Subject: How to run Typesetting in MetaPost example (MetaFun)?
Date: Tue, 18 Jan 2011 14:48:50 +0100	[thread overview]
Message-ID: <4D359A42.4030209@ziggo.nl> (raw)

Hi,

I wanted to try (using ConTeXt minimals MkIV) the example on page 228 of 
the MetaFun manual, dealing with typesetting in MetaPost.

The code is given as:

\resetMPdrawing
\startMPdrawing
 picture pic[] ;
 numeric wid[], len[], pos[], n ;
 wid[0] := len[0] := pos[0] := n := 0 ;
\stopMPdrawing

\def\whatever#1%
 {\appendtoks#1\to\MPtoks
  \setbox\MPbox=\hbox{\bfd\the\MPtoks}%
  \startMPdrawing
   n := n + 1 ; len[n] := \the\wd\MPbox ;
  \stopMPdrawing
  \startMPdrawing[-]
   pic[n] := textext("\bfd\setstrut\strut#1") ;
   pic[n] := pic[n] shifted - llcorner pic[n] ;
  \stopMPdrawing}

\handletokens MetaPost is Fun!\with\whatever

But is won't run. The following message is generated:

\@@toks ->\MPtoks

\dodoappendtoks ->\dodoglobal \@@toks
                                      \@EAEAEA {\@EA \the \@EA \@@toks 
\the ...
\whatever #1->\appendtoks #1\to \MPtoks
                                        \setbox \MPbox =\hbox {\bfd \the 
\MP...
\dodohandletokenstwo *#1->\dododohandletokens {#1}
                                                  \dohandletokens
<argument> M
            etaPost is Fun!
\handletokens ...ndletokens {#2}\dohandletokens #1
                                                  \end
l.96 \handletokens MetaPost is Fun!\with\whatever

Anybody any idea?

Regards,
Gerard Verhaag
