Constructor Details

#initialize(h) ⇒ TtsMessage

take an hash in parameter, with at least :tts key. the :tts key must be a string encoded in UTF-8. Optionals parameters are :speed and :pitch, they must be between MIN_SPEED and MAX_SPEED (MIN_PITCH and MAX_PITCH respectively). Default values for speed/pitch is 100.

Raises:

• (ArgumentError)

# File 'lib/violet/request.rb', line 184

def initialize h
  raise ArgumentError.new('no :tts given') unless h[:tts]
  @h = h.dup

  [:speed,:pitch].each do |k|
    min = Helpers.constantize("#{self.class}::MIN_#{k.to_s.upcase}")
    max = Helpers.constantize("#{self.class}::MAX_#{k.to_s.upcase}")

    unless @h[k].to_i.between?(min,max)
      raise ArgumentError.new("#{k} values must be between #{min} and #{max}")
    else
      @h[k] = @h[k].to_i
    end if @h[k]
  end

  # to have a well formatted url
  @h[:tts]          = URI.escape @h[:tts]
  @h[:nabcasttitle] = URI.escape @h[:nabcasttitle] if @h[:nabcasttitle]
