Hello

Im trying to execute commands on server side. Here is my server 
based on other example from forum:



import std.stdio;
import std.socket;
import std.algorithm;
import std.conv;

void main() {
     Socket server = new TcpSocket();
     server.setOption(SocketOptionLevel.SOCKET, 
SocketOption.REUSEADDR, true);
     server.bind(new InternetAddress(8080));
     server.listen(1);


	Socket client = server.accept();

     while(true) {


         char[1024] buffer = 0;
         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);
	

	if(to!string(buffer) == "exit")
	{
		
		break;
	}
    }

     client.shutdown(SocketShutdown.BOTH);
     client.close();

}

When i send "exit" nothing is happening. How it should be done to 
make it working?

I changed my condition to:

if(to!string(buffer[0..received]) == "exit")
	{
		
		break;
	}


But it still dint help.

The client probably sends a newline; i.e. buffer[0 .. received] is "exit\n".

Or more likely it's "exit\r\n".

I changed condition to:

	{

and now it is working. Thank you all for help.

You shouldn't need that to!string by the way. I believe that will 
work just comparing the buffer directly.

Converting to string is more important when you are storing a 
copy than just comparing it.
