Sleep

This program is very simple. It is suppose to load in the text file, load
each character into an array, then print out the array one letter at a
time. It is supposed to wait 1 second each time it prints. This freezes
every time I run it. Any ideas?

class Slow_Array

    def array_split
        @f = File.open('Text_for_TextReader.txt','r') do |f|
            f.gets.scan(/\w/)
        end
    end

    def print_and_wait
        @f.each {
            >i>
            print i
            sleep 1
        }
    end

end

#-------------------------------------------------
# Main logic
TextReader = Slow_Array.new

# Bring file into program
TextReader.array_split

# Print each character, waiting one second in between each printing
TextReader.print_and_wait

It doesn't freeze, but the output is buffered so it appears that way. try adding a flush:

   print i
   STDOUT.flush
   sleep 1

You can either:

$stdout.sync = true

or:

class SlowArray
  def slow_each
    File.open('Text_for_TextReader.txt') do |file|
      while line = file.gets
        puts line
        sleep 1
      end
  end
end

SlowArray.new.slow_each

STDOUT.flush
Did exactly what I wanted and it was an easy fix. I would have never
figured that out. Thank you.
