template, position search

[Petro <x.piter@gmail.com>]

Hi list,

I am developing a template, which will enable me to group notes about
one article together. It is my first attempt of elisp programming and I
have some difficulties.
In the first version my plan if to bind notes to a file name. (Later when
I make it working I plan to combine it with ebib but there is a long way
to go.)

* Articles
** /home/article1.pdf
*** note1
*** note2
** /home/article2.pdf
*** note1
*** note2

I open a article1.pdf file in emacs, run org-capture command and choose the
following template:
------------------------------------------------------------------------
("a" "article note" entry (file+function "~/org/scientific_notes.org" find-create-article-note-location)
             "*** test %?\nEntered on %U\n" )
------------------------------------------------------------------------
The find-create-article-note-location function scans the org file for an
entry "** /home/article1.pdf" and moves cursor below it. If there is no such entry then it is
created. Bellow is my attempt to implement it.
I do not know how to send an article filename to the
find-create-article-note-location function.
Once executed it creates  this headline and places the note bellow it.
** /home/petro/org/scientific_notes.org
*** note1
I would appreciate a hint how to make this function aware of the pdf
file name.

Thanks
Petro
