At first I would like to ask whether it is already possible to change
the default settings of the source block header line switches.

The question

> Is it possible to define source block switches globally in org mode?

at https://emacs.stackexchange.com/questions/33971/is-it-possible-to-define-source-block-switches-globally-in-org-mode
demonstrates the usefulness of this feature.

Reading part of the orgmode-manual (http://orgmode.org/manual/Literal-examples.html#Literal-examples), scanning the customization options,
and inspecting the source code gave me the impression that this is not
implemented yet. So, I am filing that as an enhancement request.

1. It should be possible to customize the default settings of the
switches
2. It should be possible to change the default settings of the switches
tree-locally through setting a property. That includes file-local
settings if one sets the property before the first headline.
3. Explicit inner settings should override outer settings, e.g.,
tree-local settings override the customization options and explicit headline
switches override the tree-local settings.
4. For each switch there should also be a negative switch. E.g., if line
numbering is enabled through the customization option it should be
possible to disable it with a tree-local setting or with the source
block headline switches.

Thanks for considering this feature request.

With best regards,
Tobias

Couldn't you use #+property headers?
E.g.

    #+PROPERTY: header-args:R  :session *R*

See:

    http://orgmode.org/org.html#Using-header-arguments

Hope it helps,
Rasmus

No, switches and header arguments are (pityingly) two different concepts.

Currently, switches cannot be modified via header arguments.

But, you are partially right, It could be one solution of this enhancement request to introduce header-arguments for all switches, e.g., :sw-n, :sw+n. The values of those header arguments could be t and nil or, e.g., :sw+n 10.
Then the full mechanism for header arguments would work for switches.

See the description of switches at http://orgmode.org/manual/Literal-examples.html.

Best regards,
Tobias

It is only possible for some of them (i.e., "l" and "i").

This is Emacs. It takes 3 seconds to register a macro (or to write
a regexp) and have "-n" applied on all the blocks.

Of course, a global setting is handier in this case. However, there is
no way to negate a switch, so it would ultimately get in the way.

What you are looking for is a change of the switch syntax. Actually,
merging switch and header arguments would bring automatically 2 3 4,
e.g.,

  #+begin_src emacs-lisp :n t
  ...
  #+end_src

or

  #+begin_src emacs-lisp :n 10
  ...
  #+end_src

or

  #+begin_src emacs-lisp :n nil
  ...
  #+end_src

This is backward incompatible, tho. But, more importantly, it introduces
a slight shift in the source blocks paradigm. Unlike header arguments,
switches do not depend on Babel. E.g.,

  #+begin_src emacs-lisp :exports code
  ...
  #+end_src

and

  #+header: :exports code
  #+begin_src emacs-lisp
  ...
  #+end_src

are equivalent, but not

  #+begin_src emacs-lisp -n
  ...
  #+end_src

and

  #+header: -n
  #+begin_src emacs-lisp
  ...
  #+end_src

We could make a special case for :n :k :l :i :r, i.e., explicitly forbid
them in #+header: lines, or handle them at the parser level.

What do you think? Would you want to work on this?
