Babel : python generate org source block with an extra comma before * characters

Babel : python generate org source block with an extra comma before * characters

[Roland DONAT]

Dear Orgmode community,

Thanks in advance to take some time to help me with my problem...

Here is what is making me very sad :

I have a python (python 3 interpreter) source block that I use to generate 
parts of a report written in Orgmode. Suppose we have this little example :

#+NAME: test
#+BEGIN_SRC python :results value org :session test

report = """*** header 1
My pretty report

*** header 2
Ah ah! With that stuff, I will increase my *productivity*!!!
"""

report
#+END_SRC

What I get is :
#+RESULTS: test
#+BEGIN_SRC org
,*** header 1
My pretty report

,*** header 2
Ah ah, with that stuff, I will increase my *productivity*!!!
#+END_SRC

My question : Why Orgmode adds the comma before the star character???

In the manual, I read some things about comma-escaping in Org source block 
so my intuition tells me that my problem has something to do with that but I 
wasn't able to solve it for now.

My configuration :
- Org 8.2.5h on Linux Mint 16. 
- Python 3

Any help would be much appreciated! Thanks.

Roland.

This is because this function was applied to the results

,----[ C-h f org-escape-code-in-region RET ]
| org-escape-code-in-region is an interactive compiled Lisp function in
| `org-src.el'.
| 
| (org-escape-code-in-region BEG END)
| 
| Escape lines between BEG and END.
| Escaping happens when a line starts with "*", "#+", ",*" or
| ",#+" by appending a comma to it.
| 
| [back]
`----

Not sure how to get rid of this, maybe via :results raw? I'm not aware
of a configuration variable for this, but it surely exists.

Thank you. It helps me much!

Based on your answer, I copy-paste the code of the function "org-escape-
code-in-region" in a source block in my org buffer and modify the code to 
prevent it from inserting the comma. It's a little bit dirty but it works.

Using the raw option produces a correct result but I need the generated code 
to be decorated with a drawer to automatically replace the result at each 
code execution.

To do so, I tried to use de "drawer" option. It gives me the good result 
with a drawer but then when I export my org buffer to latex, the drawers 
":RESULTS:" is also exported which is not cool...

Well, thanks again!

Roland.

Did you try header args ':exports code ' or ':exports none'?

Sorry for the late reply and thanks for your post.

Yes I did and it does't work since these options do exactly what they are 
supposed to. So :  
- :exports code just exports my python source code.
- :exports none exports nothing.

But unfortunately I realised that the "BEGIN_ORG" drawer was also exported 
which is not what I want.

So, I will create another post on that specific subject.

Cheers.
