[babel] Silent output in Org, but verbose export

[babel] Silent output in Org, but verbose export

[Sebastien Vauban]

Hi Eric,

Currently, the following does not seem possible:

#+begin_src sh :results silent :exports results
echo "I want to see this in HTML/PDF, but not in Org"
#+end_src

Is there a way to do so?  That is:
- have no results inserted in the Org file
- well inserted when exporting the Org file

Best regards,
  Seb

Hi Seb,

While this functionality isn't explicitly built into Org-mode the
following should work...

#+begin_src sh :results (if org-current-export-file "replace" "silent") :exports both
  echo  "I want to see this in HTML/PDF, but not in Org"
#+end_src

Without adding to many header  arguments, I think an additional value for
the handling header argument ":results" would be useful: export_only, which,
would implement this behaviour.

Cheers,

Rainer

This works perfectly, thanks a lot!

Now, subquestion: let's suppose I first write this code block...

#+begin_src sh :exports results
echo "I want to see this in HTML/PDF, but not in Org"
#+end_src

#+results:
| I want to see this in HTML/PDF | but not in Org |

then I add the option "silent", and eval it:

#+begin_src sh :results silent :exports results
echo "I want to see this in HTML/PDF, but not in Org"
#+end_src

#+results:
| I want to see this in HTML/PDF | but not in Org |

The =results= line is not removed automatically. I have to delete it myself.

Question: wouldn't it be better to check, when option is =silent=, that there is
no =results= line, and remove it if there is one?

Best regards,
  Seb

I tried implementing this change (a simple one-line addition) but it
breaks some other pieces of code block evaluation (inline blocks) which
assume that ":results silent" will not affect the contents of the
buffer.

For not at least I think it would be preferable to leave the meaning of
silent to be "do nothing to the buffer" rather than to remove any
possibly pre-existing results.  Possibly at some point in the future
after I've fixed results removal for inline blocks we should revisit
this decision.

Fine with me. Thanks for trying!
