+# Twig Tweak
+
+The Twig Tweak module provides a Twig extension with some useful functions
+and filters that can improve development experience.
+
+Some functions and filters are built in the Twig Tweak module, while others are
+simple wrappers to integrate Drupal functions and services into Twig (for
+example: `format_size`, `drupal_view_result`).
+
+## Requirements
+
+This module requires no modules outside of Drupal core.
+
+## Installation
+
+- Install as you would normally install a contributed Drupal module. For further
+information, see [Installing Drupal Modules](https://www.drupal.org/docs/extending-drupal/installing-drupal-modules).

+# Rendering blocks with Twig Tweak
+
+This subject is rather confusing because too many things in Drupal are referred
+to as "Blocks". So it is essential to understand what kind of block you are
+going to render. This guide covers three main cases you may deal when rendering
+blocks in a Twig template.
+
+## Block - plugin
+Technically speaking block plugin is a PHP class with a special annotation. See
+[Branding block plugin](https://git.drupalcode.org/project/drupal/-/blob/9.1.0/core/modules/system/src/Plugin/Block/SystemBrandingBlock.php#L16-22) as an example.
+
+The simplest way to render block plugin is as follows.
+```twig
+{{ drupal_block('plugin_id') }}
+```
+
+Optionally you can pass block label and plugin configuration in the second
+parameter.
+```twig
+{{ drupal_block('plugin_id', {label: 'Example'|t, some_setting: 'example', setting_array: {value: value}}) }}
+```
+
+By default, blocks are rendered using `block.html.twig` template. This can be
+turned off by setting wrapper parameter to false.
+```twig
+{{ drupal_block('plugin_id', wrapper=false) }}
+```
+
+The tricky thing here is figuring out block plugin ID. If you know which module
+provides a particular plugin, you can find its PHP class under the
+`MODULE_NAME/src/Plugin/Block` directory and locate the ID in the class
+annotation. For instance the plugin ID of login block can be found in the
+following file: `core/modules/user/src/Plugin/Block/UserLoginBlock.php`. When
+using the plugin ID, convert its format to snake_case (meaning the words are
+lowercase and separated by underscores e.g. `system_branding_block`).
+
+To look up all core block plugins use grep search.
+
+```shell
+grep -r ' id = ' core/modules/*/src/Plugin/Block/;'
+```
+
+However, this does not work for block types that are defined dynamically using
+plugin derivatives (like views blocks).
+
+The best way to get all registered plugin IDs is fetching them with block plugin
+manager
+```shell
+drush ev "print_r(array_keys(\Drupal::service('plugin.manager.block')->getDefinitions()));"
+```
+
+Note that the plugin_id needs to be wrapped in quotes. For example,
+```twig
+{{ drupal_block('system_breadcrumb_block') }}
+```
+
+## Block - configuration entity
+This is what we configure on `admin/structure/block` page. It's important to know
+that eventually these entities are rendered using block plugins described above.
+The purpose of the configuration entities is to store plugin IDs and
+configuration. Additionally, they reference theme and region where a block
+should be printed, but this data are not used when rendering through Twig Tweak.
+
+So having configured a block through administrative interface you can print it
+using the following code.
+```twig
+{{ drupal_entity('block', 'block_id') }}
+```
+
+Disabled blocks won't be printed unless you suppress access control as follows.
+
+```twig
+{{ drupal_entity('block', 'block_id', check_access=false) }}
+```
+
+Note that block_id here has nothing to do with 'block_plugin_id' we discussed
+before. It is an ID (machine_name) of block configuration entity. You may copy
+it from the block configuration form.
+
+The following Drush command will list all available block entities.
+```shell
+drush ev 'print_r(\Drupal::configFactory()->listAll("block.block."));'
+```
+
+## Block - content entity
+Content blocks, also known as custom blocks are configured on
+`admin/structure/block/block-content` page. Actually they have little to do with
+Drupal block system. These blocks are just content entities like node, user,
+comment and so on. Their provider (Custom block module) also offers a plugin to
+display them in blocks.
