1108: =head1 INTRODUCTION
1109:
1110: This module publishes a directory of files.
1111:
1112: This is part of the LearningOnline Network with CAPA project
1113: described at http://www.lon-capa.org.
1114:
1115: =head1 HANDLER SUBROUTINE
1116:
1117: This routine is called by Apache and mod_perl.

1121: =item *
1122:
1123: read in information
1124:

1126:
1127: start page output
1128:
1129: =item *
1130:
1131: run through list of files and attempt to publish unhidden files

1136:
1137: =over
1138:
1139: =item startpage($r, $uame, $udom, $thisdisfn)
1140:
1141: Output the header of the page. This includes:
1142: - The HTML header
1143: - The H1/H3 stuff which includes the directory.
1144:
1145: startpage($r, $uame, $udom, $thisdisfn);
1146: $r - The apache request object.
1147: $uname - User name.
1148: $udom - Domain name the user is logged in under.
1149: $thisdisfn - Displayable version of the filename.
1150:
1151: =item getTitleString($fullname)
1152:
1153: Get the title string or "[untitled]" if the file has no title metadata:
1154: Without the latter substitution, it's impossible to examine metadata for
1155: untitled resources. Resources may be legitimately untitled, to prevent
1156: searches from locating them.
1157:
1158: $str = getTitleString($fullname);
1159: $fullname - Fully qualified filename to check.
1160:
1161: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
1162: $numdir)
1163:
1164: Put out a directory table row:
1165:
1166: $r - Apache request object.
1167: $reqfile - File in request.
1168: $here - Where we are in directory tree.
1169: $dirname - Name of directory special file.
1170: $modtime - Encoded modification time.
1171: targetdir - Publication target directory.
1172: bombs - Reference to hash of URLs with runtime error messages.
1173: numdir - Reference to scalar used to track number of sub-directories
1174: in directory (used in form name for each "actions" dropdown).
