Dear list
I believe I have found a bug in the export of latex source blocks (to
HTML, ascii, etc) when ob-latex.el has been loaded.
In summary, setting the :exports argument as a header property fails
to override the default value in org-babel-default-header-args:latex
Please see the attached org file for a demonstration.
Cheers
Will

* Bug in export of LaTeX source blocks when =ob-latex= is loaded
+ Quote from http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html:
#+begin_quote
Note: The default value of the =:exports= header argument alters the expected behavior of Org-mode export to HTML and LaTeX. LaTeX code blocks will require an explicit =:exports= code header argument to export as described in the Org-mode manual.
#+end_quote
+ However, if you specify the =:exports code= argument as a header property then it doesn't work. The value of =org-babel-default-header-args:latex= is still in force.
+ It only works if you use a code block specific argument.
** Evaluate this first
#+begin_src emacs-lisp
(require 'ob-latex)
#+end_src
#+results:
: ob-latex
** LaTeX export fails with =exports= set as a header property
:PROPERTIES:
:exports: code
:END:
#+begin_src latex
This is never exported after \texttt{ob-latex} has been loaded
#+end_src
** LaTeX export works with =exports= set as a code block specific argument
#+begin_src latex :exports code
This is exported correctly
#+end_src
** A workaround is to explicitly redefine =org-babel-default-header-args:latex=
After evaluating the following, both source blocks will export successfully.
#+begin_src emacs-lisp
(setq org-babel-default-header-args:latex '((:results . "latex") (:exports . "code")))
#+end_src
#+results:
| (:results . latex) | (:exports . code) |
** Tested with the following setup
:PROPERTIES:
:exports: both
