ASCII Menu in Ruby, is it possible?

Hello Team,

Is there a way in Ruby to create primitive ASCII menus?
At this point I am shying away from GUI as everything outthere, in the GUI
world is too....
I just want to know if I can create simple menus of the type:

1 - Enter 1 and press Enter to continue
2 - Enter 2 or X and press Enter to exit
3 - Etc.

Thank you

Did you try anything or just jump straight here to ask?

puts "1. Do something here"
puts "2. I want this"
puts "3. Hmm"

x = gets

case x
when "1"
  ...
when "2"
  ...
when "3"
  ...
end

Unless you're not including enough detail for a proper answer, a quick
jaunt through any Ruby book/tutorial/website would get you at least
this far.

Sure you can.

For example:

def menu
    loop do
        puts "1. Do something", "2. Do something else", "3. Nevermind"

        input = gets.strip

        case input
        when "1"
            puts "Did something"
        when "2"
            puts "Did something else"
        when "3"
            puts "Bye!"
            return else puts "Invalid option: #{input}"
        end end
end

You can find an example of doing this with the termios library by following the link in my sig and reading the Camping presentation. For more advanced text-based GUIs you could look at ncurses and highline.

Highline can build these menus for you. See examples here:

Dear Jason,

YES, I did first performed a google search, which is this:

"ruby" "menu" "ASCII menu"

and the above gave me this:
http://www.google.com/search?hl=en&q="ruby"+"menu"+"ASCII+menu"&start=30&sa=N

As a routine, I religiously perform first a good search. I also traverse the
gems repository. Then I come to the forum.
That been said, I appreciate your answer and justin answer. I truly
appreciate your help.
It was far from my mind using gets to perform this task.

Again, thank you!

Sure you can.

For example:

def menu
  loop do
      puts "1. Do something", "2. Do something else", "3. Nevermind"

      input = gets.strip

      case input
      when "1"
          puts "Did something"
      when "2"
          puts "Did something else"
      when "3"
          puts "Bye!"
          return else puts "Invalid option: #{input}"
      end end
end

If you are planning to do some data entry checking on Linux platforms
you may need to set the STDOUT.sync = true. I am including a simple
program to show you the difference. Indeed on MS Windows you will not
experience any difference if you comment out "STDOUT.sync = true"; on
Linux if buffering is turned on you will!

STDOUT.sync = true

#!/usr/bin/env ruby

STDOUT.sync = true # (cross-platform compatibility issue)

loop do
  print "\n\n\tPLEASE SELECT:\n\n"
  print "\t\t(1) ..... enter one number\n"
  print "\t\t(2) ..... enter two numbers "
  print "(no seoarators like commas, ...)\n"
  print "\t\t(Q) ..... Quit\n\n"
  print "\tPlease select one of the above: "
  answer = gets
  printf "You've selected %s\n", answer

  case answer.chomp
  when "1"
    num = nil
    while num !~ /\d+.*[^\d]*/
      print "Please enter a single number: "
      num = gets
      num.chomp! # note exclamation mark (!)
      if num.split(/\s+/).size != 1|| num !~ /\d+/
        puts "You should have entered a single number not [#{num}]"
        print "Press <Enter> to continue "
        any = gets
      else
        puts "Thank you for [#{num}]."
      end
    end
  when "2"
    num = nil
    while num !~ /\d+[\s,]+\d+/
      print "Please enter two numbers: "
      num = gets
      num.chomp! # note exclamation mark (!)
      if num.split(/\s+/).size != 2 || num !~ /\d+\s+\d+/
        puts "You must enter two numbers number, not [#{num}]"
        print "Press <Enter> to continue "
        any = gets
      else
        puts "Thank you for [#{num}]."
      end
    end
  when /q|Q/
    exit
  else
    print "Illegal selection; Please try again! "
    print "Please enter a single number:\n"
    print "Press <Enter> to continue "
    any = gets
  end
end
