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
Here's the GitHub: https://github.com/Gs-pt/Collatz-conjecture?tab=readme-ov-file

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?

Would learning Lua effect my c++ learning journey

So i wanna learn Lua to use it on fantasy console and maybe make some Roblox games, I heard it was really easy but I'm afraid it could effect my c++ learning journey

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.

Looking for someone that could do a Serious Sam 4/Serious Sam Siberian Mayhem dynamic bones mod which mainly consists of Lua noscripting.



There was a mod of it done in an earlier game that uses the same engine, here's the link to the mod, do let me know if it's possible to do it in the newer games too! https://steamcommunity.com/sharedfiles/filedetails/?id=1304802396

How do I noscript for Roblox?

Can you guys help me please, I really wanted to make a noscript for Roblox but I don't know how to do it, in fact I don't understand anything about programming and I don't have a PC to do this, but if anyone knows how to make a noscript for Roblox on their cell phone, please teach me how to create one, I would like to take a course for that but it's very expensive and I can't afford one.

I need help compiling a program from GitHub.

I want to decompile several Lua files. I found a page, luadec.metaworm.site, which had a GitHub repository: https://github.com/metaworm/luac-parser-rs

, so I went there, and that led me to believe it could be compiled, so I tried it (I've never done it before). This program uses Rust; I downloaded everything, even the night version, and it doesn't work when compiling. I got these errors, and of course, I don't know anything about this:

let (mut input, out) = le_u8(input)?;

...

(input, out) = complete::le_u64(input)?;

p.as_ptr().sub_ptr(input.as_ptr())

The thing is, I want to remove the censorship from a game, and I need to create a file to batch decompile it.

Looking for a better pure Lua library for handling large numbers

Hey everyone, I’m looking for a pure Lua library to handle really large numbers, something easier to use.
The old library I was using (int) sometimes loses precision when dividing large numbers, so I need something more reliable.

Anyone has recommendations or alternatives?

Hello. Starting from scratch, new to Lua, and coding in general. Where should I start?

Basically what it says on the tin, I hope to reach the end goal of creating a boat mod for project zomboid build 42 (despite the great difficulties that will come with it as seen from those who had already done it in b41), and coding games on roblox as well, and since Lua is required for both, I am here. Advice appreciated!
