Hi.
I'm running Debian/GNU (unstable) and was trying to get the following
file to work:
\setupcolors[state=start]
\starttext
Bla
\startuseMPgraphic{bla}
u := 1cm;
z0 = (0,0);
z1 = (0,1)*u;
z2 = (1,1)*u;
z3 = (1,0)*u;
draw z0--z1--z2--z3--cycle;
z4 = whatever[z0,z2] = whatever[z1,z3];
dotlabel.bot(btex $z_4$ etex,z4);
\stopuseMPgraphic
\startuseMPgraphic{blubb}
z0 = (0,0);
z1 = (0,1)*u;
z2 = (1,1)*u;
z3 = (1,0)*u;
draw z0--z1--z2--z3--cycle;
z4 = whatever[z0,z2] = whatever[z1,z3];
dotlabel.bot(btex $z_{42}$ etex,z4);
\stopuseMPgraphic
\useMPgraphic{bla}
\useMPgraphic{blubb}
Blubb
\stoptext
When the dotlabel-Lines do not use btex..etex, "texexec --pdf" works
just fine, creating mpgraph.{1,2}. But if I use btex, the files are
not created. I think I found the reason for this. When texexec calls
etex to typeset the labels, the file mpgraph.mp is overwritten with a
simple "end." Now, texexec keeps a backup of it but seems to restore
it too late. I've moved the specific lines futher ahead. Now
everything seems to work fine.
Is this a correct patch or am I missing something?
Greetings,
Dennis
