Breaking from a definition one level up

In the code below, break exits the program totally and returns to irb, while I want to get back to the line where the print statement is.

def f1()
  do_something
end

def f2()
  do_something
end

def f1()
  print "I want to get back here."
  while true
    choice = gets.chomp
    if choice == "exit"
      break
    else
      f2()
    end
  end
end

How do you break just one level up?

Solution

  • Add another loop outside. It may also be simpler to use loop than while true:

    def f1()
  loop do
    print "I want to get back here."
    loop do
      choice = gets.chomp
      if choice == "exit"
        break
      else
        f2()
      end
    end
  end
end
