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.

Is there a free course on YouTube that could help a beginner make GUIs?
If you want to use GTK (works on Linux/Window/Mac, default for Gnome desktop), you will need to use LGI-module (https://github.com/lgi-devs/lgi).

Trying Fennel for GTK apps and it's surprisingly good
I'm using LGI, they're Gtk bindings based on GObject Introspection (A middleware to communicate with GLib-based libraries dynamically) meaning that they can access without hand-writed code to all the GLib-based libraries even if they were written in other languages like Vala, C, C++ or Rust.

How to send an external signal to Widget
Alternatively, awesome is build on top of lgi which exposes GLib objects introspection. It means you can reach in your lua code some objects/services exposed through GLib. https://github.com/pavouk/lgi

Can't build Awesome from source
This is because many people who tried to build from source had problems. LGI, one of awesome's dependencies, currently hardcodes the package search path used by Lua 5.1. Part of the reason for this is that Lua upstream intends Lua to be embedded, which means that detecting an installed Lua version properly is not easy.

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. However, there are several standard library packages for lua: batteries, Penlight, or the aforementioned lume. 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:
