void main()
{
    // Start the server on port 8080
    listenHTTP(8080, (req, res) {
        res.write("Hello, world!");
    });

    // Run the event loop
    runApplication();
}

In this example, Vibe.d creates a web server that listens on port 8080. When a client makes a request, it responds with “Hello, world!”. The runApplication() function runs the event loop, which is essential for handling asynchronous I/O operations in Vibe.d.

2. Mir

Mir is a high-performance library for numerical computing. Below is an example of using Mir for matrix operations:

import mir.ndslice;

void main()

    // Create two 3x3 matrices
    auto A = matrix([1, 2, 3, 4, 5, 6, 7, 8, 9]);
    auto B = matrix([9, 8, 7, 6, 5, 4, 3, 2, 1]);

    // Perform matrix multiplication
    auto C = A * B;

    // Print the result
    writeln(C);
}

In this example, Mir is used to create two 3×3 matrices and multiply them. The result of the multiplication is printed to the console.

3. D-step

D-step is used to create bindings to C/C++ libraries. Here’s an example of how you might use D-step to generate bindings for a simple C function:

• First, you need a simple C function (example.c):

#include <stdio.h>

void sayHello() {
    printf("Hello from C!\n");
}

• Then, use D-step to generate the D bindings (assuming the C function is compiled into a shared library).
• In your D code, you can use the generated bindings to call the C function:

extern (C) void sayHello();

void main() {
    sayHello(); // Calls the C function
}

This example demonstrates how to use D-step to call C functions from D. The binding generation step is done with D-step but is omitted in the example above for brevity.

4. Arclib

Arclib provides concurrent data structures like lock-free queues. Here’s an example of using a lock-free queue with Arclib:

import arclib.concurrent;

void main()
{
    // Create a lock-free queue
    auto queue = new LockFreeQueue!int;

    // Enqueue some elements
    queue.enqueue(10);
    queue.enqueue(20);
    queue.enqueue(30);

    // Dequeue and print the elements
    int value;
    while (queue.dequeue(value)) {
        writeln(value);
    }
}

In this example, a LockFreeQueue is created and used to enqueue and dequeue integers. Arclib ensures thread-safety without the need for locks, making it ideal for concurrent applications.

5. DAlgebra

DAlgebra allows symbolic mathematical computations. Here’s an example of using DAlgebra for symbolic differentiation:

import dalgebra;

void main()
{
    // Create a symbolic expression
    auto expr = symbol("x")^2 + 3*symbol("x") + 2;

    // Differentiate the expression
    auto derivative = diff(expr, symbol("x"));

    // Print the derivative
    writeln(derivative);
}

In this example, DAlgebra is used to differentiate the expression x²+3x+2 symbolically, resulting in the derivative 2x+3.

6. Esdl

Esdl is used for embedded system modeling. Here’s an example of using Esdl to model a simple embedded system:

import esdl;

void main()
{
    // Define a simple system
    auto system = new System("LED Control");

    // Add components
    system.add(new Component("Sensor"));
    system.add(new Component("LED"));

    // Simulate system behavior
    system.run();
}

In this example, an embedded system with two components (“Sensor” and “LED”) is modeled using Esdl. The run() function simulates the system’s behavior.

7. DUnit

DUnit is used for unit testing in D. Below is an example of a simple unit test using DUnit:

import dunit;

void testAddition()
{
    assert(2 + 3 == 5);
}

void main()
{
    // Run the test
    runTests();
}

In this example, the test checks if the addition operation works correctly by asserting that 2+3=5. DUnit makes it easy to automate the execution of tests in D.

8. gtkD

gtkD is used for GUI development with the GTK+ toolkit. Here’s an example of creating a simple window with a button:

import gtkD.Gtk;

void main()
{
    // Initialize GTK
    Gtk.init();

    // Create a window
    auto window = new GtkWindow();
    window.setTitle("Hello, GTK!");
    window.setDefaultSize(300, 200);

    // Create a button
    auto button = new GtkButton("Click Me!");
    button.clicked.connect(() {
        writeln("Button clicked!");
    });

    // Add button to window
    window.add(button);

    // Show the window
    window.showAll();

    // Start the GTK main loop
    Gtk.main();
}

In this example, gtkD is used to create a simple GUI window with a button. When the button is clicked, it prints “Button clicked!” to the console.
