 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.

 1228: =head1 HANDLER SUBROUTINE
 1229: 
 1230: This routine is called by Apache and mod_perl.
 1231:

 1233: 
 1234: =item *
 1235: 
 1236: read in information
 1237: 
 1238: =item *
 1239: 
 1240: start page output
 1241: 
 1242: =item *
 1243: 
 1244: run through list of files and attempt to publish unhidden files

 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).
