Hi,
I'm exploring some ways to include a complex LaTeX preamble using source
blocks. Consider this (code at the end of this message), that works fine.
My question is: In order to do it all in a single block, would there be
any way to pass the output of the first block as an argument to a
function, and put that function as a header arg (results)...?
Best Regards,
Juan Manuel

I think you might do better to use noweb chunks, viz.
#+name: pre-amble
#+begin_src latex :exports none
\usepackage{luacode}
\usepackage{fontspec}
\directlua
{
[...]
}
}
\setmainfont{Linux Libertine O}
[RawFeature={+ktest}]
#+end_src
#+begin_src latex :noweb yes :results drawer
,#+LaTeX_HEADER: <<pre-amble>>
#+end_src
Evaluating the latter chunk (assuming `org-babel-load-languages' has (latex . t)) gives what I suspect you want.
Note that using a drawer allows replacement of the result.
HTH,
Chuck

wow, it works great! Many thanks. I did not know this use of noweb ...
