Good evening,
I am studying Noweb-Ref usage. I set up this example:

(let ((a <<ucase("hEllO, yOU.")>>)

(list a
(type-of a)
b
(type-of b)))
#+end_src

(upcase x)
#+end_src
#+RESULTS: ucase

"WEATHER"
:END:
#+name: emacs-lisp-data

Then I executed each source block.
I was expecting as a result of the first source block to be a list
containing 4 items: double-quoted string, symbol,
double-quoted-string, symbol. Instead what I got was the first string
was not double quoted and the second was. Why doesn't the first value
have double quotes and the third value does have them? The scalar
values return the string and output with double quotes in the last two
source blocks.
Here is how I set up this ECM.
Emacs version: "GNU Emacs 24.4.1 (x86_64-apple-darwin13.4.0, NS
apple-appkit-1265.21)\n of 2015-03-16 on orion"
Org-Mode: "8.3.1" from Git at commit 8c85c990521cc833df9179894f6f8b2934d2231a
Updated autoloads.
I use a ECM startup file to start emacs and org mode for ECMS like this:
=open /Applications/Emacs.app --args --quick --load
~/src/help/.org-mode-ecm.emacs.el= which contains

* [babel] is there a chance to split arguments in src block calls or noweb syntax

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.

Try using a custom babel language. Then using variable assignment from
babel block.
Here I define `fundamental' as a language, which means I can edit src
blocks like `lorem' in a src edit buffer in fundamental mode without
needing to do more than execute the `define-fundamental-as-babel' block or
put that defun in my .emacs. And when I execute the lorem block - as when
it is used in `:var txt=lorem()' - it returns the body as a string.
#+NAME: define-fundamental-as-babel
#+BEGIN_SRC emacs-lisp
(defun org-babel-execute:fundamental (body params)
(format "%s" body))
#+END_SRC
#+NAME: lorem
#+BEGIN_SRC fundamental
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
#+END_SRC
#+NAME: abc
#+BEGIN_SRC emacs-lisp :results value :var txt="A B C"
(concat "txt-->" txt "<--txt")
#+END_SRC
#+CALL: abc( lorem() ) :results raw :wrap EXAMPLE
#+RESULTS:
#+BEGIN_EXAMPLE
txt-->Lorem ipsum dolor sit amet, consectetuer adipiscing elit.<--txt
#+END_EXAMPLE
BTW, there is already `org-babel-execute:latex', which is very handy for
editing LaTeX and then handing it to a src block for further processing.
HTH,
Chuck

Thank you very much for your answer, Chuck!
Your tip to use fundamental mode as an org-executable language was very
useful to me,
thank you very much for your effort to explain the functionality.
At the end, my question was best resolved for me by calling the params
as indexed variable values,
like this:
Instead of calling
#+CALL: namedSrcBlock(arg1="long argument value",arg2="even longer
argument value",...,argN="many args later ")
I created a named table with the argument values
#+NAME: params
|arg1| long argument value|
|arg2| even longer argument value|
...
|argN| many args later|
and called like this:
#+CALL:
namedSrcBlock(arg1=params[0,1],arg2=params[1,1],...,argN=params[N-1,1])
That makes the call line short and the arguments are presented well
readable nearest to the call.
