Wolfgang (and list),

The above code works fine with simple texts, but is not movable. Adding 
a footnote, as in the following, to the text section shows that:


   \starttext
   \startTranslation[language=en]
  It betrays a slow-witted mentality to pursue the streams, but not to
  see the sources of things.%
  \footnote{%
\startTranslation[language=la]
  Tardi ingeni est rivulos consectari, fontes rerum non videre.
\stopTranslation%
  }
   \stopTranslation
   \stoptext


or even by:

   \starttext
  It betrays a slow-witted mentality to pursue the streams, but not to
  see the sources of things.%
  \footnote{%
\startTranslation[language=la]
  Tardi ingeni est rivulos consectari, fontes rerum non videre.
\stopTranslation%
  }
   \stoptext


In LaTeX, this might be dealt with by a combination robust command 
definitions and \protected. When I wrote an endnotes routine in LaTeX, I 
used those and wrote the notes to a file which was then read back in at 
the appropriate time, but that does not help with pagenotes.


I imagine that at the time the footnote is processed the 
Translationsetups and Translationlanguage macros are no longer defined, 
and I have no idea how one would reference the buffer contents, although 
it does look like they have stable names in the log file.


Can this be made movable?

Also, am I correct that the \iffirstargument test in the definition of 
dostarttranslation is redundant? My understanding is that \dosingleempty 
assures the presence of [#1].

Hi Wolfgang,
Thank you for your help. I actually forgot this :
\ definetypeface [mainface] [ss] [sans] [dejavu] [default] [rscale = auto].
The problem is that I'm still new with ConTeXt, but I think I can say

No real problem. My installed version is working very well so far, as I
rescale the graphics afterwards.

Thanks again...
This gets rid of the error, but it seems to prevent any expansion of the
content of \CurrentUser, because the page head now literally looks like
this:

 Compiled March 12, 2014 by \cldcontext {os.resultof"whoami"}.

I don't think I want to pass a backslash to Lua, so I'm not sure how to
apply what you're saying. Or are you using "Lua" here in the sense of
LuaTeX?

A backslash appears in the output of os.resultof"whoami"; do I need to
perform some processing on that output in order to escape backslashes?

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

[NTG-context] confusion about expansion

2014-03-12 Thread Lars Huttar 
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

\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.

[NTG-context] MP bounding box
