Hi,
I'm trying to evaluate a line of shell code and put its output into a
snippet that will be tangled to a file. My best attempt so far:
#+NAME: hostname
#+BEGIN_SRC sh
hostname -s
#+END_SRC
#+BEGIN_SRC conf :tangle /usr/local/etc/leafnode/config :noweb tangle
expire = 20
server = news.gmane.org
initialfetch = 100
hostname = <<hostname>>.superloopy.io
#+END_SRC
However the result of that tangle includes the shell snippet in
verbatim:
#+RESULTS:
: expire = 20
: server = news.gmane.org
: initialfetch = 100
: hostname = hostname -s.superloopy.io
I suspect this is because it will be executed in the context of "conf"
mode, which does not really have an execution mode. Syntax highlighting
etc works fine, however. I could change to make a shell script to write
the config, but it's not as nice really.
PS: this is an improvement to my existing setup of Leafnode on OS X, if
anybody's interested:

Try `<<hostname()>>'.
See (info "(org) Noweb reference syntax")
... <<code-block-name(optional arguments)>> ...
HTH,

It does indeed! Thank you. I clearly missed that section of the manual.
