Twig Tweak
The module provides a Twig extension with some useful functions and filters.
Installation
Install as usual.
composer require drupal/twig_tweak
drush en twig_tweak
Usage
Drupal View
{{ drupal_view('who_s_new', 'block_1') }}

{{ drupal_view_result('who_s_new', 'block_1') }}
Drupal Block
In order to list all registered plugin IDs fetch them with block plugin manager. With Drush it can be done like follows:
drush ev "print_r(array_keys(\Drupal::service('plugin.manager.block')->getDefinitions()));"
{# Print block using default configuration. #}
{{ drupal_block('system_branding_block') }}
{# Print block using custom configuration. #}
{{ drupal_block('system_branding_block', {label: 'Branding', use_site_name: false, id}) }}
{# Bypass block.html.twig theming. #}
{{ drupal_block('system_branding_block', wrapper=false) }}
@see https://www.drupal.org/node/2964457#block-plugin

{{ drupal_dump(var) }}
{# Same as above but shorter. #}
{{ dd(var) }}
{# Dump all available variables for the current template. #}
{{ dd() }}
Drupal Title
{# The title is cached per URL. #}
{{ drupal_title() }}
Drupal URL
{# Basic usage. #}
{{ drupal_url('node/1') }}
{# Complex URL. #}
{{ drupal_url('node/1', {query: {foo: 'bar'}, fragment: 'example', absolute: true}) }}
Drupal Link
{# It supports the same options as drupal_url(), plus attributes. #}
{{ drupal_link('View'|t, 'node/1', {attributes: {target: '_blank'}}) }}
{# This link will only be shown for privileged users. #}
{{ drupal_link('Example'|t, '/admin', check_access=true) }}
Drupal Messages
{{ drupal_messages() }}
Drupal Breadcrumb
{{ drupal_breadcrumb() }}
Drupal Breakpoint
{# Make Xdebug break on the specific line in the compiled Twig template. #}
{{ drupal_breakpoint() }}

{# Basic usage. #}
<div class="contextual-region">
{{ drupal_contextual_links('entity.view.edit_form:view=frontpage&display_id=feed_1:') }}
{{ drupal_view('frontpage') }}
</div>
{# Multiple links. #}
<div class="contextual-region">
{{ drupal_contextual_links('node:node=123|block_content:block_content=123:') }}
{{ content }}
</div>
Token Replace
{# Basic usage. #}
{{ '<h1>[site:name]</h1><div>[site:slogan]</div>'|token_replace }}
{# This is more suited to large markup. #}
{% apply token_replace %}
<h1>[site:name]</h1>
<div>[site:slogan]</div>
{% endapply %}
Preg Replace
{{ 'Drupal - community plumbing!'|preg_replace('/(Drupal)/', '<b>$1</b>') }}
For simple string interpolation consider using built-in replace
or format
Twig filters.
Image Style
{# Basic usage #}
{{ 'public://images/ocean.jpg'|image_style('thumbnail') }}
{# Make sure to check that the URI is valid #}
{% set image_uri = node.field_media_optional_image|file_uri %}
{% if image_uri is not null %}
{{ image_uri|image_style('thumbnail') }}
{% endif %}
image_style
will trigger an error on invalid or empty URIs, to avoid broken
images when used in an <img>
tag.
Transliterate
{{ 'Привет!'|transliterate }}
Check Markup
{{ '<b>bold</b> <strong>strong</strong>'|check_markup('restricted_html') }}
Format size
{{ 12345|format_size() }}
Truncate
{# Truncates a UTF-8-encoded string safely to 10 characters. #}
{{ 'Some long text'|truncate(10) }}
{# Same as above but with respect of words boundary. #}
{{ 'Some long text'|truncate(10, true) }}
View
{# Do not put this into node.html.twig template to avoid recursion. #}
{{ node|view }}
{{ node|view('teaser') }}
{{ node.field_image|view }}
{{ node.field_image[0]|view }}
{{ node.field_image|view('teaser') }}
{{ node.field_image|view({settings: {image_style: 'thumbnail'}}) }}
With
This is an opposite of core without
filter.
{# Set top level value. #}
{{ content.field_image|with('#title', 'Photo'|t) }}
{# Set nested value. #}
{{ content|with(['field_image', '#title'], 'Photo'|t) }}
Children
<ul>
{% for tag in content.field_tags|children %}
<li>{{ tag }}</li>
{% endfor %}
</ul>
File URI
When field item list passed the URI will be extracted from the first item. In order to get URI of specific item specify its delta explicitly using array notation.
{{ node.field_image|file_uri }}
{{ node.field_image[0]|file_uri }}
Media fields are fully supported including OEmbed resources, in which case
it will return the URL to the resource, similar to the file_url
filter.
{{ node.field_media|file_uri }}
File URL
For string arguments it works similar to core file_url()
Twig function.
{{ 'public://sea.jpg'|file_url }}
In order to generate absolute URL set "relative" parameter to false
.
{{ 'public://sea.jpg'|file_url(relative=false) }}
{{ 'public://sea.jpg'|file_url(false) }}
When field item list passed the URL will be extracted from the first item. In order to get URL of specific item specify its delta explicitly using array notation.
{{ node.field_image|file_url }}
{{ node.field_image[0]|file_url }}
Media fields are fully supported including OEmbed resources.
{{ node.field_media|file_url }}
It is also possible to extract file URL directly from an entity.
{{ image|file_url }}
{{ media|file_url }}
PHP
PHP filter is disabled by default. You can enable it in settings.php file as follows:
$settings['twig_tweak_enable_php_filter'] = TRUE;
{{ 'return date('Y');'|php }}
Using PHP filter is discouraged as it may cause security implications. In fact it is very rarely needed. The above code can be replaced with the following.
{{ 'now'|date('Y') }}
