 chatroom server
 ----
 This program is totally written in lua.It shows all of these functions that server can support
 
 function|description
 --------| -----------
 multi-client|look at the pic(chatroom.png)
 broadcast|server send msg to all clients
 server disconnect client directly|look at the pic(chatroom.png)
 not just send one line a time|it is a really tcp server!you can do anything as a normal server do
 server kick clients when the program is done|nothing to explain
 
 How Does It Work
 ====
 ![](https://sourceforge.net/p/runasdog/screenshot/runasdog-how%20it%20works.png)
 
 1.dog create a child progress 'cat',cat where run the command from the arguments,like 'bash'.
 2.dog chat with cat by pipe A and pipe B.
 3.cat input stdout and stderr into pipe A,and read from pipe B.
 4.dog start a server,watch for clients join at server port
 5.dog redirect the message from client to pipe B,receive from pipe A,and redirect them to the client.

 ========
-If with '-s',The server runs simple ,just redirect the whole things.But when there are more than one clients join,server must be able to identify who is who there,and which words of the messages got from cat's stdout/stderr should send where. So,the mode without '-s' comes into being.

 =====
 1.Check out svn :svn checkout svn://svn.code.sf.net/p/runasdog/code/trunk runasdog-code
 or download release files above.
 2.cd runasdog-code,and make(be sure you have libevent-1.4 installed)
 3.run test***.sh files for testing.There are two samples,one is remove bash server,another is chatroom.
 4.run telnet 127.0.0.1 3000 for testing.

 What is different between '-s' and without?
 ========
 If with '-s',The server runs simple ,just redirect the whole things.But when there are more than one clients join,server must be able to identify who is who there,and which words of the messages got from cat's stdout/stderr should send where. So,the mode without '-s' comes into being.
 In this mode,cat recv buffers as this format:
 
 |
 -|-
 c5:127.0.0.1:1344|c:connected,5:client pipe id,127.0.0.1:1344 is the client address
 r5:7:hello u|r:received,5:client pipe id,7:content len,hello u:real content from client
 d5:|d:disconnected,5:client pipe id
 cat send buff as this format:
 
 |
 -|-
 5:7:abcdefg|5:client pipe id,7:content length,abcdefg:content for send to client
 -5:7:abcdefg|5:client pipe id,-5 means after send this content,server will close the client
 0:7:abcdefg|0:broadcast to all the clients
 
 In lua ,there is a demo to handle this:
 
     local function put(fd,...)
     	local s=table.concat({...},"\t").."\n"
     	local len=string.len(s)
     	local format=string.format("%d:%d:%s",fd,len,s)
     	io.stdout:write(format)
     	io.stdout:flush()
     end
     local function get(line)
-    	local t,fd,other=string.match(line,"([cdr])(%d+):(.*)")
-    	if t then
-    		fd=tonumber(fd)
-    		return t,fd,other
-    	else
-    		return nil,nil,nil
-    	end 
+    	local result=""
+    	local t,fd,count,other
+    	while true do
+    		t,fd,count,other=string.match(line,"([cdr])(%d+):(%d+):(.*)")
+    		if t then
+    			fd=tonumber(fd)
+    			count=tonumber(count)
+    			result=result..string.sub(other,1,count)
+    			line=string.sub(other,count+1,-1)
+    			if line=="" then
+    				break
+    			end
+    		else
+    			break
+    		end 
+    	end
+    	return t,fd,result
     end 
     
     local function onConnect(fd,addr,port)
