Is there a standard package manager for lua?

Hello, I come from a coding background, but am new to lua(only ever wrote noscripts for aseprite).

I'm curious is there a standard package manager for lua?
ala bundler for ruby or mix for elixir.

Some context, I found a pretty cool looking game engine(love) and figured I'd make something to get a feel for it. The getting started guide suggests installing it system wide which seems bad and some quick googling for a package manager produced multiple results, so I wasn't sure where to start.

Figured it might be a dumb question with an obvious answer so worth asking before I research it myself.

Thank you everyone for the help.

Looking for a Lua Fullstack Developer - Serverless Web Apps for a German Startup

Hey everyone, i've posted here a couple of times about the platform that the startup i work for is developing.

It's a german startup called Tenum and we're looking for a Lua fullstack developer (preferably as a freelancer) to help us build serverless web applications on our platform. The platform is still under development, but already a great experience to get things done fast.

If you have solid experience with Lua and web development and would like to work with a new technology on various customer projects, I'd love to hear from you.

This would be the ideal process:

1. After you've contacted me here on Reddit or via email, we'll set up a quick call with the founder.
2. Then we'll show you the platform and discuss the details.
3. If there's a fit, we'll start working together.

We'd prefer someone whose time zone is well aligned with ours (CET).

If you're interested, dm me or email me at hello@tenum.ai with a short note about yourself and your experience.

Thanks a lot!

Downgrade lua 5.3 para lua 5.1 e luarocks

# Atualmente eu estou usando lua 5.3 já instalei alguns apps nele como vlc, neovim, etc

# Quero saber se existe uma maneira de desinstalar o 5.3 e instalar o 5.1 sem quebrar os pacotes já instalado. ai vem a pergunta porque quero dar um downgrade estou tentando renderizar imagens no meu terminal kitty com plugin do neovim eu consigo já redenrizar com terminal puro mas sempre tenho problemas porque o plugin do neovim só funciona com lua 5.1 e eu já uso o 5.3 a um bom tempo. Alguem tem alguma dica do que fazer?

What’s the difference between “else” and “elseif”?

I am a beginner who just recently started learning off YouTube.

Most of the things I can make out what they mean after watching some videos

But I still don't understand the meaning of the "elseif" statement

I know some degree of visual programming (scratch...), so I for sure know what the "if" and "else" statement means.

But for "elseif", I don't quite understand what the statement does

Like I can say things like

>variable = 2

>if variable == 1 then

> print("blah")

>else

> print("blee")

(correct me if I made a mistake in my example)

Something like this

I figured if I use "elseif", the results will be the same

So what's the purpose of the "elseif" statement?

Can one determine total gc memory allocated?

If I understand correctly, collectgarbage 'count' gives the amount of allocated memory at the time of invocation. Is there a way in standard Lua/LuaJIT to determine the total memory including that previously collected at the time of invocation? That is, is there a way without modifying Lua itself to determine/benchmark how allocation heavy a piece of code is over a particular run? I'm thinking of something like get-bytes-consed from the SBCL Lisp implementation. Something similar to *gc-run-time* might be nice too.

How do i make a configuration file that a lua reads from?

Hi, i want to make my lua noscript read from a .cfg or a .txt or whatever format is the easiest to toggle things inside it's menu

The code for what controls the checkboxes, sliders, dropboxes looks like this:

local Controls = {
checkbox1 = false,
checkbox2 = false,
checkbox3 = false,
checkbox4= true,
Dropdown1 = 1,
Dropdown2 = 1,
Slider1 = 90,
Slider1Input = "",
Slider1Editing = false,
}

What i want is to have somewhere my lua reads from to see what to toggle on and off as a configuration file for the lua noscript, how can i do this, hopefully i gave enough information for people to help me, if not please let me know

LUA state in 2025?

Hello everyone,

2024 is coming to an end and I'm quite curious about this, what is the current state of LUA in 2025? On the website of LUA, I feel like there's not much of an update. When I search LUA 2024 on Google, the result seems to stop at 2023. There are not many discussions, jobs for LUA also seem to be no result too. So I wonder, what is LUA going to be like in 2025?


The question seems to be vague, I hope you can understand as English is not my first language.

I want to build a small forum using Lua.

Hello!
I expressed my purpose in the noscript.
What library would you recommend to use?
Something like Python-Flask.
If it has basic support for creating endpoints, requests and templating I am happy.
I heard Lapis is the most mature.

Javanoscript "this" function but in lua?

I'm here in roblox getting stuck at this.

Javanoscript has this cool thing here where it is like

function button() {
print(this)
}

And the "this" will show whatever button executed this function, it can be fifty button with that function and it is a cool thing, but what about lua?

Button.TouchSwipe:Connect(function(SwipeDirection, Number, Processed)
print("??")
end)

How the hell do i do it, and roblox lua is a little different than lua right?

Help with inconsistent iterator behavior

I am familiar with the concept of iterators in other languages, but I can't figure out how to get normal iterator behavior out of lua tables. The top example works normally with string iterators, but the bottom does not with table iterators.

-- works
stringEntries = string.gmatch("text1,text2,text3", "(^,+)")
print(stringEntries)
-- function: 0x5627c89b62c0
print(stringEntries())
-- text1

-- does not work
tableEntries = pairs({
    name = {"John", "Jane", "Bob"},
    age = {30, 25, 40},
    city = {"New York", "Los Angeles", "Chicago"}
})
print(tableEntries)
-- function: 0x5627946f14f0
print(tableEntries())
-- stdin:7: bad argument #1 to 'tableEntries' (table expected, got no value)
-- stack traceback:
-- C: in function 'tableEntries'
-- stdin:7: in main chunk
-- C: in ?

I would expect it to return the next key value pair but it's saying the tableEntries iterator expected a table as an argument? What argument would I give to an iterator function created from a table already?

Is there some other normal table iterator function that yields a normal iterator instead of whatever pairs does/does not do?

Edit: Code got repeated twice, removed duplicate, added outputs
