Subject: Re: timeout question

Hi,

I ran the script(script a) in irb mode and I find it never jumps to next 
element without input from outside/console, which is not what I want. 
Here is my requirement for the timeout: 1) iterate an array 2)when 
jumping from one element to the next wait for 5 seconds for the input. 
If no input after 5 seconds then jump to the next element. If there is 
an input then process the input. After that also jump to the next 
element.

Also I ran two very short scripts (script b and script c) after reading 
doc for Timeout. I find that one works and other doesn't work: without 
input from the console the timeout does not work.

Any idea?

Thanks,

Li




####script a: without input the array never move forward ####

###script b doesn't work#####

C:\Users\Alex>irb
irb(main):001:0> require 'timeout'
=> false
irb(main):002:0> Timeout.timeout(10){gets}



###script c works by raising an error###

C:\Users\Alex>irb
irb(main):001:0> require 'timeout'
=> false
irb(main):002:0>
