826:
827: This module publishes a directory of files.
828:
829: This is part of the LearningOnline Network with CAPA project
830: described at http://www.lon-capa.org.

838: =item *
839:

843:
844: start page output
845:
846: =item *
847:
848: run through list of files and attempt to publish unhidden files

852: =head1 SUBROUTINES:
853:
854: =over
855:
856: =item startpage($r, $uame, $udom, $thisdisfn)
857:
858: Output the header of the page. This includes:
859: - The HTML header
860: - The H1/H3 stuff which includes the directory.
861:
862: startpage($r, $uame, $udom, $thisdisfn);
863: $r - The apache request object.
864: $uname - User name.
865: $udom - Domain name the user is logged in under.
866: $thisdisfn - Displayable version of the filename.
867:
868: =item getTitleString($fullname)
869:
870: Get the title string or "[untitled]" if the file has no title metadata:
871: Without the latter substitution, it's impossible to examine metadata for
872: untitled resources. Resources may be legitimately untitled, to prevent
873: searches from locating them.

876: $fullname - Fully qualified filename to check.
877:
878: =item putdirectory(r, base, here, dirname, modtime)
879:
880: Put out a directory table row:
881:
882: putdirectory($r, $base, $here, $dirname, $modtime)
883: $r - Apache request object.
884: $reqfile - File in request.
885: $here - Where we are in directory tree.
886: $dirname - Name of directory special file.
887: $modtime - Encoded modification time.
888:
889: =item CategorizeFiles($location, $files)
890:
891: Categorize files in the directory.
892: For each file in a list of files in a file directory,
893: the file categorized as one of:
894: - directory
895: - sequence
896: - problem
897: - Other resource.
898:
899: For each file the modification date is determined as well.
900: Returned is a list of sublists:
901: (directories, sequences, problems, other)
902: each of the sublists contains entries of the following form (sorted by filename):
903: (filename, typecode, lastmodtime)
904:
905: $list = CategorizeFiles($location, $files)
906: $location - Directory in which the files live (relative to our execution)
907: $files - list of files.
