Add this line to your application's Gemfile:

gem 'progress-bar'

And then execute:

$ bundle

Or install it yourself as:

$ gem install progress-bar


There exist three different handlers for ProgressBar: ProgressBar::KDE, ProgressBar::KDialog and ProgressBar::Console. These can be used directly, or you can use to determine the best solution.

If the process runs in a terminal, the ProgressBar::Console would be the best solution. If you run KDE, ProgressBar::KDE, which uses JobViewer via DBUS, would be nice. Else ProgressBar::KDialog will be tried. Other handlers could be added in future.

pb = 100, 'Initialization...'  # You expect 100 units (eg. percent)
pb.i += 5                                      # 5 units done! 5                                      # additional 5 units done
pb.text = "Working..."
pb.i += 80
pb.text = "Last steps"
pb.i += 10
pb.text = "Done!"
