Penlight
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 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.

Pluto, a Modern Lua Dialect
To have enough batteries you kind of just need penlight[1] and maybe luastd. Of course there's posix, lfs, socket, luasec and you're semi set.

I love that Lua can access file so simply using io.open, can Lua be used to delete, copy and paste folders?
https://github.com/lunarmodules/Penlight provides a bunch of functionality for stuff like that.

[discussion] Why don't more (any?) plugin authors use penlight?
However, there's already a widely known, well-tested library in the lua community called penlight that covers a lot of lua's "missing" functionality. It's got sane string manipulation, ergonomic tables, a basic class mechanism, functional programming, enums, exceptions, path manipulation, etc...

Trying Fennel for GTK apps and it's surprisingly good
As for batteries, there's things like penlight which comes with a huge set of pure Lua libraries inspired by Python. And, well, there's Fennel libraries with macros and more lispy style APIs.

Lua's Lack of “Batteries”
I'm very surprised there was no mention of Penlight in that article. Penlight, a supplemental standard library for Lua that is heavily inspired by Python's own standard library, has been around for years now:
