###################################################################### =item $xhtmlfragment = eprint_render( $eprint, $session, $preview ) This subroutine takes an eprint object and renders the XHTML view of this eprint for public viewing. Takes two arguments: the L<$eprint\|EPrints::DataObj::EPrint> to render and the current L<$session\|EPrints::Session>. Returns three XHTML DOM fragments (see L<EPrints::XML>): C<$page>, C<$title>, (and optionally) C<$links>. If $preview is true then this is only being shown as a preview. (This is used to stop the "edit eprint" link appearing when it makes no sense.) =cut ###################################################################### $c->{eprint_render} = sub { my( $eprint, $session, $preview ) = @_; my $succeeds_field = $session->get_repository->get_dataset( "eprint" )->get_field( "succeeds" ); my $commentary_field = $session->get_repository->get_dataset( "eprint" )->get_field( "commentary" ); my $has_multiple_versions = $eprint->in_thread( $succeeds_field ); my( $page, $p, $a ); $page = $session->make_doc_fragment; # Citation $p = $session->make_element( "p", class=>"ep_block", style=>"margin-bottom: 1em" ); $p->appendChild( $eprint->render_citation() ); $page->appendChild( $p ); # Put in a message describing how this document has other versions # in the repository if appropriate if( $has_multiple_versions ) { my $latest = $eprint->last_in_thread( $succeeds_field ); my $block = $session->make_element( "div", class=>"ep_block", style=>"margin-bottom: 1em" ); $page->appendChild( $block ); if( $latest->get_value( "eprintid" ) == $eprint->get_value( "eprintid" ) ) { $block->appendChild( $session->html_phrase( "page:latest_version" ) ); } else { $block->appendChild( $session->render_message( "warning", $session->html_phrase( "page:not_latest_version", link => $session->render_link( $latest->get_url() ) ) ) ); } } # Contact email address my $has_contact_email = 0; if( $session->get_repository->can_call( "email_for_doc_request" ) ) { if( defined( $session->get_repository->call( "email_for_doc_request", $session, $eprint ) ) ) { $has_contact_email = 1; } } # Available documents my @documents = $eprint->get_all_documents(); my $docs_to_show = scalar @documents; $p = $session->make_element( "p", class=>"ep_block", style=>"margin-bottom: 1em" ); $page->appendChild( $p ); if( $docs_to_show == 0 ) { $p->appendChild( $session->html_phrase( "page:nofulltext" ) ); if( $has_contact_email && $eprint->get_value( "eprint_status" ) eq "archive" ) { # "Request a copy" button my $form = $session->render_form( "get", $session->get_repository->get_conf( "perl_url" ) .

=item $xhtmlfragment = eprint_render( $eprint, $session, $preview )

This subroutine takes an eprint object and renders the XHTML view
of this eprint for public viewing.

Takes two arguments: the L<$eprint|EPrints::DataObj::EPrint> to render and the current L<$session|EPrints::Session>.

Returns three XHTML DOM fragments (see L<EPrints::XML>): C<$page>, C<$title>, (and optionally) C<$links>.

If $preview is true then this is only being shown as a preview.
(This is used to stop the "edit eprint" link appearing when it makes
no sense.)
