Hello,
I'm trying to adapt the example that allows to export a figure both to
tikz and to png so that I don't have to manually add all the header
lines.
Here is what I tried:

#+LATEX_HEADER: \usepackage{tikz}
* Tikz test
Here's a tree, exported to both html and pdf.
#+header: :file (by-backend (latex "tree.tikz") (t "tree.png"))
#+header: :imagemagick yes :iminoptions -density 600 :imoutoptions -geometry 800
#+header: :results file raw
#+header: :fit yes
#+header: :headers '("\\usepackage{tikz}")
#+begin_src latex
\usetikzlibrary{trees}
\begin{tikzpicture}
\node [circle, draw, fill=red!20] at (0,0) {1}
child { node [circle, draw, fill=blue!30] {2}
child { node [circle, draw, fill=green!30] {3} }
child { node [circle, draw, fill=yellow!30] {4} }};
\end{tikzpicture}
#+end_src
The same, with shorter syntax
#+header: :file (by-backend (latex "tree2.tikz") (t "tree2.png"))
#+begin_src tikz
\usetikzlibrary{trees}
\begin{tikzpicture}
\node [circle, draw, fill=red!20] at (0,0) {1}
child { node [circle, draw, fill=blue!30] {2}
child { node [circle, draw, fill=green!30] {3} }
child { node [circle, draw, fill=yellow!30] {4} }};
\end{tikzpicture}
#+end_src
* COMMENT evaluate this first
#+begin_src emacs-lisp :results silent
(defmacro by-backend (&rest body)
`(case org-export-current-backend ,@body))
(org-babel-do-load-languages

(defalias 'org-babel-execute:tikz 'org-babel-execute:latex)

(defvar org-babel-default-header-args:tikz

#+end_src

The first part, where all the headers line are there, works great, but
the second source block for a newly defined language tikz (an alias to
latex with some default headers) does not work unfortunately. In the
exported version, I get a minted source block and not a link.
Am I doing something wrong? Is it possible to have a shorter syntax for
these blocks, or do I have to put all the header lines all the time?
Thanks,
Alan

When I run your tikz src block interactively I get two files created. Not
sure why and I haven't time to edebug step thru the code. But maybe you
can handle that bit.
HTH,

Thank you for the suggestion. At the moment I use a macro (because I
need to put the resulting figure in a figure environment, as I want a
label and caption), but I will give this a try.
Thanks again,
Alan

I'm fairly happy with what I ended up doing (using a macro as I need to
pass some extra arguments, and I don't know how to extend a source block
with custom arguments), so here is my solution.
I define this utility function that is lob-ingested:
#+name: wrap-res
#+BEGIN_SRC emacs-lisp :var link="" :var caption="" :var label="" :results raw :exports none
(concat "#+LABEL: " label "\n#+CAPTION: " caption "\n" link)
#+END_SRC
I also define a macro (it's on one line but for this email I'm wrapping
it)
#+macro: tikzfig #+header: :file (by-backend (latex "$1.tikz") (t
"$1.png")) :imagemagick yes :iminoptions -density 600 :imoutoptions
-geometry 300 :results file raw :fit yes :headers
'("\\usepackage{tikz}") :post
wrap-res(link=*this*,label="fig:$1",caption="$2")
I can then have the following that is exported both in tikz and png (I
do not use svg as I found htlatex lacking for text nodes):
{{{tikzfig(cnf-example,An ordinal in Cantor normal form)}}}
#+begin_src latex
\begin{tikzpicture}[scale=2, every node/.style={transform shape}]
\node[color=blue]{$\omega^{(\omega^\omega\,+\, \omega^2 \times 8 \,+\, \omega)}+ \omega^\omega + \omega^4+ 6$};
\end{tikzpicture}
#+end_src
The first argument of the macro is the label of the figure (with "fig:"
added automatically) as well as the file used to export the figure, the
second argument is the caption.
Hopefully this may be useful to others.
Best,
Alan
