[NTG-context] MP/Lua binding information flow
In the code in the attachment I have intend that everytime the data generated by Lua are updated metapost should make immediately their representation. However, it insists into represent only the last data generated. How can I fix this problem? thanks Jorge calltemplates.tex Description: TeX document ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
Re: [NTG-context] MP/Lua binding (was: Pass a lua table to metapost)
Hello Hans,
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
is there a doc where to study MP/Lua binding (mp members; examples) - like the manual
ConTeXt Lua Documents?
Here we can see Lua mp.print() and mp.quoted() usage...
Best regards,
Lukas
