Need help exporting subtrees to html

Need help exporting subtrees to html

[Juan Reyero]

Greetings,

I have written a function to export org-mode subtrees as jekyll posts,
http://juanreyero.com/open/org-jekyll/  The idea is that any entry in
an org-publish project that has a :blog: keyword and an :on: property
with a timestamp should be exported to a _posts directory with the
year-month-day-title.html that jekyll expects, with the properties as
front-matter.

I was very happy with it, until I realized that the levels of the
headers in the exported file (h2, h3, etc) depend on the indentation
of the subtree in the outline.  I wanted to be able to add a :blog:
subtree anywhere in my project's files, and get it always exported the
same, regardless of where in the outline it is.

Is there any reasonably simple way to overcome this problem?  I am using:

(org-narrow-to-subtree)
(setq html (org-export-as-html nil nil nil 'string t nil))

to do the exporting (all the code is in github,
http://github.com/juanre/org-jekyll).  In summary, what I need is an
org-export-as-html that treats the least indented outline as a
0-indentation.

Best,

Juan

Hi Juan,

Try this:

(outline-mark-subtree)
(setq html (org-export-as-html nil nil nil 'string t nil))

Thanks for your answer.  I've tried it, but now it exports the whole
buffer, as if (outline-mark-subtree) didn't understand which subtree I
am looking at.  I am doing this from within an (org-map-entries).  If
I first narrow and then mark it doesn't work either: it complains of
"Before first headline at position...".

I have updated the tests at http://github.com/juanre/org-jekyll to
reflect the problem.

Best,

Juan

You are right, this does not work as I had hoped.  What needs to be
done is that the tree must be selected, and the region needs to be  
*active*
when the export command is called.  I am not quite sure right now
how to do this in the middle of a Lisp program....

Looks like it is not going to be a small investment.  For the time
being I'll stick to writing blog posts as first-level entries, and
I'll try to figure it out when I find some more time.  Thank you very
much for your answers.

Cheers,

Juan

Hi,

If it helps, I've been doing something similar to support publishing
updates on the org-babel development -- using the code shown here [1]
under the "Development Updates" section.  This generates a files in
_posts for each subtree of of the "tasks" and "bugs" sections which have
a time-stamp in their properties.  It should be fairly straightforward
to adapt this code to export all properties as YAML frontmatter.

It is exactly what I did :-).  I found your code here [1], and adapted
it so that it would use files in an org-publish project and would
export properties.  So thank you very much for making it available.
It does, however, have the same problem I find: the header level with
which the piece is exported (h1, h2, etc) depends on the outline level
on which the item you export happened to be.  I was hoping to export
the chunks independently of where they were written.

I will share it with Worg as soon as I manage to make it work.

Best,

Juan

Ah, I should have read the thread more carefully :)

So this turned out to be somewhat tricky.  I was able to adjust my
previous code so that every subtree will be promoted to a top-level
heading before export by adding the following (this change can also be
seen in my published code here [1]).

--8<---------------cut here---------------start------------->8---
                (org-narrow-to-subtree)
                (let ((level (- (org-outline-level) 1))
                      (contents (buffer-substring (point-min) (point-max))))
                  (dotimes (n level nil) (org-promote-subtree))
                  (setq html (org-export-as-html nil nil nil 'string t nil))
                  (set-buffer org-buffer)
                  (delete-region (point-min) (point-max))
                  (insert contents)
                  (save-buffer))
                (widen)
--8<---------------cut here---------------end--------------->8---

Hope this helps. Cheers -- Eric

It works!  Thank you _very_ much.  I've just had to add a
org-reduced-level to the org-outline-level, like

(org-reduced-level (org-outline-level)).

I've updated it in github and on
http://juanreyero.com/open/org-jekyll/, and I'll try to add something
to worg this afternoon.

Best,

Juan
