Typehint comments possible syntax

Hi Friends! Recently I told here about my meek attempt to make small "syntax sugar" additions to Lua source code and there was one curious comment suggesting that "type hints" on function arguments and return may be useful addition too.

While I have no skills to make such type-hints actually verify value types (in runtime?) of course it is easy to add them as a kind of special comment, e.g. so that programmer use them as reminder (and perhaps later some external tool for checking types could be devised) - I used colon to separate them (the typehint itself could be any identifier, except reserved words).

function hash(s:str):int
-- ...
end

As they are optional this is still compatible with original Lua and addition to the code is less than ten lines.

However I wonder - colon is used in Lua for different things (table-related case particularly) - seemingly this should never cause any semantic/syntactic "collision" but perhaps I'm wrong and missing something?

Project could be seen here: https://github.com/RodionGork/lua-plus/ (and could be tested online, by the way, if you follow the links to Lua-emcc - I decided to add these "amends" here).

I just downloaded VS Code on my steam deck but Lua doesnt work

I checked my steam os terminal and it says Lua exists but whenever I try using the 'lua -v', it says the lua command doesnt exist. I tried every way to download lua on VS Code like changing the shell but nothing works. How do I fix this?

Lua to apk

Hello,



I apologize in advance if this isn't the right place, or if the answer already exists, but I couldn't find anything. Maybe I didn't search properly.



I made a small, insignificant game in Lua (which taught me the language, which was one of the two goals). This game is just for me and a few friends.



I just wanted to make a small game on an Android phone to keep me busy while commuting.



The game isn't finished, but it's testable, and I'd like to try it on a mobile phone. But I'm a complete idiot and I don't understand how to do it at all. Is there an easy way to generate an APK so I can share it with my friends? I know you can launch it with a .love file and a dedicated application, but it's not practical for distributing it to my friends, and especially the game launches in landscape mode even though it's designed for portrait mode, making it unplayable because everything overlaps.



Thank you in advance for your help.

Saving content of the program

Hi! I learned lua a couple years ago but I don't practice often. One time i tried to create a diary in lua using löve2d to make the UI, but I struggled to make a saving function. I didn't used any other libraries unless the base lua and löve2d. I know that exists the table io but I struggled to use it. Can somebody help me?

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
