GMail usage example

example.rb

   callback = lambda do |result, err|
      if err
        # handle error
      else
        require_relative './mail'
        mail = ::CheckEmail::Mail.new(result)
      end
    end

mail.rb

require_relative './check_email'

class Mail < CheckEmail

  attr_accessor :result

  def message_id
    result.id
  end

  def from
    parse_header 'From'
  end

  def date
    parse_header 'Date'
  end

  def subject
    parse_header 'Subject'
  end

  def body
    text || html || payload.body.data || ''
  end

  def text
    parse_payload CheckEmail::MIME_TYPES[:text]
  end

  def html
    parsed = parse_payload(CheckEmail::MIME_TYPES[:html])
    return parsed if parsed
    text
  end

  private

  def initialize(result)
    @result = result
  end

  def payload
    result.payload
  end

  def headers
    payload.headers
  end

  def parse_payload(mime_type)
    item = (payload.parts || []).find do |part|
      part.mime_type == mime_type
    end
    return nil if item.nil? || item.body.nil?
    item.body.data
  end

  def parse_header(key)
    headers.any? { |h| h.name == key } ? headers.find { |h| h.name == key }.value : ''
  end

end

For some reason when I try to edit this Gist, the content is blank.

CheckEmail::MIME_TYPES[:html] should really be 'text/html'

CheckEmail::MIME_TYPES[:text] should really be 'text/plain'
