force output during long process

[bwv549]

I'm running a long process and need to give some feedback to the user
(command line program). Is there some way to force output at a given
step of execution? Many times it seems that the output is spooled and
then printed to the screen all at once.

e.g.:

# ... inside some_very_long_program
puts "working..." # needs to display here and not spool it until
later

Thanks

To flush the buffer, use $stdout.flush
To not use a buffer at all, use $stdout.sync = true
