I don't have the time to implement and document these new header arguments, but the code should not be too difficult if anyone else wants to take a shot at it. In the mean time I'd adjust your hook to wrap the addition of the file local variable in something like ;; -*- emacs-lisp -*- (unless (or (string= (buffer-file-name) "DESCRIPTION") (string= (buffer-file-name) "NAMESPACE")) ;; file local var code goes here ) > > I could use sed or similar to adjust these files, but I would rather > prefer to > a) be able to have org-src-preserve-indentation for tangling as a header > argument > b) a variable in which I can specify in which tangled files should have > the local variables included. > > By the way, the post-tangle-hook approach works, but it has the > disadvantage, that each file needs to be written twice - in the mini > buffer, each tangled file is shown twice.
