Hi

Does anyone have some examples of making a client socket 
connection to a host on a port and parsing the incoming data in 
some kind of loop.

I put one in chapter 2 of my book:
https://www.packtpub.com/application-development/d-cookbook

Here's the code sample alone:
http://arsdnet.net/dcode/book/chapter_02/03/

The client just takes lines from the user and forwards them to 
the server. Not really useful alone but maybe it will show you 
how to get started. The text in the book itself goes into a 
little more detail and you can look up the functions here 
http://dlang.org/phobos/std_socket.html for a lil more info.

Great thanks.

How would I send stuff back to the server without blocking? Is 
there some kind of IO reactor / event machine library for D that 
could help me?

you could also just use Socket.select and not worry about the 
whole blocking thing as much then to handle multiple ones at once.

If you have like < 20 connections, select works really well and 
is easy.

Nanomsg might be one option if you control the host - by one of 
the main authors of Zeromq.  He decided to rewrite in C and it 
addresses some architectural flaws of Zeromq.  (At least one 
smart guy in London D community agrees it's better).

http://www.infoq.com/news/2012/03/Crossroads-IO
http://nanomsg.org/

Nanomsg itself is at an early stage, and I think the author has a 
lot on his plate (if I recall right he is now at Google) so 
progress isn't as fast as one would like.

But it's usable, and I have some primitive D bindings/wrapper 
here.  Nanomsg seems stable enough for me, and one or two 
glitches in bindings/wrappers but I am using them for my stuff.  
I know that if nanomsg ends up being a disaster I can always 
switch to zeromq, which is similar enough to do so easily.

D written for C style bindings for pipeline here:

int node0 (string xurl)
{
   int sock = nn_socket (AF_SP, NN_PULL);
   auto url=xurl.toStringz;
   assert(sock >= 0);
   assert(nn_bind (sock, url) >= 0);
   while (1)
     {
       char* buf = cast(char*)0;
       int bytes = nn_recv (sock, &buf, NN_MSG, 0);
       assert (bytes >= 0);
       writefln("NODE0: RECEIVED %s bytes: \"%s\"", 
bytes,to!string(buf));
       nn_freemsg (buf);
     }
     return 0;
}
