It is not clear to me how to adapt a 3rd party derived mode to
this. Granted, it was never clear to me how to make a mode derived from
CC mode, but that's another thread.
For mode derivation, either I have
(define-derived-mode foo++-mode c++-mode "Foo++"
...)
In which case there will be a parent c++-mode-map and a C++ menu present
when there shouldn't be, or:
(define-derived-mode foo++-mode c-derivative-mode "Foo++"
...)
and fontification is broken.
I've attached an example:
freefem++-mode.el
Description: freefem++ mode
