Hi, it is maybe not as easy to do as I thought it would be. It is similar to adding some kind of character control (for adding color, etc.) into the output but as the mrxvt structure use a lot the same character pointer which it will increment when it has processed it, it looks impossible to add new character in this buffer...
If ever you can do something like this, it may begin in rxvt_process_getc (command.c) which loops through the buffer until some limit is reached or control character is reached, so that when rxvt_scr_add_lines (screen.c) is called, it will use the same PVTS(r, page)->rstyle. Maybe you can do something like an artificial change of "rstyle" when you see your regexp and break the loop in rxvt_process_getc before? Or else, you may do something at display time rather than processing time. For this, you must directly change PSCR(r, page).rend when you see your regexp in PSCR(r, page).text. But what I find more complicated here is that both arrays are indexed by lines! So you must consider your regexp being maybe on several lines (whereas working directly in the output buffer, everything is on a single line; and what if the text is not fully processed from the output buffer into the display arrays?). Such a change should probably begin in rxvt_scr_refresh which is the first step before display...
