[NTG-context] MetaPost bug? in MKIV
The following example produces expected output with MKII (texexec) but
fails the compilation process with MKIV (context).
\startuseMPgraphic{foo}
input graph;
path p;
gdata(data.d, $, augment.p($1,$2););
draw begingraph(4in,2.5in);
gdraw p;
endgraph;
\stopuseMPgraphic
\starttext
\useMPgraphic{foo}
\stoptext
The data stored in data.d is as follows:
0 0
1 1
2 4
When compiling with MKIV, the following error occurs:
!mplib : mp terminal:
(/opt/context-minimals/tex/texmf/metapost/base/graph.mp
! Redundant equation.

Re: [NTG-context] MetaPost bug? in MKIV
Hi Troy,
I don't have the graph.mp file, but I have seen similar errors here. I
guess if you change the lines into
Gmargin.low:=-.07;
Gmargin.high:=1.07;
things work again. Sorry, I can't remember the reason why equations
cause trouble in mplib. But I'm quite sure that this is only an
incompatibility and not a bug.
Best wishes, Peter

Re: [NTG-context] MetaPost bug? in MKIV
When using \startMPinclusions input graph; \stopMPinclusions or not even including the MPinclusions at all (and thus not doing `input graph;') seems to give the same result.

The log of what happens during the compile process is attached. i tried your example (found graph.mp) and i got a bunch of errors regarding wrong picture color model, redundant equations and unknown transform components. #color problem is probably here def Gwithpc_(expr q) = withpen penpart q withcolor (redpart q, greenpart q, bluepart q) enddef; Another difference is the way text is handled in mkiv. In particular, color (withcolor) is not applied to metapost text. #redundant equations use ':=' for constants, etc. # unknown transform components (0,0,_tt_w_1,0,0,1) ! Transform components aren't all known. is this a problem with textext()? looks very cryptic to me. anyhow, in the current form graph.mp does not work with mplib.
