Is it possible to make an interactive Rake task?

I want to run a Rake task that asks the user for input.

I know that I can supply input on the command line, but I want to ask the user if they are sure they want to proceed with a particular action in case they mistyped one of the values supplied to the Rake task.

Solution

  • Something like this might work

    task :action do
  STDOUT.puts "I'm acting!"
end

task :check do
  STDOUT.puts "Are you sure? (y/n)"
  input = STDIN.gets.strip
  if input == 'y'
    Rake::Task["action"].reenable
    Rake::Task["action"].invoke
  else
    STDOUT.puts "So sorry for the confusion"
  end
end
