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
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
Cheers -- Eric
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.
Cheers,
Rainer
