Re: [O] org-babel source block unevaluated into variable?

[Johan W . Klüwer]

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.

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.

Johan:

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

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.

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.
