Trace Format files on AIX

Trace Format files on AIX

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).

Thanks for your help,

C-h f define-generic-mode
C-h f define-derived-mode

Probably with C-h f generic-mode.

You could also base a mode of a simple one in emacs.
Or maybe this one:-

That's quite easy with Generic mode.

That is not so easy.  Syntax highlighting is done using regexp, this
makes it simple and fast, but not foolproof (except in the case of
something like lisp).  Syntax checking needs to be foolproof, so it
needs parsing.  You could write a simple parser in Emacs.

Or, you could make some regexp that find common mistakes and highlight
them.
See cwarn.el in Emacs for an example of that.

They are.  Syntax highlight could be done by parsing in Emacs, but it
isn't.
It is in some Emacs add-on packages.
