Greetings Orgs

When exporting an .org file to LaTeX, no line breaks are inserted into
the LaTeX source code. With default options from a fresh install, the
LaTeX code will not compile, because documentclass information appears
on the first line of the LaTeX source, which is a comment:

% Created 2012-06-08 Fri 12:58 \documentclass{article} [...]

As an experiment, I changed the the time stamp in org-latex.el from

      (format-time-string "%% Created %Y-%m-%d %a %H:%M\n"))

to

      (format-time-string "%% Created %Y-%m-%d %a %H:%M\r"))

and it appears that pdflatex recognizes this "\r" as a line break and hence
compiles. So the problem seems to be the way the "\n" is written (or not
written) to the LaTeX source file. Which is beyond me.

This doesn't happen to me.  Have you tried with "emacs -Q" to ensure
that it's not something in your configuration?

Hi Eric

Thanks! No, I hadn't thought of that, silly me.

It turns out that the following line in my .emacs caused the problems:

(add-hook 'LaTeX-mode-hook 'longlines-mode)

So now I have commented that one out and the export works fine and has 
all the line breaks I had expected. I guess I will just enable longlines 
mode manually when editing LaTeX from now on.

Thanks again for the pointer!

Cheers

Uffe

Interesting.  I do not understand why longlines-mode should cause this
problem.  However, this mode has always had quirky behaviour.

You may wish to use visual-line-mode instead which works similar to
longlines-mode but better, IMO.
