Hi,

When I code this question,

prompt.ask('Folder name?') do |q| q.required true q.validate ->(v) { return !Dir.exist?(v) } q.messages[:valid?] = 'Folder already exists!' end

If I press directly [return], the required validation is not used ... and the validate lamba is directly processing.

To correct it , I have to write
prompt.ask('Folder name?') do |q| # q.required true q.validate ->(v) { return !v.nil? && !Dir.exist?(v) } q.messages[:valid?] = 'Folder already exists!' end

It would be great if the required method was taking account.

Hey, thanks for using the library. Good catch. Do you fancy submitting PR?

This has been added, you can now do

prompt.ask('Folder name?') do |q|
  q.required true
  q.validate ->(v) { !Dir.exist?(v) }
  q.messages[:required?] = 'Folder name cannot be empty!'
  q.messages[:valid?] = 'Folder already exists!'
end

I will release patch shortly.
