I don't see a direct answer to the original question in the thread, so here is an example of how I do it taken from https://raw.githubusercontent.com/SciCrunch/sparc-curation/master/docs/developer-guide.org. You can ctrl-f for racket-graph-helper to see the relevant blocks. A reduced version is below. Recall that I use https://github.com/wallyqs/ob-racket. I use this pattern all over the place in my org blocks. Best, Tom
* Use the code :cache yes" #+begin_src racket :lang racket/base :noweb yes <<racket-helper>> (helper-function "this should work") #+end_src #+RESULTS: : this should work hello world * Define the helpers #+name: racket-helper #+header: :prologue "#lang racket/base" #+begin_src racket :lang racket/base (define (helper-function arg) (string-append arg " hello world")) #+end_src
