Καλό μήνα! A while back I wrote about how to overwrite console output in Ruby. Originally the project I used this technique for only required overwriting a single line of output. That project has now grown and I need to be able to maintain a mini-dashboard on the console.
Fortunately, Ruby rocks and has a standard library wrapper for Curses.
I would encourage you to read through the documentation. I’ve written a simple
script to show-off the most basic use-case. In this example I initialize ten
workers. Each worker is responsible for keeping track of the work she has
@percent, and then reporting that progress on her own line,
@index, of the console.
Because Curses clears the screen once it is complete, the
ensures that the last known state of the workers is echoed to the screen one
Another command I found useful was the
Curses.clear command. This function
clears the entire screen before rewriting output. This is particularly helpful
when you want to overwrite a long line of text with a shorter one.
I hope this was helpful! Have fun making some cool console applications. If you build something worth sharing, please leave a comment that links to your code.
