+# wordwrap
+
+Wraps a string to a column width, the default is 80. As an optional
+second parameter, you can specify a string of text to wrap the text to
+the next line, the default is a carriage return `"\n"`. By default,
+`wordwrap` will attempt to wrap at a word boundary. If you want to cut
+off at the exact character length, pass the optional third parameter as
+TRUE. This is equivalent to the PHP
+[`wordwrap()`](https://www.php.net/wordwrap) function.
+
+## Basic usage
+```smarty
+{$myVar|wordwrap:30}
+```
+
+## Parameters
+
+| Parameter Position | Type    | Required | Default | Description                                                                                   |
+|--------------------|---------|----------|---------|-----------------------------------------------------------------------------------------------|
+| 1                  | integer | No       | 80      | This determines how many columns to wrap to.                                                  |
+| 2                  | string  | No       | \\n     | This is the string used to wrap words with.                                                   |
+| 3                  | boolean | No       | FALSE   | This determines whether to wrap at a word boundary (FALSE), or at the exact character (TRUE). |
+
+## Examples
+
+```php
+<?php
+
+$smarty->assign('articleTitle',
+                "Blind woman gets new kidney from dad she hasn't seen in years."
+               );
+
+```
+
+Where template is
+
+```smarty
+{$articleTitle}
+
+{$articleTitle|wordwrap:30}
+
+{$articleTitle|wordwrap:20}
+
+{$articleTitle|wordwrap:30:"<br />\n"}
+
+{$articleTitle|wordwrap:26:"\n":true}
+```
+
+Will output:
+
+```html
+Blind woman gets new kidney from dad she hasn't seen in years.
