Re: Define capture template with dynamic id target

[Darlan Cavalcante Moreira <darcamo@gmail.com>]

Thanks David,

I tried to follow your suggestion, but I found two problems (maybe because
I know little about lisp).

For instance, suppose I have a test.org file with the follow content
--8<---------------cut here---------------start------------->8---
* 2011
  Every headline has an ID, but I have omitted here for brevity
*** May
***** Sub-headline
      bla bla bla
*** June
***** Sub-headline
      bla bla bla
--8<---------------cut here---------------end--------------->8---

I want the capture process to add an entry to the Sub-headline of June. If
I just use the file+headline and specify "Sub-headline" then it will add to
the Sub-headline in May. That's why I tried using IDs in the first
place. Also, every month I create a new month headline with the
Sub-headline and the capture process should add an entry to that
instead. That is the reason I wanted to get the ID from a function, instead
of just writing it in the capture template.


As far as I understand if I use the file+function target then the function
must return the headline name, but how can I say that I want the
Sub-headline of June and not of May? [first problem]

I found an org-id-find function that returns something like
"(filename . characterPosition)". Therefore, If there is a way to specify a
position where org should start looking for the headline then I could use
that to go to the correct Sub-headline.


Also, the file+headline target will add the entry as a child of the
specified headline, but file+function seems to add the entry as a sibling
of the headline returned by the function. [second problem] Is this intended
behaviour or is it a bug?

Darlan
