Hi list,
This is my first post, so just let me say first that I have been using
org-mode for 10 months or so and I love it. It's an exceptional
package, and before I ask my question I would just like to thank
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
#+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
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,
Tomas

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.
Cheers,

Hi Eric,
Thanks a lot for your quick reply and fix. Getting the git repo
version scares me a bit, but I guess I'll just have to take the
plunge! Here we go :)
Thanks again,
Tomas

Hi Eric,
unfortunately, for me it does result in a considerably slow down.
(Well, I did not bisect this time but still suspect the commit you
mention in this thread.)
As a test case you can still use
http://pastebin.com/c42jS1Be
from my last post on this matter and expand the first source block.
Sorry to ask again: Would it be possible to speed things up again or to
make the :noweb-ref feature optional?
Regards,
Andreas

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!
