Is there a way to push custom debug information from the Lua/C-API?

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.

Grid and table question

I'm creating a 3d utility and ran into a dead end.

In the image the yellow bars represent one grid on the terrain. There is no set amount as to how many there are or can be. I'm trying to make a table aaccessible by these unset number or grid bars.

I originally tried something like -

grid = {}

for t=1, AmtOfBars, do ; grid[t\] = {} end

But when i try to add to the table like this -

table.insert ( grid[1\][1\], {

somedata = blah,

somedata2 = blah

})

I get runtime errors.

Any advice on how to set up this needed table > Thanks.

Lua's scoping behavior can be quite surprising. Bug or by design?!!

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!

New to lua

I can read Lua noscripts 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?

C API: "bad argument #1 to '?' (FileServerConfig expected, got FileServerConfig)"

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 noscript.

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 noscript:

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;
}

Ultra Engine 0.9.9 Released

Hi, I just wanted to let you know the new version of my Lua-compatible game engine has been released: https://www.leadwerks.com/community/blogs/entry/2872-ultra-engine-099-adds-a-built-in-code-editor-mesh-reduction-tools-and-thousands-of-free-game-assets/

https://preview.redd.it/02adopcqz53f1.jpg?width=1280&format=pjpg&auto=webp&s=3ce16cd9b6cd01351510a0da158ee756c67b5f77

Based on community feedback and usability testing, the interface has undergone some revision and the built-in code editor from Leadwerks has been brought back, with a dark theme. Although Visual Studio Code is an awesome IDE, we found that it includes a lot of features people don't really need, which creates a lot of visual clutter, and a streamlined interface is easier to take in.

https://preview.redd.it/iabye3tvz53f1.jpg?width=1960&format=pjpg&auto=webp&s=6631d4fc6ca17e138e1777819c3846fd6ab98454

A built-in downloads manager provides easy access to download thousands of free game assets from our website. Manually downloading and extracting a single zip file is easy, but when you want to quickly try out dozens of items it adds a lot of overhead to the workflow, so I found that the importance of this feature cannot be overstated.

A mesh reduction tool provides a way to quickly create LODs or just turn a high-poly mesh into something usable. This is something I really discovered was needed while developing my own game, and it saves a huge amount of time not having to go between different modeling programs.

Atualmente uso esse noscript;


local Spray_Randomize = math.random(29, 31)

local AK47_Pattern = {

{ x = 1, y = 1 }, { x = -1, y = -1 },

}



EnablePrimaryMouseButtonEvents(true)



function OnEvent(event, arg)

if event == "MOUSE_BUTTON_PRESSED" and arg == 1 then

if IsKeyLockOn("capslock") then

repeat

Sleep(9)

MoveMouseRelative(0, 6)

Sleep(9)

Astra v0.20 released - A Lua 5.1-5.4/JIT/Luau web server runtime

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

Can anyone tell me how to install lua and luarocks in user environment on Linux?

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.
