[NTG-context] Any syntax highlighter for C++ MKIV?

The verbatim function in MKIV is really powerful, and pretty printing of progamming language is easy. But unfortuantely, I do not know how to modify the php, or lua pretty printing formatter to what I want --- C++ formatter. After laboriously searching, I failed to find any working formatter. Is this really really easy, nobody wants to post it? Or there is no person in need of such a formatter, but only me? I tried vim highlighting module in the wiki, but it always complains cannot find "xxx-vimsyntax.tmp" and something, in both windows and unbuntu. I know it is something about mtxrun curruent version. But I still cannot fix it after I did following the posts in this mailing list.
