Actually I can’t understand what the cause of my problem is, I start the loop , everything works correctly, a certain list is displayed in the terminal, but as soon as I get it into the method, everything ends there, there are no errors when starting, but there is no list from the cycle loop , tell me where to dig?

An example that works:

 loop do puts "Hello World" break end

An example of what doesn't work, but needs to be done:

  def menu loop do puts %Q( 1. Посчитать цену молока ) puts "Введите нужное число из меню:" input = gets.chomp case input when 1 show_moloko end end end def show_moloko тут вычисляем end

  • No, well, so it became much better, it was immediately clear what was the matter. - Igor
  • @Igor Dovabil for clarity, a couple of examples. - Denis T. Nov.
  • Do you call the menu function? - Igor
  • @Igor I understand where you're going, no, I don’t call, the loop contains another case with processing methods for accessing one of the menu items, which is enclosed in puts , each menu item of the cycle is a separate processing method. - Denis T. Nov.
  • Hmm, so if the menu not called anywhere, where does the output in the terminal come from? Write menu() where loop used to be. - Igor
