Hi All,
Passing values across code blocks makes Org babel a powerful meta
programming language:
#+name: input
#+BEGIN_SRC sh :results output
echo "3"
#+END_SRC
#+BEGIN_SRC R :var a=input()
a
#+END_SRC
#+RESULTS:
| 3 |
| |
However, this feature does not work with cache. In case that "input"
code block takes a long time to evaluate, it is a good idea to cache the
result. But that returns "nil" in subsequent function calls:
#+name: input
#+BEGIN_SRC sh :results output :cache yes
echo "3"
#+END_SRC
#+RESULTS[f69ecd305ebd448fc39b05809d214261a777c6bc]: input
: 3
#+BEGIN_SRC R :var a=input()
a
#+END_SRC
#+RESULTS:
: nil
Recalling the cached function should return exactly the same result by
definition of "cache".
Or is there a way to circumvent this by referring to the "RESULT" field
directly?
Cheers,
Benda

I can’t reproduce this on org master.

I believe you can add a name to the results, and use that:
,----
| #+name: input
| #+BEGIN_SRC sh :results output :cache yes
| echo "3"
| #+END_SRC
|
| #+name: input-results
| #+RESULTS[f69ecd305ebd448fc39b05809d214261a777c6bc]: input
| : 3
|
| #+BEGIN_SRC R :var a=input-results
| a
| #+END_SRC
|
| #+RESULTS:
| : 3
`----
Hope this helps,
