Hello World in KSL

Ah yes, the traditional “hello world” program. The hello world program seems to be something that a lot of developers end up building, how strange, this should be investigated…

Let’s build it!

So first, we’re going to need a main function, our entry point.

fn main() -> void {}

Since we don’t need our main function to return anything we can just set the return type to void (notice the -> after the parenthesis and before void?)

We’re also writing to the console, so we’re going to need our good old standard io module. Go ahead and add it with: using std.io; You really should do this at the top of the file (it’s best practice,) but really anywhere works.

That should give us access to the writeln function, so let’s finish off your “World, Hello?” program.

using std.io;

fn main() -> void {
	io.writeln("World, Hello?");
	return;
}

Isn’t that awesome!! If this wasn’t torture then you should check out some other tutorials and learn some more about KSL! It might take some time but don’t give up!!!
