Do not cache Twig template

Twig compiled templates are cached by default. To auto refresh the compiled template, in settings.php, add this line:

define('AT_DEBUG', TRUE);

Do not enable this on production sites.

Call service method:

{# call: Class_Name::getValue() #}
{{ fn__at_container('server.name').value() }}
{{ 'Is same to: ' ~ fn__at_container('server.name').getValue() }}

Get available variables

{{ attribute(get_defined_vars(), 'context')|kpr }}

Render View with template:

{{ 'view_name'|drupalView({template: '@my_module/templates/views/view_name.html.twig'}) }}

To minimize your time on view template, just extends to default view template:

{% extends '@at_base/templates/views_view.html.twig' %}

{% block debug %}
  {{ attribute(get_defined_vars(), 'context')|dsm }}
{% endblock %}

Render entity with custom template

{% set o = { template: '@atest_base/templates/entity/user.html.twig' } %}
{{ 'user:1'|drupalEntity(o) }}
