 Just call org-babel-tangle with a prefix argument and it only tangles
 the current block

Hi all,

I just pulled a fresh version of org, and this tangling an individual
block only works if there's a :tangle header argument present.  I
don't think this is the intended behavior!  The problem, it seems, is
that when :tangle is not present, the (or ...) in the code below
always evaluates to true.

#+begin_src emacs-lisp
  (unless (or (cdr (assoc :tangle (nth 2 (org-babel-get-src-block-info
  target-file)
(setq target-file
  (read-from-minibuffer Tangle to:  (buffer-file-name)
#+end_src

Thanks for raising this issue.  I can not apply patches to the git
repository until the recent git issues are sorted, so I am attaching the
patch to this email so that you can apply it locally if you like.  I
will push this up once our git repository is back in working order.

Best,

 Hi,

 I did not know this either.  Thanks for the hint!

 Shouldn't this be mentioned in the manual (14.4)?

 I have two questions/issues about this:
 (1) Can I get noweb-references to be expanded by this?  Or how would I
 tangle one block with noweb references expanded?

 There was a conflict between the narrowing to a single code block caused
 by the prefix argument, and the code which searches for replacements to
 noweb elements.  I've just pushed up a fix so noweb elements should now
 expand as normal.

 
 (2) I am asked for a filename.  But the header argument :tangle somefile
 is overruling my input, which is un-expected.


 This is now fixed as well.


Hi Eric,

thanks for both fixes!  Tangling of single source blocks is a really
nice feature now!

Regards,
Andreas

2012-03-04 Thread Sylvain Rousseau
Under Gnome, I'm using this at the beginning of a sh source block:

 echo -e #! /bin/bash\n/usr/bin/gksudo -p -m Password  /tmp/gksudo-stdout
 chmod +x /tmp/gksudo-stdout
 SUDO_ASKPASS=/tmp/gksudo-stdout sudo -A -s

You could set up sudo so that it does not require a password and prefix each
command that needs to be run as root with sudo:

--8---cut here---start-8---

* foo

#+BEGIN_SRC sh
sudo id

#+END_SRC

#+RESULTS:
: uid=0(root) gid=0(root) groups=0(root)
--8---cut here---end---8---

Not sure how sudo would interact with babel if you had to type in a password.
