func WrapString ¶

func WrapString(s string, lim uint) string

WrapString wraps the given string within lim width in characters.

Wrapping is currently naive and only happens at white-space. A future version of the library will implement smarter wrapping. This means that pathological cases can dramatically reach past the limit, such as a very long word.
