722: =head1 INTRODUCTION
723:
724: This module publishes a directory of files.
725:
726: This is part of the LearningOnline Network with CAPA project
727: described at http://www.lon-capa.org.
728:
729: =head1 HANDLER SUBROUTINE
730:
731: This routine is called by Apache and mod_perl.
732:
733: =over 4
734:
735: =item *
736:
737: read in information
738:
739: =item *
740:
741: start page output
742:
743: =item *
744:
745: run through list of files and attempt to publish unhidden files

749: =head1 SUBROUTINES:
750:
751: =over
752:
753: =item startpage($r, $uame, $udom, $thisdisfn)
754:
755: Output the header of the page. This includes:
756: - The HTML header
757: - The H1/H3 stuff which includes the directory.
758:
759: startpage($r, $uame, $udom, $thisdisfn);
760: $r - The apache request object.
761: $uname - User name.
762: $udom - Domain name the user is logged in under.
763: $thisdisfn - Displayable version of the filename.
764:
765: =item getTitleString($fullname)
766:
767: Get the title string or "[untitled]" if the file has no title metadata:
768: Without the latter substitution, it's impossible to examine metadata for
769: untitled resources. Resources may be legitimately untitled, to prevent
770: searches from locating them.
771:
772: $str = getTitleString($fullname);
773: $fullname - Fully qualified filename to check.
774:
775: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
776: $numdir)
777:
778: Put out a directory table row:
779:
780: $r - Apache request object.
781: $reqfile - File in request.
782: $here - Where we are in directory tree.
783: $dirname - Name of directory special file.
784: $modtime - Encoded modification time.
785: targetdir - Publication target directory.
786: bombs - Reference to hash of URLs with runtime error messages.
787: numdir - Reference to scalar used to track number of sub-directories
788: in directory (used in form name for each "actions" dropdown).
