tex placeholder for use in metapost/metafun

tex placeholder for use in metapost/metafun

[Martin 'golodhrim' Scholz]

Hi everybody,

as I like to desing a CI for an publishing Cover for an Organisation, I 
have a question about usage:

What I wanna do is, having placeholders in the metapost coverpage, it 
should work like

\author{}
\title{}
\swlogo{}

in the preamble

and should be automatically placed in the metapost graphic at runtime....

what would be the best way to do that?

I thought about

\def\author{content}


and then in metapost \btex\author\etex

but not sure if it will work, or is there a more ConTeXtian way to do 
so...

Thanks for your help

You can set the values with

\setvariables
  [document]
  [author=...,
   title=...,
   logo=...]

and access them with

\getvariable{document}{author}

You can also test for a content of the variable:

\doifvariable{document}{logo}{\externalfigure[\getvariable{document}{logo}]}
