Re: [O] speeding up Babel Gnuplot

[Thierry Banel]

Here is a patch to avoid generating temporary files multiple times.

There is no way to ensure a single call to
(org-babel-gnuplot-process-vars) without modifying ob-core.el. I don't
want to do that because I would have to change a lot of babel backends.
Thus, I come back to my first light patch.

A 'param' list is passed around. It reflects the #+BEGIN_SRC header. My
patch changes it in-place from:
  (((:var data (3000) (2999) (2998) (2997) ...
to:
  (((:var data . "/tmp/babel-16991kSr/gnuplot-16991YBq") ...

The 'param' list behaves as a cache. There is nothing wrong with that.
The worst thing that can happen is the caching no longer working in case
'param' would be copied some day. Results would stay correct.

Thierry
