Rake - capture :task_name as an option?

Question

I am watching a Peepcode screencast Play by Play: Jim Weirich.

He executes a rake task that appears to pass the final task name as an option.

See how the task :demo creates a "demo" folder. How was this done?

EDIT:

Thanks, Alex.Bullard.

So with something like this:

namespace :project do
    namespace :ruby do
        rule "" do |t|
            puts t.name
        end
    end
end

Running $ rake project:ruby:demo outputs project:ruby:demo.

Do I have to t.name.split(":") or is there a way to grab just that final name?

Answer 1

If you define a task like this:

  namespace :test do
    rule "" do |t|
      # t.name is 'test::[whatever]"
    end
  end

Then the "" task will act as a catchall and you can use its name as an argument for whatever you want
