983:
984: This module publishes a directory of files.
985:
986: This is part of the LearningOnline Network with CAPA project
987: described at http://www.lon-capa.org.

989: =head1 HANDLER SUBROUTINE
990:
991: This routine is called by Apache and mod_perl.

1001: start page output
1002:
1003: =item *
1004:
1005: run through list of files and attempt to publish unhidden files

1011: =over
1012:
1013: =item startpage($r, $uame, $udom, $thisdisfn)
1014:
1015: Output the header of the page. This includes:
1016: - The HTML header
1017: - The H1/H3 stuff which includes the directory.
1018:
1019: startpage($r, $uame, $udom, $thisdisfn);
1020: $r - The apache request object.
1021: $uname - User name.
1022: $udom - Domain name the user is logged in under.
1023: $thisdisfn - Displayable version of the filename.
1024:
1025: =item getTitleString($fullname)
1026:
1027: Get the title string or "[untitled]" if the file has no title metadata:
1028: Without the latter substitution, it's impossible to examine metadata for
1029: untitled resources. Resources may be legitimately untitled, to prevent
1030: searches from locating them.
1031:
1032: $str = getTitleString($fullname);
1033: $fullname - Fully qualified filename to check.

1039:
1.134 raeburn 1040: $r - Apache request object.
1041: $reqfile - File in request.
1042: $here - Where we are in directory tree.
1043: $dirname - Name of directory special file.
1044: $modtime - Encoded modification time.
1045: targetdir - Publication target directory.
1046: bombs - Reference to hash of URLs with runtime error messages.
1047: numdir - Reference to scalar used to track number of sub-directories
1048: in directory (used in form name for each "actions" dropdown).
