Hi there,
Org-mode integration is now working (or so I hope!)!
You can mark a headline so that when you change its todo status to “DONE” (or equivalent), a datapoint of 1 (or any other fixed value) is sent to Beeminder (with optional confirmation, in the form of asking for the comment instead of using a default one).
You can also mark a headline so that each time you clock it out, a datapoint equal to the time clocked (by default in minutes, other units may be used) is sent to Beeminder (with optional confirmation as above).
Both these may be enabled for trees, so that marking as DONE or clocking out on any subitem of the given item has the same effect.
Also, I’m planning to do a screencast showing how cool beeminding from Emacs is. Personally, I got to the point that I avoid beeminding from either the website or the Android client, since they are sooo uncomfortable.
As for the code itself, the next step is displaying details about a goal (including a few recent datapoints), and the possibility of editing/deleting datapoints.
Stay tuned
