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.
Here's the error:
! Undefined control sequence.
1 >> % see ConTeXt wiki http://wiki.contextgarden.net/Imposition#Cut_marks

3 %% TODO: make sure this doesn't reevaluate every time
4 %% the command sequence is used!
5 \define\CurrentUser{\cldcontext{os.resultof"whoami"}}

7 \def\Markname { Compiled \date by \CurrentUser \LUATEX
+\ConTeXt\ \conte
xtversion. SVN }
...

\cldcontext #1x-\directlua {context(#1)}
\Markname #- Compiled \date by \CurrentUser
\LUATEX +\ConTeXt \
\contextvers...
l.24 ...t=lefttop,x=3cm,y=-1.5\lineheight]{\Markname
}
How can I change the definition of \CurrentUser, or \Markname, to output
the result of \CurrentUser as-is, instead of parsing the result?
I tried (somewhat blindly) changing \def to \define, but it didn't make
any difference.
At the same time, I want to make sure that the processor won't be making
an OS system call to "whoami" every time \CurrentUser is evaluated: I
want it to happen only once, when \CurrentUser is defined.
Here is my complete working example:
\def\CurrentUser{\cldcontext{os.resultof"whoami"}}
\def\Markname { Compiled \date by \CurrentUser \LUATEX +\ConTeXt\
\contextversion. }
\setuplayout[location=middle,marking=on]
\definelayer[cropmark][state=repeat,width=\paperwidth,height=\paperheight]
\setupbackgrounds[page][background=cropmark]
\setlayer[cropmark][preset=lefttop,x=3cm,y=-1.5\lineheight]{\Markname}
\starttext
Foo
\stoptext
Thanks for any help.
Lars