+
+The primary way to display content blocks is like follows.
+```twig
+{{ drupal_entity('block_content', 'content_block_id') }}
+```
+
+Though it looks similar to rendering configuration entities (Section 2), you
+should note two important distinctions.
+
+Entity type is 'block_content' not 'block'.
+Content block ID stands for an ID of respective content entity. This is a
+numeric value that can be found in URL when editing custom block. Getting
+content block IDs is as simple as executing a single SQL query.
+```shell
+drush sqlq 'SELECT id, info FROM block_content_field_data'
+```
+
+Since this method does not use block template (`block.html.twig`) you may need to
+supply block subject and wrappers manually.
+```twig
+<div class="block">
+  <h2>{{ 'Example'|t }}</h2>
+  {{ drupal_entity('block_content', content_block_id) }}
+</div>
+```
+
+Another way to accomplish this task is using block plugin (see Section 1).
+```twig
+{{ drupal_block('block_content:<uuid>', {label: 'Example'|t}) }}
+```
+
+Note that plugin ID in this case consists of entity type and entity UUID
+separated by a colon.
+
+It is also possible to create a configuration entity for this content block and
+print it as described in [Configuration entity section](#block-configuration-entity).

+# Cheat sheet
+
+## Drupal View
+```twig
+{{ drupal_view('who_s_new', 'block_1') }}
+```
+```twig
+{# Specify additional parameters which map to contextual filters you have configured in your view. #}
+{{ drupal_view('who_s_new', 'block_1', arg_1, arg_2, arg_3) }}
+```
+
+## Drupal View Result
+Checks results for a given view. Note that the results themselves are not printable.
+```twig
+{% if drupal_view_result('cart')|length == 0 %}
+  {{ 'Your cart is empty.'|t }}
+{% endif %}
+```
+
+## Drupal Block
+In order to figure out the plugin IDs list them using block plugin manager.
+With Drush, it can be done like follows:
+```shell
+drush ev "print_r(array_keys(\Drupal::service('plugin.manager.block')->getDefinitions()));"
+```
+```twig
+{# 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) }}
+
+{# For block plugin that has a required context supply a context mapping to tell the block instance where to get that context from. #}
+{{ drupal_block('plugin_id', {context_mapping: {node: '@node.node_route_context:node'}}) }}
+```
+
+See [rendering blocks with Twig Tweak](blocks.md#block-plugin) for details.
+
+## Drupal Region
+```twig
+{# Print 'sidebar_first' region of the default site theme. #}
+{{ drupal_region('sidebar_first') }}
+
+{# Print 'sidebar_first' region of Bartik theme. #}
+{{ drupal_region('sidebar_first', 'bartik') }}
+```
+
+## Drupal Entity
+```twig
+{# Print a content block which ID is 1. #}
+{{ drupal_entity('block_content', 1) }}
+
+{# Print a node's teaser. #}
+{{ drupal_entity('node', 123, 'teaser') }}
+
+{# Print Branding block which was previously disabled on #}
+{# admin/structure/block page. #}
+{{ drupal_entity('block', 'bartik_branding', check_access=false) }}
+```
+
+## Drupal Entity Form
+```twig
+{# Print edit form for node 1. #}
+{{ drupal_entity_form('node', 1) }}
+
+{# Print add form for 'article' content type. #}
+{{ drupal_entity_form('node', values={type: 'article'}) }}
+
+{# Print user register form. #}
+{{ drupal_entity_form('user', NULL, 'register', check_access=false) }}
+```
+
+## Drupal Field
+Note that drupal_field() does not work for view modes powered by Layout Builder.
