How do I use a module which is defined at runtime in a function?

[frosty phoenix]

As the title says, I will provide code later

[hollow onyx]

What is a module in this case

[frosty phoenix]

Something like std or such that contains functions

[hollow onyx]

You can't define a module at runtime

[frosty phoenix]

Oh

[hollow onyx]

A module, for the purposes of zig code, is just a namespace with its own import table, which is just a struct type

[frosty phoenix]

Ye I'm kinda new to zig lol

[hollow onyx]

What are you trying to do?

As in, what problem are you attempting to solve?

[frosty phoenix]

I wanted to see if I could use zig to write UEFI applications cause dealing with linking something like gnu-efi was annoying, I want to use UEFI's con_out in a function

[hollow onyx]

Pretty sure you can just write zig uefi applications

[frosty phoenix]

That's what I'm doing

[hollow onyx]

There's a whole uefi namespace in stdlib

[frosty phoenix]

That is what I'm using, but uefi.system_table.con_out is defined at runtime

uefi is just std.os.uefi

[hollow onyx]

What do you mean? Do you mean it's a var?

That just means it's a global var

[frosty phoenix]

It's a const, but it's not comptime, it's runtime

[hollow onyx]

Like extern const?

If you just mean a plain const, it can't be defined at runtime if it's global, internal zig globals are always initialized at comptime

[frosty phoenix]

this

[hollow onyx]

What's the problem

That's a var which is assigned before main is called, in start.zig

So by the time you reference it, it should already be defined, unless you've overriden main

Oh I think I know what your problem is

Are you declaring const con_out outside of a function @frosty phoenix?

Or rather, inside a struct or in the file namespace?

[frosty phoenix]

no

im doing it in main

[hollow onyx]

Well then the question again comes, what's the issue?

It should just work

[frosty phoenix]

i got it working by just using the full uefi.system_table part in the function
