Export subtrees of level n

Export subtrees of level n

[Michael Welle]

Hello,

imagine the following document structure:

* talk1
* talk2
** foo
** bar
** foobaz


Now the point is in section foobaz and I want to export the subtree
talk2. C-c C-e C-s doesn't do exactly what I want. I can move the point
up to * talk2, export the subtree and then move the point back.

Is there an existing way to say that I want to go up to a level n
heading and then export, or do I have to implement that by myself?

Regards
hmw

Note that subsequent C-u C-c C-e will re-use the same subtree.

The latter, if you want to have this right from the start (and not from
the second call)

I think you'll have to do it yourself.  Here are a couple of ideas:

1.  Write a function to export a subtree with a specific Org ID.

2.  Write a function to look up the tree from point and export the first
subtree with a certain property.

ah, learned something new here.

I think, I will stick with this, because even if I use C-u C-c C-e I
will forget to move up to the right heading the first time I use it ;).

I thought about implementing the second approach. I have slides for
several talks in the same org file. Since I mostly need this
functionality when I'm developing slides, just going up from point until
reaching the desired heading is easy to implement.

If you can implement this, that would be great as I find myself doing this all the time as well. Currently what I do is make sure to export the right subtree first, and then start using "\C-u\C-c\C-e". I bind f5 to "\C-u\C-c\C-e" with the following in my init file:

(fset 'export-last-subtree
      "\C-u\C-c\C-e")

(eval-after-load "org"
  '(progn
     (define-key org-mode-map (kbd "<f5>") 'export-last-subtree)))

I use this ad hoc implementation:


(defun hmw/org-export (&optional level)
  "Go up to a section of level `level', if there is any, and then call `org-export-dispatch'. `level' defaults to 1."
  (interactive)
  (unless level (setq level 1))
  (save-excursion
  (while (< level (or (org-up-heading-safe) -1)))
  (if (org-at-heading-p)
      (org-export-dispatch))))


That hack could be optimised, but works for me ;).