+```twig
+{# Render field_image from node 1 in view_mode "full" (default). #}
+{{ drupal_field('field_image', 'node', 1) }}
+
+{# Render field_image from node 1 in view_mode "teaser". #}
+{{ drupal_field('field_image', 'node', 1, 'teaser') }}
+
+{# Render field_image from node 1 and instead of a view mode, provide an array of display options. #}
+{# @see https://api.drupal.org/api/drupal/core!lib!Drupal!Core!Entity!EntityViewBuilderInterface.php/function/EntityViewBuilderInterface%3A%3AviewField #}
+{{ drupal_field('field_image', 'node', 1, {type: 'image_url', settings: {image_style: 'large'}}) }}
+
+{# Render field_image from node 1 in view_mode "teaser" in English with access check disabled. #}
+{{ drupal_field('field_image', 'node', 1, 'teaser', 'en', FALSE) }}
+
+{# Render field_image from node 1 in view_mode "full" (default) with access check disabled (named argument). #}
+{{ drupal_field('field_image', 'node', 1, check_access=false) }}
+```
+
+## Drupal Menu
+```twig
+{# Print the top level of 'main' menu. #}
+{{ drupal_menu('main') }}
+
+{# Expand all menu links. #}
+{{ drupal_menu('main', expand=true) }}
+```
+
+## Drupal Form
+```twig
+{{ drupal_form('Drupal\\search\\Form\\SearchBlockForm') }}
+```
+
+## Drupal Image
+```twig
+{# Render image specified by file ID. #}
+{{ drupal_image(123) }}
+
+{# Render image specified by file UUID. #}
+{{ drupal_image('9bb27144-e6b2-4847-bd24-adcc59613ec0') }}
+
+{# Render image specified by file URI. #}
+{{ drupal_image('public://ocean.jpg') }}
+
+{# Render image using 'thumbnail' image style and custom attributes. #}
+{{ drupal_image('public://ocean.jpg', 'thumbnail', {alt: 'The alternative text'|t, title: 'The title text'|t}) }}
+
+{# Render image using 'thumbnail' image style with lazy/eager loading (by attribute). #}
+{{ drupal_image('public://ocean.jpg', 'thumbnail', {loading: 'lazy'}) }}
+{{ drupal_image('public://ocean.jpg', 'thumbnail', {loading: 'eager'}) }}
+
+{# Render responsive image (using a named argument). #}
+{{ drupal_image('public://ocean.jpg', 'wide', responsive=true) }}
+```
+
+## Drupal Token
+```twig
+{{ drupal_token('site:name') }}
+```
+
+## Drupal Config
+```twig
+{{ drupal_config('system.site', 'name') }}
+```
+
+## Drupal Dump
+```twig
+{# Basic usage. #}
+{{ drupal_dump(var) }}
+
+{# Same as above but shorter. #}
+{{ dd(var) }}
+
+{# Dump all available variables for the current template. #}
+{{ dd() }}
+```
+
+## Drupal Title
+```twig
+{# The title is cached per URL. #}
+{{ drupal_title() }}
+```
+
+## Drupal URL
+```twig
+{# The function accepts a valid internal path, such as "/node/1", "/taxonomy/term/1", a query string like "?query," or a fragment like "#anchor". #}
+
+{# Basic usage. #}
+{{ drupal_url('node/1') }}
+
+{# Complex URL. #}
+{{ drupal_url('node/1', {query: {foo: 'bar'}, fragment: 'example', absolute: true}) }}
+```
+
+## Drupal Link
+```twig
+{# 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 to the privileged users. #}
+{{ drupal_link('Example'|t, '/admin', check_access=true) }}
+```
+
+## Drupal Messages
+```twig
+{{ drupal_messages() }}
+```
+
+## Drupal Breadcrumb
+```twig
+{{ drupal_breadcrumb() }}
+```
+
+## Drupal Breakpoint
+```twig
+{# Make Xdebug break on the specific line in the compiled Twig template. #}
+{{ drupal_breakpoint() }}
+```
+
+## Contextual Links
+```twig
+{# 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
+```twig
+{# 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
+```twig
+{{ 'Drupal - community plumbing!'|preg_replace('/(Drupal)/', '<b>$1</b>') }}
+```
+For simple string interpolation consider using built-in `replace` or `format`
+Twig filters.
