There's Lua implementation [1] in pure Rust, by the way.

The rust ecosystem is doubling down on wasm with little to no focus on lua (some would even prefer to build their own programming language) that doesn’t mean lua is pretty bad for the rust ecosystem it’s just that there’s no much focus as to compared to wasm Example I noticed is https://github.com/kyren/luster

Tossing my hat in for Passerine [1]. Gorgeous ML inspired syntax. Built for scripting Rust applications.

Dreaming here: Lua is a fantastic scripting language, but the Rust FFI isn’t as ergonomic as it could be. Enter Luster [2], which is basically LuaJIT rewritten in Rust.

Embedding a scripting language in a Rust application gives you tons of power (e.g. scripting Rust structs from Lua [3]), and setting this up isn’t terribly difficult.

Some of you may be familiar with MoonSharp LUA interpreter for C#, often use in Unity engine to add scripting support to your game. That's what we took as a base for writing the code for abilities. Each ability can subscribe to different events such as whenever a card takes damage, is placed on the field or ability is used manually on some specific targets. Besides having event handlers we needed a way to specify some metadata like mana cost of abilities, cooldown, icon, etc. and in the first iteration of the system we had a pair of JSON metadata file and LUA code file.

Rather than making your own language, just add Lua to your project. Moonsharp is pretty good with Unity...
