| Description: | a utility to translate an email or any text to HTML numeric entities. I generally use this to translate email addresses on web pages into numeric entities - the thought is that it may keep spiders from grabbing email addresses. Im not exactly sure if it does or not, but ignorance is bliss ;) It doesnt tolerate undefined characters. |
#!/usr/bin/perl -w
use strict;
my $email = $ARGV[0] or die "no email address given\n";
# setup our alphabet
my @alphabet = qw(a b c d e f g
h i j k l m n
o p q r s t u
v w x y z);
# Translate non alphanumerics first
my %translate=( "." => "46",
"-" => "45",
"\@" => "64",
" " => "32",
"_" => "95");
# translate our numbers
for ( 0 .. 9 )
{
$translate{$_} = $_ + 48;
}
# translate our alphabet
for ( 0 .. 25 )
{
$translate{$alphabet[$_]} = $_ + 97;
$translate{ uc $alphabet[$_]} = $_ + 65;
}
print "&#" . sprintf("%03d", $translate{$_}) for (split //, $email);
print "\n";
