there's nothing in your program that breaks lines differently
from the input. If you've a Unicode-aware terminal it should
really work as it is. If 'cat Jekyll1' doesn't produce the same
output as this program... then there must be some right-to-left
work that needs to happen that I'm aware of.
If what you're wanting to do is to *reshape* text so that it
prints with proper word-breaks across lines according to the
current size of the terminal, then you've got to do this work
yourself. On Unix a simple shortcut might be to print through
fmt(1) instead:
```d
void main() {
import std.process : pipeShell, Redirect, wait;
auto fmt = pipeShell("fmt", Redirect.stdin);
scope (exit) {
fmt.stdin.close;
wait(fmt.pid);
}
char[15] longword = 'x';
foreach (i; 1 .. 10) {
fmt.stdin.writeln(longword);
}
}
```
which outputs:
```
xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx
xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx xxxxxxxxxxxxxxx
xxxxxxxxxxxxxxx
```
or... oh, there's std.string.wrap. With the same output:
```d
void main() {
import std.string : wrap;
import std.stdio : write;
enum longtext = {
char[15] longword = 'x';
string result;
foreach (i; 1 .. 10)
result ~= ' ' ~ longword;
return result;
}();
write(longtext.wrap(72));
}
```
These tools might not do what you want with that language, though.
