Method Declaration

All functions in Morph are declared with the method keyword.

Basic Syntax​

// Without 'is' — recommended for methods
MethodName method() {
    // body
}

// With 'is' — also valid
MethodName is method() {
    // body
};

Convention: Omit is for method declarations. Use is for variable assignments.

With Parameters and Return Type​

Add method(a as int, b as int) as int {
    return a + b;
}
  • Parameters: name as type, separated by commas
  • Return type: as type after the parameter list
  • No return type means the method returns nothing (void)

Calling a Method​

result is Add(3, 5);
Print(result);      // 8

Entry Point​

The Init method in src/Main.mx is the program entry point:

Init method() {
    Print("Hello Morph!");
}

No return type, no parameters. Automatically invoked by the runtime.

Method Naming Rules​

  • Method names must start with an uppercase letter (PascalCase)
  • Minimum name length: 4 characters (configurable)
CalculateSum method(a as int, b as int) as int {   // ✅ correct
    return a + b;
}

add method(a as int, b as int) as int {   // ❌ must start uppercase
    return a + b;
}

Methods in Classes​

Inside a class, methods are declared the same way:

Player class {
    GetName public method() as string {
        return "Player One";
    }
}
