After doing some plain text Google wave robots implementations, it is time for some fun robot that has some
graphical implementation to it. This post is about port of tricky python sample published by Google in
their Google wave development resources. This robot uses Google wave gadget as well to display some images. So
implementation of this robot will help you understand how Google wave gadgets get included in the wave and
how you can add them from robot itself. I am not going to discuss implementation of gadget here. I will do it
in my future post.
In one of my earlier posts
Developing Google Wave Robots Using .Net i discussed fundamental steps in creating and deploying your
Google wave robot. So I will refer you to reading that post if you have not done it already. So following those
steps i created my new robot named byteblocks-tricky.
How to use and try it
- Add byteblocks-tricky@appsot.com as participant in your contacts
- Start a new wave and add byteblocks-tricky@appspot.com as one of the participants in the
wave. As soon as you add it as participant, you will notice that title of your wave has changed
and a graphical widget gets added to the document.
- Start a new message and type trick or treat. It will randomly give your trick or treat
and display an image for the item.
Implementation
This robot handles WAVELET_SELF_ADDED and BLIP_SUBMITTED. In WAVELET_SELF_ADDED
handler, robot inserts a gadget into the wave. In BLIP_SUBMITTED the robot looks for text
trick or treat in document. If it finds it, it randomly decided if you are going to get tricked or
get a treat. Then it searches Google images for appropriate image for that item and then inserts that
image into the document.
Have fun with trick or treat.
