Hi Hans, Hi all,
the new ConTeXt (2000.01.26) writes mpgraph.mp with error.
mp breaks with:
>> _data_prefix_
>> "mpd-"
! Equation cannot be performed (numeric=string).
<to be read again>
;
l.5 _data_prefix_ := "mpd-" ;
the same goes for : _data_suffix_ := ".tmp" ;
My input file is:
\startuseMPgraphic{Fig 1}
linejoin:=mitered;
for i = 0 upto 4:
z[i]=(7cm*sind(i*360/5),7cm*cosd(i*360/5));
endfor;
draw z0--z1--z2--z3--z4--cycle;
draw z0..z1..z2..z3..z4..cycle;
pickup pencircle scaled 1.5pt;
draw z2--z3--(x3,y0)--(x2,y0)--cycle;
\stopuseMPgraphic
\starttext
\useMPgraphic{Fig 1}
\stoptext
Greetings
Lutz

Hm. Are you sure you have mp-tool.mp in the right location?
For the moment, change this at the and of core-mps.tex:
\appendtoks
if not known _data_prefix_ :
string _data_prefix_ , _data_suffix_ ;
fi ;
_data_prefix_ := "\bufferprefix mpd-" ;
_data_suffix_ := ".tmp" ;
\to \MPinitializations
or put the next line at the top of your file:
\prependtoks
if not known _data_prefix_ :
string _data_prefix_ , _data_suffix_ ;
fi ;
\to \MPinitializations
I'll add an additional safeguard to the next version.
BTW, I uploaded a new version a few days ago. That one has (1) a date fix,
since I introduced a bug when I added the low level calendar macros, as
well as a better way to embed mp graphics in xforms (pdf), i.e. in first
quadrant. More precise in viewers.
