Hi all,
One of the things I really like about org-mode is the ability to quickly
move material between projects. For instance, I sometimes write material as
a conference paper and want to use some sections in my thesis. I also like
to keep a file with old chapter drafts for later reference (I could just
use git for this, but keeping an old-drafts file around makes some jobs
more convenient). One issue that I am running into is that when I move
material with org-refile, footnotes defined in the Footnote section do not
move with it. Additionally, if I try to export a subtree as an org buffer,
it does not take footnote definitions with it.
The obvious workaround for both problems is to define footnotes inline.
Another option (the one that I am using currently) is to set
org-footnote-section to nil, and to set org-footnote-auto-label to 'random.
This way footnotes are kept at the bottom of the section, so they move with
refile, and they have randomly generated names, so they won't conflict with
any footnote definitions in the destination file.
This solution works, but I wondered if there was any way to get org-refile
and org-export-org to take footnotes definitions with them, wherever they
are located.
With org-export-org, this seems especially important as backends are
supposed to faithfully export footnotes with their definitions.
Additionally, is there a way to easily convert numbered footnotes to
randomly named footnotes?
Thanks,
Leonard

This particular point should now be fixed. Thank you for reporting it.

Hi Leonard,
from the master branch, you can now use
`org-footnote-inline-footnotes' to convert external footnotes into
inline ones.
This is also accessible from the `C-c C-x f' menu that gets displayed
when calling `C-c C-x f' from a location where no sensible footnote
action can be done, or from `C-u C-c C-x f', which forces the display
of this menu.
As for converting numbered footnotes into random ones, yes, this
should be feasible -- hopefully someone can provide this hack and
add it to worg/org-hacks.org.
Thanks,

You didn't ask for it, but here are a few comments about it anyway ;)
(concat org-footnote-re "\\]")
will fail for numbered footnotes, since the regexp already contains the
closing bracket for this case. I suggest to use:
(while (re-search-forward org-footnote-re nil t)
(let ((context (save-excursion (backward-char) (org-element-context))))
(when (and (eq (org-element-type context) 'footnote-reference)
(eq (org-element-property :type context) 'standard))
...)))
Also, as a rule of thumb,
(car (org-element-at-point)) => (org-element-type (org-element-at-point))
Indeed, `car' relies on the internal representation of the object, which
might change. Public interface is less likely to do so.
You don't need to use `org-forward-element' since you called
`org-element-at-point', which will give you all the information needed,
which is probably (org-element-property :end element).
You should check if `org-footnote-section' is not nil before trying to
remove it.
Eventually, you should note that this process is bound to fail in some
situations, as footnote definitions can contain way more objects than
inline ones (e.g., lists, tables, multiple paragraphs ...). Worse, it
will break the current document when attempting to do so since footnote
definitions can contain blank lines.
All in all, I'm not convinced this should be a function provided in Org.

Sure ! I unconsciously asked, I guess.

Okay. Still, it's useful to have it *somewhere*. If you have a
moment, could you revert the commit, rewrite the function with the
suggested enhancements and add it to worg/org-hacks.org?
If you don't want to clean my dirt after me that's okay, I will
do so later on.
Thanks,
PS: I think it's useful to trigger the org-footnote-action menu
when org-footnote-new cannot do anything useful.

Sure, I will add it back later today, unless you're faster than me.

Wow, thanks! I didn't expect this to be that long...
I tested it with various input files and it works fine.

No hurry. I won't be connected later today.
Thanks a lot!

It could probably be refactored to gain a few lines of code. However it
has to deal with a few corner cases so there is no simple solution.

Done. Though, I changed `org-footnote-action' instead of
`org-footnote-new', since the latter should, IMO, return an error when
called from a point where no footnote is allowed.
