expand org variable value in situ

Question

Is there a way to link to an orgmode variable's value? Or at least export it?

I can get a link to jump to the variable definition, but not display its value or export.

for example the text in testmesage below should read: "and I'm like wut ever"

I'm trying to insert live data into a document without turning the whole thing in a src block and using :var.

* huh
#+BEGIN_SRC shell
echo "wut ever"
#+END_SRC
#+NAME: ww
#+RESULTS:
: wut ever

* testmessage
and I'm like [[ww]]
#+END_SRC

Answer 1

Maybe you are looking for inline evaluation of code blocks? Name your code block with #+name: ww and then use and I'm like call_foo(). Like this:

* huh
#+NAME: ww
#+BEGIN_SRC shell
echo "wut ever"
#+END_SRC
#+NAME: ww
#+RESULTS:
: wut ever

* testmessage
and I'm like call_ww()
#+END_SRC

You can execute the inline code block by pressing C-c C-c on it and it will have its result appended after the call in the buffer:

 ... and I'm like call_foo() {{{results(=wut evah=)}}}

That's a verbatim wut evah: you can customize the format a bit using the variable org-babel-inline-result-wrap'. The built-in Org macro results just returns its argument unchanged, but you can also redefine that if you want to do something different: Org mode's middle name is flexibility :-). But note that the doc cautions against that:

Moreover, inline source blocks (see *note Structure of Code Blocks::) use the special ‘results’ macro to mark their output. As such, you are advised against re-defining it, unless you know what you are doing.

In any case, exporting the document (I would tag the huh section as :noexport: so it does not appear in the exported output) produces what you want, I think.
