This is how you define functions. In this example, "main" is the name of the function, and Int is the return type. My function takes no arguments. If I wanted to make a function that takes arguments, it might look like this:

add = Func(number1: Int, number2: Int): Int {
	return number1 + number2
}

This is a function that adds two numbers together, here's the same function in Python:

def add(number1: int, number2: int) -> int:
	return number1 + number2

Calling Functions

To call a function, you type a dollar sign (the $ symbol), then the name of the function, and then you pass any of your arguments inbetween paranthesis, like this:

add = Func(number1: Int, number2: Int): Int {
	return number1 + number2
}
...
later in my code...
...
$add(9, 10);

Here's a "Hello, World!" program in Plasma:

main = Func(): Int {
	$print("Hello, World!\n");
}

print is a builtin function, it's defined in every piece of code you write. It has the same formatting as the printf function in C, so if I wanted to print an integer I could do it like so:

$print("%i\n", 123);

Variables

To create a variable, it's as simple as:

name: Type = value;

There are several types in Plasma, which are: Int, Float, Bool, String

Here's another example:

name: String = "bob";
age: Int = 23;

To change the value of an already defined variable, you just have to provide the name, and then write an equals sign, like this:

-- defining the variable
age: Int = 23;

-- changing it later
age = age + 1;
