Is there a command line framework for ruby? [closed]

Question

So, there are web frameworks, there are GUI frameworks, I was just wondering if there was a console/command line framework for ruby?

Specifically, I would like to be able to:

1. Have a particular view wherein I could tab to different input segments. Exactly like you can do with forms on a web page.
2. I would like the usual console shortcuts to work (ctr-k, ctr-a, ctr-e, etc)
3. If the cursor is at a certain input position, sometimes I would like it to response to a single key press event, rather than my having to enter text and then press enter.

Does not have to be a unified framework. But I notice that it does seem somewhat cumbersome to write console apps in ruby. Are there any tools that make this easier?

Answer 1

Judging from your questions it sounds like your like looking for curses-based frameworks. But in case that you're not, here are some console/irb-related gems I've written that may be useful:

• hirb - view framework for associating classes with views
• bond - custom readline completion made easy
• boson - console command framework

Now to answer your questions:

1. Though I don't know how to do it, there is this nice curses app whose source code you could read.
2. require 'readline' gives you those keybindings
3. require 'highline'; answer = HighLine.new.ask('ask something') {|e| e.character = true }
