More specific LaTeX output classes

More specific LaTeX output classes

[Ken Williams]

If I export the following code to LaTeX:

--------------------------
#+begin_src R
CV.t.hat <- rowMeans(loss)[m]
CV.t.hat
#+end_src

#+results:
: [1] 1.135857
--------------------------

, then it looks like this in the *.tex file:

--------------------------
\begin{verbatim}
CV.t.hat <- rowMeans(loss)[m]
CV.t.hat
\end{verbatim}

\begin{verbatim}
 [1] 1.135857
\end{verbatim}
--------------------------

So there's no distinction between input & output, nor between various types of input (e.g. different programming languages).

Would it be possible for the export process to define various classes that default to being exactly like 'verbatim', but could be customized?  After that, a next step might be to provide nice defaults that do things like syntax-highlighting (through the 'minted' package, perhaps), or at least add a visual marker distinguishing between input & output.

Or of course it's possible some of this is already implemented and I've missed it. =)

Yes it is:

#+begin_src emacs-lisp
  (setq org-export-latex-listings 'minted)
  (add-to-list 'org-export-latex-packages-alist '("" "minted")
#+end_src

See also `org-export-latex-listings-langs' for a mapping of Emacs modes
to languages known to pygmentize.

Also see

C-h v org-export-latex-listings RET

for more information (e.g. about the --shell-escape option you'll have
to pass to the LaTeX process).

NB: there's a closing paren missing in the add-to-list line.

Thanks for this (and the pointers that you - and others? - have
provided previously): it finally motivated me to try out minted.

One problem I ran into was that the version of minted.sty that I have
uses "which -s" to find pygmentize, ``which'' complains about -s and the
run fails. I ended up editing minted.sty to get rid of the -s and
everything works smoothly.

The version I have says

\ProvidesPackage{minted}[2010/01/27 v1.6 Yet another Pygments shim for LaTeX]

I checked CTAN and the most recent version is 1.7: that has excised the -s.
