Add Jline option to do list view of autocomplete suggestions

[parrotcar00]

I just saw Python prompt toolkit: https://github.com/prompt-toolkit/python-prompt-toolkit which does a list view of autocomplete suggestions and was wondering if I could do something similar with Jline? I was looking for a Java library instead of a python one to do this.

Yes, you can do something similar using TailTipWidgets.

There is a test implementation you can play with Console and a couple of demo apps to start from

1. Groovy REPL
   Uses JLineCommandRegistry. You can create commands that have Object parameters and returns Object and you can use scripts within your app. Wiki pages: Groovy language REPL, REPL Console and REPL Console Customization. Updated asciinema demo.
2. Graal
   Uses JLineCommandRegistry. No Groovy nor console scripts and variables.
3. Picocli

If a list view of suggestions you mean a list below the field to be completed like in figure below then the answer is no.

Added JLine option AUTO_MENU_LIST to show suggestions below the field to be completed. Menu colours can be customised using JLine variables COMPLETION_COLOR_STARTING, COMPLETION_COLOR_DESCRIPTION and COMPLETION_LIST_BACKGROUND_COLOR
