Hi

when tangling the following with Org-mode version 7.5
(release_7.5.358.g5194), test.R begins with an empty line - but when
tangling with 7.5, it does not start with an empty line.

The empty line occurs *after* the shebang. Empty lines are usually not a
problem, but I am using
http://orgmode.org/worg/org-contrib/babel/examples/Rpackage.html for a
package, and this empty line makes my DESCRIPTION file invalid.
For the moment I am reverting to 7.5, but it would be great if this could be
fixed.

* test
#+begin_src R :tangle test.R :shebang
This is
a test
#+end_src

Cheers,

Rainer

Hi Rainer,

I actually believe that the current behavior is the more "correct"
behavior, however I'm not sure if the default padding behavior is
technically specified when no ":padline" header argument is given.

The following combination of header arguments results in the desired
behavior.  Note that the shebang line isn't required, I was just using
it to easily view file contents and to see if an empty line was inserted
between shebang and contents.

#+begin_src R :tangle test.R :shebang #!/bin/cat :padline no
This is
a test
#+end_src

Thanks - that is working. But :padline does not seem to be in the manual?

Thanks for your help,

Rainer

Hi Rainer,

There is a section on the :padline header argument in the "Specific
Header Arguments" section of the Org-mode documentation, however you
most likely need a more recent version of the documentation loaded.

This header and documentation were added in March.
