V module as cross platform compatible

[nedimf]

Struggle

I have been playing with Rust integration for iOS, and one thing I noticed is that syntax wise it sucks.
Why? Because Rust uses C types to actually extern methods from library to end user.
Syntax wise it could be this:

#[no_mangle]
pub extern "C" fn give_me_letter_a(count: c_ulong) -> *mut c_char {
    let string = "A".repeat(count as usize);
    let cstring = CString::new(string).unwrap();
    cstring.into_raw()
} 

Solution

This could be solved with V. V exports .c files from .v file with ease. Issue is module that are written in V that actually include other modules does not export to .c files, there for .a files can't be created. And this is where issue blocks this idea.

Why would this be beneficial for V?

Imagine writing V module that runs on iOS, Android and ASM. This will make building cross platform modules reality.

I have written CLI that compiles V module into arm64/x86_64 static library and generates header files for use in iOS project.
vmob CLI

Thanks @nedimf - that tool might come handy soon 😉.

@dumblob let me know if it works for you. There might be issues, because it's not well tested yet

[dumblob]

Sure. That'll take some time in my case as there are tougher challenges in my life to tackle first.
