Export each top level heading to separate file

Export each top level heading to separate file

[Ista Zahn]

Hi all,

I'm looking for a way to export each top-level heading to a separate
markdown file. Ideally I would like to have the exported files named
according to the heading. For example I would like this org file

-----------------------------------
* Section one
Section one text
* Section two
** Section two a
Section two text
* Section three
Section three text
-----------------------------------

To generate three files:

--- Section one.md ---
Section one text

-----------------------------------

--- Section two.md---
## Section two a

Section two text

-----------------------------------

--- Section three.md -
# Section three

Section three text

-----------------------------------

I suspect that the publishing framework might support this, but I've
thus far avoided it because it looks pretty complicated to set up.
Before I dive in I'd like to know if the publishing framework is the
correct place to look for this functionality or if there is an easier
way to do it.

Thanks,
Ista

I have a similar question regarding LaTeX export. How to export a 
heading (any heading, regardless of level) within a file to heading.tex 
instead of file.tex? So far the only solution I have cobbled together is 
to C-x C-f 'file.tex" and then C-x C-w "heading.tex" .  I then typeset 
heading.tex using TeXworks. Perhaps I should note that my exported 
heading is tagged so that the heading is ignored.

Use properties to set the export file name -- example:
   :PROPERTIES:
   :EXPORT_TITLE: Internet banking fraud
   :EXPORT_FILE_NAME: internet-fraud
   :EXPORT_AUTHOR: Alan L Tyree
   :Citation: (2011) 22 JBFLP 214
   :EXPORT_OPTIONS: num:nil toc:nil
   :END:

If I understood your question properly.

Cheers,
Alan

Thanks, gets me half the way there. Setting properties as you
described and exporting each sub-tree works properly. Now how can I do
this for all the top-level headings in a file?

Sorry, that's beyond my pay grade :-). I would also be interested in
knowing the answer.

Try this:


(org-map-entries
             (lambda ()
               (let ((level (nth 1 (org-heading-components)))
                     (title (nth 4 (org-heading-components))))
                 (if (= level 1)
                     (org-entry-put (point) ":EXPORT_FILE_NAME:" title))))
 nil nil)

It seems to do what you want.

Thank you. Using C-c C-e C-s l o now exports to a pdf file no problem.

Dear John,

Thank you thank you! Using your code as I template I managed to write
a function that does what I wanted:

(defun my-exp-headings-to-markdown ()
  "Export each top-level heading to markdown."
  (interactive)
  (org-map-entries
   (lambda ()
     (let ((level (nth 1 (org-heading-components)))
  (title (nth 4 (org-heading-components))))
       (if (= level 1)
  (org-entry-put (point) "EXPORT_FILE_NAME" title))
       (if (= level 1)
  (org-md-export-to-markdown nil 1 nil))))
   nil nil))

Note that I had to remove the ":" from the second argument to
"org-entry-put" to get it working properly on my system. Not sure if
that was a bug in your original example or not.

Best,
Ista

Re: Export each top level heading to separate file

[John Kitchin]

[-- Attachment #1: Type: text/plain, Size: 5621 bytes --]

hmm.. I don't know if it was a bug, I ran the code on my system before
sending it, and it worked for me ;) I am glad you figured it out on your
system.

you could avoid the double if statements like this:

(defun my-exp-headings-to-markdown ()
  "Export each top-level heading to markdown."
  (interactive)
  (org-map-entries
   (lambda ()
     (let ((level (nth 1 (org-heading-components)))
           (title (nth 4 (org-heading-components))))
       (when (= level 1)
         (org-entry-put (point) "EXPORT_FILE_NAME" title)
         (org-md-export-to-markdown nil 1 nil)))))
   nil nil))


The when macro is like an if macro, with no else body.
