I have a rake task that is called from another rake task.
In this rake task I need to ask the user for some text input, and then, depending on the answer either continue, or stop everything from continuing (including the calling rake task).
How can I do this?

Whenever you are testing Rake tasks, you need to load the tasks from the Rails application itself. Note that in your tests you should change MyApplication to the name of your application. This line locates the task by it's name and returns a Rake::Task object. Then, we call invoke on it, which executes the task.
You can use abort("message") to gracefully fail rake task. It will print message to stdout and exit with code 1.
Rake is a popular task runner for Ruby and Rails applications. For example, Rails provides the predefined Rake tasks for creating databases, running migrations, and performing tests. You can also create custom tasks to automate specific actions - run code analysis tools, backup databases, and so on.
Go to Websites & Domains and click Ruby. After gems installation you can try to run a Rake task by clicking Run rake task. In the opened dialog, you can provide some parameters and click OK - this will be equivalent to running the rake utility with the specified parameters in the command line.
task :input_test do input = '' STDOUT.puts "What is the airspeed velocity of a swallow?" input = STDIN.gets.chomp raise "bah, humbug!" unless input == "an african or european swallow?" end task :blah_blah => :input_test do end i think that should work
