Functions

🔗Function definition

Functions are reusable blocks of code that perform a specific task. They allow you to organize your code, avoid repetition, and make it more modular and maintainable. In Tim, function names are case-insensitive, so greet, Greet, and GREET would refer to the same function.

You can define functions using the fn or func keywords, followed by the function name, parameters, return type, and the function body. For example:

fn greet(name: string): string =
  return "Hello, " & $name & "!"

echo greet("Tim Engine")  // Output: Hello, Tim Engine!

🔗Function overloading

Tim Engine supports function overloading, which means you can define multiple functions with the same name but different parameter lists. The correct function will be called based on the arguments passed. For example:

fn greet(name: string, age: int): string =
  return "Hello, " & $name & "!" & " You are " & $age & " years old."

🔗Aliases

You can define functions using the fn or func keywords. For example:

fn greet(name: string): string =
  return "Hello, " & $name & "!"

// or, using the curly braces syntax
func greet(name: string): string {
  return "Hello, " & $name & "!"
}

🔗Mixing with HTML elements

HTML elements cannot be defined inside a function body. Trying to mix HTML elements inside a function body will result in a CodeGenError:

'HTML' can only be used inside a macro [CodeGenError]

Sure, you can return a string that contains HTML, and trick the engine into rendering it as HTML, but that's for amateurs!
