A programming language focused on performance and simplicity.

// Basic variable declaration and arithmetic operations
int a = 20;
int b = 10;
double c = 25.5;

// Mixed-type arithmetic, result is double
double result = a - b * c;

print "Result: " + valueToString(result);

// Boolean logic and type inference
bool isTrue = true;
bool isFalse = false;
print valueToString(isTrue and isFalse);

// String concatenation
string greeting = "Hello";
string target = "World";
print greeting + ", " + target + "!";

// Function declaration with parameters and return type
function calculateArea(double length, double width) double {
    return length * width;
}

// Function returning void (no return value)
function greet(string name) void {
    print "Hello, " + name + "!";
}

// Recursive function example (Factorial)
function factorial(int n) int {
    if (n == 0) {
        return 1;
    }
    return n * factorial(n - 1);
}

// Function call and variable assignment
double roomArea = calculateArea(10.5, 8.0);
print "Room area: " + valueToString(roomArea);

greet("Sapphire User");

print "Factorial of 5: " + valueToString(factorial(5));

// Class declaration with fields and methods
class Button {
    string label;
    bool isClicked;

    function click() void {
        this.isClicked = true;
        print this.label " was clicked!";
    }
}

// UI application structure (requires --no-console flag for packed executable)
function updateUI() void {
    UI.SetNextWindowPos(50, 50);
    UI.SetNextWindowSize(300, 150);

    if (UI.Begin("My App")) {
        UI.Text("Welcome to Sapphire UI!");
        class myButton = Core.createInstance("Button");
        myButton.label = "Click Me!";

        if (UI.Button(myButton.label)) {
            myButton.click();
        }
    }
    UI.End();
}

// Accessing system environment variables
string pathVar = System.getEnv("PATH");
if (pathVar != nil) {
    print "PATH variable: " + valueToString(pathVar);
} else {
    print "PATH variable not found.";
}

// Working with dynamic arrays (lists)
class myList = ListUtil.create();
ListUtil.append(myList, "apple");
ListUtil.append(myList, "banana");
ListUtil.append(myList, 123);

print "List element at index 0: " + valueToString(myList[0]);
print "List length: " + valueToString(ListUtil.length(myList));
