful. If you want a small-but-real example of a compiler in Rust (with an optimizer etc) then the starlark-rust compiler is good.

Zellij – A Terminal Workspace and Multiplexer Written in Rust
If your Rust program needs a more complicated configuration (conditionals, access to APIs and so on), also look at Facebook's Starlark parser and tooling[1]. Starlark is a subset of Python used by Bazel, Buck and a few other projects.

New version of Rust Starlark, an implementation of a deterministic Python-like language
The Facebook post gives a nice overview. It also links out to the home page for the project at https://github.com/facebookexperimental/starlark-rust/, which has an introduction and links to what Starlark is, the crates.io link, the docs.rs link etc.

Embeddable Scripting Language for Embedded Rust
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.

Modules and Imports
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:
- Gluon: A New Node.js Framework to Create Desktop Apps
- Rock v0.2.1, a little native toy language I've made with Rust and LLVM.
- Gluon: A static, type inferred and embeddable language written in Rust

Fornjot – The world needs another CAD program
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.

Dynamic language extensions for Rust?
Or if you wanted something more Rust-native, you could try Gluon.
