=head1 NAME
MojoMojo::Formatter::Gist - Embed Gist script
=head1 DESCRIPTION
Embed Gist script by writing {{gist <id>}}.
if you write:
{{gist 618402}}
it will be formatted, like this
<script src="https://gist.github.com/618402.js"></script>
then you can see the syntax highlighted source code.
=head1 METHODS
=head2 format_content_order
The Gist formatter has no special requirements
in terms of the order it gets run in, so it has a priority of 17.
=cut
sub format_content_order { 17 }
=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 $$content;
my @lines = split /\n/, $$content;
$$content = '';
my $re = $class->gen_re( qr/gist\s+(\d+)/ );
for my $line (@lines) {
if ( $line =~ m/$re/ ) {
$line = $class->process($c, $line, $re, $1);
}
$$content .= $line . "\n";
}
}
=head2 process
Here the actual formatting is done.
=cut
sub process {
my ( $class, $c, $line, $re, $id) = @_;
my $gist = $c->loc('Gist Script');
if (!$id || $id !~ /^\d+$/){
$line =~ s/$re/"$gist: $id ". $c->loc('is not a valid id')/e;
return $line;
}
my $url = "https://gist.github.com/$id";
my $ar = $c->action->reverse;
if ( $ar && ($ar eq 'pageadmin/edit' || $ar eq 'jsrpc/render') ){
$line =~ s!$re!<div style='width: 95%;height: 90px; border: 1px black dotted;'>$gist - <a href="$url">gist:$id</a></div>!;
$c->stash->{precompile_off} = 1;
} else {
$line =~ s!$re!<script src="$url.js"></script>!;
}
return $line;
