[O] Get :PROPERTY: value from drawer in other heading during HTML export?

2014-09-12 Thread D. C. Toedt
When generating an HTML file from an org-mode document, I'd like to do a
GET operation to retrieve a property value from the drawer of an arbitrary
heading, using the CUSTOM_ID property to identify the heading.  From
Google-searching, I suspect that org-heading-components will be involved,
but I'm not proficient enough in elisp to be able to figure out how to use
it from the on-line examples I've found --- and I'm not proficient enough
in Emacs to use any built-in documentation about it (apropos doesn't
produce any results).

Here's an example, where GET-PROP is a macro I'd like to use:

==BEGIN==

#+MACRO: get-prop []

#+MACRO: get-title [omitted -- thanks to Nicolas Goaziou for the get-title
macro, at
https://lists.gnu.org/archive/html/emacs-orgmode/2014-02/msg00386.html]

* CLAUSES

** Affiliate status from voting control
  :PROPERTIES:
  :CUSTOM_ID: AffilDefn
  :CD-ID: AFFIL-VOTE
  :IMPORTANCE: Situational
  :PUSHBACK: Unlikely
  :END:

(a) One individual or organization (Person) is an {{{DEFN(Affiliate)}}}
of another Person if,  directly or indirectly via one or more
intermediaries, one of those Persons /controls/ (as defined in subdivision
(b) below), or is controlled by, or is under common control with, the other
Person.

(b) [other text omitted]


* CONTRACT TEMPLATES

** Nondisclosure Agreement

{{{GET-PROP(AffilDefn,CD-ID)}}}: {{{GET-TITLE(AffilDefn)}}} -- pushback
from the other side is {{{GET-PROP(AffilDefn,PUSHBACK)}}}.

# This should export to:
# AFFIL-VOTE: Affiliate status from voting control -- pushback from the
other side is: Unlikely.

==END==

Thanks in advance,

You can use the same macro, replacing

  (org-get-heading nil nil) 

with

  (org-entry-get (point) $2)

IOW,

  #+MACRO: GET-PROP (eval (or (save-excursion (ignore-errors (let 
((org-link-search-inhibit-query t)) (org-open-link-from-string [[#$1]]) 
(org-entry-get (point) $2 UNKNOWN VALUE))

Beautiful -- thanks!

Is there any documentation I can read to get a sense of how things work?
 I've done a little bit of browsing inside org.el and its comments, but
that seems like it's not the most effective way to get up to speed.
