Inside ConTeXt

Inside ConTeXt

[Wolfgang Schuster]

After reading the following code [1] from the wiki again I will  
present here my solution:

\def\TextWithSpaces{\framed\bgroup\afterassignment\obeyspaces\let\next}

With a small modification optional arguments are possible.

   \def\TextWithSpaces#1#{\framed#1\bgroup\afterassignment\obeyspaces 
\let\next}

This allows:

   \TextWithSpaces{A gap from here to there!}

and

   \TextWithSpaces[foregroundstyle=bold]{A gap from here to there!}

Hi Wolfgang,

I appreciate your solution, but it would be much more useful if the 
solution would be accompanied with a step-by-step explanation of what is 
going on behind the scenes.

A collection of such elegant solutions (together with explanations) 
would be an invaluable source of knowledge for those of us who want to 
learn the TeX programming.

It's magic and mages don't explain their tricks :)

Can you please first take a look in a TeX manual (TeXbook, TeX by  
Topic or TeX for the impatient) and ask then what you don't  
understand, for my example look at the explanation of \afterassignment.

Wolfgang
