Luau Module

[DasLixou]

How can I export a function / make a module with luau?
I get compile_error!("Luau does not support module mode");
Is there any possible way to make luau call rust code?

Luau itself does not support loading binary shared libraries.
In theory it should be possible, but I need to add support to mlua calling dlopen to load module symbols.
I was considering adding this functionality, but not sure will it be in 0.9 or later.

So there's currently no possible way of doing modules? I'm new to lua so this idea might be stupid but when trying to understand the module thing.. couldn't I just make a table and instead of making it a module I just smash it in a global?

Adding module support for Luau would be very useful, for my project Lune which is a standalone runtime based on Luau, I would like to let people create native speed modules, require them as normal, but it's currently not possible. This leads to me having to integrate any functionality that needs native code into the full runtime but I would like the runtime to remain pretty small.

Also, a related question - would it be possible to make mlua modules portable? So that a user can distribute a single file / package and any os/arch that is supported by mlua can run it?

I think support for this would be amazing and now that 0.9 is out I hope you work on it 👍

I work on native modules for Luau, should be in the next version.

would it be possible to make mlua modules portable?

I don't think this is a question for mlua, rather for core Rust/LLVM :)

This is supported now since v0.9.2
