following simple code:

<li><a href="{{ path('_list') }}">List</a></li>

is there a simple way to add an class="active" if the current page matches the _list route?

using the newest PR-Release of symfony2 and twig as template engine

Twig allows for conditionals and the Request object is available throughout the application. If you are including the template, to get the route you want to use:

app.request.attributes.get('_route')

If you are using the render function, you want to use:

app.request.attributes.get('_internal')

With that, you should be able to use:

class="{% if app.request.attributes.get('_route') == '_list' %}active{% endif %}"

or shorter:

class="{{ app.request.get('_route') == '_list' ? 'active' }}"
