Inline references in noweb?

Inline references in noweb?

Hello,

I’ve read through most of the docs that turn up with the obvious web
searches and I haven’t been able to figure this out. However, it seems
like it should be possible…

I’m quite pleased with how babel and noweb can be used to write
“literate programs” for configuration files and scripts.

Cross references between code blocks with <<noweb-references>> work
just fine. What I’d like, but can’t work out, is how to refer to, for
example, a configuration value inline. Something like this:

  In order to engage the flux capacitor, you must set the
  chronometer dial to ~<<required_date>>~.

  #+begin_src conf :noweb yes
  date: <<required_date>>
  #+end_src

I don’t care how or where “required_date” is defined, I just want the
ability to refer to it in the documentation and in code blocks.

Have I overlooked something obvious?

                                        Be seeing you,
                                          norm

I think this is what you need. I am not sure if you can expand noweb
outside a src block, so I use an inline src block to get this.


#+name: required_date
#+BEGIN_SRC text :exports none
Jan 5, 2020
#+END_SRC

In order to engage the flux capacitor, you must set the
  chronometer dial to src_emacs-lisp[:noweb yes :exports
results]{"<<required_date>>"} {{{results(=Jan 5\, 2020=)}}}.

#+begin_src conf :noweb yes
date: <<required_date>>
#+end_src

Ah, thank you. That was one level of indirection further than I got!
