Subject: Re: header argument :noweb-ref seems can't be resolved
Date: Mon, 18 Dec 2017 10:08:47 +0800	[thread overview]
Message-ID: <f57a4358-91e9-1bad-316b-b72ccde380ac@gmail.com> (raw)
In-Reply-To: <580C6094-17BE-44C7-8F4C-8BAF3113AA40@ucsd.edu>

The example I original copied from is Emacs org-mode info.
So I rewrite a hand typing content again:
```org
* Test

#+begin_src shell :tangle yes :noweb yes :shebang #!/bin/sh
<<fullest-disk>>
#+end_src

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

*** query all mount disks

#+begin_src shell
df \
#+end_src

*** strip the header row

#+begin_src shell
| sed '1d' \
#+end_src

*** output mount point of fullest disk

#+begin_src shell
| awk '{if (u < +$5) {u = +$5; m = $6}} END {print m}'
#+end_src
```

I can preview the first src block with [C-c C-v v] now. It is correct:
```shell
df \
| sed '1d' \
| awk '{if (u < +$5) {u = +$5; m = $6}} END {print m}'
```
I can tangle it with [C-c C-v t] to same file name shell script 
`babel-noweb-ref.sh`.

But just can't run [C-c C-v e] or [C-c C-]. (Reports same error)
Seems org-mode can find correct noweb-ref for tangle but can't for eval.
