cropping text

cropping text

[Peter Rolf]

Hi all,

I've used \doboundtext so far, to crop my text exactly as I want it. But
now I've problems with text, that contains a \underbar token. It seems,
that \handletokens can't handle \underbar.

The other cropping alternative, \limitatetext, perfectly works with
\underbar, but it's useless for me, as it cropps off only at word
boundaries. mhh..

Is there an (more or less) easy way to solve my problem?
I don't need a full solution; any hints are welcome.

Thanks in advice,

Peter

here is a full solution; it's up to you to add documentation to the wiki 
(the macro will be in the next release)

\def\limitatefirstline#1#2#3%
  {\hbox\bgroup\strut
   \setbox\scratchbox\hbox{#1}%
   \ifdim\wd\scratchbox>#2\relax
     \setbox\scratchbox\hbox{#3}%
     \hsize#2\relax
     \advance\hsize-\wd\scratchbox
     \setbox\scratchbox\vbox{\forgetall#1}%
     \setbox\scratchbox\vsplit\scratchbox to \lineheight
     \vbox{\unvbox\scratchbox}%
     #3%
   \else
     #1%
   \fi
   \egroup}

\starttext

\limitatefirstline{\input tufte\relax}{10cm}{\unknown}

\stoptext

Many thanks! I'll add the text cropping stuff to the wiki as soon as
possible.

Greetings,
