=head1 NAME
Acme::EyeDrops - Visual Programming in Perl
=head1 SYNOPSIS
use Acme::EyeDrops qw(sightly);
print sightly( { Shape => 'camel',
SourceFile => 'eyesore.pl' } );
=head1 DESCRIPTION
C<Acme::EyeDrops> converts a Perl program into an equivalent one,
but without all those unsightly letters and numbers.
In a Visual Programming breakthrough, EyeDrops allows you to pour
the generated program into various shapes, such as UML diagrams,
enabling you to instantly understand how the program works just
by glancing at its new and improved visual representation.
Unlike C<Acme::Bleach> and C<Acme::Buffy>, the generated program runs
without requiring that C<Acme::EyeDrops> be installed on the target
system.
=head1 EXAMPLES
=head2 Getting Started
Suppose you have a program, F<helloworld.pl>, consisting of:
print "hello world\n";
To convert this little program into an equivalent camel-shaped one,
create F<cvt.pl> as follows:
# cvt.pl. Convert helloworld.pl into a camel shape.
use Acme::EyeDrops qw(sightly);
print sightly( { Shape => 'camel',
SourceFile => 'helloworld.pl',
Regex => 1 } );
Then run it like this:
perl cvt.pl >new.pl
After inspecting the newly created program, F<new.pl>, to verify that
it does indeed resemble a camel, run it:
perl new.pl
to confirm it behaves identically to the original F<helloworld.pl>.
Instead of using the API, as shown above, you may find it more
convenient to use the F<sightly.pl> command in the F<demo> directory:
sightly.pl -h (for help)
sightly.pl -s camel -f helloworld.pl -r 1 >new.pl
cat new.pl (should look like a camel)
perl new.pl (should print "hello world" as before)
Notice that the shape C<'camel'> is just the file F<camel.eye> in
the F<EyeDrops> sub-directory underneath where F<EyeDrops.pm> is located,
so you are free to add your own new shapes as required.
For the meaning of Regex => 1 above, see the I<Just another Perl hacker>
section below.
=head2 Making Your Programs Easier to Understand
If your boss demands a UML diagram describing your program, you
can give him this:
print sightly( { Shape => 'uml',
SourceFile => 'helloworld.pl',
Regex => 1 } );
If it is a Windows program, you can indicate that too, by
combining shapes:
print sightly( { Shape => 'uml,window',
Gap => 1,
SourceFile => 'helloworld.pl',
Regex => 1 } );
producing this improved visual representation:

This is perhaps a cleaner solution, though some people
find the plain sightly encoding more pleasing to the eye.
Showing the face upside down, rather than reflected, is more
easily solved with:
open$%;print+reverse<0>
and easier still for a self-printing shape:
open$%;print<0> # self printing
open$%;print+map{y;!-~;#;;$_}<0> # replace sightly with '#'
=head2 A Somersaulting Camel
Let's extend the Buffy example of the previous section to produce
a camel-shaped program capable of somersaulting across the screen
when run.
We start with a generator program, F<gencamel.pl>:
print sightly( { Regex => 1,
Compact => 1,
RemoveNewlines => 1,
Indent => 1,
BorderGapRight => 1,
Shape => 'camel',
SourceString => <<'END_SRC_STR' } );
$~=pop||'';open$%;
y,!-~,#,,s,(.).,$+,gs,$~&&($_=reverse)for@~=grep$|--,('')x18,<0>;
@;=map~~reverse,reverse@~;
map{system$^O=~Win?CLS:'clear';
($-=$_%3)||(--$|,map$_=reverse,@~,@;);
print$"x($=/3*abs$|*2-$-),$_,$/for$-&1?@;:@~;
sleep!$%}$%..11
END_SRC_STR
Note the use of the Compact and RemoveNewlines attributes,
necessary here to squeeze the above program into a single
camel shape.
Running this program:
perl gencamel.pl >camel.pl
produces F<camel.pl>:
''=~('(?{'.(
('`')| '%').('['^'-').
('`'|'!'). ('`'|',').'"\\$~='

You can run F<camel.pl> like this:
perl camel.pl normal forward somersaulting camel
perl camel.pl b camel somersaults backwards
perl camel.pl please do a backward somersault
same thing
You are free to add a leading C<#!/usr/bin/perl -w> line to
F<camel.pl>, so long as you also add a blank line after
this header line.
=head2 Twelve Thousand and Thirty Two Camels
In a similar way to the somersaulting camel described above,
we create a camel-shaped program capable of emitting
twelve thousand and thirty two different camels when run.
As usual, we start with a generator program, F<gencamel.pl>:
print sightly( { Regex => 1,
Compact => 1,
RemoveNewlines => 1,
BorderGap => 1,
Shape => 'camel',
SourceString => <<'END_SRC_STR' } );
$~=uc shift;$:=pop||'#';open$%;chop(@~=<0>);$~=~R&&
(@~=map{$-=$_+$_;join'',map/.{$-}(.)/,@~}$%..33);
$|--&$~=~H&&next,$~!~Q&&eval"y, ,\Q$:\E,c",$~=~I&&
eval"y, \Q$:\E,\Q$:\E ,",$~=~M&&($_=reverse),
print$~=~V?/(.).?/g:$_,$/for$~=~U?reverse@~:@~
END_SRC_STR
Running this program:
perl gencamel.pl >camel.pl
produces F<camel.pl>, which you can run like this:
perl camel.pl normal camel
perl camel.pl q quine (program prints itself)
perl camel.pl m mirror (camel looking in the mirror)
perl camel.pl i inverted camel
perl camel.pl u upside-down camel
perl camel.pl r rotated camel
perl camel.pl h horizontally-squashed camel
perl camel.pl v vertically-squashed camel
And can further combine the above options, each combination
producing a different camel, for example:
perl camel.pl uri
produces a large, bearded camel with a pony-tail, glasses,
and a tie-dyed T-shirt. :)
F<camel.pl> also accepts an optional second argument, specifying
the character to fill the camel with (default C<#>).
For example:
perl camel.pl hv small camel filled with #
perl camel.pl hv "$" small camel filled with $
Why 12,032 camels? Combining the main options q, m, i, u, r, h, v
can produce 128 different camels. And there are 94 printable
characters available for the second argument, making a total
of 128 * 94 = 12,032 camels.
=head2 Naked Arm Wrestling
The final auction at Y::E 2002 in Munich featured an epic athletic
contest which you can remember with:
use Acme::EyeDrops qw(sightly);
my $s = sightly( { Regex => 1,
Shape => 'naw',
Indent => 1,
SourceString => <<'NAKED_ARM_WRESTLING' } );
$/='';open$%;$x=<0>;$y=<0>;
substr($y,428,$%)=' AAAAARRRGGGHHH!!!';
map{system$^O=~Win?CLS:'clear';
print$_&1?$y:$x;sleep!$%+($_&1)}$%..9
NAKED_ARM_WRESTLING
$s =~ s/ +$//m;
print $s;
=head2 Baghdad Bob
Running this program:
print sightly( { Shape => 'baghdad',
Regex => 1,
Compact => 1,
RemoveNewlines => 1,
BorderGap => 1,
BorderWidthLeft => 3,
BorderWidthRight => 3,
BorderWidthTop => 2,
BorderWidthBottom => 8,
SourceString => <<'FAMOUS_COMICAL_ALI_QUOTES' } );
warn+(
"Britain is not worth an old shoe!",
"There are no American infidels in Baghdad!",
"We have them surrounded in their tanks!",
"I speak better English than this villain Bush!")[rand(4)],$/
FAMOUS_COMICAL_ALI_QUOTES
produces:

On 15 August 2003, Perl/Parrot Euro-hacker and modern artist
Leon Brocard (pictured above) marched into a secluded

a black Victoria's Secret bra (pictured below) into
the air, thereby creating a brilliant contemporary
site-specific art exhibit.

The bra, donated by Elaine -HFB- Ashton, was bought by the artist
expressly for this artwork at the YAPC::Europe 2003 auction.
An interpretation of Brocard's modern masterpiece is given below:
Victoria Bra, Secret Tango (2003)
L. Brocard 1976-
This, the third work in Brocard's acclaimed "Naranja" sequence,
explodes the theme of semantic [a]chromatic aspects of aranciata
visual perception, first explored in his celebrated "Buffy" series,
and fully explores the concept of supporting relationships, which
were touched on in his earlier works. The site's central artifact
is a stark reminder of the lack of support in contemporary
relationships, with the jumbled juxtaposition of its two cups,
indicative of being discarded in a hurry, symbolizing the excessive
rapidity and tautness of modern life. As always with Brocard, it is
vital to consider the intertextuality of the title of the work, in
order to deconstruct the surface meaning of the work itself and

It is easy to create your own shapes. For some ideas on shapes,
point your search engine at I<Ascii Art> or I<Clip Art>.
If you generate some nice shapes, please send them in so they
can be included in future versions of EyeDrops.
=head2 Shape Properties
All the F<.eye> shape files have a corresponding F<.eyp>
shape property file, specifying the shape's properties.
Currently, the allowed shape properties are:
name
nick
description
cpanid
author
authorcpanid
source
lib/Acme/EyeDrops.pm view on Meta::CPAN
If using Perl 5.18+, the generated file needs a leading
"use re 'eval'" when a postive value for Regex is used.
The converted program runs inside an C<eval> which may cause
problems for non-trivial programs. A C<die> statement or
an C<INIT> block, for instance, may cause trouble.
If desperate, give the C<TrapEvalDie> and C<TrapWarn>
attributes a go, and see if they fix the problem.
If the program to be converted uses the Perl format variables
C<$:>, C<$~> or C<$^> you may need to explicitly set the
C<FillerVar> attribute to a Perl variable/s not used by the program.
Linux F</usr/games/banner> does not support the following characters:
\ [ ] { } < > ^ _ | ~
When the CPAN Text::Banner module is enhanced, it will be used
in place of the Linux banner command.

I blame Japhy and Ronald J Kimball and others on the fwp
mailing list for exposing the ''=~ trick, Jas Nagra for
explaining his C<Acme::Smirch> module, and Rajah Ankur
and Supremely Unorthodox Eric for provoking me.
I would also like to thank Ian Phillipps, Philip Newton,
Ryan King, Michael G Schwern, Robert G Werner, Simon Cozens,
and others on the fwp mailing list for their advice on
ASCII Art, imaging programs, and on which picture of
Larry to use.
Thanks also to Mtv Europe, Ronald J Kimball and Eugene
van der Pijll for their help in golfing the program in
the I<Twelve Thousand and Thirty Two Camels> section.
Keith Calvert Ivey also contributed some levity to this section.
The "Love Birds" section was provoked by Muss, Jiun and Taffy.
The thumbsup shape was derived from one originally designed by Jiun.
Ideas from Adam Antonik, Mtv Europe, Eugene van der Pijll, Ton Hospel
and Keith Calvert Ivey were used in the I<Sierpinski Triangles> section.
Thanks cog for the prod to add new Shape Properties feature.
The jon shape was derived from
F<http://www.spidereyeballs.com/os5/set1/small_os5_r06_9705.html>.
Kudos to Elaine -HFB- Ashton for showing me this.
The merlyn shape was derived from this photo
F<http://www.stonehenge.com/merlyn/my_real_proof.jpg>
of Randal singing a duet with Samantha Fox.
The simon shape was derived from a pencil sketch by the Japanese
artist Eiko Yamashita.
The candle, china1, panda and santa2 shapes were derived from similar
ones at Yanni Ellen Liu's Ascii Art collection.
