SocialCalc

SocialCalc is a Javascript-based spreadsheet being developed as a Sugar activity by Dan Bricklin and Luke Closs for the XO, with help from SocialText among many others. See also notes on pyxpcom and other spreadsheets.

From a post by Luke to sugar on 2/22/2008:

Background:
Socialcalc is a HTML/JS based spreadsheet engine that Dan has
developed.  He asked me to help him with sugar packaging, and
integration with the journal and other XO specific features.  The
python/javascript integration necessary for this project may also be
generally useful for other projects.  I'm developing with this in mind.

Summary of tonight's progress:
I learned how to change the gecko security settings to allow a local
HTML file access to XPCOM.  This means that I can now easily pass
messages between python and javascript.

Next Steps
With this spike done, I next need to spike to learn how saving and
restoring data to/from the journal works, and then I can integrate
this with pyxpcom to save and load data from the journal into
javascript.  With this in place, we should be almost ready to write
the save/load feature for Socialcalc.

Details of tonight's progress:
ActiveState Komodo developer Todd Whiteman (pyxpcom expert) suggested
I look into the nsIObserver xpcom interface as a way of passing
messages back and forth between python and javascript.  So this was my
challenge for tonight.
