CSC151.02 2003F, Class 14: Talk Like a Pirate Day

Admin:
* I may be a few minutes late for today's class.
* New homework (extension of today's class)
* New reading: Repetition with Recursion
* Today's goal: Program that turns "landlubber english" into pirate-talk

Overview:
* Techniques for changing dialect
* Specific instances for piratization
* Some useful Scheme
* Lab

What are some general techniques that the Shizzalotor and other services use?
* Particular word changes, e.g. "for" to "fo'"
* Add some suffixes to sentences, e.g. "... 'n sh*t".
* Sometimes letter changes, e.g., "v" to "b"
* Removes certain words (e.g., "to")

How might we apply these various techniques?
* Word changes
  * "Hello" -> "Ahoy"
  * "My" -> "Me"
  * "Woman" -> "Beauty"
  * "Man" -> "bilge rat" or "scallywag" or "ugly" or ...
* Additions to the end of sentence
  * ", matey"
  * ", me 'earty"
  * ".  Saavy?"
  * ",  arrhhh."

Translator should be comparatively easy: Replace words, Replace ends of sentences

Start easy: The one-word-pirate-translator
Extend so that it still takes one word as input, but can handle different words

Hard part: Going from a long phrase to a set of words.
  (split "llasdasdfadffa aadsfd") -> list of words
  (join ("  " "asdfas" "asdfas") -> single word

We have a list of words and we know how to change individual words
Scheme includes "map" for just that purpose.

Do the lab.

/Reflection/

* Here's an interesting sample phrase (from Kennedy's innaugural address)
And so, my fellow Americans: ask not what your country can do for you--ask what you can do for your country.  My fellow citizens of the world: ask not what America will do for you, but what together we can do for the freedom of man.

* A better way to deal with lots of possibilities
	(list-ref (list "bilge-rat" "landlubber" "mate" "bastard") (random 4))

* How would you write "add the word 'slimy' before some nouns"?
