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.

Learning on Roblox
Once they grasp some lua basics and I've actually got a little code running but before I do much to make a game. I'd suggest you give them loom my fork includes the documentation with the code. Also a class system either a basic but easy to understand or more featureful.

Could someone critique my way of doing simple OOP and perhaps offer improvements or tell me if I'm doing something wrong?
I can't criticism your implementation at the moment but I want to share a tiny class module for Lua as a inspiration. https://github.com/rxi/classic

New to Lua and coding in general. Trying to understand the self command. Why does Version 1 of this code work and Version 2/3 not work?
(this example uses classic, which is a library I like using for OOP to keep things simple)
-
Arbitrary 'require' order
I like classic over middleclass: https://github.com/rxi/classic Feels lighter weight, like barely anything.
- How would I go about creating a item/object and be able to instance it.
- I'm confused how inheritance works in Lua. What am I doing wrong?

Comparing Unreal, Unity, Godot, and Defold game engines in a graphical table of features
You can do oop in Lua too! You just need a class lib.

I would like to animate a circle moving around a circle (api = love)
I'd recommend spending a bit of time with the readme for classic: https://github.com/rxi/classic

Any Lua exercises?
Get as simple as possible OOP library, for example this one and write some code using it. This library can inherit ordinary functions, but not any metamethods. Try to improve it. If you can implement metamethod chaining inheritance that allows you to __call an instance of inherited classes like a function, then you understand metamethods thoroughly. Even if you fail, it still will be a good practice.

What would be the significant benefits if one would develop equivalent libraries that are available for Python for Lua/Nelua?
Lua is a small language and its "standard library" is very minimal. Lua's intended for embedding so usually the host program provides a broader standard library by exposing functions to lua. However, there are several standard library packages for lua: batteries and lume are focused on gamedev; Penlight aims at bringing the breadth of python's stdlib to lua; plenary.nvim for nvim plugins; and probably more for other domains. I'd definitely recommend checking these out to help get closer to functionality level of most other languages (I use both lume and batteries, but dropped penlight awhile back because I found some implementations confusing/overcomplicated/inconsistent).

The first release of DeathVim
Making a lua-based distro might benefit from packing in an existing lua utility library instead of starting your own: lume (useful single file of utilities) or batteries (organized into modules).

Thoughts on LUA?
Second, hot reload actually works and is usually instant. (lume has one you can adapt, I use gabe's class system and reload since it's already integrated). Since an instance of an object is a table, and functions on the object are elements in a table, you can swap out functions for their new values and keep your current state. By comparison, Unity's C# hot code reloading requires you to serialize your state because it needs to unload the AppDomain. It needs to rebuild the world with the new types. Most serialization occurs automatically, but often it doesn't and you need to add special callbacks to make it work. Regardless, for projects of any real size, it's slow. Not sure how Unreal's Live++ (Live Coding) works, but seems like you can't edit .h files.
-
Idiomatic way to differentiate an ordered table from an unordered one?
From lume:
-
JS-object-like functions for lua tables
Or check out Lume.
-
Lua Table Serializatio
Yeah, lume is not a tiny library, but you can simply take only the functions you need from it. It's source code is very easy to read and (de)serialization implemented there in pretty minimalistic way.
-
Spreading tables in Lua
I'm not very familiar with javascript and its spreading operator, but it seems to me that something similar is in lume. Check out lume.extend and lume.merge.
