Hi all,
for quite some time I've had the following in my .emacs:
--8<---------------cut here---------------start------------->8---
;; This Snippet returns the name of the current source block.
;; An elisp block to simplify the =:prologue= definition.
;; Author: Eric Schulte
;; It is useful to insert the debug message 'Entering foo()' as output.
;; For R code blocks, enable it with this line:
;; #+PROPERTY: header-args:R :session *R* :prologue (format "print(\"entering %s\")" (get-current-name))
(defun get-current-name ()
(or (when org-babel-current-src-block-location
(save-excursion
(goto-char org-babel-current-src-block-location)
(while (and (forward-line -1)
(looking-at org-babel-multi-line-header-regexp)))
(when (looking-at org-babel-src-name-w-name-regexp)
(org-no-properties (match-string 3)))))
""))
--8<---------------cut here---------------end--------------->8---
That had stopped working during export (my main use-case) a few weeks
back. Now, org-babel-src-name-w-name-regexp is gone from the source
so that this snippet is completely broken.
I would like to again have the name of the source block displayed
during execution of src blocks. Is there a function in org already?
And if not, how would the proposed function look like so that it works
during export as well?
Thanks in advance!
Andreas

Seems to come from:
* 49a656a ob-core: Remove `org-babel-src-name-w-name-regexp' <Nicolas Goaziou> (2015-05-01)
* cec47a6 ob-core: Change `org-babel-named-src-block-regexp-for-name' signature <Nicolas Goaziou> (2015-05-01)
Maybe looking at the diff would give you the way to translate the regexp
into some newer form?
Best regards,
Seb

Yes, I was lazy and following the change to
`org-babel-named-src-block-regexp-for-name' is easy enough.
But how does that solve my first problem?
During export (and preview (C-c C-v v)) the code block name is not
displayed.
Here is an expample:
--8<---------------cut here---------------start------------->8---
#+PROPERTY: header-args:R :session *testR* :prologue (format "print(\"entering %s\")" (get-current-name))
* Setup :noexport:
#+begin_src emacs-lisp :results none
(defun get-current-name ()
(or (when org-babel-current-src-block-location
(save-excursion
(goto-char org-babel-current-src-block-location)
(while (and (forward-line -1)
(looking-at org-babel-multi-line-header-regexp)))
(when (looking-at (org-babel-named-src-block-regexp-for-name))
(org-match-string-no-properties 9))))
""))
(message (get-current-name))
#+end_src
* Test echo name during export
Execute this source block (C-c C-c) and look into *testR*. There
should be a message "entering testname".
Export this file and look into *testR*. The message is "entering ".
#+name: testname
#+begin_src R
1:10
#+end_src
--8<---------------cut here---------------end--------------->8---
Thanks,
Andreas

See `org-babel-exp-code-template'.

Thanks for looking into this.
If I get you correctly, you are suggesting a way to have the name
of the code block shown in the exported file. What I am after is
to have the name of the code block shown *in the R session*
during evaluation at export (to easily see where things fail).
Sorry for being unclear.
If your hint helps there as well, could you elaborate a bit?
Thanks,
Andreas
