API translation project

The goal of this project is to translate existing APIs to D. Primary target is, of course, Win32 API, but there are others: OpenGL and ODBC, to name a few. Here's the list of APIs I've translated so far:

At the moment, I work on new Win32 translation. The one that is there had some bugs and inconsistences, simply because it was generated by an automatic translator. Now, the translator was rewritten, and generated code is manually corrected where necessary.

You can download the latest versions of API import modules from the files section.

Streams & sockets

Currently, D specification doesn't provide any way of more or less complicated generic and file I/O; streams are supposed to be extendable and portable way to do that. The module is completely object-oriented, with Stream as an abstract base class, defining the interface, and implementing functionality common to all kinds of streams. File is a practical Stream implementation, designed to perform binary input/output on disk files. Also, there is an in-memory Stream-based wrapper around OutBuffer.

While the library is already pretty usable, it is in constant development. For now, the goal is to add formatted text input/output to streams, something more clear and typesafe than printf. This probably has to wait till the language gains abilities to implement it, however, native (that is, written in D) versions of printf and scanf could be provided already. Making them understand D types not present in C, like dynamic char arrays, bits, complex and imaginary numbers, seems to be reason strong enough to rewrite from scratch completely rather than relying on C printf. In future, streams will also probably work together with D locales.

Socket library is separate from streams, however, there are obvious reasons to describe them together: TCP client sockets are best represented by streams. Module provides base classes ServerSocket and ClientSocket, their TCP implementations TCPServer and TCPSocket, DatagramSocket base class for datagram sockets, and derived UDPSocket implementation, as well as helper classes like IP and InternetAddress. Together, they form a powerful library, providing fast and easy access to TCP/IP sockets. The library is pretty much complete, but needs testing.

Older version of streams module is available in D distribution, but I strongly recommend to download the latest version from this site. You can download both modules, sockets and streams, from the file section.


WinD is a D user interface class library for Windows (hence the name). It is my primary project, and is being actively developed at the time. The main goal of the project is to make a set of classes that would make Windows GUI programming child's play - well, almost =). Approach is more VB/Delphi like, and if you've ever used these tools, you will notice many common things in WinD. On the contrary, it has almost nothing in common with MFC, don't expect to get another thin wrapper over the API. Here are the main guidelines of the project:

Here's a sample WinD program, which already compiles and runs successfully:

    import wind;
    class MyFrame: Frame
        Button OK, Cancel;
            caption("Hello, world!");
            with (OK = new Button(this))
            with (Cancel = new Button(this))
    	        top(OK.top() + OK.height() + 10);
        void OK_Click(Event e)
        void Cancel_Click(Event e)
            messageBox("Not so fast!");
    int main()
        MyFrame frame = new MyFrame;
        return 0;

As you can see, it is pretty straightforward. You create an object for each control, define their properties, bind event handlers to slots, and then just let it run. Class and function names are short and easy to remember, and you can easily write a program entirely in your text editor, without any form editors or wizards.

The library is in active development, and working version does already exist. It isn't quite ready for release yet, though, but expect to see the first alpha in a couple of days!