+
+## Image Style
+```twig
+{# 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
+```twig
+{{ 'Привет!'|transliterate }}
+```
+
+## Check Markup
+```twig
+{{ '<b>bold</b> <strong>strong</strong>'|check_markup('restricted_html') }}
+```
+
+## Format size
+Generates a string representation for the given byte count.
+```twig
+{{ 12345|format_size }}
+```
+
+## Truncate
+```twig
+{# 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
+```twig
+{# 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 and adds properties instead of removing it.
+```twig
+{# Set top-level value. #}
+{{ content.field_image|with('#title', 'Photo'|t) }}
+
+{# Set nested value. #}
+{{ content|with(['field_image', '#title'], 'Photo'|t) }}
+```
+
+## Data URI
+The filter generates a URL using the data scheme as defined in [RFC 2397](https://datatracker.ietf.org/doc/html/rfc2397)
+```twig
+{# Inline image. #}
+<img src="{{ '<svg xmlns="http://www.w3.org/2000/svg"><rect width="100" height="50" fill="lime"/></svg>'|data_uri('image/svg+xml') }}" alt="{{ 'Rectangle'|t }}"/>
+{# Image from file system. #}
+<img src="{{ source(directory ~ '/images/logo.svg')|data_uri('image/svg+xml') }}" alt="{{ 'Logo'|t }}"/>
+```
+
+## Children
+```twig
+<ul>
+  {% for tag in content.field_tags|children %}
+    <li>{{ tag }}</li>
+  {% endfor %}
+</ul>
+```
+
+## File URI
+When field item list is 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.
+```twig
+{{ 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.
+```twig
+{{ node.field_media|file_uri }}
+```
+
+## File URL
+For string arguments it works similar to core `file_url()` Twig function.
+```twig
+{{ 'public://sea.jpg'|file_url }}
+```
+
+In order to generate absolute URL set "relative" parameter to `false`.
+```twig
+{{ 'public://sea.jpg'|file_url(false) }}
+```
+
+When field item list is 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.
+```twig
+{{ node.field_image|file_url }}
+{{ node.field_image[0]|file_url }}
+```
+
+Media fields are fully supported including OEmbed resources.
+```twig
+{{ node.field_media|file_url }}
+```
+
+It is also possible to extract file URL directly from an entity.
+```twig
+{{ image|file_url }}
+{{ media|file_url }}
+```
+
+## Entity URL
+Gets the URL object for the entity.
+See \Drupal\Core\Entity\EntityInterface::toUrl()
+```twig
+{# Creates canonical URL for the node. #}
+{{ node|entity_url }}
+
+{# Creates URL for the node edit form. #}
+{{ node|entity_url('edit-form') }}
+```
+
+## Entity Link
+Generates the HTML for a link to this entity.
+See \Drupal\Core\Entity\EntityInterface::toLink()
+```twig
+{# Creates a link to the node using the node's label. #}
+{{ node|entity_link }}
+
+{# Creates link to node comment form. #}
+{{ node|entity_link('Add new comment'|t, 'canonical', {fragment: 'comment-form'}) }}
+```
+
+## Entity translation
+That is typically needed when printing data from referenced entities.
+```twig
+{{ media|translation.title|view }}
+```
+
+## Cache metadata
+When using raw values from entities or render arrays it is essential to
+ensure that cache metadata are bubbled up.
+```twig
+<img src="{{ node.field_media|file_url }}" alt="Logo"/>
+{{ content.field_media|cache_metadata }}
+```
+
+## PHP
+PHP filter is disabled by default. You can enable it in `settings.php` file as
+follows:
+```php
+$settings['twig_tweak_enable_php_filter'] = TRUE;
+```
+```twig
+{{ '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.
+```twig
+{{ 'now'|date('Y') }}
+```

+# Migrating to Twig Tweak 3.x
+
+Twig Tweak 3.x branch is mainly API compatible with 2.x
+Below are known BC breaks that may require updating your Twig templates.
+
+## Dependencies
+Twig Tweak 3.x requires Drupal 9, Twig 2 and PHP 7.3.
