Web::MREST::Util - Miscellaneous utilities
=head1 SYNOPSIS
Miscellaneous utilities
=head1 EXPORTS
This module provides the following exports:
=over
=item C<$JSON> (singleton)
=item C<pod_to_html> (function)
=item C<pod_to_text> (function)
=back
=cut
use Exporter qw( import );
our @EXPORT_OK = qw(
$JSON
pod_to_html
pod_to_text
);
=head1 FUNCTIONS
=head2 pod_to_html
Every L<Web::MREST> resource definition includes a 'documentation'
property containing a POD string. Our 'docu/html' resource converts this
POD string into HTML with a little help from this routine.
=cut
sub pod_to_html {
my ( $pod_str ) = @_;
$log->debug( "Entering " . __PACKAGE__ . "::pod_to_html" );
#$log->debug( "pod_to_html before: $pod_str" );
my $p = Pod::Simple::HTML->new;
$p->output_string(\my $html_str);
$p->parse_string_document($pod_str);
# now $html_str contains a full-blown HTML file, of which only one part is
# of interest to us. That part starts with the line <!-- start doc --> and
# ends with <!-- end doc -->
$html_str =~ s/.*<!-- start doc -->//s;
$html_str =~ s/<!-- end doc -->.*//s;
$log->debug( "pod_to_html after: $html_str" );
return $html_str;
}
=head2 pod_to_text
Convert POD string into text
=cut

$log->debug( "Entering " . __PACKAGE__ . "::pod_to_text" );
