Ruby Dialog Interface

→ ‘rdialog’

What

Interface with the command-line curses interface dialog, and rapidly develop simple dialog-driven TUI applications

Installing

Install dialog on your machine.

sudo gem install rdialog

The basics

After installation is complete, require the gem in your source code, and away you go!

RDialog handles the interface between ruby scripts and dialog’s command-line interface. RDialog accepts input as arrays and/or strings, and returns similar objects.

Once you have initialized an instance of RDialog via

RDialog.new

, options can be set that will persist throughout the lifetime of the instace. For example:

dialog = RDialog.new
dialog.shadow = false

This will prevent dialog from drawing shadows around all further boxes.

Demonstration of usage

require "rdialog" 

items = Array.new
items.push(["softcheese.net", "a cool server", false])
items.push(["filter.eu.org", "an even cooler server!", false])
items.push(["oink.me.uk", "quite cool as well", true])

dialog = RDialog.new

dialog.nocancel = true
selected_item = dialog.radiolist("ssh to:", items)

exec("ssh sweeper@" + selected_item)
