Broken LaTeX export

Broken LaTeX export

[SW]

I'm working on a large document in org-mode which I export to LaTeX. At present,
the outline/structure of the document has been created, but not much of the
content. The LaTeX export has strange pagination, a blank page and text that
runs off the page. Where can I paste/post this example?

If you don't mind making it public, I'd say go ahead and post the org
file (and any relevant customizations) here.

"M-x replace-regex <RET> \w+ <RET> Text <RET>"

I replaced all words with "Text". Here is the document outline. The breakage
happens from page 3 onwards. I export to LaTeX from org-mode 7.8.06 in Emacs
23.2.1 and then compile to PDF with pdflatex twice.

Interesting: it seems to be a latex bug of some sort, but I haven't had
time to play with it too much yet. I'm trying things like modifying the
tex file slightly and seeing if the empty page(s)/overfull page(s)
persist.  So far, it seems that all the packages that org includes are
innocent: I took them all out and the strangeness persists.

Thanks for the details. I noticed the overfull warnings from pdflatex.
Smaller/simpler test cases I tried exported to LaTeX perfectly.

FWIW:

$ pdflatex --version

I shortened the document by moving "\end{document}" around to try to find the
problem. In some cases, the document rendered correctly. I think this is related
to having to many "section" type headings in LaTeX with no content.

To test this, I added:

\usepackage[english]{babel}
\usepackage{blindtext}

And then used "M-x replace-string" to replace "\subs" with "\blindtext^q^j\subs"
to enter a lots of text into the document. It now renders correctly, with the
end of the document back to where it should be.

However, this is a work-around, not a solution, as part of the appeal of
org-mode and the LaTeX export is to be able to work with and generate outlines
and structures of documents first, before adding all the content.

Posted as a question here:

http://tex.stackexchange.com/questions/57857/overfull-box-and-broken-pagination

with two answers so far, both of them useful I think.

LaTeX tries very hard not to break pages around headings.  It expects
you to tell it when it is OK to not obey that rule, but you never did.
The correct way of dealing with a file that consists only of headings is
to write your own style file and explicitly allow page breaks in the
sectioning commands (usually before the heading).  While you're doing
that you can also chose a more suitable formatting.

A simple solution which keeps your interest in the outline structure at
this stage of the writing is to add the line

#+options: H:3

to the document (remembering to refresh org by typing C-c C-c on this
line).  This converts all 4th level headings and lower to lists on
export without you having to change the document content at all.

For your test document, this works just fine.

Once you have added enough text, you can change the 3 to 5 and your
document should export just fine.

HTH,
eric

Thanks. That's a useful suggestion.
