arsd.com

Code for COM interop on Windows. You can use it to consume COM objects (including several objects from .net assemblies) and to create COM servers with a natural D interface.

This code is not well tested, don't rely on it yet. But even in its incomplete state it might help in some cases.

namespace Cool {
	public class Test {

		static void Main() {
			System.Console.WriteLine("hello!");
		}

		public int test() { return 4; }
		public int test2(int a) { return 10 + a; }
		public string hi(string s) { return "hello, " + s; }
	}
}

Compile it into a library like normal, then regasm it to register the assembly... then the following D code will work:

1 import arsd.com;
2 
3 interface CsharpTest {
4 	int test();
5 	int test2(int a);
6 	string hi(string s);
7 }
8 
9 void main() {
10 	auto obj = createComObject!CsharpTest("Cool.Test"); // early-bind dynamic version
11 	//auto obj = createComObject("Cool.Test"); // late-bind dynamic version
12 
13 	import std.stdio;
14 	writeln(obj.test()); // early-bind already knows the signature
15 	writeln(obj.test2(12));
16 	writeln(obj.hi("D"));
17 	//writeln(obj.test!int()); // late-bind needs help
18 	//writeln(obj.opDispatch!("test", int)());
19 }

I'll show a COM server example later. It is cool to call D objects from JScript and such.
