Ruby循环直到出现问题

Question

对原始问题进行重新验证。我需要一个以ruby运行的循环，并允许我将命令停止输入到控制台（使用gets可能），然后循环停止。

干杯 马丁

我想你可以使用这样的事情：

# Initialize the input queue. This is where the user-created info will be stored 
$QUEUE = [] 
def pending 
    old = $QUEUE 
    $QUEUE = [] 
    old 
end 

t = Thread.new do 
    loop do 
    # Ask the user for something 
    print "Enter info here: " 
    # Read information in 
    $QUEUE << gets.chomp 
    end 
end 

# Example code utilizing this; you can do whatever you like with the queue 
2.times do 
    sleep 5 
    # Print the list out 
    puts "\nYou entered: \n" << pending.join("\n") 
end
