Hi all,

I'm having trouble modifying the example at
http://orgmode.org/worg/org-tutorials/org-latex-export.html#sec-12-3
to highlight R code blocks. The trouble seems to be that org-mode
identifies R blocks using uppercase R, while pygments looks for
lowercase r.

For example, org exports

\begin{minted}{R}
 2+2
\end{minted}

but pygments doesn't know how to highlight R. If I change to

\begin{minted}{r}
 2+2
\end{minted}

(note the lower case r) then it works, but of course I don't want to
have to perform a find-and-replace every time.

Do you know how to either a) make org-mode identify R blocks with a
lowercase r, or b) make pygments recognize uppercase R, or c) some
other solution I've overlooked?

Thanks!
Ista

Hi Ista,

Put the following expression:

(add-to-list 'org-export-latex-minted-langs '(R "r"))  

in an emacs-lisp code block at the beginning of your org file (or in the
*scratch* buffer) and evaluate it.

Christophe provided the org solution a) and obviously that's the way to go
(maybe one of you could provide a patch to change the default value of
org-export-latex-minted-langs to add the R setting?)

For completeness, and of theoretical interest only, here's how to do b).

o Find the directory where pygments is installed. I just started python
  imported pygments and asked for help:

,----
| $ python
| Python 2.7.1+ (r271:86832, Apr 11 2011, 18:13:53) 
| [GCC 4.5.2] on linux2
| Type "help", "copyright", "credits" or "license" for more information.
| >>> import pygments
| >>> help(pygments)
| Help on package pygments:
| 
| NAME
|     pygments
| 
| FILE
|     /usr/lib/python2.7/dist-packages/pygments/__init__.py
| ...  
`----

o cd /path/to/pygments/lexers, edit the file math.py (you probably have
  to be root) and add the 'R' alias for 'S':

,----
|     ...
|     name = 'S'
|     aliases = ['splus', 's', 'r', 'R']
|     filenames = ['*.S', '*.R']
|     mimetypes = ['text/S-plus', 'text/S', 'text/R']
|     ...
`----

o run (as root) the _mapping.py script to regenerate stuff:

,----
| $ sudo python _mapping.py
`----
