I know that metapost can send the variables "version", "number",
"string", "point", "quad", "boolean" and "path" to Context.
"triplet" variable can't pass. It will be very usefull if metapost can
send a array to context.
\startMPcode
numeric x[];
for i = 1 upto 10: x[i]:=random; endfor
passvariable("array",x);
passvariable("version","1.0") ;
passvariable("number",x[1]) ;
passvariable("string","whatever") ;
passvariable("point",(1,2)) ;
passvariable("triplet",(1,2,3)) ;
passvariable("quad",(1,2,3,4)) ;
passvariable("boolean",false) ;
passvariable("path",fullcircle scaled 1cm) ;
\stopMPcode
\ctxluacode{inspect(metapost.variables)}
\ctxcommand{mprunvar("array")}
Thanks in advance
that's less trivial (as automatism) so i provide passarrayvariable now
(next beta) ... of course the next request would concern complex arrays
so i also made a more low level flusher
\starttext
\startMPcode
numeric n[] ; for i=1 upto 10: n[i] := i + 1 ; endfor ;
path p[] ; for i=1 upto 10: p[i] := fullcircle scaled (i*cm) ;
endfor ;
numeric n[][] ; for i=1,4 : for j=1,3 : n[i][j] = uniformdeviate(1)
; endfor ; endfor ;
passvariable("x",12345) ;
passarrayvariable("n-array",n,1,7,1) ;
passarrayvariable("p-array",p,1,7,1) ;
passvariable("p",(1,1) .. (2,2)) ;
