987:
988: This module publishes a directory of files.
989:
990: This is part of the LearningOnline Network with CAPA project
991: described at http://www.lon-capa.org.
992:
993: =head1 HANDLER SUBROUTINE
994:
995: This routine is called by Apache and mod_perl.

1005: start page output
1006:
1007: =item *
1008:
1009: run through list of files and attempt to publish unhidden files

1015: =over
1016:
1017: =item startpage($r, $uame, $udom, $thisdisfn)
1018:
1019: Output the header of the page. This includes:
1020: - The HTML header
1021: - The H1/H3 stuff which includes the directory.
1022:
1023: startpage($r, $uame, $udom, $thisdisfn);
1024: $r - The apache request object.
1025: $uname - User name.
1026: $udom - Domain name the user is logged in under.
1027: $thisdisfn - Displayable version of the filename.
1028:
1029: =item getTitleString($fullname)
1030:
1031: Get the title string or "[untitled]" if the file has no title metadata:
1032: Without the latter substitution, it's impossible to examine metadata for
1033: untitled resources. Resources may be legitimately untitled, to prevent
1034: searches from locating them.
1035:
1036: $str = getTitleString($fullname);
1037: $fullname - Fully qualified filename to check.

1045: $reqfile - File in request.
1046: $here - Where we are in directory tree.
1047: $dirname - Name of directory special file.
1048: $modtime - Encoded modification time.
1049: targetdir - Publication target directory.
1050: bombs - Reference to hash of URLs with runtime error messages.
1051: numdir - Reference to scalar used to track number of sub-directories
1052: in directory (used in form name for each "actions" dropdown).
