I also want to know whether it is possible to D somehow set the
maximum width of the print string in characters?
I got to do this:
-----
import std.stdio, std.range, std.conv, std.array;
void formatWidthIotaToStr(ref string formatStr, int[] inputRange)
{
formatStr ~= ";;";
int formatWidth = 30, lenStr = formatStr.length;
foreach (e; inputRange) {
lenStr += e.text.length;
if (lenStr < formatWidth) {
lenStr += 2;
formatStr ~= ' ', formatStr ~= e.text, formatStr ~= ',';
}
else {
formatStr ~= "\n;; ", formatStr ~= e.text, formatStr ~=
',';
lenStr = e.text.length + 5;
}
}
formatStr.length -= 1;
formatStr ~= '.';
}
void main() {
auto a = iota(10, 1101).array;
string s;
formatWidthIotaToStr(s, a);
writeln(s);
}
