ok, thanks for confirming! I tried a workaround like this:
#+BEGIN_SRC emacs-lisp -r (defun my-tangle-with-r () (interactive) (let* ((temporary-file-directory ".") (tmpname (make-temp-file "switch" nil ".org")) buf data) (write-region (point-min) (point-max) tmpname) (setq buf (find-file-noselect tmpname)) (with-current-buffer buf (setq data (org-element-parse-buffer)) (org-element-map data 'src-block (lambda (src) (org-element-put-property src :switches "-r"))) (erase-buffer) (insert (org-element-interpret-data data)) (save-buffer) (org-babel-tangle)) (kill-buffer buf) (delete-file tmpname))) #+END_SRC Any suggestions for improvement? It seems to work for me, but says it tangled from the temp file instead of the main file (that is expected, but not ideal). I tried some simpler ways but with org-export-with-buffer-copy, for example, I ran into difficulties because of the buffer modification, which I could find a way around that didn't lead to many copies of the buffer being open. In this solution, I just save it and have no issue there.
