Modules and FFI¶

Modules: realm¶

realm math {
    craft add(a: i32, b: i32) -> i32 {
        send a + b;
    }
}

Imports: bring¶

bring "std.fs";
bring "std.os";

craft main() -> void {
    make f = fs.open_file("x.txt", "r");
    os.run("echo hello");
    send;
}

C FFI: extern craft¶

Call C library functions:

extern craft fopen(path: str, mode: str) -> link void;
extern craft fclose(stream: link void) -> i32;

craft main() -> void {
    make f = fopen("data.txt", "r");
    check (f != 0) {
        fclose(f);
    }
    send;
}

Passing Structs¶

Structs are passed by value by default. Use link T for pointers when interfacing with C.
