Ist:

Ein Bot in Rails, welcher per Jabber Account neue Messages entgegen nimmt und an den Fridge sendet; Sollte eigentlich primär für den Twitterbot sein, damit man auch 'direct' messages an den Twitter Bot schicken kann, die dann angezeigt werden. Aber nachdem Twitter im Moment kein Jabber anbietet (Performance Probleme) ists nun mehr 'nur' ein Jabber Bot :) Benoetigt: ruby on rails, 'xmpp4r' gem (alles andere sollte schon da sein :));

Kann:

!help !last !last+time !events !sense !about !door !door+time


Will:

Ideen und Vorschläge was man(n) noch so reinbauen kann :)


Dankt:

Overflo, Wizard23, Marius für den Metafridge + Fin für die Twitteranbindung

Sushimako fürs Script-Hosting und seine Geduld, alle paar Stunden ne neue Version drauf zu tun :)

Diff:

Version 0.6: Added !door (Last 10 Metadoor Videos) and !door+time
Version 0.5: Added !about (About the Bot) and !events (For the Metalab Event list)
Version 0.4: /command wurde zu !command; Added !help und !sense
Version 0.3: Das Command '/last' gibt jetzt die letzten 10 Metafridge Nachrichten aus - '/last+time' ist mit Timestamp;
Version 0.2: Bot gibt jetzt ein 'Thanks!' zurueck + ich hab mein privates Jabber Icon raus :)
