Hello, I've got a running page head like this in my document:

\def\CurrentUser{\cldcontext{os.resultof"whoami"}}

\def\Markname { Compiled \date by \CurrentUser \LUATEX +\ConTeXt\ \contextversion }

and later:

\setlayer[cropmark][preset=lefttop,x=3cm,y=-1.5\lineheight]{\Markname}

But when I run this, I get a UCS error that seems to indicate that the *result* of \CurrentUser ("waxhaw\huttar") is getting parsed as a command sequence.

When you want to pass a backslash to Lua you have to use \letterbackslash. Wolfgang
