Re: tikz for multiple targets

[Eric S Fraga <e.fraga@ucl.ac.uk>]

Hi Eric et al.,

I now have a system I am happy with mostly for using LaTeX code blocks
heading to multiple export targets.  The solution I am using is a
combination of what has been discussed in this thread (by-backend
customisation of headers for babel) and using noweb substitution for the
main content.  I have two LaTeX babel source blocks, one for PDF export
and the other for HTML export.  Each of these has a tikzpicture
environment which then includes the actual instructions for drawing
brought in using noweb.

The problem I have remaining is how to get the version used to export to
PDF via LaTeX to use a figure environment with captioning.  I had
thought that something along these lines would work:

#+begin_src org
  ,#+name: picturecontents
  ,#+begin_src latex :noweb yes :exports none
    \node[red!50!black] (a) {A};
    \node (b) [right of=a] {B};
    \draw[->] (a) -- (b);
  ,#+end_src
  
  ,#+name: flowdiagram
  ,#+header: :exports (if (and (boundp 'backend) (eq (org-export-backend-name backend) (intern "latex"))) "results" "none")
  ,#+header: :results latex
  ,#+header: :noweb yes
  ,#+begin_src latex
    \begin{tikzpicture}
      <<picturecontents>>
    \end{tikzpicture}
  ,#+end_src
  
  ,#+caption: Testing figure caption for figure going to multiple destinations
  ,#+results: flowdiagram
#+end_src

as I expected the export to put the results of the flowdiagram code
block after the results line.  This doesn't work: the exported LaTeX
has no figure environment etc.  The diagram does come out but it is
placed directly into the document.

I hope this all makes sense?  Any suggestions?

thanks,
eric
