Ruby require_relative executing script? - ruby

Question

I'm working on a game server in ruby, and during testing I'm having trouble testing components individually. I wasn't getting output from my launcher, just the server, so I commented out the initialisation of the server- yet eclipse still showed output from the server!
I then went to the command line, assuming eclipse was looking at the wrong file (git has messed it around before, but as you can see, the stack trace shows that Server.rb is being executed in its entirety from line 5: require_relative 'Server':
This is the text content of the file:
class Launcher
puts "File saved at #{File.mtime($0)}"
require_relative 'Server'
require_relative 'Game'
#STDOUT.sync = true
puts "Launcher started"
#server = Server.new
print "server made"
game = Game.new
#serverThread = Thread.new{server.start()}
gameThread = Thread.new{game.start()}
while (running)
print "Stop? "
input = gets.chomp
if (input.equals?("yes"))
running = false
end
end
server.stop
game.stop
gameThread.join
serverThread.join
end
and the terminal output:
C:\Users\gossfunkel\git\citadelserver\RubyCitadelServer>ruby Launcher.rb

from Launcher.rb:5:in `<class:Launcher>'
from Launcher.rb:1:in `<main>'
How do I require a file without this happening, and should it be?

Answer 1

I can't tell without seeing the classes, but I would guess that either
game.start is doing more than you thought, and is starting the server for itself
You are, as your subject line suggests, running a different file from the one you are editing (or not saving the file once it is changed). Check by putting an obvious puts at the top of the program. Something like
puts "File saved at #{File.mtime($0)}"
should do the trick
After discussion, it seems there's a third option. The code in Server.pm creates and runs a server as well as defining the class. You need to remove the require as well as the lines that use the Server class.
