I understand at least the obvious risks in executing source code blocks
inside an unknown org file, but, when I created the org file myself, it
would be nice to be able to export the file without confirming execution
20+ times.
Is there a header element I can set that asks one time for the entire
file (or session, perhaps) for execute permission? I think that would
be safer than blindly turning on permission, for I'd at least get one
opportunity to abort exporting if I was surprised by the existence of
src blocks.
Thanks,
Bill

How about setting `org-confirm-babel-evaluate' to nil
Thanks and Regards

Noorul,
Thank you for the suggestion. Setting that to nil, according to the
documentation, prevents _any_ confirmation requests in any file, at
least as best as I can tell. I don't really want that.
What I want is to have to confirm once at the first code block in an org
file and then have the rest go without confirmation. Since I don't see
the code blocks anyway when I get asked for confirmation, I'm not sure
there's a lot of benefit to a confirmation request on each block, but I
do want a reminder that there is one or more code blocks in a file
before I blithely execute the entire thing.
Bill

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
--8<---------------cut here---------------start------------->8---
(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.

Eric,
That sounds like what I was seeking. Thanks!

I've got 7.01h. I presume you mean something newer than that?

Yes, you'll need to pull a copy of Org-mode from the git repository,
anything pulled after the date of my last message will work.
git clone git://repo.or.cz/org-mode.git
For information on git see http://git-scm.com/
