Hi Friends,

Socket programming with the D programming language is the most 
simple way how to do it

For example, the sample with Tango, but not by phobos

How do I do this with a simple, but phobos


import tango.io.Stdout;

import tango.net.Socket;
import tango.net.ServerSocket;
import tango.net.SocketConduit;

int main() {
     Socket server = new Socket(AddressFamily.UNIX,
                                SocketType.STREAM,
                                ProtocolType.IP);

     while(true) {
         Socket client = server.accept();

         char[1024] buffer;
         client.receive(buffer);

         Stdout.format("The client said'{}'.", buffer);

         client.shutdown(SocketShutdown.BOTH);
         client.detach();
     }
     return 0;
}

Here is a Phobos translation: import std.stdio; import std.socket; void main() { Socket server = new TcpSocket(); server.setOption(SocketOptionLevel.SOCKET, SocketOption.REUSEADDR, true); server.bind(new InternetAddress(8080)); server.listen(1); while(true) { Socket client = server.accept(); char[1024] buffer; auto received = client.receive(buffer); writefln("The client said:\n%s", buffer[0.. received]); enum header = "HTTP/1.0 200 OK\nContent-Type: text/html; charset=utf-8\n\n"; string response = header ~ "Hello World!\n"; client.send(response); client.shutdown(SocketShutdown.BOTH); client.close(); } } Ali P.S. Note that there is also the D.learn newsgroup. P.P.S.

Not quite the same - the original used a Unix domain socket. I *think* if you replace that line with a UnixAddress: http://dlang.org/phobos/std_socket.html#UnixAddress It will do the trick. (I say *think* because I've never actually used a unix socket with D, so I'm not entirely sure.)

http://d.puremagic.com/issues/show_bug.cgi?id=9384 It won't work. (This is why my project uses IP sockets for local communication, even on Linux)

Meaning that domain/Unix sockets aren't available at all in D (or need to be done through C calls directly)?

Thanks acehreli In the example you give, but I receive this error during compilation. savsak:~ savsak$ dmd /Users/savsak/Desktop/test.d ld: library not found for -lphobos2 collect2: ld returned 1 exit status --- errorlevel 1

That has already been fixed in the version of Phobos on Github (I've marked it as fixed now, didn't know about that issue on bugzilla before).

Your dmd installation is broken. Please tell how have you set it up to get any fixing suggestions ;)

To help dicebot and others to help you it would be useful to copy the output of the following two commands:
 cat /etc/dmd.conf

 find /usr -name 'libphobos2*'

(Please note the *single* ticks (rather than ") to not have your shell resolve it. Also note that probably /usr/lib would be more efficient as search path but using /usr can also catch exotic cases like /usr/share). If your installation is OK you will find the paths told by the find command to match those in /etc/dmd.conf. Here is an example of a working installation: $ find /usr -name 'libphobos2*' /usr/lib/x86_64-linux-gnu/libphobos2.so /usr/lib/x86_64-linux-gnu/libphobos2.a /usr/lib/i386-linux-gnu/libphobos2.so /usr/lib/i386-linux-gnu/libphobos2.a /usr/lib/i386-linux-gnu/libphobos2.so.0.2 --------------- $ cat /etc/dmd.conf // ... some comment lines ..
