I am trying to put together a derived backend that makes use of Src Block
:parameters attribute.
I can see that the header in a begin_src block is picked up by
org-element-src-block-parser, as it should be when I try it interactively
But not when I try
M-: (org-export-to-buffer 'my-latex "*latex out*") RET
Here is an example:
=========================
#+BEGIN_SRC emacs-lisp
(org-export-define-derived-backend my-latex e-latex
:translate-alist ((src-block . org-rnw-src-block)))
(defun org-rnw-src-block (src-block contents info)
(org-element-src-block-interpreter src-block contents))
#+END_SRC
(progn
(forward-line 3)
(org-element-src-block-interpreter (org-element-src-block-parser) nil))
move cursor back after last paren and type C-x C-e
#+name: bblock
#+BEGIN_SRC R :exports code :et-cetera
rnorm(2)+1
#+END_SRC
===========================
Typing C-x C-e as above yields
"#+BEGIN_SRC R :exports code :et-cetera
rnorm(2)+1
#+END_SRC"
but using the org-export-to-buffer line above yields
[much deleted]
#+BEGIN_SRC R
rnorm(2)+1
#+END_SRC
% Generated by Org mode 7.8.10 in Emacs 23.3.50.1.
\end{document}
I'd really like to have access to the header elements.
AFAICS :parameters is nowhere to be found when using org-export-to-buffer.
What can I do??

This is because src blocks are executed before buffer is parsed. You can
try to call `org-export-blocks-preprocess' on the following buffer
(associated to a file):
--8<---------------cut here---------------start------------->8---
#+name: bblock
#+BEGIN_SRC R :exports code :et-cetera
rnorm(2)+1
#+END_SRC
--8<---------------cut here---------------end--------------->8---
and see what is really parsed: the removal happens on the Babel side.
Depending on your needs, you may want to use ATTR_LATEX keyword instead.

Thanks! I get it.
It turns out I can piggyback extra info needed on the ':name' element
and use that in lieu of ':parameters'.
BTW, "#+name: aname" and "#+NAME: aname" are handled differently in e-latex. The
former gets placed in the latex output as "\#+name: aname". Bug?

There is a known bug about affiliated keywords not being removed during
export, but I don't know if you're describing the same problem.
Do you have an ECM illustrating it ?

Yes and No.
I tried to put an ECM together earlier today, but couldn't trigger the
bug.
Then a few minutes ago it bit.
And this simple subtree triggered it:
,----
| * here is a subtree to export
| #+COMMENT: (org-export-to-buffer 'e-latex "*rnw out*" t)
|
| ** src block
|
| #+name: ablock
| #+begin_src R
| rnorm(10)
| #+end_src
`----
But I restarted emacs, loaded contrib/lisp/org-export.el and
contrib/lisp/org-e-latex.el, and ran the command in the COMMENT line
again and the *rnw out* buffer looked justed fine (no \#+name... stuff).
And I repeated as many of my earlier steps as I could and still no bug bite.
So whatever the problem is, it is not something I can reliably reproduce.
If I come up with anything, I'll get back to you.
