Good point. The REPL should be created in the same subprocess; the
REPL display and interaction must happen in the user main emacs.  If
the REPL is based on comint, it should be relatively easy to
implement.

With this solution, the user and the REPL/execution will be in
separate processes; so there will be disavantages.  For basic
interactions, mostly based on text input/output, it should work well.

Good point.  I'll switch to such a solution as soon as possible.

My bad: I should have compiled the demo code in a standalone emacs.
I forgot to require some libraries: cl-lib and org-id.

I've now tested with your command line (thanks).  It should now
work. Sorry about that.

Thanks!


Please find attached the new set of patchs.  I'll switch to using a
clone and a branch soon, in case if you prefer to wait.

Thanks again!
