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

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.

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
