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. + +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. + +=head1 FUNCTIONS + +=over 4 + +=cut + use strict; use Apache::lonnet(); use vars qw($msgcount); -use HTML::TokeParser; +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; + +# Querystring component with sorting type +my $sqs; +my $startdis; +my $interdis; # ===================================================================== Package sub packagemsg { - my ($subject,$message,$citation)=@_; - $message=~s/\/\>\;/g; - $citation=~s/\/\>\;/g; - $subject=~s/\/\>\;/g; + my ($subject,$message,$citation,$baseurl,$attachmenturl, + $recuser,$recdomain)=@_; + $message =&HTML::Entities::encode($message,'<>&"'); + $citation=&HTML::Entities::encode($citation,'<>&"'); + $subject =&HTML::Entities::encode($subject,'<>&"'); + #remove machine specification + $baseurl =~ s|^http://[^/]+/|/|; + $baseurl =&HTML::Entities::encode($baseurl,'<>&"'); + #remove machine specification + $attachmenturl =~ s|^http://[^/]+/|/|; + $attachmenturl =&HTML::Entities::encode($attachmenturl,'<>&"'); + my $now=time; $msgcount++; my $partsubj=$subject; @@ -67,11 +142,10 @@ sub packagemsg { my $msgid=&Apache::lonnet::escape( $now.':'.$partsubj.':'.$ENV{'user.name'}.':'. $ENV{'user.domain'}.':'.$msgcount.':'.$$); - return $msgid, - ''.$ENV{'user.name'}.''. + my $result=''.$ENV{'user.name'}.''.
