Google Wave for Developers: Making Robots Chris Patrick Con: Martin Sarsale November 17, 2009

Why build on Google Wave? Real-time == Real-awesome o Self-explanatory Workflow o Focused on bridging communication and workflow. Leverage o New and exciting technology and foundation. Opportunity! o New business opportunities.

Extensions in Wave Gadgets o Embed them in a conversation o Built with HTML+Javascript o Interactive with the Wave and it’s participants o Ex: maps, slideshows, search results Robots o Are actual participants of a Wave which can ‘do things’  Exactly the same as a Wave participant o Ex: content update, integration with other systems The most common ways to extend Wave are to use:

Wave Entities: Data Model Wave Wavelets Blips Documents “Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious.” Fred Brooks, The Mythical Man-Month

Robot Architecture Overview

Wave Robot Concepts Wave Robots... o Live in the cloud. o Are external (robotic) participants. o Have full access to wave. o Respond to events on a wave. o Are currently available for Java and Python APIs on Google App Engine.

Wave Robots Essentials APIs in Python and Java Runs in Google App Engine Events: o "Robot added to Wave" - WAVELET_SELF_ADDED o ”New blip" - BLIP_SUBMITTED o "Blip edited" - BLIP_VERSION_CHANGED o "New participant" - WAVELET_PARTICIPANTS_CHANGED Responds to: o Augmented or edited Wave content o Invites from other participants o Interaction with other systems outside of Wave

Robot Examples Smiley """Smiley: Yet another smiley robot.""" from waveapi import events from waveapi import robot def OnBlipSubmitted(properties, context): blip = context.GetBlipById(properties['blipId']) contents = blip.GetDocument().GetText() contents = contents.replace(':(', unichr(0x2639)) # happy contents = contents.replace(':)', unichr(0x263A)) # sad blip.GetDocument().SetText(contents) if __name__ == '__main__': smiley = robot.Robot('Smiley') smiley.RegisterHandler( events.BLIP_SUBMITTED, OnBlipSubmitted) smiley.Run() (A complete and useful robot in a single slide... with room to spare!)

Robot Roadmap New Robots wire protocol (v0.2) o Publish for community feedback o Implement Java and Python API parity Internal speed improvements for AppEngine robots. Robot Gateway / OpenSocial REST Access Robot access to OAuth controlled resources Better multiple wave access Sunset robot cron in favor of direct access to Wave servers. Gateway support: Improve the current tweety type of access to support outside addresses of the form
