Just register it as a service.

Warning: If you are using Symfony < 2.4, don't use this declaration, but the next one.

    twig.extension.onpath:
        class: Alcalyn\Extension\Twig\OnPath
        calls:
            - [ setRequestStack, [ @request_stack ] ]
        tags:
            - { name: twig.extension }

For Symfony < 2.4:

    twig.extension.onpath:
        class: Alcalyn\Extension\Twig\OnPath
        scope: request
        calls:
            - [ setRequest, [ @request ] ]
        tags:
            - { name: twig.extension }

Using

You can do in your Twig template:

{{ 'Hello'|onpath('home', 'user-index') }}

That displays 'Hello' only if you are on one of these routes: home, user-index.

Note: You can enter more routes names.

So you can do for example in a menu navbar:

<nav>
    <ul>
        <li class="{{ 'active'|onpath('home') }}">
            <a href="{{ path('home') }}">Home</a>
        </li>
        <li class="{{ 'active'|onpath('blog', 'blog_post', 'blog_comment') }}">
            <a href="{{ path('blog') }}">Blog</a>
        </li>
        <li class="{{ 'active'|onpath('about') }}">
            <a href="{{ path('about') }}">About</a>
        </li>
    </ul>
</nav>
