Re: [O] Org Mode TOOD two way sync tool

[Christopher J. White]

Hi Karra,

I've been working on org-toodledo.el to perform bi-directional sync of 
TODO items with the Toodledo server, and faced many of the same issues 
you raise about figuring out the exact format and grammar of a TODO item.

You may find looking at my source useful, either as inspiration, 
integration, or just understanding what fields are what.

The general approach was to build an object that represents a parsed 
TODO item, and fill that in from either the org-buffer TODO items, or 
from items retrieved from the server.  That object can then be compared 
to others (one from the server and one from the local buffer), converted 
to a new org TODO, sent to the server as a new TODO, etc.  The 
components of the TODO item are obviously targeted to what makes sense 
for Toodledo, but I think they are fairly generic.

You might also look at org-element.el which I recently learned about 
which may also help.  I have it on my TODO list to learn more about it 
to see if I can't refactor org-toodledo to leverage it.  It is more 
geared toward generic org items as opposed to specifically TODO items.
