def have_validator?(name)
  self.class.validators.map { |g| g.name.to_s }.include?(name)
end

#needs_help?(params) ⇒ Boolean

In the Base class, this is defined to be true if any args match “-h” or “–help”. Here we override that behavior such that if the first argument is a valid validator name, like ‘pfm validate server-build -h`, we delegate the request to the specified validator.

Returns:

  • (Boolean)
