Footnotes issue with LaTeX export

Footnotes issue with LaTeX export

[John Hendy]

I'm experiencing an issue similar to this one:
--- http://osdir.com/ml/emacs-orgmode-gnu/2011-10/msg00544.html

I have a paragraph in which I reference a dollar amount (preceded by "$").
Attempting to insert a footnote anywhere in that paragraph gets me the
error "Cannot insert a footnote here." Inserting one manually leaves the
text black vs. fontified in the typical link color. Export produces it as
the verbatim text ([fn:xx]) instead of converting it. Trying to escape the
$ sign with \ doesn't fix the issue. Inserting another $ re-activates the
footnote, but that will obviously convert my dollar amount to math font,
which isn't what I want.

Any suggestions?


Thanks,
John

Yes: Can you provide an ECM (Complete Minimal Example), and tell the
version of Org you're using?

Also, does M-: (org-inside-LaTeX-fragment-p) return coherent values
(that is nil when point isn't inside a LaTeX fragment) when evaluated
throughout the paragraph?

Sure. Here you are:

-- M-x org-version: Org-mode version 7.8.03 (release_7.8.03.61.g59df6)
-- Emacs: 23.3.1

-- Minimal example:

#+begin_src orgmode
* Header

Test paragraph where I insert a dollar amount of $100.

Test paragraph where I insert a dollar amount of \$100.

Test paragraph where I insert a dollar amount of 100.[fn:1]

* Footnotes

[fn:1] Successful; the first two give the error 'Cannot insert a footnote
here'
#+end_src

I don't necessarily understand the debugger (what constitutes a full set of
output), but it looks like I might be getting two outputs depending on
where I execute that function:

-- One:
  eval((org-inside-LaTeX-fragment p))
  eval-expression((org-inside-LaTeX-fragment p) nil)
  call-interactively(eval-expression nil nil)
  recursive-edit()
  byte-code("\306\x10 @\307=\203!

-- The other:
  eval((org-inside-LaTeX-fragment p))
  eval-expression((org-inside-LaTeX-fragment p) nil)
  call-interactively(eval-expression nil nil)

Thoughts?


Thanks,
John

Yes, that's what I thought: `org-inside-LaTeX-fragment-p' is the key.

`----

On purpose, Org won't insert a footnote inside a LaTeX fragment.  But,
in your example, it is fooled by the currency.

One workaround would be to remove "$" as a math delimiter from
`org-format-latex-options'.

How about another idea... would it be possible to remove "\$" as a math
delimiter? I *do* use $math$ a bit, at least in this document, and have
=TeX:t and LaTeX:t= in my options... thus, I'm very careful about prefixing
"\" to any instances of $ and %. Removing \$ as a math delimiter or making
"\" register as the "universal escape character" would also do the trick.

If I removed $ as you suggest, could I use \begin{math}/\end{math} inline?
I have quite a bit of inline math.


Thanks!
John

You can already use \(inline math\). I don't think there is
a need for extra syntax.

You can use \( ... \) for inline math.  Works well for me.

Ah. Neat. I was unaware of this. That should do it. I'd still kind of
prefer not to have to tweak around with stuff. Given that special
combinations of "\" + "char" are LaTeX specific, it would seem that a
natural combination would be to activate such combinations when LaTeX:t is
used in #+options.

Your solution will work for me for now.

Thanks for the assistance!
John
