D Text User Interface library

This library implements a text-based windowing system loosely reminiscient of Borland's Turbo Vision library. For those wishing to use the actual C++ Turbo Vision library, see Sergio Sigala's updated version that runs on many more platforms.

Three platforms are available:

• Posix under an X11 terminal (tested on Linux + xterm). Input/output is handled through terminal escape sequences generated by the library itself: ncurses is not required or linked to. xterm mouse tracking using UTF8 coordinates is supported.

• Windows console mode (tested on Windows XP). Input/output is handled via Win32 console functions.

• As an X11-style terminal communicating over a non-blocking socket.

Contributions towards supporting other platforms would be greatly appreciated.

License

This library is licensed LGPL ("GNU Lesser General Public License") version 3 or greater. See the file COPYING for the full license text, which includes both the GPL v3 and the LGPL supplemental terms.

Usage

The library is currently under initial development, usage patterns are still being worked on. Generally the goal will be to build applications somewhat as follows:

import tui;

public class MyApplication : TApplication {

    this() {
        super();

        // Create an editor window that has support for
        // copy/paste, search text, arrow keys, horizontal
        // and vertical scrollbar, etc.
        addEditor();

        // Create standard menus for File and Window
        addFileMenu();
        addWindowMenu();
    }
}

void main(string [] args) {
    MyApplication app = new MyApplication();
    app.run();
}

See the file demo1.d for many example usages.

Acknowledgements

Thanks go out to Adam Ruppe for his terminal.d class which greatly accelerated support for the Win32 console.
