Hi
when I insert the following source block
#+begin_src sh :exports results :var
ver=(vc-working-revision(buffer-file-name))
echo Revision $ver
#+end_src
into a svn (probably other VCs as well) registered file and execute it
via C-c C-c, it gives me the revision:
#+begin_src sh :exports results :var
ver=(vc-working-revision(buffer-file-name))
echo Revision $ver
#+end_src
#+results:
: Revision 191
So when exporting, I would expect that it also prints "Revision 191",
but I get an error:
vc-file-getprop: Wrong type argument: stringp, nil
Tangling the file with :var ver=(vc-working-revision(buffer-file-name))
as a header argument also works fine.
As the evaluation works, I assume that is a bug somewhere?
Cheers,
Rainer

Hi Rainer,
As part of the export process Org-mode copies the contents of the
Org-mode file to a temporary buffer in which the business of exportation
is performed. This temporary buffer is not associated with any file so
(buffer-file-name) returns nil, which is causing the problem you are
experiencing. I think the best solution would be to replace the call to
(buffer-file-name) with the actual name of the file, e.g.
#+begin_src sh :var file=(vc-working-revision "~/src/babel-dev/scraps.org") :exports results
echo $file Revision
#+end_src
Cheers -- Eric

Hi Eric
thanks a lot for the clarification - that makes perfect sense. I will do
as suggested.

Thanks - it is working now.
But it is a little bit awkward to have the file name (incl. path)
somewhere in the document - can create some problems when renaming the
file or saving it somewhere else).
Is it possible to define it as a kind of variable (property?) in the
headers of the file and reference it in the org file later?

Oh,
I've just remembered that during export Org-mode saves this file-name
information in the temporary variable `org-current-export-file'.
So the following will work, even though it relies upon undocumented
internals of Org-mode which could change at some point.
#+begin_src sh :var file=(vc-working-revision (or (buffer-file-name) org-current-export-file)) :exports results
echo $file Revision
#+end_src

And this works very well with an inline src snippet (tested with git
and RCS). Very nice!

Thanks a lot Eric F. - that inline syntax was also something I was
looking for - I'll put it into my document on Monday morning.
