How can I make my Perl Jabber bot an event
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.
Here is my source: http://pastebin.com/03Habbvh
# 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 "iqn"; } 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 "killingn"; $jabberBot->MessageSend(to=>$_[0]->GetFrom(),subject=>"",body=>"Logging Out!",type=>"chat",priority=>10); $jabberBot->Process(1); $jabberBot->Disconnect(); exit; }
POE has some pretty good event frameworks. I don't know how good the one for Jabber (POE::Component::Jabber) is, but it's probably worth looking at.
AnyEvent :: XMPP是非常全面的,并且,因为它使用AnyEvent,可以在支持循环(AnyEvent自己的,Event,EV,Tk,Glib / Gtk,甚至是POE)的任何事件驱动的应用程序中运行。
I think you can make your example work by doing this:
0 while $jabber->Process
Having said that, I would strongly recommend using a proper Event handling framework such as AnyEvent (my personal favorite) or POE (the traditional choice).
