xtd libraries architecture


xtd is composed of several libraries.

xtd.core
The xtd.core library is modern c++17/20 library 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
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
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 operating system.

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

Objectives and Mission

• xtd is a powerful, yet easy to use platform to build your applications upon.
• xtd is modular and scalable from embedded applications.
• xtd provides consistent, comprehensive and comprehensible programming interfaces.
• xtd favors simplicity over complexity ("as simple as possible, but not simpler").
• xtd aims for consistency in design, coding style and documentation.
• xtd emphasizes source code quality, in terms of readability, comprehensiveness, consistency, style and testability.
• xtd aims to make C++ programming fun again Guiding Principles
• Strong focus on code quality, style, consistency and code readability – all code must satisfy our coding style guide.
• Strong focus on tests (automated unit tests with high coverage).
• Build on top of solid foundations – use existing proven C, C++ or Objective-C libraries (e.g. Win32 APi, Gtk4, AppKit,...) where it makes sense.
