1221: =head1 INTRODUCTION
1222:
1223: This module publishes a directory of files.
1224:
1225: This is part of the LearningOnline Network with CAPA project
1226: described at http://www.lon-capa.org.
1227:
1228: =head1 HANDLER SUBROUTINE
1229:
1230: This routine is called by Apache and mod_perl.

1234: =item *
1235:
1236: read in information
1237:

1239:
1240: start page output
1241:
1242: =item *
1243:
1244: run through list of files and attempt to publish unhidden files

1249:
1250: =over
1251:
1252: =item startpage($r, $uame, $udom, $thisdisfn)
1253:
1254: Output the header of the page. This includes:
1255: - The HTML header
1256: - The H1/H3 stuff which includes the directory.
1257:
1258: startpage($r, $uame, $udom, $thisdisfn);
1259: $r - The apache request object.
1260: $uname - User name.
1261: $udom - Domain name the user is logged in under.
1262: $thisdisfn - Displayable version of the filename.
1263:
1264: =item getTitleString($fullname)
1265:
1266: Get the title string or "[untitled]" if the file has no title metadata:
1267: Without the latter substitution, it's impossible to examine metadata for
1268: untitled resources. Resources may be legitimately untitled, to prevent
1269: searches from locating them.
1270:
1271: $str = getTitleString($fullname);
1272: $fullname - Fully qualified filename to check.
1273:
1274: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
1275: $numdir)
1276:
1277: Put out a directory table row:
1278:
1279: $r - Apache request object.
1280: $reqfile - File in request.
1281: $here - Where we are in directory tree.
1282: $dirname - Name of directory special file.
1283: $modtime - Encoded modification time.
1284: targetdir - Publication target directory.
1285: bombs - Reference to hash of URLs with runtime error messages.
1286: numdir - Reference to scalar used to track number of sub-directories
1287: in directory (used in form name for each "actions" dropdown).
