LON-CAPA implements its own messaging system, rather then building on top of email, because of the features LON-CAPA messages can offer that conventional e-mail can not: =over 4 =item * B<Critical messages>: A message the recipient B<must> acknowlegde receipt of before they are allowed to continue using the system, preventing a user from claiming they never got a message =item * B<Receipts>: LON-CAPA can reliably send reciepts informing the sender that it has been read; again, useful for preventing students from claiming they did not see a message. (While conventional e-mail has some reciept support, it's sporadic, e-mail client-specific, and generally the receiver can opt to not send one, making it useless in this case.) =item * B<Context>: LON-CAPA knows about the sender, such as where they are in a course. When a student mails an instructor asking for help on the problem, the instructor receives not just the student's question, but all submissions the student has made up to that point, the user's rendering of the problem, and the complete view the student saw of the resource, including discussion up to that point. Finally, the instructor is reading all of this inside of LON-CAPA, not their email program, so they have full access to LON-CAPA's grading interface, or other features they may wish to use in response to the student's query. =item * B<Blocking>: LON-CAPA can block selected communication features for students during an online exam. A course coordinator or instructor can set an open and close date/time for scheduled online exams in a course. If a user uses the LON-CAPA internal messaging system to display e-mails during the scheduled blocking event, display of all e-mail sent during the blocking period will be suppressed, and a message of explanation, including details of the currently active blocking periods will be displayed instead. A user who has a course coordinator or instructor role in a course will be unaffected by any blocking periods for the course, unless the user also has a student role in the course, AND has selected the student role. =back Users can ask LON-CAPA to forward messages to conventional e-mail addresses on their B<PREF> screen, but generally, LON-CAPA messages are much more useful than traditional email can be made to be, even with HTML support. Right now, this document will cover just how to send a message, since it is likely you will not need to programmatically read messages, since lonmsg already implements that functionality. The routines used to package messages and unpackage messages are not only used by lonmsg when creating/extracting messages for LON-CAPA's internal messaging system, but also by lonnotify.pm which is available for use by Domain Coordinators to broadcast standard e-mail to specified users in their domain. The XML packaging used in the two cases is very similar. The differences are the use of <recuser>$uname</recuser> and <recdomain>$udom</recdomain> in stored internal messages, compared with <recipient username="$uname:$udom">$email</recipient> in stored Domain Coordinator e-mail for the storage of information about recipients of the message/e-mail. =head1 FUNCTIONS =over 4 =cut use strict; use Apache::lonnet; use HTML::TokeParser(); use Apache::Constants qw(:common); use Apache::loncommon(); use Apache::lontexconvert(); use HTML::Entities(); use Apache::lonlocal; use Apache::loncommunicate; use Apache::lonfeedback; use Apache::lonrss(); use Apache::lonselstudent(); use lib '/home/httpd/lib/perl/'; use LONCAPA; # Querystring component with sorting type my $sqs; my $startdis; my $interdis; # ============================================================ List all folders sub folderlist { my $folder=shift; my %lt = &Apache::lonlocal::texthash( actn => 'Action', fold => 'Folder', show => 'Show', go => 'Go', nnff => 'New Name for Folder', newn => 'New Name', thfm => 'The folder may not be renamed', fmnb => 'folder may not be renamed as it is a folder provided by the system.', asth => 'as this name is already in use for a system-provided or user-defined folder.', the => 'The', tnfm => 'The new folder may not be named', ); my %actions = &Apache::lonlocal::texthash( view => 'View Folder', rename => 'Rename Folder', delete => 'Delete Folder', ); $actions{'select_form_order'} = ['view','rename','delete']; my %permfolders = &get_permanent_folders(); my $permlist = join("','",sort(keys(%permfolders))); my ($permlistkeys,$permlistvals); foreach my $key (sort(keys(%permfolders))) { $permlistvals .= $permfolders{$key}."','"; $permlistkeys .= $key."','"; } $permlistvals =~ s/','$//; $permlistkeys =~ s/','$//; my %gotfolders = &Apache::lonmsg::get_user_folders(); my %userfolders; foreach my $key (keys(%gotfolders)) { $key =~ s/(['"])/\$1/g; $userfolders{$key} = $key; } my @userorder = sort(keys(%userfolders)); my %formhash = (%permfolders,%userfolders); my $folderlist = join("','",@userorder); $folderlist .= "','".$permlistvals; $formhash{'select_form_order'} = ['','critical','new',@userorder,'sent','trash']; my $output = qq|<script type="text/javascript"> function folder_choice(targetform,caller) { var permfolders_keys = new Array('$permlistkeys'); var permfolders_vals = new Array('$permlistvals'); var allfolders = new Array('$folderlist'); if (caller == 'change') { if (targetform.folderaction.options[targetform.folderaction.selectedIndex].value == 'rename') { for (var i=0; i<permfolders_keys.length; i++) { if (permfolders_keys[i] == targetform.folder.value) { alert("$lt{'the'} '"+permfolders_vals[i]+"' $lt{'fmnb'}"); return; } } var foldername=prompt('$lt{'nnff'}','$lt{'newn'}'); if (foldername) { targetform.renamed.value=foldername; for (var i=0; i<allfolders.length; i++) { if (allfolders[i] == foldername) { alert("$lt{'thfm'} '"+foldername+"' $lt{'asth'}"); return; } } targetform.submit(); } } else { targetform.submit(); } } if (caller == 'new') { var newname=targetform.newfolder.value; if (newname) { for (var i=0; i<allfolders.length; i++) { if (allfolders[i] == newname) { alert("$lt{'tnfm'} '"+newname+"' $lt{'asth'}"); return; } } targetform.submit(); } } } </script>|; $output .= ' <form method="post" action="/adm/email" name="folderlist"> <table border="0" cellspacing="2" cellpadding="2"> <tr> <td align="left"> <table border="0" cellspacing="2" cellpadding="2"> <tr> <td align="center"><b>'.$lt{'fold'}.'</b><br />'."\n". &Apache::loncommon::select_form($folder,'folder',%formhash).' </td> <td align="center"><b>'.$lt{'show'}.'</b><br /> <select name="interdis">'. join("\n",map { '<option value="'.$_.'"'.
