Numpy for luau?

Hello all!

I plan on implementing add-on support for my pet project, and so far Luau looks like the most battle tested solution! I love the sandboxing and the type checking features!

Performance of generating 5 242 880 numbers (math.noise), by default, is 0.6 sec, vs 0.19 in cpp.

I managed to get a primitive array type working when I realized the bottleneck is the stack between the Lua and the Cpp world. With this I managed to get the runtime down to 0.26, which is good for an interpreted language.

https://github.com/luau-lang/luau/discussions/1994

Is there a numpy-like library I can use with Luau? I can implement the methods more or less but I feel like I would duplicate work and my version would be sub standard.

I found numlua and lua-linear, but both seems abandoned.

A Lua Style Guide for the Community

Hey everyone,

I’ve been working on a **Lua style guide** and wanted to share it with the community.
The goal is to improve code readability and consistency, and to provide a reference that teams or individual developers can adopt.

The guide covers things like:

* Naming conventions
* Formatting (indentation, whitespace, line breaks)
* Table and function usage
* Performance tips
* Common pitfalls and best practices

You can check it out here: [https://github.com/ShaharBand/lua-style-guide](https://github.com/ShaharBand/lua-style-guide)

This isn’t meant to be the “one true way” to write Lua, but rather a starting point for discussion and refinement. I’d love feedback, suggestions, or contributions—whether you agree, disagree, or have alternative conventions that work well for you.

Hopefully this can grow into something the Lua community finds useful, especially for newcomers who want a clear reference on writing clean Lua code.

What do you all think?

I’m trying to make an Animal Crossing type Roblox game but idk how to code (Roblox code is Lua code. Username on Roblox is WigglesWantsCheese)

I’ve been dreaming of a game like animal crossing for months now but I don’t know how to code. I’m also rlly broke so if you want to do it 4 free. Or we can split the profit from the game. Think of me as…. The animator and the music guy. But idk how to import the animations to the proper sequences

Is there any discord server for sharing lua code?

I know about the Libera channel and the mailing thing, but I don't really like the format of those.

I considered just posting exercise solutions and etc here, but the sub doesn't have that many posts, so it would become quite spamy.

TLDR: where should I share my code to know if I am doing best practice/just to talk about it?
