    <p>I'm trying to make a Jabber bot and I am having trouble keeping it running while waiting for messages. How do I get my script to continuously run? I have tried calling a subroutine that has a while loop that I, in theory, have set up to check for any messages and react accordingly but my script isn't behaving that way.</p> <p>Here is my source: <a href="http://pastebin.com/03Habbvh" rel="nofollow noreferrer">http://pastebin.com/03Habbvh</a></p> <pre> # set jabber bot callbacks $jabberBot->SetMessageCallBacks(chat=>\&chat); $jabberBot->SetPresenceCallBacks(available=>\&welcome,unavailable=>\&killBot); $jabberBot->SetCallBacks(receive=>\&prnt,iq=>\&gotIQ); $jabberBot->PresenceSend(type=>"available"); $jabberBot->Process(1); sub welcome { print "Welcome!\n"; $jabberBot->MessageSend(to=>$jbrBoss->GetJID(),subject=>"",body=>"Hello There!",type=>"chat",priority=>10); &keepItGoing; } sub prnt { print $_[1]."\n"; } #$jabberBot->MessageSend(to=>$jbrBoss->GetJID(),subject=>"",body=>"Hello There! Global...",type=>"chat",priority=>10); #$jabberBot->Process(5); #&keepItGoing; sub chat { my ($sessionID,$msg) = @_; $dump->pl2xml($msg); if($msg->GetType() ne 'get' && $msg->GetType() ne 'set' && $msg->GetType() ne '') { my $jbrCmd = &trimSpaces($msg->GetBody()); my $dbQry = $dbh->prepare("SELECT command,acknowledgement FROM commands WHERE message = '".lc($jbrCmd)."'"); $dbQry->execute(); if($dbQry->rows() > 0 && $jbrCmd !~ /^insert/si) { my $ref = $dbQry->fetchrow_hashref(); $dbQry->finish(); $jabberBot->MessageSend(to=>$msg->GetFrom(),subject=>"",body=>$ref->{'acknowledgement'},type=>"chat",priority=>10); eval $ref->{'command'}; &keepItGoing; } else { $jabberBot->MessageSend(to=>$msg->GetFrom(),subject=>"",body=>"I didn't understand you!",type=>"chat",priority=>10); $dbQry->finish(); &keepItGoing; } } } sub gotIQ { print "iq\n"; } sub trimSpaces { my $string = $_[0]; $string =~ s/^\s+//; #remove leading spaces $string =~ s/\s+$//; #remove trailing spaces return $string; } sub keepItGoing { print "keepItGoing!\n"; my $proc = $jabberBot->Process(1); while(defined($proc) && $proc != 1) { $proc = $jabberBot->Process(1); } } sub killBot { print "killing\n"; $jabberBot->MessageSend(to=>$_[0]->GetFrom(),subject=>"",body=>"Logging Out!",type=>"chat",priority=>10); $jabberBot->Process(1); $jabberBot->Disconnect(); exit; } </pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
