Hi I am using R for package writing in R, and the org file is under svn version control.
I would like to keep the version of the R package, as stated in the DESCRIPTION file, in sync with the svn revision, so I thought about using variables for that. But my approach below obviosly does not work, as in the tangled DESCRIPTION file, it says Version: 0.$VER Is it possible to have, during tangling, the actual value in the source file instead of the variable? Thanks, Rainer * The DESCRIPTION File #+begin_src sh :tangle ./asm/DESCRIPTION :shebang :padline no :var VER=(vc-working-revision (buffer-file-name)) Package: asm Type: Package Title: Alien spread management simulation model Version: 0.$VER Date: 2011-06-08 Author: Rainer M.
