xtd_c (pronounced "extend for c") is a C11 framework to create console (CLI), forms (GUI like WinForms) and tunit (unit tests like Microsoft Unit Testing Framework) applications on Microsoft Windows, Apple macOS, Linux, iOS and android (*).

(*) See portability for more information.

⚠️ xtd_c IS UNDER DEVELOPMENT AND IS NOT READY TO BE USED. ⚠️

• Free and open-source (MIT License);
• a collection of native C11 libraries, to extend C11 standard;
• API close to the xtd with a modern C11 approach and full integration with the ANSI/ISO standard;
• xtd_c is designed to manage GUI controls and dialogs in pure native mode or with CSS styles.
• written in efficient, C11;
• and highly portable and available on many different platforms;

xtd_c is a C11 wrapper on xtd framework. You need to install xtd before using xtd_c.

xtd_c is composed of several libraries.

The xtd_c.core library is C11 libraries of struct, enum, and value types that provide access to system functionality. It is the foundation on which C11 applications, components, and controls are built.

The xtd_c.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.

The xtd_c.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.

The xtd_c.tunit library is a unit-testing framework for modern C11, inspired by Microsoft.VisualStudio.TestTools.Cpp.
