},
image => {

=head1 DESCRIPTION
Normally, to hyperlink to a Search Engine, you'd write:
[google SearchWord](http://www.google.com/search?q=SearchWord)
This plugin lets you write just
{{google SearchWord}}
not just Search Web, you can search images and movies
{{google:image SearchWord}}
{{google:movie SearchWord}}
=head1 METHODS
=head2 format_content_order
The SearchEngine formatter has no special requirements
in terms of the order it gets run in, so it has a priority of 16.
=cut
sub format_content_order { 16 }
=head2 format_content
Calls the formatter. Takes a ref to the content as well as the context object.
=cut
sub format_content {
my ( $class, $content, $c ) = @_;
return unless $class->module_loaded;
my @lines = split /\n/, $$content;
$$content = '';
my $re = $class->gen_re( qr/google:?([^\s]+)?\s+(.+)/ );
my $lang = $c->sessionid
? $c->session->{lang} : $c->pref('default_lang') || 'en';
for my $line (@lines) {
if ( $line =~ m/$re/ ) {
$line = $class->process($c, $line, $re, $lang);
}
$$content .= $line . "\n";
}
}
=head2 process
Here the actual formatting is done.
=cut
sub process {
my $class = shift;
my ($c, $line, $re, $lang) = @_;
my $google_search = $c->loc('Google Search Link');
$line =~ m/$re/;
my $kind = $1 || 'web';
