Yes, exactly :) I'm not surprised it doesn't work, but I don't see why
it cannot work.

This supposes that the command does not depend on the TeXmacs state. I
was hoping to get information about the TeXmacs state in this
way. Something like:


DATA_BEGIN command:(plugin-eval "foo" "default" (string-append "callback:
pos foo " (object->string (position-get foo)))) DATA_END


I'll have to cook up another system.
