@teachpack["hangman"]{Hangman}

@defmodule[#:require-form beginner-require htdp/hangman]

The teachpack implements the callback functions for playing a
@emph{Hangman} game, based on a function designed by a student. The player
guesses a letter and the program responds with an answer that indicates
how many times, if at all, the letter occurs in the secret word.

@defproc[(hangman [make-word (-> symbol? symbol? symbol? word?)][reveal (-> word? word? word?)][draw-next-part (-> symbol? true)]) true]{
Chooses a ``secret'' three-letter word and uses the given functions to
manage the @emph{Hangman} game.}

@defproc[(hangman-list
	   [reveal-for-list (-> symbol? (list-of symbol?) (list-of symbol?)
			        (list-of symbol?))]
	   [draw-next-part (-> symbol? true)]) true]{
Chooses a ``secret'' word---a list of symbolic letters---and uses the given
functions to manage the @emph{Hangman} game: 
@racket[reveal-for-list] determines how many times the chosen letter occurs
in the secret word; 
@racket[draw-next-part] is given the symbolic name of a body part and draws
it on a separately managed canvas.
}

In addition, the teachpack re-exports the entire functionality of the
drawing library; see @secref{draw} for documentation.
