I think I could do that.
Not each of these. AFAIU, :cmd header property in ob-screen defines which shell to use. Knowing shell name, you can deduce the function name to be used for variable assignments. See how it is done in `org-babel-expand-src-block'. > But if I also see org-babel-shell-initialize in ob-shell that looks like it > creates defaliases for each of these to (org-babel-execute:shell) and > #'org-babel-variable-assignments:shell. The convention is for every possible #+begin_src lang to have org-babel-variable-assignments:LANG. ob-shell just tries to avoid unnecessary code duplication and instead of writing identical org-babel-variable-assignments:sh org-babel-variable-assignments:bash, org-babel-variables-assignents:zsh, ..., it generates them using a macro. > I'm not sure how that is very different from what I've done.

AFAIU, you don't need to juggle with macros as ob-shell does. Something similar to `org-babel-expand-src-block' will do. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
