How bad is it to use local self = {} instead of the vastly popular local M = {}

I've just start learning lua mostly for using it in neovim. As I expand my knowledge to writing bigger modules, I noticed that most Lua tutorials use the following convention:

local M = {}

<..code..>

return M

However, to my naive self, self seems a lot better. Consider:

local M = {}
M.bar = 2
function M:foo()
    return self.bar + 1
end
return M

vs

local self = {}
self.bar = 2
function self.foo()
    return self.bar + 1
end
return self

1. Notice how foo continues using self so that it "feels" like the former (perhaps more OOP-ish) way of doing things.
2. It helps everywhere you want to pass foo as a callback in other modules:

p = require('a.b.mymodule')

some_function({callback = function() p:foo() end})
---vs (IMO much better)
some_function({callback = p.foo})

So I only see advantages to doing it the local self = {} way. Why is this not popular or not recommended? I'm assuming it'll break something but not sure what.

Need help with images

I am incredibly new to Lua. Like so very very new. like i know nothing. I am learning to code, my programs are love2d to load the game and visual studio to write it

I have the image i want in the file (as seen below, ignore the name for it i was tired.), but im not sure how to load it onto the actual screen of the game. Ive tried loadfile(yummy.jpg, bt, any) after the function with an ending but nothing happens. help is very much appreciated :)

Syntax conventions, string.foo(bar) vs bar:foo()

I'm primarily a Python programmer but I've been learning Lua for various reasons and I am coming to appreciate its sleek nature the more I use it.

That said, I'm grappling with the different syntax options that Lua provides. In the Pythonic mantra, the line There should be one-- and preferably only one --obvious way to do it. comes to mind; while it is nice to have options I feel like I should choose one way or another and stick to it. Is this how Lua programmers typically operate?

If I were to stick with one, which to do? Again referencing the Pythonic way, we have Explicit is better than implicit. and Sparse is better than dense. and Readability counts., which to me would point to using string.foo(bar) instead of the : syntactic sugar, but it also isn't quite as compact.

What are your thoughts? Am I just overthinking things and applying Pythonic logic where I shouldn't? How do Lua programmers typically write their code?

I coded the Collatz conjecture in Lua, please give feedback

I am a lua developer and to test my abilities I decided to code the Collatz conjecture, it's available on GitHub
It's a simple code but I am just testing my skills, if you find any way I could make the code better tell me.
Thanks

Help please (scoping)

What is scoping and is it really essential to know when you noscript?

I really can’t understand it so I’m planning to learn it when I understand more things

Or do I have to understand it before I get into more stuff?

Need to edit a noscript so it only runs on Weekdays

I know absolutely nothing about noscripting. I was able to take a sample noscript and edit it to turn outlets on a network power strip on and off at certain times, but I don't know how to tell it to only run on weekdays. The noscript is

function outletonschedule()

for i,t,data in event.stream(event.localtime({hour=10,min=00})) do
outlet[1].on()
end
function outletoffschedule()

for i,t,data in event.stream(event.localtime({hour=17,min=00})) do
outlet1.off()
end
end

Reddit formatting is mangling it a bit, but those are two commands to turn outlet 1 on at 10a and off at 5p.

Can anyone show me how to edit the above to only run M-F?

Thank you

Lua Programming Gems book for a newer Lua programmer?

I'm still fairly new to Lua and have been working my way through the official book, remaking some of my Python programs and writing new noscripts to learn the language. I came across Lua Programming Gems from Feisty Duck and wanted to see what you guys thought of it. Would it be good for an otherwise experienced programmer learning Lua or should I hold off until I know the language better?

Is lua a good option for me?

Hi friends, i'm a Java/kotlin developer, most of the time i'm using Spring boot to make projects.

But recently i was searching for an easy 2 learn language for me to use It as a lab language, to learn web architecture without the opinative way from the Spring, and learn some other things like graphical programming, games and desktop programming(and a bit of DSA too).

My First ideia was lua because everyone say that Its a simple language and because Its from Brazil(my country).

I would appreciate any opinion.
