Hi,

What's the D's idiom to split a string into an array of every n chars? (prefer one liner)

Thanks.

One way you can do it:

import std.range : chunks;
import std.algorithm : map;
import std.array : array;
import std.conv : text;

string[] split = "Hello D".chunks(2).map!(v => v.text).array;
writeln(split);

foreach(val; "Hello D".chunks(2)) {
    writeln(val.text);
}

str.byChar.chunks(2).array;

Your request of "array of every n chars" is somewhat ambiguous. This is an array of chunks (not an array of arrays).
