Babel Tangling Only Blocks Under One Heading in a File with Multiple Blocks.

Babel Tangling Only Blocks Under One Heading in a File with Multiple Blocks.

[Ian Barton]

I am using org to keep configuration files for my various servers. A 
typical file might look like:

* Postfix
** main.cf
#+BEGIN_SRC sh :tangle 
~/dropbox/configuration_files/wilkesley.org/postfix/main.cf :exports 
none :noweb yes

#+END_SRC
** master.cf

* Dovecot
** dovecot.conf

Mostly I only change one configuration file and don't need to tangle 
every block in my org file. Is there any method to only tangle files 
under a particular heading? Thus I could regenerate just my Postfix 
config files and not my Dovecot ones.

Ian.

Check org-narrow-to-subtree - you can narrow to subtree and then tangle.

Cheers,

Thanks, that does the job nicely.
