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.

Building a baseline JIT for Lua automatically
As far as I can tell, they aren't.
http://lua-users.org/wiki/SandBoxes
There is a lot of information there, but it doesn't handle resource exhaustion, execution time limits or give any guarantees. It does indicate that it's possible, and has a decent example of the most restrictive setup, which is a good start. But I would for example compare it with Luau's SECURITY.md.
From https://github.com/luau-lang/luau/blob/master/SECURITY.md:
> Luau provides a safe sandbox that scripts can not escape from, short of vulnerabilities in custom C functions exposed by the host. This includes the virtual machine and builtin libraries. Notably this currently does not include the work-in-progress native code generation facilities.
> Any source code can not result in memory safety errors or crashes during its compilation or execution. Violations of memory safety are considered vulnerabilities.
> Note that Luau does not provide termination guarantees - some code may exhaust CPU or RAM resources on the system during compilation or execution.
So, even luau will have trouble with untrusted code, but it specifies exactly what happens and so on. I think that's fair enough.

Pluto, a Modern Lua Dialect
Alternatively, Luau is a well-supported Lua variant with type checking and performance improvements, aimed more towards being a sandboxed embedded scripting environment.

Buzz: A lightweight statically typed scripting language
If you need Lua but also type-safety, how about Luau [1] then?

Lua Criticism Is Unwarranted
I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.
I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example
function foo(x: number): string

Ask HN: Looking for platforms, other than Roblox, that have adopted Luau
Looking at other replies here, I can see I wasn't the only one who didn't realize there is Lua and Luau. Luau is an extension of Lua: https://luau-lang.org/
> Luau is syntactically backwards-compatible with Lua 5.1 (code that is valid Lua 5.1 is also valid Luau); however, we have extended the language with a set of syntactical features that make the language more familiar and ergonomic.

Embeddable Common Lisp 23.9.9
Lua is usually the embedded language of choice. If you are focused on security, you could check out the Roblox fork, Luau (https://github.com/Roblox/luau) where the creators took extra care to lock down the language on what scripts could do.

On a side note, I've heard that they recently switched from Lua to Roblox's own fork of Lua, Luau.

Announcing mlua v0.9 (rc) - Full featured Lua bindings to Rust
The release notes can be found here.

Do Rust and Lua work well together?
I'm not a specialist about text based multiplayer game, but from what I saw on Wikipedia it seem doable to do it with Rust and Bevy. On top of that you can add a layer of LUA with https://github.com/khvzak/mlua (or write your own bindings and sandbox later).

Introducing Petrichor64 - a rust and wgpu built game engine/fantasy console with lua game logic
mlua can run on emscripten target with Luau backend -> https://github.com/khvzak/mlua/issues/23
- I was searching for embedded lanaguages in Rust and I found out I can use deno https://deno.land/[email protected]/embedding_deno which is amazing has anyone tried it ?

Repos using rlua/mlua
You can also look at the "dependents" section on crates.io https://crates.io/crates/mlua/reverse_dependencies and github https://github.com/khvzak/mlua/network/dependents

is rlua-async supports mutli-threading?
I know mlua does support Async. I also prefer it over rlua
-
Rust and Lua api
Note rlua doesn't allow you to create native modules with it and has largely been superseded by https://github.com/khvzak/mlua since it's more maintained, has native module support and stuff like Luau and async/await.

Lua: Good, Bad, and Ugly Parts
I believe mlua [0] is the recommended Lua Rust binding now.
-
Dash.nvim v0.8.0 now supports Telescope, fzf-lua, and Snap fuzzy finders!
This is achieved through a backend/client architecture -- all core functionality (getting query results, opening selected item, search engine fallback, etc.) is implemented in a "backend" module, which is a Rust library exposed as a Lua module via mlua. The results returned by the backend then get fed into your fuzzy-finder of choice through thin clients, or "providers".
