This week, we will make some ascii-art for fun.

Produce a script that generates funny talking animals. The executable
consists of three parts.

Part One : The balloon
=====================

The balloon is the surrounding part, in which the text will be shown. You can
make it like you want.

Examples :

One-liner
_______________
< I love ruby ! >
---------------

Multiple lines with text wrapping and carriage return
__________________________________________
/ Q:How do you stop an elephant from \
| charging? |
\ A:Take away his credit cards. /
------------------------------------------

Part Two : The template
=======================

To make it flexible, we'll need a template language that can combine the animal
and the text. You'll have to think about how you want to make it flexible
enough.

Example :

# thoughts is the balloon's tail
def animal(thoughts = '\', eyes = 'oo', tongue=' ')
%[#{baloon}
#{thoughts} ^__^
#{thoughts} (#{eyes})\\_______
(__)\\ )\\/\\
#{tongue} ||----w |
|| ||
]
end

Part Three : The command-line arguments
=======================================

There are no special arguments. I would suggest asking for a text input, but you
can also get the text from `fortune` or make it editable in place. Optional
arguments can be given to change the selected template and some of its
variables like the eyes, the tongue, and the balloon's tail.

Use your imagination !

So that's it for the quiz. Extra points are given to the person who
provides a duck template.

I thought so too. Submitters always make better quizzes than me,
which is why I encourage them so much. ;)

This is a terrific problem for beginners, so hopefully we'll see some
new names in the solutions!

Well, I'm new on this quiz thingy... And I've already have some results to
show off (which I hope isn't a spoiler):

/The quick brown fox jumps\
\ over the lazy dog. /
-------------------------
\
` >(o)____,
(` =~~/
^~^~^~^~^~`---'^~^~^~^~^~^~^~^~^~^~
I've sacrificed a couple of characters to get flexibility on the template,
however. and no tongue. I also have the commandline arguments to take care
of as well.

Looking great! Can't wait to see it.

my solution. not very OO at all, however. I just hope the formatting doesn't
screw up on the animal template files...

This was quite fun. I decided not to go into ASCII art creation and
"cheated" by getting some wacky animals from http://www.ascii-art.de,
including several ducks. As noted in the source I developed this on a
Windows machine which does not have fortune (at least without getting
Cygwin, etc.), so I found a CGI script online which has fortune, and I
use open-uri to access it.

I'm sure my "bubble maker" could be golfed down a bit, but I preferred
clarity over terseness.

All the animals in the "zoo" are embedded in the DATA section of the
script, with a special format to delimit them. It is fairly easy to
add new animals should one want to.

I also used a different style of command-line options, since it fit
this problem. Here is an example run:

C:\_Ryan\ruby\quiz\52_ducksay>ruby ducksay.rb gecko.say "Ruby Rocks!"

It's my favourite line in the program, too. I was going to point it out in
my post, but I decided to paste instead of link.

Historical note: I originally wrote it the other way around, basing
everything on the Cow, but that's clearly not how it's meant to be.

BTW, another Cowsay reference:
http://www.nog.net/~tony/warez/cowsay.shtml

The above lists the cowsay perl software in its various forms, including the
CPAN module Acme::Cow.

Cheers,
