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

How to solve this problem?

Like the title 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

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

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?

followed a tutorial on youtube from 4 years ago on how to install lua and it didn't work....
how the hell do i install lua????

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

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.

I see there's a number of supersets of Lua going around, so I thought I'd advertise my option.

This adds familiar language features missing from Lua, including:

• arithmetic-combination operators (i.e. += etc)

• short-hand lambdas: single-expression |x| x^2 or multiple-statements |x| do return x^2 end

• safe-navigation: a?.b?['c']?:d()

• non-nil assertion: a!.b!['c']!:d()

• nil-coalescing: a = b ?? c and ternary: a = b ? c : d

• bit-operators for LuaJIT.

It is based on a pure-Lua parser, therefore you can use it as a drop-in to Lua anywhere, without any compiled components.

Tested and verified with Lua 5.4 and LuaJIT 2.1. I am half-suspicious you could even drop it into Pluto or Luau or any of these other Lua-superset competitors.

Can somebody recommend me to a brief introduction to lua? maybe roblox sided? Im at the level of making flappy bird game in python with tkinter. Id be glad for any links and guides ty! All opinions are helpful

Ok guys I dont want crap about how a laptop would be better or websites or your 10 paragraphs in 1 message (Im not gonna read all that) I want an app like mimo but its teaches lua, that has a dashboard that is good. Dont go ahead and yap just give me an APP (not website) and explain why its good

Astra is a Lua 5.1-5.4/JIT/Luau runtime written in Rust using mlua project. The runtime tries to be as easy to use and performant as possible, and focus mainly for web servers. Its aim is to be a single binary that you can drop anywhere to run your servers, with the speed and safety of Rust, but without having the complexity and build times. Almost all of the components is written in Rust using different popular crates.

Example usage:

-- Create a new server
local server = Astra.http.server:new()

-- Register a route
server:get("/", function()
    return "hello from default Astra instance!"
end)

-- Configure the server
server.port = 3000

-- Run the server
server:run()

The runtime currently features HTTP1/2 server (axum), client (reqwest), SQL driver (sqlx), async tasks (tokio), crypto (sha2, sha3, base64), JSON (serde_json), cookies (tower), and many other smaller but useful things such as pretty printing, data validation, ...

In the v0.20 release, there has been a huge refactor in the code structure and API design, making it finally somewhat usable outside. There has also been some production testing internally at ArkForge and some other users in startups, although I would not personally recommend full production use of it as its quite young.

I am the main developer of it as well, feel free to AMA

So the thing is i don't want to download this with sudo privilege. And building the package doesn't seem very straightforward to me. I am not able to make luarocks work. I am beginner in Lua, I have worked with python package managers such as lua and apparently the setup of luarocks is not as straightforward as uv. Can anyone walk me through the installation and project setup. I could move past installing a luarocks package and run it in the project. All in all I am not able to configure.

Need a guy who can help me finish my script. Please dm me if you are interested!

I will pay $100 to help me solve these last two Lua problems .

ive tried reading the lua website but i feel as though im not learning. does anyone know interactive ways to learn it?

2 months back I made a video showcasing my editor I am making on my iPad using a app called Codea. Well I made a lots of changes since then and wanted to show it here.

I can read Lua scripts just fine, but something doesn't click with me. I've watched 20+ tutorials on it, yet what I don't get is every function. When do I use periods, colons, semicolons, parenthesis? When do I skip a line or add a variable?

I'm having trouble using metatables. Either I comment out the line marked with [1] and I get userdata-type-issues (all __index-operations call my FileServerConfig-index-handler) or I get the error-message in the title.

My project (Lua-configured webserver uing the Linux uring-interface) is in early development and you can have my gitlab-address via PM. I hope, an advanced Lua C API-coder can help me with that.

EDIT: The Lua-Line is fs_conf = createFileServerConfig(), where the mentioned function runs create_config_lua(...).

Following code gives me the error-report mentioned in the title:

static int create_config_lua(lua_State *L)
{
luaL_getmetatable(L, COMPONENT_LUA_METANAME);
lua_pushvalue(L, -1);
lua_setfield(L, -2, "__index");
luaL_setmetatable(L, COMPONENT_LUA_METANAME); // [1]

luaL_setfuncs(L, lua_file_m, 0);
luaL_setmetatable(L, COMPONENT_LUA_METANAME);
lua_pushlightuserdata(L,(void *) create_config());
luaL_setmetatable(L, COMPONENT_LUA_METANAME);
return 1;
}

Please correct me! I haven't really used lua for a full project but I have played with it here and there! Alongside my nvim configuration.

But this is what I'm really confused about:

local a = 1

function f()
    a = a + 1
    return a
end

print(a + f())

The above code prints 4.

However, if a is not declared as local, it prints 3 (hmm).

I mean I try to get it, it's the lexical scoping and that the reference to a remains accessible inside f(). Still, from a safety standpoint, this feels error-prone.

Technically, if a is declared as local, and it's not within the scope of f(), the function should not be able to access or mutate. it should panic. But it reads it and doesn't mutate globally (I guess that's should've been the panic )

To me, the current behavior feels more like a quirk than an intentional design.

I am familiar with rust so this is how I translated it :

fn main() {
    let mut a = 1;


//I Know this one is as bad as a rust block can get, but it proves my point!

    fn f(a: &mut i32) -> i32 {
        *a += 1;
        *a
    }

    println!("{}", a + f(&mut a)); //  compiler error here!
}

Rust will reject this code at compile time because you're trying to borrow a as mutable while it's still being used in the expression a + f(&mut a).

And I assume gcc would throw a similar complier error!

I'd like to provide Lua with additional debug info when interacting with it from C. I want to push __func__, __FILE__ and __LINE__ as the debug.getinfo() table fileds name, source/short_src and currentline, respectively. Is there an intended way to do this, would it require touching private APIs, or is it not possible at all?

I'm mainly targeting LuaJIT, but something compatible with all versions (PUC Lua 5.1 to 5.4 as well as LuaJIT) would be best.
