Hi Jarmo,
It’s good to hear of your progress!

Why not? It sounds like their code is causing the problem.

You could look at the first answer here for inspiration:
<https://emacs.stackexchange.com/questions/7844/org-mode-have-flycheck-resolve-relative-config-while-editing-code-blocks>.
I’d say you should try to have processing-mode made more robust before
pursuing hacky solutions.

I think your org-babel-execute:processing should return nil (the elisp
value). This should be caught by the first branch of the cond below the
comment “;; insert results based on type” in org-babel-insert-result,
leading to the begin/end not being inserted. (Maybe you already figured
this out, based on your later email.)

This looks bogus. The defvar for org-babel-temporary-directory is not
evaluated when noninteractive is true. I think the defvar should be
unconditional, but I also don’t understand why the code is like that in
the first place, so let’s see if someone knows why before changing it.

Are you not doing (require 'processing-mode)? If you do that, I don’t
understand why the declare-function is also needed.
