I would like to pass the lua table keys and values to metapost. In the
keys i have information about the paths names and in the values i have
information about the label that should be draw in the center of each
path (unitsquare).
In my code (see attach) the table in question is
"weekdays_number_and_name".
I know that is possible to pass a array from metapost to lua. Is the
reverse possible?
it's possible to ask values from within mp:
\starttext
\startluacode
document.variables = {
labels = {
"one",
"two",
"three",
}
}
\stopluacode
\startMPpage
numeric dx, dy;
dx = 4.4cm;
dy = 0.53cm;
path b[];
for i=1 upto lua("mp.print(\#document.variables.labels)") :
b[i] = unitsquare xscaled dx yscaled dy shifted (0, (i-1)*dy);
draw b[i];
label(lua("mp.quoted(document.variables.labels[" & decimal i &
"])"), center b[i]);
endfor
\stopMPpage
\stoptext
