I'm using Org-mode version 8.2.5f with Gnu Emacs 24.3 on a Macbook Air with
Mavericks. I'm using it to build building an annotated collection of
contract clauses that I'm releasing under a Creative Commons license (see
http://www.CommonDraft.org), which I hope to monetize with a book on
contract drafting and negotiation.
I've done a fair amount of Google searching and also searching within this
list. If the following isn't already implemented, I'd pay USD$100 (via
PayPal) to have that done to whoever implements it in an official org-mode
release, plus another USD$100 donation to the org-mode maintainer.
QUESTION: When org-mode headings are NUMBERED, and the file is exported to
HTML, is there any way to have org-mode include the TITLE, not just the
section number, of a cross-referenced section, along the lines of the LaTex
\nameref{} function? Here's an example:
==BEGIN EXAMPLE==
#+OPTIONS: H:7 TOC:nil @:t num:1 email:t author:t
* Introduction to Technology Contracts
:PROPERTIES:
:CUSTOM_ID: IntroTechContracts
:END:
Lorem ipsum etc. etc.
* Dangerous Clauses
:PROPERTIES:
:CUSTOM_ID: DangerousClauses
:END:
Lorem ipsum etc. etc. -- see Section [[#IntroTechContracts]].
==END EXAMPLE==
With numbering turned ON (#+OPTIONS: num:1), the link is exported to HTML
as: Section <a href="#IntroTechContracts">1</a>.
With numbering turned OFF (#+OPTIONS: num:nil), the link is exported to
HTML as: Section <a href="#IntroTechContracts">Introduction to Technology
Contracts</a>.
Using a macro, I'd like to be able to AUTOMATICALLY do the latter --- that
is, have the link text be the heading title --- even with numbering turned
ON, so that a macro such as {{{SECREF(IntroTechContracts)}}} would render
in HTML as, let's say: Section <a href="#IntroTechContracts">1</a>,
entitled "<a href="#IntroTechContracts">Introduction to Technology
Contracts</a>."
Is that currently doable?

That works -- please email me privately with where to send the $100 via
PayPal. Thanks!
(Org-mode maintainer [Bastien, still?], can you please let me know if /

I found a problem when trying this on a bigger file (my book file): If $1
(actually, #$1) is for a link target that doesn't exist, then org-mode goes
into its "No match - create this as a new heading? (y or n)" routine. That
causes the rest of the export to fail. It'd be better if get-title could
do the same thing org-mode does natively, that is, including the text of $1
as italics to indicate a non-existent link.
Example file below:
--8<---------------cut here---------------start------------->8---
#+MACRO: get-title (eval (save-excursion (org-open-link-from-string
"[[#$1]]") (org-get-heading nil nil)))
#+MACRO: SECREF [[#$1][{{{get-title($1)}}}]]

The following should work.
#+MACRO: get-title (eval (or (save-excursion (ignore-errors (let ((org-link-search-inhibit-query t)) (org-open-link-from-string "[[#$1]]") (org-get-heading nil nil)))) "/$1/"))

Excellent -- that seems to export just fine.
Interestingly, the export now generates the message, "Position saved to
mark ring, go back with C-c & ." I presume that comes from the
((org-link-search-inhibit-query t)) argument in the "let" function. It doesn't
seem to harm the export results.
One of these years I'll have to start poking around the Emacs-Lisp code to
try to puzzle out the workings of the functions being called, especially
org-get-heading
--- is there a comparable one (or arguments) to get the section number of a
heading?
Many thanks, Nicolas.

There is `org-export-get-headline-number' but is only accessible during
export, so it cannot be called from a macro or a Babel block.
Anyway, in your case, you just need to use [[#custom-id]].

I think the whole thread calls for a variable to let the user
configure the way she wants references to be inserted.
Because \nameref could be useful in LaTeX/Beamer too.
And maybe ODT could enjoy such a function too.
Nicolas, what do you think?

Internal links in Beamer are complicated, because there's no way to know
which slide we're referring to. So I don't think \nameref would help
here.

This is something that cannot be easily achieved with filters, so it
could make sense to have a defcustom, or maybe two (one when headlines
are numbered and another one when they are not).
Anyway, patches welcome.

I'm not Org's maintainer anymore, I'm just /de facto/ taking decisions
in accordance with the other core maintainers, our level of trust lets
us move forward happily.
To come back to you original question:
,----
| #+OPTIONS: H:7 TOC:nil @:t num:1 email:t author:t
|
| * Introduction to Technology Contracts
| :PROPERTIES:
| :CUSTOM_ID: IntroTechContracts
| :END:
|
| Lorem ipsum etc. etc.
|
| * Dangerous Clauses
| :PROPERTIES:
| :CUSTOM_ID: DangerousClauses
| :END:
|
| Lorem ipsum etc. etc. -- see Section [[#IntroTechContracts]].
`----
Why don't you use
[[#IntroTechContracts][Introduction to Technology Contracts]]
as a link? It is the link stored by org-store-link, and later
inserted by org-insert-link, and AFAICS it is correctly exported.
But it's true there are a few things we can make more consistent
in this area though, so thanks for bringing this up.
Best,

I routinely tweak the text of the target headings as I edit the document.
For example, the section heading "Introduction to Technology Contracts"
might become, say, "Introduction: Why Technology Contracts are Fun."
I don't want to have to manually revise the link text for the many internal
cross-reference links that exist in the document. I'd really like to have
a way for a link to automatically retrieve the heading text during HTML
export.
