Re: [Orgmode] File-level execute permissions?

Hi Bill,

The `org-confirm-babel-evaluate' variable can be set to a function which
can query the user to confirm code block evaluation.  The following code
does two things.
1) it creates and maintains a list of the files that the user has said
   are safe for evaluation (this list will need to be rebuilt every time
   you re-start Emacs)
2) it shows the language and body of the code block to the user when
   querying for evaluation

(setq babel-safe-files '())

(defun my-babel-confirmation (lang body)
  (let ((file (buffer-file-name)))
    (if (member file babel-safe-files)
        nil
      (if (y-or-n-p
           (format
            (concat "#+begin_src %s\n%s#+end_src\n"
                    "Evaluate this code block "
                    "(and all others in this file) "
                    "on your system? ") lang body))
          (prog1 nil
            (setq babel-safe-files (cons file babel-safe-files)))
        t))))

(setq org-confirm-babel-evaluate #'my-babel-confirmation)
--8<---------------cut here---------------end--------------->8---

This above can be added to your configuration to get close to the
functionality you describe.

I agree that the default confirmation should show the code block in
question when asking if it should be evaluated.  I'll add this to our
development task list.

Note: the above requires that you pull down the latest version of
Org-mode.

Best -- Eric
