org links inside source code blocks

Question

In my org file I have something like:

#+NAME: fig:figure
\begin{figure}
   \includegraphics{figure}
\end{figure}

and then I want to reference that figure inside a code block:

#+BEGIN_SRC r
    # code ...
    x <- 3
    # more code for fig. [[fig:figure]]
    plot(1:x)
#+END_SRC

[[fig:figure]] is not a link in the org document and does not get resolved when exported, it simply stays verbatim in the text. Is it somehow possible to make it reference the figure?

Answer 1

I think you can do it like this. They key is the mathescape option for minted, and using minted for src block fontification.

#+BEGIN_SRC emacs-lisp
(setq org-latex-minted-options
     '(("frame" "lines") ("linenos=true") ("mathescape")))
#+END_SRC



#+caption: figure for testing \label{fig-1}
[[./test.png]]

#+BEGIN_SRC ipython
5
# see figure $\ref{fig-1}$
4
#+END_SRC
