Installation

Install the Twig integration with Composer:

composer require alto/twig-code-highlight

The package requires PHP 8.4 or later, Twig 3.28 or later, and ALTO Code Highlight 1.x. Composer installs Code Highlight and its mbstring and tokenizer extension requirements.

In a standalone script, load vendor/autoload.php. Then register both the extension and its runtime loader as shown in Getting started.
