How to fix this error message? syntax error, unexpected tIVAR - ruby

Question

I'm trying to run some tests on my code, but I'm running into a problem. For a very simple line of code, I get a weird error message. This test is to make sure my server can receive info from one of my clients.
The tests and file run fine without this line:
client_1.#socket.puts("This gives an error.")
Including that bit of code gives this error:
macowner:WAR3 macowner$ ruby ServerTests1.rb
ServerTests1.rb:160: syntax error, unexpected tIVAR, expecting '('
client_1.#socket.puts("Output for Server to receive.") #Error
^
Help is greatly appreciated. I get this error fairly frequently, but I have no idea what it means (even with searching for it).

Answer 1

If you're trying to access the #socket instance variable then you just need another accessor method in MockWarClient:
def socket
#socket
end
and the say client_1.socket.puts(...) to use it. You could also use attr_reader to simplify things:
class MockWarClient
attr_reader :socket, :input, :output
def initialize
#socket = TCPSocket.new('localhost', 2012)
end
def capture_output #need to add (socket)? How else read from specific socket?
#output = #socket.read_nonblock(1000) # arbitrary max number of bytes
rescue
#output = "capture_output error."
end
def write_input
#input = #war_server.client_keys.write_nonblock(1000)
end
end
That will create the three accessor methods for you.

Answer 2

You cannot call a method named #socket in a usual way as you are trying in client_1.#socket. That method name is very unusual because it is confusing with an instance variable, and it is doubtful that you actually have such method, but if you do, then the way to call such method is:
client_1.send(:#socket)
