Is there a way to programmatically answer prompts?

[cswilliams]

I'd like to add a --yes option to my program where it will automatically answer "yes" to any yes/no prompts.

Is there any supported way in the library to do this? I realize I can just skip over the prompt entirely, but it still would be nice if the output on the screen looked the same as if the user answered "yes". I came up with something like this, but was wondering if there was a better way? Thanks!!

require 'tty-prompt'
prompt = TTY::Prompt.new(interrupt: :exit)
question = "Do you like Ruby?"
yes = true if ARGV[0] == "--yes"
color = Pastel.new

if yes
  puts "#{question} #{color.green("Yes")}"
else
  prompt.yes?(question)
end

Hi Chris,

I like your solution, it's neat. Another approach could be to provide a 'scripted' input to the prompt like so:

if yes
  input = StringIO.new
  input << "y\n"
  input.rewind
  prompt = TTY::Prompt.new(input: input)
end

prompt.yes?("Do you like Ruby?")

I used this approach to test the service_actor-promptable gem. It works well!
