# Typography Helper

The Typography Helper file contains functions that help your format text in semantically relevant ways.

## Loading this Helper

This helper is loaded using the following code:

`$this->load->helper('typography');`

The following functions are available:

## auto_typography()

Formats text so that it is semantically and typographically correct HTML. Please see the Typography Class for more info.

Usage example:

`$string = auto_typography($string);`

Note: Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted. If you choose to use this function you may want to consider caching your pages.

## nl2br_except_pre()

Converts newlines to <br /> tags unless they appear within <pre> tags. This function is identical to the native PHP nl2br() function, except that it ignores <pre> tags.

Usage example:

`$string = nl2br_except_pre($string);`
