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?

Adam


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.
