Or something like that. Sorry, I don't understand (probably because I missed the beginning of this discussion): what do you mean by "background fontification", and what does it mean for that to have been "completed"? I'm afraid we are not on the same page wrt JIT font-lock related terminology. > Or maybe the fontification could be done immediately after parsing a new > type. Parsing by whom? by CC Mode? If so, CC Mode parsing is itself part of fontification, AFAIU, and is invoked by the JIT font-lock machinery. So I'm confused wrt what you are looking for.
