Hi,
In latex export, sometimes I want to make sure a section starts in a new page.
It seems I should be able to add a hook to org-export-before-parsing-hook, so if it sees a section with :newpage: tag (for example), it adds #+LATEX: \newpage before the section header so I would get
\newpage
\section{Section Name}
in the exported file.
I have a couple of hooks already so in general I'm using the following code:
(org-map-entries
(lambda ()
(progn
))
"+newpage")
but I'm not sure how to add #+LATEX: \newpage before the section header - .
Best Regards,
Joon

So far I have done:
(defun org/parse-headings (backend)
(if (member backend '(latex))
(org-map-entries
(lambda ()
(progn
(insert-string "#+LATEX: \\newpage")
))
"+newpage")
)
)
(add-hook 'org-export-before-parsing-hook 'org/parse-headings)
This puts #+LATEX: \\newpage before the subheading, but the problem is if I try to do (insert-string "#+LATEX: \\newpage"), exporting gets stuck with the message "org-babel-exp process txt at position 280541...". I suspect inserting a string messes up the position. How would I insert string with the newline character before a heading?
Best,
Joon

See the doc for org-map-entries - it says:
,----
| The call to FUNC will be wrapped into a save-excursion form, so FUNC
| does not need to preserve point. After evaluation, the cursor will be
| moved to the end of the line (presumably of the headline of the
| processed entry) and search continues from there. Under some
| circumstances, this may not produce the wanted results. For example,
| if you have removed (e.g. archived) the current (sub)tree it could
| mean that the next entry will be skipped entirely. In such cases, you
| can specify the position from where search should continue by making
| FUNC set the variable ‘org-map-continue-from’ to the desired buffer
| position.
`----
So you'll have to manipulate org-map-continue-from appropriately.

I would think it would be easier to add at export time using
`org-export-filter-headline-functions'.

Thanks a lot! Adding (setq org-map-continue-from (outline-next-heading)) after insert-string seemed to solve the problem.
(I added "newpage" to org-tags-exclude-from-inheritance, so the newpage does not get applied to subheadings)
(defun org/parse-headings-latex-newpage (backend)
; add \newpage to headings with :newpage: tag
(if (member backend '(latex))
(org-map-entries
(lambda ()
(progn
(insert-string "#+LATEX: \\newpage\n")
(setq org-map-continue-from (outline-next-heading))
))
"+newpage"))
)
(add-hook 'org-export-before-parsing-hook 'org/parse-headings-latex-newpage)
(add-to-list 'org-tags-exclude-from-inheritance '"newpage")
Best,
Joon

I spoke too early - if I have two headings with :newpage: tag in a row, my current code below skips the second heading.
It seems (setq org-map-continue-from (outline-next-heading)) in my code is the problem .. any help will be appreciated!
(defun org/parse-headings-newpage (backend)
; add \newpage to headings with :newpage: tag
(if (member backend '(latex))
(org-map-entries
(lambda ()
(insert-string "#+LATEX: \\newpage\n")
(if (outline-next-heading)
(setq org-map-continue-from (outline-next-heading)))
)
"+newpage"))
)
(add-hook 'org-export-before-parsing-hook 'org/parse-headings-newpage)
