org-babel source block unevaluated into variable?

org-babel source block unevaluated into variable?

[Johan W. Klüwer]

[-- Attachment #1: Type: text/plain, Size: 583 bytes --]

Is there a way to assign the uninterpreted content of an executable source
block to a variable? Preferably, using a :var header argument? That is,
return the text in the block, not the result of evaluating it, and
preferably with noweb references expanded.

"example" blocks return text the way I want, but they can't be evaluated,
and of course noweb is ruled out for them.

The function org-babel-ref-resolve could to the job if there were a switch
to block evaluation.


Why this is interesting: I wish to use url-hexify-string on the text of a
named SPARQL query.

Cheers, Johan

Johan:

You can try the following:

#+NAME: lscode
#+BEGIN_ASCII
ls -alh
#+END_ASCII

#+BEGIN_SRC emacs-lisp :var code=lscode
(message code)
#+END_SRC

#+RESULTS:
: ls -alh

I haven't tried the noweb references, but it does return the code block in
the variable.

To use expanded noweb references you can use text source blocks

#+NAME: lscode
#+BEGIN_SRC *text*
ls -alh
#+END_SRC


#+NAME: example
#+BEGIN_SRC sh :noweb yes
echo <<lscode>>
#+END_SRC

#+RESULTS: example
: ls -alh


#+BEGIN_SRC emacs-lisp :var code=example
(message code)
#+END_SRC

#+RESULTS:
: ls -alh

Thanks Martin,

These are good suggestions, but it's not quite what I am after. In your
second example, I would like ":var code=example" to make "code" carry the
full (and expanded) text of the "example" block, i.e. to have

  echo ls -alh

as the result -- the code itself, unevaluated.

Following up: A function like this one should help.

(defun expand-named-babel-block (block)
    (save-excursion
    (org-babel-goto-named-src-block block)
    (org-babel-expand-src-block)))

However ... there's something strange here with
org-babel-goto-named-src-block (org 9.0.9). It just jumps to the first
source block in the file, which is not that useful :) I'll try to update
org and see.

Johan:

Maybe this one would work for you:

#+NAME: first
#+BEGIN_SRC js
function one() {
    return 1;
}
#+END_SRC


#+NAME: second
#+BEGIN_SRC js
function two() {
    return 2;
}
#+END_SRC


#+NAME: third
#+BEGIN_SRC js
function three() {
    return 3;
}
#+END_SRC


#+NAME: all
#+BEGIN_SRC sh :results output :noweb yes
echo "
<<second>>

<<first>>

function test(){ console.log('test');}

<<third>>"
#+END_SRC



#+BEGIN_SRC python :results output :var code=all
print code
#+END_SRC

#+RESULTS:
#+begin_example

function two() {
    return 2
}

function one() {
    return 1;
}

function test(){ console.log('test');}

function three() {
    return 3;
}

#+end_example
