Hi,
Is it possible to write somehow shorter using formatted output
and other library functions?
-----
import std.stdio, std.range;
void main() {
auto a = iota(100, 201);
writefln("%(;; %(%s, %),\n%).", [
a[0 .. 15],
a[15 .. 30],
a[30 .. 45],
a[45 .. 60],
a[60 .. 75],
a[75 .. 90],
a[90 .. $]
]);
}

I also want to know whether it is possible to D somehow set the
maximum width of the print string in characters?
-----
void main() {
import std.stdio, std.range;
writefln(";; %(%s, %)).", iota(10, 1101));
}
-----
For example, here's the code to Common Lisp which is given by the
width of the line is 30 characters:
-----
(let ((a (loop :for i :from 10 :to 1100 :collect i)))
(format t "~%;;~{ ~<~%;; ~1,30:;~S~>~^,~}.~%" a))

Looks like there's std.string.wrap to do that:

Yes, it's a lot better but I did not get to concatenate the
string ";;" in each paragraph:
-----
import std.conv, std.stdio, std.range, std.string;
void main() {
auto a = iota(10, 1101).text;
a = a[1 .. $ - 1], a ~= '.';
writeln(wrap(a, 30));
}

writeln(wrap(a, 30, ";; ", ";; "));
Works with dmd 2.066.1 and 2.067.0.
