How to make an active menu?

Question

symfony

It is required to set the .selected class to the active menu item, as well as remove the link.
How to do it correctly and concisely (without JS)?

homepage:
    path: /
    defaults: { _controller: SiteAppBundle:Main:index }
download:
    path: /download
    defaults: { _controller: SiteAppBundle:Main:download }
entry:
    path: /entry/{name}
    defaults: { _controller: SiteAppBundle:Main:entry }

<li><a href="{{ path('homepage') }}">HOME</a></li>
<li><a href="{{ path('entry', {'name': 'info'}) }}">INFO</a></li>
<li><a href="{{ path('entry', {'name': 'settings'}) }}">SETTINGS</a></li>
<li><a href="{{ path('download') }}">DOWNLOAD</a></li>

UPD
Created variables in main template:

{% set route = app.request.get('_route') %}
{% set entry = app.request.get('_route') == 'entry' ? app.request.get('_route_params').name : '' %}

Moved the menu to menu.html.twig and included it in the main template.
Then the usual check through {% if %}

<li>{% if route == 'homepage' %}HOME{% else %}<a href="{{ path('homepage') }}">HOME</a>{% endif %}</li>
<li>{% if entry == 'info' %}INFO{% else %}<a href="{{ path('entry', {'name': 'info'}) }}">INFO</a>{% endif %}</li>
<li>{% if entry == 'settings' %}SETTINGS{% else %}<a href="{{ path('entry', {'name': 'settings'}) }}">SETTINGS</a>{% endif %}</li>
<li>{% if route == 'download' %}DOWNLOAD{% else %}<a href="{{ path('download') }}">DOWNLOAD</a>{% endif %}</li>

p.s. Unfortunately, through the Twig extension, use the test like this:

{% if 'homepage' is is_page %}текущая страница "homepage"{% endif %}

1. symfony.com/doc/current/bundles/KnpMenuBundle/inde...
2. If you don’t want to connect third-party bundles, then you can do something like this (but it doesn’t smell brevity here):

{% if app.request.attributes.get('_route') == 'homepage' %}
    <li class="selected"><span>HOME</span></li>
{% else %}
    <li><a href="{{ path('homepage') }}">HOME</a></li>
{% endif %}

{% if app.request.attributes.get('_route') == 'entry' and
    app.request.attributes.get('_route_params').name is defined and
    app.request.attributes.get('_route_params').name == 'info' %}
    <li class="selected"><span>INFO</span></li>
{% else %}
    <li><a href="{{ path('entry', { 'name': 'info' }) }}">INFO</a></li>
{% endif %}

{% if app.request.attributes.get('_route') == 'entry' and
    app.request.attributes.get('_route_params').name is defined and
    app.request.attributes.get('_route_params').name == 'settings' %}
    <li class="selected"><span>SETTINGS</span></li>
{% else %}
    <li><a href="{{ path('entry', { 'name': 'settings' }) }}">SETTINGS</a></li>
{% endif %}

{% if app.request.attributes.get('_route') == 'download' %}
    <li class="selected"><span>DOWNLOAD</span></li>
{% else %}
    <li><a href="{{ path('download') }}">DOWNLOAD</a></li>
{% endif %}
