779:
780: This module publishes a directory of files.
781:
782: This is part of the LearningOnline Network with CAPA project
783: described at http://www.lon-capa.org.
784:
785: =head1 HANDLER SUBROUTINE
786:
787: This routine is called by Apache and mod_perl.

791: =item *
792:

797: start page output
798:
799: =item *
800:
801: run through list of files and attempt to publish unhidden files

806:
807: =over
808:
809: =item startpage($r, $uame, $udom, $thisdisfn)
810:
811: Output the header of the page. This includes:
812: - The HTML header
813: - The H1/H3 stuff which includes the directory.
814:
815: startpage($r, $uame, $udom, $thisdisfn);
816: $r - The apache request object.
817: $uname - User name.
818: $udom - Domain name the user is logged in under.
819: $thisdisfn - Displayable version of the filename.
820:
821: =item getTitleString($fullname)
822:
823: Get the title string or "[untitled]" if the file has no title metadata:
824: Without the latter substitution, it's impossible to examine metadata for
825: untitled resources. Resources may be legitimately untitled, to prevent
826: searches from locating them.
827:
828: $str = getTitleString($fullname);
829: $fullname - Fully qualified filename to check.
830:
831: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
832: $numdir)
833:
834: Put out a directory table row:
835:
836: $r - Apache request object.
837: $reqfile - File in request.
838: $here - Where we are in directory tree.
839: $dirname - Name of directory special file.
840: $modtime - Encoded modification time.
841: targetdir - Publication target directory.
842: bombs - Reference to hash of URLs with runtime error messages.
843: numdir - Reference to scalar used to track number of sub-directories
844: in directory (used in form name for each "actions" dropdown).
