Features

xtd libraries architecture

architecture_logo

xtd is composed of several libraries.

xtd.core

core The xtd.core library is modern C++17/20 libraries of classes, interfaces, and value types that provide access to system functionality. It is the foundation on which c++ applications, components, and controls are built.

xtd.drawing

drawing The xtd.drawing library contains types that support basic GDI+ graphics functionality. Child namespaces support advanced two-dimensional and vector graphics functionality, advanced imaging functionality, and print-related and typographical services. A child namespace also contains types that extend design-time user-interface logic and drawing.

xtd.forms

forms The xtd.forms library contains classes for creating Windows-based applications that take full advantage of the rich user interface features available in the Microsoft Windows, Apple macOS and linux base operating system.

xtd.tunit

tunit The xtd.tunit library is a unit-testing framework for modern C++17/20, inspired by Microsoft.VisualStudio.TestTools.Cpp.

Development status

Current release status

GitHub milestone GitHub milestone

This project is an open source project. The developers who participate do so on their own time. It is therefore difficult to fix realese dates.

But you can follow the evolution of the development. We keep the status up to date.

Continuous Integration build status

At each commit, a build and unit tests are performed for the following configurations :

Examples

The classic first application 'Hello World'.

Console (CLI)

hello_world_console.cpp

#include <xtd/xtd>

using namespace xtd;

auto main() -> int {
  console::background_color(console_color::blue);
  console::foreground_color(console_color::white);
  console::write_line("Hello, World!");
}

or simply

#include <xtd/xtd>

using namespace xtd;

auto main() -> int {
  console::out << background_color(console_color::blue) << foreground_color(console_color::white) << "Hello, World!" << environment::new_line;
}

CMakeLists.txt

cmake_minimum_required(VERSION 3.20)

project(hello_world_console)
find_package(xtd REQUIRED)
add_sources(hello_world_console.cpp)
target_type(CONSOLE_APPLICATION)

Build and run

Open "Command Prompt" or "Terminal". Navigate to the folder that contains the project and type the following:

xtdc run

Forms (GUI like WinForms)

hello_world_forms.cpp

#include <xtd/xtd>

using namespace xtd::forms;

class main_form : public form {
public:
  main_form() {
    text("Hello world (message_box)");

    button1.location({10, 10});
    button1.parent(*this);
    button1.text("&Click me");
    button1.click += [] {
      message_box::show("Hello, World!");
    };
  }
  
private:
  button button1;
};

auto main() -> int {
  application::run(main_form {});
}

or simply

#include <xtd/xtd>

auto main() -> int {
  auto main_form = xtd::forms::form::create("Hello world (message_box)");
  auto button1 = xtd::forms::button::create(main_form, "&Click me", {10, 10});
  button1.click += [] {xtd::forms::message_box::show("Hello, World!");};
  xtd::forms::application::run(main_form);
}

tunit (Unit tests like Microsoft Unit Testing Framework)

hello_world_test.cpp

#include <xtd/xtd>

using namespace xtd;
using namespace xtd::tunit;

namespace unit_tests {
  class test_class_(hello_world_test) {
    void test_method_(create_string_from_literal) {
      auto s = string {"Hello, World!"};
      valid::are_equal(13, s.size());
      assert::are_equal("Hello, World!", s);
    }
    
    void test_method_(create_string_from_chars) {
      auto s = string {'H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!'};
      valid::are_equal(13, s.size());
      string_assert::starts_with("Hello,", s);
      string_assert::ends_with(" World!", s);
    }
  };
}

auto main() -> int {
  return console_unit_test().run();
}

or without helpers

#include <xtd/xtd>

using namespace xtd;
using namespace xtd::tunit;

namespace unit_tests {
  class hello_world_test;
  
  auto hello_world_test_class_attr = test_class_attribute<hello_world_test> {"unit_tests::hello_world_test"};
  class hello_world_test : public test_class {
    test_method_attribute create_string_from_literal_attr {"create_string_from_literal", *this, &hello_world_test::create_string_from_literal};
    void create_string_from_literal() {
      auto s = string {"Hello, World!"};
      valid::are_equal(13, s.size());
      assert::are_equal("Hello, World!", s);
    }
    
    test_method_attribute create_string_from_chars_attr {"create_string_from_chars", *this, &hello_world_test::create_string_from_chars};
    void create_string_from_chars() {
      auto s = string {'H', 'e', 'l', 'l', 'o', ',', ' ', 'W', 'o', 'r', 'l', 'd', '!'};
      valid::are_equal(13, s.size());
      string_assert::starts_with("Hello,", s);
      string_assert::ends_with(" World!", s);
