Hi, Apologies -- the error stemmed from some of my own code in emacspeak
which was refering to that variable which appears to have now
disappeared. I need to study the code in the updated eldoc to have
emacspeak work cleanly with the newer eldoc:-) Apologies for the nois.
Let me know if I can help. That variable was an internal implementation detail, so it went away and was replaced by something better. I can maybe help you understand how to use ElDoc's public API to achieve your goals.
Just guessing but maybe what you want is a "speaking" member of eldoc-display-functions. Have a read of its docstring.
