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.

As of late February, 2008, SocialCalc implements all of the core spreadsheet functions.

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.
