:header-args: over several lines?

:header-args: over several lines?

Hi

I want to add many variables to a subtree. But it seems
that :header-args: only allows one line - is this true? In my case, this
line would be exceedingly long and very difficult to debug.

Is there a way of having :header-args: span several lines (like var+)?

Thanks,

Rainer

Exactly that should work, i.e. using header-args+:

,----
| * foo
|   :PROPERTIES:
|   :header-args+: :exports none
|   :header-args+: :results value
|   :END:
| 
| #+begin_src elisp
|   (org-entry-get nil "header-args")
| #+end_src
| 
| #+RESULTS:
| : :exports none :results value
`----

And it does - should be added to the manual in the example.

Along the same lines:

When I use 

,----
| :header-args: :var RNGKIND="Mersenne-Twister"
| :header-args+: :var RNGNORMALKIND="Inversion"
`----

both variables are transferred - is var+ generally redundant, or i=only
in this case?

Thanks,

Rainer

When I start using :var+ or :header-args+, it mostly does not work for me.
What is the syntax for this? Why and how is this used?

* Test
** Works 1
   :PROPERTIES:
   :header-args: :var x=3
   :header-args+: :var y=4
   :END:

#+begin_src emacs-lisp
 (+ x y)
#+end_src

#+results:
: 7

(but does not work when variables reference other src_blocks, see my
bug report about :header-args:)

** Works 2

#+begin_src emacs-lisp :var u=2 v=3
 (+ u v)
#+end_src

#+results:
: 5

** Works 3

#+header: :var u=2
#+header: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

#+results:
: 5

#+headers: :var u=2
#+headers: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

#+results:
: 5

** Does not work

#+header-args: :var u=2
#+header-args+: :var v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+header-args: :var u=2
#+header-args+: :var+ v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+var: u=2
#+var+: v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u

#+var: u=2 v=3
#+begin_src emacs-lisp
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: u


#+begin_src emacs-lisp :var u=2 :var+ v=3
 (+ u v)
#+end_src

=> progn: Symbol's value as variable is void: v

Can you provide a patch for this?
