Functions under the Hood (Lua 5.1/Luau)

Hi!

I'm mostly posting this to see if anyone understands what the difference is between two or three different things within Lua 5.1 or Luau somewhere in the stack or under the hood. I can't decide whether this is a Help flair or a Discussion flair, so do let me know if it's more fitted for the Discussion tag and I'll see what I can do about it.

Anyways, I understand that this subreddit is mostly based around Lua - I'm mostly doing all of this in Roblox Studio, so it's more of a Lua 5.1/Luau question, but...

Why is:
local f; f = function() end
different from
local function func()
end
when inspected using debug.info() (similar to Lua's debug.getinfo())?

For example, when I call debug.info(1, 'n') in local f; function() end, it returns: ""
but when I call it in local function func() end, it returns: "func" (the function name)

Does anyone understand what's different between the two? I understand local f; function() end is in a sense an anonymous function, but why does it matter that much under the hood?

If this is too roblox-inclined, tell me and I'll happily move this post over to r/robloxgamedev or elsewhere.

Need A bit help with Neovim plugin development

I am working on a project called model-cmp.nvim, which used python to run LLMs locally and allow text autocomplete in neovim using the model predictions. The development is taking longer than expected, the model efficiency development is taking too much time, though I can handle that part. While keeping the modelapi in one hand, it is very difficult to develop actual plugin. So I was wondering if someone would like to handle the plugin development process. The link for the plugin is https://github.com/PyDevC/model-cmp.nvim

Doxygen Lua documentation help

I'm making a Lua interpreter with the Lua C API and want to make a documentation for it. Everything seems fine, besides writing the functions inside the library: e. g.: This is a function that is for Doxygen:

nil os.delay(number seconds)

I want it to show it as is, but instead, Doxygen parses it like this:

nil os delay(number seconds)

Basically, Doxygen treats the library (os) as a type (nil os delay, this is not what I want), instead of leaving it as is (which is what i want: nil os.delay)

Here are some similar documentation pages I found that do what I want to achieve:

http://onelua.x10.mx/vita/docs/en/group__adhoc.html

https://jcnmsg.github.io/LuaDEV-R0-PSP/original/spanish/html/group___i_n_i.html

I have spent all day trying to fix this, including issuing it to the Doxygen repo, but I haven't found any solution so far.

Why do Lua tables need commas?

Wouldn't the grammar still be unambiguous if tables didn't need commas?

After Python, which language should I learn??

I’m currently learning Python, and want to learn a new language after to make games as a passion project.
After I learn Python, should I learn GDScript to make games on Godot, or should I learn Lua to make games on Roblox?
Which would be easier or harder to learn?
Which would benefit me the most?

After learning Pico8 what is best next (Picotron, Playdate, Love2D or jump to Godot).

Like the noscript says, I'm in love with the Lua language when I started making small games in Pico8, and now I want to make something much bigger, or maybe do the same games but outside Pico8, to learn more advanced things. What is your recommendation? Thanks

I Wanna learn to program in Lua

Well, here we are. Sorry if you misread anything in this text. It's not my native language, so I want to learn to program in Lua. I've been really interested in this language. I've been doing some research, but I don't know how to get started. I speak Spanish, and the articles out there don't compare to the English ones. Could you please help me? I'd like to learn, but I don't know how. Could you send me articles, videos, or whatever, or explain it to me? That would be great.

How can I compile a single lua file into an exe?

I just want to compile a stand alone (vanilla) .lua into an exe. I tried using srlua but I just couldn't figure it out I guess. There were next to no instructions on how to set it up. I tried to compile the srlua.c into an exe with gcc but that threw an error saying it couldn't find lua.h. there were a few header files I could see it wouldn't be able to find, so I downloaded the lua src and tried to manually link them. To no one's surprise that didn't work. I've tried about 100 different things and nothing works

I Want to Learn

My son loves computers.

I've made a couple of super basic Scratch projects with him showing me the ropes and received more praise than I probably deserved.

That is the extent of my knowledge...but not the extent of my ambition. I really want to learn how to code. Like proper coding.

The kid and I love Roblox so I feel like choosing a first language connected to a shared passion might be best. So Lua....

I tried watching YouTube to get my feet wet only to find that nothing made sense.

Please help me. I need an introduction that starts at level zero. Where do I look/go/watch?

A Cross-Platform “Batteries-Included” Lua Networking Toolkit

This is my first time posting here—please forgive any mistakes or inappropriate formatting.

silly is a cross-platform “super wrapper” (Windows/Linux/macOS) that bundles TCP/UDP, HTTP, WebSocket, RPC, timers, and more into one easy-to-use framework.

Built-in network primitives (sockets, HTTP client/server, WebSocket, RPC)
Event loop & timers, all exposed as idiomatic Lua functions
Daemonization, logging, process management out of the box
Self-contained deployment (no C modules needed, aside from optional libreadline)

Check out the examples/ folder (socket, HTTP, RPC, WebSocket, timer) to see how fast you can go from zero to a fully event-driven service. Everything is MIT-licensed—fork it, tweak it, or just learn from it.

Catch output from function called via load(string)

Hey there,

I'm coming back to lua after some time away... I'm trying to call a constructor based on a string from some Tiled output. I've had success doing this using the `load` function - the constructor is being called - but I can't seem to get a reference to the object created. Here's some example code:

function AddElement(_type, _x, _y)
if (_type == null) then return end
local s = _type .. "(" .. tostring(_x) .. "," .. tostring(_y) .. ")"
local makeElement = load(s)
local e = makeElement()
table.insert(elements, 1, e)
print(#elements)
end

I am seeing output from print statements inside the elements' constructors, but the `elements` table is not increasing in size, and `e` seems to be nil. Any ideas?
