This sequence of using PowerPoint in Normal, Notes Page, and then Slide Sorter views is the norm today, and it de nes the standard for PowerPoint approaches. The secret to unlocking the power of BBP is to ip this sequence and always work in PowerPoint in Slide Sorter view rst, then in Notes Page view, and nally in Normal view. As this chapter explains, when you discover this new order for using the same features that have been around for two decades, you will teach an old PowerPoint dog new tricks. And when you apply the new sequence to your own presentations, you ll see how BBP taps into the powerful potential of PowerPoint that has been waiting for you all along.

These aren t elaborate conversations, but the first two responses are valid English and are the sort of thing your bot can use. The third response highlights that you also need to pay attention to conjugating am to are and vice versa when using I and you. You ll add the basic pronoun-switching feature as a class method on the WordPlay class. As this feature won t be chained with other methods and doesn t need to be particularly concise, you can put it into the WordPlay class rather than continue to add more methods to the String class.

def self.switch_pronouns(text) text.gsub(/\b(I am|You are|I|You|Your|My)\b/i) do |pronoun| case pronoun.downcase when "i" "you" when "you" "I" when "i am" "you are" when "you are" "i am" when "your" "my" when "my" "your" end end end

The Ribbon has been minimized throughout the gures in this book to make the graphics more visible. If you ever need to minimize your Ribbon, click the Customize Quick Access Toolbar button next to the Quick Access Toolbar on the upper left in the PowerPoint window, and then select Minimize The Ribbon.

This method accepts any text supplied as a string, and performs a substitution on each instance of I am, you are, I, you, your, or my. Next, a case construction is used to substitute each pronoun with its opposing pronoun. (You first used the case/when syntax in 3, where you can also find a deeper explanation of how it works.)

'Sir Lancelot' This means that you have to worry about the contents of globalName when you use instances (objects) of the class OpenObject. In fact, you have to make sure that nobody changes it: >>> globalName = 'Sir Gumby' >>> o.getName() 'Sir Gumby' Things get even more problematic if you try to create more than one OpenObject because they will all be messing with the same variable: >>> o1 = OpenObject() >>> o2 = OpenObject() >>> o1.setName('Robin Hood') >>> o2.getName() 'Robin Hood' As you can see, setting the name of one automatically sets the name of the other. Not exactly what you want. Basically, you want to treat objects as abstract. When you call a method you don t want to worry about anything else, such as not disturbing global variables. So how can you encapsulate the name within the object No problem. You make it an attribute. Attributes are variables that are a part of the object, just like methods; actually methods are almost like attributes bound to functions. (You ll see an important difference between methods and functions in the section Attributes, Functions, and Methods, later in this chapter.) If you rewrite the class to use an attribute instead of a global variable, and you rename it ClosedObject, it works like this: >>> c = ClosedObject() >>> c.setName('Sir Lancelot') >>> c.getName() 'Sir Lancelot' So far, so good. But for all you know, this could still be stored in a global variable. Let s make another object: >>> r = ClosedObject() >>> r.setName('Sir Robin') r.getName() 'Sir Robin' Here we can see that the new object has its name set properly. Well, we expected that. But what has happened to the first object now >>> c.getName() 'Sir Lancelot'

The reason for performing a substitution in this way is so that you only change each pronoun once. If you d used four gsubs to change all I s to you s, you s to I s, and so on, changes made by the previous gsub would be overwritten by the next. Therefore, it s important to use one gsub that scans through the input pronoun by pronoun rather than making several blanket substitutions in succession. Let s check the results:
