That was it. Now it is working fine.

This is useless. "noweb-ref" is not a property, and header-args are
always inherited IIRC.

It should be

  :header-args: :noweb-ref fullest-disk

thanks for the quick answer.

However, I have still problems. I have adapted the example,
http://orgmode.org/manual/noweb_002dref.html#noweb_002dref, in the
Orgmode handbook to the changed Babel header properties. However, the
generated file contained only "#!/bin/sh". I have activated property
inheritance for "noweb-ref" and moving the cursor on the #+BEGIN_SRC sh
lines shows that they have ":noweb-ref: fullest-disk" as header
argument.

org-use-property-inheritance is '("noweb-ref")

Here is the changed code from the Org mode manual:

--8<---cut here---start->8---
#+BEGIN_SRC sh :tangle yes :noweb yes :shebang #!/bin/sh
  <>
#+END_SRC

* the mount point of the fullest disk
  :PROPERTIES:
  :header-args: :noweb-ref: fullest-disk
  :END:

** query all mounted disks

#+BEGIN_SRC sh
  df \
#+END_SRC

** strip the header row
#+BEGIN_SRC sh
  |sed '1d' \
#+END_SRC

** sort by the percent full
#+BEGIN_SRC sh
  |awk '{print $5 " " $6}'|sort -n |tail -1 \
#+END_SRC

** extract the mount point
#+BEGIN_SRC sh
  |awk '{print $2}'
#+END_SRC
--8<---cut here---end--->8---

Any ideas why it is still not working.

Regards,
Rainer

[Rainer Hansen]

Hi,

I have tried the following example of using noweb-ref:

--8<---cut here---start->8---
#+BEGIN_SRC sh :tangle yes :noweb yes :shebang #!/bin/sh
<>
#+END_SRC

* the mount point of the fullest disk

** query all mounted disks

#+HEADER: :noweb-ref fullest-disk
#+BEGIN_SRC sh
df \
#+END_SRC


** strip the header row
  :PROPERTIES:
  :noweb-ref: fullest-disk
  :END:

#+BEGIN_SRC sh :noweb yes
|sed '1d' \
#+END_SRC
--8<---cut here---end--->8---


It was mentioned more than 5 years ago as creating problems:
https://lists.gnu.org/archive/html/emacs-orgmode/2011-12/msg00825.html

Now I got the same problem as mentioned in the post of that time - the
created file contains only

--8<---cut here---start->8---
#!/bin/sh
df \
--8<---cut here---end--->8---

Missing is the second block.

Any ideas why?

 Hi Eric,

 As a test case you can still use

 Sorry to ask again:  Would it be possible to speed things up again or to
 make the :noweb-ref feature optional?


 Hi Andreas,

 I've just pushed up a new variable to the git repository.  To enable the
 faster regexp-based method of noweb expansion (which is not able to
 resolve noweb-ref header arguments inherited from sub-tree or file-wide
 properties) put the following in your config.

 (setq *org-babel-use-quick-and-dirty-noweb-expansion* t)

 Best,


Hi Eric,

thanks for this quick-and-dirty fix ;-)  Works great!

Andreas

 Carsten, Bastien, and the community for the great work and for
 sharing.

 Now my question: I am trying to extract code from a .org file by
 tangling with noweb-style references. As I understand from the manual,
 if I write foo in a code block, the line will be expanded with the
 code block named foo. This name I can set with #+NAME:  or with the
 :noweb-ref header argument. Both ways work for me, except that I
 cannont set the :noweb-ref argument through a property.

 The following example is almost verbatim from the manual:

 #+BEGIN_SRC sh :tangle yes :noweb yes :shebang #!/bin/sh
 fullest-disk
 #+END_SRC

 * the mount point of the fullest disk

 ** query all mounted disks

 ** strip the header row

   :noweb-ref: fullest-disk
   :END:
 #+BEGIN_SRC sh :noweb yes
         |sed '1d' \
 #+END_SRC


 If I understand correctly, tangling should produce a file which is a
 concatenation of the two code blocks. However, when I do
 org-babel-tangle, only the first block   is inserted. Am I doing
 something wrong?

 I'm with emacs 23.2.1 and org-mode 7.8.02

 Thanks in advance,

 Hi Tomas,

 You are correct the behavior described above is a bug introduced by a
 fairly recent commit of mine which switched to using regular expressions
 when resolving noweb references in an attempt to decrease the time
 required to tangle code blocks (which can be significant in large code
 blocks).

 However correct performance is more important than fast performance.
 I've just pushed up a patch which fixes the bug you've described, and
 hopefully doesn't slow down the tangling process too significantly.
