disable tangling for an entire section?

disable tangling for an entire section?

[Bill White]

Is there a simple way to disable tangling for an entire section's code
blocks?  Or to put it a different way, can tangling be toggled at the
section level and not just the code-block level?

I tried this:

** a section in my file
:PROPERTIES:
:tangle: no
:END:

by analogy from 
   #+PROPERTY: tangle yes
in (info "(org) Header arguments in Org mode properties"), but code
blocks in that section were still tangled.

Org-mode version 8.0.2 (release_8.0.2-61-g22dfa7 @ /home/billw/Dropbox/org/org-mode/lisp/)
GNU Emacs 24.3.1 (i686-pc-linux-gnu, GTK+ Version 3.6.0) of 2013-03-11 on wri

Thanks -

Hi,

That should work, I think, and it does work for me (on 8.0.1).
I cannot reproduce the problem.

Yours,
Christian

That must work, yes. Except if you have ":tangle" header arguments set on
sub-subtrees, or on code blocks, of course.

Best regards,

Thank you Christian and Sebastien for your replies.

I was hoping that a higher-level setting would override all tangle
settings under it, no matter what they might be.  This would make it
possible to change an entire section's tangling without fussing with
each code block's setting.

For example, I had hoped that the following would disable tangling for
both code blocks, but for me[1] even under 'emacs -Q' the first block is
tangled:

* headline
:PROPERTIES:
:tangle:   no
:END:

#+begin_src perl :tangle yes
2 + 2
#+end_src

#+begin_src perl :tangle no
3 + 3
#+end_src

The status quo makes more sense, I think. It allows you to easily change
an entire section's tangling but make specific exceptions that
override the general setting.

I agree with Christian here. But you could trick org into achieving what
you want, in specifying a tangle target in the PROPERTIES sectio, given
that you only use :tangle yes :

* headline
:PROPERTIES:
:tangle:   tmp.tmp
:END:

#+begin_src perl :tangle yes
2 + 2
#+end_src
#+begin_src perl :tangle no
3 + 3
#+end_src
 

In this case, the the first code block can be tangled into tmp.tmp and
the second one won't. So no harm done to your "clean" tangled file, only
the tmp.tmp, which you can discard afterwords.

Cheers,

Rainer

I wish I'd thought of that!  Many thanks -
