                'class': 'kepek'
            }

{% macro link(label, name, parameters = [], options = {}) %}

    {%

            activeClassName: 'active',
            attributes: {}
        }
    %}

    {% set options = defaults|merge(options) %}

    {% set isActive = app.request.attributes.get('_route') starts with name %}

    {% set url = url(name, parameters, options.schemeRelative)|default('#') %}

    {% set classList = ['route-link'] %}

    {% if isActive %}
        {% set classList = classList|merge([options.activeClassName]) %}
    {% endif %}

    {% set attributes = defaults.attributes|merge(options.attributes) %}

    {% if attributes.class is defined %}
        {% set classList = classList|merge([attributes.class]) %}
    {% endif %}

    {% set attributes = attributes|merge({ class: classList|join(' ') }) %}

    <a href="{{ url }}" {% for attrName, attrValue in attributes %}{{- attrName }}="{{ attrValue }}" {% endfor %}>
        {{ label|default(url) }}
    </a>
