Question: how to read that grid from a text file?
I don't know the cause of your problem. While investigating it I have filed another bug:
http://d.puremagic.com/issues/show_bug.cgi?id=8260In the meantime this (a bit scary) code solves your reading problem:
import std.stdio, std.algorithm, std.range, std.conv; void main() { const grid = File("table.txt") .byLine().map!(r => std.algorithm.splitter(r) .map!(to!int)() .array())() .array(); writeln(grid); } Bye, bearophile
