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?

Hi,
I'm in need of help to get the example as described in the MetaFun manual running, because I want to use text around a path!
So, I started reading the chapter about 'Typesetting in METAPOST' and wanted to try the examples as given in that chapter, but without succes!
The problem seem to be the MPtoks macro. According to the text in this chapter this low level macro (and MPbox and appendtoks) are already defined, but are they really?
The version of context minimals I use at the moment is:

Any suggestions are very much welcomed! Thanks in advance!
Hi Gerard, how about an alternative way to deal with this? 1. draw the text with Inkscape (put text on a path); I think there is even a tutorial for this. 2. select the graphic and save it as *.eps 3. use pstoedit to convert it into *.mp pstoedit -v -ssp -f "mpost:" foo.eps foo.mp 4. edit/scale the metapost graphic as you like Best wishes, Peter
