Is it better to declare the core module globally in an embedded environment?

My program exposes it's main functionality through lua, there is not that much of it so it's in one module. Now I'm wondering if it's better to expose it globaly, or should the user require the module themselves(one benefit of this would be no lsp warnings). I looked around and saw other projects doing this like love2d or neovim(I'm strictly referring to the module providing the core functionality), but I'm still not sure.

Luans - a Lua learning App inspired by Koans

Hello everyone

We’re excited to share that Luans has leveled up—version 2.0 is now live at [play.tenum.app](https://play.tenum.app).

Here’s what’s new:

* **More lessons** — a broader range of topics to help you build your Lua skills step by step.
* **Cleaner feedback** — clearer, more immediate answers when tests fail or pass, so you always know what’s going on.
* **Mission‑style format** and **Layout improvements**

We’d love your feedback on v2.0. We’re planning to implement user-submitted lessons, letting the community contribute topics and challenges. This would open the door for even more diverse content and learning paths.

Help figuring out "requires" with c++ and windows

Hello,

I'm reading a book that teaches Lua and C++ together (Integrated Lua with C++), and I'm having difficulty figuring out how to accomplish this portion of the book. They use a Makefile and create a file called Destinations.SO, which is a Unix thing (I'm using Windows). I'm trying to figure out what exactly it wants so it can read it correctly.

Destinations = require "destinations" -- This loads `destinations.so` and assigns the module to the Destinations global variable.

I'm getting " Failed to execute: noscript.lua:1: module 'destinations' not found:" and a bunch of locations saying "no file 'D:....."

I'm going to provide the snippet of the book, and hopefully that makes it clearer:

>So far in this book, we have only explicitly registered C++ modules to Lua in C++ code. However, there is another way to provide a C++ module to Lua.

>You can produce a shared library for a module and place it in Lua’s search path. When the Lua code requires the module, Lua will load the shared library automatically.

>To test the standalone module, in the folder where `destinations.so` resides, start a Lua interactive interpreter and execute the following statements:

>Chapter09 % ../lua/src/lua
Lua 5.4.6 Copyright (C) 1994-2023 Lua.org, PUC-Rio
\> Destinations = require "destinations"
\> dst = Destinations.new("Shanghai", "Tokyo") Destinations instance created: 0x155a04210 > dst:wish("London", "Paris", "Amsterdam") > dst:went("Paris")
\> print("Visited:", dst:list_visited()) Visited: Paris
\> print("Unvisited:", dst:list_unvisited()) Unvisited: Amsterdam London Shanghai Tokyo > os.exit()
Destinations instance destroyed: 0x155a04210

>The most important statement is the require statement. This loads destinations.so and assigns the module to the Destinations global variable.

>We started the Lua interactive interpreter in the same folder where the module binary resides because require will search the current working directory for modules. Alternatively, you can put the library in a system search path. You can check the reference manual to learn more about require and its behaviors.

>A standalone C++ module is useful when you need to reuse the module in the binary form across multiple projects or enforce code isolation on the C++ side, but this is just a design choice.

Any help would be appreciated, because this is driving me crazy.

Any simple ways a 13-year-old could earn money with Lua?

I’ve been learning Lua for about a year, mostly with Luau, and recently I’ve started using the LÖVE framework to make games. I’m 13 (in 8th grade), so I know I’m still pretty young, but I was curious: are there any simple or realistic ways for someone my age to make a bit of money with Lua coding?

setmetatable and index

I'm doing more on classes - and I'm making a class


MyClass = {}
function MyClass:new()
o = {}

setmetatable(o, MyClass)
self.index = MyClass


return o
end

function MyClass:myfunc()
print("myfunc called")
end


c = MyClass:new()

I realise the manual example uses 'self' rather than MyClass - but I'm not looking for inheritance yet.

And I'm wondering why I need both to set the metatable and index to MyClass. Just setting the metatable fills the metatable of c with fields named after the MyClass functions (eg myfunc) that point to the metamethods - so they should be callable? Yet calling them is calling nil. Why do I require index to be set as well?
I've read the manual on the index metamethod and I see how setting index to the MyClass table and the index metamethod is called if there is no field in the metatable - yet the metatable of c has the field myfunc in even if I miss setting index.
