Parameter indentation

Whenever a number of values are being passed as parameter, make the first parameter in-line. What that means is that the first parameter should be in the same line as the method that is being invoked. Now the second parameter can come below the first parameter.

This is an example of code which we would not recommend:

Analytics.identify(
  user_id: user.id,
  traits: { email: user.email,
            name: user.name,
            first_name: user.first_name,
            last_name: user.last_name,
            phone: user.phone } )

And this is an example of a code style that we would recommend:

Analytics.identify( user_id: user.id,
                    traits: { email: user.email,
                              name: user.name,
                              first_name: user.first_name,
                              last_name: user.last_name,
                              phone: user.phone } )
