Re: [O] viewing number of nested headlines
Hi François, This appears to implement a mechanism for putting overlays on headlines. If so, this seems useful and would be a nice contrib or core.

Re: [O] viewing number of nested headlines
Maybe you could point me in the right direction; somewhere in the code, org-mode must be aware of the number of nested headlines in order for show-branches and show-children to work. Or maybe it is not. In any case, I'd try and adapt the code to display a number indicating (1) position in the hierarchy; and (2) number of headlines at that / those position(s).

Or maybe it is not. It is not. Long story short: folding a headline works by adding a text overlay with the invisible property, and finding the end of the overlay works by finding another headline of the same level. So there is no nothing of jumping by N subtrees. Still, you can fetch the number of invisible headline in a folded subtree *afterwards* -- I assumed this is what François' code does.

This could end up in a minor mode or simply a feature that people could turn on and off. But beware of the efficiency: with many headlines, the folding features of Org combined with this feature could become quite slow. Apologies if the original message was poorly articulated. No problem, that's part of the game. Thanks, -- Bastien

Hi 42 (what's your other name?) John is my real first name. . . .

That said, it is my responsibility to check that website before responding to (some) of the messages that get forwarded to my e-mail address in a thread I started. Anyway, checking out some of the other solutions, since many were provided. Thanks for the technical background on how headlines work in the code. 2013/2/5 Bastien b...@altern.org Hi 42 (what's your other name?) 42 147 aeus...@gmail.com writes: Maybe you could point me in the right direction; somewhere in the code, org-mode must be aware of the number of nested headlines in order for show-branches and show-children to work.

[O] viewing number of nested headlines
Is there a way to see how many nested headlines there are within a higher-level headline (not necessarily top-level)?
