Also there is the issue of knowing when and how much of the resulting buffer to return... Rather than add this as org-babel functionality could I propose that you use a combination of :session execution and a small Emacs helper function like the following untested function? UNTESTED --8<---------------cut here---------------start------------->8--- (defun babel-execute-w-transcript () "Execute the current source-code block, and copy the activated portion of the results buffer to the kill ring." (interactive) (let* ((session-buffer (cdr (assoc :session (third org-babel-get-src-block-info)))) (beginning (save-excursion (set-buffer session-buffer) (process-mark (get-buffer-process (current-buffer))))) ending) (call-interactively org-babel-execute-src-block) (save-excursion (setq ending (process-mark (get-buffer-process (current-buffer)))) (kill-ring-save beginning ending)))) --8<---------------cut here---------------end--------------->8--- if you bind the above to a key w/`local-key-binding' then you can use it to execute all of your source-code blocks and then paste the resulting transcript wherever you like. > > Note that when not using :session, this effect may still be possible on > a language-by-language basis.
