Note: This is a WIP project.

Provides D bindings to NAppGUI.

NAppGUI is a professional SDK to build cross-platform desktop applications using The C Programming Language (ANSI C90). NAppGUI has built as a lightweight layer on top of the operating system native APIs, that allows create portable programs extremelly fast and small without any external dependency.

Compatible with @nogc, nothrow and BetterC. Requires static linking with NAppGUI libraries.

Windows

Using NAppGUI on Windows currently requires Visual Studio. When using debug libraries, make sure to pass -mscrtlib=libcmtd to compiler. To hide Command Prompt window, use "/SUBSYSTEM:windows" and "/ENTRY:wmainCRTStartup" linker options.
