Two questions, first the easy one: Does anyone have a 'font-lock-mode' for the trace format files that AIX uses? Assuming the answer to that is no... Where should I start? I would like two basic things when I edit a trace format file. One would be to highlight and color various parts of the file like C mode does in font-lock-mode. But more importantly is a syntax check. I have a package called nxml that does this for xml things. I'm not sure if the two concepts are connected or not (I think not actually).
