wordwrap

• 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.

  PHP

  $string = "The quick brown fox jumped over the lazy dog.";
  $result = wordwrap($string, 20, "<br />\n");
  var_export($result);
  // => "The quick brown fox<br />\njumped over the lazy<br />\ndog."

  Ruby

  string = "The quick brown fox jumped over the lazy dog."
  string.gsub(/(\w.{1,20})(\s+)/s, "\\1<br />\n")
  # => "The quick brown fox<br />\njumped over the lazy<br />\ndog."

  Rails includes a built-in helper method to perform word wrap operations in your views.

  Rails

  <%= word_wrap "The quick brown fox jumped over the lazy dog.", 20 %>

  Produces:

  The quick brown fox
  jumped over the lazy
  dog.
