+/**
+ * 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.