+
+## Rendering entities
+
+### Entity ID is now required
+Entity ID parameter in `drupal_entity()` and `drupal_field()` functions is now
+mandatory. Previously it was possible to load entities from current route by
+omitting entity ID parameter. However, that was making Twig templates coupled
+with routes and could cause caching issues.
+
+Before:
+```twig
+{{ drupal_entity('node', null, 'teaser') }}
+```
+
+After:
+```twig
+{{ drupal_entity('node', node.id, 'teaser') }}
+```
+
+In case a template does not contain a variable with entity object you may
+prepare it in a preprocess hook.
+```php
+/**
+ * Implements hook_preprocess_page().
+ */
+function preprocess_page(array &$variables): void {
+  $variables['entity'] = \Drupal::routeMatch()->getParameter('entity_type');
+}
+```
+
+### Default view mode has changed
+The view mode parameter in `drupal_field()` has changed from `default` to `full`. If you are using `drupal_field()` without specifying a view mode, you should update your templates to specify the `default` one.
+
+Before:
+```
+{{ drupal_field('field_name', 'node', node.id) }}
+```
+
+After:
+```
+{{ drupal_field('field_name', 'node', node.id, 'default') }}
+```
+
+## Rendering blocks
+`drupal_block()` now moves attributes provided by block plugin to the outer
+element. This may break some CSS rules.
+
+Before:
+```html
+<div>
+  <div class="from-block-plugin">Block content</div>
+</div>
+```
+
+After:
+```html
+<div class="from-block-plugin">
+  <div>Block content</div>
+</div>

+# Using Twig Tweak to extend Views module functionality
+
+Twig Tweak's `drupal_view()` method provides access to embed views within any
+Twig code, including dynamically from within each row of another view. This
+feature provides an alternate method to accomplish the nesting provided by the
+[Views Field View](https://www.drupal.org/project/views_field_view) module.
+
+The most basic syntax for Twig Tweak's view embed simply specifies the view, and
+the machine name you wish to embed, as follows:
+```twig
+{{ drupal_view('who_s_new', 'block_1') }}
+```
+
+You can, however, also specify additional parameters which map to contextual
+filters you have configured in your view.
+```twig
+{{ drupal_view('who_s_new', 'block_1', arg_1, arg_2, arg_3) }}
+```
+
+## Nested View Example
+There are a lot of cases in views where you want to embed a list inside each
+row. For example, when you have a list of product categories (taxonomy terms)
+and for each category, you want to list the 3 newest products. In this example,
+assume your content type is 'product', and has a reference field to a taxonomy
+named 'product categories'.
+
+### Step1: Create your child view
+Create a view of the content of type 'product', and choose to create a block
+displaying an unformatted list of teasers, with 3 items per block. In this
+example, we'll use a view name of 'products_by_category'.  Once the view is
+created, choose advanced and add a relationship to the taxonomy term that
+references 'product categories', and choose to require the relationship. Next,
+choose to add a "Contextual Filter" for "Term ID", and choose an action for when
+the filter value is not available (e.g. display contents of no results found).
+Set your desired sort and save your view.
+
+### Step 2: Create your parent view
+Create a view of taxonomy terms of type 'product categories', and choose to
+create a page which displays an unformatted list of fields. Once this is
+created, you should see the preview showing all the product categories. Choose
+to add a field of type "Term ID", and choose "Exclude from display"; this is
+necessary to make the term id available to the next field which uses Twig Tweak.
+Now, choose to add a field of type "Custom text" from the "Global" category.
+Inside that field, enter the Twig Tweak call to display the child view we
+created above, passing the tid as a contextual filter, as such:
+```twig
+{{ drupal_view('products_by_category', 'block_1', tid) }}
+```
+
+You should now save your view, and be able to access the URL you assigned and
+see a list of product categories, each followed by the three most recent
+products within each.
+
+This example can be applied to any nested view scenario, including
+multiple-levels of nesting.
+
+## Check if the view has results
+```twig
+{% set view = drupal_view_result('related', 'block_1')|length %}
+{% if view > 0 %}
+  {{ drupal_view('related', 'block_1') }}
+{% endif %}
+```
