745:
746: This module publishes a directory of files.
747:
748: This is part of the LearningOnline Network with CAPA project
749: described at http://www.lon-capa.org.
750:
751: =head1 HANDLER SUBROUTINE
752:
753: This routine is called by Apache and mod_perl.
754:
755: =over 4
756:
757: =item *
758:
759: read in information
760:
761: =item *
762:
763: start page output
764:
765: =item *
766:
767: run through list of files and attempt to publish unhidden files

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