I can't find any mention of raw strings in C in the GCC manual for version 10.3.0. > > I do not know if that can be fixed by simply adding > > c-before-change-check-raw-strings to C mode's > > c-get-state-before-change-functions. That's the basic idea, yes, with another function to be added to c-before-font-lock-functions. But there are several detailed changes necessary, too. > Alan, are you looking into this? I am now. What's bothering me at the moment is that this is going to make C Mode slower. I suppose I could add an option into C Mode so that raw strings can be enabled only when they're needed, but this would be quite awkward, and a new departure for CC Mode. -- Alan Mackenzie (Nuremberg, Germany)
