I'm not sure if this particular tool makes use of it but saws uses the python-prompt-toolkit - https://github.com/jonathanslenders/python-prompt-toolkit

Indeed it does, https://github.com/awslabs/aws-shell/blob/master/setup.py#L1...

Python Prompt Toolkit is pretty stellar, enough so to motivated writing a command line interface in Python instead of another language in my opinion.

Can't find anything in a search, is there something similar for ruby?

Awesome, that's exactly what I was looking for, thanks so much!
