{{notice: This function's solution will only work within the context of the Rails framework. }}
There is no native wordwrap function in Ruby, but we can achieve similar
results with the String.gsub method.
{{code:php
$string = "The quick brown fox jumped over the lazy dog.";
$result = wordwrap($string, 20, "
\n");
var_export($result);
// => "The quick brown fox
\njumped over the lazy
\ndog."
}}
{{code:ruby
string = "The quick brown fox jumped over the lazy dog."
string.gsub(/(\w.{1,20})(\s+)/s, "\1
\n")
# => "The quick brown fox
\njumped over the lazy
\ndog."
}}
Rails includes a built-in helper method to perform word wrap operations in your views.
{{code:rails <%= word_wrap "The quick brown fox jumped over the lazy dog.", 20 %> }}
Produces:
{{code:html The quick brown fox jumped over the lazy dog. }}
