A Ruby terminal progress_bar

ProgressBar is a simple Ruby library for displaying progress of long-running tasks on the console. It is intended to be as simple to use as possible.NOTE: This project isn't dead! It's just feature complete, and I don't want to keep adding things to it. If you find bugs, please open an Issue, or even better, a Pull Request, and I'll take a look. We at ProgressBar know you have lots of progress bar alternatives, and we thank you for using ProgressBar!.
