"Cowsay" in short [closed]

Question

Simulate cowsay in the default mode.

$ cowsay <<< Hello
 _______
< Hello >
 -------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\
                ||----w |
                ||     ||

$ perl -e 'print "Long text "x20' | cowsay
 __________________________________________
/ Long text Long text Long text Long text  \

| Long text Long text Long text Long text  |
| Long text Long text Long text Long text  |
\ Long text Long text Long text Long text  /
 ------------------------------------------
        \   ^__^
         \  (oo)\_______
            (__)\       )\/\

How short can be the code? The cow and the balloon can be slightly different, but all elements should be present. Dynamic/multiline balloon is a plus.

Explicit list of the required elements:

• Text;
• Balloon;
• Line from the cow to the balloon;
• The cow (eye[s], month, ears, body, legs (minimum two), udder, tail).

/usr/share/cowsay/cows/ may be accessed, but obviously not /usr/games/cowsay itself.

Note: here is the /usr/share/cowsay/cows/default.cow file:

$the_cow = <<"EOC";
        $thoughts   ^__^
         $thoughts  ($eyes)\\_______
            (__)\\       )\\/\\
             $tongue ||----w |
                ||     ||
EOC

Usage of the file is optional. When used, it must be accessed by full path. (Windows users may copy it to something like C:\usr\share\cowsay\co\default.cow, for fairness).

Answer 1

Mathematica: Work in progress

I'll pin down the balloon once I can get the cow to settle:

ExampleData[{"Geometry3D", "Cow"}]

Answer 2

Perl, 84 characters

print$a='-'x52,<>=~s/.{1,50}\b/sprintf"
|%-50s|",$&/rge,"$a
\\   
]:p
| )=
| P= 
 ¬"

Output:

----------------------------------------------------
|Long text Long text Long text Long text Long text |
|Long text Long text Long text Long text Long text |
|Long text Long text Long text Long text Long text |
|Long text Long text Long text Long text Long text |
----------------------------------------------------
\   
]:p
| )=
| P= 
 ¬

Admittedly, I golfed the cow as much as I golfed the code. But the Mathematica cow is going to win anyway :)

Note: Requires Perl 5.16 for the /r non-destructive substitution flag.

Answer 3

Ruby: 152 150 149 146 143 characters

load'/usr/share/cowsay/cows/default.cow'
p=%w{U~ o* o o}
puts l=?-*44,gets.gsub(/(.{1,40})\b\s*/){"( %-41s)\n"%$1}+l,$the_cow.gsub(/\$\w+/){p.pop}

The cow art is read from the default.cow file and decorated in after-12-rounds-vs-Mike-Tyson manner, similar with a cowthink -e 'o*' -T 'U~' invocation.

The text is read from standard input and wrapped at most 40 characters. Line breaks in the input text are not supported.

Sample run:

bash-4.2$ perl -e 'print "Long text "x15' | ruby cow.rb 
--------------------------------------------
( Long text Long text Long text Long text  )
( Long text Long text Long text Long text  )
( Long text Long text Long text Long text  )
( Long text Long text Long text            )
--------------------------------------------
        o   ^__^
         o  (o*)\_______
            (__)\       )\/\
             U~ ||----w |
                ||     ||

With art bending: 138 135 136 characters

load'/usr/share/cowsay/cows/default.cow'
puts l=?-*44,gets.gsub(/(.{1,40})\b\s*/){"( %-41s)\n"%$1}+l,$the_cow.gsub(/\$.+?([use]+)\b/,'\1')

As the elements have to be just present, we can use what we have in place instead of defining realistic ones.

Sample run:

bash-4.2$ ruby cow.rb <<< 'Hello poor little cow'
--------------------------------------------
( Hello poor little cow                    )
--------------------------------------------
        s   ^__^
         s  (es)\_______

APL 133 140 138 122

This one liner takes screen input in the form of a character vector or array enclosed in quotes via: ←⍎⍞ The appearance of the output is improved by including leading and following spaces in the input.

('∘'⍪'∘',((¯2↑1,⍴t)⍴t←⍎⍞),'∘')⍪'∘'⋄5 19⍴(,⍉(19⍴2)⊤323584 196592 63503 4072 3096)\'∘^__^∘(oo)\_______(__)\)\/\||----w|||||'

The cow character locations on each row of the array are specified as 19 bit boolean vectors.

To use input the one liner followed by the bubble text in quotes:

' Hello '

°°°°°°°°°
° Hello °
°°°°°°°°°
°  ^__^
 ° (oo)\_______
   (__)\       )\/\
       ||----w |
       ||     ||

Multi-line text is input as an array.

3 36⍴' Multi-line text input as an array. '
