[BUG][Babel] Exporting text before heading

[BUG][Babel] Exporting text before heading

[Nicolas Goaziou]

Hello,

I can't export the following file, would it be to latex or html.

-----
#+TITLE: Title

  - First element

    #+BEGIN_SRC org
    ,- one
    ,- two
    #+END_SRC

    1. sub-item

       #+BEGIN_EXAMPLE
       Line 1
       Line 2
       #+END_EXAMPLE

    2. another sub-item

  - Another element
-----

If I remove one of the blocks, I can export again to latex or html.
Same thing if I add an heading between the title and the first
element.

If I only add plain text before the first element, or an heading after
the list, it won't work.

I tried to bisect but it appears this org file had never been exported
successfully to html and stopped getting exported successfully to
latex since the following commit:

-----

Keep BABEL meta lines in tact

* lisp/org-latex.el (org-export-latex-first-lines): Do not mark
  meta lines for removal. Do not remove BABEL config lines during export
-----

Because of this, I tend to think it is babel related, even though
removing only the example block also solves the problem.

Config is minimal, so all variables should be at default value, and
the last lines in *Message* buffer are :

-----
Exporting...
org-babel-exp processing...
setf: Wrong type argument: consp, nil
-----

Regards,

Hi Nicolas,

I was able to export your example to html without any problems, however
I did receive the same error you mentioned when exporting to LaTeX.

The attached patch fixes the LaTeX export on my system, please give it a
try and let me know if it works for you.  I'm going to look into this a
little bit more, as it seems that for LaTeX export the "#+begin_src org"
block is being processed /twice/ by org-exp (probably due to the LaTeX
exports mechanism for first exporting the header of a file and then
exporting the body), which is not desirable and could be the root issue
which this patch may just paper over.

Cheers -- Eric

HTML problem was indeed from my side.
