server/client connection  
so, im only a few days into ruby, im working on some tcp and there is a  
problem with my client.rb… if str == ??? this if statement is always  
skipped and im not sure why?

also, from the server with the gets command i want to send the client a  
string like “mike skateboard boxing” then when the client recives this  
string how can i brake this into 3 arrays or strings?

#server.rb  
require “socket”  
dts = TCPServer.new(‘localhost’, 1234)  
loop do  
Thread.start(dts.accept) do |s|  
print(s, " is accepted\n")  
#gets, what command to send to the client?  
str = gets  
s.write(str)  
print(s, " is gone\n")  
s.close  
end  
end  
------------end of server-------------

#client.rb  
require ‘socket’  
while true  
streamSock = TCPSocket.new( “127.0.0.1”, 1234 )  
str = streamSock.recv( 100 )  
print str

if str == ‘mike’  
print ‘Hi mike’  
elsif str == ‘user’  
print ‘hi user’  
end  
end

--------end of client

#gets method returns a string with a newline if you ended the  
input with enter. You can chomp it or use double Ctrl-D  
instead of enter.

I’ve gotten into the habit of using gets.chomp when reading input of  
any kind. It’s so easy to forget that newlines are still on there.

Oh, wow… a bit confused at first but then i googled ruby chomp and  
then it made sence, when you press enter \n

if string.chomp == “mike”  
print “hello mike\n”  
system(“calc.exe”)

# how can i execute calc.exe and continue with the script well calc is

still running???
