Builtin

Built-in functions are globally accessible and do not need to be imported. They are generally declared in the builtin_temp.n file.

print/println

Definition:

fn print(...[any] args) {}

fn println(...[any] args) {}

Only bool/string/number types are supported for printing. Compared to print, println adds a newline character \n and separates each argument with a space.

Example:

println("hello", true, "world")

// output:
// > hello true world
// >

errort

Definition:

type tracet = struct {
    string path
    string ident
    int line
    int column
}

type errort = struct {
    string msg
    [tracet] traces
    bool has
}

We have already encountered this structure in the error-handling section.

sizeof

int len = sizeof(int) // 8
int len = sizeof(f32) // 4

sizeof is not a built-in function per se because its argument is a type. You can think of sizeof as a built-in macro. Essentially, it is equivalent to writing sizeof int.
