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.

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

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 Sylvain.

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.
