Modules

Using multiple source files ("modules") is generally a good idea. Items from other files can be accessed with :: or with use (wildcards Mod::* are supported!), the same as Rust:

// One.bt
let one = 1;
fn main() = Two::doStuff();

#![allow(unused)]
fn main() {
// Two.bt
use One::one; // One::* would also work
extern fn println(x: str) = "System.out.println";
fn doStuff() {
    println("two: " + (one + one));
}
}

Circular dependencies are allowed (at least, almost all the time). Modules can be nested in directories, and module paths are defined relative to the root bytec directory that all your source files are in - this lets the compiler search the filesystem for a module when you use it for the first time. So with the example layout from earlier:

• bytec
  • common
    • Common.bt
    • Paths.bt
  • bot_one
    • RobotPlayer.bt
    • Soldier.bt
  • bot_two
    • RobotPlayer.bt
    • Miner.bt

We can use items like so:

#![allow(unused)]
fn main() {
// bot_one/RobotPlayer.bt
use common::Common::RobotController;
use bot_one::Soldier;

fn turn(rc: RobotController) {
    Soldier::turn(rc);
}
}
