[LRUG] Rake problem with gets

[James Adam]

As I recall, Rake changes the default $stdout/$stdin arrangement. If you call

  STDIN.gets

It should work. I've just tried this

Rakefile:
task :getting do
  print 'What is your name: '
  x = STDIN.gets
  puts "You'll never be as good as Steven Seagal, #{x}"
end

$ rake getting
(in /private/tmp)
What is your name: James
You'll never be as good as Steven Seagal, James
