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 > > Rainer > >> >> Cheers, >> >> Rainer >> >> >>> Cheers -- Eric >> >>> Rainer M Krug <r.m.k...@gmail.com> writes: >> >>>> 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 >> >> _______________________________________________ Emacs-orgmode mailing list Please use `Reply All' to send replies to the list.
