Hi all,

Splitting header arguments for source blocks into different lines works 
very fine,
(and leads one to put more and more args in the header... )

Is there a chance or trick to do similarly when calling such src blocks?
Somehow like in shell scripts a backslash at the end of a line will 
signal continuation?
(example see below)

Any suggestions or workarounds or best-practices to make the call lines 
better readable and editable are welcome!

Kind regards,

Olaf




What I mean:

#+NAME: namedSrcBlock
#+HEADER: :var arg1="val for arg1"
#+HEADER: :var arg2="val for arg2"
...
#+HEADER: :var argN="val for argN"
#+BEGIN_SRC
...
#+END_SRC

results in long call lines for #CALL: or noweb syntax hard to edit

#+CALL: namedSrcBlock(arg1="long argument value",arg2="even longer 
argument value",...,argN="many args later ")
<<namedSrcBlock(arg1="....",....,argN="...")>>


How to split those long lines, so that each arg-value pair stands on its 
own line?


The 'orgish' way would be sth like this, I guess:

#+CALL namedSrcBlock
#+ARGS: :arg arg1="..:"
#+ARGS: :arg arg2="..."
#+CALL_END

in noweb ref might be
<<namedSrcBlock(arg1="long argument value",\\SPACE
                    arg2="even longer argument value",\\SPACE
                    ... \\SPACE
                    argN="many args later")>>

But I did not find such anywhere.
