ISBN formatter extension for Twig
=================================

[](#isbn-formatter-extension-for-twig)

Based on `nicebooks/isbn`, this tiny package provides two Twig filters such that ISBNs can be formatted simply.

Installation
------------

[](#installation)

Just run `composer require nicohaase/twig-isbn-formatter`

Available filters
-----------------

[](#available-filters)

- `formatIsbn` will add dashes where neccessary
- `toIsbn13` will provide a ISBN-13 out of any valid (ie. ISBN-10 or ISBN-13) input

Examples
--------

[](#examples)

- `{{"9783411040162"|formatIsbn}}` will output `978-3-411-04016-2`
