[O] ob-lua

[Thibault Marin]

Hi list,

I was looking for lua support in source blocks and I came across this
discussion:
https://lists.gnu.org/archive/html/emacs-orgmode/2014-05/msg01149.html.  It
seems that this was never merged, but I am not sure why.

Trying to use the ob-lua.el file linked, it appears to be working for my task (I
just need to be able to pass variables to a lua block).  I only had to make a
small change to the file to get it to work, as `org-babel-get-header' is no
longer available:

132c132
<    (mapcar #'cdr (org-babel-get-header params :var))))
---
>    (remove nil (mapcar (lambda (x) (when (eq (car x) :var) (cdr x))) 
> params))))

There may be a better way to do it, but it seems to work.

So my question is: could this be considered for a merge?  The code does
not seem to support sessions, I am not sure if that should be a blocker.

Thanks,
thibault
