Hello,
I have a little script that processes excel file and I would like the
script to output some sort of status either line or percent number as it
runs.
How can I output something to console always in the same spot, meaning
that I don’t want start new line every time the script advances.
Something like this:
Progress: 51% - I want this number to change and stay in the same spot.

Perhaps the following example will help you. Please note the \r at
the beginning of the format strings.
0.step(100, 10) do |i|
printf((i < 100 ? "\rProgress: %02d\%" : "\rProgress: %3d\%"), i)
$stdout.flush
sleep(1)
end
puts

This is exactly what I was looking for.
Thanks.

The backslash before % is meaningless and just ignored. You
need two %'s to print one %.

You are of course right: the backslash before the percent should be
another percent. But in this case doubling the percent also turns out
to be unnecessary. The following works (in Ruby 1.8.2) although one
would think that it wouldn’t:
0.step(100, 10) do |i|
printf((i < 100 ? "\rProgress: %02d%" : "\rProgress: %3d%"), i)
$stdout.flush
sleep(1)
end
puts
It seems to work because the single percent occurs at the end of the
format string. Is this a minor bug in printf? Is it behavior
inherited from C?

for i in 1…10 do
print “Progress #{i}% is done.\r”
sleep 1
