I regularly use org-mode and org-babel to create e.g. exercises or proof-of-principle documents which I export to PDF via the LaTeX exporter. I noticed that the #RESULTS generated by a #+begin_src-#+end_src block are put in a #+begin_example-#+end_example block, which is exported to LaTeX's verbatim environment.

I would like to customize this LaTeX export. I could try and add some #+LATEX_HEADER lines customizing the verbatim environment (e.g. using the fancyvrb package), however, ideally I would like to use the listings environment for the output. Is this possible?

EDIT: I currently use the listings package to format the src blocks, so ideally I would like to use the same formatting for both.

There may be a "smarter" way but if you don't use EXAMPLE blocks for other purpose you could instruct the latex exporter to export them as lstlisting environment, using export filters.

(defun my-latex-export-example-blocks (text backend info)
  "Export example blocks as listings env."
  (when (org-export-derived-backend-p backend 'latex)
      (insert text)
      ;; replace verbatim env by listings
      (goto-char (point-min))
      (replace-string "\\begin{verbatim}" "\\begin{lstlisting}")
      (replace-string "\\end{verbatim}" "\\end{lstlisting}")
      (buffer-substring-no-properties (point-min) (point-max)))))

  • Thanks a lot! For my current use case, this is indeed enough. I simply embed your code example in an emacs-lisp SRC block so that it only applies to this Org file. Note that the environment provided by the listings package is actually called lstlisting. With this example I can even specify options (e.g. \\begin{lstlisting}[frame=single]) specifically for the output/examples. Thanks for the great MWE on export filters. I had tried to write one myself some time ago, but failed.

For reference I found this message on the org-mode mailing list which mentions a way to do this by means of file local #+LATEX_HEADER lines which use the fancyvrb package and redefine the verbatim environment that org-mode #+RESULTS blocks get exported to via:

#+LATEX_HEADER: \RequirePackage{fancyvrb}
#+LATEX_HEADER: \DefineVerbatimEnvironment{verbatim}{Verbatim}{fontsize=\small,formatcom = {\color[rgb]{0.5,0,0}}}
  • Thank you for mentioning this @phaebz. I guess I found the same mailing list post at some point. I have been using it for quite some time now.
