Functions

Functions are central to structuring code in Embr, allowing you to define reusable blocks of code.

In Embr, functions are first-class citizens. This means they can be treated in the same way as any other data type!

Defining Functions​

In Embr, functions are defined using the fn keyword. This is followed by the function name, a pair of parentheses () indicating parameters, the function's optional return type denoted with @<type>, and the function body enclosed in braces {}.

Returning​

All functions in Embr have a return type. If a function doesn't return anything, then its return type is void. While you can specify your desired return type, it is completely optional at this time.

Calling Functions​

Functions can be called by just referring to the name of the function, followed by a pair of parentheses that contain any applicable arguments. For example: my_func(420, 69);

Syntax​

The basic syntax for defining a function in Embr is as follows:

fn my_func() @void {
  // function body
}

fn func_two() {
 // function body 
}

Example​

Here is a simple example of functions in Embr:

fn add_ints(x, y) @int {
  return x + y;
}

fn main() {
  out add_ints(420, 69);
}
