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.

Pluto, a Modern Lua Dialect
This is interesting, but lua needs a refresh.
I think berrylang shows a lot of promise now https://berry-lang.github.io/. The documentation has improved a lot and while it doesn't have a 'luajit' yet it has a lot of really interesting optimisation/reduction techniques.

Berry is a ultra-lightweight dynamically typed embedded scripting language
If like me you like to look at examples of code to get a feel for the language, take a look at https://github.com/berry-lang/berry/tree/master/examples

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...

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).

Thoughts on LUA?
Lua is a small language and its "standard library" is very minimal. This was one of my initial roadblocks. Lua's intended for embedding so usually the host program provides a broader standard library by exposing functions to lua.

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).

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:
