Guys -
I'm working on a simple Chat Server/Client just to become familiar with
ruby socket programming. I've put together this very simple server that
accepts a connect and prints out the first message received. I've done
this in Java as well, but the issue I'm finding here is I cannot ctrl+c
to quit the server. Do I need to create a thread to listen for keyboard
input and then pass this to a quit method? It seems to me that ctrl+c
(or ctrl+z depending on os) should always force quite a running program,
right? In this case, it's just hanging. Any help appreciated.

require 'socket'
class ChatServer
def initialize(port)
@port = port
end
def run_server
@sessions = {}
@my_server = TCPServer.new('localhost',@port)
puts "Server running...."
while(session = @my_server.accept)
@action = session.gets
puts @action
end
@my_server.close
end
end
my_server = ChatServer.new((ARGV[0] || 80).to_i)
my_server.run_server

You didn't say what platform you're running on. It works for me, using Linux
(Ubuntu 6.06):
$ ruby1.8 ert.rb 9999
Server running....
flurble << this sent from a client
ert.rb:16:in `accept': Interrupt
from ert.rb:16:in `run_server'
from ert.rb:27
If you are running Windoze, then I expect it's blocking inside one of the
socket calls.
BTW there is a fuller server example, which handles each incoming connection
in its own thread, at

I am running Windows (at work, mac at home) but I thought ruby's thread
were "cross platform" as there were implemented purely in ruby. I even
added a thread to handle keyboard input in the on the server and it's
still locking on my box. I see the output:
Server running...
Press any key to quit...
But nothing I press unlocks it. Am I doing something wrong here (revised
code below)?
require 'socket'
class ChatServer
def initialize(port)
@port = port
@sessions = {}
end
def run_server
@my_server = TCPServer.new('localhost',@port)
Thread.new(self){|server| InputHandler.new(server).run}
while(session = @my_server.accept)
puts session.gets
session.close
end
end
def quit
@my_server.close
exit
end
end
class InputHandler
def initialize(server)
@server = server
puts "Server running..."
end
def run
puts "Press any key to quit..."
gets
server.quit
end
end
my_server = ChatServer.new((ARGV[0] || 80).to_i)
my_server.run_server
