Hi all,

I need to pass a short text as parameter to a defintion. My problem is,
that the significant spaces are removed in this process. Hmm.....no clue.


% interface=en output=pdftex
\starttext

\def\TextWithSpaces#1{\framed{\obeyspaces#1}}%

% output is ok
\framed{\obeyspaces{A gap from here      to here!}}
% no big gap between 'here' and 'to'
\TextWithSpaces{A gap from here      to here!}

\stoptext


Any help is welcome.

Greetings,

Peter

A two-part solution is needed:

   \def\TextWithSpaces{\bgroup\obeyspaces\doTextWithSpaces}
   \def\doTextWithSpaces#1{\framed{#1}\egroup}

stupid me. \obeyspaces changes the cat-code of the space char, so...

i suggest that rolf adds en entry to the wiki, with the posted solutions, maybe we need a "how tex treats arguments" corner or so

just postpone argument loading

The spaces in front of the lines are not taken
into account for the two defined macros. What to do that
\obeyspaces is also valid for these ones?

\def\TextWithSpaces{\bgroup\obeyspaces\doTextWithSpaces}
\def\FramedTextWithSpaces{\framed\bgroup\obeyspaces\doTextWithSpaces}
\def\doTextWithSpaces#1{#1\egroup}

starttext
     A gap from here        to here!\par
\TextWithSpaces{   A gap from        here      to here!}

\framed{   A gap from here         to  here!}\par
\FramedTextWithSpaces{   A gap from        here      to here!}
\stoptext

current minimal
