735: =head1 INTRODUCTION
736:
737: This module publishes a directory of files.
738:
739: This is part of the LearningOnline Network with CAPA project
740: described at http://www.lon-capa.org.
741:
742: =head1 HANDLER SUBROUTINE
743:
744: This routine is called by Apache and mod_perl.
745:
746: =over 4
747:
748: =item *
749:
750: read in information
751:
752: =item *
753:
754: start page output
755:
756: =item *
757:
758: run through list of files and attempt to publish unhidden files

762: =head1 SUBROUTINES:
763:
764: =over
765:
766: =item startpage($r, $uame, $udom, $thisdisfn)
767:
768: Output the header of the page. This includes:
769: - The HTML header
770: - The H1/H3 stuff which includes the directory.
771:
772: startpage($r, $uame, $udom, $thisdisfn);
773: $r - The apache request object.
774: $uname - User name.
775: $udom - Domain name the user is logged in under.
776: $thisdisfn - Displayable version of the filename.
777:
778: =item getTitleString($fullname)
779:
780: Get the title string or "[untitled]" if the file has no title metadata:
781: Without the latter substitution, it's impossible to examine metadata for
782: untitled resources. Resources may be legitimately untitled, to prevent
783: searches from locating them.
784:
785: $str = getTitleString($fullname);
786: $fullname - Fully qualified filename to check.
787:
788: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
789: $numdir)
790:
791: Put out a directory table row:
792:
793: $r - Apache request object.
794: $reqfile - File in request.
795: $here - Where we are in directory tree.
796: $dirname - Name of directory special file.
797: $modtime - Encoded modification time.
798: targetdir - Publication target directory.
799: bombs - Reference to hash of URLs with runtime error messages.
800: numdir - Reference to scalar used to track number of sub-directories
801: in directory (used in form name for each "actions" dropdown).
