Penlight
A set of pure Lua libraries focusing on input data handling (such as reading configuration files), functional programming (such as map, reduce, placeholder expressions,etc), and OS path management. Much of the functionality is inspired by the Python standard libraries. (by lunarmodules)

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 love packages/libraries do you guys currently use and consider essential for every project you guys made?
I really like baton for input, flux for tweens, and gamera for camera. My projects use gabe as a base for hotloading code changes and it works wonderfully.

A very simple class implementation in Lua for game developers
Gabe is a class and reloading system that I use with love2d but the class system has a local table of classes instead of putting them in global.

best game framework to learn?
It uses Lua which I find to be more dynamic and expressive than C#, java, or C++. I use gabe to hot load my code so I can change enemy behaviour in code, hit ctrl R, and the enemy starts using the new functions starting from its old state. Tough to set that up with one of those compiled languages!

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.

Opinions about the approach below to emulate "objects" in Lua :)
I prefer the table based approach because it allows hot reloading code for live objects. I use Gabe's classes to create objects and its hotreload code does the rest. Write some enemy code, playtest, find an enemy acting weird, write some debug UI, hotload, see your UI on the broken enemy without having to figure out how to repro. It's like magic.

I like making games, but I use scratch.
change code on the fly. Try c# script reloading in unity or Gabe in love2d.

Try My Game Spikes Are The Enemy On Ios
I use gabe because it's integrated into a hot reloading framework.

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).

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:
