Since eyepopslikeamosquito laid out a breif history of the JAPH, I figured I might as well add one of the few that I ever wrote. I'm not much into obfus or code in sigs or what not, but I did have an idea for a JAPH after watching The Matrix a couple times, and up until then I hadn't seen anyone use the entire screen and rand() to make the right string pop up.

I did have a obfuscated version of this somewhere, but I can't find it. Just remove most of the whitespace and shorten all the variable names.

Update: fixed eyepopslikeamosquito (twice) :(

#!/usr/bin/perl -w use strict; use Curses; my @LETTERS = ( 'A' .. 'Z', 'a' .. 'z', ',', ' ' ); $SIG{TERM} = sub { exit }; my $STRING = 'Just Another Perl Hacker,'; my $LENGTH = length $STRING; initscr; my $ROW = ( LINES() % 2 ? LINES() - 1 : LINES() ) / 2; my $COLUMN = ( COLS() % 2 ? COLS() - 1 : COLS() ) / 2 - ( $LENGTH % 2 ? $LENGTH - 1 : $LENGTH ) / 2; my $END_COL = $COLUMN + $LENGTH - 1; my @array; my $count = 0; my $x = random( LINES ); my $y = random( COLS ); my $letter = sub { $LETTERS[ int( rand( @LETTERS ) ) ] }; while( 1 ) { my $x = &$x; my $y = &$y; my $letter = &$letter; next if( $x == $ROW and $array[$y] ); if( $x == $ROW and $y >= $COLUMN and $y <= $END_COL and substr( $STRING, $y - $COLUMN, 1 ) eq $letter ) { $array[$y]++; $count++; } put_letter( $letter, $x, $y ); if( $count == $LENGTH ) { @LETTERS = ' '; } } sub random { my $range = shift; sub { int ( rand ( $range ) ) } } sub put_letter { my ($letter, $x, $y) = @_; addch( $x, $y, $letter ); refresh; }
