/**
 * Provide replacement values for placeholder tokens.
 *
 * This hook is invoked when someone calls
 * \Drupal\Core\Utility\Token::replace(). That function first scans the text for
 * [type:token] patterns, and splits the needed tokens into groups by type.
 * Then hook_tokens() is invoked on each token-type group, allowing your module
 * to respond by providing replacement text for any of the tokens in the group
 * that your module knows how to process.
 *
 * A module implementing this hook should also implement hook_token_info() in
 * order to list its available tokens on editing screens.
 *
 * @param $type
 *   The machine-readable name of the type (group) of token being replaced, such
 *   as 'node', 'user', or another type defined by a hook_token_info()
 *   implementation.
 * @param $tokens
 *   An array of tokens to be replaced. The keys are the machine-readable token
 *   names, and the values are the raw [type:token] strings that appeared in the
 *   original text.
 * @param array $data
 *   An associative array of data objects to be used when generating replacement
 *   values, as supplied in the $data parameter to
 *   \Drupal\Core\Utility\Token::replace().
 * @param array $options
 *   An associative array of options for token replacement; see
 *   \Drupal\Core\Utility\Token::replace() for possible values.
 * @param \Drupal\Core\Render\BubbleableMetadata $bubbleable_metadata
 *   The bubbleable metadata. Prior to invoking this hook,
 *   \Drupal\Core\Utility\Token::generate() collects metadata for all of the
 *   data objects in $data. For any data sources not in $data, but that are
 *   used by the token replacement logic, such as global configuration (e.g.,
 *   'system.site') and related objects (e.g., $node->getOwner()),
 *   implementations of this hook must add the corresponding metadata.
 *   For example:
 *   @code
 *     $bubbleable_metadata->addCacheableDependency(\Drupal::config('system.site'));
 *     $bubbleable_metadata->addCacheableDependency($node->getOwner());
 *   @endcode
 *
 *   Additionally, implementations of this hook, must forward
 *   $bubbleable_metadata to the chained tokens that they invoke.
 *   For example:
 *   @code
 *     if ($created_tokens = $token_service->findWithPrefix($tokens, 'created')) {
 *       $replacements = $token_service->generate('date', $created_tokens, ['date' => $node->getCreatedTime()], $options, $bubbleable_metadata);
 *     }
 *   @endcode
 *
 * @return array
 *   An associative array of replacement values, keyed by the raw [type:token]
 *   strings from the original text. The returned values must be either plain
 *   text strings, or an object implementing MarkupInterface if they are
 *   HTML-formatted.
 *
 * @see hook_token_info()
 * @see hook_tokens_alter()

/**

 *
 * Tokens are placeholders that can be put into text by using the syntax

 * token is the machine-readable name of a token within this group. This hook
 * provides a list of types and tokens to be displayed on text editing screens,
 * so that people editing text can see what their token options are.
 *
 * The actual token replacement is done by
 * \Drupal\Core\Utility\Token::replace(), which invokes hook_tokens(). Your
 * module will need to implement that hook in order to generate token
 * replacements from the tokens defined here.
 *
 * @return array
 *   An associative array of available tokens and token types. The outer array
 *   has two components:
 *   - types: An associative array of token types (groups). Each token type is
 *     an associative array with the following components:
 *     - name: The translated human-readable short name of the token type.
 *     - description (optional): A translated longer description of the token
 *       type.
 *     - needs-data: The type of data that must be provided to
 *       \Drupal\Core\Utility\Token::replace() in the $data argument (i.e., the
 *       key name in $data) in order for tokens of this type to be used in the
 *       $text being processed. For instance, if the token needs a node object,
 *       'needs-data' should be 'node', and to use this token in
 *       \Drupal\Core\Utility\Token::replace(), the caller needs to supply a
 *       node object as $data['node']. Some token data can also be supplied
 *       indirectly; for instance, a node object in $data supplies a user object
 *       (the author of the node), allowing user tokens to be used when only
 *       a node data object is supplied.
 *   - tokens: An associative array of tokens. The outer array is keyed by the
 *     group name (the same key as in the types array). Within each group of
 *     tokens, each token item is keyed by the machine name of the token, and
 *     each token item has the following components:
 *     - name: The translated human-readable short name of the token.
 *     - description (optional): A translated longer description of the token.
 *     - type (optional): A 'needs-data' data type supplied by this token, which
 *       should match a 'needs-data' value from another token type. For example,
 *       the node author token provides a user object, which can then be used
 *       for token replacement data in \Drupal\Core\Utility\Token::replace()
 *       without having to supply a separate user object.
