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: A message the recipient B -acknowlegde receipt of before they are allowed to continue using the -system, preventing a user from claiming they never got a message - -=item * B: 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: 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: LON-CAPA can block display of e-mails that are -sent to a student 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 screen, but generally, LON-CAPA messages -are much more useful then traditional email can be made to be, even -with HTML support. +lonmsg provides routines for sending messages. 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 $uname and +$udom in stored internal messages, compared +with $email in stored +Domain Coordinator e-mail for the storage of information about +recipients of the message/e-mail. + =head1 FUNCTIONS =over 4 @@ -104,27 +60,25 @@ since lonmsg already implements that fun =cut use strict; -use Apache::lonnet(); -use vars qw($msgcount); +use Apache::lonnet; use HTML::TokeParser(); -use Apache::Constants qw(:common); -use Apache::loncommon(); -use Apache::lontexconvert(); -use HTML::Entities(); -use Mail::Send; use Apache::lonlocal; -use Apache::loncommunicate; +use Mail::Send; +use LONCAPA qw(:DEFAULT :match); -# Querystring component with sorting type -my $sqs; -my $startdis; -my $interdis; +{ + my $uniq; + sub get_uniq { + $uniq++; + return $uniq; + } +} # ===================================================================== Package sub packagemsg { my ($subject,$message,$citation,$baseurl,$attachmenturl, - $recuser,$recdomain)=@_; + $recuser,$recdomain,$msgid,$type,$crsmsgid,$symb,$error)=@_; $message =&HTML::Entities::encode($message,'<>&"'); $citation=&HTML::Entities::encode($citation,'<>&"'); $subject =&HTML::Entities::encode($subject,'<>&"'); @@ -134,34 +88,74 @@ sub packagemsg { #remove machine specification $attachmenturl =~ s|^http://[^/]+/|/|; $attachmenturl =&HTML::Entities::encode($attachmenturl,'<>&"'); - + my $course_context; + if (defined($env{'form.replyid'})) { + my ($sendtime,$shortsubj,$fromname,$fromdomain,$count,$origcid)= + split(/\:/,&unescape($env{'form.replyid'})); + $course_context = $origcid; + } + foreach my $key (keys(%env)) { + if ($key=~/^form\.(rep)?rec\_(.*)$/) { + my ($sendtime,$shortsubj,$fromname,$fromdomain,$count,$origcid) = + split(/\:/,&unescape($2)); + $course_context = $origcid; + last; + } + } + unless(defined($course_context)) { + $course_context = $env{'request.course.id'}; + } my $now=time; - $msgcount++; - my $partsubj=$subject; - $partsubj=&Apache::lonnet::escape($partsubj); - my $msgid=&Apache::lonnet::escape( - $now.':'.$partsubj.':'.$ENV{'user.name'}.':'. - $ENV{'user.domain'}.':'.$msgcount.':'.$$); - my $result=''.$ENV{'user.name'}.''. - ''.$ENV{'user.domain'}.''. + my $msgcount = &get_uniq(); + unless(defined($msgid)) { + $msgid = &buildmsgid($now,$subject,$env{'user.name'},$env{'user.domain'}, + $msgcount,$course_context,$symb,$error,$$); + } + my $result = ''.$env{'user.name'}.''. + ''.$env{'user.domain'}.''.
