To have less env variables can pass it in URL format:

if ENV["SMTP_URL"]
  smtp_url = URI.parse(ENV["SMTP_URL"])
  self.smtp_settings = {
    address:   smtp_url.host,
    port:      smtp_url.port,
    user_name: smtp_url.user ? URI.decode_www_form_component(smtp_url.user) : nil,
    password:  smtp_url.password,
    enable_starttls_auto: Rack::Utils.parse_nested_query(smtp_url.query)['tls'].in?(['true', '1', 1, true, 'True', 'TRUE'])
  }
end

I find this useful for me:

ObjectKit.forEach = function Object_forEach (object, callback) {
  for (var key in object) {
    if (object.hasOwnProperty(key)) callback(key, object[key]);
  }
};

Here is example for travis-ci https://github.com/yamadapc/pyjamas/blob/master/.travis.yml

Thank you for link. It's almost same with manual I mentioned, paste image in "get info" window. For me it worked only if I open icon in preview.app and copy image (not a file)
