* 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.

* The machine-readable name of the type (group) of token being replaced, such

* @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.

* replacement values, as supplied in the $data parameter to
* \Drupal\Core\Utility\Token::replace().

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

* 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

* replacements from the tokens defined here.
*
* @return
* 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.
