=head1 INTRODUCTION |
|
|
|
This module publishes a directory of files. |
|
|
|
This is part of the LearningOnline Network with CAPA project |
|
described at http://www.lon-capa.org. |
|
|
|
=head1 HANDLER SUBROUTINE |
|
|
|
This routine is called by Apache and mod_perl. |

|
=head2 subroutines: |
|
|
|
=head3 startpage($r, $uame, $udom, $thisdisfn) |
|
|
|
Output the header of the page. This includes: |
|
- The HTML header |
|
- The H1/H3 stuff which includes the directory. |
|
|
|
startpage($r, $uame, $udom, $thisdisfn); |
|
$r - The apache request object. |
|
$uname - User name. |
|
$udom - Domain name the user is logged in under. |
|
$thisdisfn - Displayable version of the filename. |
|
|
|
=head3 getTitleString($fullname) |
|
|
|
Get the title string or "[untitled]" if the file has no title metadata: |
|
Without the latter substitution, it's impossible to examine metadata for |
|
untitled resources. Resources may be legitimately untitled, to prevent |
|
searches from locating them. |
|
|
|
$str = getTitleString($fullname); |
|
$fullname - Fully qualified filename to check. |
|
|
|
=head3 putdirectory(r, base, here, dirname, modtime) |
|
|
|
Put out a directory table row: |
|
|
|
putdirectory($r, $base, $here, $dirname, $modtime) |
|
$r - Apache request object. |
|
$reqfile - File in request. |
|
$here - Where we are in directory tree. |
|
$dirname - Name of directory special file. |
|
$modtime - Encoded modification time. |
|
|
|
=head3 CategorizeFiles($location, $files) |
|
|
|
Categorize files in the directory. |
|
For each file in a list of files in a file directory, |
|
the file categorized as one of: |
|
- directory |
|
- sequence |
|
- problem |
|
- Other resource. |
|
|
|
For each file the modification date is determined as well. |
|
Returned is a list of sublists: |
|
(directories, sequences, problems, other) |
|
each of the sublists contains entries of the following form (sorted by filename): |
|
(filename, typecode, lastmodtime) |
|
|
|
$list = CategorizeFiles($location, $files) |
|
$location - Directory in which the files live (relative to our execution) |
|
$files - list of files. |
