Unable to select source code blocks

Unable to select source code blocks

[Giorgio Valoti]

Hi,
I don’t know if I’m missing something but I can’t get the org-babel-goto-named-src-block to work. When I invoke it on the sample file below the autocompletion shows nil and nothing else and if insert the source code block name I get a no match. I’m using org 7.4 with Emacs 23.2.

* Source code navigation test
  #+srcname: test
  #+begin_src sh
    echo 'hello world'
  #+end_src

  #+results: test
  : hello world
* Another item, another source code block
  #+srcname: test2
  #+begin_src sh
    echo 'ciao mondo'
  #+end_src

  #+results: test2
  : ciao mondo
* and so on

Thank you in advance

Giorgio,

this works just fine for me; I don't know what you mean by
autocompletion but I use ido-everywhere and both test and test2 appear
in the prompt for =org-babel-goto-named-src-block=.

Hi Eric,
I don’t use ido-mode (maybe I should? Seems cool!). By autocomplete I meant tab completion.

The problem doesn’t seem related to the autocomplete system, it’s the org-babel-src-block-names function that returns an empty list. I don’t know why, the org-babel-src-name-w-name-regexp used by that function seems ok at a cursory look.

Could you attach a small file with named code blocks which aren't caught
by this function?  I just ran the following in by file of scraps of
code examples and got 60 names returned

#+begin_src emacs-lisp
  (length (org-babel-src-block-names))
#+end_src

Thanks -- Eric

How embarrassing! I used this

  #+begin_src emacs-lisp
 (org-babel-src-block-names)
  #+end_src

which returns nil or so I thought. I was expecting to see the list of source blocks in the results. 

Using your snippet on the same file:

  #+begin_src emacs-lisp
 (length (org-babel-src-block-names))
  #+end_src

  #+results:
  : 19

However, using eval-last-sexp I get a list with nil items. Is it correct?

Hm this should work as well...

That is weird, this should result in the insertion of an Org-mode list
containing the names of the named code blocks in your file.

#+begin_src emacs-lisp :results list
 (org-babel-src-block-names)
#+end_src

If not, then I'm not sure what exactly is being returned by
`org-babel-src-block-names' on your system -- it should be a list of
strings.

You could also try executing the function directly by calling
`eval-expression' M-: (org-babel-src-block-names) within the Org-mode
buffer.

also, make sure you have the latest version of Org-mode.

I get the same results.

I’m using version 7.4 with emacs 23.2. Do you think I should use the development version? I’d have no problem using it but Org has become such an important tool (my thanks to all the contributors, btw!) that I’m reluctant switching to a non-official version.

as I understand it, on your system

  (length (org-babel-src-block-names)) ; => 19

yet

  (org-babel-src-block-names) ; => nil

which seems to be a contradiction.

Yes, it may well be safer to stay at the org-mode release, however I can
only actively confirm behavior on the leading head of the org-mode
development release, as that is what I have installed.

Sorry I can't be of more help, there should be another release in the
not too distant future...
