\stretched{foo \bar} problems with expansion of \bar

\stretched{foo \bar} problems with expansion of \bar

[Tobias Burnus]

Hi,

First I'd like to thank Taco for the calculation work, it works
like a charm :-)

I have a seemingly simple problem (which is probably simple, but I don't
have access to the TeXbook at the moment).

I have:
  \def\Semester{Wintersemester 2001/2002}
  \stretcheduppercase{VORLESUNGSKRITIK ZUM \Semester}
  \bye

Well, the \Semester is not expanded before the stretching is done.

Thus I have
  V O R L E S U N G S K R I T I K   Z U M  Wintersemester 2001/2002
instead of
  V O R L E S U N G S K R I T I K   Z U M   W I N T E R S E M E S T E R ...

Using \stretched instead of \stretcheduppercase produces error messages
(grouping). I experimented a bit with \expandafter, but I failed.

Tobias

 Probably not the ConTeXt way to go, but for me it works to do:
\def\Semester{Wintersemester 2001/2002}
\edef\text{VORLESUNGSKRITIK ZUM \Semester}
\expandafter\stretcheduppercase\expandafter{\text}
\bye

\expanded{\stretcheduppercase{VORLESUNGSKRITIK ZUM \Semester}}

Should work.

this is indeed the way to go; for those unfamiliar with the \expanded macro 
(not a primitive): the first thing encountered is *not* expanded, which is 
what one often wants, like in

   \expanded{\somekindofcommand{the stuff to be expanded}

it even works well in cases like:

   \expanded{\somecommand[first not yet expanded arg]}[second already 
expanded arg]

which is more unreadable but faster than

   \expanded{\somecommand[....][...]}

i something should not be expanded inside \expanded, precede it by 
\noexpand (except for the first token)
