 /**
  * Text pattern plugin for TinyMCE
  *
  * @since 4.3.0
  *
  * This plugin can automatically format text patterns as you type. It includes several groups of patterns.
  *
  * Start of line patterns:
  *  As-you-type:
  *  - Unordered list (`* ` and `- `).
  *  - Ordered list (`1. ` and `1) `).
  *
  *  On enter:
  *  - h2 (## ).
  *  - h3 (### ).
  *  - h4 (#### ).
  *  - h5 (##### ).
  *  - h6 (###### ).
  *  - blockquote (> ).
  *  - hr (---).
  *
  * Inline patterns:
  *  - <code> (`) (backtick).
  *
  * If the transformation in unwanted, the user can undo the change by pressing backspace,
  * using the undo shortcut, or the undo button in the toolbar.
  *
  * Setting for the patterns can be overridden by plugins by using the `tiny_mce_before_init` PHP filter.
  * The setting name is `wptextpattern` and the value is an object containing override arrays for each
  * patterns group. There are three groups: "space", "enter", and "inline". Example (PHP):
  *
  * add_filter( 'tiny_mce_before_init', 'my_mce_init_wptextpattern' );
  * function my_mce_init_wptextpattern( $init ) {
  *   $init['wptextpattern'] = wp_json_encode( array(
  *      'inline' => array(
  *        array( 'delimiter' => '**', 'format' => 'bold' ),
  *        array( 'delimiter' => '__', 'format' => 'italic' ),
  *      ),
  *   ) );
  *
  *   return $init;
  * }
  *
  * Note that setting this will override the default text patterns. You will need to include them
  * in your settings array if you want to keep them working.
