重新打开Ruby脚本

Question

I would like to re-open my script at the end of its execution. I tried with load but it didn't work. Is what I want to do possible? If yes, what should I try?

This is the structure of my script:

usr_choice = gets.chomp.to_i 
case usr_choice 
  when 1 
   # Do something
  when 2 
   # Do something else
  else 
   puts "Choice not recognised"
end 

Basically I would like for example to go back to the user input ( usr_choice ) after going through the case statement. Without a GoTo.

Answer 1

So you want a loop? Well, use loop :

loop do
  usr_choice = gets.chomp.to_i

  case usr_choice
  when 1
    puts 'one'
  when 2 
    puts 'two'
  else
    break # exit the loop (not the case construct as in other languages)
  end
end

Example:

$ ruby filename.rb
1
one
2
two
1
one
