Cool. That was what I tried to archive. > Let me know if this leaves anything out. For now, no. Some of the examples from the Eigen tutorial render horribly, but it's mostly 'cause they have several matrices/vectors in one 'program' and strings are added to the beginning, e.g. "m * v=\n..." where '...' is a matrix. But I can't think of an easy remedy to this. Thanks, Rasmus -- Together we'll stand, divided we'll fall

I actually applied this patch, undid the portion in ob-C.el because we
shouldn't be modifying org-babel-load-languages from ob-* files, and
added another change which include the org-src-lang-mode languages to
the options in org-babel-demarcate-block.
Let me know if this leaves anything out.

Scratch it, it's not working as it should.

There are known knowns; there are things we know that we know.

Thanks for the pointers!
Do you find the attached patch acceptable?

Subject: [PATCH] Better C++ recognition
* ob-C.el: Added =C++= to =`org-babel-load-languages'=
automatically after loading =C=.
* org-src.el (org-src-lang-modes): Added association between
language =C++= and =`c++-mode'=.
=C++= is added to org-babel-load-languages to make
`org-babel-demarcate-block' recognize =C++= as a proper language.

Re: [O] [ob][bug] C++-mode is unknown
Use the `org-src-lang-modes' variable to associate a src code block name
with a major mode. This list already contains ("cpp" . c++) for C++
code blocks, but perhaps ("C++" . c++) should be added as well.
Best,

Oh, and here's my details if relevant: Org-mode version 8.0.3 (release_8.0.3-309-gabacff @ /usr/share/emacs/site-lisp/org/) GNU Emacs 24.3.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 3.8.2) of 2013-07-05 on *host*. –Rasmus -- Enough with the bla bla!
[O] [ob][bug] C++-mode is unknown
Hi, The Emacs C++ mode is called c++-mode. In babel C++ is C++. Hence, the following problematic case holds. With the block, (lowercase c) #+begin_src c++ ... #+end_src I can edit it in the c++-mode and get nice fontification, but I can't execute it. With (capital c) #+begin_src C++ ... #+end_src I can execute the block in Org, but I can't edit it in c++-mode. I'm not very knowledgeable about Babel, so the best fix I could find was adding (defalias 'C++-mode 'c++-mode) to the top of ob-c.el (after requiring cc-mode). Of course C++ could also be renamed c++, but the correct name does in fact seem to use capitals (cf. Wikipedia). Ob-template didn't mention how to associate a language with a given mode.
