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,

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
