What is simple way to wrap a string into strings?

Eg from:
I went for a walk and fell down a hole.

To (6 max width):
I went
for a
walk
and
fell
down a
hole.

a common method works as follows. first you split your string into chunks where newlines might appear. e.g. after every space. then you keep track of a "line buffer", you keep adding chunks to the line buffer until it's too wide, then you remove one chunk and output the buffer as a line. rinse and repeat.

I'll get to work on some example code.

Actually, I did a search and found this. import std.string.wrap;

here you go: http://dpaste.dzfl.pl/e6e715c54c1b

do mind that this code has a couple issues, for example handing it a word longer than the break width will make it loop infinitely.

word wrap is a surprisingly hard problem, but I hope I gave you a good enough starting point.

Thanks Doxin. I going with the Phobos one, though. I've added your code to my large amount to of small programs.
