Attaching a script to IO

Ari Brown

7/24/2007 6:48:00 PM

Hey all,
I'm trying to attach a script's output to IO (a socket. Is IO
the right term?)
I currently use a GServer script to accept connections from localhost.

I don't know if that made sense, but is there any way to change the
default output to my socket output?

Thanks,

Oh, and if it makes a difference, information on using sockets with
Highline (Thanks, james!) would be GREATLY appreciated.

Works for me!

Well, can you just send whatever you need to send via puts?

Example:

class MyThingy < GServer
def initialize(port=3000, *args)
super(port, *args)
end
def serve(io)
io.puts "Hello!"
end
end

Well, except I'm not trying to send "hello". I'm trying to keep my
script nice and clean, so I have a bunch of ugly code in a separate
file (which I call with require) and a method test(). If I pass io
as an argument with test:

def serve(io)
test(io)
end

and then later in test(io) have

io.puts

will the variable scope allow that?

Or should I find a way to reroute $stdout?

thanks,
ari

It seems you want your script to act as a _server_. In that case class
TCPServer will help you. Please have a look:

Kind regards
