1216: =head1 INTRODUCTION
1217:
1218: This module publishes a directory of files.
1219:
1220: This is part of the LearningOnline Network with CAPA project
1221: described at http://www.lon-capa.org.
1222:
1223: =head1 HANDLER SUBROUTINE
1224:
1225: This routine is called by Apache and mod_perl.

1229: =item *
1230:
1231: read in information
1232:

1234:
1235: start page output
1236:
1237: =item *
1238:
1239: run through list of files and attempt to publish unhidden files

1245: =over
1246:
1247: =item startpage($r, $uame, $udom, $thisdisfn)
1248:
1249: Output the header of the page. This includes:
1250: - The HTML header
1251: - The H1/H3 stuff which includes the directory.
1252:
1253: startpage($r, $uame, $udom, $thisdisfn);
1254: $r - The apache request object.
1255: $uname - User name.
1256: $udom - Domain name the user is logged in under.
1257: $thisdisfn - Displayable version of the filename.
1258:
1259: =item getTitleString($fullname)
1260:
1261: Get the title string or "[untitled]" if the file has no title metadata:
1262: Without the latter substitution, it's impossible to examine metadata for
1263: untitled resources. Resources may be legitimately untitled, to prevent
1264: searches from locating them.
1265:
1266: $str = getTitleString($fullname);
1267: $fullname - Fully qualified filename to check.
1268:
1269: =item putdirectory($r, $base, $here, $dirname, $modtime, $targetdir, $bombs,
1270: $numdir)
1271:
1272: Put out a directory table row:
1273:
1274: $r - Apache request object.
1275: $reqfile - File in request.
1276: $here - Where we are in directory tree.
1277: $dirname - Name of directory special file.
1278: $modtime - Encoded modification time.
1279: targetdir - Publication target directory.
1280: bombs - Reference to hash of URLs with runtime error messages.
1281: numdir - Reference to scalar used to track number of sub-directories
1282: in directory (used in form name for each "actions" dropdown).
