Bug: Kill ring contains non-killed output after an export to pdf [8.2.5h (8.2.5h-30-gdd810b-elpa @ /Users/kosta/.emacs.d/elpa/org-20140303/)]

[Konstantin Kliakhandler]

Hello,

Whenever I export an org file to pdf, subsequently my kill-ring contains
the tex code of the intermediate latex stage.

Steps to reproduce:
1. Paste the following into an org buffer:
* test
* another test
2. Press [C-c C-e l p] to export to pdf (note: on my machine the pdf
didn't compile, but this is irrelevant for illustration purposes).
3. Press C-y anywhere in emacs, and you will get the following inserted:

What I would expect to get: the last thing I killed.

The behavior you are seeing is as expected, though I agree that this
behavior is usually not all that useful.  See the variable
org-export-copy-to-kill-ring if you want to turn it off.

Changing the default value of this variable was recently discussed on
this list:

http://thread.gmane.org/gmane.emacs.orgmode/84048/focus=84055

Looks like there haven't been any strong objections to changing it, but
maybe the subject of this thread will grab some more attention for the
issue.

Best,
Richard

Thanks! Now the export is much more usable for me. Out of curiousity,
what is the use case of the default behavior?

I have no idea...if I had to take a guess, it would be that when
exporting a region as a LaTeX *snippet*, such as a table, it could be
useful to yank the resulting code into another buffer.  But I really
can't think of a situation where yanking a whole .tex document from the
kill ring is preferable to just visiting the exported file/buffer.  So
I'm all for changing the default behavior.

Best,
Richard

I think this comes from the time where only the HTML existed, and
where it was only a hack to export small snippets -- in which case
it makes sense to have the copied buffer in the kill-ring, because
you mainly export for the purpose of copying some HTML elsewhere.

Not sure though.

Indeed.  The default in now `nil'.

You forgot to update :version and :package-version keywords in the
defcustom.
