[bug] org block not correctly exported to LaTeX

[bug] org block not correctly exported to LaTeX

[Thomas Holst]

Hello,

when the follwing org-file is exported to LaTeX, #+BEGIN_ORG
and #+END_ORG is inserted in the tex-file.

--8<------------------------schnipp------------------------->8---
* Testing output perl to org

  #+srcname: TestingPerlToOrg
  #+begin_src perl :exports results :results output org
    print "Hello World\n";
  #+end_src

  #+results: TestingPerlToOrg
  #+BEGIN_ORG
  Hello World
  #+END_ORG
--8<------------------------schnapp------------------------->8---

Relevant part of the tex-file:
--8<------------------------schnipp------------------------->8---
#+begin_src latex
  \#+begin\_{}org 
    Hello World
  \#+end\_{}org
#+end_src
--8<------------------------schnapp------------------------->8---

If the #+BEGIN_ORG ... #+END_ORG starts at column 0 it is not inserted
into the tex-file. Other blocks (e.g. #+BEGIN_EXAMPLE ... #+END_EXAMPLE)
are not inserted if they are indented.

Tested with:
emacs 23.2.1 on WinXP
Org-mode version 7.6 (release_7.6.75.g67e9) (local patch to makefile)

Thanks again for org-mode. More and more of my collegues are starting to
use it!

You surely want

#+begin_src org
#+end_src org

"#+begin_org" doesn't exist.

Hi Bastien,

thanks for your answer.

#+BEGIN_ORG 
#+END_ORG

gets inserted by org-babel. Here is the relevant part of ob.el lines
1620 ff.

#+srcname: ob.el
#+begin_src emacs-lisp
  ;; ....
  ((member "org" result-params)
   (wrap "#+BEGIN_ORG" "#+END_ORG"))
  ;; ...
#+end_src emacs-lisp

Here is an example which shows the issue.

#+begin_src org
* Testing org-babel perl
  
  #+srcname: TestingPerl
  #+begin_src perl :exports results :results output org
    print("#+CAPTION: A caption\n");
    print("#+LABEL: tbl:dvi\n");
    print("#+ATTR_LaTeX: placement[H]\n");
    print("| *bold/T* |\n");
    print("|--------|\n");
    print("| normal |\n");
  #+end_src

  #+results: TestingPerl
  #+BEGIN_ORG
  #+CAPTION: A caption
  #+LABEL: tbl:dvi
  #+ATTR_LaTeX: placement[H]
  | *bold/T* |
  |--------|
  | normal |
  #+END_ORG
#+end_src org

I tested replacing 

 #+BEGIN_ORG 
 #+END_ORG 

with 

 #+BEGIN_SRC org
 #+END_SRC org

But that doesn't work. The org-babel output is inserted verbatim when
exported to LaTeX. That is not what is expected. 

I could use a

:results output raw

header, but with a long output (including blank lines) org-babel has
problems finding the end of the output when recalculating the source
block. The org-babel output gets appended not rewritten.

My workaround is not indenting the source block. Then everything works
as expected. But indented soure blocks look nicer.

Thanks again for looking into this.

Yes, Babel uses the #+begin/end_org as markers, so that it can identify
the beginning and end of raw Org-mode results when those results need to
be deleted or replaced with new results.

Since these are just used as markers and are functionally equivalent to
comment lines (e.g., no special treatment of the portion between the
begin_org and end_org lines) we didn't really coordinate this with the
results of Org-mode.

It seems however that since comments must start on the first character
of a line, these don't work when indented.

Would it be difficult to recognize these two lines as comments when they
are indented?  Note we also have #+begin/end_result lines which may
likely have similar issues.

Hi Thomas,

You have nested #+begin_src / #+end_src in this example.  I'm not sure
that is supported.

Fontification of this example seems to indicate that the
second #+begin_src perl is invalid and the first #+end_src terminates
the #+begin_src org

Hi Eric,

thanks for looking into this.

This exactly is the issue. If I remove the indentation from the result
block export works fine. As you mentioned #+begin/#+end_org markers are
treated as comments and do not appear in the LaTeX output.

I tried to find a solution to this but my lisp is not (yet) good enough.

I used #+begin_src / #+end_src org only to show the org file in my
email. The part between #+begin / #+end_src org is the content of my
test org file.

As Eric said the problem is #+begin_org / #+end_org which is inserted by
babel. If #+begin_org / #+end_org does not start at column 0 it appears in
the exported LaTeX file.
